,the ,darwinian ,hypothesis99 by
,thomas ,h4 ,huxley ,,darwin ,,on
,,the ,,origin ,,of ,,species4
,,there is a growing immensity in the
speculations of science to which no
human thing or thought at this day is
comparable4 ,apart from the results
which science brings us home and
securely harvests1 there is an
expansive force and latitude in its
tentative efforts1 which lifts us out
of ourselves and transfigures our
mortality4 ,we may have a preference
for moral themes1 like the ,homeric
sage1 who had seen and known much3--
8,cities of men ,and manners1
climates1 councils1 governments02 yet
we must end by confession that
8,the windy ways of men ,are but
dust which rises up ,and is
lightly laid again10 in comparison
with the work of nature1 to which
science testifies1 but which has no
boundaries in time or space to which
science can approximate4 ,there is
something altogether out of the reach of
science1 and yet the compass of
science is practically illimitable4
,hence it is that from time to time we
are startled and perplexed by theories
which have no parallel in the
contracted moral world2 for the
generalizations of science sweep on in
ever-widening circles1 and more aspiring
flights1 through a limitless creation4
,while astronomy1 with its telescope1
ranges beyond the known stars1 and
physiology1 with its microscope1 is
subdividing infinite minutiae1 we may
expect that our historic centuries may
be treated as inadequate counters in the
history of the planet on which we are
placed4 ,we must expect new conceptions
of the nature and relations of its
denizens1 as science acquires the
materials for fresh generalizations2
nor have we occasion for alarms if a
highly advanced knowledge1 like that of
the eminent ,naturalist before us1
confronts us with an hypothesis as vast
as it is novel4 ,this hypothesis may or
may not be sustainable hereafter2 it
may give way to something else1 and
higher science may reverse what science
has here built up with so much skill
and patience1 but its sufficiency must
be tried by the tests of science alone1
if we are to maintain our position as
the heirs of ,bacon and the acquitters
of ,galileo4 ,we must weigh this
hypothesis strictly in the controversy
which is coming1 by the only tests
which are appropriate1 and by no others
whatsoever4 ,the hypothesis to which
we point1 and of which the present work
of ,mr4 ,darwin is but the preliminary
outline1 may be stated in his own
language as follows3--8,species
originated by means of natural
selection1 or through the preservation
of the favoured races in the struggle
for life40 ,to render this thesis
intelligible1 it is necessary to
interpret its terms4 ,in the first
place1 what is a species8 ,the question
is a simple one1 but the right answer
to it is hard to find1 even if we
appeal to those who should know most
about it4 ,it is all those animals or
plants which have descended from a
single pair of parents2 it is the
smallest distinctly definable group of
living organisms2 it is an eternal and
immutable entity2 it is a mere
abstraction of the human intellect
having no existence in nature4 ,such are
a few of the significations attached
to this simple word which may be culled
from authoritative sources2 and if1
leaving terms and theoretical subtleties
aside1 we turn to facts and endeavour
to gather a meaning for ourselves1 by
studying the things to which1 in
practice1 the name of species is
applied1 it profits us little4 ,for
practice varies as much as theory4 ,let
the botanist or the zoologist examine
and describe the productions of a
country1 and one will pretty certainly
disagree with the other as to the
number1 limits1 and definitions of the
species into which he groups the very
same things4 ,in these islands1 we are
in the habit of regarding mankind as of
one species1 but a fortnight's steam
will land us in a country where divines
and savants1 for once in agreement1 vie
with one another in loudness of
assertion1 if not in cogency of proof1
that men are of different species2 and1
more particularly1 that the species
negro is so distinct from our own that
the ,ten ,commandments have actually no
reference to him4 ,even in the calm
region of entomology1 where1 if anywhere
in this sinful world1 passion and
prejudice should fail to stir the mind1
one learned coleopterist will fill ten
attractive volumes with descriptions of
species of beetles1 nine-tenths of which
are immediately declared by his
