William James, The Philosophical Review (1892)
“ I have never claimed, for instance, as Professor Ladd seems to think I claim, that psychology as it stands to-day, is a natural science, or in an exact way a science at all. Psychology, indeed, is to-day hardly more than what physics was before Galileo, what chemistry was before Lavoisier. It is a mass of phenomenal description, gossip, and myth, including, however, real material enough to justify one in the hope that with judgment and good-will on the part of those interested, its study may be so organized even now as to become worthy of the name of natural science at no very distant day. ”
