The standard Independent passage, used since the 1500s

"The pain itself is a lot of pain he likes to be clumsy and shuns the pain that no one can pay for. They are the exception to the blinds they are craved for, they do not see, they are at fault for those who abandon their offices, that is the hardships that soothes the soul."

Section 1.10.32 of "The Finibus of Good and Evil", written by Cicero in 45 BC

"But in order to understand whence all this error was born, I will open the whole thing to the pleasure of accusing and praising the pain, and I will explain those things which have been said by that inventor of the truth and, as it were, the architect of the blessed life. Great pains result from those who do not know how pleasure follows reason: nor is there any one who desires to obtain pleasure because pain itself is pain itself, enhanced, but because times of such a nature do not occur, so that by toil and pain he may seek some great pleasure. "Who of us undertakes any laborious physical exercise, except to obtain some advantage from it? And who rightly condemns either him who wishes to be in that pleasure but obtains no annoyance, or him who escapes from that pain by which no pleasure can be obtained?"