brother beetle-mongers to be no species
at all4 ,the truth is that the number
of distinguishable living creatures
almost surpasses imagination4 ,at least
a hundred thousand such kinds of
insects alone have been described and
may be identified in collections1 and
the number of separable kinds of living
things is underestimated at half a
million4 ,seeing that most of these
obvious kinds have their accidental
varieties1 and that they often shade
into others by imperceptible degrees1
it may well be imagined that the task of
distinguishing between what is
permanent and what fleeting1 what is a
species and what a mere variety1 is
sufficiently formidable4 ,but is it
not possible to apply a test whereby a
true species may be known from a mere
variety8 ,is there no criterion of
species8 ,great authorities affirm that
there is--that the unions of members of
the same species are always fertile1
while those of distinct species are
either sterile1 or their offspring1
called hybrids1 are so4 ,it is affirmed
not only that this is an experimental
fact1 but that it is a provision for
the preservation of the purity of
species4 ,such a criterion as this
would be invaluable2 but1 unfortunately1
not only is it not obvious how to
apply it in the great majority of cases
in which its aid is needed1 but its
general validity is stoutly denied4 ,the
,hon4 and ,rev4 ,mr4 ,herbert1 a most
trustworthy authority1 not only asserts
as the result of his own observations
and experiments that many hybrids are
quite as fertile as the parent species1
but he goes so far as to assert that
the particular plant ,crinum capense is
much more fertile when crossed by a
distinct species than when fertilised by
its proper pollen6 ,on the other hand1
the famous ,gaertner1 though he took
the greatest pains to cross the
primrose and the cowslip1 succeeded only
once or twice in several years2 and
yet it is a well-established fact that
the primrose and the cowslip are only
varieties of the same kind of plant4
,again1 such cases as the following are
well established4 ,the female of
species ,a1 if crossed with the male of
species ,b1 is fertile2 but1 if the
female of ,b is crossed with the male of
,a1 she remains barren4 ,facts of this
kind destroy the value of the supposed
criterion4 ,if1 weary of the endless
difficulties involved in the
determination of species1 the
investigator1 contenting himself with
the rough practical distinction of
separable kinds1 endeavours to study
them as they occur in nature--to
ascertain their relations to the
conditions which surround them1 their
mutual harmonies and discordances of
structure1 the bond of union of their
parts and their past history1 he finds
himself1 according to the received
notions1 in a mighty maze1 and with1 at
most1 the dimmest adumbration of a
plan4 ,if he starts with any one clear
conviction1 it is that every part of a
living creature is cunningly adapted to
some special use in its life4 ,has not
his ,paley told him that that seemingly
useless organ1 the spleen1 is
beautifully adjusted as so much packing
between the other organs8 ,and yet1 at
the outset of his studies1 he finds
that no adaptive reason whatsoever can
be given for one-half of the
peculiarities of vegetable structure2 he
also discovers rudimentary teeth1
which are never used1 in the gums of the
young calf and in those of the foetal
whale2 insects which never bite have
rudimental jaws1 and others which never
fly have rudimental wings2 naturally
blind creatures have rudimental eyes2
and the halt have rudimentary limbs4
,so1 again1 no animal or plant puts on
its perfect form at once1 but all have
to start from the same point1 however
various the course which each has to
pursue4 ,not only men and horses1 and
cats and dogs1 lobsters and beetles1
periwinkles and mussels1 but even the
very sponges and animalcules commence
their existence under forms which are
essentially undistinguishable2 and this
is true of all the infinite variety of
plants4 ,nay1 more1 all living beings
march side by side along the high road
of development1 and separate the later
the more like they are2 like people
leaving church1 who all go down the
aisle1 but having reached the door some
turn into the parsonage1 others go down
the village1 and others part only in
the next parish4 ,a man in his
development runs for a little while
parallel with1 though never passing
through1 the form of the meanest worm1
