No More Learning

This argument
would be a valid one if all men of all races had the same inward
conviction of the existence of one God; but we know that this
is very far from being the case. Therefore I cannot see that
such inward convictions and feelings are of any weight as evi-
dence of what really exists. The state of mind which grand
scenes formerly excited in me, and which was intimately con-
nected with a belief in God, did not essentially differ from that
which is often called the sense of sublimity; and however diffi-
cult it may be to explain the genesis of this sense, it can hardly
be advanced as an argument for the existence of God, any more
than the powerful though vague and similar feelings excited by
music.
With respect to immortality, nothing shows me [so clearly]
how strong and almost instinctive a belief it is, as the consid-
eration of the view now held by most physicists, namely, that
the sun with all the planets will in time grow too cold for life,
unless indeed some great body dashes into the sun, and thus
gives it fresh life. Believing as I do that man in the distant
future will be a far more perfect creature than he now is, it is
an intolerable thought that he and all other sentient beings
are doomed to complete annihilation after such long-continued
slow progress.

the human soul, the destruction of our world will not appear so
dreadful.
Another source of conviction in the existence of God, con-
nected with the reason, and not with the feelings, impresses me
as having much more weight. This follows from the extreme
difficulty or rather impossibility of conceiving this immense and
wonderful universe, including man, with his capacity of looking
far backward and far into futurity, as the result of blind chance
or necessity. When thus reflecting I feel compelled to look to a
First Cause, having an intelligent mind in some degree anal-
ogous to that of man; and I deserve to be called a Theist.
This conclusion was strong in my mind about the time, as far
as I can remember, when I wrote the 'Origin of Species'; and
it is since that time that it has very gradually, with many
fluctuations, become weaker. But then arises the doubt: Can the
mind of man, which has, as I fully believe, been developed
from a mind as low as that possessed by the lowest animals, be
trusted when it draws such grand conclusions ?
I cannot pretend to throw the least light on such abstruse
problems. The mystery of the beginning of all things is insoluble
by us; and I for one must be content to remain an Agnostic.

SOME
COME one has sent us 'Macmillan,' and I must tell you how
much I admire your article; though at the same time I
must confess that I could not clearly follow you in some
parts, which probably is in main part due to my not being at all
accustomed to metaphysical trains of thought. I think that you
understand my book perfectly, and that I find a very rare event
with my critics. The ideas in the last page have several times
vaguely crossed my mind. Owing to several correspondents I
have been led lately to think, or rather to try to think, over
some of the chief points discussed by you. But the result has
been with me a maze-something like thinking on the origin of
evil, to which you allude. The mind refuses to look at this
universe, being what it is, without having been designed; yet

where one would most expect design,- viz. , in the structure of
a sentient being,- the more I think on the subject, the less I
can see proof of design. Asa Gray and some others look at each
variation, or at least at each beneficial variation (which A. Gray
would compare with the rain-drops which do not fall on the sea,
but on to the land to fertilize it), as having been providentially
designed. Yet when I asked him whether he looks at each
variation in the rock-pigeon, by which man has made by accumu-
lation a pouter or fantail pigeon, as providentially designed for
man's amusement, he does not know what to answer; and if he
or any one admits [that] these variations are accidental, as far
as purpose is concerned (of course not accidental as to their
cause or origin), then I can see no reason why he should rank
the accumulated variations by which the beautifully adapted
woodpecker has been formed, as providentially designed. For it
would be easy to imagine the enlarged crop of the pouter, or
tail of the fantail, as of some use to birds in a state of nature,
having peculiar habits of life. These are the considerations
which perplex me about design; but whether you will care
hear them, I know not.
[On the subject of design, he wrote (July 1860) to Dr.
Gray: -]
One word more on "designed laws" and "undesigned results. "
I see a bird which I want for food, take my gun and kill it; I
do this designedly. An innocent and good man stands under a
tree and is killed by a flash of lightning. Do you believe (and
I really should like to hear) that God designedly killed this man?
Many or most persons do believe this; I can't and don't.
If you
believe so, do you believe that when a swallow snaps up a gnat,
that God designed that that particular swallow should snap up
that particular gnat at that particular instant? I believe that
the man and the gnat are in the same predicament. If the
death of neither man nor gnat is designed, I see no good
reason to believe that their first birth or production should be
necessarily designed.

CORRESPONDENCE
From The Life and Letters'
.
C. DARWIN TO J. D. HOOKER
My Dear Hooker:
I
AM astonished at your note. I have not seen the Athenæum,
but I have sent for it, and may get it to-morrow; and will
then say what I think.
Down, February 24th [1863].
I have read Lyell's book [The Antiquity of Man']. The
whole certainly struck me as a compilation, but of the highest
class; for when possible the facts have been verified on the spot,
making it almost an original work. The Glacial chapters seem
to me best, and in parts magnificent. I could hardly judge about
Man, as all the gloss of novelty was completely worn off. But
certainly the aggregation of the evidence produced a very strik-
ing effect on my mind. The chapter comparing language and
changes of species seems most ingenious and interesting. He has
shown great skill in picking out salient points in the argument
for change of species; but I am deeply disappointed (I do not
mean personally) to find that his timidity prevents him giving
any judgment.
From all my communications with him,
I must ever think that he has really entirely lost faith in the
immutability of species; and yet one of his strongest sentences is
nearly as follows: "If it should ever be rendered highly probable
that species change by variation and natural selection," etc. , etc.
I had hoped he would have guided the public as far as his own
belief went.
One thing does please me on this subject,
that he seems to appreciate your work. No doubt the public or
a part may be induced to think that as he gives to us a larger
space than to Lamarck, he must think there is something in our
views. When reading the brain chapter, it struck me forcibly
that if he had said openly that he believed in change of species,
and as a consequence that man was derived from some quadru-
manous animal, it would have been very proper to have discussed
by compilation the differences in the most important organ, viz. ,
the brain. As it is, the chapter seems to me to come in rather
by the head and shoulders. I do not think (but then I am as
prejudiced as Falconer and Huxley, or more so) that it is too

