Cumulative Record. Chapter 24: The Flight from the Laboratory. Quote 15

Experimental psychology has suffered perhaps its greatest loss of manpower because competent investigators, beginning with a descriptive interest in behavior, have passed almost immediately to an explanatory preoccupation with what is going on inside the organism. In discussing this flight to the inner man I should like to believe that I am whipping a dead horse, but the fact remains that human behavior is still most commonly discussed in terms of psychic or physiological processes.
