Famous quotes containing the words reaction and/or wheel:
“An actor must communicate his author’s given message—comedy, tragedy, serio- comedy; then comes his unique moment, as he is confronted by the looked-for, yet at times unexpected, reaction of the audience. This split second is his; he is in command of his medium; the effect vanishes into thin air; but that moment has a power all its own and, like power in any form, is stimulating and alluring.”
—Eleanor Robson Belmont (1878–1979)
“The wheel and the brake have different duties, but also one in common: to hurt one another.”
—Friedrich Nietzsche (1844–1900)
