First published in 1963, this title considers the philosophical problems encountered when attempting to provide a clear and general explanation of scientific principles, and the basic confrontation between such principles and experience. Beginning with a detailed introduction that considers various approaches to the philosophy and theory of science, Israel Scheffler then divides his study into three key sections - Explanation, Significance and Confirmation - that explore how these complex issues involved have been dealt with in contemporary research. This title, by one of America's leading philosophers, will provide a valuable analysis of the theory and problems surrounding the Philosophy of Science.