It might per-
severe. It struck me as given with judicial force.
haps be said with truth that he had no business to judge on a
subject on which he knows nothing; but compilers must do this
to a certain extent. (You know I value and rank high com-
pilers, being one myself. ) I have taken you at your word, and
scribbled at great length. If I get the Athenæum to-morrow, I
will add my impression of Owen's letter.
The Lyells are coming here on Sunday evening to stay till
Wednesday. I dread it, but I must say how much disappointed
I am that he has not spoken out on species, still less on man.
And the best of the joke is that he thinks he has acted with the
courage of a martyr of old. I hope I may have taken an exag-
gerated view of his timidity, and shall particularly be glad of
your opinion on this head. When I got his book I turned over
the pages, and saw he had discussed the subject of species, and
said that I thought he would do more to convert the public than
all of us; and now (which makes the case worse for me) I must,
in common honesty, retract. wish to Heaven he had said not
a word on the subject.
WEDNESDAY MORNING. I have read the Athenæum. I do
not think Lyell will be nearly so much annoyed as you expect.
The concluding sentence is no doubt very stinging.
No one
but a good anatomist could unravel Owen's letter; at least it is
quite beyond me.
Lyell's memory plays him false when he says all anatomists
were astonished at Owen's paper: it was often quoted with
approbation. I well remember Lyell's admiration at this new
classification! (Do not repeat this. ) I remember it because,
though I knew nothing whatever about the brain, I felt a con-
viction that a classification thus founded on a single character
would break down, and it seemed to me a great error not to
separate more completely the Marsupialia.
What an accursed evil it is that there should be all this quar-
reling, within what ought to be the peaceful realms of science.
I will go to my own present subject of inheritance and forget
it all for a time. Farewell, my dear old friend.

My Dear Sir:
I Do not know whether you will consider me a very trouble-

praise. I have been all the more interested, as I am now
writing on closely allied though not quite identical points. I
was pleased to see you refer to my much despised child,
'Pangenesis,' who I think will some day, under some better
nurse, turn out a fine stripling. It has also pleased me to
see how thoroughly you appreciate (and I do not think that
this is general with the men of science) H. Spencer; I sus-
pect that hereafter he will be looked at as by far the greatest
living philosopher in England; perhaps equal to any that have

FROM A LETTER TO J. D. HOOKER
CLIFF COTTAGE, BOURNEMOUTH, September 26th, 1862.
My Dear Hooker:
Do NOT read this till you have leisure. If that blessed
moment ever comes, I should be very glad to have your
opinion on the subject of this letter. I am led to the opin--
ion that Drosera must have diffused matter in organic con-
nection, closely analogous to the nervous matter of animals.
When the glans of one of the papillæ or tentacles in its natural
position is supplied with nitrogenized fluid and certain other
stimulants, or when loaded with an extremely slight weight, or
when struck several times with a needle, the pedicel bends near
its base in under one minute. These varied stimulants are con-
veyed down the pedicel by some means; it cannot be vibration,
for drops of fluid put on quite quietly cause the movement; it
cannot be absorption of the fluid from cell to cell, for I can see
the rate of absorption, which, though quick, is far slower, and in
Dionæa the transmission is instantaneous; analogy from animals
would point to transmission through nervous matter. Reflecting
on the rapid power of absorption in the glans, the extreme
sensibility of the whole organ, and the conspicuous movement
caused by varied stimulants, I have tried a number of substances
which are not caustic or corrosive,
but most of which
are known to have a remarkable action on the nervous matter
of animals. You will see the results in the inclosed paper. As
the nervous matter of different animals is differently acted on
by the same poisons, one would not expect the same action on
plants and animals; only, if plants have diffused nervous matter,
some degree of analogous action. And this is partially the case.
Considering these experiments, together with the previously
made remarks on the functions of the parts, I cannot avoid the
conclusion that Drosera possesses matter at least in some degree
analogous in constitution and function to nervous matter. Now
do tell me what you think, as far as you can judge from my
abstract. Of course many more experiments would have to be

tried; but in former years I tried on the whole leaf, instead of
on separate glands, a number of innocuous substances, such as
sugar, gum, starch, etc. , and they produced no effect. Your
opinion will aid me in deciding some future year in going on
with this subject. I should not have thought it worth attempt-
ing, but I had nothing on earth to do.

THE STRUGGLE FOR EXISTENCE
From the Origin of Species >
BE
EFORE entering on the subject of this chapter, I must make a
few preliminary remarks, to show how the struggle for
existence bears on Natural Selection. It has been seen in
the last chapter that amongst organic beings in a state of nature
there is some individual variability; indeed, I am not aware that
this has ever been disputed. It is immaterial for us whether
a multitude of doubtful forms be called species, or sub-species,
or varieties; what rank, for instance, the two or three hundred
doubtful forms of British plants are entitled to hold, if the exist-
ence of any well-marked varieties be admitted. But the mere
existence of individual variability and of some few well-marked
varieties, though necessary as the foundation for the work, helps
us but little in understanding how species arise in nature. How
have all those exquisite adaptations of one part of the organiza-
tion to another part, and to the conditions of life, and of one
organic being to another being, been perfected? We see these
beautiful co-adaptations most plainly in the woodpecker and the
mistletoe; and only a little less plainly in the humblest parasite
which clings to the hairs of a quadruped or feathers of a bird;
in the structure of the beetle which dives through the water; in
the plumed seed which is wafted by the gentlest breeze: in
short, we see beautiful adaptations everywhere and in every part
of the organic world.
Again, it may be asked, how is it that varieties, which I have
called incipient species, become ultimately converted into good
and distinct species, which in most cases obviously differ from
each other far more than do the varieties of the same species?


