by Baruch Spinoza (Author) This Collection includes most notable works of Baruch Spinoza - Ethics, Theologico-Political Treatise, On the Improvement of the Understanding. Ethics is undoubtedly Spinoza's greatest work - an elegant, fully cohesive cosmology derived from first principles, providing a coherent picture of reality, and a guide to the meaning of an ethical life, it defines in turn the nature of God, the mind, the emotions, human bondage to the emotions, and the power of understanding - moving from a consideration of the eternal, to speculate upon humanity's place in the natural order, the nature of freedom and the path to attainable happiness.
