"I don't believe Fermat had a proof. I think he fooled himself into thinking he had a proof"
About this Quote
The intent is corrective, almost hygienic. Fermat’s Last Theorem became famous less for its statement than for the promise attached to it: “I have a truly marvelous proof.” That line turned an open problem into a legend, a dare passed across generations. Wiles, who spent seven years in secrecy and still had to repair a fatal gap, knows exactly how seductive it is to believe you’re done when you’re merely close. His remark subtly defends the culture of proof itself: not vibes, not confidence, not reputation, but a chain of arguments sturdy enough to survive hostile reading.
The subtext also protects Wiles’s own accomplishment from the shadow of myth. If Fermat had a complete proof all along, modern triumph becomes mere rediscovery. By denying that, Wiles asserts the real historical texture: mathematics advances by building new machinery, not by unlocking a forgotten drawer.
Context matters: Wiles solved the theorem using 20th-century tools (elliptic curves, modular forms) Fermat couldn’t have had. The quote isn’t disrespect; it’s a demystification of genius, and a reminder that certainty is often the last illusion to die.
