“When the situation is, what we would wish, nothing is so ill- timed as to hint at the circumstances which make it so: you thank Fortune ... you had reason—the heart knew it, and was satisfied; and who but an English philosopher would have sent notices of it to the brain to reverse the judgment?”
—Laurence Sterne (1713–1768)
“When we can drain the Ocean into mill-ponds, and bottle up the Force of Gravity, to be sold by retail, in gas jars; then may we hope to comprehend the infinitudes of man’s soul under formulas of Profit and Loss; and rule over this too, as over a patent engine, by checks, and valves, and balances.”
—Thomas Carlyle (1795–1881)
“If I were to be taken hostage, I would not plead for release nor would I want my government to be blackmailed. I think certain government officials, industrialists and celebrated persons should make it clear they are prepared to be sacrificed if taken hostage. If that were done, what gain would there be for terrorists in taking hostages?”
—Margaret Mead (1901–1978)
