Thus Spake Zarathustra: A Book for All and None by Friedrich Wilhelm Nietzsche

Here we have a description of that courageous and wayward spirit that literally haunts the footsteps of every great thinker and every great leader; sometimes with the result that it loses all aims, all hopes, and all trust in a definite goal. It is the case of the bravest and most broad-minded men of to-day. These literally shadow the most daring movements in the science and art of their generation; they completely lose their bearings and actually find themselves, in the end, without a way, a goal, or a home. “On every surface have I already sat!...I become thin, I am almost equal to a shadow!” At last, in despair, such men do indeed cry out: “Nothing is true; all is permitted,” and then they become mere wreckage. “Too much hath become clear unto me: now nothing mattereth to me any more. Nothing liveth any longer that I love,—how should I still love myself! Have I still a goal? Where is MY home?” Zarathustra realises the danger threatening such a man. “Thy danger is not small, thou free spirit and wanderer,” he says. “Thou hast had a bad day. See that a still worse evening doth not overtake thee!” The danger Zarathustra refers to is precisely this, that even a prison may seem a blessing to such a man. At least the bars keep him in a place of rest; a place of confinement, at its worst, is real. “Beware lest in the end a narrow faith capture thee,” says Zarathustra, “for now everything that is narrow and fixed seduceth and tempteth thee.”
