O’Connor and the Will to Stupidity
As Kermit Roosevelt (huh?!) mentions in the American Prospect, former Supreme Court Justice Sandra Day O'Connor is said to have had an embroidered cushion in her office that read “Maybe in error, but never in doubt”.

That is of course from Nietzsche (Beyond Good and Evil).
