From Laura Miller’s “Everybody loves Spinoza” (Salon: 17 May 2006):
Key to Spinoza’s heresy was his monism, his belief that everything that exists is essentially a single thing, “nature” (that is, the infinite universe), and that this is identical with God. (As a girl, Goldstein was taught that Spinoza wickedly equated God with nature, when Jews and Christians agreed that God is supernatural, outside of nature, and a person.) Everything we experience — people, events, objects — is simply a “mode” of that single “Substance” or essence. Because God/Nature is infinite and we are finite, we perceive these things to be separate when they are not; all separate identities, including our own individuality, are merely an illusion or misperception. We perceive good and evil when neither really exists, from the perspective of God. The only way we can come to understand the true unity of the world is through the understanding of pure reason, which is integral to Substance in the same way that roundness is integral to a circle.
We can’t fully grasp this — our minds aren’t adequate to the task — but with a dash of intuition, we can glimpse it and experience Spinoza’s notion of true happiness. We can then attain what Goldstein calls a “radical objectivity,” a perspective that’s outside of our own limited identity. This objectivity will enable us to see the insignificance of our own pains, pleasures and losses except insofar as they help or hinder our ability to reason. We will realize that a life of restraint and peaceful coexistence with our fellow man is exactly what will sustain us in this cause; self-interest and virtue will be revealed as identical. Finally, we will be able to regard with tranquility the fact that we are mortal, that our minds, like our bodies, are simply a mode of the great infinity of Substance, and will someday end.
