Instead of lists of books for collateral reading, placed at the end of chapters or of the book, the student will find references in the footnotes to the exact pages of many helpful books. I should like to call the student’s attention to an appendix to the discussion of Plato. This is a complete selection of passages from Plato made by the late Professor Jowett for English readers. This selection Professor Jowett was accustomed to distribute to his Oxford class, of which I was once fortunate to be a member.
Philosophical terms have been defined either in the text or in the footnotes. Such definitions must necessarily have as their aim their usefulness to the student, rather than their completeness.

PREFACE TO THE REVISED EDITION
The only change which the reader will find in the revision of this volume is in the form of presentation of the philosophies of the earlier cosmologists (Chapter II).
