Spinoza is a pantheist. He believes that all is God. There is no transcendence from the Creation. There isn't a Creation. The Absolute is the indwelling, not the transient cause of the universe.
All existence is eternal.
All substance is infinite. This is truly only one substance, since no two substances can share the same attributes. Spinoza, a Dutch philosopher, held the view that mind and body were just two aspects of the same one reality. This is pantheistic, or the belief that all is God. Mental reality is subjective or internal, and bodily reality is objective or external.
