A Burning Obsession: Cosmos and its Metaphysical Baggage

It is odd that a great scientific series on the cosmos should open with an attempt to single out one victim of the Inquisition and hold him up as a martyr to science. For inexplicable reasons, Cosmos: A Spacetime Odyssey begins not with Copernicus confidently proposing his heliocentric hypothesis or Galileo excitedly proclaiming his telescopic discoveries. Rather, it begins with the story of Giordano Bruno (1548-1600), a renegade Dominican friar executed in 1600 for persistently preaching heretical theological views about a wide variety of core Christian doctrines.

Of course, in 2014 we don't burn people at the stake, and except for the most conservative voices, Christians don't cast about casually labelling any dissenting theologial perspective as "heresy."

But Cosmos makes Bruno out to be a martyr who died heroically in the defense of early modern science, and this is a role he certainly did not play. Jole Shackleford details this nicely in his exploration of the myth that "Giordano Bruno was the First Martyr of Modern Science" in Ron Numbers' edited volume Galileo Goes to Jail and other Myths about Science and Religion (2009).

The idea of a reboot of the classic Cosmos series (1980) is exciting. The original series inspired in many people a deep and abiding love for science, and the revival has tremendous potential to expose a new generation to the wonder and value of science. I began watching Cosmos: A Spacetime Odyssey with great interest, in the hope of discovering some new perspectives on the fabulous story of our unfolding universe. Some new ideas are there indeed, and I will eagerly tune in to future episodes to see what else emerges. But I also saw—among the compelling video of the solar system and galaxies—considerable slipshod history of science and a curiously antireligious bias.

Thirty years ago Carl Sagan restated—no doubt with tongue in cheek—an ancient paean of praise from the Christian liturgy:  “The cosmos is all that is or ever was or ever will be.”  His echo of the Christian doxology—“As it was in the beginning, is now and ever shall be, world without end”—carried an implicit nontheistic metaphysical claim in setting the stage for his telling of the cosmic story. Neil deGrasse Tyson uses that same phrase for his own retelling of Cosmos.

To be fair, it is probably an impossible task for anyone completely to separate his understanding of the universe from his personal beliefs about the existence or nonexistence of meaning, purpose, and value in that universe. Consciously or unconsciously, all of us—Christian or Muslim, monotheist or atheist, freethinker or agnostic—carry the baggage of metaphysical beliefs in our approaches to science. If we are honest, we will explicitly acknowledge our metaphysical carry-on, recognizing that the story of this pulsing, vibrating, magnificently unfolding universe is susceptible of both theistic and atheistic interpretations.

Unfortunately, the series premiere risks squandering that opportunity through a combination of misleading history and reliance on an antiquated narrative of inevitable conflict between science and religion—and the Catholic Church in particular—that simply is not borne out by the facts. A generation of careful scholarship has given us a nuanced and sophisticated understanding of the long, rich, and complex relationship between religion and the sciences. This latest Cosmos reflects none of that historiography, presenting us instead with what is quite literally a cartoon version of the life story of someone who was not a scientist. Missing were the stories of Catholic astronomers such as Copernicus and Galileo, Protestants such as Brahe and Kepler and Newton, or Fr. George Lemaître, proposer of the Big Bang.

It is odd therefore that Cosmos focuses almost exclusively on the marginal case of Giordano Bruno. Of course, I am not defending Bruno's persecution and death—no decent human being now would ever condone burning a person alive for any reason. Moreover, in 2014 we view legitimate theological dissent very diffferently than did our ancestors.

But the circumstances were quite different 400 years ago. According to the 16th century Italian legal code and the customs of Renaissance politics, Bruno was judged by an ecclesiastical court to be an obdurate heretic for refusing to cease in promulgating his theological ideas. As such he was subject to capital punishment and was turned over for execution by the civil arm in Rome. [*Editor note: The preceding sentence originally said Bruno was "deserving of" capital punishment. Clearly a misstatement on our part!] In the 21st century we inhabit a very different era, a religiously pluralistic age of largely secular states in which the nature and exercise of authority are vastly different than they were in Post-Reformation Italy.

The relevant question about this unfortunate affair—in the context of Cosmos: A Spacetime Odyssey—is whether Bruno was executed for his scientific or for his theological views.Championing the plurality of worlds (contrary to the teaching of Aristotle) was a comparatively less significant doctrinal fault than some others. The most serious charges lodged against Bruno included:
