" As for the other aspect, creative or signed enunciation, it is clear that scientific propositions and their correlates are just as signed or created as philosophical concepts: we speak of Pythagoras’s theorem, Cartesian coordinates, Hamiltonian number, and Lagrangian function just as we speak of the Platonic Idea or Descartes’s cogito and the like. But however much the use of proper names clarifies and confirms the historical nature of their link to these enunciations, these proper names are masks for other becomings and serve only as pseudonyms for more secret singular entities "
