Famous quotes containing the word practical:
“Despair, feeding, as it always does, on phantasmagoria, is imperturbably leading literature to the rejection, en masse, of all divine and social laws, towards practical and theoretical evil.”
—Isidore Ducasse, Comte de Lautréamont (1846–1870)
“Tried by a New England eye, or the more practical wisdom of modern times, they are the oracles of a race already in its dotage; but held up to the sky, which is the only impartial and incorruptible ordeal, they are of a piece with its depth and serenity, and I am assured that they will have a place and significance as long as there is a sky to test them by.”
—Henry David Thoreau (1817–1862)
