MÜLLER Thomas – Entre liberté et nécessité : autour de deux débats au XIXème siècle

What do free will and mathematics have in common? One may consider that no serious link can be done between a language, mathematics, and a metaphysical doctrine, determinism.

Nevertheless, such a question became a prominent one in the xix century, and concerned economists, social scientists, mathematician and physicists.

The common ground of all those debates was a vision of determinism as a consequence of a mechanistic view of nature that was prominent between physicists and was imported into the human sciences through the use of statistic by Adolphe Quetelet.

Quetelet, an astronomer, considered statistical regularities as the expression of hidden social laws, and was forced to explain the compatibility of those laws with free will. His widespread influence on the human sciences may explain Léon Walras’s rejection of mathematical economics by Pierre Emile Levasseur.

In order to save freedom of the will, Quetelet had to deny any link between the macroscopic regularities of the averages and individual behaviour. Walras’s general equilibrium, with his stress on the individual agent was understood as a reestablishment of this same link and thus rejected by Levasseur.

At the same time, Quetelet exerted a major influence on Maxwel’s kinetic theory of gases. Inspired by Quetelet views on statistics, Maxwell developed a kinetic theory of gases that treated atoms in the same way that Quetelet considered individuals. Maxwell was also concerned with the question of the compatibility between the determinism of physical laws and free will. Inspired by Quetelet answer on the independence between individual behaviour and statistical regularities, he showed that there are no reasons to consider atoms as deterministic systems in view of the macroscopic regularities of gas laws.

Still lacking a convincing source of indeterminism for the atomic behaviour, he became aware of a strange mathematical results by Joseph Boussinesq. Boussinesq, a French mathematician, had found a class of differential equations with more than one solution. Those equations, that describe very special kind of unstable equilibria, were interpreted by Boussinesq as the final proof that Laplacian determinism was a mistake. The debate that followed Boussinesq mémoire mixed very different kind of arguments, some of them of a physical nature, some indebted with Quetelet, and others of a speculative, philosophical nature.

The historical roots that we have reconstructed explain this unusual entanglement of very heterogeneous perspectives, spreading over different disciplines such as statistics, physics, mathematics and the social sciences, and helps us in understanding what free will and mathematics had in common.


BRISSET Nicolas – Performativité des énoncés de la théorie économique: une approche conventionnaliste

The phenomenon of performativity has recently produced debates about the status of the economic discourse. This thesis aims to discuss the subjectivist idea that if economics “performs” (shapes) the social reality, rather than merely reflect it, then every theory can be “true”. My main goal is to point out the limits of performativity in three ways. First, no theory can be performative because some do not produce empirical landmarks for the agents. Second, the social institutions restrict the performativity. Third, I emphasize the necessity for a theory to be self-fulfilling. This thesis is a prelude to a new kind of performative studies based on an original definition: a theory performs the world if it implies a behavioral regularity which leads to the general coordination between agents. That is to say, if it becomes a convention à la David Lewis.

MISSEMER Antoine – L'analyse économique face à l'épuisement des ressources naturelles: de William Stanley Jevons à Harold Hotelling (1865-1931) - le cas des énergies fossiles

Fossil fuels exhaustion is a current topic. It is often said that its first presages appeared in the 1970s with the first oil shock. Actually, this exhaustion fear is much older than that, it started with the Industrial Revolution and kept going since then. In the second part of the 19th century, some economists focused their attention on the mineral resources depletion, which was at the time an ‘unknown item’ that necessitated the creation of new concepts and new analytical tools to deal with (for example Jevons’ rebound-effect, Marshall-Einaudi’s mining rent). In the 1910s and 1920s, thanks to technical progress and the development of new energies (oil, hydro-electricity), their fears about industrial decline progressively dissipated. Yet, these factual evolutions are not the only ones to consider. Internal factors, inside economic science (marginalism in the 1870s, capital theory in the 1890s), also shaped economists’ viewpoint on resources exhaustion. Why? How? What lessons can we get from this period for our current environmental challenges? These are the questions that are studied in this thesis.

Keywords: history of environmental and natural resources economics, Jevons, peak oil, history of economic thought, Hotelling.
