Kant, on the other hand, attacked and rejected Anselm’s proof—which rejection the whole world afterwards followed up—on the ground of its being an assumption that the unity of Being and thought is the highest perfection. What Kant thus demonstrates in the present day—that Being is different from thought and that Being is not by any means posited with thought—was a criticism offered even in that time by a monk named Gaunilo. He combated this proof of Anselm’s in a _Liber pro insipiente_ to which Anselm himself directed a reply in his _Liber apologeticus adversus insipientem_.[22] Thus Kant says (Kritik der reinen Vernunft, p. 464 of the sixth edition): If we think a hundred dollars, this conception does not involve existence. That is certainly true: what is only a conception does not exist, but it is likewise not a true content, for what does not exist, is merely an untrue conception. Of such we do not however here speak, but of pure thought; it is nothing new to say they are different—Anselm knew this just as well as we do. God is the infinite, just as body and soul, Being and thought are eternally united; this is the speculative, true definition of God. To the proof which Kant criticizes in a manner which it is the fashion to follow now-a-days, there is thus lacking only the perception of the unity of thought and of existence in the infinite; and this alone must form the commencement. Other proofs such, for example, as the cosmological, which argues from the contingency of the world to an absolute existence, have thereby not reached the idea of absolute essence as spirit, and are without consciousness of the fact that it is an object of thought. The old physico-theological proof, which even Socrates possessed, from beauty, order, organic ends, indeed implies an understanding, a richer thought of absolute existence, and not alone an indeterminate Being, but in this proof it likewise remains unknown that God is the Idea. And then what sort of an understanding is God? A different and immediate one; then this spirit is independent. Further, disorder likewise exists, and thus there must be something else conceived of than this apparent order of nature only. But from asking about the existence of God, from making his objective mode a predicate and thus knowing that God is Idea, to pass to making the absolute existence I = I, thinking self-consciousness, not as predicate but in such a way that each thinking I is the moment of this self-consciousness—is still a long stride. Here, where we see this form first emerge, absolute existence is clearly to be taken as the Beyond of finite consciousness; this is to itself the null and void, and it has not yet grasped its sense of self. Its thoughts regarding things are manifold, and the mere fact of being a thing is to it likewise just such a predicate as the rest; but it is thereby not yet turned back within itself, it knows of existence, but not of itself.
