| Résumé anglais |
"Economies will progress as we deepen our understanding of human thought processes ; and economics will change as human individuals and human societies use progressively sharpened tools of thought in making their decisions and designing their institutions . A body of theory for procedural rationality is consistent with a word in which human beings continue to think and continue to invent ; a theory of substantive rationality is not" (HA. Simon, 1976, p, 146). Has'nt this strong conclusion of HA. SIMON to be seriously examined and discussed, particularly try Economics sciences ? Considering some of the main stages of the history of the concept of Rationality in the scientific thought, (Pre- socratics and Aristotle, R. Descartes and G.B. Vico, G. Boole and f.B. Grize...), the legitimity and the scope of the distinction proposed by HA. Simon between the two forms of rationality, "Substantive" and "Procédurale" are argumented. It is shown that the first one gives account of the deductive or syllogistic forms of reasoning as express today by the "formal logics", (based on the three axioms of syllogism formulated by Aristotle, usually with a confusion between formal Negation and meaningful Contradiction) ; and that the second one take in account the dialectical and rhetorical forms of reasoning, as expressed today by the "natural logics", based on some hypothesis of conjonctive and teleological plausibility and feasibility. The consequences of this distinction for the modeling of complex systems and of design of intervention in complex systems are briefly considered. Source : Éditeur (via Persée) |
