“Quetelet had introduced a radically new way of thinking about human beings. As one of his admirers put it, 'Man is seen to be an enigma only as an individual, in mass, he is a mathematical problem.' Quetelet's successors took his ideas in many different directions. For one thing, his work was valuable politically because it could be interpreted in different ways. While conservatives insisted that little could be done to alter the current system, radicals accused governments of impeding the natural course of progress, and Utopians--such as Karl Marx--envisaged harmonious societies governed by nature's own laws guaranteeing improvement. Data collection projects proliferated, and statisticians searched for laws governing every aspect of life, ranging from the weather to the growth of civilization, from stock market fluctuations to the incidence of disease. Many scientists took their ideas from Quetelet rather than from abstract textbooks--but they added their own twist. Whereas Quetelet regarded individual deviations from the norm as errors to be eliminated, scientists set out to study how variations occur.” Science Book:Science: A Four Thousand Year History Source: Science: A Four Thousand Year History
