Abstract

Four essays of interest to the philosopher of science. The collection includes three short essays by L. P. Coonen, D. M. Lilly and C. DeKoninck. In the major essay, "Evolution: Scientific and Philosophical Dimensions," R. J. Nogar first presents a detailed analysis of the current status of the concept of evolution, showing that its meaning varies greatly from discipline to discipline. He argues that in view of the great stability of organic species, the consideration of evolutionary processes exclusively as space-time distributions in inadequate, and needs supplementing by a concept of "nature," to explicate the relation between generator and generated, and the facts of heredity.--K.
