The Oxford Philosophical Texts series consists of truly practical and accessible guides to major philosophical texts in the history of philosophy from the ancient world up to modern times. Each book opens with a comprehensive introduction by a leading specialist which covers the philosopher's life, work, and influence. Endnotes, a full bibliography, guides to further reading, and an index are also included. The series aims to build a definitive corpus of key texts in the Western philosophical tradition, forming a reliable and enduring resource for students and teachers alike. One of the classical texts of philosophy, Spinoza's Ethics is also one of the most difficult to understand. It discusses the nature of human beings, the way in which a rational person might live, the nature of God, and true freedom and how it can be attained. This volume features a new, lucid translation of Ethics enhanced by a comprehensive guide to Spinoza's work. An extensive introduction includes a short biography of Spinoza; help in understanding the form of Spinoza's writing and his own particular use of definitions; an introduction to the philosophy of Ethics; and a summary of Ethics. Further aids include a glossary of terms, notes to the text, and notes to the translation.
