But what if the "delighted spirit" has been developed by brain, and with brain must be dissolved? Our whole distinctive human life, our mind, moral, intellectual, spiritual, rebels against a doom of subjection to that crass material law! Yet can we establish a difference? Can we show that the law of our true being differs from the law of things outside us?
This question, unspeakably interesting to every one of us, might be put in various shapes. We might ask, Can the protest of soul be set down as a mere sentiment only? If it were no more than an instinct of our nature, it would deserve consideration; for why should so high and noble an instinct be aimless and misleading? If we cannot trust our own souls, what are we to trust? Phenomena themselves are given us within. Mathematical truths, which Positivists are obliged to exempt from phenomenal law, have a subjective validity—we cannot help thinking them, and we cannot think their contradictories.
But suppose that a future state of recompence with its inferential moralities cannot be denied without denying our own consciousness—pronouncing the clearest of our intuitions a will o' the wisp—or, sadder still, a corpse light on the grave of hope—nay, more, without subverting the law which makes human society to differ from animal gregariousness, and gives to human action its spring, its liberty, its life—suppose all this true, what shall, what can we say? And such is the issue I propose to try this morning.
The plan I have devised for trying it fairly is, first, to get as clear an idea as short compass will allow of what Positivism says on our question. Afterwards to state a case for moral law by way of antithesis. It is through the law of our moral being that we may most readily look for something to difference our souls from creatures below them. The strain I shall have to put on your attention lies in this; after grasping in brief the Positivist attitude, I must ask that you will not take my facts or arguments on trust, but will verify each severally by an appeal to your own consciousness. It is always upon the law deduced from or applied to facts that you ought to exercise your greatest vigilance. For law interprets facts to us—we might almost say that under its manipulation they bend like a nose of wax; nothing, you will remember, so flexible as figures, except facts.
Let me represent these maxims to you under a similitude. Everybody has looked (when young at least) through a kaleidoscope, and has observed the beauty of its many-coloured figures, their symmetrical shapes, and the enchantment of their succession. What magic creates this phantasmagoria? Some pretty bits of coloured glass, shining gewgaws, scraps of lace, fripperies, and other odds and ends, are put into a translucent box, and beheld through a tube fitted with mirrors which are set at an angle determined by optical law. The broken knick-knacks represent the facts of everybody's phenomenal kaleidoscope; the reflecting angle under which they are seen is its law; the coloured images are everybody's impressions of things, nature, and mankind. As long as you live, remember that whenever you are contemplating the world's phenomena—whenever you see facts of life, either great or small, you are looking at them through some optical instrument or another. If its law accords with their law, your view is truthful; but then it will be all the less pretty, the less symmetrical. There are dark spots in our real world, checks of all sorts, moral evil, anguish of heart and conscience, foresights, stern accountabilities! You have lost your childhood's magic glass, and have got a clear reflecting telescope in its stead! Pity to forego the nice kaleidoscope where all was so bright, so harmonious, and arrayed in such regular shapes. Yet the view it gave was worth what most people's views are worth—precisely nothing!
Comte had his kaleidoscope. Every systematizer who allows no mystery, no darkness anywhere, must keep the article; in point of fact, most people enjoy having one. Alas! for the 19th century! It has such a feverish viewiness, such a fashion of incessantly turning its magic tube, that life seems little else than a dreamy phantasmagoria! To construct a steady reflecting instrument for yourself requires industry, time, and thought, three things which few people care to bestow upon their beliefs. Therefore the practice is to pick up kaleidoscopes ready-made at a cheap rate, and to feel as easy as stern realities will permit on the subject of their truthfulness. Romances are the kaleidoscopes of one class, cram-books of a second, newspapers of a third, self-love the optical law of the greatest number. We are met this morning to break up a grand kaleidoscope, and to look into its construction. I shall do my endeavour to prevent you all from replacing it by any instrument of a ready-made sort. The easiest plan for all lecturers is to display a series of transparent conclusions; but I shall prefer furnishing you with facts and arguments, letting you put them together, look at them, and verify their law of true vision for yourselves.
Let us see Comte's law first. It was, strictly speaking, a law of succession and resemblance. You will guess at once that were this all we could see in the phenomenal world, our insight would be very limited. And Comte's object was to limit us. We can never know, Positively speaking, final causes; those which make up the common notion of design, purpose, intention. Nor yet any efficient causes; nothing truly productive of an effect, as men usually say. All we can know is the middle of a chain of successive phenomena. The two ends are absolutely hidden from our eyes. It was in this sense that Comte denied causation—his language was vigorous; he denounced it as metaphysical, and when Comte nicknames anything metaphysical or theological, he means, as everybody knows, Anathema maranatha.
The difficulty here is palpable. A law of averages—a statistical law, as it is often called, does not profess to account for anything; it merely generalizes crude material, and gets it ready for scientific thought to work out the true law. But a law of succession has an imposing sound, and it does in the worst sense impose. The fallacy may be shown in an instant. Day and night succeed each other regularly. Does either account for the other? The rotation of the earth is simultaneous with both—it accounts for both. Its effect is to expose the earth's two hemispheres alternately to the sun's rays. This rotation coincides again with other laws of our planetary system, and they account for it. It is on these laws, and not on such grounds as Hume, Comte's great Positive antecedent, alleged, that we look for sunset and sunrise. When they fail, the system of which our globe forms part will have collapsed.
Such then was the original kaleidoscope of Positivism. It was condemned for reasons which will have plainly appeared to you. Other eyes have swept the field of vision this world offers, and other instruments to aid our insight have been adopted.
You will not have failed already to remark the extreme vagueness of that word "law." There are very few English words more vague: it is applied to almost every sort of formula, force, principle, idea; besides being misused in ways almost innumerable. You must therefore, when busy with questions like the present, fix your attention upon the adjectives added to it, and the examples selected by way of illustration.
