The seven lectures presented here were delivered in New York for the purpose of presenting the testimony of science as to the relation of matter and of consciousness; to enable the hearers to observe the identical manifestation of these relations and of certain basic laws in successively higher states of being, and thus to bring to them a realization of the universality of the evolutionary process and its actuality; and to deal somewhat with the nature of the expanded states of consciousness and the enlarged life toward which all mankind is traveling.
Anyone who had read "e;The Greatest Thing in the World"e; could not help but desire to see and hear its author; and, when Professor Drummond visited Boston in the spring of 1893, the capacity of lecture halls was taxed to the utmost.
