But that you may see from whence all this error of accusing pleasure and praising pain arises, 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 the blessed life. For no one despises or hates or flees pleasure itself because it is pleasure, but because great pains follow those who do not know how to follow pleasure with reason. Nor is there any one who loves, pursues, or wishes to obtain pain itself because it is pain, but because such times as these occur not infrequently that he seeks some great pleasure through toil and pain. For to come to the smallest detail, which of us undertakes any laborious exercise of the body?
