A few of literature’s memorable and thought provoking sentences

Starting with the most immortal line:

It was a dark and stormy night; the rain fell in torrents, except at occasional intervals, when it was checked by a violent gust of wind which swept up the streets (for it is in London that our scene lies), rattling along the house-tops, and fiercely agitating the scanty flame of the lamps that struggled against the darkness.

Edward Bulwer-Lytton, Paul Clifford (1830)

“I took a deep breath and listened to the old brag of my heart;
I am, I am, I am.”

Sylvia Plath, The Bell Jar (1963)

“It does not do well to dwell on dreams and forget to live,
remember that.”

J.K. Rowling, Harry Potter and the Sorcerer’s Stone (1999)
