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 {277} 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 {278} 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!
