Famous quotes containing the words physical force, physical and/or force:
“Physical force has no value, where there is nothing else. Snow in snow-banks, fire in volcanoes and solfataras is cheap. The luxury of ice is in tropical countries, and midsummer days. The luxury of fire is, to have a little on our hearth; and of electricity, not the volleys of the charged cloud, but the manageable stream on the battery-wires. So of spirit, or energy; the rests or remains of it in the civil and moral man, are worth all the cannibals in the Pacific.”
—Ralph Waldo Emerson (1803–1882)
“The real stumbling-block of totalitarian régimes is not the spiritual need of men for freedom of thought; it is men’s inability to stand the physical and nervous strain of a permanent state of excitement, except during a few years of their youth.”
—Simone Weil (1909–1943)
“The ideas of the ruling class are in every epoch the ruling ideas, i.e. the class which is the ruling material force of society, is at the same time its ruling intellectual force.”
—Karl Marx (1818–1883)
