Abstract
The work of Hegenberg is more than a simple translation into Portuguese of major parts of the body of current work in the philosophy of science. Behind his thorough work of research and compilation, behind the remarkable clarity and succinctness in the exposition of vast amounts of material, lies an expert organization of theories and problems that promises original contributions by the author in some of the areas here surveyed. After a philosophical preamble on belief, science, and philosophy, Hegenberg advances a general analysis of scientific explanation embracing both deductive and probabilistic explanations. In an extensive third part he deals with the attitudes toward determinism in contemporary science, and with particular kinds of explanation such as teleological, psychological, sociological, and historical explanatory structures. Without abandoning the basic thesis of the unity of science, the author shows in this last part a great awareness of the distinct problems posed by explanation in every one of those fields. The bibliographical references after each chapter are rather complete, though references are missing concerning the most recent work in structural linguistics, economics, and anthropology.--A. M.
