Bernard Shaw,
Man and Superman: A Comedy and a Philosophy
“ TANNER. That is the profoundest of mistakes, Tavy. It is the self-sacrificing women that sacrifice others most recklessly. Because they are unselfish, they are kind in little things. Because they have a purpose which is not their own purpose, but that of the whole universe, a man is nothing to them but an instrument of that purpose. OCTAVIUS. Don't be ungenerous, Jack. They take the tenderest care of us. TANNER. Yes, as a soldier takes care of his rifle or a musician of his violin. But do they allow us any purpose or freedom of our own? Will they lend us to one another? ”