## p. 4415 (#185) ###########################################

CHARLES ROBERT DARWIN
4415
How do those groups of species, which constitute what are
called distinct genera, and which differ from each other more
than do the species of the same genus, arise? All these results,
as we shall more fully see in the next chapter, follow from the
struggle for life. Owing to this struggle, variations, however
slight and from whatever cause proceeding, if they be in any
degree profitable to the individuals of a species, in their infi-
nitely complex relations to other organic beings and to their
physical conditions of life, will tend to the preservation of such
individuals, and will generally be inherited by the offspring.
The offspring also will thus have a better chance of surviving;
for of the many individuals of any species which are periodically
born, but a small number can survive. I have called this prin-
ciple, by which each slight variation, if useful, is preserved, by
the term Natural Selection, in order to mark its relation to
man's power of selection. But the expression often used by Mr.
Herbert Spencer, of the Survival of the Fittest, is more accurate
and is sometimes equally convenient. We have seen that man
by selection can certainly produce great results, and can adapt
organic beings to his own uses, through the accumulation of
slight but useful variations given to him by the hand of Nature.
But Natural Selection, as we shall hereafter see, is a power
incessantly ready for action, and is as immeasurably superior
to man's feeble efforts as the works of Nature are to those
of Art.
We will now discuss in a little more detail the struggle for
existence. In my future work this subject will be treated, as it
well deserves, at greater length. The elder De Candolle and
Lyell have largely and philosophically shown that all organic
beings are exposed to severe competition. In regard to plants,
no one has treated this subject with more spirit and ability than
W. Herbert, Dean of Manchester, evidently the result of his
great horticultural knowledge. Nothing is easier than to admit
in words the truth of the universal struggle for life, or more
difficult at least I have found it so-than constantly to bear
this conclusion in mind. Yet unless it be thoroughly ingrained
in the mind, the whole economy of nature, with every fact on
distribution, rarity, abundance, extinction, and variation, will be
dimly seen or quite misunderstood. We behold the face of
nature bright with gladness, we often see superabundance of
food; we do not see, or we forget, that the birds which are idly

4416
CHARLES ROBERT DARWIN
singing round us mostly live on insects or seeds, and are thus
constantly destroying life; or we forget how largely these song-
sters, or their eggs, or their nestlings, are destroyed by birds
and beasts of prey; we do not always bear in mind that though
food may be now superabundant, it is not so at all seasons of
each recurring year.
I should premise that I use this term in a large and meta-
phorical sense, including dependence of one being on another,
and including (which is more important) not only the life of the
individual, but success in leaving progeny. Two canine ani-
mals, in a time of dearth, may be truly said to struggle with
each other which shall get food and live. But a plant on the
edge of a desert is said to struggle for life against the drought,
though more properly it should be said to be dependent on the
moisture. A plant which annually produces a thousand seeds, of
which only one on an average comes to maturity, may be more
truly said to struggle with the plants of the same and other
kinds which already clothe the ground. The mistletoe is depend-
ent on the apple and a few other trees, but can only in a far-
fetched sense be said to struggle with these trees, for if too
many of these parasites grow on the same tree, it languishes
and dies. But several seedling mistletoes, growing close to-
gether on the same branch, may more truly be said to struggle
with each other. As the mistletoe is disseminated by birds, its
existence depends on them; and it may metaphorically be said
to struggle with other fruit-bearing plants, in tempting the
birds to devour and thus disseminate its seeds. In these several
senses, which pass into each other, I use for convenience's sake
the general term of Struggle for Existence.
THE GEOMETRICAL RATIO OF INCREASE
From Origin of Species>
A
STRUGGLE for existence inevitably follows from the high rate
at which all organic beings tend to increase. Every being
which during its natural lifetime produces several eggs or
seeds must suffer destruction during some period of its life, and
during some season or occasional year; otherwise, on the princi-
ple of geometrical increase, its numbers would quickly become

CHARLES ROBERT DARWIN
4417
so inordinately great that no country could support the product.
Hence, as more individuals are produced than can possibly sur-
vive, there must in every case be a struggle for existence, either
one individual with another of the same species, or with the
individuals of distinct species, or with the physical conditions of
life. It is the doctrine of Malthus applied with manifold force
to the whole animal and vegetable kingdoms; for in this case
there can be no artificial increase of food, and no prudential
restraint from marriage. Although some species may be now
increasing, more or less rapidly, in numbers, all cannot do so,
for the world would not hold them.
There is no exception to the rule that every organic being
naturally increases at so high a rate that if not destroyed, the
earth would soon be covered by the progeny of a single pair.
Even slow-breeding man has doubled in twenty-five years; and
at this rate, in less than a thousand years there would literally
not be standing-room for his progeny. Linnæus has calculated
that if an annual plant produced only two seeds-and there is
no plant so unproductive as this-and their seedlings next year
produced two, and so on, then in twenty years there would be a
million plants. The elephant is reckoned the slowest breeder of
all known animals, and I have taken some pains to estimate its
probable minimum rate of natural increase; it will be safest to
assume that it begins breeding when thirty years old: and goes
on breeding till ninety years old, bringing forth six young in
the interval, and surviving till one hundred years old: if this be
so, after a period of from 740 to 750 years there would be
nearly nineteen million elephants alive, descended from the first
pair.
But we have better evidence on this subject than mere theo-
retical calculations, namely, the numerous recorded cases of the
astonishingly rapid increase of various animals in a state of
nature, when circumstances have been favorable to them during
two or three following seasons. Still more striking is the evi-
dence from our domestic animals of many kinds which have run
wild in several parts of the world; if the statements of the rate of
increase of slow-breeding cattle and horses in South America, and
latterly in Australia, had not been well authenticated, they would
have been incredible. So it is with plants; cases could be given
of introduced plants which have become common throughout
whole islands in a period of less than ten years. Several of

the plants, such as the cardoon and a tall thistle, which are
now the commonest over the wide plains of La Plata, clothing
square leagues of surface almost to the exclusion of every other
plant, have been introduced from Europe; and there are plants
which now range in India, as I hear from Falconer, from Cape
Comorin to the Himalaya, which have been imported from
America since its discovery. In such cases—and endless others
could be given-no one supposes that the fertility of the animals
or plants has been suddenly and temporarily increased in any
sensible degree. The obvious explanation is that the conditions.
of life have been highly favorable, and that there has conse-
quently been less destruction of the old and young, and that
nearly all the young have been enabled to breed.
Their geo-
metrical ratio of increase, the result of which never fails to be
surprising, simply explains their extraordinarily rapid increase
and wide diffusion in their new homes.
In a state of nature almost every full-grown plant annually
produces seed, and amongst animals there are very few which do
not annually pair. Hence we may confidently assert that all
plants and animals are tending to increase at a geometrical
ratio, that all would rapidly stock every station in which they
could anyhow exist,- and that this geometrical tendency to in-
crease must be checked by destruction at some period of life.
Our familiarity with the larger domestic animals tends, I think,
to mislead us: we see no great destruction falling on them, but
we do not keep in mind that thousands are annually slaughtered
for food, and that in a state of nature an equal number would
have somehow to be disposed of.
The only difference between organisms which annually pro-
duce eggs or seeds by the thousand, and those which produce
extremely few, is that the slow breeders would require a few
more years to people, under favorable conditions, a whole dis-
trict, let it be ever so large. The condor lays a couple of eggs
and the ostrich a score, and yet in the same country the condor
may be the more numerous of the two; the Fulmar petrel lays
but one egg, yet it is believed to be the most numerous bird in
the world. One fly deposits hundreds of eggs, and another, like
the hippobosca, a single one; but this difference does not deter-
mine how many individuals of the two species can be supported
in a district.
A large number of eggs is of some importance to
those species which depend on a fluctuating amount of food, for
――――

