But in order that you may see whence all this born error of those who accuse pleasure and praise pain, I will open the whole matter, and explain the very things which were said by that discoverer of truth and as it were the architect of a happy life. For no one despises or hates or runs away from pleasure because it is pleasure, but because great pains result to those who do not know how to follow pleasure with reason. Nor, moreover, is there any one who, because he loves pain, pursues it, wants to gain it, but because such times never occur when he seeks some great pleasure through labor and pain. For to come to the smallest detail, which one of us undertakes any physical exercise that is laborious, except in order to derive some benefit from it? But who can rightfully criticize him who wants to be in that pleasure which results in no discomfort, or he who avoids that pain in which no pleasure is produced?

But indeed we both accuse and with just hatred bring those who deserve it who are softened and corrupted by the flattery of present pleasures, blinded by lust for the pains and troubles they are about to experience, they do not provide for it. And indeed the distinction between these things is easy and expedient. For in free time, when we are free to choose and nothing prevents us from doing what pleases us the most, all pleasure must be assumed, all pain rejected. But at certain times, and either due to duties or the necessities of things, it will often happen that both pleasures are to be rejected and troubles are not to be rejected. And so the choice of these things is held by a wise man, so that either by rejecting greater pleasures he may obtain others, or by enduring pains he may repulse more severe ones.
