The totality of existence, Nature, God, is far above us, and is indifferent to our desires and aspirations, - gone is the notion of a personal God. As for the notions of good and evil, they exist, but only to the extent that they fit our own personal inclinations. Spinoza's most important work was entitled Ethics , published about a year after his death. To Spinoza, the guiding goal of man is self-preservation, it is an instinct which we feel in the emotion of desire. The mental capacity to reason is naturally available to all.
Reason is a powerful instrument by which one is able to guide one's life.
In this regard Spinoza was a determinist. P.O. Box 1200, Dartmouth, Nova Scotia.
