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.

Most writers on the emotions and on human conduct... attribute human infirmities and fickleness, not to the power of nature in general, but to some mysterious flaw in the nature of man... -from Ethics Considered a rationalist in the ranks of Descartes and Leibniz, Benedict De Spinoza was so unorthodox in his philosophies that his writings, published in 1678 just after his death, were immediately banned in his homeland of Holland. The spreading influencing of his thinking could not be stopped, however, and Spinoza overarching contention-that human happiness could be achieved only through a reasoned understanding of the universe-remains provocative and significant today. This collection, translated from Latin by R.H.M. Elwes and published in 1901, brings together Spinoza's best known work, Ethics, in which he postulates that God and Nature constitute one deterministic system, a single divine machine, in which humans are a vital part; his treatise "On the Improvement of the Understanding," in which he discusses the very nature of the mind itself; and a selection of his correspondence that elucidates his reasoning.
