The quotation from Francesco Lana (Chapter I) was brought to the attention of the readers of Science, August 25, 1939, by M. F. Ashley-Montagu. Permission to quote from George Bernard Shaw’s The Adventures of the Black Girl in Her Search for God (Chapter IV) was kindly granted by the Society of Authors. The story about Dean Briggs (Chapter XIV) was reported by Mary E. Woolley in the American Scholar, Volume 1, Number 1, 1932. The quotation from Carl R. Rogers (Chapter XXIX) is to be found on page 212 of the Harvard Educational Review, Fall, 1948, and is used with permission. I am indebted to J. G. Beebe-Center for a helpful reading of the manuscript. I am also grateful for editorial assistance from Mrs. Diana S. Larsen and Miss Dorothy Cohen.
