Famous quotes containing the word extent:
“To the extent to which genius can be conjoined with a merely good human being, Haydn possessed genius. He never exceeds the limits that morality sets for the intellect; he only composes music which has “no past.””
—Friedrich Nietzsche (1844–1900)
“I expect a time when, or rather an integrity by which, a man will get his coat as honestly and as perfectly fitting as a tree its bark. Now our garments are typical of our conformity to the ways of the world, i.e., of the devil, and to some extent react on us and poison us, like that shirt which Hercules put on.”
—Henry David Thoreau (1817–1862)
“We respond to a drama to that extent to which it corresponds to our dreamlife.”
—David Mamet (b. 1947)
