"Fechner laid down the general outlines of his program in ZendAvesta, the book about heaven and the future life. Imagine sending a graduate student of psychology nowadays to the Divinity School for a course in immortality as preparation for advanced experimental work in psychophysics! How narrow we have become!"

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

“The historical approach to understanding of scientific fact is what differentiates the scholar in science from the mere experimenter.”

“always seemed to me the nearest approach to genius of anyone with whom I have been closely associated.… He was competent with languages, and could ad lib in Latin when the occasion required it.

“Scientific truth, like puristic truth, must come about by controversy. Personally this view is abhorrent to me. It seems to mean that scientific truth must transcend the individual, that the best hope of science lies in its greatest minds being often brilliantly and determinedly wrong, but in opposition, with some third, eclectically minded, middle-of-the-road nonentity seizing the prize while the great fight for it, running off with it, and sticking it into a textbook for sophomores written from no point of view and in defense of nothing whatsoever. I hate this view, for it is not dramatic and it is not fair; and yet I believe that it is the verdict of the history of science.”
