 The Ethics is an ambitious and multifaceted work. It is also bold to the point of audacity, as one would expect of a systematic and unforgiving critique of the traditional philosophical and theological conceptions of God, the human being and the universe, especially as these serve as the foundation of the major organized religions and their moral and ceremonial rules. What Spinoza intends to demonstrate (in the strongest sense of that word) is the truth about God, nature and especially ourselves, and the most certain and useful principles of society, religion and the good life. Despite the great deal of metaphysics, physics, anthropology and psychology that take up Parts One through Three, Spinoza took the crucial message of the work to be ethical in nature. It consists in showing that our happiness and well-being lie not in a life enslaved to the passions and to the transitory goods we ordinarily pursue, nor in the related unreflective attachment to the superstitions that pass as religion, but rather in the life of reason. To clarify and support these broadly ethical conclusions, however, Spinoza must first demystify the universe and show it for what it really is. This requires laying out some metaphysical foundations, the project of Part One.
