But in order that you may see whence all this born error is the pleasure of those who accuse and praise the 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 itself because it is a total pleasure, but because great pains result to those who do not know how to follow pleasure with reason.
