According to the conventions of the genre, Augustus Waters kept his sense of humor till the end, did not for a moment waiver in his courage, and his spirit soared like an indomitable eagle until the world itself could not contain his joyous soul.

A child said, What is the grass? Fetching it to me will full hands; How could I answer the child?...... I do not know what it is any more than he. I guess it must be the flag of my disposition, out of hopeful green stuff woven. There was the hope Dr. Holden had talked about-the grass was a metaphor for his hope. But that’s not all. He continues, Or I guess it is the handkerchief of the Lord, A scented gift and remembrance resignedly dropped, Like grass is a metaphor for God's greatness or something.... And then soon after is itself a child.... And then soon after that, Or, I guess it is a uniform hieroglyphic, And it means, Sprouting alike in broad zones and narrow zones. Growing among black folk as among white.

All along — not only since she left, but for a decade before — I had been imagining her without listening, without knowing that she made as a poor a window as I did. And so I could not imagine her as a person who could feel fear, who could feel isolated in a roomful of people, who could be shy about her record collection because it was too personal to share. Someone who might have read travel books to escape having to live in the town that so many people escape to. Someone who — because no one thought she was a person — had no one to really talk to.

All I know of heaven and all I know of death is in this park: an elegant universe in ceaseless motion, teeming with ruined ruins and screaming children.

All of us, poor & rich alike, have been conditioned by our upbringings. Impoverished men & women may become lulled into a state of "learned helplessness" without hope to change their lives. Likewise, the wealthy can walk in a state of "learned blindness" ignoring the desperation of the local & global poor.

All right. The snow may be falling in the winter of my discontent, but at least I've got sarcastic company.

All salvation is temporary, . . I bought them a minute. Maybe that's the minute that buys them an hour, which is the hour that buys them a year. No one's going to buy them forever, Hazel Grace, but my life bought them a minute. And that's not nothing.
