In 1656 Baruch Spinoza abandoned his family’s import business to dedicate his life to philosophy. He quickly became notorious across Europe for his views on God, the Bible, and miracles, as well as for his uncompromising defense of free thought. Yet the radicalism of Spinoza’s views has long obscured that his primary reason for turning to philosophy was to answer one of humanity’s most urgent questions: How can we lead a good life and enjoy happiness in a world without a providential God? In Think Least of Death Steven Nadler connects Spinoza’s ideas with his life and times to offer a compelling account of how the philosopher can provide a guide to living one’s best life.
