Famous quotes containing the word heart:
“The proper office of religion is to regulate the heart of men, humanize their conduct, infuse the spirit of temperance, order, and obedience; and as its operation is silent, and only enforces the motives of morality and justice, it is in danger of being overlooked, and confounded with these other motives.”
—David Hume (1711–1776)
“It is night,
And it is vanity, and age
Blackens the heart of Adam. Fear,
The yellow chirper, beaks its cage.”

“My heart pumps yet the poison draught of you.”
—William Empson (1906–1984)
