This is a great resource for the many different ethical systems complete with founders and definitions. This "Encyclopedia of Morals" by Vergilius Ture Anselm Ferm (Editor) is a hardback book of over 600 pages of information. No ethical student should be without this.

This fine volume, first published in the early 1950s, takes an interesting approach to the history of philosophy: it consists of a series of forty-odd essays, written by acknowledged scholars in the field, tracing the history of specific _systems_ of philosophy. The coverage is global; not only Greek and other Western philosophy are represented, but so are (e.g.) Indian, Chinese, and Buddhist philosophy. The essays are uniformly excellent -- as one might expect from the parade of familar names who wrote them: Gordon H. Clark, Henry Veatch, G. Watts Cunningham, Edgar Sheffield Brightman, Roy Wood Sellars . . . Moreover, each essay includes a helpful bibliography that serves as a guide to further reading. On the whole, this may still be one of the best introductions around to the history of philosophical thought.
