Famous quotes containing the word heart:
“My heart is as some famine-murdered land
Whence all good things have perished utterly,
And well I know my soul in Hell must lie
If I this night before God’s throne should stand.”
—Oscar Wilde (1854–1900)
“I’m beginning to believe that Killer Illiteracy ought to rank near heart disease and cancer as one of the leading causes of death among Americans. What you don’t know can indeed hurt you, and so those who can neither read nor write lead miserable lives, like Richard Wright’s character, Bigger Thomas, born dead with no past or future.”
—Ishmael Reed (b. 1938)
“Poor shad! where is thy redress? When Nature gave thee instinct, gave she thee the heart to bear thy fate? Still wandering the sea in thy scaly armor to inquire humbly at the mouths of rivers if man has perchance left them free for thee to enter.”
—Henry David Thoreau (1817–1862)
