Famous quotes containing the word action:
“Each action of the actor on the stage should be the visible concomitant of his thoughts.”
—Sarah Bernhardt (1845–1923)
“Besides, our action on each other, good as well as evil, is so incidental and at random, that we can seldom hear the acknowledgments of any person who would thank us for a benefit, without some shame and humiliation. We can rarely strike a direct stroke, but must be content with an oblique one; we seldom have the satisfaction of yielding a direct benefit, which is directly received.”
—Ralph Waldo Emerson (1803–1882)
“Man must vanquish himself, must do himself violence, in order to perform the slightest action untainted by evil.”
—E.M. Cioran (b. 1911)
