Adolphe Quetelet Quotes (1796-1874)

“The more advanced the sciences have become, the more they have tended to enter the domain of mathematics, which is a sort of center towards which they converge. We can judge of the perfection to which a science has come by the facility, more or less great, with which it may be approached by calculation.”

“The more advanced the sciences have become, the more they have tended to enter the domain of mathematics, which is a sort of center towards which they converge. We can judge of the perfection to which a science has come by the facility, more or less great, with which it may be approached by calculation.”

“The influence of Quetelet's ideas spread throughout the sciences, even to the physical sciences. The two primary founders of the modern kinetic theory of gases, based on considerations of probability, were James Clerk Maxwell and Ludwig Boltzmann. Both acknowledged their debt to Quetelet. ...historians generally consider the influence of the natural sciences on the social sciences, whereas in the case of Maxwell and Boltzmann, there is an influence of the social sciences on the natural sciences, as Theodore Porter has shown.”

“God had been forcefully excluded from astronomy during the French Revolution, when Pierre-Simon Laplace rewrote Newton's ideas to create his [Laplace's] deterministic cosmos, in which scientific laws govern every movement of every planet with no need for divine intervention. Inspired by his success, a Belgian astronomer called Alphonse Quetelet decided that human societies are also controlled by laws. ...and so Quetelet suggested that an 'average man' can consistently encapsulate a nation's characteristics. ...Quetelet's successors took his ideas in many different directions. ...Data collection projects proliferated, and statisticians searched for laws governing every aspect of life. ...In physics, the most important application of statistics was to gases.”

“The most important of Quetelet's statistical principles... include the conception of the Average Man as a type, the significance for social science of the regularities found in the moral actions of man, and the theoretical basis of the distribution of group phenomena about their type.”

“Quetelet published quite a number of poems, and until the age of thirty he continued to exercise his poetical talents as pastime and relief from his scientific studies. His poems were of a serious tone, but were well received by both public and critics. We may mention here an Essai sur la romance, which Quetelet brought out in 1823. ...This essay, together with translations, in prose and in verse, of German, English, Italian, and Spanish romances, shows Quetelet's wide acquaintance at that early age with the various European literatures.”

“The mere enumeration of his contributions to pure and mixed mathematics would occupy a very large space, and from their intrinsic merit, patient and conscientious research and earnest regard for truth, would alone have secured him a foremost place among the distinguished and scientific men of the present century.”

“In principle, wrote Quetelet, the courage or criminality of a real person could be established... but it was wholly unnecessary for social physics. Instead, the physicist need only arrange that courageous and criminal acts be recorded throughout society, as the latter already were, and then the average man could be assigned a "penchant for crime" equal to the number of criminal acts committed divided by the population. In this way, a set of discrete acts by distinct individuals was transformed into a continuous magnitude... an attribute of the average man.”

“Maxwell... mastered electricity and magnetism, light and heat, pretty much mopping up all the major areas of physics beyond those that Newton had... taken care of—gravitation and the laws of motion. ...Maxwell detected an essential shortcoming in Newton's laws of motion, too. They worked... for macroscopic objects, like cannonballs and rocks. But what about the submicroscopic molecules from which such objects were made? ...Newton's laws ...did you no good because you could not possibly trace the motion of an individual molecule ...Maxwell applied the sort of statistical thinking that Quetelet had promoted.”

“No other work in the English language contains such an extensive and succinct account of the different branches of physics or exhibits such a general knowledge of the whole field in so small a compass.”
