at all. But if, again, the external fact of A’s and B’s conjunction is offered as a reason, then that conjunction itself creates the same difficulty. For thought’s analysis can respect nothing, nor is there any principle by which at a certain point it should arrest itself or be arrested. Every distinguishable aspect becomes therefore for thought a diverse element to be brought to unity. Hence thought can no more pass without a reason from A or from B to its conjunction, than before it could pass groundlessly from A to B. The transition, being offered as a mere datum, or effected as a mere fact, is not thought’s own self-movement. Or in other words, because for thought no ground can be merely external, the passage is groundless. Thus A and B and their conjunction are, like atoms, pushed in from the outside by chance or fate; and what is thought to do with them but either make or accept an arrangement which to it is wanton and without reason,—or, having no reason for anything else, attempt against reason to identify them simply?
“This is not so,” I shall be told, “and the whole case is otherwise. There are certain ultimate complexes given to us as facts, and these ultimates, as they are given, thought simply takes up as principles and employs them to explain the detail of the world. And with this process thought is satisfied.” To me such a doctrine is quite erroneous. For these ultimates (a) cannot make the world intelligible, and again (b) they are not given, and (c) in themselves they are self-contradictory, and not truth but appearance.
Certainly for practice we have to work with appearance and with relative untruths, and without these things the sciences of course would not exist. There is, I suppose, here no question about all this, and all this is irrelevant. The question here is whether with so much as this the intellect can be satisfied, or whether on the other hand it does not find in the end defect and self-contradiction. Consider first (a) the failure of what is called “explanation.” The principles taken up are not merely in themselves not rational, but, being limited, they remain external to the facts to be explained. The diversities therefore will only fall, or rather must be brought, under the principle. They do not come out of it, nor of themselves do they bring themselves under it. The explanation therefore in the end does but conjoin aliens inexplicably. The obvious instance is the mechanical interpretation of the world. Even if here the principles were rational intrinsically, as surely they are not, they express but one portion of a complex whole. The rest therefore, even when and where it has been “brought under” the principles, is but conjoined with them externally and for no known reason. Hence in the explanation there is in the end neither self-evidence nor any “because” except that brutally things come so.
