Faith is always coveted most and needed most urgently where will is lacking; for will, as the affect of command, is the decisive sign of sovereignty and strength. In other words, the less one knows how to command, the more urgently one covets someone who commands, who commands severely—a god, prince, class, physician, father confessor, dogma, or party conscience. From this one might perhaps gather that the two world religions, Buddhism and Christianity, may have owed their origin and above all their sudden spread to a tremendous collapse and disease of the will. And that is what actually happened: both religions encountered a situation in which the will had become diseased, giving rise to a demand that had become utterly desperate for some "thou shalt." Both religions taught fanaticism in ages in which the will had become exhausted, and thus they offered innumerable people some support, a new possibility of willing, some delight in willing. For fanaticism is the only "strength of the will" that even the weak and insecure can be brought to attain, being a sort of hypnotism of the whole system of the senses and the intellect for the benefit of an excessive nourishment (hypertrophy) of a single point of view and feeling that henceforth becomes dominant— which the Christian calls his faith. Once a human being reaches the fundamental conviction that he must be commanded, he becomes "a believer."Conversely, one could conceive of such a pleasure and power of self-determination, such a freedom of the will [ This conception of "freedom of the will" ( alias, autonomy) does not involve any belief in what Nietzsche called "the superstition of free will" in section 345 ( alias, the exemption of human actions from an otherwise universal determinism).] that the spirit would take leave of all faith and every wish for certainty, being practiced in maintaining himself on insubstantial ropes and possibilities and dancing even near abysses. Such a spirit would be the free spirit par excellence.