4419
it allows them rapidly to increase in number. But the real
importance of a large number of eggs or seeds is to make up for
much destruction at some period of life; and this period in the
great majority of cases is an early one. If an animal can in any
way protect its own eggs or young, a small number may be
produced, and yet the average stock be fully kept up; but if
many eggs or young are destroyed, many must be produced, or
the species will become extinct. It would suffice to keep up the
full number of a tree which lived on an average for a thousand
years, if a single seed were produced once in a thousand years,
supposing that this seed were never destroyed, and could be
insured to germinate in a fitting place. So that, in all cases, the
average number of any animal or plant depends only indirectly
on the number of its eggs or seeds.
In looking at nature, it is most necessary to keep the fore-
going considerations always in mind-never to forget that every
single organic being may be said to be striving to the utmost to
increase in numbers; that each lives by a struggle at some period
of its life; that heavy destruction inevitably falls either on the
young or old, during each generation or at recurrent intervals.
Lighten any check, mitigate the destruction ever so little, and
the number of the species will almost instantaneously increase to
any amount.
OF THE NATURE OF THE CHECKS TO INCREASE
From The Origin of Species >
THE
HE causes which check the natural tendency of each species.
to increase are most obscure. Look at the most vigorous
species: by as much as it swarms in numbers, by so much
will it tend to increase still further. We know not exactly
what the checks are, even in a single instance. Nor will this
surprise any one who reflects how ignorant we are on this
head, even in regard to mankind, although so incomparably bet-
ter known than any other animal. This subject of the checks to
increase has been ably treated by several authors, and I hope in
a future work to discuss it at considerable length, more especially
in regard to the feral animals of South America. Here I will
make only a few remarks, just to recall to the reader's mind some

CHARLES ROBERT DARWIN
of the chief points. Eggs or very young animals seem generally
to suffer most, but this is not invariably the case.
With plants
there is a vast destruction of seeds; but from some observations
which I have made, it appears that the seedlings suffer most,
from germinating in ground already thickly stocked with other
plants. Seedlings also are destroyed in vast numbers by various
enemies: for instance, on a piece of ground three feet long and
two wide, dug and cleared, and where there could be no choking
from other plants, I marked all the seedlings of our native weeds
as they came up, and out of 357 no less than 295 were destroyed,
chiefly by slugs and insects. If turf which has long been mown
-and the case would be the same with turf closely browsed by
quadrupeds-be let to grow, the more vigorous plants gradually
kill the less vigorous though fully grown plants; thus out of
twenty species growing on a little plot of mown turf (three feet
by four) nine species perished, from the other species being
allowed to grow up freely.
The amount of food for each species of course gives the ex-
treme limit to which each can increase; but very frequently it is
not the obtaining food, but the serving as prey to other animals,
which determines the average numbers of a species. Thus there
seems to be little doubt that the stock of partridges, grouse, and
hares in any large estate depends chiefly on the destruction of
vermin. If not one head of game were shot during the next
twenty years in England, and at the same time if no vermin
were destroyed, there would in all probability be less game than
at present, although hundreds of thousands of game animals are
now annually shot. On the other hand, in some cases, as with
the elephant, none are destroyed by beasts of prey; for even the
tiger in India most rarely dares to attack a young elephant pro-
tected by its dam.
Climate plays an important part in determining the average
numbers of a species, and periodical seasons of extreme cold or
drought seem to be the most effective of all checks. I estimated
(chiefly from the greatly reduced numbers of nests in the spring)
that the winter of 1854-5 destroyed four-fifths of the birds in my
own grounds; and this is a tremendous destruction, when we
remember that ten per cent. is an extraordinarily severe mor-
tality from epidemics with man. The action of climate seems at
first sight to be quite independent of the struggle for existence;
but in so far as climate chiefly acts in reducing food, it brings

on the most severe struggle between the individuals, whether of
the same or of distinct species, which subsist on the same kind
of food. Even when climate,- for instance, extreme cold,- acts
directly, it will be the least vigorous individuals, or those which
have got least food through the advancing winter, which will
suffer most.
When we travel from south to north, or from a damp region
to a dry, we invariably see some species gradually getting rarer
and rarer, and finally disappearing; and the change of climate
being conspicuous, we are tempted to attribute the whole effect
to its direct action. But this is a false view; we forget that
each species, even where it most abounds, is constantly suffering
enormous destruction at some period of its life, from enemies
or from competitors for the same place and food; and if these
enemies or competitors be in the least degree favored by any
slight change of climate, they will increase in numbers; and as
each area is already fully stocked with inhabitants, the other spe-
cies must decrease. When we travel southward and see a species
decreasing in numbers, we may feel sure that the cause lies quite
as much in other species being favored as in this one being hurt.
So it is when we travel northward; but in a somewhat lesser
degree, for the number of species of all kinds, and therefore of
competitors, decreases northward; hence in going northward, or
in ascending a mountain, we far oftener meet with stunted
forms, due to the directly injurious action of climate, than we
do in proceeding southward or in descending a mountain. When
we reach the arctic regions, or snow-capped summits, or abso-
lute deserts, the struggle for life is almost exclusively with the
elements.
That climate acts in main part indirectly by favoring other
species, we clearly see in the prodigious number of plants which
in our gardens can perfectly well endure our climate, but which
never become naturalized, for they cannot compete with our
native plants nor resist destruction by our native animals.
When a species, owing to highly favorable circumstances,
increases inordinately in numbers in a small tract, epidemics-
at least, this seems generally to occur with our game animals—
often ensue; and here we have a limiting check independent of
the struggle for life. But even some of these so-called epidemics
appear to be due to parasitic worms, which have from some
cause, possibly in part through facility of diffusion amongst the

