The preceding Preface, which Professor William Frankena had the great kindness to write as an introduction for the readers of the present English translation of my major work, still requires several supplementary com- ments on my part. Professor Frankena rightly considered it to be an advan- tage to introduce the English-speaking world to my moral philosophy through its presentation in this book. As an introduction to my moral philosophy, Professor Frankena provided a concise formulation of the fun- damental ideas of my ethics by quoting from an article I had just recently published. Several points worth mentioning remain. Firstly, it is necessary to distinguish the two editions of the text here translated. The first edition was published in 1951 by Anton Hain in Meisenheim am Glan, under the title Pflicht und Neigung (Duty and In- clination), with the subtitle Die Grundlagen der Sittlichkeit, erOrtert und neu bestimmt mit besonderem Bezug auf Kant und Schiller (The Fun- damentals of Morality, Discussed and Redefined with Special Regard to Kant and Schiller).In 1974, a revised and enlarged second edition was published by the same publisher and was entitled Die Grundlagen der Sitt- Iichkeit (The Fundamentals of Morality). Of this second edition, the first four chapters have been translated in the present volume, along with four more recent essays.
