Experimentation, communication and patronage: a perspective on René-Antoine Ferchault de Réaumur (1683–1757)

Historians of science have neglected the French Academician Réaumur, whose work is emblematic of a modern conception of science that joins together technology, science, and society. Réaumur practised rigorous experimentation on organisms, and uncovered industrial and utilitarian secrets which he communicated to the public. His patronage was essential in boosting the generation of young naturalists of the 1740s who advanced further the experimental approach to the study of nature. For Réaumur, his work was not separate from his mission to disclose and communicate previously restricted knowledge for the benefits of science and society.

The mobile frontiers of Piaget's psychology : From academic tourism to interdisciplinary collaboration

Abstract Jean Piaget’s (1896–1980) interdisciplinarity was related to his psychology in several ways. First, he was a simple tourist of other fields: an interested outsider. But as he became increasingly involved in the professionalization of the discipline, he moved through different contexts that constrained the possibilities for successful action in new and different ways. To make these clear, we adopt a little-known aspect of his later epistemological framework: the open hierarchy of levels. This then affords new perspectives of his life, his work, his theory and his location in the history of both Swiss psychology and French psychology. It also outlines his reasoning regarding the necessity of a disciplined approach to interdisciplinary collaboration, institutionalized in the founding of his International Centre for Genetic Epistemology. We therefore come not only to a fuller understanding of how Piaget thought scientific knowledge develops, but also of how the boundaries of scientific disciplines are pushed back.

An epistemological history of time: From technology to representations

Abstract This paper attempts to link the social history of the mechanization of time with the history of the psychological notion of time. Historical processes such as the mechanization of tower clocks from the Middle Ages onwards, the reform of the Gregorian calendar and the quarrel of the Christian and Chinese calendars characterized the modern representation of time on three points: isochrony, desacralization and abstraction. While Western societies learned to domesticate the practical aspects of time, the scholars of the Enlightenment naturalized time. They considered it a concept only related to man and used quantified time for scientific purposes. Empiricists saw time as a product of the succession of thought while idealists considered it a form necessary for the human experience to occur. Both trends agreed in removing time from nature and accepted isochrony, desaralization and abstraction as the necessary foundation for the modern notion of time.

Fictitious Empiricism, Material Experiments. Conditions for Thinking the Enlightenment “Issue of Empiricism”

Historians of ideas currently believe that empiricism as a philosophy, a practice and a discourse was responsible for the very origin of modern science. In this paper, I call this idea into question by considering the semantic changes of words and expressions related to empiricism, experimentation and observation.
