The orator then, whom I am concerned to form, shall be the orator as defined by Marcus Cato,
a good man, skilled in speaking.[*](cp. I. Pr. 9. ) But above all he must possess the quality which Cato places first and which is in the very nature of things the greatest and most important, that is, he must be a good man. This is essential not merely on account of the fact that, if the powers of eloquence serve only to lend arms to crime, there can be nothing more pernicious than
Nature herself will have proved not a mother, but a stepmother with regard to what we deem her greatest gift to man, the gift that distinguishes us from other living things, if she devised the power of speech to be the accomplice of crime, the foe to innocency and the enemy of truth.

The reasons for this are, first, that vileness and virtue cannot jointly inhabit in the selfsame heart and that it is as impossible for one and the same mind to harbour good
