Subsequently reason—that is, philosophy—took possession of this God who had arisen in the human consciousness as a consequence of the sense of divinity in man, and tended to define him and convert him into an idea. For to define a thing is to idealize it, a process which necessitates the abstraction from it of its incommensurable or irrational element, its vital essence. Thus the God of feeling, the divinity felt as a unique person and consciousness external to us, although at the same time enveloping and sustaining us, was converted into the idea of God.
The logical, rational God, the ens summum, the primum movens, the Supreme Being of theological philosophy, the God who is reached by the three famous ways of negation, eminence and causality, viæ negationis, eminentiæ, causalitatis, is nothing but an idea of God, a dead thing. The traditional and much debated proofs of his existence are, at bottom, merely a vain attempt to determine his essence; for as Vinet has very well observed, existence is deduced from essence; and to say that God exists, without saying what God is and how he is, is equivalent to saying nothing at all.
And this God, arrived at by the methods of eminence and negation or abstraction of finite qualities, ends by becoming an unthinkable God, a pure idea, a God of whom, by the very fact of his ideal excellence, we can say that he is nothing, as indeed he has been defined by Scotus Erigena: Deus propter excellentiam non inmerito nihil vocatur. Or in the words of the pseudo-Dionysius the Areopagite, in his fifth Epistle, "The divine darkness is the inaccessible light in which God is said to dwell." The anthropomorphic God, the God who is felt, in being purified of human, and as such finite, relative and temporal, attributes, evaporates into the God of deism or of pantheism.
The traditional so-called proofs of the existence of God all refer to this God-Idea, to this logical God, the God by abstraction, and hence they really prove nothing, or rather, they prove nothing more than the existence of this idea of God.
In my early youth, when first I began to be puzzled by these eternal problems, I read in a book, the author of which I have no wish to recall,[39] this sentence: "God is the great X placed over the ultimate barrier of human knowledge; in the measure in which science advances, the barrier recedes." And I wrote in the margin, "On this side of the barrier, everything is explained without Him; on the further side, nothing is explained, either with Him or without Him; God therefore is superfluous." And so far as concerns the God-Idea, the God of the proofs, I continue to be of the same opinion. Laplace is said to have stated that he had not found the hypothesis of God necessary in order to construct his scheme of the origin of the Universe, and it is very true. In no way whatever does the idea of God help us to understand better the existence, the essence and the finality of the Universe.
That there is a Supreme Being, infinite, absolute and eternal, whose existence is unknown to us, and who has created the Universe, is not more conceivable than that the material basis of the Universe itself, its matter, is eternal and infinite and absolute. We do not understand the existence of the world one whit the better by telling ourselves that God created it. It is a begging of the question, or a merely verbal solution, intended to cover up our ignorance. In strict truth, we deduce the existence of the Creator from the fact that the thing created exists, a process which does not justify rationally His existence. You cannot deduce a necessity from a fact, or else everything were necessary.
And if from the nature of the Universe we pass to what is called its order, which is supposed to necessitate an Ordainer, we may say that order is what there is, and we do not conceive of any other. This deduction of God's existence from the order of the Universe implies a transition from the ideal to the real order, an outward projection of our mind, a supposition that the rational explanation of a thing produces the thing itself. Human art, instructed by Nature, possesses a conscious creative faculty, by means of which it apprehends the process of creation, and we proceed to transfer this conscious and artistic creative faculty to the consciousness of an artist-creator, but from what nature he in his turn learnt his art we cannot tell.
The traditional analogy of the watch and the watchmaker is inapplicable to a Being absolute, infinite and eternal. It is, moreover, only another way of explaining nothing. For to say that the world is as it is and not otherwise because God made it so, while at the same time we do not know for what reason He made it so, is to say nothing. And if we knew for what reason God made it so, then God is superfluous and the reason itself suffices. If everything were mathematics, if there were no irrational element, we should not have had recourse to this explanatory theory of a Supreme Ordainer, who is nothing but the reason of the irrational, and so merely another cloak for our ignorance. And let us not discuss here that absurd proposition that, if all the type in a printing-press were printed at random, the result could not possibly be the composition of Don Quixote. Something would be composed which would be as good as Don Quixote for those who would have to be content with it and would grow in it and would form part of it.
In effect, this traditional supposed proof of God's existence resolves itself fundamentally into hypostatizing or substantivating the explanation or reason of a phenomenon; it amounts to saying that Mechanics is the cause of movement, Biology of life, Philology of language, Chemistry of bodies, by simply adding the capital letter to the science and converting it into a force distinct from the phenomena from which we derive it and distinct from our mind which effects the derivation. But the God who is the result of this process, a God who is nothing but reason hypostatized and projected towards the infinite, cannot possibly be felt as something living and real, nor yet be conceived of save as a mere idea which will die with us.
The question arises, on the other hand, whether a thing the idea of which has been conceived but which has no real existence, does not exist because God wills that it should not exist, or whether God does not will it to exist because, in fact, it does not exist; and, with regard to the impossible, whether a thing is impossible because God wills it so, or whether God wills it so because, in itself and by the very fact of its own inherent absurdity, it is impossible. God has to submit to the logical law of contradiction, and He cannot, according to the theologians, cause two and two to make either more or less than four. Either the law of necessity is above Him or He Himself is the law of necessity. And in the moral order the question arises whether falsehood, or homicide, or adultery, are wrong because He has so decreed it, or whether He has so decreed it because they are wrong. If the former, then God is a capricious and unreasonable God, who decrees one law when He might equally well have decreed another, or, if the latter, He obeys an intrinsic nature and essence which exists in things themselves independently of Him—that is to say, independently of His sovereign will; and if this is the case, if He obeys the innate reason of things, this reason, if we could but know it, would suffice us without any further need of God, and since we do not know it, God explains nothing. This reason would be above God. Neither is it of any avail to say that this reason is God Himself, the supreme reason of things. A reason of this kind, a necessary reason, is not a personal something. It is will that gives personality. And it is because of this problem of the relations between God's reason, necessarily necessary, and His will, necessarily free, that the logical and Aristotelian God will always be a contradictory God.
