Connu et étudié pour ses écrits philosophiques, moraux et politiques, J.-J. Rousseau s'est également intéressé à la botanique. A. Cook étudie cet aspect moins connu de l'oeuvre du penseur, et montre les relations entre cette activité apparemment marginale et sa philosophie, à partir d'un corpus de textes et documents de la main du philosophe ou extraits de sa bibliothèque. ©Electre 2026

Quatrième de couverture

Universally studied for his writings on politics, philosophy, morality and education, Jean-Jacques Rousseau's interest in botany has been deemed a mere curiosity. In this radical reinter pretation Alexandra Cook demonstrates how this seemingly marginal activity shaped and was shaped by his philosophy.

Rousseau's botanical project was informed by his belief in the superiority of nature over artifice - a principle illustrated in his famous Lettres élémentaires sur la botanique, in which he used the 'natural method' of plant classification, a ground-breaking system which would eventually triumph over rival systems. Based on a wide range of original sources, Cook traces and reassesses Rousseau's botanical education, the complex history of his plant collections, and his participation in scientific correspondence networks. She also reveals how his botanical writings were manipulated and misinterpreted following his death.

In this richly illustrated study, supported by inventories of his botanical library, correspondents and herbaria, Cook provides an unprecedented insight into Rousseau's study and practice of botany. Not simply an intellectual pursuit, it became part of his physical and psychological self-discipline, a precursor to today's 'environmental therapy'.
