Famous quotes containing the words impulse and/or technique:
“Whereas the Greeks gave to will the boundaries of reason, we have come to put the will’s impulse in the very center of reason, which has, as a result, become deadly.”
—Albert Camus (1913–1960)
“The audience is the most revered member of the theater. Without an audience there is no theater. Every technique learned by the actor, every curtain, every flat on the stage, every careful analysis by the director, every coordinated scene, is for the enjoyment of the audience. They are our guests, our evaluators, and the last spoke in the wheel which can then begin to roll. They make the performance meaningful.”
—Viola Spolin (b. 1911)