crowded animals, been disproportionally favored: and here comes
in a sort of struggle between the parasite and its prey.
On the other hand, in many cases, a large stock of individ-
uals of the same species, relatively to the numbers of its ene-
mies, is absolutely necessary for its preservation. Thus we can
easily raise plenty of corn and rape-seed, etc. , in our fields,
because the seeds are in great excess compared with the number
of birds which feed on them; nor can the birds, though having
a superabundance of food at this one season, increase in number
proportionally to the supply of seed, as their numbers are checked.
during winter; but any one who has tried, knows how trouble-
some it is to get seed from a few wheat or other such plants in
a garden: I have in this case lost every single seed. This view
of the necessity of a large stock of the same species for its
preservation, explains I believe some singular facts in nature,
such as that of very rare plants being sometimes extremely
abundant in the few spots where they do exist; and that of
some social plants being social, that is, abounding in individuals,
even on the extreme verge of their range.
For in such cases,
we may believe that a plant could exist only where the condi-
tions of its life were so favorable that many could exist together
and thus save the species from utter destruction. I should add
that the good effects of inter-crossing, and the ill effects of close
inter-breeding, no doubt come into play in many of these cases;
but I will not here enlarge on this subject.
THE COMPLEX RELATIONS OF ALL ANIMALS AND PLANTS
TO EACH OTHER IN THE STRUGGLE FOR EXISTENCE
From the Origin of Species >
M
ANY cases are on record, showing how complex and unex-
pected are the checks and relations between organic beings
which have to struggle together in the same country.
I will give only a single instance, which though a simple one
interested me. In Staffordshire, on the estate of a relation
where I had ample means of investigation, there was a large
and extremely barren heath which had never been touched by
the hand of man; but several hundred acres of exactly the
same nature had been inclosed twenty-five years previously

and planted with Scotch fir. The change in the native vege-
tation of the planted part of the heath was most remarkable,
more than is generally seen in passing from one quite differ-
ent soil to another: not only the proportional numbers of the
heath-plants were wholly changed, but twelve species of plants
(not counting grasses and carices) flourished in the plantations,
which could not be found on the heath. The effect on the
insects must have been still greater, for six insectivorous birds
were very common in the plantations which were not to be
seen on the heath; and the heath was frequented by two or
three distinct insectivorous birds. Here we see how potent has
been the effect of the introduction of a single tree, nothing
whatever else having been done, with the exception of the land
having been inclosed so that cattle could not enter.
But how important an element inclosure is, I plainly saw near
Farnham in Surrey. Here there are extensive heaths with a
few clumps of old Scotch firs on the distant hill-tops: within the
last ten years large spaces have been inclosed, and self-sown
firs are now springing up in multitudes, so close together that
all cannot live. When I ascertained that these young trees had
not been sown or planted, I was so much surprised at their
numbers that I went to several points of view, whence I could
examine hundreds of acres of the uninclosed heath, and literally
I could not see a single Scotch fir except the old planted clumps.
But on looking closely between the stems of the heath, I found
a multitude of seedlings and little trees which had been perpetu-
ally browsed down by the cattle. In one square yard, at a
point some hundred yards distant from one of the old clumps,
I counted thirty-two little trees; and one of them, with twenty-
six rings of growth, had during many years tried to raise its
head above the stems of the heath, and had failed. No wonder
that as soon as the land was inclosed it became thickly clothed
with vigorously growing young firs. Yet the heath was SO
extremely barren and so extensive that no one would ever
have imagined that cattle would have so closely and effectually
searched it for food.
Here we see that cattle absolutely determine the existence of
the Scotch fir; but in several parts of the world insects deter-
mine the existence of cattle. Perhaps Paraguay offers the most
curious instance of this; for here neither cattle nor horses nor
dogs have ever run wild, though they swarm southward and

northward in a feral state; and Azara and Rengger have shown
that this is caused by the greater number in Paraguay of a cer-
tain fly, which lays its eggs in the navels of these animals when
first born. The increase of these flies, numerous as they are,
must be habitually checked by some means, probably by other
parasitic insects. Hence if certain insectivorous birds were to de-
crease in Paraguay, the parasitic insects would probably increase;
and this would lessen the number of the navel-frequenting
flies; then cattle and horses would become feral, and this would
certainly greatly alter (as indeed I have observed in parts of
South America) the vegetation; this again would largely affect
the insects; and this, as we have just seen in Staffordshire, the
insectivorous birds,-- and so onwards in ever increasing circles of
complexity. Not that under nature the relations will ever be as
simple as this. Battle within battle must be continually recur-
ring with varying success; and yet in the long run the forces
are so nicely balanced that the face of nature remains for long
periods of time uniform, though assuredly the merest trifle would
give the victory to one organic being over another. Neverthe-
less, so profound is our ignorance and so high our presumption,
that we marvel when we hear of the extinction of an organic
being; and as we do not see the cause, we invoke cataclysms to
desolate the world, or invent laws on the duration of the forms
of life!
OF NATURAL SELECTION; OR THE SURVIVAL OF THE FITTEST
From the Origin of Species'
SEVE
EVERAL writers have misapprehended or objected to the term
Natural Selection. Some have even imagined that Natural
Selection induces variability, whereas it implies only the
preservation of such variations as arise and are beneficial to the
being under its conditions of life. No one objects to agricultur-
ists speaking of the potent effects of man's selection; and in this
case the individual differences given by nature, which man for
some object selects, must of necessity first occur. Others have
objected that the term selection implies conscious choice in the
animals which become modified; and it has even been urged that
as plants have no volition, Natural Selection is not applicable to
L

