Famous quotes containing the word heart:
“For it is a fire that, kindling its first embers in the narrow nook of a private bosom, caught from a wandering spark out of another private heart, glows and enlarges until it warms and beams upon multitudes of men and women, upon the universal heart of all, and so lights up the whole world and all nature with its generous flames.”
—Ralph Waldo Emerson (1803–1882)
“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)
“A torn jacket is soon mended; but hard words bruise the heart of a child.”
—Henry Wadsworth Longfellow (20th century)
