 Cordemoy’s other important work, the Discours physique de la parole (A Physical discourse on speech), appeared in 1668, as did his Copie d’une lettre ecrite à un sçavant religieux de la Compagnie de Jésus (A Copy of a letter written to a learned religious of the Company of Jesus). The latter is Cordemoy’s attempt to reconcile Cartesian philosophy with the story of creation as found in the Book of Genesis. The former is an account of speech production, and its popularity led to Cordemoy’s being recognized as one of the more important French philosophers of his time. He was even the model for the character of the Master of Philosophy in Molière’s play Le Bourgeois Gentilhomme.
