Frances A. Yates to Hominids

Frances Yates traced how Renaissance occultism smuggled scientific ambition past the Church's gatekeepers — the Rosicrucian Enlightenment wasn't anti-faith, it was faith repurposed as an engine of inquiry, reason wearing a mystical costume to survive. That tension between faith and reason doesn't resolve; it just changes venue. James Blish understood this perfectly in *A Case of Conscience*: a Jesuit biologist encounters an alien species that appears morally perfect without any concept of God, and the discovery doesn't settle the debate — it detonates it, because a rational creation without a Creator is either proof of grace or the Devil's finest trick. The "alien" doesn't have to arrive on a spaceship. Sawyer's *Hominids* makes the move literal: the alien is a Neanderthal, a hominid cousin from a parallel Earth where *Homo sapiens* went extinct, and contact with him forces every character to re-examine what they assumed was uniquely, even divinely, human. Each hop on this path is the same door opening wider — from Yates's magicians who needed esoteric cover to practice science, through Blish's priest who needed theology to survive science, to Sawyer's modern humans who discover that conscience, culture, and moral reasoning are not their exclusive inheritance.
