If these statements startle, it is because matter has been defined and maligned by philosophers and theologians, who were ignorant alike of its mystical and transcendental powers. (Ib., p. 51.) Two courses, and two only, are possible: either let us open our doors freely to the conception of creative acts, or, abandoning them let us radically change our notions of matter. (Ib., p. 191.) Without this total revolution of the notions now prevalent, the evolution hypothesis must stand condemned. (Ib., p. 133.) If we look at matter as defined by our scientific text-books, the notion of conscious life coming out of it cannot be formed by the mind. (Ib., p. 191.) Spirit and matter have ever been present to us in the rudest contrast: the one as all noble, the other as all vile. But is this correct? Upon the answer to this question, all depends. (Ib., p. 133.) #/ Physiology proves Materialism to be true, and the following testimony to that fact by eminent scientific men is only a small part of what might be quoted of similar tenor: Bain tells us: The most careful and studied observations of physiologists have shown beyond question, that the brain as a whole is indispensible to thought, feeling, and volition. Dr. Ferrier says: The brain is the organ of mind, and that mental operations are possible only in and through it. This fact is so well established that we may start from it as we should from any ultimate fact. Prof. Virchow, of Berlin, says: Every one must admit that without a brain, nay, more, without a good and well developed brain, the human mind has no existence.--Man has a mind and rational will only in as much and in so far as he possesses a brain. Huxley says: What we call the operations of the mind are functions of the brain, and the materials of consciousness are products of cerebral activity. Sensations are products of the inherent properties of the thinking organ. Tyndall says: We believe that every thought and every feeling has its definite mechanical correlative in the nervous system; that it is accompanied by a certain separation and remarshalling of the atoms of the brain. Dr. Maudsley says: I do not go beyond what facts warrant, when I say that, when a thought occurs in the mind, there necessarily occurs a correlative change in the gray matter of the brain. Without it, the thought could not arise; with it, it can not fail to rise.