then travels for a space beside the
fish1 then journeys along with the bird
and the reptile for his fellow
travellers2 and only at last1 after a
brief companionship with the highest of
the four-footed and four-handed world1
rises into the dignity of pure manhood4
,no competent thinker of the present
day dreams of explaining these
indubitable facts by the notion of the
existence of unknown and undiscoverable
adaptations to purpose4 ,and we would
remind those who1 ignorant of the facts1
must be moved by authority1 that no
one has asserted the incompetence of the
doctrine of final causes1 in its
application to physiology and anatomy1
more strongly than our own eminent
anatomist1 ,professor ,owen1 who1
speaking of such cases1 says 7,on the
,nature of ,limbs1 pp4 #ci1 #dj73 8,i
think it will be obvious that the
principle of final adaptations fails to
satisfy all the conditions of the
problem40 ,but1 if the doctrine of
final causes will not help us to
comprehend the anomalies of living
structure1 the principle of adaptation
must surely lead us to understand why
certain living beings are found in
certain regions of the world and not in
others4 ,the palm1 as we know1 will not
grow in our climate1 nor the oak in
,greenland4 ,the white bear cannot live
where the tiger thrives1 nor vice
versa1 and the more the natural habits
of animal and vegetable species are
examined1 the more do they seem1 on the
whole1 limited to particular provinces4
,but when we look into the facts
established by the study of the
geographical distribution of animals
and plants it seems utterly hopeless to
attempt to understand the strange and
apparently capricious relations which
they exhibit4 ,one would be inclined to
suppose a priori that every country
must be naturally peopled by those
animals that are fittest to live and
thrive in it4 ,and yet how1 on this
hypothesis1 are we to account for the
absence of cattle in the ,pampas of
,south ,america1 when those parts of
the ,new ,world were discovered8 ,it is
not that they were unfit for cattle1
for millions of cattle now run wild
there2 and the like holds good of
,australia and ,new ,zealand4 ,it is a
curious circumstance1 in fact1 that the
animals and plants of the ,northern
,hemisphere are not only as well adapted
to live in the ,southern ,hemisphere
as its own autochthones1 but are in many
cases absolutely better adapted1 and
so overrun and extirpate the aborigines4
,clearly1 therefore1 the species which
naturally inhabit a country are not
necessarily the best adapted to its
climate and other conditions4 ,the
inhabitants of islands are often
distinct from any other known species
of animal or plants 7witness our recent
examples from the work of ,sir ,emerson
,tennent1 on ,ceylon71 and yet they
have almost always a sort of general
family resemblance to the animals and
plants of the nearest mainland4 ,on the
other hand1 there is hardly a species
of fish1 shell1 or crab common to the
opposite sides of the narrow isthmus of
,panama4 ,wherever we look1 then1
living nature offers us riddles of
difficult solution1 if we suppose that
what we see is all that can be known of
it4 ,but our knowledge of life is not
confined to the existing world4
,whatever their minor differences1
geologists are agreed as to the vast
thickness of the accumulated strata
which compose the visible part of our
earth1 and the inconceivable immensity
of the time of whose lapse they are the
imperfect1 but the only accessible
witnesses4 ,now1 throughout the greater
part of this long series of stratified
rocks are scattered1 sometimes very
abundantly1 multitudes of organic
remains1 the fossilized exuviae of
animals and plants which lived and died
while the mud of which the rocks are
formed was yet soft ooze1 and could
receive and bury them4 ,it would be a
great error to suppose that these
organic remains were fragmentary relics4
,our museums exhibit fossil shells of
immeasurable antiquity1 as perfect as
the day they were formed1 whole
skeletons without a limb disturbed--nay1
the changed flesh1 the developing
embryos1 and even the very footsteps of
primeval organisms4 ,thus the
naturalist finds in the bowels of the
earth species as well defined as1 and
in some groups of animals more numerous
than1 those that breathe the upper air4
,but1 singularly enough1 the majority
of these entombed species are wholly
distinct from those that now live4 ,nor
is this unlikeness without its rule and
