His theorems suggest otherwise, showing that even the most concrete and natural mathematical statements — involving nothing more exotic than rational numbers — cannot be proved or refuted within the gold standard of mathematical foundations, ZFC. The foundations of mathematics, Friedman argues, are not settled bedrock but something far more vertiginous: totally up in the air, and made more mysterious, not less, by his own work.
