Famous quotes containing the words terms, based and/or rates:
“Picture the prince, such as most of them are today: a man ignorant of the law, well-nigh an enemy to his people’s advantage, while intent on his personal convenience, a dedicated voluptuary, a hater of learning, freedom and truth, without a thought for the interests of his country, and measuring everything in terms of his own profit and desires.”
—Desiderius Erasmus (c. 1466–1536)
“Any reductionist program has to be based on an analysis of what is to be reduced. If the analysis leaves something out, the problem will be falsely posed.”
—Thomas Nagel (b. 1938)
“[The] elderly and timid single gentleman in Paris ... never drove down the Champs Elysees without expecting an accident, and commonly witnessing one; or found himself in the neighborhood of an official without calculating the chances of a bomb. So long as the rates of progress held good, these bombs would double in force and number every ten years.”
—Henry Brooks Adams (1838–1918)
