Proposes an interrogative approach to conceptualizing the rationality of scientific inquire, which has eluded such approaches as inductivism, hypothetico-deductivism, and reductionism. Discusses the concept of the logic of discovery, traditional logics, the interrogative-dialogical model and a new version of it. As a case study, applies it to the geological problem of the K-T boundary mass extinction. Revised from a doctoral dissertation apparently for the University of Georgia; no date noted.
