? usually mentioned fields of mathematics, i. e. , geometry, arithmetic, astron- omy, optics, music, etc. , but rather by its likeness and relationship to these disciplines. It is similar to geometry in that it uses figures and symbols, to music in its chants, to arithmetic in its numbers and manipulations, to astronomy in its concerns for times and motions, and to optics in making observations. In general, it is similar to mathematics as a whole, either because it mediates between divine and natural actions, or because it shares or lacks something of both. For some things are intermediates because they participate in both extremes, others because they are excluded from both extremes, in which case they should not be called intermediates but a third species which is not between the other two but outside of them. From what has been said, it is clear how divine and physical magic differ from the third type.
To turn now to the particulars, magicians take it as axiomatic that, in all the panorama before our eyes, God acts on the gods; the gods act on the celestial or astral bodies, which are divine bodies; these act on the spirits who reside in and control the stars, one of which is the earth; the spirits act on the elements, the elements on the compounds, the compounds on the senses; the senses on the soul, and the soul on the whole animal. This is the descending scale.
By contrast, the ascending scale is from the animal through the soul to the senses, through the senses to compounds, through compounds to the elements, through these to spirits, through the spirits in the elements to those in the stars, through these to the incorporeal gods who have an ethereal substance or body, through them to the soul of the world or the spirit of the universe; and through that to the contemplation of the one, most simple, best, greatest, incorporeal, absolute and self-sufficient being.
Thus, there is a descent from God through the world to animals, and an ascent from animals through the world to God. He is the highest point of the scale, pure act and active power, the purest light. At the bottom of the scale is matter, darkness and pure passive potency, which can become all things from the bottom, just as He can make all things from the top. Between the highest and lowest levels, there are intermediaries, the higher of which have a greater share of light and action and active power, while the lower levels have a greater share of darkness, potency and passive power.
As a result, all light in lower things, which comes to them from above, is more powerful in higher things. And also, all darkness in higher things is stronger in lower things. But the nature and power of light and darkness
? ? ?
On magic
? are not equal. For light diffuses and penetrates through the lowest and deepest darkness, but darkness does not touch the purest sphere of light. Thus, light penetrates and conquers darkness and overflows to infinity, while darkness does not penetrate or overwhelm or equal the light, but rather is very weak compared to light.
Parallel to the three types of magic mentioned above, there are three different worlds to be distinguished: the archetypal, the physical and the rational. Friendship and strife are located in the archetypal world, fire and water in the physical world, and light and darkness in the mathematical world. Light and darkness descend from fire and water, which in turn descend from peace and strife. Thus, the first world produces the third world through the second, and the third world is reflected in the first through the second.
Leaving aside those principles of magic which play on the superstitious and which, whatever they be, are unworthy of the general public, we will direct our thoughts only to those things which contribute to wisdom and which can satisfy better minds. Nevertheless, no type of magic is unwor- thy of notice and examination, because every science deals with the good, as Aristotle says in the introduction to his De anima,4 and as Thomas and other more contemplative theologians agree. Nevertheless, all this should be kept far away from profane and wicked people and from the multitudes. For nothing is so good that impious and sacrilegious and wicked people cannot contort its proper benefit into evil.
In general, there are two types of efficient cause: nature and the will. The will is threefold: human, spiritual and divine. Nature, as used here, is twofold: intrinsic and extrinsic. Furthermore, intrinsic nature is of two kinds: matter or the subject, and form with its natural power. Extrinsic nature is also of two kinds: the first, which is preferably called an image of nature, is a trace and shadow or light which remains in a thing within its body, like light and heat in the sun and in other hot bodies; the second emanates and radiates from a subject, like light, which flows from the sun and is found in illuminated things, and like heat, which resides with light in the sun and is also found in heated bodies.
By examining the number of these causes, we can descend to the differentiation of powers or of effects produced by the first cause through the intermediate causes down to the closest and lowest ones, by restricting the universal cause, which, itself, does not attend to any one available
4 Aristotle, De anima, ? , ? (? ? ? . a. ? -? ). ? ? ?
? On magic
? subject rather than another. For, although this cause and its causal power always remain immutably the same, it produces contrary (and not just different) effects in different subjects with the help of different types of matter. As a result, there need be only one such simple, principal efficient cause, like there is only one sun, one heat and one light, which by turning forward or backward, by approaching and receding, mediately and imme- diately causes the winter, the summer, and their different and contrary weather, and the ordering of the seasons.
Matter is also derived from this same cause, if we wish to believe those who think that the four commonly mentioned elements change into each other. The originator of this view was Plato, who sometimes says that all things were produced from one matter and one efficient cause. But what- ever may have been the method of production used by the first universal cause, and whether one assumes only one or many material principles, any human or spiritual secondary cause must recognize that, because of the great multitude and variety of producing species, there are many types of matter having act or form, through which a subject is able to influence things outside of itself.
In regard to the powers or forms or accidents which are transmitted from subject to subject, some are observable, for example, those that belong to the genus of active and passive qualities, and the things that immediately follow from them, like heating and cooling, wetting and drying, softening and hardening, attracting and repelling. Others are more hidden because their effects are also obscure, for example, to be happy or sad, to experience desire or aversion, and fear or boldness. These are said to be caused by external impressions acting on the cognitive power in humans and on the estimative power in animals. Thus, when a child or infant sees a snake, or when a sheep sees a wolf, it conceives an image, without any other experience, of hostility and of fear of its own death or destruction.
The explanation of this is to be found in the internal sense, which is, indeed, moved by the external impressions, although indirectly. For nature gives not only existence to each species, but also the desire in each individ- ual to preserve itself in its present state. Thus, it implants in each thing an internal spirit, or sense, if you prefer that word, by which as from an inter- nal dictate it recognizes and avoids great dangers. This can be seen not only in the examples given above, but also in all things in which, even if they seem to be defective or dead, there still resides a spirit striving with all its power to conserve the present condition. This happens in falling drops
? ? ?
On magic
? of liquids which form a sphere to avoid disintegration, and also in falling bodies which are attracted to a centre and tend to gather their parts into a sphere lest they break up and disperse. This is also found in pieces of straw or wood thrown on a fire, and in thin tissues and membranes, which recoil to avoid, somehow, their own destruction.
This particular sense is located in all things and is a form of life, although, in accordance with the common custom, we do not call it an ani- mal, which refers to a specific soul, because these components cannot be called animals. Nevertheless, in the order of the universe, one can recog- nize that there is one spirit which is diffused everywhere and in all things, and that everywhere and in all things there is a sense of grasping things which perceives such effects and passions.
Just as our soul produces, originally and in a general way, all vital activities from the whole body, and even though the whole soul is in the whole body and in each of its parts, nevertheless, it does not produce every action in the whole body or in each of its parts. Rather, it causes vision in the eyes, hear- ing in the ears and taste in the mouth (but if the eye were located in any other place, we would see in that place, and if the organs of all the senses were located in any one place, we would perceive everything in that place). In the same way, the soul of the world is in the whole world, and is every- where so adapted to matter that, at each place, it produces the proper sub- ject and causes the proper actions. Therefore, although the world soul is located equally everywhere, it does not act equally everywhere, because matter is not arranged to be equally disposed to it everywhere. Thus, the whole soul is in the whole body, in the bones and in the veins and in the heart; it is no more present in one part than in another, and it is no less pre- sent in one part than in the whole, nor in the whole less than in one part. Rather, it causes a nerve to be a nerve in one place, a vein to be a vein else- where, blood to be blood, and the heart to be the heart elsewhere. And as these parts happen to be changed, either by an extrinsic efficient cause or by an intrinsic passive principle, then the activity of the soul must also change.
