you don't get it, huh?
With Spinoza, god essentially is nature. In deism, god is a separate entity.
Here's wiki on Spinoza's brand of religions:
Spinoza argued that God and Nature were two names for the same reality, namely the single substance (meaning "to stand beneath" rather than "matter") that underlies the universe and of which all lesser "entities" are actually modes or modifications, that all things are determined by Nature to exist and cause effects, and that the complex chain of cause and effect are only understood in part
Here's wiki on Deism:
Deism differs from theism in that according to Deism God does not interfere with human life and the laws of the universe.
Deists hold that religious beliefs must be founded on human reason and observed features of the natural world, and that these sources reveal the existence of one God or supreme being.
See the difference? Spinoza is not a deist.
Hence, these men see God within nature, but do not attribute such to divine inspiration.
No. They (E & S) do not see God within nature. God, rather, is nature.
Spinoza and Einstein are not deists.
