There is nothing to make one indignant in the mere fact that life is hard, that men should toil and suffer pain. The planetary conditions once for all are such, and we can stand it. But that so many men, by mere accidents of birth and opportunity, should have a life of nothing else but toil and pain and hardness and inferiority imposed upon them, should have no vacation, while others natively no more deserving never get any taste of this campaigning life at all, — this is capable of arousing indignation in reflective minds. It may end by seeming shameful to all of us that some of us have nothing but campaigning, and others nothing but unmanly ease.
William James (1842-1910) American psychologist and philosopher
“The Moral Equivalent of War” (1906)