This is the most important and most fundamental of all the principles which provide an explanation of the marvels found in nature; namely, that because of the active principle and spirit or universal soul, nothing is so incomplete, defective or imperfect, or, according to common opinion, so completely insignificant that it could not become the source of great events. Indeed, on the contrary, a very large disintegration into such components must occur for an almost completely new world to be generated from them.

? While bronze is more similar to gold and is closer to the distinctive prop- erties of gold than are the ashes of bronze, still, in a transmutation, these ashes of bronze are closer to the form of gold than is bronze. Likewise, we see that all seeds, which are oriented to producing a particular species, hap- pen to be rather alike as though they were of the same, and not different, species, since they are similar and distinctive and related. He who believes otherwise is like someone who thinks that an ape can be changed into a human more easily than the seed, implanted in a woman, which previously was food and bread.
Nevertheless, in every production, there must be present a similarity and a form of the same species. Just as a house or a garment results from a model in the maker's mind in the case of artefacts, likewise, in the productions of nature, a species of things is generated and defined by the exemplar, which is distinctive of the matter which generates the form. For example, we see the same types of food, and the same heavens, water and houses reproduced in substance: a dog into a dog, a human into a human, a cat into a cat. And a dog generates the same species of dog, and a human the same species of human.
From this, it is clear that the entire cause of the differences is due to an idea, which is generally present everywhere in nature, and which is later limited to this or that species, depending on whether one or other species resembles the idea more. As a result, any magician who wishes to carry out his work in accordance with nature must especially understand this ideal principle and how it applies specifically to species, numerically to numbers and individually to individuals. From this, he formulates an image and the proportions of the matter so formed, and with good reasons reinforces the result with the wisdom and power of his magic. Many also bring about cures and injuries by connecting symbols with particular components or by appealing to those who communicate with or take part in curing or destructive forces. In this way, the work of magic is restricted and applied to a particular individual.
Leaving aside other arguments, it is clear from these experiences that every soul and spirit has some degree of continuity with the universal spirit, which is recognized to be located not only where the individual soul lives and perceives, but also to be spread out everywhere in its essence and substance, as many Platonists and Pythagoreans have taught. As a result, vision grasps the most distant things immediately and without motion, and, indeed, the eye, or some part thereof, extends immediately to the stars or immediately from the stars to the eye.
? ? ?
On magic
? Furthermore, the soul, in its power, is present in some way in the entire universe, because it apprehends substances which are not included in the body in which it lives, although they are related to it. Thus, if certain impediments are excluded, the soul has an immediate and sudden presence with the most distant things, which are not joined to it by any motion, which nobody would deny, but rather are directly present in a certain sense.
Experience teaches this also in the case of those whose nose has been cut off; if they arrange to grow a new nose for themselves from the flesh of some other animal, and if that animal whose flesh was used dies, then as the body of that animal rots, so does the borrowed nose. From this, it is clear that the soul diffuses outside of the body in every aspect of its nature. 5 It also follows that the soul knows not only the members of its own body, but also everything for which it has any use, participation, or interaction.
There is no value in the stupid argument, advanced by those who lack true philosophical principles, that a thing which is touched by something else does not itself perceive that. Indeed, in one sense, this is true if we are distinguishing between species or individuals, but it is false if we are dis- tinguishing one bodily part from another. For example, if someone injures a finger or pricks one part of the body with a pin, the whole body is imme- diately disturbed everywhere and not just in that part where the injury occurred.
And so, since every soul is in contact with the universal soul, it is not pos- sible to find in this case the same effects which occur in bodies which do not mutually penetrate into each other. Rather, for spiritual substances, a different comparison is needed. For instance, if innumerable lamps are lit, they all act together as though they were one light, and no one light impedes or reflects or excludes another. The same thing happens when many voices are diffused through the same air, or if many visible rays, to use the common saying, spread out to reveal the same visible whole. All these rays pass through the same medium, and while some move in straight lines and others obliquely, they do not interfere with each other. In the same way, innumerable spirits and souls, when spread out through the same space, do not interfere with each other such that the diffusion of one would affect the diffusion of an infinity of others.
This power belongs not only to the soul but also to certain accidents, like sound, light and vision. The reason is that the whole soul is located in the whole body and in every part of the body, and that the whole soul
5 This is Thesis ? ? in Bruno's Theses de magia. See his Opera latine conscripta, ? ? ? , ? ? ? . ? ? ?
? On magic
? apprehends all things, however diverse and distant, which are around it outside of its body. This is a sign that the soul is not included in the body as its first act and substance,6 and that it is not circumscribed by the body. Rather, in itself and by itself, it should be understood only as a second act. This principle is the cause of innumerable marvellous effects, although its nature and power need to be investigated. This soul and divine substance cannot be inferior to the accidents which issue from it as its effects, traces and shadows. I declare that if the voice operates outside the body which produces it, and enters as a whole into innumerable ears on all sides, then why cannot the whole substance, which produces the voice which is tied to certain organs of the body, be located in different places and parts?
Furthermore, it must be noted that occult intelligence is not heard or understood in all languages. For the voices spoken by humans are not heard in the same way as the voices of nature. As a result, poetry, especially of the tragic type (as Plotinus says), has a very great effect on the wavering thoughts of the soul.
Likewise, not all writings have the same impact as those markings which signify things by the particular way in which they are drawn and config- ured. Thus, when certain symbols are arranged in different ways, they rep- resent different things: in a circle, the attraction of love; when opposed, the descent into hate and separation; when brief, defective and broken, they point to destruction; when knotted, to bondage; when strung out, to dis- solution. Furthermore, these symbols do not have a fixed and definite form. Rather, each person, by the dictate of his own inspiration or by the impulse of his own spirit, determines his own reactions of desiring or rejecting something. And thus, he characterizes for himself each symbol according to his own impulse, and as the divine spirit personally exerts cer- tain powers which are not expressed in any explicit language, speech, or writing.
Such were the figures, so well designed by the Egyptians, which are called hieroglyphics or sacred symbols. These were specific images selected from natural objects and their parts to designate individual things. The Egyptians used these symbols and sounds to converse with the gods to accomplish extraordinary results. Later, when Theuth,7 or someone else, invented the letters of the type we use today for other purposes, this
6 This sentence is an explicit rejection of Aristotle's definition of the soul in De anima, ? ? , ? (? ? ? . a. ? ? -? ? ).

? resulted in a tremendous loss, first of memory, and then of divine science and magic.
Like those Egyptians, magicians today formulate images, written sym- bols and ceremonies, which consist of certain actions and cults, and through which they express and make known their wishes with certain sig- nals. This is the language of the gods which, unlike all other languages which change a thousand times every day, remains always the same, just as natural species remain always the same.
For the same reasons, the spirits speak to us through visions and dreams, but we claim that these are enigmas, because of our unfamiliarity and igno- rance and weak capacities, even though they are the very same sounds and very same expressions used for representable things. Just as these sounds elude our grasp, likewise our Latin, Greek and Italian sounds sometimes fail to be heard and understood by the higher and eternal spirits, which differ from us in species. Thus, it is no easier for us to be able to commu- nicate with the spirits than it is for an eagle to converse with a human. Just as there can be conversation and agreement only by means of gestures between two groups of humans who do not share a common language, like- wise, there can be communication between us and certain types of spirits only by the use of certain signs, signals, figures, symbols, gestures and other ceremonies. The magician, especially when using the kind of magic which is called 'theurgy', can hardly accomplish anything without such sounds and symbols.
On the communion and interaction of things
From the above, one can understand and explain how interaction occurs not only between things which, to the senses, are near each other, but also between things which are far apart. For, as was said above, things are united by a universal spirit which is present as a whole in the whole world and in each of its parts. As a result, just as different lights come together in the same space, likewise, the souls of the universe, whether they be finite or infinite in number, interact in their powers and activities. However, this does not happen to bodies, because they are limited and circumscribed by their surfaces and surroundings, and because they are composed of innu- merably different parts in different bodies and places (if we can speak of place rather than space. ) Therefore, no body can act on another body, and no matter on other matter, nor can the material parts of one body act on the
? ? ?
