"Harrison is no nostalgic reactionary. He acknowledges modernity’s gifts. But he warns against monochrome narratives of progress. One of his most provocative claims is that science, too, relies on “ implicita.” …As a scholar of new religious movements, I find Harrison’s thesis electrifying. He doesn’t mention my field, but I’ll extend his argument: many new religions are a renaissance of “fides implicita.” Converts don’t join because they’ve dissected theological treatises (although some may read them later). They join because they trust a guru, a prophet, a community. Just like early Christians and Muslims. The intellectual scaffolding may come later—or not at all. So, is “fides implicita” obsolete? Has secular science vanquished religion? Harrison—and I—say: not so fast. Belief, in its ancient form as trust, is alive and well. It’s just wearing new clothes."
