Mankind is susceptible and suggestible in opposite directions, and the rivalry of influences is unsleeping.

Context

“The woman loves the man the more admiringly the stormier he shows himself, and the world deifies its rulers the more for being willful and unaccountable. But the woman in turn subjugates the man by the mystery of gentleness in beauty, and the saint has always charmed the world by something similar. Mankind is susceptible and suggestible in opposite directions, and the rivalry of influences is unsleeping. The saintly and the worldly ideal pursue their feud in literature as much as in real life. For Nietzsche the saint represents little but sneakingness and slavishness. He is the sophisticated invalid, the degenerate par excellence, the man of insufficient vitality.” source
