“We are to regard existence as a raid or great adventure; it is to be judged, therefore, not by what calamities it encounters, but by what flag it follows and what high town it assaults. The most dangerous thing in the world is to be alive; one is always in danger of one's life. But anyone who shrinks from that is a traitor to the great scheme and experiment of being.”

“If we were to one day encounter a form of life more powerful and intelligent than our own, and it regarded us as we regard fish, what would be our argument against being eaten?”

“One great question underlies our experience, whether we think about it or not: what is the purpose of life? . . . From the moment of birth every human being wants happiness and does not want suffering. Neither social conditioning nor education nor ideology affects this. From the very core of our being, we simply desire contentment. . . Therefore, it is important to discover what will bring about the greatest degree of happiness.”

“What people regard as vanity—leaving great works, having children, acting in such a way as to prevent one's name from being forgotten—I regard as the highest expression of human dignity.”

“The great thing, if one can, is to stop regarding all the unpleasant things as interruptions of one's 'own,' or 'real' life. The truth is of course that what one calls the interruptions are precisely one's real life -- the life God is sending one day by day.”

“It is a great danger for everyone when what is shocking changes.”
