We are now passing through a period of popular reaction against the scientific materialism of the last century. The common people are awaking to the fact that the mental state has much to do With bodily health and disease. The book makers, in their efforts to satisfy the universal demand for teaching on various phases of mental healing, have ﬂooded us with literature, much of which is premature, unscientific, incomplete, and highly disastrous in its misleading inﬂuence upon the popular mind and morals. It is to be deplored that practically every system of modern mental healing has declared as the secret of its success its association with some creed or cult — claiming that physical healing was dependent upon the acceptance of some particular moral teaching or system of religious belief. At the very outset we desire to separate the study of mental healing from any and all particular brands of religion — not-from religion as a state of mind, but from any particular system, sect, or form of religious belief.
