The Thomist system is a grandiose attempt to derive this justification of revelation from metaphysics, while that of Duns Scotus is an almost desperate
one.
At any rate, the first point I would ask you to note14 is that meta-
physical systems in the precise sense are doctrines according to which concepts form a kind of objective, constitutive support on which. what is naively called 'the objective world', that is, scattered, indi- vidual, existing things, is founded and finally depends. You may recall that I pointed out earlier in today's lecture that the question whether concepts are real or are merely signs, that is, the dispute
between nominalism and realism, is itself carried on within meta- physical enquiry - just as, originally, the realists and the nominalists were not opposed schools of metaphysicians and anti-metaphysicians respectively. Rather, these two schools - both in Islam and in medi- eval philosophy - were schools which arose and fought each other within metaphysical thinking. This reveals something which is im- portant if you are to avoid confusion in thinking about the concept of metaphysics. This concept has undergone a certain formalization which can also be seen as a part of its disintegration, in that the mere treatment of metaphysical questions - regardless of the outcome - is
? LECTURE ONE 9
? ? noW treated as metaphysics, and not just positive teachings about concepts as entities existing in themselves. Both things, therefore, the doctrine of the 'back-world' and the doctrine which repudiates this
back-world, would fall equally, and dubiously, within the field of metaphysical problems, according to this formalized or generalized concept. I say dubiously because there is a temptation here to draw a false conclusion which is constantly encountered in the field of vulgar apologetics. Whether one is for metaphysics or against metaphysics, both positions are metaphysical, both depend on ultimate positions about which it is not possible to argue, whereas the nature and opera- tion of concepts lie precisely in the fact that it is entirely possible to argue about them, and that, in general, if the anti-metaphysical posi- tion is subsumed under the concept of metaphysics, it is deprived of its critical edge, its polemical or dialectical potency. Thus, one speaks formally, for example, of metaphysical materialism (in contradistinc- tion to historical materialism), in which matter is designated as the ultimate ground of being, as the truly existent, as was once the case in the thought of Leucippus and Democritus. You can observe sim- ilar things in present-day theology, where, if anything is said about the name of God and His existence or non-existence, there is much rejoicing over the fact that God is mentioned at all, regardless of whether the speaker is 'for' or 'against' God. This, I would think, is enough to indicate that the present time, to put it cautiously, is un- likely to be the most propitious for the building of cathedrals. On the other hand, it is the case - one should add for the sake of justice - that in the thought of such early so-called anti-metaphysicians and materialists as Leucippus and Democritus, the structure of the meta- physical, of the absolute and final ground of explanation, is neverthe-
less preserved within their materialistic thought. If one calls these materialists metaphysical materialists, because matter for them is the ultimate ground of being, one does not entirely miss the mark. But this designation already contains a critical moment with regard to these early philosophers, a moment which led in the course of further reflection to a critique of what they taught.

The usual definition as, for example, the ultimate ground or cause of existing things; according to this, with the 'scientification' of
philosophy, metaphysics is supposed to be the fundamental science. Metaphysics seen accordingly as the doctrine of primary being

While I can mention subjects of metaphysics, such as being, ground of being, nothingness, God, freedom, immortality, becoming, truth, spirit, their full concept - like any strong concept - cannot be given in a verbal definition but only presented through a concrete treat- ment of the constellation of problems which forms the concept of metaphysics. In the second part of the lecture I shall give you models of these. 1
Decisive for an understanding ofphilosophical concepts - the his- tory of terminology.
The concept of metaphysics goes back to Aristotle, and specifically to the arrangement of the corpus Aristotelicum by Andronicus of Rhodes, 50-60 Be, in the first century before Christ, in which the main work of Aristotle devoted to that area, f1-ETd Td cpvatKa, was
placed after the Physics. Insertion 2 a
[Insertion 2 a:} as early as the Neo-Platonists this name, with its tech- nical implications for editing, was interpreted in terms of content: f1-ETd Td cpvatKa = that which goes beyond nature, or, precisely, what is 'behind nature' as its cause. {End of insertion}
? ? The term therefore arose from a principle ofliterary arrangement; a name for the subject was lacking because this subject was not a thing among things.

? ? [Ins. 3] traditional subdivision of metaphysics:
(1) Ontology = theory of Being and of existing things (2) The
nature of the world (cosmology) (3) of human beings (philosophical anthropology) (4) Existence and nature of the divinity (theology). Echoes of this in Kant, whose themes were prescribed by precisely what he criticized. This is good in that he does not think indiscrim- inately, and bad through its inhomogeneity with regard to his own nominalist assumptions.
Distinction between speculative and inductive metaphysics. All these are specifically dogmatic categories, relating to a prescribed and positively teachable area ofsubject matter, i. e. they aim at a merging oftheology and metaphysics. But as the subject matter is itselfprob-
lematic and no such doctrine can be advocated, I mention these categories, the pedantry of which makes a mockery of the subject, so that you are aware of them, without going into them further.
A similarly traditional distinction is drawn between deductive and inductive metaphysics (likewise not without hints from Aristotle)
Inductive metaphysics an artificially devised auxiliary concept intended to prop up a collapsed structure by adapting it to the very thing which has disintegrated it. Like relatively increasing misery2
Inductive = empirical = scientific.
Experience is therefore to be used to justify what transcends it. Heidegger's approach ofanalysing Dasein to gain access to ontology has similarities.
