Of this kind of moral stuff civilized society is composed. The atmosphere is charged with it; we breathe it with every breath and drink it with our mother’s milk. Culture and education refine these things slightly but leave them basically untouched. A whole world of literature has been created to justify this kind of life as the only normal one. And this is the more to be wondered at seeing that these are the evils which make life the bitter struggle it is for all of us. All our heartaches and a great many of our physical ills spring directly out of our sins. Pride, arrogance, resentfulness, evil imaginings, malice, greed: these are the sources of more human pain than all the diseases that ever afflicted mortal flesh.
