If we return to the conflict of groups we shall see that even there purposive selection enters. How (we may ask) do those qualities of obedience, willingness to help another, and the like, arise in a community and thus enable it to win the victory over a less organised or more savage enemy? Surely it is not a sufficient answer to say that these qualities have been somehow developed, and then have contributed to the victory of the community possessing them. All through civilised life, and probably throughout a great part of savage life, there is the keenest enquiry into and perception of the qualities which will make for success. These qualities are carefully selected and positively fostered. You drill your armies--that is, you cultivate the habit of discipline and all that discipline implies--so that the victory may be gained; in other words, the quality is not produced by natural selection at all. The issue may resemble the result of natural selection, for it leads to conflict and defeat of the unfit; but the conqueror is he who has foreseen the conditions of the struggle: has deliberately equipped his forces for the fight, and been the intelligent organiser of victory. Even in the case of competition between individuals, at least among civilised men, it is clear that natural selection is very far from being the only factor. A man trains himself for a profession. It does not just somehow come about that a number of people accidentally develop certain varieties of occupation, and that natural selection makes play with this result, cutting off the unfit and leaving only those who are fairly well adapted to their positions. Something of this sort no doubt takes place to a limited extent; but, so far as it does take place, our methods are denounced as defective and, perhaps, as old-fashioned. 'Haphazard' is a wasteful principle, and should be superseded by intelligent initiative and deliberate preparation. And this indeed is the usual process. One adapts oneself carefully and of set purpose to the conditions of one's life, instead of simply waiting for natural selection to cut one off should one happen to be unfit. Even among animals there are certain processes which cannot be brought under natural selection. There are the first efforts, slight as they may be, towards learning by experience. There are also all those facts which Darwin classes under sexual selection, where there is a positive choosing, due no doubt not to intelligent purpose but nevertheless to a subjective impulse. This marks the beginning of the end of the reign of natural selection, because in it for the purely objective or external factor there is substituted an internal, subjective factor; instead of the process of cutting off unsuitable individuals among chance varieties there appears the process of selecting that variety which pleases or attracts.