Something as apparently open to experience as Dasein, i. e. essen- tially the experience of the individual subject of himself, is supposed to give insight into the nature of being, despite the limits and ran- domness of this experience. Of course, this presupposes the meta-
physical privilege of the human being, who defines himself in calling Dasein the antic which at the same time is ontological, and is there-
fore
the contradiction in the way customary in science.
There is, in fact, a concept of metaphysical experience - though
not one which can be grasped by the usual means of induction or with reference to a self-revealing ontology. Perhaps, to begin with, simply a reluctance to accept the accepted. E. g. 'Luderbach', dead animals. 4 Why is the bank called a bank? 5
In presenting some of my own reflections on metaphysics6 in the second half of the lecture series, I hope I shall be able to give you an idea ofwhat I call metaphysical experience. But I can say already that,

? ? I closed my last lecture by putting forward the thesis that, in a precise sense, metaphysics began with Aristotle. This is a rather shocking thesis, although the shock will be somewhat less severe if one reflects that Greek speculation has a long prehistory in which it largely eman- cipated itself from hylozoism, with its rather crude reflections on nature; here I shall mention only the names of Heraclitus, Parmenides
and above all, of course, Plato. If I now attempt to substantiate this thesis somewhat further, it is not in order to indulge in witty para- doxes, but because I believe it will enable me to say something not unimportant about the concept of metaphysics itself. You will recall the definitions of metaphysics I gave earlier; they were not really
definitions in the strict sense, but a series of thematic indications and propositions intended to show you roughly what the concerns of metaphysics are. Among these indications the question of true being, of the One, the essential, played a major part. The Platonic doctrine of Ideas does indeed have to do with these concepts, and I assume you are all more or less familiar with it. The Ideas - that is, hypostatized universal concepts, as they are commonly called - are regarded by Plato, in contrast to scattered multiplicity, as the true, the One, the essential and, above all, as the cause of all appearances. This definition - really a definition of metaphysics itself, which deals
with the causes of all things - was taken over in Aristotle's Meta- physics and elevated to the definition of metaphysical questions. 1 According to Plato, only the forms of things have true and original
being; and these forms - this is the subject of the famous dispute he
?
16 LECTURE FOUR
? ? had with Antisthenes2 - are not merely the abstract attributes of diverse individual things. They are themselves, both logically and genetically, what is primary in individual things. For this reason they are called El8o:; or i8Ea, as that which has being in itself and is open to 'seeing', as is implied in the parable of the cave. 3 Both words -
El8o:;, essence, and i8Ea, our word for idea - contain the stem t8, fl8, which relates to the visual, the optical, to seeing. To this extent, therefore, in terms of his themes, Plato could be regarded as the arch- metaphysician, the metaphysician per se, and perhaps he may indeed be counted as such. But in Plato - and this is the crucial point, which
brings us a good deal closer to the meaning of the term metaphysics - the world of the senses is described as that which is absolutely without being, although he was no more able than the Eleatics before him to sustain this position rigorously. For him, the world of appear-
ances really does not exist in any strong sense. And it can be said - if you will allow me to put it rather drastically, just to point out the main landmarks in this discussion - that Plato's philosophy is a syn- thesis of Eleatism - especially Parmenides - and Heraclitus. From Parmenides he took the doctrine of being as the One, the absolutely indivisible and imperishable, and from Heraclitus the doctrine of the absolute transitoriness of appearance, which exists in a state of con- stant flux and, moreover, is deceptive and unreliable, as is shown above all in Plato's relatively late dialogue Theaetetus. His funda- mental attitude, which has had a profound and lasting influence on later western philosophy and constantly re-emerges in different forms, lies in the emphasis on deception, on the illusoriness of sense data. Even in a philosopher as nominalist as John Locke, this thesis recurs in the distinction between the primary qualities which are attributes of things in themselves, and the merely subjective, secondary qualities. 4
No word is needed - although in the history of philosophy many have been used - to make one aware that this drastic separation of the idea from the world of the senses is very difficult to maintain. In Plato it implies the doctrine of the non-being of the sensible, of 11-? av. It can be convincingly demonstrated that the qualities appropriated by the Ideas, in becoming that which has being in itself, are in reality taken over more or less directly from the world of appearances, and that the absolute status of the Idea is attained, as it were, at the expense of the world of the senses from which it is derived. Plato himself was by no means consistent in this respect. For example, in describing the Idea as the cause of all being and of all existing things, and locating the Idea in a realm of absolute origins, as opposed to the realm of things which have originated in it, he implies that there must be something else, precisely that which has originated. Or take another

? ? very famous theorem of Plato's: the doctrine of I1-E{}EgL? , of the par- ticipation of the scattered things in the Idea to which they are subordinate. s This also presupposes something different from the Idea; if there were nothing which was different from the Idea, such a 'participation' in the Idea, such a I1-E{}EgL? , would not be possible. And in fact, the late Plato did extensively revise the strict version of the doctrine of Ideas, as it appears in what are called the classical, middle dialogues. I would mention here the very curious dialogue
Plato's late period, which has given rise to innumerable diffi- culties and bears the name Parmenides. Naturally, you should not confuse this with the Eleatic Parmenides, although he is the protagon- ist and victor in this dialogue. In it Plato puts forward what might be seen as the implicitly very dialectical thesis that, however little the Many amount to without the One - the Many refers to the scattered
things, as opposed to the one Idea under which each thing in a genus
is subsumed - however little this Many may be without the One, without its Idea, just as little is the One, the Idea, without the Many. 6 There is no doubt that in Plato's late period the existent asserts itself increasingly against the Idea, although, in the chronology of Plato's works which is now generally accepted, one of the dialogues in which the doctrine of Ideas is presented most bluntly and developed most ingeniously, the Phaedrus, is dated extremely late. (I personally, despite all the authority of classical philology, am disinclined to
