ABSTRACT
Piaget has founded a discipline he calls genetic epistemology, which will be described shortly. According to Piaget (1970a, pp. 15–16) the first rule in this discipline is collaboration among specialists from diverse fields. Jean-Blaise Grize is one such specialist who participated at the Center for Genetic Epistemology in Geneva. In Piaget’s words (1963): “J. B. Grize is a pure logician, but one of the specialties that he shows at our Center is to grasp the interest of the specifics of psychogenetic analysis, and to invent . . . logical and algebraic models that correspond to the facts, not in their detail, but in their most important characteristics [p. 5].”
