Stuart Hampshire, one of the most eminent British philosophers of the twentieth century, will be perhaps best remembered for his work on the seventeenth-century philosopher Spinoza, all of which is gathered now in this volume. Among the great thinkers of modern times, only Spinoza created a complete system of philosophy that rivals Plato's, with crucial contributions to every major philosophical topic. Hampshire's classic 1951 book Spinoza remains the best introduction to this thinker, and it is reprinted here. But what gives particular interest to this new volume is the first publication of Hampshire's last work "Spinoza and Spinozism," an extended presentation of a Spinozist philosophical worldview. Hampshire's influential 1962 essay "Spinoza and the Idea of Freedom" is also included.Spinoza and Spinozism is thus an ideal companion to the study and interpretation of this great philosopher.
