5. The doctrine of continuous Revelation through the Spirit is a part of Christianity, and the condition of its acceptance as the final or absolute Religion, . . . 185 {1} PHILOSOPHY AND RELIGION LECTURE I MIND AND MATTER I have been invited to speak to you about the relations between Religion and Philosophy. To do that in a logical and thoroughgoing way it would be necessary to discuss elaborately the meaning first of Religion and then of Philosophy. Such a discussion would occupy at least a lecture, and I am unwilling to spend one out of six scanty hours in formal preliminaries. I shall assume, therefore, that we all know in some general way the meaning of Religion. It is not necessary for our present purpose to discuss such questions as the definition of Religion for purposes of sociological investigation, or the possibility of a Religion without a belief in God, or the like. I shall assume that, whatever else may be included in the term Religion, Christianity may at least be included in it; and that what you are practically most interested in is the bearing of Philosophy upon the Christian ideas concerning the {2} being and nature of God, the hope of Immortality, the meaning and possibility of Revelation. When we turn to Philosophy, I cannot perhaps assume with equal confidence that all of you know what it is. But then learning what Philosophy is--especially that most fundamental part of Philosophy which is called Metaphysics--is like learning to swim: you never discover how to do it until you find yourself considerably out of your depth. You must strike out boldly, and at last you discover what you are after. I shall presuppose that in a general way you do all know that Philosophy is an enquiry into the ultimate nature of the Universe at large, as opposed to the discussion of those particular aspects or departments of it which are dealt with by the special Sciences. What you want to know, I take it, is--what rational enquiry, pushed as far as it will go, has to say about those ultimate problems of which the great historical Religions likewise profess to offer solutions. The nature and scope of Philosophy is best understood by examples: and therefore I hope you will excuse me if without further preface I plunge _in medias res_. I shall endeavour to presuppose no previous acquaintance with technical Philosophy, and I will ask those who have already made some serious study of Philosophy kindly to remember that I am trying to make myself intelligible to those who have not. I shall {3} not advance anything which I should not be prepared to defend even before an audience of metaphysical experts. But I cannot undertake in so short a course of lectures to meet all the objections which will, I know, be arising in the minds of any metaphysically trained hearers who may honour me with their presence, many of which may probably occur to persons not so trained.
