through natural selection, or are the indirect result of other instincts and faculties, such as sympathy, reason, experience, and a tendency to imitation; or again, whether they are simply the result of long-continued habit." Darwin distinguishes between "the all-important emotion of sympathy," and that of love. "A mother may passionately love her sleeping and passive infant, but she can hardly at such times be said to feel sympathy for it"; but he includes both love and sympathy under the head of "sympathetic emotions"; and on page 163 he says: "With mankind, selfishness, experience, and imitation probably add, as Mr. Bain has shown, to the power of sympathy; for we are led by the hope of receiving good in return to perform acts of sympathetic kindness to others; and sympathy is much strengthened by habit." Again, on page 166, "instinctive love and sympathy" would seem to be contrasted with love and sympathy as habit, the increase of such feelings in the race through habit, elsewhere more or less distinctly asserted, being here ignored: "Although man, as he now exists, has few special instincts, having lost any which his early progenitors may have possessed, this is no reason why he should not have retained, from an extremely remote period, some degree of instinctive love and sympathy for his fellows. We are, indeed, all conscious that we do possess such sympathetic feelings; but our consciousness does not tell us whether they are instinctive, having originated long ago in the same manner as with the lower animals, or whether they have been acquired by each of us during our early years." But again, on page 220, sympathy is referred to as an element of the social instincts:[13] "It should, however, be borne in mind that the enforcement of public opinion depends on our appreciation of the approbation and disapprobation of others; and this appreciation is founded on our sympathy, which it can hardly be doubted was originally developed through natural selection as one of the most important elements of the social instincts"; though, on pages 167, 168, the social instinct is again contrasted with sympathy, since according to Darwin the desire for the approbation of others and the consequent yielding to their wishes is the result of sympathy: "Thus the social instincts, which must have been acquired by man in a very rude state, and probably even by his early ape-like progenitors, still give the impulse to some of his best actions; but his actions are in a higher degree determined by the expressed wishes and judgments of his fellow-men." Again the social and the maternal instincts and sympathy are identified and classed as under the dominion of the moral sense, pages 168-170: "It is evident, in the first place, that with mankind the instinctive impulses have different degrees of strength; a savage, will risk his own life to save that of a member of the same community, but will be wholly
