§ [164]. But it promises, furthermore, to remedy the defect common to these two doctrines, the very besetting problem of this whole type of philosophy. That problem, as has been seen, is to provide for the imperfect within the perfect, for the temporal incidents of nature and history within the eternal being. Many absolutist philosophers have declared the explanation of this realm to be impossible, and have contented themselves with calling it the realm of opinion or appearance. And this realm of opinion or appearance has been used as a proof of the absolute. Zeno, the pupil of Parmenides, was the first to elaborate what have since come to be known as the paradoxes of the empirical world. Most of these paradoxes turn upon the infinite extension and divisibility of space and time. Zeno was especially interested in the difficulty of conceiving motion, which involves both space and time, and thought himself to have demonstrated its absurdity and impossibility.[337:10] His argument is thus the complement of Parmenides's argument for the indivisible and unchanging substance. Now the method which Zeno here adopts may be extended to cover the whole realm of nature and history. We should then be dialectically driven from this realm to take refuge in absolute being. But the empirical world is not destroyed by disparagement, and cannot long lack champions even among the absolutists themselves. The reconciliation of nature and history with the absolute being became the special interest of Leibniz, the great modern Aristotelian. As a scientist and man of affairs, he was profoundly dissatisfied with Spinoza's resolution of nature, the human individual, and the human society into the universal being. He became an advocate of individualism while retaining the general aim and method of rationalism.
Like Aristotle, Leibniz attributes reality to individual substances, which he calls "monads"; and like Aristotle he conceives these monads to compose an ascending order, with God, the monad of monads, as its dominating goal.
"Furthermore, every substance is like an entire world and like a mirror of God, or indeed of the whole world which it portrays, each one in its own fashion; almost as the same city is variously represented according to the various situations of him who is regarding it. Thus the universe is multiplied in some sort as many times as there are substances, and the glory of God is multiplied in the same way by as many wholly different representations of his works."[338:11]
The very "glory of God," then, requires the innumerable finite individuals with all their characteristic imperfections, that the universe may lack no possible shade or quality of perspective.
The Problem of Imperfection Remains Unsolved.
§ [165]. But the besetting problem is in fact not solved, and is one of the chief incentives to that other philosophy of absolutism which defines an absolute spirit or mind. Both Aristotle and Leibniz undertake to make the perfection which determines the order of the hierarchy of substances, at the same time the responsible author of the whole hierarchy. In this case the dilemma is plain. If the divine form or the divine monad be other than the stages that lead up to it, these latter cannot be essential to it, for God is by definition absolutely self-sufficient. If, on the other hand, God is identical with the development in its entirety, then two quite incommensurable standards of perfection determine the supremacy of the divine nature, that of the whole and that of the highest parts of the whole. The union of these two and the definition of a perfection which may be at once the development and its goal, is the task of absolute idealism.
Absolute Realism in Epistemology. Rationalism.
§ [166]. Of the two fundamental questions of epistemology, absolute realism answers the one explicitly, the other implicitly. As respects the source of the most valid knowledge, Parmenides, Plato, Aristotle, Spinoza are all agreed: true knowledge is the work of reason, of pure intellection. Plato is the great exponent of dialectic, or the reciprocal affinities and necessities of ideas. Aristotle is the founder of deductive logic. Spinoza proposes to consider even "human actions and desires" as though he were "concerned with lines, planes, and solids." Empirical data may be the occasion, but cannot be the ground of the highest knowledge. According to Leibniz,
"it seems that necessary truths, such as we find in pure mathematics, and especially in arithmetic and geometry, must have principles whose proof does not depend upon instances, nor, consequently, upon the witness of the senses, although without the senses it would never have come into our heads to think of them."[340:12]
