“The man who backbites an absent friend, nay, who does not stand up for him when another blames him, the man who angles for bursts of laughter and for the repute of a wit, who can invent what he never saw, who cannot keep a secret -- that man is black at heart: mark and avoid him.”

“He was a friendly but sad figure. People said of him: 'A rich man who is not proud. A fortunate man who does not look happy.”

“Lucky is the man who does not secretly believe that every possibility is open to him.”

“There are people, moreover, for whom even the absence of God is absent, who are shaken not by the privation of providence but by the privation of the privation, who live in a completely ungoverned and unconsoling world. To use the terms of another religious existentialist of Judaism against him: there is a man who is lonelier than the lonely man of faith, and he is the lonely man of no faith.”

“It is a good man who stands up for his friends, but an honorable man who stands up for his enemies.”

“Anyone who does not love Him Who made man has not learned to love man aright.”
