 Though it is in the Discernement that we find the basics of Cordemoy’s philosophy, it was his Discours physique de la parole which was most identified with him. (Unlike the Discernement, the Discours was translated into English during Cordemoy’s lifetime.) The Discours opens with the question of other minds: while I know that I am a thinking thing, how can I be certain that other humans are—might not they be mindless automata who only behave as if there were clever thoughts behind their behavior? Following Descartes, Cordemoy claims that it is other humans’ use of language—both in its complexity and its creativity—which assures me that they have minds, in that such communication cannot be explained on mechanical principles alone. Cordemoy then concludes this discussion, saying: “Now that it is no longer possible for me to doubt that the bodies which resemble mine are united to souls, and since I am sure that there are other men than me, I think that I ought to look with care at what remains to be known about speech” (1968, 209). The remainder of the Discours is taken up with this investigation.
