These views of existence naturally colour all views of life and of the existence of the Soul. And here steps in the profound difference between Atheism and Pantheism; both posit an Existence at present inscrutable by human faculties, of which all phenomena are modes; but to the Atheist that Existence manifests as Force-Matter, unconscious, unintelligent, while to the Pantheist it manifests as Life-Matter, conscious, intelligent. To the one, life and consciousness are attributes, properties, dependent upon arrangements of matter; to the other they are fundamental, essential, and only limited in their manifestation by arrangements of matter. Despite the attraction held for me in Spinoza’s luminous arguments, the over-mastering sway which Science was beginning to exercise over me drove me to seek for the explanation of all problems of life and mind at the hands of the biologist and the chemist. They had done so much, explained so much, could they not explain all? Surely, I thought, the one safe ground is that of experiment, and the remembered agony of doubt made me very slow to believe where I could not prove. So I was fain to regard life as an attribute, and this again strengthened the Atheistic position. “Scientifically regarded, life is not an entity but a property; it is not a mode of existence, but a characteristic of certain modes. Life is the result of an arrangement of matter, and when rearrangement occurs the former result can no longer be present; we call the result of the changed arrangement death. Life and death are two convenient words for expressing the general outcome of two arrangements of matter, one of which is always found to precede the other."[9] And then, having resorted to chemistry for one illustration, I took another from one of those striking and easily grasped analogies, facility for seeing and presenting which has ever been one of the secrets of my success
