 Material dialogues have in fact been included in the dialogical framework from the start, as Krabbe (1985: 297) points out. Material dialogues indeed had priority over formal dialogues in Lorenzen and Lorenz’s work (Kamlah &amp; Lorenzen 1967 [1972]; Lorenz 1961, 1968). However, Krabbe further points out that the standard dialogical framework developed thereafter did not focus on the material dialogues; he interprets this fact as a sign that formal dialogues had, after all, priority over material dialogues in the dialogical framework.