them! In the literal sense of the word, no doubt, Natural Selec-
tion is a false term; but who ever objected to chemists speaking
of the elective affinities of the various elements? -and yet an
acid cannot strictly be said to elect the base with which it in
preference combines. It has been said that I speak of Natural
Selection as an active power or Deity; but who objects to an
author speaking of the attraction of gravity as ruling the move-
ments of the planets? Every one knows what is meant and is
implied by such metaphorical expressions; and they are almost
necessary for brevity. So again it is difficult to avoid personify-
ing the word Nature; but I mean by nature only the aggregate
action and product of many natural laws, and by laws the
sequence of events as ascertained by us. With a little famil-
iarity such superficial objections will be forgotten.
We shall best understand the probable course of Natural
Selection by taking the case of a country undergoing some slight
physical change; for instance, of climate. The proportional num-
bers of its inhabitants will almost immediately undergo a change,
and some species will probably become extinct. We may con-
clude, from what we have seen of the intimate and complex
manner in which the inhabitants of each country are bound
together, that any change in the numerical proportions of the
inhabitants, independently of the change of climate itself, would
seriously affect the others. If the country were open on its bor-
ders, new forms would certainly immigrate, and this would
likewise seriously disturb the relations of some of the former
inhabitants. Let it be remembered how powerful the influence
of a single introduced tree or mammal has been shown to be.
But in the case of an island, or of a country partly surrounded
by barriers, into which new and better adapted forms could not
freely enter, we should then have places in the economy of
nature which would assuredly be better filled up if some of the
original inhabitants were in some manner modified; for had the
area been open to immigration, these same places would have
been seized on by intruders. In such cases, slight modifications
which in any way favored the individuals of any species by bet-
ter adapting them to their altered conditions, would tend to be
preserved; and Natural Selection would have free scope for the
work of improvement.
We have good reason to believe, as shown in the first chap-
ter, that changes in the conditions of life give a tendency to

CHARLES ROBERT DARWIN
increased variability; and in the foregoing cases the conditions
have changed, and this would manifestly be favorable to Natural
Selection by affording a better chance of the occurrence of prof-
itable variations. Unless such occur, Natural Selection can do
nothing. Under the term of "variations," it must never be for-
gotten that mere individual differences are included. As man
can produce a great result with his domestic animals and plants
by adding up in any given direction individual differences, so
could Natural Selection, but far more easily from having incom-
parably longer time for action. Nor do I believe that any great
physical change, as of climate, or any unusual degree of isola-
tion to check immigration, is necessary in order that new and
unoccupied places should be left, for Natural Selection to fill up
by improving some of the varying inhabitants. For as all the
inhabitants of each country are struggling together with nicely
balanced forces, extremely slight modifications in the structure or
habits of one species would often give it an advantage over
others; and still further modifications of the same kind would
often still further increase the advantage, as long as the species
continued under the same conditions of life and profited by sim-
ilar means of subsistence and defense. No country can be
named, in which all the native inhabitants are now so perfectly
adapted to each other and to the physical conditions under which
they live, that none of them could be still better adapted or im-
proved; for in all countries the natives have been so far con-
quered by naturalized productions that they have allowed some
foreigners to take firm possession of the land. And as foreign-
ers have thus in every country beaten some of the natives, we
may safely conclude that the natives might have been modified
with advantage, so as to have better resisted the intruders.
As man can produce, and certainly has produced, a great
result by his methodical and unconscious means of selection, what
may not Natural Selection effect? Man can act only on external
and visible characters; Nature, if I may be allowed to personify
the natural preservation or survival of the fittest, cares nothing
for appearances, except in so far as they are useful to any being.
She can act on every internal organ, on every shade of constitu-
tional difference, on the whole machinery of life. Man selects
only for his own good; Nature only for that of the being which
she tends. Every selected character is fully exercised by her, as
is implied by the fact of their selection. Man keeps the natives

of many climates in the same country: he seldom exercises each
selected character in some peculiar and fitting manner; he feeds
a long and a short-beaked pigeon on the same food; he does not
exercise a long-backed or long-legged quadruped in any peculiar
manner; he exposes sheep with long and short wool to the same
climate. He does not allow the most vigorous males to struggle
for the females. He does not rigidly destroy all inferior animals,
but protects during each varying season, as far as lies in his
power, all his productions. He often begins his selection by some
half-monstrous form; or at least by some modification prominent
enough to catch the eye or to be plainly useful to him. Under
Nature, the slightest differences of structure or constitution may
well turn the nicely balanced scale in the struggle for life, and
so be preserved. How fleeting are the wishes and efforts of
man! How short his time, and consequently how poor will be
his results, compared with those accumulated by Nature during
whole geological periods! Can we wonder then that Nature's
productions should be far "truer" in character than man's pro-
ductions; that they should be infinitely better adapted to the most
complex conditions of life, and should plainly bear the stamp of
far higher workmanship?
It may metaphorically be said that Natural Selection is daily
and hourly scrutinizing, throughout the world, the slightest varia-
tions; rejecting those that are bad, preserving and adding up all
that are good; silently and insensibly working, whenever and
wherever opportunity offers, at the improvement of each organic
being in relation to its organic and inorganic conditions of life.
We see nothing of these slow changes in progress until the hand
of time has marked the lapse of ages, and then so imperfect is
our view into long-past geological ages, that we see only that the
forms of life are now different from what they formerly were.
In order that any great amount of modification should be
effected in a species, a variety when once formed must again,
perhaps after a long interval of time, vary or present individual
differences of the same favorable nature as before; and these
must be again preserved, and so onward step by step. Seeing
that individual differences of the same kind perpetually recur,
this can hardly be considered as an unwarrantable assumption.
But whether it is true, we can judge only by seeing how far the
hypothesis accords with and explains the general phenomena of
nature. On the other hand, the ordinary belief that the amount

4428
CHARLES ROBERT DARWIN
of possible variation is a strictly limited quantity, is likewise a
simple assumption.
Although Natural Selection can act only through and for the
good of each being, yet characters and structures, which we are
apt to consider as of very trifling importance, may thus be acted
on. When we see leaf-eating insects green, and bark-feeders
mottled gray; the Alpine ptarmigan white in winter, the red
grouse the color of heather,- we must believe that these tints
are of service to these birds and insects in preserving them from
danger. Grouse, if not destroyed at some period of their lives,
would increase in countless numbers; they are known to suffer
largely from birds of prey; and hawks are guided by eyesight to
their prey - so much so, that on parts of the Continent persons
are warned not to keep white pigeons, as being the most liable
to destruction. Hence Natural Selection might be effective in
giving the proper color to each kind of grouse, and in keeping
that color, when once acquired, true and constant.
Nor ought
we to think that the occasional destruction of an animal of any
particular color would produce little effect: we should remember
how essential it is in a flock of white sheep to destroy a lamb
with the faintest trace of black. We have seen how the color
of hogs which feed on the "paint-root" in Virginia, determines
whether they shall live or die. In plants, the down on the
fruit and the color of the flesh are considered by botanists as
characters of the most trifling importance; yet we hear from
an excellent horticulturist, Downing, that in the United States
smooth-skinned fruits suffer far more from a beetle, a curculio,
than those with down; that purple plums suffer far more from a
certain disease than yellow plums; whereas another disease attacks
yellow-fleshed peaches far more than those with other colored
flesh. If with all the aids of art, these slight differences make a
great difference in cultivating the several varieties, assuredly, in
a state of nature, where the trees would have to struggle with
other trees and with a host of enemies, such differences would
effectually settle which variety, whether a smooth or downy, a
yellow or a purple-fleshed fruit, should succeed.
In looking at many small points of difference between species,
which, as far as our ignorance permits us to judge, seem quite
unimportant, we must not forget that climate, food, etc. , have no
doubt produced some direct effect. It is also necessary to bear
in mind that owing to the law of correlation, when one part
----

