“Behavior is a difficult subject matter, not because it is inaccessible, but because it is extremely complex. Since it is a process, rather than a thing, it cannot easily be held still for observation. It is changing, fluid, evanescent, and for this reason it makes great technical demands upon the ingenuity and energy of the scientist.”