trust the current chronology, not for philological reasons but for philosophical ones, based on the subject matter. ) This dating does, of course, make the development of Plato that I have referred to, towards what might be called a greater acknowledgement of the
empirical, somewhat precarious. However, despite the protests of dyed-in-the-wool Platonists, I should like to assume such a develop- ment, and I would also mention that in the Anglo-Saxon countries, where there is a very strong culture in the interpretation of classical
Greek texts, one not infrequently comes across the hypothesis that Plato as an old man was influenced retrospectively by his pupil Aristotle; or that, as a result of his political disappointments in his attempts to set up the world purely on the basis of the Idea, he was forced to give greater recognition to that which is, the scattered, the merely existent. If one reviews the development of the great classical work on politics, the Politeia, through the Statesman to the last work, the Laws, there is much evidence to suggest that that is the case. But I am only mentioning this to show you how complex these relation-
ships are. Incidentally, you would all do well, before embarking on these very complex problems that I can only sketch for you here, to look at Goethe's famous descriptions of the two philosophers, whom
from

? ? he saw as antithetical, Plato and Aristotle; he contrasted what today would be vulgarly called the idealist Plato to the realist Aristotle,
who, as Goethe put it, had his feet planted firmly on the earth. 7 After what I have just said, my assertion that metaphysics really began with Aristotle will be doubly shocking (I seem to be bent on shocking you) because the importance Plato seems to attach to the higher world, to transcendence, as against the world itself, appears to make him far more metaphysical than his pupil Aristotle. But I believe we have arrived here at the central, problematic point from which you will be best able to understand what metaphysics really means. For even if we concede that Plat08 gave much greater weight, nolens volens (or however it may be), to the world of f1-? DV, or non- being, to the world of sensible experience, than he should have done according to the strict doctrine of Ideas; and even if we concede further that this tendency in Plato grew stronger in the course of his
long life, one thing is quite definitely lacking in his work: reflection on how these two spheres - of direct experience and of the Idea, the concept, the One, or whatever you like to call it - are related to each other. It might be best to say that while the traditional problems of metaphysics present themselves in the structure of the Platonic doctrine of Ideas, they do so, as it were, objectively, without being reflected thematically in his philosophy. While it is true that the ten- sion between the sphere of transcendence and the sphere of that which is merely the case, between TO OV and Ta DVTa, is present in Plato's philosophy, because it is unavoidable, breaking through again and again, his philosophy is not constituted in such a way that this tension is central to his speculation. Now, what I should really like to make understandable to you is that the sphere of metaphysics in the
precise sense only comes into being where this tension is itself the subject of philosophy, where it comes within the purview of thought. It might be said, therefore, that metaphysics arises at the point where the empirical world is taken seriously, and where its relation to the supra-sensible world, which was hitherto taken for granted, is sub- jected to reflection.
It is possible to imagine the Platonic doctrine of Ideas, without doing it too much violence, as a secularization of theology. The Platonic Ideas have been called the gods turned into concepts, and one would scarcely disagree, just as the supreme Idea, the Idea of the Good or of Justice, TO ayat'f6v or ? oLKawavvYj, is frequently referred to in Plato as t'fE6<;, probably in direct continuation of a Socratic tradition. But the problem posed by this secularization is
that once the gods are turned into concepts, that is, entities of ap- pearance, their relationship to appearances becomes something quite
? LECTURE FOUR 19
? other than if the gods were simply located in the Beyond, on their Olympus. This problem emerges again and again in the epistemolo- gical and logical difficulties with which Plato has to contend. But, if I might put it thus, he was naively theological in failing to draw from the secularization of the gods into concepts, which he had brought about, the conclusion that the relation of the concept or the Idea to the world of appearances was thereby radically changed, and made problematic. One might define metaphysics as the product of a breach between essences - the gods secularized as ideas - and the phenom- enal world, a breach which is inevitable as soon as the gods become concepts and being becomes a relation to existing things; at the same time, however, these two moments cannot be naively related together or formulated concurrently. I believe this way of stating the matter may better define the locus of metaphysics in the history of philosophy, and thus define the essence of metaphysics as well (for I believe the essential is always historical), than would be possible in the relatively
superficial lectures one might give on the themes of metaphysics. Following from this definition one might say that metaphysics, because it attempts to regard the Ideas as something linked to the empirical world but endangered by advancing secularization, was itself threatened from the first in its own development. In this con-
nection it is certainly no accident that nominalism - the radically rationalistic view which denied any autonomous existence to ideas - based itself precisely on Aristotle, and did so twice over, both in Arabian philosophy and in scholasticism; although, as cannot be
emphasized too much, Aristotle himself, as you will find out, was anything but a nominalist. When Heidegger refers to metaphysics as a kind of rationalistic decline from the original understanding of
being in archaic philosophy,9 I cannot entirely disagree, from a strictly phenomenological viewpoint, with his characterization. On one hand metaphysics is always, if you will, rationalistic as a critique of a conception of true, essential being-in-itself which does not justify itself before reason; but, on the other, it is always also an attempt to
rescue something which the philosopher's genius feels to be fading
and vanishing. There is in fact no metaphysics, or very little, which is
not an attempt to save - and to save by means of concepts - what
appeared at the time to be threatened precisely by concepts, and was
in the process of being disintegrated, or corroded, to use the more
affective language of the ancient anti-Sophists. Metaphysics is thus,
one might say, something fundamentally modern - if you do not
restrict the concept of modernity to our world but extend it to in-
clude Greek history. And it is no accident that metaphysics re-emerges in the High Middle Ages, a period of urban bourgeois culture in

? ? which the naive immediacy of Christian faith was already breaking down; and then a second time in the broad movement of thought which is generally embraced by terms such as the Renaissance, the Reformation and humanism.
