First of all, Hegel has to do utterly away with the sharing and partaking business he so much loathes. He will not call contradiction the glue in one place and identity in another; that is too half-hearted. Contradiction must be a glue universal, and must derive its credit from being shown to be latently involved in cases that we hitherto supposed to embody pure continuity. Thus, the relations of an ego with its objects, of one time with another time, of one place with another place, of a cause with its effect, of a thing with its properties, and especially of parts with wholes, must be shown to involve contradiction. Contradiction, shown to lurk in the very heart of coherence and continuity, cannot after that be held to defeat them, and must be taken as the universal solvent,—or, rather, there is no longer any need of a solvent. To 'dissolve' things in identity was the dream of earlier cruder schools. Hegel will show that their very difference is their identity, and that in the act of detachment the detachment is undone, and they fall into each other's arms.
Now, at the very outset it seems rather odd that a philosopher who pretends that the world is absolutely rational, or in other words that it can be completely understood, should fall back on a principle (the identity of contradictories) which utterly defies understanding, and obliges him in fact to use the word 'understanding,' whenever it occurs in his pages, as a term of contempt. Take the case of space we used above. The common man who looks at space believes there is nothing in it to be acquainted with beyond what he sees; no hidden machinery, no secrets, nothing but the parts as they lie side by side and make the static whole. His intellect is satisfied with accepting space as an ultimate genus of the given. But Hegel cries to him: "Dupe! dost thou not see it to be one nest of incompatibilities? Do not the unity of its wholeness and the diversity of its parts stand in patent contradiction? Does it not both unite and divide things; and but for this strange and irreconcilable activity, would it be at all? The hidden dynamism of self-contradiction is what incessantly produces the static appearance by which your sense is fooled."
But if the man ask how self-contradiction can do all this, and how its dynamism may be seen to work, Hegel can only reply by showing him the space itself and saying: "Lo, thus." In other words, instead of the principle of explanation being more intelligible than the thing to be explained, it is absolutely unintelligible if taken by itself, and must appeal to its pretended product to prove its existence. Surely, such a system of explaining notum per ignotum, of making the explicans borrow credentials from the explicand, and of creating paradoxes and impossibilities where none were suspected, is a strange candidate for the honor of being a complete rationalizer of the world.
The principle of the contradictoriness of identity and the identity of contradictories is the essence of the hegelian system. But what probably washes this principle down most with beginners is the combination in which its author works it with another principle which is by no means characteristic of his system, and which, for want of a better name, might be called the 'principle of totality.' This principle says that you cannot adequately know even a part until you know of what whole it forms a part. As Aristotle writes and Hegel loves to quote, an amputated hand is not even a hand. And as Tennyson says,—
"Little flower—but if I could understand
What you are, root and all, and all in all,
I should know what God and man is."
Obviously, until we have taken in all the relations, immediate or remote, into which the thing actually enters or potentially may enter, we do not know all about the thing.
And obviously for such an exhaustive acquaintance with the thing, an acquaintance with every other thing, actual and potential, near and remote, is needed; so that it is quite fair to say that omniscience alone can completely know any one thing as it stands. Standing in a world of relations, that world must be known before the thing is fully known. This doctrine is of course an integral part of empiricism, an integral part of common-sense. Since when could good men not apprehend the passing hour in the light of life's larger sweep,—not grow dispassionate the more they stretched their view? Did the 'law of sharing' so little legitimate their procedure that a law of identity of contradictories, forsooth, must be trumped up to give it scope? Out upon the idea!
Hume's account of causation is a good illustration of the way in which empiricism may use the principle of totality. We call something a cause; but we at the same time deny its effect to be in any latent way contained in or substantially identical with it. We thus cannot tell what its causality amounts to until its effect has actually supervened. The effect, then, or something beyond the thing is what makes the thing to be so far as it is a cause. Humism thus says that its causality is something adventitious and not necessarily given when its other attributes are there. Generalizing this, empiricism contends that we must everywhere distinguish between the intrinsic being of a thing and its relations, and, among these, between those that are essential to our knowing it at all and those that may be called adventitious. The thing as actually present in a given world is there with all its relations; for it to be known as it there exists, they must be known too, and it and they form a single fact for any consciousness large enough to embrace that world as a unity. But what constitutes this singleness of fact, this unity? Empiricism says, Nothing but the relation-yielding matrix in which the several items of the world find themselves embedded,—time, namely, and space, and the mind of the knower. And it says that were some of the items quite different from what they are and others the same, still, for aught we can see, an equally unitary world might be, provided each item were an object for consciousness and occupied a determinate point in space and time. All the adventitious relations would in such a world be changed, along with the intrinsic natures and places of the beings between which they obtained; but the 'principle of totality' in knowledge would in no wise be affected.
But Hegelism dogmatically denies all this to be possible. In the first place it says there are no intrinsic natures that may change; in the second it says there are no adventitious relations. When the relations of what we call a thing are told, no caput mortuum of intrinsicality, no 'nature,' is left. The relations soak up all there is of the thing; the 'items' of the world are but foci of relation with other foci of relation; and all the relations are necessary. The unity of the world has nothing to do with any 'matrix.' The matrix and the items, each with all, make a unity, simply because each in truth is all the rest. The proof lies in the hegelian principle of totality, which demands that if any one part be posited alone all the others shall forthwith emanate from it and infallibly reproduce the whole. In the modus operandi of the emanation comes in, as I said, that partnership of the principle of totality with that of the identity of contradictories which so recommends the latter to beginners in Hegel's philosophy. To posit one item alone is to deny the rest; to deny them is to refer to them; to refer to them is to begin, at least, to bring them on the scene; and to begin is in the fulness of time to end.
If we call this a monism, Hegel is quick to cry, Not so! To say simply that the one item is the rest of the universe is as false and one-sided as to say that it is simply itself. It is both and neither; and the only condition on which we gain the right to affirm that it is, is that we fail not to keep affirming all the while that it is not, as well. Thus the truth refuses to be expressed in any single act of judgment or sentence. The world appears as a monism and a pluralism, just as it appeared in our own introductory exposition.
