Abstract
“Let us apply to the political and moral sciences the method founded upon observation and upon calculus, the method which has served us so well in the natural sciences.” The social sciences have known no truer follower of Laplace's dictum than Adolphe Quetelet. Hismécanique sociale, laterphysique sociale, was conceived as the social analogue to Laplace'smecanique celeste, and embodied the results of an unswerving commitment not only to the presumed method of celestial physics, but even to its concepts and vocabulary. It is too weak to say that Quetelet's goal was the transmission of the achievements of celestial physics into the social sphere. He aspired to nothing less than imitation.