Aristotle, in the first truly metaphysical work of literature - the one which gave that branch of philosophy its name - criticizes the Platonic attempt to oppose essence to the world of the senses, as something separate and absolutely different from it.
Above all, he criticizes the Platonic hypostasis of universal concepts as a duplica- tion of the world. In this he makes a very strong and legitimate case, based on the argument that all the attributes of the Ideas are derived from the empirical world, on which they live, rather as the rulers lived on the work of their servants or slaves. At the same time, how- ever, he then seeks in his turn to extract an essential being from the sensible, empirical world, and thereby to save it; and it is precisely this twofold aim of criticism and rescue which constitutes the nature of metaphysics. The polarity between critical rationality, on the one
hand, and the pathos of rescue, on the other, points to the essence of traditional metaphysics, or at least has done so throughout its his- tory. Metaphysics can thus be defined as the exertion of thought to save what at the same time it destroys. That this formulation is ten- able, and not arbitrary, is indicated, I believe, by the fact that the very same structure which I have demonstrated to you in principle by the example of Aristotle's Metaphysics - or as a precondition of that work - is also characteristic of Kant's position with regard to
the problem of metaphysics. Although Kant, in upholding a blunt, unreconciled dualism, undoubtedly has more in common with the philosophical climate of Plato than of Aristotle - and the Critique of Pure Reason contains, in the introduction to the section on the Ideas, the finest pages ever written about Plato,10 pages I would most strongly urge all of you to read - it can be said that in this double intention of critique and rescue Kant was closer to Aristotle, whom he did not particularly like, than to Plato. ll If you will take this historical-philosophical interpretation on trust for the time being, you will perhaps understand why I consider it necessary, for a correct understanding of the concept of metaphysics, to begin with an over- view of the main theoretical motifs of Aristotle's work. This does require you, however, to take some account of his historical position, for only this will allow you to picture more concretely what I have in mind.
This task is made more difficult today - in philosophy, not in classical philology - by the influence of Heidegger and his school. Although he recognized very clearly the rationalist, Enlightenment
? ? , t. "
? ? LECTURE FOUR 21
? ? moment in Aristotle, Heidegger attempted to rediscover a much more 'pristine' Aristotle, to an extent which is hard to conceive. And be- fore going on to Aristotle I think I need to offer a brief critique of this approach. I'd like to do this by examining closely a very specific piece of interpretation, since I believe that such things are more clearly revealed by concrete details, rather than by remaining on the level of general assertion. I am concerned here with the first sentence of Aristotle's Metaphysics, and I shall consider only this one sentence. I shall write this sentence in Greek on the blackboard; I am aware that many of you do not know Greek, but there is no other way to proceed; and I shall explain everything you need to know in order to understand it. The sentence is as follows: lluv'TE'; av&pw7TOt 'TOU do/vat 0p/yov'Tat cpVUEt. I2 According to the generally accepted trans- lations, this means: people by nature strive after knowledge. A well- known translation renders it as: 'All men by their very nature feel the urge to know. '13 This sentence is reproduced in Heidegger's Being and Time (please keep in mind the usual translation: all people by nature strive zealously after knowledge). Heidegger's version - which, incidentally, is presented cautiously, not as a direct translation - is as follows: 'The treatise which stands first in the collection of Aristotle's treatises on ontology begins with the sentence: lluv'TE'; av&pw7TOt 'TOU
dOEvat 0p/yov'Tat cpVUEt. The care for seeing is essential to man's Being. ' It is not my purpose here to poke fun at the stiltedness of this passage, for a mannered, estranging approach to a strange text can have a very salutary function. And I'd like to say at once that Heidegger offers resistance to the flattening out of Greek texts when rendered into our language, as has traditionally been done. How- ever, his interpretation here does not produce simply the salutary alienation effect I referred to, but violates the meaning on the most literal level. When he says, for example: 'man's Being rim Sein des Menschen]',t4 the human being is already put in the singular, pre- supposing a priority of the essence of the human being, and thus a kind of anthropological ontology, which in Aristotle is still to be established. I5 Aristotle does not say 'the human being', or 'existence as such', but simply and plainly 'all people', 'the people', and not 'individual people'. For dO/vat means quite simply to know, and av&pw1TOt 'TOU dOEVat OpEyoV'Tat means: people earnestly seek or strive after knowledge. Now it is undoubtedly correct, as I had occasion to indicate to you earlier,16 that this dO/VaL contains the stem [f]to, which is also in lOEa and which characterizes the sensory relationship of seeing. But in his interpretation Heidegger simply suppresses the whole history of language which, starting from the rich, sensible
? conceptions originally associated with words, progressively sublimated
?