4429
varies, and the variations are accumulated through Natural
Selection, other modifications, often of the most unexpected
nature, will ensue.
As we see that those variations which under domestication
appear at any particular period of life, tend to reappear in the
offspring at the same period; -for instance, in the shape, size,
and flavor of the seeds of the many varieties of our culinary and
agricultural plants; in the caterpillar and cocoon stages of the
varieties of the silkworm; in the eggs of poultry, and in the
color of the down of their chickens; in the horns of our sheep and
cattle when nearly adult; so in a state of nature Natural
Selection will be enabled to act on and modify organic beings at
any age, by the accumulation of variations profitable at that age,
and by their inheritance at a corresponding age.
If it profit a
plant to have its seeds more and more widely disseminated by
the wind, I can see no greater difficulty in this being effected
through Natural Selection, than in the cotton-planter increasing
and improving by selection the down in the pods on his cotton-
trees. Natural Selection may modify and adapt the larva of an
insect to a score of contingencies wholly different from those
which concern the mature insect; and these modifications may
effect, through correlation, the structure of the adult. So, con-
versely, modifications in the adult may affect the structure of the
larva; but in all cases Natural Selection will insure that they
shall not be injurious: for if they were so, the species would
become extinct.
Natural Selection will modify the structure of the young in
relation to the parent, and of the parent in relation to the
young. In social animals it will adapt the structure of each
individual for the benefit of the whole community, if the com-
munity profits by the selected change. What Natural Selection
cannot do, is to modify the structure of one species, without
giving it any advantage, for the good of another species; and
though statements to this effect may be found in works of nat-
ural history, I cannot find one case which will bear investigation.
A structure used only once in an animal's life, if of high import-
ance to it, might be modified to any extent by Natural Selection;
for instance, the great jaws possessed by certain insects, used
exclusively for opening the cocoon, or the hard tip to the beak
of unhatched birds, used for breaking the eggs. It has been
asserted that of the best short-beaked tumbler-pigeons a greater

CHARLES ROBERT DARWIN
number perish in the egg than are able to get out of it; so that
fanciers assist in the act of hatching. Now if Nature had
to make the beak of a full-grown pigeon very short for the
bird's own advantage, the process of modification would be very
slow, and there would be simultaneously the most rigorous selec-
tion of all the young birds within the egg, which had the most
powerful and hardest beaks, for all with weak beaks would inev-
itably perish; or more delicate and more easily broken shells
might be selected, the thickness of the shell being known to
vary like every other structure.
It may be well here to remark that with all beings there
must be much fortuitous destruction, which can have little or no
influence on the course of Natural Selection. For instance, a vast
number of eggs or seeds are annually devoured, and these could
be modified through Natural Selection only if they varied in
some manner which protected them from their enemies. Yet
many of these eggs or seeds would perhaps, if not destroyed,
have yielded individuals better adapted to their conditions of life
than any of those which happened to survive. So again a vast
number of mature animals and plants, whether or not they be
the best adapted to their conditions, must be annually destroyed
by accidental causes, which would not be in the least degree miti-
gated by certain changes of structure or constitution which would
in other ways be beneficial to the species. But let the destruc-
tion of the adults be ever so heavy, if the number which can
exist in any district be not wholly kept down by such causes,
or again, let the destruction of eggs or seeds be so great that
only a hundredth or a thousandth part are developed, yet of
those which do survive, the best adapted individuals, supposing
that there is any variability in a favorable direction, will tend
to propagate their kind in larger numbers than the less well
adapted. If the numbers be wholly kept down by the causes
just indicated, as will often have been the case, Natural Selection
will be powerless in certain beneficial directions; but this is no
valid objection to its efficiency at other times and in other ways;
for we are far from having any reason to suppose that many
species ever undergo modification and improvement at the same
time in the same area.

PROGRESSIVE CHANGE COMPARED WITH INDEPENDENT
CREATION
From the Origin of Species >
A
UTHORS of the highest eminence seem to be fully satisfied
with the view that each species has been independently
created. To my mind it accords better with what we know
of the laws impressed on matter by the Creator, that the pro-
duction and extinction of the past and present inhabitants of the
world should have been due to secondary causes, like those
determining the birth and death of an individual. When I view
all beings not as special creations, but as the lineal descendants
of some few beings which lived long before the first bed of
the Cambrian system was deposited, they seem to me to become
ennobled. Judging from the past, we may safely infer that not
one living species will transmit its unaltered likeness to a distant
futurity. And of the species now living, very few will transmit
progeny of any kind to a far distant futurity; for the manner in
which all organic beings are grouped shows that the greater
number of species in each genus, and all the species in many
genera, have left no descendants, but have become utterly extinct.
We can so far take a prophetic glance into futurity as to foretell
that it will be the common and widely spread species, belonging
to the larger and dominant groups within each class, which will
ultimately prevail and procreate new and dominant species. As
all the living forms of life are the lineal descendants of those
which lived long before the Cambrian epoch, we may feel certain
that the ordinary succession by generation has never once been
broken, and that no cataclysm has desolated the whole world.
Hence we may look with some confidence to a secure future of
great length. And as Natural Selection works solely by and for
the good of each being, all corporeal and mental endowments
will tend to progress towards perfection.
It is interesting to contemplate a tangled bank, clothed with
many plants of many kinds, with birds singing on the bushes,
with various insects flitting about, and with worms crawling
through the damp earth, and to reflect that these elaborately
constructed forms, so different from each other, and dependent
upon each other in so complex a manner, have all been produced
by laws acting around us. These laws, taken in the largest

