ТЕОРИЯ НА ОСНОВАТЕЛНИТЕ РЕШЕНИЯ: ПАРАДОКСЪТ НА АЛЕ И ЛОГИКАТА НА ДЕЙСТВИЕТО.

The present paper introduces a novel formalism for analysis of practical arguments, called reason-based decision theory. In (§1) I provide an analogy between logic and decision theory, motivated by the role that reasons play in both fields of inquiry. (§2) elaborates on the idea of reason-based choice proposed by Shafir, Simonson, and Tversky (1993). In (§3) I illustrate ho this idea can be applied to the analysis of the famous paradox of Allais. (§4) s etches the logical formalism of reason-based decision theory, hile (§5) presents the different forms of practical argumentation. It is shown that they are sufficient for the solution of any dilemma. Finally, (§6) provides a game-theoretical semantics of the logical formalism and discusses the possibilities for its further elaboration. [ABSTRACT FROM AUTHOR]