?
22
LECTURE FOUR
? ? the words into concepts. This happened in Greek just as it has happened in our language. There can be no doubt that at the stage when Aristotle wrote, EtOEVat already meant to know in the sense of a consciousness emancipated from the sensible present. But because ontology, which in Aristotle is only a theme for discussion, is, as I have said, presupposed by Heidegger in an act of 're-pristination', consciousness is supposed to have a direct sensible perception of
essence, or being, or whatever it may be, as if it were something existing in itself. And so Heidegger translates this EtOEVat back to its much earlier lineage as sensible presence, although by this stage it had entirely lost that quality.
He then says that 'the care of seeing is essential to man's Being' [Im Sein des Menschen liegt wesenhaft die Sorge des Sehens]. Here it becomes blatantly clear what Heidegger is up to. Anyone even slightly acquainted with the history of ancient philosophy and having the
rudiments of Greek will know that the word CPVUEt is a philosophical term which - about a hundred years before Aristotle; I cannot give you the exact date - played a part in Socraticism and Sophism, in opposition to {fEUEt, as that which is so 'by nature', as against what is merely posited, what is {fEUEt. The term for 'essential' would be quite different, perhaps QV'TWS- or QV'TWS- QV, as it appears in Plato; but quite certainly not CPVUEt, since there is in CPVUEt an echo of cpvms- and thus a memory of physical nature from the old hylozoistic period. So the sentence means quite simply - very much in keeping with the men- tality of Aristotle, who was a peculiar mixture of an ontologist and a professor of physics - that human beings, as they are, strive by nature for knowledge. But as for the idea that this was meant in the sense17 of some definite ontological pre-structuring of existence in which being was to be revealed - no shadow of that is to be found in Aristotle. Finally, the word 0pEyw{fat means no more than to exert
? oneself, to long for, to strive after something - and has not the slight- est connection with care [Sorge], which, as we know, is one of the core categories in Heidegger. On the contrary, the straightforward
'love of wisdom,18 has had foisted on it an existential interpretation - that it harbours the care of Dasein for its being - although, as you will see in any dictionary, no philology or linguistic knowledge can produce a link between this 0pEyw{fat and the concept of care.
In examining this sentence in some depth I believe I have shown you what I wanted to develop as the main idea of this lecture: that
Aristotle starts out from an everyday, rational, sensible conscious- ness and attempts, by reflecting on what is given directly by the
senses, to attain insight into true being - instead of presupposing this essential realm, as was the case in archaic thought. If that were not
LECTURE FOUR 23
? ? the case - if this sentence were as Heidegger interprets it - then Aris- totle would not really be a metaphysician, but precisely the onto- logist which, in a different place, Heidegger says he is not. 19 But the moment of tension in metaphysics is located exactly in this seemingly straightforward, empirical sentence, in which, however, the striving for knowledge and thus, objectively, for absolute truth, is posited as
need - so that here, too, everything is finally constituted from the point of view of truth. And this really defines quite clearly the intel- lectual climate within which Aristotle's Metaphysics has its place. In the next lecture it will be time to tell you something about the con- tent of the Metaphysics.

? ? ? I shall start today by presenting to you, as best I can, some of the main ideas in Aristotle's Metaphysics; this will lead on to some reflections on the problem of metaphysics in general. I shall base my exposition mainly on the account given by Eduard Zeller,1 although I am well aware that, with regard to philological details, scholarship on Aris- totle has made extraordinary progress since the time of Zeller's work. I should like to take this opportunity to say, however, that much of this detailed progress seems to me to have been at the expense of philosophical vision, which was available to Zeller as a member of the Hegelian school to a degree which has subsequently been entirely lost. I therefore prefer the overview and insight he gives us in his
book to a possibly greater accuracy of detail, as I am more concerned to throw light on the problems and history of metaphysics through Aristotle than to give you an irreproachably punctilious account of that philosopher's work.
The definition of metaphysics is to be found in the first book, Book A. It agrees with what I have already told you about the themes of metaphysics/ even though its subject matter is somewhat narrower than the diversity of themes we are accustomed to associate with that term. The book states that metaphysics is the 'science of first prin- ciples and causes';3 one is struck first, of course, by the link with the Platonic doctrine of Ideas, which likewise promises to deal with the first principles, the highest concepts, the causes of phenomena. The first complex which can be extracted from Aristotle's work Meta- physics4 and which is fundamental to all the rest - I'm expressly
? ? LECTURE FIVE
25
? following Zeller in this - is the complex of the particular and the universal, which can be said to be really the basic theme of Aris- totelian Metaphysics. And I should point out to you straight away that in the case of Aristotle - unlike that of Plato - one can talk of a system, to the extent that the methodological and, above all, the epistemological considerations we are accustomed to summarize under the title of the Organon are so closely bound up with the argumentation of the Metaphysics that some of the main arguments of the latter work go back to these methodological writings, the
Organon. In particular, they go back within this methodological cor- pus to the work on the Categories (KaTYJyop{at). I shall only touch on the fact that 'categories' in Aristotle means something quite differ- ent than it does in Kant, namely the basic forms which are brought to light by an analysis of the procedures of speech, and not the basic subjective forms of thought; I assume that most of you are aware of this. s In starting from the problem of the particular and the universal in Aristotle, I am following up something I set out in the last lecture, the idea that metaphysics in general has the dual character of the crit- ical or, as is often said, the destructive, and of the apologetic and rescuing; and you will see that this characterization applies in an exceptional degree to Aristotle.
