Neil Degrasse Tyson’s remake of Cosmos tries to remake Giordano Bruno as a martyr of modern science, but he was nothing of the kind.
He was a lot more of an occultist. Even The Daily Beast gets it.
As Discover magazine’s Corey Powell pointed out, the philosophers of the 16th century weren’t anything like scientists in the modern sense. Bruno, for instance, was a “pandeist,” which is the belief that God had transformed himself into all matter and ceased to exist as a distinct entity in himself. He believed in all sort of magic and spirits, and extrapolated those views far beyond his ideas about the infinity of the universe. In contrast to contemporaries who drew more modest conclusions from their similar ideas, Bruno agitated for an elaborate counter-theology, and was (unlike the poor, humble outcast portrayed in Cosmos) supported by powerful royal benefactors. The church didn’t even have a position on whether the Earth orbited the sun, and didn’t bring it up at Bruno’s trial. While the early-modern religious persecution certainly can’t be denied, Bruno was killed because he flamboyantly denied basic tenets of the Catholic faith, not because religious authorities were out to suppress all “freedom of thought.”
