“The compulsion to do good is an innate American trait. Only North Americans seem to believe that they always should, may, and actually can choose somebody with whom to share their blessings. Ultimately this attitude leads to bombing people into the acceptance of gifts.”
—Ivan Illich (b. 1926)
“When the Somalians were merely another hungry third world people, we sent them guns. Now that they are falling down dead from starvation, we send them troops. Some may see in this a tidy metaphor for the entire relationship between north and south. But it would make a whole lot more sense nutritionally—as well as providing infinitely more vivid viewing—if the Somalians could be persuaded to eat the troops.”
—Barbara Ehrenreich (b. 1941)
“Even American women are not felt to be persons in the same sense as the male immigrants among the Hungarians, Poles, Russian Jews,—not to speak of Italians, Germans, and the masters of all of us—the Irish!”
—Mary Putnam Jacobi (1842–1906)
“Constant revolutionizing of production ... distinguish the bourgeois epoch from all earlier ones. All fixed, fast-frozen relations, with their train of ancient and venerable prejudices are swept away, all new-formed ones become antiquated before they can ossify. All that is solid melts into air, all that is holy is profaned, and man is at last compelled to face with sober senses, his real conditions of life, and his relations with his kind.”
—Karl Marx (1818–1883)
“He took control of me for forty-five minutes. This time I’ll have control over him for the rest of his life. If he gets out fifteen years from now, I’ll know. I’ll check on him every three months through police computers. If he makes one mistake he’s going down again. I’ll make sure. I’m his worst enemy now.”
—Elizabeth Wilson, U.S. crime victim. As quoted in People magazine, p. 88 (May 31, 1993)
“The only people who treasure systems are those whom the whole truth evades, who want to catch it by the tail. A system is just like truth’s tail, but the truth is like a lizard. It will leave the tail in your hand and escape; it knows that it will soon grow another tail.”
—Ivan Sergeevich Turgenev (1818–1883)
