Scientific Explanation

Abstract

One of the major aims of science, it is commonly held, is to provide explanations. Philosophers of science have tried to understand what it is to provide a scientific explanation, what distinguishes good from bad explanations, and why explanations are valuable. This chapter goes through the main answers that have been elaborated in the last decades. It starts with a detailed discussion of the famous deductive-nomological (DN) model of explanation proposed by Hempel and Oppenheim. Then, the two main rivals to the DN model, the causal theory and the unificationist theory, are introduced and discussed. Some other contemporary approaches are sketched out in the closing section.
