(4) _Non-theistic Idealism_. Somewhat less unmotived, if we look upon it from a merely intellectual point of view, is the theory of pre-existent souls without a personal God. Many, if not most, of you probably possess more or less acquaintance with the views of my friend, Dr. McTaggart. I cannot here undertake a full exposition or criticism of one of the ablest thinkers of our day--one of the very few English thinkers who is the author of a truly original metaphysical system. I can only touch--and that most inadequately--upon the particular side of it which directly bears upon our present enquiry. Dr. McTaggart is an Idealist; he recognizes the {97} impossibility of matter without mind. For him nothing exists but spirits, but he does not recognize the necessity for any one all-embracing or controlling Spirit: the only spirits in his Universe are limited minds like those of men and animals. He differs, then, from the Pluralist of the type just mentioned in getting rid of the hypothesis of a personal God side by side with and yet controlling the uncreated spirits. And he differs further from all Pluralists in not treating the separate spirits as so many centres of consciousness quite independent of, and possibly at war with, all the rest: the spirits form part of an ordered system: the world is a unity, though that unity is not the unity which belongs to self-consciousness. He recognizes, in the traditional language of Philosophy, an Absolute, but this Absolute is not a single spiritual Being but a Society: or, if it is to be called a single spiritual Being, it is a Being which exists or manifests itself only in a plurality of limited consciousnesses.