On magic
? parts of another body, but rather, all action comes from quality and form and ultimately from soul. The soul first changes the dispositions, and then the dispositions change bodies. Thus, bodies act on distant bodies, on nearby ones and on their own parts, by means of a certain harmony, joining and union which comes from form. For, since every body is governed by a soul or a spirit which connects its parts, and since one soul acts on another nearby soul in any direction and wherever it is, it follows necessarily that a soul moves that body, wherever it is, because it is controlled by, and subor- dinate to, that soul. Whoever is aware of this indissoluble continuity of the soul and its necessary connection to a body will possess an important principle both to control natural things and to understand them better.
From this follows clearly the reason why a void, i. e. , a space empty of any body, does not exist. For no body can leave one place without being replaced by another. During life, the soul does leave its own body, but it cannot leave the universal body, nor can it be abandoned by the universal body, if you prefer to state it that way. For, when it leaves one simple or complex body, it moves into another simple or complex body, or from one body left behind, it goes to and enters into another. Thus, it has an indis- soluble connection with universal matter. And since its own nature is to be a continuous whole everywhere, we realize that it exists together with a material body everywhere. From this, we conclude that the void does not exist in the sense of a space with no matter in it, but rather a void is a space in which different bodies move and succeed each other. It also follows that the motion of the parts of one body towards the parts of another body is continuous. Motion occurs through a continuous space which is not inter- rupted by any void located between full spaces, unless we wish to say that a space in which there is no sensible body is a void.
A continuous body is an unobservable body, that is, an airy or ethereal spirit. It is very active and very powerful and very similar to the soul, and it is quite different from the dense sluggishness found in observable, com- posite substances. The above mentioned powers of unobservable spiritual bodies are the source of all the powers in observable bodies themselves. Indications of this are the airy spirit which agitates and embroils all the seas, and the invincible force of the winds which, even when they are rather calm and quiet, disturb the earth, break trees and destroy houses. Lucretius put it well when he said that it is this spiritual body which performs all actions in observable things. 8 Many philosophers have thought that this
8 Lucretius, De rerum natura, ? , ? ? ? ff. ? ? ?
? On magic
? spiritual body is the same thing as the soul, and the poet has said that this air 'has the power of fire and the soul'. 9
Furthermore, fire, which does not consist of dense matter like coal, which is rather an ignited body, is to be understood as different from air only accidentally. For true fire is, indeed, a spirit, which is sluggish when it is located in an ignited body, but it is lively when it is outside of an ignited body, and it is a form of motion in a flame or in some intermediate state.
This spirit, acting in different ways, forms different bodies and animals. And although not all composite bodies are animals, it must be noted that all animals have a soul which is of the same type in all the members of one genus. However, that soul is not actuated in one and the same way because of differences in the dispositions of matter and in objective ideals. From this, it follows that, since there are different and contrary forms, there are also differences and reasons why some animals congregate with each other, being attracted and impelled to various places, while others flee from or pursue each other. All of this is due to the way they are structured.
All things desire to preserve their own existence, and thus they forcibly and unwillingly resist separation from the place where they exist and per- severe. This force is so strong that the sun or fire attracts water to itself through airy space only after it has first made the water like air, that is, by converting it into a vapour. After that has happened, then the substance which was water is attracted willingly, and by means of the same impulse of attraction, it tries to adapt itself so that it slowly becomes more and more like fire, and finally, it becomes fire itself. On the other hand, that most sub- tle body which is contained in the spirit in the form of fire changes back into water by the opposite sequence as it congeals and thickens.
Therefore, the same substance and matter changes from water to vapour, from vapour to air, and from air to the thinnest and most penetrating ethe- real body. The latter has been called a 'spirit' by the Egyptians, Moses and Dionysius of Apollonia, although they differ because Moses did not distinguish spirit from soul (according to his words; I do not judge his meaning), which the others did. The other substance [earth] is dry and composed of atoms, which are very solid and indissoluble bodies. In them- selves, they are neither continuous nor divisible and, thus, cannot be changed into any other body. And the substance of water or spirit or air, which is the same, never changes into the substance of atoms or dry earth, nor vice versa.
9 Virgil, Aeneid, ? ? ? ? , ? ? ? . ? ? ?
? On magic
? This philosophy is supreme, divine and true, since it is quite in agree- ment with nature by positing the following principles of reality: first, water or the abyss or the Styx; second, dryness or atoms or earth (I am not speak- ing of the terrestrial globe); third, spirit or air or soul; fourth, light. These are so different from each other that one cannot be transformed into the nature of another, although they do come together and associate, sometimes more or less, sometimes all or some of them.
On the double motion of things and on attraction
There are two kinds of motion, natural and preternatural. Natural motion comes from an intrinsic principle, while preternatural motion is from an extrinsic principle; natural motion is in harmony with the nature, struc- ture and generation of things, preternatural motion is not. The latter is twofold: violent, which is against nature, and ordered or structured, which is not contrary to nature. What is commonly called natural motion is found in all genera or in all the categories, leaving out the distinction between motion and mutation. 10
For now, we omit all the other classes of motion and their species and consider only natural motion in place. One type of this is possessed by nat- ural things and does not move a thing away from it own proper place; this is circular motion, or a version thereof. The other type is straight line motion, which is not naturally possessed by natural things. For example, air moves in a straight line to fill a void. A stone moves through air, and a body which is heavier than water moves through water, in a straight line in order to occupy the place in which it either is at rest or moves naturally. And as much as it can, a contrary flees from its contrary in a straight line, for example, fumes, vapour and water from fire (for it goes faster to a greater distance through a straight line). Likewise, similar and agreeable things tend towards each other in a straight line, for example, straw to amber, and iron to a magnet, so that they can rest together or move better and more easily.
There is also a third type of local motion, which is an inflow and an outflow found in all natural things when any of their parts are ejected in various ways and in every direction. For now, we will call this 'spher- ical' motion. For it does not occur either in a straight line, or to or from
? 10 This is an Aristotelian distinction in which 'motion' refers to changes in quality, quantity and place, while 'mutation' refers to changes in substance or essence.
? ? ?
On magic
? or around a centre. Rather, it occurs along an infinity of lines from the same centre, for while some parts of the body are ejected and emitted outward from the body's convex surface and perimeter, others are recipro- cally received and absorbed. Bodies grow and are invigorated when the inflow of beneficial things is greater than their outflow, and they age and weaken and become sluggish when the inflow of extraneous things is greater than the outflow of natural things. This is the reason why cor- ruption and change occur in things, including all changes or alterations and disintegrations . . . 11
There is no controversy over the evidence for the first two types of motion, and, as a result, the understanding and classifications of them are well known. But a more careful consideration of the third type will be found to be not only needed and helpful, but also necessary. The situation is especially clear in things which have very strong sensible qualities. For instance, fire warms in every direction and not just on one side or another. For, as soon as it is lighted, it sends out its light and flames in every direc- tion. Likewise, a sound and a voice penetrate equally in all directions, if they occur in a medium which is open on all sides. In the same way, it is quite clear that the sense of smell is activated by the continuous emission of small parts from an odoriferous body. This could not happen unless that body's substance were to flow out and emit its parts in all directions. The same thing happens in the case of reflections and other such observable occurrences. Innumerable other accidental things are caused by certain parts flowing out, and sometimes these parts travel an enormous distance from a very small observable source, as is clear when a small amount of something emits a smell for many years.
