is the result of some sort of general or universal motion, and that it thus falls under the same head as other motions, either those which originate in ourselves and are propagated from our bodies to external objects, or those which, springing from an unknown beginning, are for ever continuing as before.

This then is the answer to the question, Why do we believe in the uniformity of Nature? We believe in it because we find it so. Millions on millions of observations concur in exhibiting this uniformity. And the longer our observation of Nature goes on, the greater do we find the extent of it. Things that once seemed irregular are now known to be regular. Things that seemed inexplicable on this hypothesis are now explained. Every day seems to add not merely to the instances but to the wide-ranging classes of phenomena that come under the rule. We had reason long ago to hold that the quantity of matter was invariable. We now have reason to think that the quantity of force acting on matter is invariable. And to this is to be added the evidence of scientific prediction, the range of which is perpetually increasing, and which would be obviously impossible if Nature were not uniform. And yet again to this is to be added that this uniformity does not consist in a vast number of separate and independent laws, but that these laws already form a system with one another, and that that system is daily becoming more complete. We believe in the uniformity of Nature because, as far as we can observe it, that is the character of Nature.

And I use the word character on purpose, because it indicates better than any other word that I could find at once the nature and limitation of our belief.

For, if the origin of this belief be what I have described, it is perfectly clear that, however vast may be the evidence to prove this uniformity, the conclusion can never go beyond the limits of this evidence, and generality can never be confounded with universality. The certainty that Nature is uniform is not at all, and never can be, a certainty of the same kind as the certainty that four times five are twenty.

We can assert that the general character of Nature is uniformity, but we cannot go beyond this. Every separate law of nature is established by induction from the facts, and so too is the general uniformity. Every separate law of Nature is a working hypothesis. So too is the uniformity of Nature a working hypothesis, and it never can be more. It is true that there is far more evidence for the uniformity of Nature as a whole than for any one law of Nature; because a law of Nature is established by the uniformity of sequences in those phenomena to which it applies; whereas every uniformity of sequence, of whatever kind, is an evidence of the general uniformity. The evidence for the uniformity of nature is the accumulated evidence for all the separate uniformities. But, however much greater the quantity of evidence, the kind ever remains the same. There is no means by which we can demonstrate this uniformity. We can only make it probable. We can say that in almost every case all the evidence is one way; but whenever there is evidence to the contrary we cannot refuse to examine it.

If a miracle were worked science could not prove that it was a miracle, nor of course prove that it was not a miracle. To prove it to be a miracle would require not a vast range of knowledge, but absolutely universal knowledge, which it is entirely beyond our faculties to attain. To say that any event was a miracle would be to say that we knew that there was no higher law that could explain it, and this we could not say unless we knew all laws: to say that it was not a miracle would be ex hypothesi to assert what was false. In fact, to assert the occurrence of a miracle is simply to go back to the beginning of science, and to say: Here is an event which we cannot assign to that derivative action to which we have been led to assign the great body of events; we cannot explain it except by referring it to direct and spontaneous action, to a will like our own will. Science has shown that the vast majority of events are due to derivative action regulated by laws. Here is an event which cannot be so explained, any more than the action of our own free will can be so explained. Science may fairly claim to have shown that miracles, if they happen at all, are exceedingly rare. To demonstrate that they never happen at all is impossible, from the very nature of the evidence on which Science rests. But for the same reason Science can never in its character of Science admit that a miracle has happened. Science can only admit that, so far as the evidence goes, an event has happened which lies outside its province.

To believers the progress of Science is a perpetual instruction in the character which God has impressed on His works. That He has put Order in the very first place may be a surprise to us; but it can only be a surprise. In the great machinery of the Universe it constantly happens to us to find that that which is made indispensable, is nevertheless not the highest. The chosen people were not the highest in all moral or even in all spiritual characteristics; if we refuse the explanation given by Goethe that they were chosen for their toughness, yet we have no better to give. The eternal moral law is of all we know the highest and holiest. Yet the religious instinct seems to have been more indispensable for the development of humanity according to the Divine purpose than the observance of that moral law in all its fulness. It would never have occurred to us beforehand to permit in Divine legislation any concession to the hardness of men's hearts; yet we know that it was done. Science now tells us that Order takes a rank in God's work far above where we should have placed it. It is not the highest; it is far from the highest: but it appears to be in some strange way the most indispensable. God is teaching us that Order is far more universal, far more penetrating than we should have supposed. But, nevertheless, it is not itself God; nor the highest revelation of God. It is the stamp which, for reasons higher than itself, He appears to have put on His works. What is the limit to its application we do not know. There may be instances where this Order is apparently broken, but really maintained, because one physical law is absorbed in a higher; there may be instances where the physical law is superseded by a moral law. But we shall neither refuse to recognise that God has stamped this character on His works, nor let it on the other hand come between us and Him. For we know still that He is greater than all that He hath made, and He speaks to us by another voice besides the voice of Science.

THE ORIGIN AND NATURE OF RELIGIOUS BELIEF.

The voice within. The objection of the alleged relativity of knowledge. Absolute knowledge of our own personal identity. Failure to show this to be relative; in particular by Mr. Herbert Spencer. The Moral Law. The command to live according to that Law; Duty. The command to believe in the supremacy of that Law; the lower Faith. The Last Judgment. The hope of Immortality. The personification of the Moral Law in Almighty God; the higher Faith. The spiritual faculty the recipient of Revelation, if any be made. The contrast between Religion and Science.
