10 Studies in Animal Behavior 



comparative psychologists these questions, except 

 perhaps the last, are no longer in the foreground of

 in philosophy we do not solve our problems; we

Modern psychology troubles itself very little

 ness which still occupy us. Where did consciousness 

 begin in the course of evolution, if it can be said to
