We take the notion of semiosis from Charles Sanders Peirce, through Charles W. Morris, in the sense that semiosis is "the process in which something functions as a sign" . On the other hand, the notion of sign we take from Ferdinand de in the sense that "by sign we mean the total resulting from the association of a signifier with a signified." : "Nous entendons par signe le total résultant de l'association d'un signifiant à un signifié".) By chemism we mean the chemical affinity and chemical reactivity of substances.
