Probabilità e induzione / Induction and probability

Introduction CONCEPTUAL OUTLINE OF THIS COLLECTION OF PAPERS A few introductory words may serve to guide the reader through the diverse topics of these collected papers. In a manner of speaking, there is only one the role of probability—interpreted always as subjective probability—in thinking and acting. The assessing of probabilities, as expressions of subjective feeling, and reasoning with probabilities, obeying objectively necessary conditions of coherency, constitute the logic of uncertainty; they are the general tools of our minds along with formal logic, which is concerned with the ideal case of absolute certainty.
