I

Those responsible for the selection of Gifford Lecturers have made it clear that, in their interpretation of Lord Gifford’s Trust, studies in a very wide range of subjects are relevant to the theme of Natural Religion. Gifford lectures have been devoted to such diverse themes as Comparative Religion, Primitive Mythologies, Vitalism, Psychology of Religious Experiences, the History of Religious Development at particular Epochs. And, in addition to these, we have had expounded to us systems of Metaphysics of more than one type, and drawing their inspiration from more than one school.

When I was honoured by an invitation to take a share in the perennial debate which centres round what Lord Gifford described as Natural Religion, I had to consider what kind of contribution I was least unfitted to make. Perhaps if this consideration had preceded my reply to the invitation, instead of following it, I might have declined the perilous honour. Neither in my own opinion nor in that of anybody else, am I qualified to contribute a special study of any of the scientific, psychological, anthropological, or historical problems which may throw light upon the central issue. This must of necessity be the work of specialists. No metaphysical system, again, am I in a position to provide;—for reasons which will appear in the sequel. A merely critical commentary upon the systems of other people might hardly meet either the expectations of my audience, or the wishes of those who appointed me to the post. Indeed, the enormous range of modern philosophic literature, and the divergent tendencies of modern philosophic thought would make the task, in any case, one of extreme difficulty. Few, indeed, are those who, by the width of their reading and the quickness of their intellectual sympathy, are qualified to survey the whole field of contemporary speculation; and, assuredly, I am not among them.

The vast amplitude of relevant material daily growing with the growth of knowledge, cannot but hamper the sincerest efforts of those who desire to take a comprehensive view of the great problems which Lord Gifford desired to solve. Most men are amateurs in all departments of activity but the one, be it scientific or practical, or artistic, to which they have devoted their lives. Bacon, indeed, with the magnificent audacity of youth, took all knowledge for his province. But he did so in the sixteenth century, not in the twentieth; and even Bacon did not escape the charge of being an amateur. No one, while human faculty remains unchanged, is likely to imitate his ambitions. More and more does the division and subdivision of labour become necessary for knowledge, as for industry. More and more have men to choose whether they shall be dabblers in many subjects or specialists in one. More and more does it become clear that, while each class has its characteristic defects, both are required in the republic of knowledge.

So far as specialists are concerned, this last proposition is self-evident. Specialists are a necessity. And it may well be that those who have successfully pressed forward the conquering forces of discovery along some narrow front, careless how the struggle towards enlightenment fared elsewhere, may be deemed by the historian to have been not only the happiest, but the most useful thinkers of their generation. Their achievements are definite. Their contributions to knowledge can be named and catalogued. The memory of them will remain when contemporary efforts to reach some general point of view will seem to posterity strangely ill-directed, worthless to all but the antiquarian explorers of half-forgotten speculation.

Yet such efforts can never be abandoned, nor can they be confined to philosophers. There are for all men moments when the need for some general point of view becomes insistent; when neither labour, nor care, nor pleasure, nor idleness, nor habit will stop a man from asking how he is to regard the universe of reality, how he is to think of it as a whole, how he is to think of his own relation to it.

Now I have no wish to overpraise these moments of reflection. They are not among the greatest. They do not of necessity involve strenuous action, or deep emotion, or concentrated thought. Often they are periods of relaxation rather than of tension, moods that pass and leave no trace. Yet it is not always so; and when the pressure of these ancient problems becomes oppressive, then those who, from taste or necessity, have lived only from hour to hour, seek aid from those who have had leisure and inclination to give them a more prolonged consideration.

Of these there is no lack; some speaking in the name of science, some in the name of religion, some in the name of philosophy. The founder of these lectures regarded philosophy, and (if I mistake not) philosophy in its most metaphysical aspect, as the surest guide to the truths of which he was in search. And certainly I am the last to criticise such a view. It is clearly the business of metaphysicians, if they have any business at all, to provide us with a universal system. They cannot lose themselves in concrete details, as may happen to men of science. They are neither aided, nor trammelled, as all working organisations, whether in Church or State, are necessarily aided and trammelled, by institutional traditions and practical necessities. They exist to supply answers to the very questions of which I have been speaking. Yet metaphysics does not appeal, and has never appealed, to the world at large. For one man who climbs to his chosen point of view by a metaphysical pathway, a thousand use some other road; and if we ask ourselves how many persons there are at this moment in existence whose views of the universe have been consciously modified by the great metaphysical systems (except in so far as these have been turned to account by theologians), we must admit that the number is insignificant.

Now, I do not think this is due to the fact, so often commented upon, both by the friends of metaphysics and its foes, that in this branch of inquiry there is little agreement among experts; that the labours of centuries have produced no accepted body of knowledge; that, while the separate sciences progress, metaphysics, which should justify them all, seems alone to change without advancing. Mankind is not so easily discouraged. New remedies are not less eagerly adopted because old remedies have so often failed. Few persons are prevented from thinking themselves right by the reflection that, if they be right, the rest of the world is wrong. And were metaphysical systems what men wanted, the disagreements among metaphysicians would no more destroy interest in metaphysics than the disagreements among theologians destroys interest in theology. The evil, if evil it be, lies deeper. It is not so much that mankind reject metaphysical systems, as that they omit the preliminary stage of considering them. Philosophy is now, perhaps has always been, an academic discipline which touches not our ordinary life. A general knowledge of the historic schools of thought may indeed be acquired by the young as part of their education; but it is commonly forgotten by the middle-aged; and, whether forgotten or remembered, is rarely treated as in any vital relation to the beliefs and disbeliefs which represent their working theories of life and death.

If you desire confirmation of this statement, consider how few men of science have shown the smallest interest in metaphysical speculation. Philosophers, with one or two notorious exceptions, have commonly had a fair amateur acquaintance with the science of their day. Kant, though I believe that his mechanics were not always beyond reproach, anticipated Laplace in one famous hypothesis. Descartes and Leibnitz would be immortalised as mathematicians if they had never touched philosophy, and as philosophers if they had never touched mathematics. In our own day Huxley not only contributed to biology, but wrote on philosophy. Yet, speaking generally, metaphysics has in modern times been treated by men of science with an indifference which is sometimes respectful, more commonly contemptuous, almost always complete.
