This paper describes Ajdukiewicz’s approach to non-deductive patterns of inference. At first, Ajdukiewicz’s treatment of inductive probability offered by him in the twenties is reconstructed. Generally speaking, for Ajdukiewicz at that time, an inductive rule is sound if it leads more often to true conclusions than to false ones. In the fifties, Ajdukiewicz developed a new theory of inductive inferences based on the decision theory, particularly on the concepts of profit and loss: a scheme of inductive inference is rational with respect to a given task determined by the balance of profits and losses if and only if the degree of confidence in the conclusion does not exceed the degree of the infallibility of the scheme in question.
