While admitting that physiological considerations reveal a much wider interval between man and the anthropoid apes than anatomical data require, M. Broca would hardly allow that the former exhibits anything peculiar in his mental action. So, also, Mr. Darwin says that man and the higher mammals “have some few instincts in common. All have the same senses, intuitions, and sensations—similar passions, affections, and emotions, even the more complex ones; they feel wonder and curiosity; they possess the same faculties of imitation, attention, memory, imagination, and reason, though in very different degrees.”[368] The faculty of articulate speech, moreover, is said not in itself to offer “any insuperable objection to the belief that man has been developed from some lower form;” while the taste for the “beautiful” is shown not to be peculiar to the human mind.[369] The moral sense is supposed by Mr. Darwin to be the most distinctive characteristic of man; but even this is asserted to have been developed out of the social instincts which man and many of the lower animals have in common.[370] Finally, self-consciousness, abstraction, &c., even if peculiar to man, are declared to be “the incidental results of other highly-advanced intellectual faculties;”[371] and these again are mainly due to the continued use of a highly-developed language, which originated in “the imitation and modification, aided by signs and gestures, of various natural sounds, the voices of other animals and man’s own instinctive cries.”[372]
