Now it appears to us that, in quite an analogous way, Darwin overlooks or contests the fact that with _free moral self-determination_ something specifically new comes into existence. He certainly discusses the origin of the moral qualities of man more in detail than he does the origin of his intellectual qualities. He derives them, in their first beginnings, from the fixity, transmission and increase of the _social_ impulses and instincts. These, being the basis of the whole moral development, and leading in their more mature form to love and to sympathy, originated by natural selection; and the other moral qualities, such as moral sense and conscience, progressed more by the effect of custom, by the power of reflection, instruction, and religion, than by natural selection. Higher and lower, common and special, permanent and transitory instincts come into collision {121} with one another. The dissatisfaction of man when any of the lower, special, and transitory instincts have overcome the higher, common and permanent, and the resolution to act differently for the future, is _conscience_. Darwin considers that one a _moral being_ who is capable of comparing with one another his past and future actions and motives, of approving some of them and of disapproving others; and the fact that man is the only creature who can with certainty be ranked as a moral being is, according to Darwin, the greatest of all differences between man and animals. Here, again, the whole central point of the investigation as to the origin of man does not lie in the question of the origin of the instincts between which the moral subject, acting in moral self-determination, has to choose. For it is clear that the beginnings of these instincts are also present in the animal world. But the main question is, how did this faculty and necessity of choosing, this conscience and responsibility, this "moral sense," as Darwin calls it, originate? Now to this question we have a plain answer in the before-mentioned utterances of Darwin: It originated not as a _product_ of the social instincts--it only has these instincts for its preceding condition, object and instrument; but it originated as a product of other agencies, which act upon these impulses and instincts, operate with them, choose between them; and as these other agencies Darwin mentions the high development of the intellectual powers. That this is his opinion, we can clearly see from an expression with which he introduces his essay on the origin of "moral sense": "The following proposition seems to me in a high degree probable--namely, that {122} any animal whatever, endowed with well-marked social instincts, would inevitably acquire a moral sense or conscience, _as soon as its intellectual powers had become as well, or nearly as well developed, as in man_." These intellectual powers which moral feeling and conscience require at their birth, are certainly,
