From the other side, it is not difficult to find evidence that continued inquiry and reflection have led to the abatement, if not the actual withdrawal, of scientific hypotheses which seemed at variance with common belief, and which might be taken as adverse to religious thought. For example, as a branch of the inquiry connected with the theory of development of species, and coming directly upon the position of man in the scale of being, we had for a time a wonderful amount of observation, description, and discussion concerning monkeys and apes. Laborious inquiries became provocative of grotesque fancy. In the train of science came the workers who minister to the popular imagination, and there appeared a whole series of comic pictures, amusing narratives, and even musical compositions, representing monkeys and apes as taking part in human occupations. These have left their testimony to the power of scientific hypothesis in determining the thought and interest of the time during which they find favor. It was demonstrated incontestably that the anatomical structure of the ape was much more like to that of man than the structure of the dog, or the horse; and that the brain of the ape was so like in form and arrangement to the human brain, that it might be represented as a smaller and undeveloped example of the human brain. But when the work of observation and description had been well nigh completed; when the work of deliberate thinking was commenced with the assurance that the facts were pretty fully and fairly before us, there came a considerable abatement for the enthusiasm of scientific speculation in the new line of discovery. Next came the acknowledgment that even with all the analogies and homologies of structure, seen and unseen, there was a vast chasm between the ape and man. Forthwith, the stimulus to comic talent began to die away; and it must be confessed that the department of anthropology has not been greatly advanced from this new region of observation.
