Inference
This is true of other inferences besides mathematical. They come to no definite conclusions about matters of fact, except as they are made effectual for their purpose by the living intelligence which uses them. "All men have their price; Fabricius is a man; he has his price;" but he had not his price; how is this? Because he is more than a universal; because he falls under other universals; because universals are ever at war with each other; because what is called a universal is only a general; because what is only general does not lead to a necessary conclusion. Let us judge him by another universal. "Men have a conscience; Fabricius is a man; he has a conscience." Until we have actual experience of Fabricius, we can only say, that, since he is a man, perhaps he will take a bribe, and perhaps he will not. "Latet dolus in generalibus;" they are arbitrary and fallacious, if we take them for more than broad views and aspects of things, serving as our notes and indications for judging of the particular, but not absolutely touching and determining facts.
Let units come first, and (so-called) universals second; let universals minister to units, not units be sacrificed to universals. John, Richard, and Robert are individual things, independent, incommunicable. We may find some kind of common measure between them, and we may give it the name of man, man as such, the typical man, the auto-anthropos. We are justified in so doing, and in investing it with general attributes, and bestowing on it what we consider a definition. But we think we may go on to impose our definition on the whole race, and to every member of it, to the thousand Johns, Richards, and Roberts who are found in it. No; each of them is what he is, in spite of it. Not any one of them is man, as such, or coincides with the auto-anthropos. Another John is not necessarily rational, because "all men are rational," for he may be an idiot;—nor because "man is a being of progress," does the second Richard progress, for he may be a dunce;—nor, because "man is made for society," must we therefore go on to deny that the second Robert is a gipsy or a bandit, as he is found to be. There is no such thing as stereotyped humanity; it must ever be a vague, bodiless idea, because the concrete units from which it is formed are independent realities. General laws are not inviolable truths; much less are they necessary causes. Since, as a rule, men are rational, progressive, and social, there is a high probability of this rule being true in the case of a particular person; but we must know him to be sure of it.
Each thing has its own nature and its own history. When the nature and the history of many things are similar, we say that they have the same nature; but there is no such thing as one and the same nature; they are each of them itself, not identical, but like. A law is not a fact, but a notion. "All men die; therefore Elias has died;" but he has not died, and did not die. He was an exception to the general law of humanity; so far, he did not come under that law, but under the law (so to say) of Elias. It was the peculiarity of his individuality, that he left the world without dying: what right have we to subject the person of Elias to the scientific notion of an abstract humanity, which we have formed without asking his leave? Why must the tyrant majority create a rule for his individual history? "But all men are mortal?" not so; what is really meant by this universal is, that "man, as such is mortal," that is, the abstract, typical auto-anthropos; to this major premiss the minor, if Elias is to be proved mortal, ought to be, "Elias was the abstract man;" but he was not, and could not be such, nor could any one else, any more than the average man of an Insurance Company is every individual man who insures his life with it. Such a syllogism proves nothing about the veritable Elias, except in the way of antecedent probability. If it be said that Elias was exempted from death, not by nature, but by miracle, what is this to the purpose, undeniable as it is? Still, to have this miraculous exemption was the personal prerogative of Elias. We call it miracle, because God ordinarily acts otherwise. He who causes men in general to die, gave to Elias not to die. This miraculous gift comes into the individuality of Elias. On this individuality we must fix our thoughts, and not begin our notion of him by ignoring it. He was a man, and something more than "man"; and if we do not take this into account, we fall into an initial error in our thoughts of him.
What is true of Elias is true of every one in his own place and degree. We call rationality the distinction of man, when compared with other animals. This is true in logic; but in fact a man differs from a brute, not in rationality only, but in all that he is, even in those respects in which he is most like a brute; so that his whole self, his bones, limbs, make, life, reason, moral feeling, immortality, and all that he is besides, is his real differentia, in contrast to a horse or a dog. And in like manner as regards John and Richard, when compared with one another; each is himself, and nothing else, and, though, regarded abstractedly, the two may fairly be said to have something in common, (viz., that abstract sameness which does not exist at all,) yet strictly speaking, they have nothing in common, for each of them has a vested interest in all that he himself is; and, moreover, what seems to be common in the two, becomes in fact so uncommon, so sui simile, in their respective individualities—the bodily frame of each is so singled out from all other bodies by its special constitution, sound or weak, by its vitality, activity, pathological history and changes, and, again, the mind of each is so distinct from all other minds, in disposition, powers, and habits,—that, instead of saying, as logicians say, that the two men differ only in number, we ought, I repeat, rather to say that they differ from each other in all that they are, in identity, in incommunicability, in personality.
Nor does any real thing admit, by any calculus of logic, of being dissected into all the possible general notions which it admits, nor, in consequence, of being recomposed out of them; though the attempt thus to treat it is more unpromising in proportion to the intricacy and completeness of its make. We cannot see through any one of the myriad beings which make up the universe, or give the full catalogue of its belongings. We are accustomed, indeed, and rightly, to speak of the Creator Himself as incomprehensible; and, indeed, He is so by an incommunicable attribute; but in a certain sense each of His creatures is incomprehensible to us also, in the sense that no one has a perfect understanding of them but He. We recognize and appropriate aspects of them, and logic is useful to us in registering these aspects and what they imply; but it does not give us to know even one individual being.
So much on logical argumentation; and in thus speaking of the syllogism, I speak of all inferential processes whatever, as expressed in language, (if they are such as to be reducible to science,) for they all require general notions, as conditions of their coming to a conclusion.
Thus, in the deductive argument, "Europe has no security for peace, till its large standing armies in its separate states are reduced; for a large standing army is in its very idea provocative of war," the conclusion is only probable, for it may so be that in no country is that pure idea realized, but in every country in concrete fact there may be circumstances, political or social, which destroy the abstract dangerousness.
