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.

So too the doctor seeks to heal the sick; but if the violence of the disease or the refusal of the patient to obey his regimen or any other circumstance prevent his achieving his purpose, he will not have fallen short of the ideals of his art, provided he has done everything according to reason. So too the orator's purpose is fulfilled if he has spoken well. For the art of rhetoric, as I shall show later, is realised in action, not in the result obtained.