order4 ,as a broad fact1 the further
we go back in time the less the buried
species are like existing forms2 and
the further apart the sets of extinct
creatures are the less they are like
one another4 ,in other words1 there has
been a regular succession of living
beings1 each younger set being in a very
broad and general sense somewhat more
like those which now live4 ,it was
once supposed that this succession had
been the result of vast successive
catastrophes1 destructions1 and
re-creations en masse2 but catastrophes
are now almost eliminated from
geological1 or at least
palaeontological speculation2 and it is
admitted on all hands that the seeming
breaks in the chain of being are not
absolute1 but only relative to our
imperfect knowledge2 that species have
replaced species1 not in assemblages1
but one by one2 and that1 if it were
possible to have all the phenomena of
the past presented to us1 the
convenient epochs and formations of the
geologist1 though having a certain
distinctness1 would fade into one
another with limits as undefinable as
those of the distinct and yet separable
colours of the solar spectrum4 ,such
is a brief summary of the main truths
which have been established concerning
species4 ,are these truths ultimate and
irresolvable facts1 or are their
complexities and perplexities the mere
expressions of a higher law8 ,a
large number of persons practically
assume the former position to be
correct4 ,they believe that the writer
of the ,pentateuch was empowered and
commissioned to teach us scientific as
well as other truth1 that the account
we find there of the creation of living
things is simply and literally correct1
and that anything which seems to
contradict it is1 by the nature of the
case1 false4 ,all the phenomena which
have been detailed are1 on this view1
the immediate product of a creative fiat
and consequently are out of the domain
of science altogether4 ,whether this
view prove ultimately to be true or
false1 it is1 at any rate1 not at
present supported by what is commonly
regarded as logical proof1 even if it
be capable of discussion by reason2 and
hence we consider ourselves at liberty
to pass it by1 and to turn to those
views which profess to rest on a
scientific basis only1 and therefore
admit of being argued to their
consequences4 ,and we do this with the
less hesitation as it so happens that
those persons who are practically
conversant with the facts of the case
7plainly a considerable advantage7 have
always thought fit to range themselves
under the latter category4 ,the
majority of these competent persons have
up to the present time maintained two
positions1--the first1 that every
species is1 within certain defined or
definable limits1 fixed and incapable of
modification2 the second1 that every
species was originally produced by a
distinct creative act4 ,the second
position is obviously incapable of
proof or disproof1 the direct operations
of the ,creator not being subjects of
science2 and it must therefore be
regarded as a corollary from the first1
the truth or falsehood of which is a
matter of evidence4 ,most persons
imagine that the arguments in favour of
it are overwhelming2 but to some few
minds1 and these1 it must be confessed1
intellects of no small power and grasp
of knowledge1 they have not brought
conviction4 ,among these minds1 that of
the famous naturalist ,lamarck1 who
possessed a greater acquaintance with
the lower forms of life than any man of
his day1 ,cuvier not excepted1 and was
a good botanist to boot1 occupies a
prominent place4 ,two facts appear to
have strongly affected the course of
thought of this remarkable man--the
one1 that finer or stronger links of
affinity connect all living beings with
one another1 and that thus the highest
creature grades by multitudinous steps
into the lowest2 the other1 that an
organ may be developed in particular
directions by exerting itself in
particular ways1 and that modifications
once induced may be transmitted and
become hereditary4 ,putting these facts
together1 ,lamarck endeavoured to
account for the first by the operation
of the second4 ,place an animal in new
circumstances1 says he1 and its needs
will be altered2 the new needs will
create new desires1 and the attempt to
gratify such desires will result in an
appropriate modification of the organs
exerted4 ,make a man a blacksmith1 and
his brachial muscles will develop in
accordance with the demands made upon
