Benedict de Spinoza is one of the most controversial and enigmatic thinkers in the history of philosophy. His greatest work,Ethics (1677), developed a comprehensive philosophical system and argued that God and Nature are identical. His scandalousTheological-Political Treatise (1670) provoked outrage during his lifetime due to its biblical criticism, anticlericalism, and defense of the freedom to philosophize. Together, these works earned Spinoza a reputation as a singularly radical thinker.In this book, Steinberg and Viljanen offer a concise and up-to-date account of Spinozas thought and its philosophical legacy. They explore the full range of Spinozas ideas, from politics and theology to ontology and epistemology. Drawing broadly on Spinozas impressive oeuvre, they have crafted a lucid introduction for readers unfamiliar with this important philosopher, as well as a nuanced and enlightening study for more experienced readers.Accessible and compelling,Spinoza is the go-to text for anyone seeking to understand the thought of one of historys most fascinating thinkers.