It can be said that his treatise - I mean his deliberations, since they were not contained in a separate treatise - his deliberations on the problem of the particular and the universal, fall initially within the
sphere of his critical work. However, the accent here is on 'initially', and this gives rise to a problem with which the whole of Aristotle's Metaphysics confronts us. The first thesis, it might be said, is that the universal is not substantial; that it is not, like the Platonic Ideas, which are universal concepts, something existing in and for itself, independently of its realization. Rather, one can only speak of a universal to the extent that it manifests itself in a particular. In other words, reflection on the process of abstraction has much more force in Aristotle's deliberations on the universal than it had in Plato, but
does not go so far as to conceive universal concepts as pure abstrac- tions. Rather, the difficulty and, if I might put it thus, the point of Aristotle's Metaphysics is that while, on the one hand, one cannot think of the universal independently of that in which it is concret- ized, on the other hand, it is not a mere abstraction in relation to the particulars subsumed under it. If you can picture the problem in this accentuated form, I believe you will be able to cope with the difficulties of this theory straight away. In general, one can only deal with difficulties by looking them in the eye. And Aristotle does make things rather difficult for us by presenting himself as a

'commonsensical' type of thinker in whose work, as in that of a number of British thinkers later, the most unfathomable problems appear initially as if they could yield self-evident answers to simple human understanding, whereas in reality they conceal abysses. I touch here on the specific difficulty presented by an interpretation of Aris- totle as a whole. Let me return now to what I indicated at the outset, that I should like to relate my exposition of Aristotle to the history and overall themes of western metaphysics. It can be said that his doctrine that the universal is not a substantial moment contains the
seeds of what is called nominalism, which holds that universal con- cepts exist post rem and not ante rem. But - and I say this to exclude all misunderstandings from the outset - it would be a grave mis- understanding to describe Aristotle himself as a nominalist. I could say that his Metaphysics circles around this theme; that its problem lies precisely in the contradictory situation whereby on one hand the
universal is denied substantiality while, on the other, universal con- cepts are not mere abbreviations of the particulars subsumed under them - rather, they have an attribute which raises them above flatus vocis, above the mere breath of the voice. And if you want to under- stand the concept of metaphysics, you must pay attention from the first to this constellation of moments in Aristotle's Metaphysics. He says that, in contrast to the universal, only the particular is substan- tial; that only the single, apparent, concrete phenomenon is real. This concept of reality or, better, this concept of the substantial in his work, is denoted by the noun ovuta, from which the Latin term for substance is derived/ and which itself is derived from Elvat, to be.
This ovuta, or 1TPWT17 ovu{a, 'primary being', constitutes, from this perspective, the quintessential theme of Aristotle's work. Only the particular shall, to begin with, be such an ovu{a; only it shall be real.
This takes us to the second basic thesis of Aristotle's Metaphysics concerning the relationship of universal to particular: the thesis that essence or, as Plato would say, the Idea, does not lie outside the things whose essence it is, but is only in so far as it is in things themselves. In other words, Plato's basic doctrine, concerning the xwpw/-to,; of the Ideas as against the existent, the 'abyss of meaning,7
which separates the Ideas or the universal concepts from the concrete individual things subsumed by them, is challenged by Aristotle. And his approach has what looks like a thoroughly progressive and mod- ern moment in stating that, if I separate the Ideas completely from everything existent and make them absolutely autonomous, I turn them into an existent of a second power, of a second, higher order. In modern terms we would say that I objectify or reify the Ideas. And from this he derived the entirely plausible objection that the whole
? ? LECTURE FIVE 27
? ? world would then be duplicated; on one hand there would be a world which is mere appearance and on the other a world which is being- in-itself, but which borrows all its qualities from the empirical world,
so that it reappears in the latter - from which issue all kinds of logical conundrums. I shall point out in passing (to show you how contemporary all these Aristotelian questions are) that exactly the same problem makes itself felt in modern epistemology and meta- physics, as when Husserl posits a region of pure essences - of, shall
we say, immanent consciousness - and a region comprising the high- est unity of psychological determination; this would give rise to a double world: on one side a highly formalized psychology and on the other a doctrine of pure essences, of the forms of consciousness.
