Ethics (Great Books in Philosophy) [first edition]

In the genre of Christian philosophers, Spinoza presents a geometric argument for the necessary existence of God as the one absolute substance underlying all other substance. From the necessity of God's existance, he derives the laws of existence, those of nature, and the ethical principles animating human conduct. In this sweeping volume that covers a wide range of topics from metaphysics, epistemology, and theology, Spinoza addresses the key concepts of freedom, the existence of evil, and the ultimate purpose of humanity.
