Famous quotes containing the word practical:
“One of the great triumphs of the nineteenth century was to limit the connotation of the word “immoral” in such a way that, for practical purposes, only those were immoral who drank too much or made too copious love. Those who indulged in any or all of the other deadly sins could look down in righteous indignation on the lascivious and the gluttonous.... In the name of all lechers and boozers I most solemnly protest against the invidious distinction made to our prejudice.”
—Aldous Huxley (1894–1963)
“I do not remember anything which Confucius has said directly respecting man’s “origin, purpose, and destiny.” He was more practical than that. He is full of wisdom applied to human relations,—to the private life,—the family,—government, etc. It is remarkable that, according to his own account, the sum and substance of his teaching is, as you know, to do as you would be done by.”
—Henry David Thoreau (1817–1862)