Finally, if the Ideas are presented as absolutely xwp{,;, absolutely separate, as was the case in Plato, this gives rise to a second inconsist- ency of which Aristotle accuses Plato, and which forms the pivot of his own Metaphysics. It then becomes inconceivable how - as Plato taught and as Aristotle himself teaches with even greater emphasis - the universal, the Ideas, could have any motive force, or how far they could be the causes of their own appearances; for they are said to be absolutely separate from precisely the phenomenal world they are supposed to move. And when we are faced by such a division, by the positing of two absolutely different spheres, one of which, for the sake of brevity, we shall call the ontological and the other the ontic, the sphere of existing things, it is simply impossible to conceive how
one might interact with the other, as Plato - and Aristotle again demonstrates this with great critical acuity - steadfastly teaches. This problem, too - how it is possible for a pure idea to be an efficient force acting on phenomena - has cropped up throughout the entire history of philosophy. I should like to illustrate it (again with regard to the persistent influence of this idea on the history of metaphysics in particular) by the example of Kant's Critique of Practical Reason. The problem with which this work of moral philosophy grapples
above all (although he never states squarely that this is its real con- cern) is how the moral law, which is something purely spiritual, arising from the intelligible world and independent of any empirical determination, manages to act upon the empirical world - as a com- pulsion or duty to act in accordance with the ideas. s If you look at
the Critique ofPractical Reason from this point of view, you will see that Kant took enormous pains in trying to resolve this question; and that he was only finally able to do so by the complete intellectualiza- tion of the will, so that even those acts which affect the empirical world through the pure ideas are conceived as purely intellectual acts. Kant fails here to realize that if these acts are purely intellectual one

,
cannot really understand how th(! y could become objective, how they could objectify themselves at all in the world of phenomena. This problem, therefore, which can b(! levelled as criticism against Kant's Metaphysics of Morals, is already fully contained in Aristotle's Metaphysics, in the form of his r(! alization that if the Ideas or univer-
sal concepts are absolutely xwp{,;, that is, a realm of autonomous essence, it is impossible to conceive how and how far they can be causes of phenomena.
Now, the argument for the thesis of the substantiality of the par- ticular, which I mentioned to you, is that nothing which is predicated on some other, underlying thing can be substantial. That is, only that is substantial which does not need something else in order to exist. And with regard to the ovu{a, in the sense of particular things, he now argues, somewhat curiously, that this characteristic - that we do not need anything else in order to recognize it - is possessed only by particular things. This version of the concept of substance is a fun- damental thesis of western metaphysics. It holds that the substantial is that which needs nothing else in order to exist; this tenet has
been handed down by scholasticism and, remarkably, reappears in the philosophy of Descartes. As Koyre has shown/ Descartes's philo- sophy is linked to scholasticism to an extraordinary degree, far more extensively than one would expect, given Descartes's polemical atti- tude towards his educators. Yet this concept of substance recurs in the Principia, in the famous formulation that substance is that 'quod nulla re indiget ad existendum';l0 that is, which needs no other thing in order to exist. And if you will permit me a brief historical aside, this interpretation of substance, as that which needs nothing else in order to exist, has survived throughout the entire history of philosophy. Not only is this definition of the concept of substance to be found among Spinoza's famous definitions in the Ethics,! 1 for example, but it even re-emerges in modern philosophy, in Husserl's
Ideas: General Introduction to Pure Phenomenology. 12 Precisely this theorem of Descartes, incidentally, has its origin in the 'doctrine of categories' in the Organon. 13 In Aristotle, therefore, metaphysics is as tightly bound up with logic and epistemology as it was to be again at the height of western philosophy, in Kant and Hegel.
I should like to point out that this thesis includes something which is not said in as many words but which has its origin here and forms part of the bedrock, if you will, of the whole of western thought. We are all brought up so much within it that (until philosophical reflec-
tion liberates us) we take it for granted; it is truly like second nature to the mind. According to this doctrine, that thing is substantial - in the sense that it needs nothing else - which requires no means by
? ? 28
? ? ? LECTURE FIVE 29
? which we can perceive it; it is, in other words, the immediate. Thus, at the beginning of western metaphysics, stands the statement that that on which everything is supported, on which everything depends and by which knowledge should be orientated, is the immediate -
the form of the particular which Aristotle first equates with that which really and truly exists. However, at this point you must also be aware of a difference. For with a thinker as deeply connected to
western philosophy as Aristotle it is especially important to differen- tiate historically, to avoid producing a general philosophical mush in which everything communicates with everything else. The immediacy implied in the basic doctrines of Aristotle that I have set out for you is not conceived by him - at least, not primarily - as the immediacy of sensory experience. It is not, therefore, an immediacy in relation to our capacity for knowledge. And it can be assumed that Aristotle, as a pupil of Plato, was acquainted with the critique of the immediacy of subjective sensory certainty in the Theaetetus,14 and that he had assimilated it into his thought. His immediacy, therefore, is not an immediacy of consciousness, it is not 'les donnees immediates de la conscience',15 but, if one can put it so paradoxically, it is the immedi- ate in itself. Here, of course, critical reflection is at once confronted with the question of how one can speak of 'immediacy in itself' at all,
since any such immediacy, about which something is predicated, can only be immediacy for a consciousness which predicates it.
But, apart from that, I'd like to make another criticism here - not just for the sake of criticizing a historical thinker, since such an attempt would display a naivety which, I assume, you would not expect from me any more than from yourselves. I make it in order
to show you that a theory like the one I am expounding leads to extraordinary difficulties within itself. For to introduce you to Aris- totle's Metaphysics cannot be simply to set out his main theses; it must give you an awareness of the problems of his metaphysics. And to do that is necessarily to point to the difficulties which are con- cealed beneath the plausibility of the argumentation. Now, Hegel taught that there is no immediacy which is not at the same time mediated. 16 If you accept that Hegel successfully proves this point -
and I would think that there are few moments in Hegel's Logic which are as obviously convincing as this proof17 - it is no longer clear what the traditional metaphysical notion of substance, as that which absolutely requires no mediation, is supposed to mean. And it seems to me to be one of those curious anachronisms, not to say archaisms,
which the history of philosophy, and especially of metaphysics, drags along with it, that while it engaged in the critical reflections on the concept of immediacy that I have just described, it did not perceive
in
? ?