In addition to these observable qualities or powers which are emitted from bodies spherically, there are other, more spiritual and less heavy ones which act not only on the body and on the senses, but also on the interior spirit. The more powerful ones touch the powers of the soul and cause various effects and passions, as is commonly thought to be true of many stones, herbs and minerals. This is also clear in fantasies and in cases where the eye has actively or passively been hit. An example is the basilisk12 who, by looking at a man a long way off, can kill him with the sharpness of its vision.
? 11 There is a break in Bruno's text at this point.
12 The basilisk, also called a cockatrice, was a legendary monster resembling a lizard which was said to
have been hatched by a snake from a cock's egg. Its breath and glance were supposedly fatal.

? How a magnet attracts iron, coral attracts blood, etc.
What was said above explains why magnets naturally attract things. There are two kinds of attraction. The first occurs by agreement, as when parts move to their proper place and are oriented to that place, and when simi- lar and harmonious things attract each other. The second type occurs with- out agreement, as when contraries come together because the one which cannot escape is overwhelmed, as when moisture is attracted by fire. This is clear in the case of a burning object being held above a bowl containing water, where the water is sucked up by the heat and rises rapidly. The same thing happens when waterspouts and hurricanes occur at sea, with the result that sometimes even ships are thrown a great distance upwards by the waves.
Attraction occurs in three ways. The cause of the first type is clear to the senses, as is shown in the cases mentioned above. This also happens when the attraction and absorption of air attract objects contained in the air. This is, likewise, evident in pipes through which water is sucked, and thus rises to any level. This happens for the reason given. For if the air in the tube is attracted, and if there is no other air to take its place, then water or earth or something else will fill that space. If nothing can replace it, then the air would be held back and retained by the power of the vacuum, as is clear when an opening is obstructed by objects being sucked in and swallowed. Another example occurs when the tongue and lips are held together and their opening is very tightly compressed around the mediating air, and vice versa, when one sucks so that there is elicited from the mouth's pores a spirit which restores and re-establishes what had been removed from its proper place or space.
There is another type of attraction which is not perceived by the senses. This is the case of a magnet attracting iron. The cause of this cannot be attributed to a vacuum or to any such thing, but only to the outflow of atoms or parts, which occurs in all bodies. For when atoms of one type move towards and mutually encounter other atoms of a similar type or of a congenial and compatible nature, the bodies develop such an attraction and impulse for each other that the overpowered body moves towards the whole of the stronger body. For since all the parts experience this attraction, then so must the whole body also be attracted.
This is illustrated for the senses in the case of two burning lamps. When the lower one is extinguished, fumes and spirits flow up from it (these are
? ? ?
On magic
? well disposed to become flames or to be nourishment for fire), and the upper flame then rapidly descends to re-ignite the lower lamp. This is also found in the small flames of torches. To avoid being extinguished by mois- ture absorbed from the environment, they clearly are attracted to flamma- ble materials located nearby, and they clearly are attracted to a larger flame either in a straight line or indirectly by jumping or leaping across.
And thus it happens that the overpowered parts of iron are attracted by some type of power or quality (although not all activities in such natural, composite things are due to active and passive qualities); even though this happens sometimes by necessity, that is not the rule. The fact that this attraction is caused by the outflow of parts from such bodies also indicates that when a magnet or amber is rubbed, it attracts iron or straw much more strongly. For the heat causes more parts to be emitted, since it opens the pores and rarefies the body.
From this, it is clear that a similar explanation is to be given of how rhubarb attracts choleric humours from the extremities and surface parts of animals to their intestines, when it has sufficient power, that is, when it is not so strong as to be expelled by nature before it acts, nor so weak as only to move the humours and not attract them.
In magnets and similar things, the attractive force and power is not due to an active or passive quality, in the commonly-used sense of a kind of action or passion, as is found in the four elements. A sign of this is that when a piece of iron touches a magnet, it acquires the same power of attracting other pieces of iron. This could not happen if this were due to an elemen- tary quality. For when heat and coldness are accidentally present in a sub- ject, they quickly disappear when the source of heat is removed. Therefore, one must explain this in terms of the emission of parts or of a spiritual sub- stance which flows from the magnet into the iron. It is difficult to imagine any other or even a similar cause of these effects. Also from this perspec- tive, which is fully self-consistent, it is easy to evaluate the various fantasies and dreams which others have mentioned as the causes of this attraction.
This same explanation and cause accounts for the fact that diamonds are said to block such an attraction, and similar types of explanation account for various other things. For the outflow of a specific power can weaken another power, or actuate and sharpen certain other powers. Thus, it is said that diamonds confer magnanimity on those who wear them.
It is not easy to explain why magnetic attraction occurs at the pole of the earth, especially if what some say is not true, namely, that in that region
? ? ?
On magic
? there are many large magnetic mountains. This is very hard to believe, but let us assume it anyhow. Then we ask why this attraction occurs at all dis- tances from that place. We are not speaking here of active but of passive magnetic attraction. I have not yet experienced whether a magnet attracts another magnet. If there are such mountains, and if they exert their power at such great distances, then since they attract a compass needle at the equator and in the tropics, in our region of the earth they would attract men wearing armour. But this is completely ridiculous. If we grant that a mag- net attracts iron when there is nothing except air between them, and if the attraction occurs in a straight line from our region of the earth to those places across the northern sea where the magnetic mountains and cliffs are located, then a large arc of the earth lies in between. Therefore, the magnet would attract iron (or another magnet, if that could happen for a similar reason), if our magnet is located at A and the mountains are at D. The
attraction must then occur at B or C, and thus, it crosses either through the large straight line distance AB or AC as indicated, or through the large arc of the earth AB and AC as indicated.
It is clear that this common and well-known argument falls apart for many reasons. To these objections we add that these magnetic mountains do not have the power to attract a magnet because they are similar to each other; if that were the case, we would see a very small magnet attracted by a very large one. Thus, we cannot appeal to attraction as the cause of this effect, because, as was said, it is iron which is attracted, while the magnet
? ? ? ?
On magic
? rather moves away, for this mineral and iron, which are derived from the earth and are cold like the earth, are contraries by nature. What happens to them is the opposite of what happens to almost all flowers which turn towards the sun and follow the path of the sun, as can be seen, for the sake of this argument, not only in heliotropes, but also in the narcissus, the crocus and in innumerable other flowers. Therefore, we can safely say that these things, which are hostile to the sun and to heat, turn towards and hurry towards those places which are the most removed from the sun and heat.
Epilogue on the motions which occur in things
Thus, we find that local motion occurs in many ways. First is the motion which constitutes and preserves life (i. e. , the circular motion of things in their own place due to the soul, or native spirit, as was said above); second is the fleeing of a contrary; third is the acquisition of something helpful or good; fourth is the expulsion and rejection by a contrary impulse; fifth is the violent attraction by a contrary which needs or seeks some material to convert into itself; sixth is an animal choice in accordance with the ten- dency of a natural power; the last is a violent motion, which either impedes or stops natural powers by some device or desire, or which is due to nature itself which, while it is strong enough to move something in one direction, blocks or impedes another motion of a lesser power, as happens almost everywhere. For example, a natural flow of water in one direction is stopped by another flow of water, as occurs when rivers flowing into the ocean are resisted by the flow of the sea and are turned back for many miles towards their sources.
On the bonding of spirits
As was said above, some spirits reside in more subtle matter, others in more dense matter; some reside in composite bodies, others in more simple bod- ies; some in observable bodies, others in unobservable bodies. As a result, the operations of the soul are sometimes easier, sometimes more difficult, sometimes weaker, sometimes well adapted, sometimes impossible. Some spirits operate within one genus, others act more efficaciously in another genus. Thus, humans possess certain operations and actions and desires not found in demons, and vice versa.

