Abstract

In “Ruyer, Leibniz and the Unity of Bodies”, Bertrand Vaillant addresses the problem of the unity of bodies as inherited from Leibniz by French philosopher Raymond Ruyer (1902-1987). He examines Ruyer’s metaphysical solution, a “corrected monadology”, in the light of this Leibnizian influence. He intends to show that this solution, designed to avoid the difficulties raised by Leibniz’ metaphysics, doesn’t quite succeeds in that respect.
