itation of the ethical significance of the principle of natural
selection. For, when we come to this crucial question of conduct,
it is not allowed to give any criterion of moral validity. More
comprehensive attempts on the same lines as Darwin's have been made
subsequently; and various writers have tried to show how the moral
criterion may be resolved into social efficiency, or how it may be
derived from a problematic future state of the human race on this
earth when the need for struggle has disappeared and all things
go smoothly. The former view may be found in Sir Leslie Stephen's
'Science of Ethics'; the latter is the peculiar property of Mr Herbert
Spencer. Somewhat unwillingly I must for the present leave these
special views without consideration,[2] because I wish to bring out
still more plainly the various attitudes of the evolutionists to
morality, and especially to draw attention to a view very different
from those just mentioned, though not altogether without support in
Darwin, which, as put forward some years ago by the late Professor
Huxley[3], produced no little flutter in scientific dovecots.

refer to my' Ethics of Naturalism,' chap. viii. (chap. ix. in the new
edition). The same volume contains a more exhaustive examination than
is possible in this lecture of the whole subject of evolutionist
ethics.]

1894 this was republished, with prolegomena, in vol. ix. of 'Collected
Essays,' with the title, "Evolution and Ethics, and other Essays."]
Professor Huxley reviewed what he called the cosmic process as it was
guided by the law of evolution. He showed how at each step of that
process new results were only attained by enormous waste and pain on
the part of those living creatures which were thrust aside as unfit
for their surroundings, and he held consequently that the whole cosmic
process is of an entirely different character from what we must mean
when we use the term 'moral.' According to him morality is opposed
to the method of evolution, and cannot be based upon the theory of
evolution. It is of independent worth; but Professor Huxley, perhaps
wisely, refrained from investigating its justification, while
enforcing "the apparent paradox that ethical nature, while born of
cosmic nature, is necessarily at enmity with its paren
