First published in 1927, An Anthology of Mysticism and Mystical Philosophy is a valuable contribution to the literature of mysticism in general, both in its theoretical and experimental aspects. It contains over seven hundred and fifty quotations from one hundred and fifty-eight ancient and modern mystical, philosophical, and scientific works. This book also acts as a supplement to William Kingsland's previous volume Rational Mysticism for it is illustrative of the principles therein set forth.
