a fallacy。
They come again and again; like tunes in a barrel…organ。 Therefore
Darwin's theory is a fallacy。
Hallam made a mistake; and in his History of the Middle Ages; p。 398;
he corrects himself。 Therefore Darwin's theory is wrong。
Dr。 Darwin in the last century said the same thing as his son or
grandson says nowwill the writer of the article refer to anything
bearing on natural selection and the struggle for existence in Dr。
Darwin's work?and a foolish nobleman said something foolish about
monkey's tails。 Therefore Darwin's theory is wrong。
Giordano Bruno was burnt in the year 1600 A。D。; he was a Pantheist;
therefore Darwin's theory is wrong。
And finally; as a clinching argument; in one of the neighbouring
settlements there is a barrel…organ which plays its psalm tunes in
the middle of its jigs and waltzes。 After this all lingering doubts
concerning the falsehood of Darwin's theory must be at an end; and
any person of ordinary common sense must admit that the theory of
development by natural selection is unwarranted by experience and
reason。
The articles conclude with an implied statement that Darwin supposes
the Polar bear to swim about catching flies for so long a period that
at last it gets the fins it wishes for。
Now; however sceptical I may yet feel about the truth of all Darwin's
theory; I cannot sit quietly by and see him misrepresented in such a
scandalously slovenly manner。 What Darwin does say is that sometimes
diversified and changed habits may be observed in individuals of the
same species; that is that there are eccentric animals just as there
are eccentric men。 He adduces a few instances and winds up by saying
that 〃in North America the black bear was seen by Hearne swimming for
hours with widely open mouth; thus catchingalmost like a whale
insects in the water。〃 This and nothing more。 (See pp。 201 and
202。)
Because Darwin says that a bear of rather eccentric habits happened
to be seen by Hearne swimming for hours and catching insects almost
like a whale; your writer (with a carelessness hardly to be
reprehended in sufficiently strong terms) asserts by implication that
Darwin supposes the whale to be developed from the bear by the latter
having had a strong desire to possess fins。 This is disgraceful。
I can hardly be mistaken in supposing that I have quoted the passage
your writer alludes to。 Should I be in error; I trust he will give
the reference to the place in which Darwin is guilty of the nonsense
that is fathered upon him in your article。
It must be remembered that there have been few great inventions in
physics or discoveries in science which have not been foreshadowed to
a certain extent by speculators who were indeed mistaken; but were
yet more or less on the right scent。 Day is heralded by dawn; Apollo
by Aurora; and thus it often happens that a real discovery may wear
to the careless observer much the same appearance as an exploded
fallacy; whereas in fact it is widely different。 As much caution is
due in the rejection of a theory as in the acceptation of it。 The
first of your writers is too hasty in accepting; the second in
refusing even a candid examination。
Now; when the Saturday Review; the Cornhill Magazine; Once a Week;
and Macmillan's Magazine; not to mention other periodicals; have
either actually and completely as in the case of the first two;
provisionally as in the last mentioned; given their adherence to the
theory in question; it may be taken for granted that the arguments in
its favour are sufficiently specious to have attracted the attention
and approbation of a considerable number of well…educated men in
England。 Three months ago the theory of development by natural
selection was openly supported by Professor Huxley before the British
Association at Cambridge。 I am not adducing Professor Huxley's
advocacy as a proof that Darwin is right (indeed; Owen opposed him
tooth and nail); but as a proof that there is sufficient to be said
on Darwin's side to demand more respectful attention than your last
writer has thought it worth while to give it。 A theory which the
British Association is discussing with great care in England is not
to be set down by off…hand nicknames in Canterbury。
To those; however; who do feel an interest in the question; I would
venture to give a word or two of advice。 I would strongly deprecate
forming a hurried opinion for or against the theory。 Naturalists in
Europe are canvassing the matter with the utmost diligence; and a few
years must show whether they will accept the theory or no。 It is
plausible; that can be decided by no one。 Whether it is true or no
can be decided only among naturalists themselves。 We are outsiders;
and most of us must be content to sit on the stairs till the great
men come forth and give us the benefit of their opinion。

Your obedient servant;

DARWIN ON SPECIES: 'From the Press; March 14th; 1863。'
To the Editor of the Press。
SirA correspondent signing himself 〃A。 M。〃 in the issue of February
21st says: 〃Will the writer (of an article on barrel…organs) refer
