This book contains the substance of a course of lectures recently given by the writer in the Queen Street Hall, Edinburgh. Its purpose is to indicate the Natural Principles governing the relation between Mental Action and Material Conditions, and thus to afford the student an intelligible starting-point for the practical study of the subject. In commencing a course of lectures on Mental Science, it is somewhat difficult for the lecturer to fix upon the best method of opening the subject. It can be approached from many sides, each with some peculiar advantage of its own; but, after careful deliberation, it appears to me that, for the purpose of the present course, no better starting-point could be selected than the relation between Spirit and Matter.
