Abstract

This article analyzes the physical theory presented by Pierre Bayle in the new Spanish translation of Various Thoughts on the Occasion of the Comet. First, it deals with his critcism of the supertitous aspects of tradition, and subsequently, it analyzes his position, inspired by Descartes, regarding the physical nature of comets as opposed to the aristotelian cosmology, trough the analysis of five key issues: influence of distance, propagation of light, interaction between particles, difference between systems and problem of qualities.
