times it will jump up a
hundred and one times; so that if you desire its company at dinner you
can have it only on its own terms. If Weismann really thought that
cats act thus without any consciousness or any purpose, immediate or
ulterior, he must have known very little about cats. But a thoroughgoing
Weismannite, if any such still survive from those mad days, would
contend that I am not at present necessarily conscious of what I am
doing; that my writing of these lines, and your reading of them, are
effects of Circumstantial Selection; that I heed know no more about
Darwinism than a butterfly knows of a lizard's appetite; and that the
proof that I actually am doing it unconsciously is that as I have spent
forty years in writing in this fashion without, as far as I can see,
producing any visible effect on public opinion, I must be incapable of
learning from experience, and am therefore a mere automaton. And
the Weismannite demonstration of this would of course be an equally
unconscious effect of Circumstantial Selection.

DARWINISM NOT FINALLY REFUTABLE

Do not too hastily say that this is inconceivable. To Circumstantial
Selection all mechanical and chemical reactions are possible, provided
you accept the geologists' estimates of the great age of the earth, and
therefore allow time enough for the circumstances to operate. It is true
that mere survival of the fittest in the struggle for existence plus
sexual selection fail as hopelessly to account for Darwin's own life
work as for my conquest of the bicycle; but who can prove that there
are not other soulless factors, unnoticed or undiscovered, which only
require imagination enough to fit them to the evolution of an automatic
Jesus or Shakespear? When a man tells you that you are a product of
Circumstantial Selection solely, you cannot finally disprove it. You can
only tell him out of the depths of your inner conviction that he is a
fool and a liar. But as this, though British, is uncivil, it is wiser to
offer him the counter-assurance that you are the product of Lamarckian
evolution, formerly called Functional Adaptation and now Creative
Evolution, and challenge him to disprove _that_, which he can no more
do than you can disprove Circumstantial Selection, both forces being
conceivably able to produce anything if you only give them rope enough.
You may also defy him to act for a single hour on the assumption that he
may safely cross Oxford Street in a state of unco
