You pretend that we are not able to form any conception of “ever‐lasting” or “infinite”; and, to prove this, you affirm that “our understanding, being limited by time and space, finds an impassable barrier for that conception.” Very well; but what did you mean when you contended that matter is “eternal” and “infinite”? Had you then any conception of “eternal” and “infinite”? If you had not such conceptions, you made a fool of yourself by using terms which you did not understand; while, if you had such conceptions, then it is false that we are not able to form them. In the same manner, have you any conception of the “absolute”? If you have it, then it is ridiculous to pretend that we cannot conceive the absolute; while, if you have it not, you know not about what you are speaking. Alas! poor doctor. What can you answer? It is the common fate of the enemies of truth to be inconsistent with themselves, and to demolish with one hand what they build with the other. But is it true that our intellect “is limited by time and space”? No, it is not true. Imagination is indeed limited by time and space, as all our philosophers concede; but intellect understands things independently of either space or time. This is evident. For in what space do we place the universals? To what time do we confine mathematical truths? _Two and two are known to make four_ in all places and in all times—that is, without restriction or limit in space and time; and the same is true of all intellectual principles. Hence it is obvious that our understanding transcends both space and time, and can reach the infinite and the eternal. It is through abstraction, of course, and not by comprehension or by intuition, that we form such notions; for our intellect, though not limited by time and space, is limited in its own entity, and therefore it cannot conceive the unlimited, except by the help of the abstractive process—that is, by removing the limits by which the objective reality of the finite is circumscribed. That we can do this I need not prove _to you;_ for you admit that space is infinite, and pretend that matter itself is infinite, as I have just remarked; and consequently you cannot deny that we have the notion of infinity.
