In writing of the social instinct, Darwin begins with it as already existent, and seems, moreover, to maintain concerning it a theory of purpose elsewhere denied in his works and, indeed, antagonistic to the whole principle of the struggle for existence. He says: "It has often been assumed that animals were in the first place rendered social, and that they feel, as a consequence, uncomfortable when separated from each other, and comfortable whilst together; but it is a more probable view that these sensations were first developed, _in order that_ those animals which would profit by living in society, _should be induced to live together_, in the same manner as the sense of hunger and the pleasure of eating were, no doubt, first acquired, in order to induce animals to eat."[12] If it were not for the expressions "should be induced" and "to induce," the words "in order that," taken in connection with what follows, might be interpreted as referring to mere sequence of time, as, on page 199, where Darwin refers to the "social faculties" simply as antecedent to society, they evidently do. For he says: "In order that primeval man, or the ape-like progenitors of man, should become social, they must have acquired the same instinctive feelings which induce other animals to live in a body." The sentences referred to which follow the first quotation are as follows: "The feeling of pleasure from society is probably an extension of the parental or filial affections, since the social instinct seems to be developed by the young remaining for a long time with their parents; and this extension may be attributed in part to habit, but chiefly to natural selection. With those animals which were benefited by living in close association, the individuals which took the greatest pleasure in society would best escape various dangers, whilst those that cared least for their comrades, and lived solitary, would perish in greater numbers. With respect to the origin of the parental and filial affections, which apparently lie at the base of the social instincts, we know not the steps by which they have been gained; but we may infer that it has been to a large extent through natural selection." The passage may possibly be consistently explained by the idea of the Survival of the Fittest, but it is at least very unclear in its wording. At the beginning of Chapter IV. of the same book, Darwin also gives a synopsis of the development of the moral sense from the social instincts, through the pleasure of association and service, remorse being a result of the power of representation, regard for the approbation and disapprobation of fellows arising from sympathy with them until resulting habit plays a very important part in guiding the conduct of the individual. Another passage, however, again introduces an antagonism between habit, instinct, and reason, and natural selection: "It is impossible to decide in many cases whether certain social instincts have been acquired
