Man is such a conservative creature that any change, even a change for the better, scares him, he prefers the bad old way to the new good one. A man who has been all his life a confirmed materialist would not consent to believe that the soul was immortal, not if it were proved to him _more geometrico,_ and not if he were a constitutional coward, fearing death like Shakespeare's Falstaff. Then we must take human conceit into account. Men do not like to admit themselves wrong. It is absurd, but it is so. Men, trivial, wretched creatures, proved by history and by every common event to be bunglers, yet must needs consider themselves infallible, omniscient. What for? Why not admit their ignorance flatly and frankly? True, it is easier said than done. But why should slavish intellect, in spite of our desire to be straightforward, deck us out with would-be truths, of which we cannot divest ourselves even when we know their flimsiness. Socrates wanted to think that he knew nothing--but he could not bring it off. He most absorbedly believed in his own knowledge; nothing could be "truth," except his teaching; he accepted the decree of the oracle, and sincerely esteemed himself the wisest of men. And so it will be, as long as philosophers feel it their duty to teach and to save their neighbours. If a man wants to help people, he is bound to become a liar. We should undertake doubt seriously, not in order to return at length to established beliefs, for that would be a vicious circle. Experience shows us that such a process, certainly in the development of ultimate questions, only leads from error to error; we should doubt _so that doubt becomes a continuous creative force, inspiring the very essence of our life_. For established knowledge argues in us a condition of imperfect receptivity. The weak, flabby spirit cannot bear quick, ceaseless change. It must look round, it must have time to gather its wits, and so it must undergo the same experience time after time. It needs the support and the security of habit, But the well-grown soul despises your crutches. He is tired of crawling on his own cabbage patch, he tears himself away from his own "native" soil, and takes himself off into the far distances, braving the infinitude of space. Surely everybody knows we are not to live in the world for ever. But cowardice prevents one straightforward admitting of it, we keep it close till there is an occasion to air it as a truism. Only when misfortune, disease, old age come upon us, then the dread fear of departure walks with us like our own skeleton. We cannot dismiss him. At length, involuntarily, we begin to examine our gruesome companion with curiosity. And then, strangely enough, we observe that he not only tortures us, but, keeping pace with us, he has begun to gnaw through all the threads that bind us to the old existence. At moments it seems as if, a few more threads gone, nothing, nothing will remain to hold
