Saul Bellow said this quote

Unexpected intrusions of beauty. This is what life is.

~ Saul Bellow

The old continued to have one resurgence of foolishness after another, until the organism gave out altogether.

~ Saul Bellow

With one long breath, caught and held in his chest, he fought his sadness over his solitary life. Don't cry, you idiot! Live or die, but don't poison everything...

~ Saul Bellow

I see that I've become a really bad correspondent. It's not that I don't think of you. You come into my thoughts often. But when you do it appears to me that I owe you a particularly grand letter. And so you end in the warehouse of good intentions: Can't do it now. Then put it on hold. This is one's strategy for coping with old age, and with death--because one can't die with so many obligations in storage. Our clever species, so fertile and resourceful in denying its weaknesses.

~ Saul Bellow
