Abstract
This, the fifth volume to appear in the "authoritative" edition of The Works of William James, is the first that is not strictly based on a previously published work, although 11 of the 21 essays were included in Collected Essays and Reviews, edited in 1920 by Ralph Barton Perry, and 2 in Memories and Studies, edited in 1911 by Henry James, the philosopher’s son. The selection is based on subject matter, "philosophy in a narrower sense" than was customary for James, and subsequent volumes will include parallel collections of "essays in psychology, in religion and morality, and in psychic research".
