Berthoff, A. (1996). Problem-dissolving by triadic means. College English, 58 ( 1), 9-2 1.
Wow. By this time, Berthoff has her spiel down to the bone:
“In a triadic semiotic, the meaning relationship is conceived as having three terms: the symbol (or representamen, as C.S. Peirce called it), its referent (or object), and the interpretant, Peirce’s term for the idea which mediates the representation and what it represents” (my emphasis).
