Vibrations cosmiques: Échos de l’harmonie universelle aux temps des Lumières britanniques

This paper argues that the medieval conception of musica mundana and musica humana, the idea that the universe and man are musically constructed, had an afterlife in the Enlightenment. The musical paradigm essentially dropped out of use in the seventeenth century, and was replaced by versions of Cartesian mechanism. However, by focusing on the ideas of certain British natural philosophers I show how they absorbed aspects of the harmonia mundi tradition, especially the theory that the universe is filled with a vibrating ether or spirit that also serves as the connection between body and soul.
