Famous quotes containing the words roll and/or angle:
“It was easy to recognize in him the anti-social animus of a born evangelist, but there was also something else—a kind of voluptuous delight in the shabby and preposterous, a perverted aestheticism like that of a latter-day movie or radio fan, a wild will to roll in and snuffle balderdash as a cat rolls in and snuffles catnip.”
—H.L. (Henry Lewis)
“I fly in dreams, I know it is my privilege, I do not recall a single situation in dreams when I was unable to fly. To execute every sort of curve and angle with a light impulse, a flying mathematics—that is so distinct a happiness that it has permanently suffused my basic sense of happiness.”
—Friedrich Nietzsche (1844–1900)
