Context

“A Criticism of the Morality of Decadence.—An "altruistic" morality, a morality under which selfishness withers, is in all circumstances a bad sign. This is true of individuals and above all of nations. The best are lacking when selfishness begins to be lacking. Instinctively to select that which is harmful to one, to be lured by "disinterested" motives,—these things almost provide the formula for decadence. "Not to have one's own interests at heart" —this is simply a moral fig-leaf concealing a very different fact, a physiological one, to wit:—"I no longer know how to find what is to my interest."...” source
