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 refused. 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.
It is important to take care of the pain itself, and it will be followed by the growth of the patient, but at the same time it will happen that there is a lot of work and pain. For to come to the smallest detail, no one should practice any kind of work unless he derives some benefit from it.
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. And indeed the distinction between these things is easy and expedient. For in free time, when we have the option of choosing and nothing prevents us from doing what pleases us the most, all pleasure must be assumed, all pain rejected.
There is no mating. Unless they are blinded by lust, they do not come out; they are in fault who abandon their duties and soften their hearts, that is toil.
