The idea of sensational existence is indeed already involved in the characteristic expression “external to us.” It is true that a sophistical theology refuses to interpret the word “external” in its proper, natural sense, and substitutes the indefinite expression of independent, separate existence. But if the externality is only figurative, the existence also is figurative. And yet we are here only concerned with existence in the proper sense, and external existence is alone the definite, real, unshrinking expression for separate existence.
Real, sensational existence is that which is not dependent on my own mental spontaneity or activity, but by which I am involuntarily affected, which is when I am not, when I do not think of it or feel it. The existence of God must therefore be in space—in general, a qualitative, sensational existence. But God is not seen, not heard, not perceived by the senses. He does not exist for me, if I do not exist for him; if I do not believe in a God, there is no God for me. If I am not devoutly disposed, if I do not raise myself above the life of the senses, he has no place in my consciousness. Thus he exists only in so far as he is felt, thought, believed in;—the addition “for me” is unnecessary. His existence therefore is a real one, yet at the same time not a real one;—a spiritual existence, says the theologian. But spiritual existence is only an existence in thought, in feeling, in belief; so that his existence is a medium between sensational existence and conceptional existence, a medium full of contradiction. Or: he is a sensational existence, to which however all the conditions of sensational existence are wanting:—consequently an existence at once sensational and not sensational, an existence which contradicts the idea of the sensational, or only a vague existence in general, which is fundamentally a sensational one, but which, in order that this may not become evident, is divested of all the predicates of a real, sensational existence. But such an “existence in general” is self-contradictory. To existence belongs full, definite reality.
A necessary consequence of this contradiction is Atheism. The existence of God is essentially an empirical existence, without having its distinctive marks; it is in itself a matter of experience, and yet in reality no object of experience. It calls upon man to seek it in Reality: it impregnates his mind with sensational conceptions and pretensions; hence, when these are not fulfilled—when, on the contrary, he finds experience in contradiction with these conceptions, he is perfectly justified in denying that existence.
Kant is well known to have maintained, in his critique of the proofs of the existence of God, that that existence is not susceptible of proof from reason. He did not merit, on this account, the blame which was cast on him by Hegel. The idea of the existence of God in those proofs is a thoroughly empirical one; but I cannot deduce empirical existence from an à priori idea. The only real ground of blame against Kant is, that in laying down this position he supposed it to be something remarkable, whereas it is self-evident. Reason cannot constitute itself an object of sense. I cannot, in thinking, at the same time represent what I think as a sensible object, external to me. The proof of the existence of God transcends the limits of the reason; true; but in the same sense in which sight, hearing, smelling transcend the limits of the reason. It is absurd to reproach reason that it does not satisfy a demand which can only address itself to the senses. Existence, empirical existence, is proved to me by the senses alone; and in the question as to the being of God, the existence implied has not the significance of inward reality, of truth, but the significance of a formal, external existence. Hence there is perfect truth in the allegation that the belief that God is or is not has no consequence with respect to inward moral dispositions. It is true that the thought: There is a God, is inspiring; but here the is means inward reality; here the existence is a movement of inspiration, an act of aspiration. Just in proportion as this existence becomes a prosaic, an empirical truth, the inspiration is extinguished.
Religion, therefore, in so far as it is founded on the existence of God as an empirical truth, is a matter of indifference to the inward disposition. As, necessarily, in the religious cultus, ceremonies, observances, sacraments, apart from the moral spirit or disposition, become in themselves an important fact: so also, at last, belief in the existence of God becomes, apart from the inherent quality, the spiritual import of the idea of God, a chief point in religion. If thou only believest in God—believest that God is, thou art already saved. Whether under this God thou conceivest a really divine being or a monster, a Nero or a Caligula, an image of thy passions, thy revenge, or ambition, it is all one,—the main point is that thou be not an atheist. The history of religion has amply confirmed this consequence which we here draw from the idea of the divine existence. If the existence of God, taken by itself, had not rooted itself as a religious truth in minds, there would never have been those infamous, senseless, horrible ideas of God which stigmatise the history of religion and theology. The existence of God was a common, external, and yet at the same time a holy thing:—what wonder, then, if on this ground the commonest, rudest, most unholy conceptions and opinions sprang up!
Atheism was supposed, and is even now supposed, to be the negation of all moral principle, of all moral foundations and bonds: if God is not, all distinction between good and bad, virtue and vice, is abolished. Thus the distinction lies only in the existence of God; the reality of virtue lies not in itself, but out of it. And assuredly it is not from an attachment to virtue, from a conviction of its intrinsic worth and importance, that the reality of it is thus bound up with the existence of God. On the contrary, the belief that God is the necessary condition of virtue is the belief in the nothingness of virtue in itself.
It is indeed worthy of remark that the idea of the empirical existence of God has been perfectly developed in modern times, in which empiricism and materialism in general have arrived at their full blow. It is true that even in the original, simple religious mind, God is an empirical existence to be found in a place, though above the earth. But here this conception has not so naked, so prosaic a significance; the imagination identifies again the external God with the soul of man. The imagination is, in general, the true place of an existence which is absent, not present to the senses, though nevertheless sensational in its essence.[2] Only the imagination solves the contradiction in an existence which is at once sensational and not sensational; only the imagination is the preservative from atheism. In the imagination existence has sensational effects,—existence affirms itself as a power; with the essence of sensational existence the imagination associates also the phenomena of sensational existence. Where the existence of God is a living truth, an object on which the imagination exercises itself, there also appearances of God are believed in.[3] Where, on the contrary, the fire of the religious imagination is extinct, where the sensational effects or appearances necessarily connected with an essentially sensational existence cease, there the existence becomes a dead, self-contradictory existence, which falls irrecoverably into the negation of atheism.
The belief in the existence of God is the belief in a special existence, separate from the existence of man and Nature. A special existence can only be proved in a special manner. This faith is therefore only then a true and living one when special effects, immediate appearances of God, miracles, are believed in. Where, on the other hand, the belief in God is identified with the belief in the world, where the belief in God is no longer a special faith, where the general being of the world takes possession of the whole man, there also vanishes the belief in special effects and appearances of God. Belief in God is wrecked, is stranded on the belief in the world, in natural effects as the only true ones. As here the belief in miracles is no longer anything more than the belief in historical, past miracles, so the existence of God is also only an historical, in itself atheistic conception.
[1] At the same time, however, their result is to prove the nature of man. The various proofs of the existence of God are nothing else than various highly interesting forms in which the human nature affirms itself. Thus, for example, the physico-theological proof (or proof from design) is the self-affirmation of the calculated activity of the understanding. Every philosophic system is, in this sense, a proof of the existence of God. [↑]