? usually mentioned fields of mathematics, i. e. , geometry, arithmetic, astron- omy, optics, music, etc. , but rather by its likeness and relationship to these disciplines. It is similar to geometry in that it uses figures and symbols, to music in its chants, to arithmetic in its numbers and manipulations, to astronomy in its concerns for times and motions, and to optics in making observations. In general, it is similar to mathematics as a whole, either because it mediates between divine and natural actions, or because it shares or lacks something of both. For some things are intermediates because they participate in both extremes, others because they are excluded from both extremes, in which case they should not be called intermediates but a third species which is not between the other two but outside of them. From what has been said, it is clear how divine and physical magic differ from the third type.
To turn now to the particulars, magicians take it as axiomatic that, in all the panorama before our eyes, God acts on the gods; the gods act on the celestial or astral bodies, which are divine bodies; these act on the spirits who reside in and control the stars, one of which is the earth; the spirits act on the elements, the elements on the compounds, the compounds on the senses; the senses on the soul, and the soul on the whole animal. This is the descending scale.
By contrast, the ascending scale is from the animal through the soul to the senses, through the senses to compounds, through compounds to the elements, through these to spirits, through the spirits in the elements to those in the stars, through these to the incorporeal gods who have an ethereal substance or body, through them to the soul of the world or the spirit of the universe; and through that to the contemplation of the one, most simple, best, greatest, incorporeal, absolute and self-sufficient being.
Thus, there is a descent from God through the world to animals, and an ascent from animals through the world to God. He is the highest point of the scale, pure act and active power, the purest light. At the bottom of the scale is matter, darkness and pure passive potency, which can become all things from the bottom, just as He can make all things from the top. Between the highest and lowest levels, there are intermediaries, the higher of which have a greater share of light and action and active power, while the lower levels have a greater share of darkness, potency and passive power.
As a result, all light in lower things, which comes to them from above, is more powerful in higher things. And also, all darkness in higher things is stronger in lower things. But the nature and power of light and darkness
? ? ?
On magic
? are not equal. For light diffuses and penetrates through the lowest and deepest darkness, but darkness does not touch the purest sphere of light. Thus, light penetrates and conquers darkness and overflows to infinity, while darkness does not penetrate or overwhelm or equal the light, but rather is very weak compared to light.
Parallel to the three types of magic mentioned above, there are three different worlds to be distinguished: the archetypal, the physical and the rational. Friendship and strife are located in the archetypal world, fire and water in the physical world, and light and darkness in the mathematical world. Light and darkness descend from fire and water, which in turn descend from peace and strife. Thus, the first world produces the third world through the second, and the third world is reflected in the first through the second.
Leaving aside those principles of magic which play on the superstitious and which, whatever they be, are unworthy of the general public, we will direct our thoughts only to those things which contribute to wisdom and which can satisfy better minds. Nevertheless, no type of magic is unwor- thy of notice and examination, because every science deals with the good, as Aristotle says in the introduction to his De anima,4 and as Thomas and other more contemplative theologians agree. Nevertheless, all this should be kept far away from profane and wicked people and from the multitudes. For nothing is so good that impious and sacrilegious and wicked people cannot contort its proper benefit into evil.
In general, there are two types of efficient cause: nature and the will. The will is threefold: human, spiritual and divine. Nature, as used here, is twofold: intrinsic and extrinsic. Furthermore, intrinsic nature is of two kinds: matter or the subject, and form with its natural power. Extrinsic nature is also of two kinds: the first, which is preferably called an image of nature, is a trace and shadow or light which remains in a thing within its body, like light and heat in the sun and in other hot bodies; the second emanates and radiates from a subject, like light, which flows from the sun and is found in illuminated things, and like heat, which resides with light in the sun and is also found in heated bodies.
By examining the number of these causes, we can descend to the differentiation of powers or of effects produced by the first cause through the intermediate causes down to the closest and lowest ones, by restricting the universal cause, which, itself, does not attend to any one available
4 Aristotle, De anima, ? , ? (? ? ? . a. ? -? ). ? ? ?
? On magic
? subject rather than another. For, although this cause and its causal power always remain immutably the same, it produces contrary (and not just different) effects in different subjects with the help of different types of matter. As a result, there need be only one such simple, principal efficient cause, like there is only one sun, one heat and one light, which by turning forward or backward, by approaching and receding, mediately and imme- diately causes the winter, the summer, and their different and contrary weather, and the ordering of the seasons.
Matter is also derived from this same cause, if we wish to believe those who think that the four commonly mentioned elements change into each other. The originator of this view was Plato, who sometimes says that all things were produced from one matter and one efficient cause. But what- ever may have been the method of production used by the first universal cause, and whether one assumes only one or many material principles, any human or spiritual secondary cause must recognize that, because of the great multitude and variety of producing species, there are many types of matter having act or form, through which a subject is able to influence things outside of itself.
In regard to the powers or forms or accidents which are transmitted from subject to subject, some are observable, for example, those that belong to the genus of active and passive qualities, and the things that immediately follow from them, like heating and cooling, wetting and drying, softening and hardening, attracting and repelling. Others are more hidden because their effects are also obscure, for example, to be happy or sad, to experience desire or aversion, and fear or boldness. These are said to be caused by external impressions acting on the cognitive power in humans and on the estimative power in animals. Thus, when a child or infant sees a snake, or when a sheep sees a wolf, it conceives an image, without any other experience, of hostility and of fear of its own death or destruction.
The explanation of this is to be found in the internal sense, which is, indeed, moved by the external impressions, although indirectly. For nature gives not only existence to each species, but also the desire in each individ- ual to preserve itself in its present state. Thus, it implants in each thing an internal spirit, or sense, if you prefer that word, by which as from an inter- nal dictate it recognizes and avoids great dangers. This can be seen not only in the examples given above, but also in all things in which, even if they seem to be defective or dead, there still resides a spirit striving with all its power to conserve the present condition. This happens in falling drops
? ? ?
On magic
? of liquids which form a sphere to avoid disintegration, and also in falling bodies which are attracted to a centre and tend to gather their parts into a sphere lest they break up and disperse. This is also found in pieces of straw or wood thrown on a fire, and in thin tissues and membranes, which recoil to avoid, somehow, their own destruction.
This particular sense is located in all things and is a form of life, although, in accordance with the common custom, we do not call it an ani- mal, which refers to a specific soul, because these components cannot be called animals. Nevertheless, in the order of the universe, one can recog- nize that there is one spirit which is diffused everywhere and in all things, and that everywhere and in all things there is a sense of grasping things which perceives such effects and passions.
Just as our soul produces, originally and in a general way, all vital activities from the whole body, and even though the whole soul is in the whole body and in each of its parts, nevertheless, it does not produce every action in the whole body or in each of its parts. Rather, it causes vision in the eyes, hear- ing in the ears and taste in the mouth (but if the eye were located in any other place, we would see in that place, and if the organs of all the senses were located in any one place, we would perceive everything in that place). In the same way, the soul of the world is in the whole world, and is every- where so adapted to matter that, at each place, it produces the proper sub- ject and causes the proper actions. Therefore, although the world soul is located equally everywhere, it does not act equally everywhere, because matter is not arranged to be equally disposed to it everywhere. Thus, the whole soul is in the whole body, in the bones and in the veins and in the heart; it is no more present in one part than in another, and it is no less pre- sent in one part than in the whole, nor in the whole less than in one part. Rather, it causes a nerve to be a nerve in one place, a vein to be a vein else- where, blood to be blood, and the heart to be the heart elsewhere. And as these parts happen to be changed, either by an extrinsic efficient cause or by an intrinsic passive principle, then the activity of the soul must also change.
