Abstract

One of the few serious attempts undertaken during the last decade to develop a logic of questions. Belnap's theory comprises three parts so far: a) an informal syntactical treatment of the question-answer relationship, aimed at determining the policies involved in setting up a formalization of questions and answers; b) such a formalization itself ; and c) a semantical analysis leading to explicit definitions of adjectives like "rhetorical," "interesting," "foolish" as applied to questions; "direct," "complete," "corrective," and again "foolish" as applied to answers. This study is a remarkable contribution to a new and rather intricate field of logical inquiry.—A. Z. B.
