Dr. Skinner is at present Assistant Professor of Psychology at the University of Minnesota. He began the series of essays in 1931 as part of his Ph.D. thesis at Harvard. It is largely a semi-Watsonian enterprise and begins historically with the newer conceptions instigated by the Darwinian conceptions from which he passes rapidly to the generic conceptions of stimulus and response. Then to the typical experimental box which has told us a lot of superficial facts about the behavior of lower animals. These are recorded—sS^p tray, R: approach—S: food, and R, seizing kind of recording.

It is all very academic and has no relation to the deeper instinctual life either of the lower animals or man. One might wish that the academic psychologist would wake up and turn over and find that man is not a rat or a cat and that the so-called experimental behavioristic mode of approach is dated—at least 40 years.
