The
Position of Science
by John Tyndall
The doctrine of evolution derives man, in his
totality, from the interaction of organism and
environment through countless ages past. The human
understanding, for example -- that faculty which
Mr. Spencer has turned so skillfully round upon its
own antecedents -- is itself a result of the play
between organism and environment through cosmic
ranges of time. Never, surely, did prescription
plead so irresistible a claim. But then it comes to
pass that, over and above his understanding, there
are many other things appertaining to man whose
prescriptive rights are quite as strong as those of
the understanding itself. It is a result, for
example, of the play of organism and environment
that sugar is sweet, and that aloes are bitter;
that the smell of henbane differs from the perfume
of a rose. Such facts of consciousness (for which,
by the way, no adequate reason has ever been
rendered) are quite as old as the understanding;
and many other things can boast an equally ancient
origin. Mr. Spencer at one place refers to that
most powerful of passions -- the amatory passion --
as one which, when it first occurs, is antecedent
to all relative experience whatever; and we may
press its claim as being at least as ancient, and
as valid, as that of the understanding itself. Then
there are such things woven into the texture of man
as the feelings of awe, reverence, wonder -- and
not alone the sexual love just referred to, but the
love of the beautiful, physical, and moral, in
nature, poetry, and art. There is also that
deep-set feeling, which, since the earliest dawn of
history, and probably for ages prior to all
history, incorporated itself in the religions of
the world. You, who have escaped from these
religions into the high-and-dry light of the
intellect, may deride them; but in so doing you
deride accidents of form merely, and fail to touch
the immovable basis of the religious sentiment in
the nature of man. To yield this sentiment
reasonable satisfaction is the problem of problems
at the present hour. And grotesque in relation to
scientific culture as many of the religions of the
world have been and are -- dangerous, nay,
destructive, to the dearest privileges of freemen
as some of them undoubtedly have been, and would,
if they could, be again -- it will be wise to
recognize them as the forms of a force, mischievous
if permitted to intrude on the region of objective
knowledge, over which it holds no command,
but capable of adding in the region of
poetry and emotion, inward
completeness and dignity to man.
Feeling, I say again, dates from as old an
origin and as high a source as intelligence, and it
equally demands its range of play. The wise teacher
of humanity will recognize the necessity of meeting
this demand, rather than of resisting it on account
of errors and absurdities of form. What we should
resist, at all hazards, is the attempt made in the
past, and now repeated, to found upon this
elemental bias of man's nature a system which
should exercise despotic sway over his intellect. I
have no fear of such a consummation. Science has
already to some extent leavened the world; it will
leaven it more and more. I should look upon the
mild light of science breaking in upon the minds of
the youth of Ireland, and strengthening gradually
to the perfect day, as a surer check to any
intellectual or spiritual tyranny which may
threaten this island than the laws of princes or
the swords of emperors. We fought and won our
battle even in the Middle Ages: should we doubt the
issue of another conflict with our broken foe?
The impregnable position of science may be
described in a few words. We claim, and we shall
wrest from theology, the entire domain of
cosmological theory. All schemes and systems which
thus infringe upon the domain of science must, in
so far as they do this, submit to its control, and
relinquish all thought of controlling it. Acting
otherwise proved always disastrous in the past, and
it is simply fatuous today. Every system which
would escape the fate of an organism too rigid to
adjust itself to its environment must be plastic to
the extent that the growth of knowledge demands.
When this truth has been thoroughly taken in,
rigidity will be relaxed, exclusiveness diminished,
things now deemed essential will be dropped, and
elements now rejected will be assimilated. The
lifting of the life is the essential point, and as
long as dogmatism, fanaticism, and intolerance are
kept out, various modes of leverage may be employed
to raise life to a higher level.
