No one who is willing to confess the truth can deny that in every human soul, even in one already resolutely set toward faith in transcendental things, serious doubts can now and then arise as to the reality of all its conceptions and hopes. They who most vehemently condemn such temporary doubts in others are not the ones who are the best confirmed in the faith, for by such zeal they are often only seeking forcibly to suppress their own doubts. But in such moments, thus much remains sure, that there is no certainty anywhere to be found as to the great questions of the present and future life, better than that which Christianity affords, and that there is no adequate satisfaction to be found in trying to content oneself with only the results of “natural science,” many of which are still very uncertain; while one simply banishes from his thoughts all further questions, as to the interrelation of all things in a higher sense, and as to the moral laws of the universe,--questions on which the life and welfare of humanity most of all depend. That will never succeed for long; after every such period of a bare realism which limits itself to a smaller aim, in all men not wholly superficial, not wholly submerged in the world of sense, there arises with irresistible power the impulse to investigate anew whether and how far the high pretension of Christianity to be the real, the unique truth, and the only truth that brings happiness, is a just pretension. This impulse you also will more or less experience; otherwise you would not have taken in your hand this book, which had its origin in that same impulse. In no case thrust the impulse back from the threshold; for it springs from the better part of your nature. Accept, rather, one more bit of counsel: First consider more closely the “prolegomena” of Christianity--those preliminary truths which it considers to be self-evident; its dogmas take account of only afterward, when you have already been able to resolve to live up to these preliminary truths with all the power you have. The reverse way is, to be sure, the more usual one, and it is the one to which we are wont to be directed in our schools and churches. But if this more usual course is taken, now and then there lies “a lion in the way” which does not appear upon the path proposed in this chapter. The power of resolve, of course, you will always be obliged to have, for only “he who overcometh shall inherit all things;” for the irresolute, as well as for those completely without faith, even in the most favorable case only the decay of their personal life stands in near and certain prospect.
