Institutio Oratoria

However, let us fly in the face of nature and assume that a bad man has been discovered who is endowed with the highest eloquence. I shall none the less deny that he is an orator. For I should not allow that every man who has shown himself ready with his hands was necessarily a brave man, because true courage cannot be conceived of without the accompaniment of virtue.

Surely the advocate who is called to defend the accused requires to be a man of honour, honour which greed cannot corrupt, influence seduce, or fear dismay. Shall we then dignify the traitor, the deserter, the turncoat with the sacred name of orator? But if the quality which is usually termed goodness is to be found even in quite ordinary advocates, why should not the orator, who has not yet existed, but may still be born, be no less perfect in character than in excellence of speech?
