This chapter is the second part of the diptych devoted to adaptations of Russell’s notion of logical construction. It focuses on Jean Nicod’s thesis, “La géométrie dans le monde sensible,” published posthumously in 1924. Nicod (1893–1924) reverses Russell’s notion of logical construction to respond to Bergson’s argument according to which the mathematization of experience constitutes a “vicious” betrayal of immediate consciousness. Nicod argues that if experience can be completely described without introducing any geometric notions (as Bergson maintains), the spatialization of the sensible world, far from constituting a betrayal, reveals hidden virtualities of what is delivered in perception. We emphasize that while Nicod (in a sense) logicizes Bergson, he also profoundly renews Russell’s method of logical construction.