to anything bearing upon natural selection and the struggle for
existence in Dr。 Darwin's work?〃 This is one of the trade forms by
which writers imply that there is no such passage; and yet leave a
loophole if they are proved wrong。 I will; however; furnish him with
a passage from the notes of Darwin's Botanic Garden:…
〃I am acquainted with a philosopher who; contemplating this subject;
thinks it not impossible that the first insects were anthers or
stigmas of flowers; which had by some means loosed themselves from
their parent plant; and that many insects have gradually in long
process of time been formed from these; some acquiring wings; others
fins; and others claws; from their ceaseless efforts to procure their
food or to secure themselves from injury。 The anthers or stigmas are
therefore separate beings。〃
This passage contains the germ of Mr。 Charles Darwin's theory of the
origin of species by natural selection:…
〃Analogy would lead me to the belief that all animals and plants have
descended from one prototype。〃
Here are a few specimens; his illustrations of the theory:…
〃There seems to me no great difficulty in believing that natural
selection has actually converted a swim…bladder into a lung or organ
used exclusively for respiration。〃 〃A swim…bladder has apparently
been converted into an air…breathing lung。〃 〃We must be cautious in
concluding that a bat could not have been formed by natural selection
from an animal which at first could only glide through the air。〃 〃I
can see no insuperable difficulty in further believing it possible
that the membrane…connected fingers and forearm of the galeopithecus
might be greatly lengthened by natural selection; and this; as far as
the organs of flight are concerned; would convert it into a bat。〃
〃The framework of bones being the same in the hand of a man; wing of
a bat; fin of a porpoise; and leg of a horse; the same number of
vertebrae forming the neck of the giraffe and of the elephant; and
innumerable other such facts; at once explain themselves on the
theory of descent with slow and slight successive modifications。〃
I do not mean to go through your correspondent's letter; otherwise 〃I
could hardly reprehend in sufficiently strong terms〃 (and all that
sort of thing) the perversion of what I said about Giordano Bruno。
But 〃ex uno disce omnes〃I am; etc。;
〃THE SAVOYARD。〃
DARWIN ON SPECIES: 'From the Press; 18 March; 1863。'
To the Editor of the Press。
SirThe 〃Savoyard〃 of last Saturday has shown that he has perused
Darwin's Botanic Garden with greater attention than myself。 I am
obliged to him for his correction of my carelessness; and have not
the smallest desire to make use of any loopholes to avoid being
〃proved wrong。〃 Let; then; the 〃Savoyard's〃 assertion that Dr。
Darwin had to a certain extent forestalled Mr。 C。 Darwin stand; and
let my implied denial that in the older Darwin's works passages
bearing on natural selection; or the struggle for existence; could be
found; go for nought; or rather let it be set down against me。
What follows? Has the 〃Savoyard〃 (supposing him to be the author of
the article on barrel…organs) adduced one particle of real argument
the more to show that the real Darwin's theory is wrong?
The elder Darwin writes in a note that 〃he is acquainted with a
philosopher who thinks it not impossible that the first insects were
the anthers or stigmas of flowers; which by some means; etc。 etc。〃
This is mere speculation; not a definite theory; and though the
passage above as quoted by the〃 Savoyard〃 certainly does contain the
germ of Darwin's theory; what is it more than the crudest and most
unshapen germ? And in what conceivable way does this discovery of
the egg invalidate the excellence of the chicken?
Was there ever a great theory yet which was not more or less
developed from previous speculations which were all to a certain
extent wrong; and all ridiculed; perhaps not undeservedly; at the
time of their appearance? There is a wide difference between a
speculation and a theory。 A speculation involves the notion of a man
climbing into a lofty position; and descrying a somewhat remote
object which he cannot fully make out。 A theory implies that the
theorist has looked long and steadfastly till he is clear in his own
mind concerning the nature of the thing which he is beholding。 I
submit that the 〃Savoyard〃 has unfairly made use of the failure of
certain speculations in order to show that a distinct theory is
untenable。
Let it be granted that Darwin's theory has been foreshadowed by
numerous previous writers。 Grant the 〃Savoyard〃 his Giordano Bruno;
and give full weight to the barrel…organ in a neighbouring
settlement; I would still ask; has the theory of natural development
of species ever been placed in anything approaching its present clear
and connected form before the appearance of Mr。 Darwin's book? Has
it ever received the full attention of the scientific world as a duly
organised theory; one presented in a tangible shape and demanding