sense, being Growth with Reproduction; Inheritance, which is
almost implied by reproduction; Variability from the indirect and
direct action of the conditions of life, and from use and disuse:
a Ratio of Increase so high as to lead to a Struggle for Life,
and as a consequence to Natural Selection, entailing Divergence
of Character and the Extinction of less-improved forms. Thus
from the war of nature, from famine and death, the most exalted
object which we are capable of conceiving,- namely, the produc-
tion of the higher animals,- directly follows. There is grandeur
in this view of life, with its several powers, having been origi
nally breathed by the Creator into a few forms or into one; and
that whilst this planet has gone cycling on according to the fixed
law of gravity, from so simple a beginning endiess forms most
beautiful and most wonderful have been and are being evolved.
CREATIVE DESIGN
From The Variation of Animals and Plants under Domestication >
S
SOME authors have declared that natural selection explains
nothing, unless the precise cause of each slight individual
difference be made clear. If it were explained to a savage
utterly ignorant of the art of building, how the edifice had been
raised stone upon stone, and why wedge-formed fragments were
used for the arches, flat stones for the roof, etc. ; and if the use
of each part and of the whole building were pointed out, it would
be unreasonable if he declared that nothing had been made clear
to him, because the precise cause of the shape of each fragment
could not be told. But this is a nearly parallel case with the
objection that selection explains nothing, because we know not
the cause of each individual difference in the structure of each
being.
The shape of the fragments of stone at the base of our
precipice may be called accidental, but this is not strictly correct;
for the shape of each depends on a long sequence of events, all
obeying natural laws: on the nature of the rock, on the lines of
deposition or cleavage, on the form of the mountain, which
depends on its upheaval and subsequent denudation, and lastly
on the storm or earthquake which throws down the fragments.
But in regard to the use to which the fragments may be put,
their shape may be strictly said to be accidental. And here we

are led to face a great difficulty, in alluding to which I
aware that I am traveling beyond my proper province. An
omniscient Creator must have foreseen every consequence which
results from the laws imposed by him. But can it be reasonably
maintained that the Creator intentionally ordered, if we use the
words in any ordinary sense, that certain fragments of rock
should assume certain shapes so that the builder might erect his
edifice? If the various laws which have determined the shape of
each fragment were not predetermined for the builder's sake, can
it be maintained with any greater probability that he specially
ordained for the sake of the breeder each of the innumerable
variations in our domestic animals and plants; many of these
variations being of no service to man, and not beneficial, far
more often injurious, to the creatures themselves? Did he ordain
that the crop and tail-feathers of the pigeon should vary, in
order that the, fancier might make his grotesque pouter and fan-
tail breeds? Did he cause the frame and mental qualities of the
dog to vary in order that a breed might be formed of indomi-
table ferocity, with jaws fitted to pin down the bull for man's
brutal sport? But if we give up the principle in one case,—if
we do not admit that the variations of the primeval dog were
intentionally guided in order that the greyhound, for instance,
that perfect image of symmetry and vigor, might be formed,—
no shadow of reason can be assigned for the belief that varia-
tions, alike in nature and the result of the same general laws,
which have been the groundwork through natural selection of the
formation of the most perfectly adapted animals in the world,
man included, were intentionally and specially guided. How-
ever much we may wish it, we can hardly follow Professor Asa
Gray in his belief that "variation has been led along certain
beneficial lines," like a stream «< along definite and useful lines of
irrigation. " If we
assume that each particular variation was
from the beginning of all time preordained, then that plasticity
of organization which leads to many injurious deviations of
structure, as well as the redundant power of reproduction which
inevitably leads to a struggle for existence, and as a conse-
quence, to the natural selection or survival of the fittest,- must
appear to us superfluous laws of Nature. On the other hand, an
omnipotent and omniscient Creator ordains everything and fore-
sees everything. Thus we are brought face to face with a diffi-
culty as insoluble as is that of free-will and predestination.

THE ORIGIN OF THE HUMAN SPECIES
From The Descent of Man'
THE
HE main conclusion arrived at in this work-namely, that
man is descended from some lowly organized form-will, I
regret to think, be highly distasteful to many persons. But
there can hardly be a doubt that we are descended from barba-
rians. The astonishment which I felt on first seeing a party of
Fuegians on a wild and broken shore will never be forgotten by
me, for the reflection at once rushed into my mind - Such were
our ancestors. These men were absolutely naked and bedaubed
with paint. . They possessed hardly any arts, and like wild
animals, lived on what they could catch; they had no government,
and were merciless to every one not of their own small tribe.
He who has seen a savage in his native land will not feel much
shame if forced to acknowledge that the blood of some more
humble creature flows in his veins. For my own part, I would
as soon be descended from that heroic little monkey who braved
his dreaded enemy in order to save the life of his keeper; or
from that old baboon who, descending from the mountains, car-
ried away in triumph his young comrade from a crowd of as-
tonished dogs, -as from a savage who delights to torture his
enemies, offers up bloody sacrifices, practices infanticide without
remorse, treats his wives like slaves, knows no decency, and is
haunted by the grossest superstitions.
Man may be excused for feeling some pride at having risen,
though not through his own exertions, to the very summit of the
organic scale; and the fact of his having thus risen, instead of
having been aboriginally placed there, may give him hopes for a
still higher destiny in the distant future. But we are not here
concerned with hopes or fears, only with the truth as far as our
reason allows us to discover it. I have given the evidence to the
best of my ability; and we must acknowledge, as it seems to
me, that Man with all his noble qualities, with sympathy which
feels for the most debased, with benevolence which extends not
only to other men but to the humblest living creature, with his
godlike intellect which has penetrated into the movements and
constitution of the solar system, with all these exalted powers,
Man still bears in his bodily frame the indelible stamp of his
lowly origin.

ALPHONSE DAUDET
(1840-)
BY AUGUSTIN FILON
ORTY years have now elapsed since a lad of seventeen, shiv-
ering under his light summer dress in a cold misty morn-
ing, was waiting, with an empty stomach, for the opening
of a « dairy
» in the Quartier Latin. Young as he was, he looked
still younger: a pale, eager, intellectual face, with flashing eyes, del-
icately
carved features, and a virgin forest of dark hair falling low
on his brow. He had been an usher for a twelvemonth at a small
college in the South of France, and he had just arrived in Paris
after a two-days' journey in a third-class railway carriage, during
which time he had tasted no food and no drink except a few drops
of brandy from the flask of some charitable sailors.