This is the most important and most fundamental of all the principles which provide an explanation of the marvels found in nature; namely, that because of the active principle and spirit or universal soul, nothing is so incomplete, defective or imperfect, or, according to common opinion, so completely insignificant that it could not become the source of great events. Indeed, on the contrary, a very large disintegration into such components must occur for an almost completely new world to be generated from them.

On magic
? While bronze is more similar to gold and is closer to the distinctive prop- erties of gold than are the ashes of bronze, still, in a transmutation, these ashes of bronze are closer to the form of gold than is bronze. Likewise, we see that all seeds, which are oriented to producing a particular species, hap- pen to be rather alike as though they were of the same, and not different, species, since they are similar and distinctive and related. He who believes otherwise is like someone who thinks that an ape can be changed into a human more easily than the seed, implanted in a woman, which previously was food and bread.
Nevertheless, in every production, there must be present a similarity and a form of the same species. Just as a house or a garment results from a model in the maker's mind in the case of artefacts, likewise, in the productions of nature, a species of things is generated and defined by the exemplar, which is distinctive of the matter which generates the form. For example, we see the same types of food, and the same heavens, water and houses reproduced in substance: a dog into a dog, a human into a human, a cat into a cat. And a dog generates the same species of dog, and a human the same species of human.
From this, it is clear that the entire cause of the differences is due to an idea, which is generally present everywhere in nature, and which is later limited to this or that species, depending on whether one or other species resembles the idea more. As a result, any magician who wishes to carry out his work in accordance with nature must especially understand this ideal principle and how it applies specifically to species, numerically to numbers and individually to individuals. From this, he formulates an image and the proportions of the matter so formed, and with good reasons reinforces the result with the wisdom and power of his magic. Many also bring about cures and injuries by connecting symbols with particular components or by appealing to those who communicate with or take part in curing or destructive forces. In this way, the work of magic is restricted and applied to a particular individual.
Leaving aside other arguments, it is clear from these experiences that every soul and spirit has some degree of continuity with the universal spirit, which is recognized to be located not only where the individual soul lives and perceives, but also to be spread out everywhere in its essence and substance, as many Platonists and Pythagoreans have taught. As a result, vision grasps the most distant things immediately and without motion, and, indeed, the eye, or some part thereof, extends immediately to the stars or immediately from the stars to the eye.
? ? ?
On magic
? Furthermore, the soul, in its power, is present in some way in the entire universe, because it apprehends substances which are not included in the body in which it lives, although they are related to it. Thus, if certain impediments are excluded, the soul has an immediate and sudden presence with the most distant things, which are not joined to it by any motion, which nobody would deny, but rather are directly present in a certain sense.
Experience teaches this also in the case of those whose nose has been cut off; if they arrange to grow a new nose for themselves from the flesh of some other animal, and if that animal whose flesh was used dies, then as the body of that animal rots, so does the borrowed nose. From this, it is clear that the soul diffuses outside of the body in every aspect of its nature. 5 It also follows that the soul knows not only the members of its own body, but also everything for which it has any use, participation, or interaction.
There is no value in the stupid argument, advanced by those who lack true philosophical principles, that a thing which is touched by something else does not itself perceive that. Indeed, in one sense, this is true if we are distinguishing between species or individuals, but it is false if we are dis- tinguishing one bodily part from another. For example, if someone injures a finger or pricks one part of the body with a pin, the whole body is imme- diately disturbed everywhere and not just in that part where the injury occurred.
And so, since every soul is in contact with the universal soul, it is not pos- sible to find in this case the same effects which occur in bodies which do not mutually penetrate into each other. Rather, for spiritual substances, a different comparison is needed. For instance, if innumerable lamps are lit, they all act together as though they were one light, and no one light impedes or reflects or excludes another. The same thing happens when many voices are diffused through the same air, or if many visible rays, to use the common saying, spread out to reveal the same visible whole. All these rays pass through the same medium, and while some move in straight lines and others obliquely, they do not interfere with each other. In the same way, innumerable spirits and souls, when spread out through the same space, do not interfere with each other such that the diffusion of one would affect the diffusion of an infinity of others.
This power belongs not only to the soul but also to certain accidents, like sound, light and vision. The reason is that the whole soul is located in the whole body and in every part of the body, and that the whole soul
5 This is Thesis ? ? in Bruno's Theses de magia. See his Opera latine conscripta, ? ? ? , ? ? ? . ? ? ?
? On magic
? apprehends all things, however diverse and distant, which are around it outside of its body. This is a sign that the soul is not included in the body as its first act and substance,6 and that it is not circumscribed by the body. Rather, in itself and by itself, it should be understood only as a second act. This principle is the cause of innumerable marvellous effects, although its nature and power need to be investigated. This soul and divine substance cannot be inferior to the accidents which issue from it as its effects, traces and shadows. I declare that if the voice operates outside the body which produces it, and enters as a whole into innumerable ears on all sides, then why cannot the whole substance, which produces the voice which is tied to certain organs of the body, be located in different places and parts?
Furthermore, it must be noted that occult intelligence is not heard or understood in all languages. For the voices spoken by humans are not heard in the same way as the voices of nature. As a result, poetry, especially of the tragic type (as Plotinus says), has a very great effect on the wavering thoughts of the soul.
Likewise, not all writings have the same impact as those markings which signify things by the particular way in which they are drawn and config- ured. Thus, when certain symbols are arranged in different ways, they rep- resent different things: in a circle, the attraction of love; when opposed, the descent into hate and separation; when brief, defective and broken, they point to destruction; when knotted, to bondage; when strung out, to dis- solution. Furthermore, these symbols do not have a fixed and definite form. Rather, each person, by the dictate of his own inspiration or by the impulse of his own spirit, determines his own reactions of desiring or rejecting something. And thus, he characterizes for himself each symbol according to his own impulse, and as the divine spirit personally exerts cer- tain powers which are not expressed in any explicit language, speech, or writing.
Such were the figures, so well designed by the Egyptians, which are called hieroglyphics or sacred symbols. These were specific images selected from natural objects and their parts to designate individual things. The Egyptians used these symbols and sounds to converse with the gods to accomplish extraordinary results. Later, when Theuth,7 or someone else, invented the letters of the type we use today for other purposes, this
6 This sentence is an explicit rejection of Aristotle's definition of the soul in De anima, ? ? , ? (? ? ? . a. ? ? -? ? ).
7 See Plato, Phaedrus, ? ? ? c-e, for an account of this legend about the origins of written language.
? ? ? ?
On magic
? resulted in a tremendous loss, first of memory, and then of divine science and magic.
Like those Egyptians, magicians today formulate images, written sym- bols and ceremonies, which consist of certain actions and cults, and through which they express and make known their wishes with certain sig- nals. This is the language of the gods which, unlike all other languages which change a thousand times every day, remains always the same, just as natural species remain always the same.
For the same reasons, the spirits speak to us through visions and dreams, but we claim that these are enigmas, because of our unfamiliarity and igno- rance and weak capacities, even though they are the very same sounds and very same expressions used for representable things. Just as these sounds elude our grasp, likewise our Latin, Greek and Italian sounds sometimes fail to be heard and understood by the higher and eternal spirits, which differ from us in species. Thus, it is no easier for us to be able to commu- nicate with the spirits than it is for an eagle to converse with a human. Just as there can be conversation and agreement only by means of gestures between two groups of humans who do not share a common language, like- wise, there can be communication between us and certain types of spirits only by the use of certain signs, signals, figures, symbols, gestures and other ceremonies. The magician, especially when using the kind of magic which is called 'theurgy', can hardly accomplish anything without such sounds and symbols.
