Famous quotes containing the word power:
“No other human being, no woman, no poem or music, book or painting can replace alcohol in its power to give man the illusion of real creation.”
—Marguerite Duras (b. 1914)
“With all of my power of living
I am forced to lie on the floor.”
—John Ashbery (b. 1927)
“But the life of Spirit is not the life that shrinks from death and keeps itself untouched by devastation, but rather the life that endures it and maintains itself in it. It wins its truth only when, in utter dismemberment, it finds itself.... Spirit is this power only by looking the negative in the face, and tarrying with it. This tarrying with the negative is the magical power that converts it into being. This power is identical with what we earlier called the Subject.”
—Georg Wilhelm Friedrich Hegel (1770–1831)
