 There are, Spinoza insists, two sides of Nature. First, there is the active, productive aspect of the universe—God and his attributes, from which all else follows. This is what Spinoza, employing the same terms he used in the Short Treatise, calls Natura naturans, “naturing Nature”. Strictly speaking, this is identical with God. The other aspect of the universe is that which is produced and sustained by the active aspect, Natura naturata, “natured Nature”.