30 LECTURE FIVE
? that the doctrine of substance, that is, the conception of substance as that which exists primarily and immediately in itself, was necessarily and profoundly affected by those reflections. If I were to say to you that philosophy has taken too little notice of this throughout its history, that would be unjust and incorrect. It has, of course, taken notice, in the form of radical nominalism, but it has not taken notice in its rationalist-speculative-idealist mainstream, if I may put it like that. It is certainly the case that Hume, who, if you like, represents
the furthest logical conclusion to be drawn from Aristotle's doctrine of the reality of the particular, disintegrated the notion of substance for this very reason. That is to say that the concept of substance, at first inseparably bound up with the concept of the particular thing, gives way in his thought to a critique which states that the thing itself does not really exist, but only the habitual associations of subjective modes of appearance, which we then conventionally regard as things. In accordance with this, Kant turned the concept of substance into a subjective function, an activity - something which the mind produces within objects, and no longer the thing existing in itself which Aristotle terms substance qua thing. On the other hand, however, in his doctrine of ideas and, in general, in his conception of the mundus intelligibilis, the intelligible world, the notion of substance in the old Aristotelian sense still prevails in Kant's thought. 18 You can see at this point how the logical conclusion later drawn from the doctrine which begins with Aristotle - that full reality can only be attributed to particular things - resulted from an attitude which, as I said earlier, was foreign to Aristotle and to antiquity (with the exception of Sophism): the orientation towards the subject. Only when the doctrine of the reality and immediacy of the particular is combined with the conception that this immediacy is only an immediacy for the subject, is a thoroughgoing nominalism, of the kind I have just briefly illustrated by the example of Hume, possible. And, to put the matter negatively, that is also the reason why one cannot speak of nominal-
ism in Aristotle, despite the incipient tendency towards it that I have indicated. How the matter might be stated positively - you will see in a moment. To put it quite simply, there is something naively realistic in the notion of substance as used by Aristotle, and you will only be able correctly to understand his Metaphysics as a whole - something which is not easy for us today - if you do not see it in terms of our ubiquitous subjective reflection, but, to use an expression from
of of
scholasticism, in intentione recta. That means, to see it in terms the immediate objectivity of the external world, and not in terms mediation through the perceiving consciousness.

? This curious intersection between the doctrine of the reality of the particular and, at the same time, a naively outward-turned realism, is another necessary feature of the structures of Aristotle's thought. Now, the truly Aristotelian element, which constitutes the entire difficulty I have been speaking about, is the fact that, despite this fundamental postulate of the reality of the particular, and the assertion that only that is substantial which does not need anything else but exists im- mediately, he was very emphatically a philosopher of mediation. To understand how this idea or (one might almost say) this cult of the immediate, of the existent in itself, is entwined in Aristotle's thought with the idea of universal mediation, is the fundamental problem in understanding the Metaphysics; and I would ask you to concentrate on this problem. You will then see - to jump ahead - that the con- cept of mediation found in Aristotle is extraordinarily different from that which those with a Hegelian training - and there will be more than a few of them among you - understand by mediation. Here, too, I would repeat like a scholastic: distinguo, I distinguish. You can only grasp the specific nature of Aristotle's approach if you dist- inguish very strictly what is meant by mediation, by middle (Mitte),
and by the intermediate (das Mittlere) in Aristotle from what they mean in the dialectic. For, to state this in advance, Aristotle was anything but a dialectical thinker, although he was at the same time a thinker of immediacy and a thinker of mediation. One might say, if I might give this a Hegelian twist, that the thesis of immediacy and the thesis of mediateness were themselves not mediated in his work - if you will allow me to make a dialectical point at this juncture. Of course, this was not such a crucial issue for Aristotle, since the dialectic did not exist at that time, so that he could not distance or differentiate his method from it in the way I have just done. Rather,
it is in keeping with the whole temper of Aristotle's philosophy, which is one of limitation, of respect, of moderation, of /1-W6TYJ<;, that he softens and limits the doctrine of substantiality as immediacy by introducing the idea of improper or secondary substances, which he calls 8EVTEpat ova{at, 'second substances'. One might also refer to them, perhaps, as second essences;19 although the word 'second' clearly indicates that they are not pure immediacies but products of abstrac- tion. They are 'second' because they only come into being on the basis of what is given primarily, particular things. These 8EVTEpat ovatat, these secondary or improper substances, cannot be hypostatized, as one would say in modern philosophical terminology, but are con- tained in particular things; they are thus immanent and not tran-
scendent. And this thesis - that although on the one hand substantial
?
? 32
LECTURE FIVE
concepts exist, they are not xwp{? , they do not have their being beyond individual existing things, but are only embodied in them and are immanent to them - is really the basic thesis of the whole of Aristotle's Metaphysics. It is the source of the fundamental difference between this philosophy and Plato's - its dynamic character. For if these 8ELITEpat ova{at are immanent in particular things, instead of standing opposed to them as something external and alien, it is no longer absurd or inconceivable, Aristotle argues, that these essences
should have an effect on particular things, or that a mediation should be established between the Idea and scattered existence. I should like to close with that remark, and will continue from this point in the
next lecture.
