Famous quotes containing the words energy and/or demands:
“The scholar may be sure that he writes the tougher truth for the calluses on his palms. They give firmness to the sentence. Indeed, the mind never makes a great and successful effort, without a corresponding energy of the body.”
—Henry David Thoreau (1817–1862)
“When the doctrine of allegiance to party can utterly up-end a man’s moral constitution and make a temporary fool of him besides, what excuse are you going to offer for preaching it, teaching it, extending it, perpetuating it? Shall you say, the best good of the country demands allegiance to party? Shall you also say it demands that a man kick his truth and his conscience into the gutter, and become a mouthing lunatic, besides?”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
