Abstract
In “Ruyer’s Relation to Whitehead”, Fabrice Colonna seeks to establish the exact presence of Whitehead in the French philosopher’s work. The indisputable points of connection between the two thinkers, concerning the importance of metaphysics, the critics of the materialistic scheme, the relevance of a renewed platonism, should nevertheless not obscure certain differences in emphasis, which are apparent in the problem of the compounds beings and about certain principles of speculative theology, to which both of them have found deeply original ways.
