The Speech of Monkeys

Whatever may be the intrinsic difference between reason and instinct, it is evident to my mind that the same motives actuate both man and ape in the same way, but not to the same extent. I am aware that many acts performed by Simians are meaningless to them and done without a well-defined motive. The strong physical resemblance between man and ape often causes one to attach more importance to the act than it really justifies. In many cases the same act performed by some other animal less like man would scarcely be noticed. To teach an ape or monkey to eat with knife, fork, cup and spoon, to use a napkin and chair, or such like feats, does not indicate to my mind a high order of reason; nor it is safe to judge the mental status of these creatures from such data. When he is placed under new conditions and committed to his own resources, we are then better able to judge by his conduct whether he is actuated by reason or not. [Sidenote: CONNECTING CAUSES AND EFFECTS] In any simple act where a monkey can see the cause connected with, and closely followed by, the effect, he is actuated by reason, and while he may not be able to explain to his own mind a remote or complex cause but simply accepts the fact, it does not make the act any less rational in a monkey than the same act would be in man where he fails to grasp the ultimate cause. The difference is that man is able to trace the connecting causes and effects through a longer series than a monkey can. Man assigns a more definite reason for his acts than a monkey can; but it is also true that one man may assign a more definite reason for his acts than another man can for his when prompted by the same motives to the same act.
