ground upon which the purification takes place. "It is the purgatory between the Inferno of Sense and the Paradise of Reason." Its function is mediation; a continual degrading of the sensuous and external, and an elevation of the supersensual and internal. The transition of Religion into Speculative Philosophy is found in the mystics. Filled with the profound significance of religious symbolism, and seeing in it the explanation of the universe, they essay to communicate their insights. But the form of Science is not yet attained by them. They express themselves, not in those universal categories that the spirit of the race has formed in language for its utterance, but they have recourse to symbols more or less inadequate because ambiguous, and of insufficient universality to stand for the archetypes themselves. Thus "Becoming" is the most pure germinal archetype, and belongs therefore to logic, or the system of pure thought, and it has correspondences on concrete planes, as e.g., time, motion, life, &c. Now if one of these concrete terms is used for the pure logical category, we have mysticism. The alchemists, as shown by a genial writer of our day, use the technique of their craft to express the profound mysteries of spirit and its regeneration. The Eleusinian and other mysteries do the like.
While it is one of the most inspiring things connected with Speculative Philosophy to discover that the "Open Secret of the Universe" has been read by so many, and to see, under various expressions, the same meaning; yet it is the highest problem of Speculative Philosophy to seize a method that is adequate to the expression of the "Secret;" for its (the content's) own method of genetic development must be the only adequate one. Hence it is that we can classify philosophic systems by their success in seizing the content which is common to Art and Religion, as well as to Philosophy, in such a manner as to allow its free evolution and to have little in the method that is merely formal or extraneous to the idea itself. The rigid formalism of Spinoza—though manipulated by a clear speculative spirit—is inadequate to the unfolding of its content; for how could the mathematical method which is that of quantity or external determinations alone, ever suffice to unfold those first principles which attain to the quantitative only in their result? In this, the profoundest of subjects, we always find in Plato light for the way. Although he has not given us complete examples, yet he has pointed out the road of the true Speculative method in a way not to be mistaken. Instead of setting out with first principles presupposed as true, by which all is to be established, (as mathematics and such sciences do), he asserts that the first starting points must be removed as inadequate. We begin with the immediate, which is utterly insufficient, and exhibits itself as such. We ascend to a more adequate, by removing the first hypothesis; and this process repeats itself until we come to the first principle, which of course bears its own evidence in this, that it is absolutely universal and absolutely determined at the same time; in other words it is the self-determining, the "self-moved," as Plato and Aristotle call it. It is its own other, and hence it is the true infinite, for it is not limited but continued by its other.
From this peculiarity results the difficulty of Speculative Philosophy. The unused mind, accepting with naïveté the first proposition as settled, finds itself brought into confusion when this is contradicted, and condemns the whole procedure. The irony of Socrates, that always begins by positing the ground of his adversary, and reducing it through its own inadequateness to contradict itself, is of this character, and the unsophiscated might say, and do say: "See how illogical is Socrates, for he sets out to establish something, and arrives rather at the destruction of it." The reductio ad absurdum is a faint imitation of the same method. It is not sufficient to prove your own system by itself, for each of the opposing systems can do that; but you must show that any and all counter-hypotheses result in your own. God makes the wrath of men to praise Him, and all imperfect things must continually demonstrate the perfect, for the reason that they do not exist by reason of their defects, but through what of truth there is in them, and the imperfection is continually manifesting the want of the
