The Will to Power · Friedrich Wilhelm Nietzsche
578.
_Moral values in epistemology itself:_-- The faith in reason--why not mistrust? The "real world" is the good world--why? Appearance, change, contradiction, struggle, regarded as immoral: the desire for a world which _knows nothing_ of these things. The transcendental world discovered, _so that_ a place may be kept for "moral freedom" (as in Kant). Dialectics as the road to virtue (in Plato and Socrates: probably because sophistry was held to be the road to immorality). Time and space are ideal: consequently there is unity in the essence of things; consequently no sin, no evil, no imperfection, a _justification_ of God. Epicurus _denied_ the possibility of knowledge, in order to keep the moral (particularly the hedonistic) values as the highest. Augustine does the same, and later Pascal ("corrupted reason"), in favour of Christian values. Descartes' contempt for everything variable; likewise Spinoza's.
