What would a revolution on the scale of the Copernican look like today? Sigmund Freud, whose works students and I discussed today in class, liked to pat himself on the back for his accomplishments, comparing himself to fellow paradigm-shifters Copernicus and Darwin. He believed the three of them had dealt “bitter blows” to humanity’s “craving for grandiosity.” Copernicus taught humans to de-center themselves, the earth a mere speck in a world-system of vast magnitude. Darwin robbed them of their self-regard — their sense of themselves as special, divine creations. Both figures dealt blows, in other words, to what Freud called humanity’s “Ego.” Why is the marriage of heaven and hell that Blake envisioned recast by Freud as cause for pessimism regarding humanity’s capacity for happiness? What happens when Blake’s “angels” and “devils” become Freud’s Superego and Id?
