The better man you have to look at

"[701a] For, thinking themselves knowing, men became fearless; and audacity begat effrontery. For to be fearless [701b] of the opinion of a better man, owing to self-confidence, is nothing else than base effrontery; and it is brought about by a liberty that is audacious to excess."
