No Altruism! Friedrich Nietzsche

I see in many men an excessive impulse and delight in wanting to be a function; they strive after it, and have the keenest scent for all those positions in which precisely they themselves can be functions. Among such persons are those women who transform themselves into just that function of a man that is but weakly developed in him, and then become his purse, or his politics, or his social intercourse. Such beings maintain themselves best when they insert themselves in an alien organism; if they do not succeed they become vexed, irritated, and eat themselves up.
