"Aping is the hardest trick which an honest ape can do," declared Professor Wolfgang Kohler last night before the Philosophical Club. Professor Kohler, who is Exchange Lecturer from Germany to Clark University, spoke on his experiences with apes and the hearing of his experiments on psychology.

The principal fact upon which Professor Kohler dwelt was the new view of psychology which his research has given him. "In the field of animal psychology," he declared, "altogether too much emphasis is laid on the subjective side of the work. The experimenter too often tries to prove the inferiority of brute intelligence. What science wants is an objective estimate of the standards of animal intelligence."

Another fact which Professor Kohler stressed was the mistaken idea of ape psychology which is held by many persons. "Apes do not ape," was the epitome of his discourse. Simian intelligence is not imitative; its advances are through trial and error or by a sudden comprehension of the key facts of a situation.
