may be deceived by these instincts when it leaves its primitive environment. We see an example of this in the moth which burns itself in the flame. The instinct was sound in the days when the sun was the only luminary, but no evolution has taken place to adapt this instinct to the existence of lamps. We may admit that every instinct had its use at the time when it first came into existence. This may be true of the fighting instinct, but it does not follow that the combative instinct is useful to man to-day. Instinct is extremely conservative, and survives the circumstances that produced it. For instance, the wolf, wishing to cover up its tracks, buries its excrement; the dog, a town dweller, stupidly scrapes the pavement. In the latter case instinct has become senseless, purposeless.
Man has retained many rudimentary and functionless instincts. He is able to modify them, but in his case the task is peculiarly complex. Man is distinguished from other animals by his incomparably greater power of modifying the natural environment to suit his own purposes. But this being so, man should transform his instincts to adapt them to the changed circumstances. Now these instincts are tenacious, and the struggle is hard. All the more, therefore, is it necessary. Whole species of lower animals became extinct because they were unable to modify their instincts as the environment changed. “Is man also to die out from want of the will to change his instincts? He can change them, or he could if he would. Man alone has the power of choice, and consequently can err. But this curse of the liability to error is the necessary consequence of freedom, and it gives birth to the blessed power man possesses to learn and to transform himself.” Yet man makes very little use of this power. He is still encumbered with archaic instincts. He accepts them complacently. He has an excessive esteem for what is old precisely because he is swayed by hereditary instincts which he has unconsciously come to revere.
In the kingdom of the one-eyed, we ought not to make the blind man king. Because we all have combative instincts, it does not follow that we should give these
