Wesley C. Salmon was University Professor of Philosophy at the University of Pittsburgh. He devoted his main research efforts to causality and explanation and to probability, induction, and confirmation. Among his major works are Scientific Explanation and the Causal Structure of the World (1984) and Causality and Explanation (1998).

Salmon was an important contributor to various debates in the area and the lucidity of his prose makes the great majority of the essays accessible to the full spectrum of readers, from undergraduates to professional philosophers. This collection of essays will provide a fitting tribute to one of the best philosophers of science in the twentieth century. It contains arguments of permanent value and each is written in the limpid style that makes Salmon such a delight to read.
