In this paper I explore a positivist methodological tradition in early demand theory, as exemplified by several common traits that I draw from the works of V. Pareto, H. L. Moore and H. Schultz. Assuming a current approach to explanation in the social sciences, I will discuss the building of their various explanans, showing that the three authors agreed on two distinctive methodological features: the exclusion of any causal commitment to psychology when explaining individual choice and the mandate to test the truth of demand theory on aggregate data by statistical means. However, I also contend, from an epistemological point of view, that the truth of demand theory was conceived of in three different ways by our authors. Inspired by Poincaré, Pareto assumed that many different theories could account for the same data on individual choice, coming close to a kind of conventionalism -though I prefer to refer to this position as theoreticism. Moore was himself akin to Pearson's approach, which could be named descriptivist insofar as it resolved scientific laws into statistical descriptions of the data. Finally, Schultz tried to reconcile both approaches in an adequationist stance with no success, as we shall see.

In this paper I offer an account of the normative dimension implicit in D. Bernoulli’s expected utility functions by means of an analysis of the juridical metaphors upon which the concept of mathematical expectation was moulded. Following a suggestion by the late E. Coumet, I show how this concept incorporated a certain standard of justice which was put in question by the St. Petersburg paradox. I contend that Bernoulli would have solved it by introducing an alternative normative criterion rather than a positive model of decision making processes

A la vista del catálogo de nuestro Instituto Nacional de Estadística, quién dejará de sorprenderse al descubrir entre las colecciones auspiciadas por el INED francés una dedicada a los Clásicos de la economía y la población, con cuidadísimas ediciones de Condorcet, Süssmilch, Quesnay, Graunt... A esta colección se suma ahora, bajo la dirección de Eric Brian, otra serie de Estudios e investigaciones históricas, cuyo primer volumen comentamos aquí. Matemáticas y acción política, compilado por Thierry Martin, es, además, una excelente representación de los trabajos que en Francia se desarrollan en torno a la matemática social desde múltiples enfoques.