On the communion and interaction of things
From the above, one can understand and explain how interaction occurs not only between things which, to the senses, are near each other, but also between things which are far apart. For, as was said above, things are united by a universal spirit which is present as a whole in the whole world and in each of its parts. As a result, just as different lights come together in the same space, likewise, the souls of the universe, whether they be finite or infinite in number, interact in their powers and activities. However, this does not happen to bodies, because they are limited and circumscribed by their surfaces and surroundings, and because they are composed of innu- merably different parts in different bodies and places (if we can speak of place rather than space. ) Therefore, no body can act on another body, and no matter on other matter, nor can the material parts of one body act on the
? ? ?
On magic
? parts of another body, but rather, all action comes from quality and form and ultimately from soul. The soul first changes the dispositions, and then the dispositions change bodies. Thus, bodies act on distant bodies, on nearby ones and on their own parts, by means of a certain harmony, joining and union which comes from form. For, since every body is governed by a soul or a spirit which connects its parts, and since one soul acts on another nearby soul in any direction and wherever it is, it follows necessarily that a soul moves that body, wherever it is, because it is controlled by, and subor- dinate to, that soul. Whoever is aware of this indissoluble continuity of the soul and its necessary connection to a body will possess an important principle both to control natural things and to understand them better.
From this follows clearly the reason why a void, i. e. , a space empty of any body, does not exist. For no body can leave one place without being replaced by another. During life, the soul does leave its own body, but it cannot leave the universal body, nor can it be abandoned by the universal body, if you prefer to state it that way. For, when it leaves one simple or complex body, it moves into another simple or complex body, or from one body left behind, it goes to and enters into another. Thus, it has an indis- soluble connection with universal matter. And since its own nature is to be a continuous whole everywhere, we realize that it exists together with a material body everywhere. From this, we conclude that the void does not exist in the sense of a space with no matter in it, but rather a void is a space in which different bodies move and succeed each other. It also follows that the motion of the parts of one body towards the parts of another body is continuous. Motion occurs through a continuous space which is not inter- rupted by any void located between full spaces, unless we wish to say that a space in which there is no sensible body is a void.
A continuous body is an unobservable body, that is, an airy or ethereal spirit. It is very active and very powerful and very similar to the soul, and it is quite different from the dense sluggishness found in observable, com- posite substances. The above mentioned powers of unobservable spiritual bodies are the source of all the powers in observable bodies themselves. Indications of this are the airy spirit which agitates and embroils all the seas, and the invincible force of the winds which, even when they are rather calm and quiet, disturb the earth, break trees and destroy houses. Lucretius put it well when he said that it is this spiritual body which performs all actions in observable things. 8 Many philosophers have thought that this
8 Lucretius, De rerum natura, ? , ? ? ? ff. ? ? ?
? On magic
? spiritual body is the same thing as the soul, and the poet has said that this air 'has the power of fire and the soul'. 9
Furthermore, fire, which does not consist of dense matter like coal, which is rather an ignited body, is to be understood as different from air only accidentally. For true fire is, indeed, a spirit, which is sluggish when it is located in an ignited body, but it is lively when it is outside of an ignited body, and it is a form of motion in a flame or in some intermediate state.
This spirit, acting in different ways, forms different bodies and animals. And although not all composite bodies are animals, it must be noted that all animals have a soul which is of the same type in all the members of one genus. However, that soul is not actuated in one and the same way because of differences in the dispositions of matter and in objective ideals. From this, it follows that, since there are different and contrary forms, there are also differences and reasons why some animals congregate with each other, being attracted and impelled to various places, while others flee from or pursue each other. All of this is due to the way they are structured.
All things desire to preserve their own existence, and thus they forcibly and unwillingly resist separation from the place where they exist and per- severe. This force is so strong that the sun or fire attracts water to itself through airy space only after it has first made the water like air, that is, by converting it into a vapour. After that has happened, then the substance which was water is attracted willingly, and by means of the same impulse of attraction, it tries to adapt itself so that it slowly becomes more and more like fire, and finally, it becomes fire itself. On the other hand, that most sub- tle body which is contained in the spirit in the form of fire changes back into water by the opposite sequence as it congeals and thickens.
Therefore, the same substance and matter changes from water to vapour, from vapour to air, and from air to the thinnest and most penetrating ethe- real body. The latter has been called a 'spirit' by the Egyptians, Moses and Dionysius of Apollonia, although they differ because Moses did not distinguish spirit from soul (according to his words; I do not judge his meaning), which the others did. The other substance [earth] is dry and composed of atoms, which are very solid and indissoluble bodies. In them- selves, they are neither continuous nor divisible and, thus, cannot be changed into any other body. And the substance of water or spirit or air, which is the same, never changes into the substance of atoms or dry earth, nor vice versa.
9 Virgil, Aeneid, ? ? ? ? , ? ? ? . ? ? ?
? On magic
? This philosophy is supreme, divine and true, since it is quite in agree- ment with nature by positing the following principles of reality: first, water or the abyss or the Styx; second, dryness or atoms or earth (I am not speak- ing of the terrestrial globe); third, spirit or air or soul; fourth, light. These are so different from each other that one cannot be transformed into the nature of another, although they do come together and associate, sometimes more or less, sometimes all or some of them.
On the double motion of things and on attraction
There are two kinds of motion, natural and preternatural. Natural motion comes from an intrinsic principle, while preternatural motion is from an extrinsic principle; natural motion is in harmony with the nature, struc- ture and generation of things, preternatural motion is not. The latter is twofold: violent, which is against nature, and ordered or structured, which is not contrary to nature. What is commonly called natural motion is found in all genera or in all the categories, leaving out the distinction between motion and mutation. 10
For now, we omit all the other classes of motion and their species and consider only natural motion in place. One type of this is possessed by nat- ural things and does not move a thing away from it own proper place; this is circular motion, or a version thereof. The other type is straight line motion, which is not naturally possessed by natural things. For example, air moves in a straight line to fill a void. A stone moves through air, and a body which is heavier than water moves through water, in a straight line in order to occupy the place in which it either is at rest or moves naturally. And as much as it can, a contrary flees from its contrary in a straight line, for example, fumes, vapour and water from fire (for it goes faster to a greater distance through a straight line). Likewise, similar and agreeable things tend towards each other in a straight line, for example, straw to amber, and iron to a magnet, so that they can rest together or move better and more easily.
There is also a third type of local motion, which is an inflow and an outflow found in all natural things when any of their parts are ejected in various ways and in every direction. For now, we will call this 'spher- ical' motion. For it does not occur either in a straight line, or to or from
? 10 This is an Aristotelian distinction in which 'motion' refers to changes in quality, quantity and place, while 'mutation' refers to changes in substance or essence.
? ? ?
On magic
? or around a centre. Rather, it occurs along an infinity of lines from the same centre, for while some parts of the body are ejected and emitted outward from the body's convex surface and perimeter, others are recipro- cally received and absorbed. Bodies grow and are invigorated when the inflow of beneficial things is greater than their outflow, and they age and weaken and become sluggish when the inflow of extraneous things is greater than the outflow of natural things. This is the reason why cor- ruption and change occur in things, including all changes or alterations and disintegrations . . . 11
There is no controversy over the evidence for the first two types of motion, and, as a result, the understanding and classifications of them are well known. But a more careful consideration of the third type will be found to be not only needed and helpful, but also necessary. The situation is especially clear in things which have very strong sensible qualities. For instance, fire warms in every direction and not just on one side or another. For, as soon as it is lighted, it sends out its light and flames in every direc- tion. Likewise, a sound and a voice penetrate equally in all directions, if they occur in a medium which is open on all sides. In the same way, it is quite clear that the sense of smell is activated by the continuous emission of small parts from an odoriferous body. This could not happen unless that body's substance were to flow out and emit its parts in all directions. The same thing happens in the case of reflections and other such observable occurrences. Innumerable other accidental things are caused by certain parts flowing out, and sometimes these parts travel an enormous distance from a very small observable source, as is clear when a small amount of something emits a smell for many years.
