A solid history of the growth of the scientific method from the early Greeks to the present, that examines the needs science fulfills for man and is wisely selective in its illustrations. First the author quickly surveys the development of both natural and social science and the tie between science and art. Amplifying his introduction he goes briefly into the important stages from Thales to Newton and Darwin, explains how scientific knowledge differs from other knowledge by its method of theory and experimentation and its goal of prediction, and comments on the experimental limitations of sociology. By positing that we need to know to enjoy, he then connects art and science, extending the artist's knowledge of truth to a comparison of the scientific to the artistic creative imagination. Altogether a clear volume for a simple but challenging picture of science today.
