I am quite well aware that this does not “explain” the feeling of duty and sin; besides, it is a matter of indifference to man’s welfare how this feeling is to be explained, whether as a superstition handed down for many generations, or as a belief wholly in accord with reason. Even if it be a superstition, the champion has not yet been found who is able to set humanity free from a nightmare which has burdened it from the beginning of time; the isolated, weak attempts to do so have for the most part fallen out very unhappily for those who undertook them. A man who, with clear, unclouded brow, openly denies duty and sin, and, though boldly believing he may do anything he pleases, has yet gone through his whole life glad-heartedly, with the certainty of his inner conviction unruffled--such a man we should first like to see, before we believe in him. And though such a man were to be found, he would stand alone and would be incomprehensible to all other men, so differently constituted. Duty and sin become wholly intelligible only when we recognize a personal, extra-mundane God from whose will this inner law proceeds; while the so-called “immanence” of God is but another name for atheism or pantheism. To be sure, it would be idle to desire a reasoned explanation of the transcendental God; everything transcendental by its very nature escapes our comprehension, and for this reason the so-called “proofs” of the existence of God have no power to convince the human understanding. Nor do they seem as yet ever to have convinced any one who did not first want to be. In so far, therefore, atheism has a certain right to declare itself not convinced; but it is itself just as little in a position to prove that its own system is in any way reasonable, or to solve the doubts which that system generates. Therefore so long as humanity abides, the matter will perhaps stand simply at this, that one can not prove there is a God, but just as little, if God indeed exists, can one remove him out of the account of his own life by a mere denial. The decisive question of all questions for every man (but always a question) will be: whether he shall attempt such a denial and be able to attain the inward peace he expects therefrom, or whether he shall acknowledge as binding the categorical demand of the oldest divine revelation, “I am the Lord thy God, and thou shalt have no other gods before me.”
