Ryszard Kleszcz – Rationality and Requirements of Logic

In this paper I discuss the problem of rationality of beliefs. The standard model of rationality proposes three conditions: 1) proper articulation, 2) respecting the requirements of logic (“logical rationality”), 3) sufficient justification. The second condition is usually understood as two requirements: one concerning consistency, the other suitable deductive abilities. This idea of logical rationality (commonly accepted) is idealised and not used in practice. For this reason the idealized conception should be reformulated. The conception of minimal logical rationality requires the fulfilment of some conditions but it would not presuppose logical omniscience.