them1 and in like manner1 says
,lamarck1 8the efforts of some
short-necked bird to catch fish without
wetting himself have1 with time and
perseverance1 given rise to all our
herons and long-necked waders40 ,the
,lamarckian hypothesis has long since
been justly condemned1 and it is the
established practice for every tyro to
raise his heel against the carcass of
the dead lion4 ,but it is rarely either
wise or instructive to treat even the
errors of a really great man with mere
ridicule1 and in the present case the
logical form of the doctrine stands on
a very different footing from its
substance4 ,if species have really
arisen by the operation of natural
conditions1 we ought to be able to find
those conditions now at work2 we ought
to be able to discover in nature some
power adequate to modify any given kind
of animal or plant in such a manner as
to give rise to another kind1 which
would be admitted by naturalists as a
distinct species4 ,lamarck imagined
that he had discovered this vera causa
in the admitted facts that some organs
may be modified by exercise2 and that
modifications1 once produced1 are
capable of hereditary transmission4 ,it
does not seem to have occurred to him
to inquire whether there is any reason
to believe that there are any limits to
the amount of modification producible1
or to ask how long an animal is likely
to endeavour to gratify an impossible
desire4 ,the bird1 in our example1
would surely have renounced fish dinners
long before it had produced the least
effect on leg or neck4 ,since
,lamarck's time1 almost all competent
naturalists have left speculations on
the origin of species to such dreamers
as the author of the 8,vestiges10 by
whose well-intentioned efforts the
,lamarckian theory received its final
condemnation in the minds of all sound
thinkers4 ,notwithstanding this
silence1 however1 the transmutation
theory1 as it has been called1 has been
a 8skeleton in the closet0 to many an
honest zoologist and botanist who had a
soul above the mere naming of dried
plants and skins4 ,surely1 has such an
one thought1 nature is a mighty and
consistent whole1 and the providential
order established in the world of life
must1 if we could only see it rightly1
be consistent with that dominant over
the multiform shapes of brute matter4
,but what is the history of astronomy1
of all the branches of physics1 of
chemistry1 of medicine1 but a narration
of the steps by which the human mind
has been compelled1 often sorely
against its will1 to recognize the
operation of secondary causes in events
where ignorance beheld an immediate
intervention of a higher power8 ,and
when we know that living things are
formed of the same elements as the
inorganic world1 that they act and
react upon it1 bound by a thousand ties
of natural piety1 is it probable1 nay
is it possible1 that they1 and they
alone1 should have no order in their
seeming disorder1 no unity in their
seeming multiplicity1 should suffer no
explanation by the discovery of some
central and sublime law of mutual
connexion8 ,questions of this kind
have assuredly often arisen1 but it
might have been long before they
received such expression as would have
commanded the respect and attention of
the scientific world1 had it not been
for the publication of the work which
prompted this article4 ,its author1
,mr4 ,darwin1 inheritor of a once
celebrated name1 won his spurs in
science when most of those now
distinguished were young men1 and has
for the last #bj years held a place in
the front ranks of ,british
philosophers4 ,after a circumnavigatory
voyage1 undertaken solely for the love
of his science1 ,mr4 ,darwin published a
series of researches which at once
arrested the attention of naturalists
and geologists2 his generalizations
have since received ample confirmation1
and now command universal assent1 nor
is it questionable that they have had
the most important influence on the
progress of science4 ,more recently ,mr4
,darwin1 with a versatility which is
among the rarest of gifts1 turned his
attention to a most difficult question
of zoology and minute anatomy2 and no
living naturalist and anatomist has
published a better monograph than that
which resulted from his labours4 ,such a
man1 at all events1 has not entered
the sanctuary with unwashed hands1 and
when he lays before us the results of
#bj years' investigation and reflection
we must listen even though we be
disposed to strike4 ,but1 in reading his
