Preach, my dear Sir, a crusade against ignorance; establish and improve the law for educating the common people. Let our countrymen know that the people alone can protect us against these evils, and that the tax which will be paid for this purpose is not more than the thousandth part of what will be paid to kings, priests and nobles who will rise up among us if we leave the people in ignorance.
“The crucial event was that one which for almost two hundred years had been felt to be impossible, but which nevertheless took place near the start of this century: the fall of the Newtonian empire in physics. This catastrophe, and the period of extreme turbulence in physics which it inaugurated, changed the entire history of the philosophy of science. Almost all philosophers of the 18th and 19th centuries, it was now clear, had enormously exaggerated the certainty and extent of scientific knowledge.” ~David Stove, “Popper and After”
