Science and the Enlightenment is a general history of eighteenth-century science covering both the physical and life sciences. It places the scientific developments of the century in the cultural context of the Enlightenment and reveals the extent to which scientific ideas permeated the thought of the age. The book takes advantage of recent scholarship, which is rapidly changing our understanding of science during the eighteenth century. In particular it describes how science was organized into fields that were quite different from those we know today. Professor Hankins's work is a much needed addition to the literature on eighteenth-century science. His study is not technical; it will be of interest to all students of the Enlightenment and the history of science, as well as to the general reader with some background in science.