work it must be confessed that the
attention which might at first be
dutifully1 soon becomes willingly1
given1 so clear is the author's
thought1 so outspoken his conviction1 so
honest and fair the candid expression
of his doubts4 ,those who would judge
the book must read it2 we shall
endeavour only to make its line of
argument and its philosophical position
intelligible to the general reader in
our own way4 ,the ,baker-street
,bazaar has just been exhibiting its
familiar annual spectacle4
,straight-backed1 small-headed1
big-barrelled oxen1 as dissimilar from
any wild species as can well be
imagined1 contended for attention and
praise with sheep of half-a-dozen
different breeds and styes of bloated
preposterous pigs1 no more like a wild
boar or sow than a city alderman is
like an ourang-outang4 ,the cattle show
has been1 and perhaps may again be1
succeeded by a poultry show1 of whose
crowing and clucking prodigies it can
only be certainly predicated that they
will be very unlike the aboriginal
,phasianus gallus4 ,if the seeker after
animal anomalies is not satisfied1 a
turn or two in ,seven ,dials will
convince him that the breeds of pigeons
are quite as extraordinary and unlike
one another and their parent stock1
while the ,horticultural ,society will
provide him with any number of
corresponding vegetable aberrations
from nature's types4 ,he will learn with
no little surprise1 too1 in the course
of his travels1 that the proprietors
and producers of these animal and
vegetable anomalies regard them as
distinct species1 with a firm belief1
the strength of which is exactly
proportioned to their ignorance of
scientific biology1 and which is the
more remarkable as they are all proud of
their skill in originating such
8species40 ,on careful inquiry it is
found that all these1 and the many other
artificial breeds or races of animals
and plants1 have been produced by one
method4 ,the breeder--and a skilful one
must be a person of much sagacity and
natural or acquired perceptive
faculty--notes some slight difference1
arising he knows not how1 in some
individuals of his stock4 ,if he wish
to perpetuate the difference1 to form a
breed with the peculiarity in question
strongly marked1 he selects such male
and female individuals as exhibit the
desired character1 and breeds from
them4 ,their offspring are then
carefully examined1 and those which
exhibit the peculiarity the most
distinctly are selected for breeding1
and this operation is repeated until the
desired amount of divergence from the
primitive stock is reached4 ,it is then
found that by continuing the process of
selection--always breeding1 that is1
from well-marked forms1 and allowing no
impure crosses to interfere1--a race
may be formed1 the tendency of which to
reproduce itself is exceedingly strong2
nor is the limit to the amount of
divergence which may be thus produced
known1 but one thing is certain1 that1
if certain breeds of dogs1 or of
pigeons1 or of horses1 were known only
in a fossil state1 no naturalist would
hesitate in regarding them as distinct
species4 ,but1 in all these cases we
have human interference4 ,without the
breeder there would be no selection1 and
without the selection no race4 ,before
admitting the possibility of natural
species having originated in any
similar way1 it must be proved that
there is in nature some power which
takes the place of man1 and performs a
selection sua sponte4 ,it is the claim
of ,mr4 ,darwin that he professes to
have discovered the existence and the
modus operandi of this natural
selection1 as he terms it2 and1 if he be
right1 the process is perfectly simple
and comprehensible1 and irresistibly
deducible from very familiar but well
nigh forgotten facts4 ,who1 for
instance1 has duly reflected upon all
the consequences of the marvellous
struggle for existence which is daily
and hourly going on among living
beings8 ,not only does every animal live
at the expense of some other animal or
plant1 but the very plants are at war4
,the ground is full of seeds that
cannot rise into seedlings2 the
seedlings rob one another of air1 light
and water1 the strongest robber winning
the day1 and extinguishing his
competitors4 ,year after year1 the wild
animals with which man never interferes
are1 on the average1 neither more nor
less numerous than they were2 and yet we
know that the annual produce of every
pair is from one to perhaps a million
young1--so that it is mathematically
