So far as consciousness goes, one does one's thinking before one knows what he is to think about. - Edwin Boring

It is not likely that the history of psychology can be written in the next three centuries without mention of Freud's name and still claim to be a general history of psychology... Perhaps, had Freud been smothered in his cradle, the times would have produced a substitute, It is hard to say. The dynamics of history lack control experiments.

The experimental psychologist... needs historical sophistication within his own sphere of expertness. Without such knowledge he sees the present in distorted perspective, he mistakes old facts and old views for new, and he remains unable to evaluate the significance of new movements and methods. In this matter I can hardly state my faith too strongly. A psychological sophistication that contains no component of historical orientation seems to me to be no sophistication at all.

American psychology inherited its physical body from German experimentalism, but it got its mind from Darwin.