In addition to these observable qualities or powers which are emitted from bodies spherically, there are other, more spiritual and less heavy ones which act not only on the body and on the senses, but also on the interior spirit. The more powerful ones touch the powers of the soul and cause various effects and passions, as is commonly thought to be true of many stones, herbs and minerals. This is also clear in fantasies and in cases where the eye has actively or passively been hit. An example is the basilisk12 who, by looking at a man a long way off, can kill him with the sharpness of its vision.
? 11 There is a break in Bruno's text at this point.
12 The basilisk, also called a cockatrice, was a legendary monster resembling a lizard which was said to
have been hatched by a snake from a cock's egg. Its breath and glance were supposedly fatal.

On magic
? How a magnet attracts iron, coral attracts blood, etc.
What was said above explains why magnets naturally attract things. There are two kinds of attraction. The first occurs by agreement, as when parts move to their proper place and are oriented to that place, and when simi- lar and harmonious things attract each other. The second type occurs with- out agreement, as when contraries come together because the one which cannot escape is overwhelmed, as when moisture is attracted by fire. This is clear in the case of a burning object being held above a bowl containing water, where the water is sucked up by the heat and rises rapidly. The same thing happens when waterspouts and hurricanes occur at sea, with the result that sometimes even ships are thrown a great distance upwards by the waves.
Attraction occurs in three ways. The cause of the first type is clear to the senses, as is shown in the cases mentioned above. This also happens when the attraction and absorption of air attract objects contained in the air. This is, likewise, evident in pipes through which water is sucked, and thus rises to any level. This happens for the reason given. For if the air in the tube is attracted, and if there is no other air to take its place, then water or earth or something else will fill that space. If nothing can replace it, then the air would be held back and retained by the power of the vacuum, as is clear when an opening is obstructed by objects being sucked in and swallowed. Another example occurs when the tongue and lips are held together and their opening is very tightly compressed around the mediating air, and vice versa, when one sucks so that there is elicited from the mouth's pores a spirit which restores and re-establishes what had been removed from its proper place or space.
There is another type of attraction which is not perceived by the senses. This is the case of a magnet attracting iron. The cause of this cannot be attributed to a vacuum or to any such thing, but only to the outflow of atoms or parts, which occurs in all bodies. For when atoms of one type move towards and mutually encounter other atoms of a similar type or of a congenial and compatible nature, the bodies develop such an attraction and impulse for each other that the overpowered body moves towards the whole of the stronger body. For since all the parts experience this attraction, then so must the whole body also be attracted.
This is illustrated for the senses in the case of two burning lamps. When the lower one is extinguished, fumes and spirits flow up from it (these are
? ? ?
On magic
? well disposed to become flames or to be nourishment for fire), and the upper flame then rapidly descends to re-ignite the lower lamp. This is also found in the small flames of torches. To avoid being extinguished by mois- ture absorbed from the environment, they clearly are attracted to flamma- ble materials located nearby, and they clearly are attracted to a larger flame either in a straight line or indirectly by jumping or leaping across.
And thus it happens that the overpowered parts of iron are attracted by some type of power or quality (although not all activities in such natural, composite things are due to active and passive qualities); even though this happens sometimes by necessity, that is not the rule. The fact that this attraction is caused by the outflow of parts from such bodies also indicates that when a magnet or amber is rubbed, it attracts iron or straw much more strongly. For the heat causes more parts to be emitted, since it opens the pores and rarefies the body.
From this, it is clear that a similar explanation is to be given of how rhubarb attracts choleric humours from the extremities and surface parts of animals to their intestines, when it has sufficient power, that is, when it is not so strong as to be expelled by nature before it acts, nor so weak as only to move the humours and not attract them.
In magnets and similar things, the attractive force and power is not due to an active or passive quality, in the commonly-used sense of a kind of action or passion, as is found in the four elements. A sign of this is that when a piece of iron touches a magnet, it acquires the same power of attracting other pieces of iron. This could not happen if this were due to an elemen- tary quality. For when heat and coldness are accidentally present in a sub- ject, they quickly disappear when the source of heat is removed. Therefore, one must explain this in terms of the emission of parts or of a spiritual sub- stance which flows from the magnet into the iron. It is difficult to imagine any other or even a similar cause of these effects. Also from this perspec- tive, which is fully self-consistent, it is easy to evaluate the various fantasies and dreams which others have mentioned as the causes of this attraction.
This same explanation and cause accounts for the fact that diamonds are said to block such an attraction, and similar types of explanation account for various other things. For the outflow of a specific power can weaken another power, or actuate and sharpen certain other powers. Thus, it is said that diamonds confer magnanimity on those who wear them.
It is not easy to explain why magnetic attraction occurs at the pole of the earth, especially if what some say is not true, namely, that in that region
? ? ?
On magic
? there are many large magnetic mountains. This is very hard to believe, but let us assume it anyhow. Then we ask why this attraction occurs at all dis- tances from that place. We are not speaking here of active but of passive magnetic attraction. I have not yet experienced whether a magnet attracts another magnet. If there are such mountains, and if they exert their power at such great distances, then since they attract a compass needle at the equator and in the tropics, in our region of the earth they would attract men wearing armour. But this is completely ridiculous. If we grant that a mag- net attracts iron when there is nothing except air between them, and if the attraction occurs in a straight line from our region of the earth to those places across the northern sea where the magnetic mountains and cliffs are located, then a large arc of the earth lies in between. Therefore, the magnet would attract iron (or another magnet, if that could happen for a similar reason), if our magnet is located at A and the mountains are at D. The
attraction must then occur at B or C, and thus, it crosses either through the large straight line distance AB or AC as indicated, or through the large arc of the earth AB and AC as indicated.
It is clear that this common and well-known argument falls apart for many reasons. To these objections we add that these magnetic mountains do not have the power to attract a magnet because they are similar to each other; if that were the case, we would see a very small magnet attracted by a very large one. Thus, we cannot appeal to attraction as the cause of this effect, because, as was said, it is iron which is attracted, while the magnet
? ? ? ?
On magic
? rather moves away, for this mineral and iron, which are derived from the earth and are cold like the earth, are contraries by nature. What happens to them is the opposite of what happens to almost all flowers which turn towards the sun and follow the path of the sun, as can be seen, for the sake of this argument, not only in heliotropes, but also in the narcissus, the crocus and in innumerable other flowers. Therefore, we can safely say that these things, which are hostile to the sun and to heat, turn towards and hurry towards those places which are the most removed from the sun and heat.
Epilogue on the motions which occur in things
Thus, we find that local motion occurs in many ways. First is the motion which constitutes and preserves life (i. e. , the circular motion of things in their own place due to the soul, or native spirit, as was said above); second is the fleeing of a contrary; third is the acquisition of something helpful or good; fourth is the expulsion and rejection by a contrary impulse; fifth is the violent attraction by a contrary which needs or seeks some material to convert into itself; sixth is an animal choice in accordance with the ten- dency of a natural power; the last is a violent motion, which either impedes or stops natural powers by some device or desire, or which is due to nature itself which, while it is strong enough to move something in one direction, blocks or impedes another motion of a lesser power, as happens almost everywhere. For example, a natural flow of water in one direction is stopped by another flow of water, as occurs when rivers flowing into the ocean are resisted by the flow of the sea and are turned back for many miles towards their sources.
On the bonding of spirits
As was said above, some spirits reside in more subtle matter, others in more dense matter; some reside in composite bodies, others in more simple bod- ies; some in observable bodies, others in unobservable bodies. As a result, the operations of the soul are sometimes easier, sometimes more difficult, sometimes weaker, sometimes well adapted, sometimes impossible. Some spirits operate within one genus, others act more efficaciously in another genus. Thus, humans possess certain operations and actions and desires not found in demons, and vice versa.