certain that1 on the average1 as many
are killed by natural causes as are
born every year1 and those only escape
which happen to be a little better
fitted to resist destruction than those
which die4 ,the individuals of a species
are like the crew of a foundered ship1
and none but good swimmers have a
chance of reaching the land4 ,such
being unquestionably the necessary
conditions under which living creatures
exist1 ,mr4 ,darwin discovers in them
the instrument of natural selection4
,suppose that in the midst of this
incessant competition some individuals
of a species 7,a7 present accidental
variations which happen to fit them a
little better than their fellows for the
struggle in which they are engaged1
then the chances are in favour1 not only
of these individuals being better
nourished than the others1 but of their
predominating over their fellows in
other ways1 and of having a better
chance of leaving offspring1 which will
of course tend to reproduce the
peculiarities of their parents4 ,their
offspring will1 by a parity of
reasoning1 tend to predominate over
their contemporaries1 and there being
7suppose7 no room for more than one
species such as ,a1 the weaker variety
will eventually be destroyed by the new
destructive influence which is thrown
into the scale1 and the stronger will
take its place4 ,surrounding conditions
remaining unchanged1 the new variety
7which we may call ,b7--supposed1 for
argument's sake1 to be the best adapted
for these conditions which can be got
out of the original stock--will remain
unchanged1 all accidental deviations
from the type becoming at once
extinguished1 as less fit for their post
than ,b itself4 ,the tendency of ,b to
persist will grow with its persistence
through successive generations1 and it
will acquire all the characters of a new
species4 ,but1 on the other hand1 if
the conditions of life change in any
degree1 however slight1 ,b may no
longer be that form which is best
adapted to withstand their destructive1
and profit by their sustaining1
influence2 in which case if it should
give rise to a more competent variety
7,c71 this will take its place and
become a new species2 and thus1 by
natural selection1 the species ,b and ,c
will be successively derived from ,a4
,that this most ingenious hypothesis
enables us to give a reason for many
apparent anomalies in the distribution
of living beings in time and space1 and
that it is not contradicted by the main
phenomena of life and organization
appear to us to be unquestionable2 and
so far it must be admitted to have an
immense advantage over any of its
predecessors4 ,but it is quite another
matter to affirm absolutely either the
truth or falsehood of ,mr4 ,darwin's
views at the present stage of the
inquiry4 ,goethe has an excellent
aphorism defining that state of mind
which he calls ,thtige ,skepsis--active
doubt4 ,it is doubt which so loves
truth that it neither dares rest in
doubting1 nor extinguish itself by
unjustified belief2 and we commend this
state of mind to students of species1
with respect to ,mr4 ,darwin's or any
other hypothesis1 as to their origin4
,the combined investigations of another
#bj years may1 perhaps1 enable
naturalists to say whether the modifying
causes and the selective power1 which
,mr4 ,darwin has satisfactorily shown
to exist in nature1 are competent to
produce all the effects he ascribes to
them1 or whether1 on the other hand1 he
has been led to over-estimate the value
of his principle of natural selection1
as greatly as ,lamarck overestimated
his vera causa of modification by
exercise4 ,but there is1 at all
events1 one advantage possessed by the
more recent writer over his
predecessor4 ,mr4 ,darwin abhors mere
speculation as nature abhors a vacuum4
,he is as greedy of cases and precedents
as any constitutional lawyer1 and all
the principles he lays down are capable
of being brought to the test of
observation and experiment4 ,the path he
bids us follow professes to be1 not a
mere airy track1 fabricated of ideal
cobwebs1 but a solid and broad bridge of
facts4 ,if it be so1 it will carry us
safely over many a chasm in our
knowledge1 and lead us to a region free
from the snares of those fascinating
but barren ,virgins1 the ,final
,causes1 against whom a high authority
has so justly warned us4 8,my sons1 dig
in the vineyard10 were the last words
of the old man in the fable2 and1
though the sons found no treasure1 they
made their fortunes by the grapes4
