My opponents further assert that every art has some definite goal towards which it directs its efforts, but that rhetoric as a rule has no such goal, while at other times it professes to have an aim, but fails to perform its promise. They lie: I have already shown that rhetoric has a definite purpose and have explained what it is.

And, what is more, the orator will always make good his professions in this respect, for he will always speak well. On the other hand this criticism may perhaps hold good as against those who think persuasion the end of oratory. But our orator and his art, as we define it, are independent of results. The speaker aims at victory, it is true, but if he speaks well, he has lived up to the ideals of his art, even if he is defeated.
