Gabriel Tarde’s book on economics is the last one he published. It has been totally forgotten even though it is a masterpiece of social psychology. In many ways one can say that Tarde has been founding the sociology and anthropology of markets. His key contribution is that far from adding social elements to the cold calculation of economics, Tarde shows that in order to quantify relations of attachements between people and goods, one has to take into account the psychological aspects. The more you psychologize it (in Tarde specific sense of intra and not inter psychology) the more you will be able to quantify it. He uses this argument to criticize Marxism, to expose the weaknesses of social darwininism, to propose a solution to the so called « Adam Smith’s problem » and has a myriad of other insights about a question which has never been more important than today. The foreword presents the program and summarizes the part that have been cut from this edition.

The paper starts by a visit to an exhibit at the Natural History Museum in New York which shows in parallel series of fossils of horse evolution and series of how paleontologists have varied in their reconstruction of this evolution. It is the occasion to test again an argument at the heart of science studies and history of science : is there a history of science ideas about nature, or also a history of the objects known by science. If the latter is the case, then do we have the philosophical ressource to think this change of conception through ? Using James, Fleck, Whitehead and more recent science studies results, the paper tries to « desepistemologize » knowledge on the one hand while « reontologizing » it on the other.

In a totally forgotten book, Etienne Souriau, a mid 20th century philosopher had very daringly proposed to tackle straight on the question of the plurivocity of being not, as is so often the case in the history of philosophy, by offering variations on the one central mode –that is knowledge- but by insisting that there might exist entirely different modes. Feeding on the key notion that prepositions too are given in experience, as James said, it is one of the most extraordinary enterprises to give flesh to James’ notion of pluriverse. Since the notion of mode of existence is so germane to the notion of regimes of enunciation, a close reading of Souriau’s book is called for.
