The enemies of Fabius thought they had sufficiently humiliated and subdued him [...], but they mistook the temper of the man, who looked upon their derision as nothing of concern, like the great philosopher Diogenes, who of being told that some people were mocking him, answered, "But I am not mocked." meaning that you can only be insulted if those insults make an impression upon you.

So Fabius, with great tranquillity and unconcern, continued upon his course, therefore proving the age old maxim that, "A virtuous man who is just and good, is not capable of being dishonoured." - Plutarch's Lives, Fabius Maximus
