remarks, and in particular to define some of the terms which I shall have occasion to use in the lectures. I have defined natural theology as that reasoned knowledge of a God or gods which man may be supposed, whether rightly or wrongly, capable of attaining to by the exercise of his natural faculties alone. Whether there ever has been or can be a special miraculous revelation of God to man through channels different from those through which all other human knowledge is derived, is a question which does not concern us in these lectures; indeed it is expressly excluded from their scope by the will of the founder, who directed the lecturers to treat the subject "as a strictly natural science," "without reference to or reliance upon any supposed special exceptional or so-called miraculous revelation." Accordingly, in compliance with these directions, I dismiss at the outset the question of a revelation, and shall limit myself strictly to natural theology in the sense in which I have defined it.
Theology and religion, how related to each other.
I have called natural theology a reasoned knowledge of a God or gods to distinguish it from that simple and comparatively, though I believe never absolutely, unreasoning faith in God which suffices for the practice of religion. For theology is at once more and less than religion: if on the one hand it includes a more complete acquaintance with the grounds of religious belief than is essential to religion, on the other hand it excludes the observance of those practical duties which are indispensable to any religion worthy of the name. In short, whereas theology is purely theoretical, religion is both theoretical and practical, though the theoretical part of it need not be so highly developed as in theology. But while the subject of the lectures is, strictly speaking, natural theology rather than natural religion, I think it would be not only difficult but undesirable to confine our attention to the purely theological or theoretical part of natural religion: in all religions, and not least in the undeveloped savage religions with which we shall deal, theory and practice fuse with and interact on each other too closely to be forcibly disjoined and handled apart. Hence throughout the lectures I shall not scruple to refer constantly to religious practice as well as to religious theory, without feeling that thereby I am transgressing the proper limits of my subject.
The term God defined.
As theology is not only by definition but by etymology a reasoned knowledge or theory of a God or gods, it becomes desirable, before we proceed further, to define the sense in which I understand and shall employ the word God. That sense is neither novel nor abstruse; it is simply the sense which I believe the generality of mankind attach to the term. By a God I understand a superhuman and supernatural being, of a spiritual and personal nature, who controls the world or some part of it on the whole for good, and who is endowed with intellectual faculties, moral feelings, and active powers, which we can only conceive on the analogy of human faculties, feelings, and activities, though we are bound to suppose that in the divine nature they exist in higher degrees, perhaps in infinitely higher degrees, than the corresponding faculties, feelings, and activities of man. In short, by a God I mean a beneficent supernatural spirit, the ruler of the world or of some part of it, who resembles man in nature though he excels him in knowledge, goodness, and power. This is, I think, the sense in which the ordinary man speaks of a God, and I believe that he is right in so doing. I am aware that it has been not unusual, especially perhaps of late years, to apply the name of God to very different conceptions, to empty it of all implication of personality, and to reduce it to signifying something very large and very vague, such as the Infinite or the Absolute (whatever these hard words may signify), the great First Cause, the Universal Substance, "the stream of tendency by which all things seek to fulfil the law of their being,"1 and so forth. Now without expressing any opinion as to the truth or falsehood of the views implied by such applications of the name of God, I cannot but regard them all as illegitimate extensions of the term, in short as an abuse of language, and I venture to protest against it in the interest not only of verbal accuracy but of clear thinking, because it is apt to conceal from ourselves and others a real and very important change of thought: in particular it may lead many to imagine that the persons who use the name of God in one or other of these extended senses retain certain theological opinions which they may in fact have long abandoned. Thus the misuse of the name of God may resemble the stratagem in war of putting up dummies to make an enemy imagine that a fort is still held after it has been evacuated by the garrison. I am far from alleging or insinuating that the illegitimate extension of the divine name is deliberately employed by theologians or others for the purpose of masking a change of front; but that it may have that effect seems at least possible. And as we cannot use words in wrong senses without running a serious risk of deceiving ourselves as well as others, it appears better on all accounts to adhere strictly to the common meaning of the name of God as signifying a powerful supernatural and on the whole beneficent spirit, akin in nature to man; and if any of us have ceased to believe in such a being we should refrain from applying the old word to the new faith, and should find some other and more appropriate term to express our meaning. At all events, speaking for myself, I intend to use the name of God consistently in the familiar sense, and I would beg my hearers to bear this steadily in mind.
Monotheism and polytheism.
You will have observed that I have spoken of natural theology as a reasoned knowledge of a God or gods. There is indeed nothing in the definition of God which I have adopted to imply that he is unique, in other words, that there is only one God rather than several or many gods. It is true that modern European thinkers, bred in a monotheistic religion, commonly overlook polytheism as a crude theory unworthy the serious attention of philosophers; in short, the champions and the assailants of religion in Europe alike for the most part tacitly assume that there is either one God or none. Yet some highly civilised nations of antiquity and of modern times, such as the ancient Egyptians, Greeks, and Romans, and the modern Chinese and Hindoos, have accepted the polytheistic explanation of the world, and as no reasonable man will deny the philosophical subtlety of the Greeks and the Hindoos, to say nothing of the rest, a theory of the universe which has commended itself to them deserves perhaps more consideration than it has commonly received from Western philosophers; certainly it cannot be ignored in an historical enquiry into the origin of religion.
A natural knowledge of God can only be acquired by experience.
If there is such a thing as natural theology, that is, a knowledge of a God or gods acquired by our natural faculties alone without the aid of a special revelation, it follows that it must be obtained by one or other of the methods by which all our natural knowledge is conveyed to us. Roughly speaking, these methods are two in number, namely, intuition and experience. Now if we ask ourselves, Do we know God intuitively in the same sense in which we know intuitively our own sensations and the simplest truths of mathematics, I think most men will acknowledge that they do not. It is true that according to Berkeley the world exists only as it is perceived, and that our perceptions of it are produced by the immediate action of God on our minds, so that everything we perceive might be described, if not as an idea in the mind of the deity, at least as a direct emanation from him. On this theory we might in a sense be said to have an immediate knowledge of God. But Berkeley's theory has found little acceptance, so far as I know, even among philosophers; and even if we regarded it as true, we should still have to admit that the knowledge of God implied by it is inferential rather than intuitive in the strict sense of the word: we infer God to be the cause of our perceptions rather than identify him with the perceptions themselves. On the whole, then, I conclude that man, or at all events the ordinary man, has, properly speaking, no immediate or intuitive knowledge of God, and that, if he obtains, without the aid of revelation, any knowledge of him at all, it can only be through the other natural channel of knowledge, that is, through experience.
The nature of experience.
In experience, as distinct from intuition, we reach our conclusions not directly through simple contemplation of the particular sensations, emotions, or ideas of which we are at the moment conscious, but indirectly by calling up before the imagination and comparing with each other our memories of a variety of sensations, emotions, or ideas of which we have been conscious in the past, and by selecting
