These lectures, delivered at New York University from February 20th till March 1, 1913, appeal less to students and philosophers than to the cultured public at large. I take this opportunity of expressing my sincere gratitude to the New York University, and especially to Chancellor Elmer E. Brown, for all the kindness and interest shown to me during my stay in New York.
