Abstract
Father Copleston’s now established series of textbooks on the history of philosophy divides progressively like a live cell. Vol. I expounded Greek philosophy, Vols. II and III examined Mediaeval and Renaissance philosophy and Vol. IV, which was originally intended to cover modern philosophy from the 17th to the 19th century, expands now into three monographs dealing respectively with classic Rationalism, British Empiricism and the continental Enlightenment of the 18th century up to Kant. Thus the present volume, after a general Introduction which states the broad currents of thinking and makes the qualifications appropriate to offset their artificial discussion in three separate books, concentrates upon the personal and capital philosophies of Descartes, Spinoza and Leibniz.
