Information and Induction : A Subjectivistic View of Some Recent Results.

Dean T. Jamison

Expert InsightsPublished 1968

A subjectivistic theory of logical induction, expressed in decision-theoretic terms, that allows the logical systems of Carnap and Hintikka to appear as special cases. The basic concept is that semantic information is change in belief, as reflected in change in subjective probabilities. Rules governing inductive inferences may be regarded as rules for acquiring semantic information. Second-order, and in some cases third-order, probability distributions are used. The Carnapian system is generalized by allowing any desired number of alternatives instead of merely two-valued predicates, such as red or not red. A Bayesian mechanism for certain types of concept formation leads to a subjectivistic generalization of Hintikka's two-dimensional continuum of inductive methods. 46 pp. Ref.
