Epicurus's great confidant and familiar, Colotes, set forth a book with this title to it, that according to the tenets of the other philosophers it is impossible to live. Now what occurred to me then to say against him, in the defence of those philosophers, hath been already put into writing by me. But since upon breaking up of our lecture several things have happened to be spoken afterwards in the walks in further opposition to his party, I thought it not amiss to recollect them also, if for no other reason, yet for this one, that those who will needs be contradicting other men may see that they ought not to run cursorily over the discourses and writings of those they would disprove, nor by tearing out one word here and another there, or by falling foul upon particular passages without the books, to impose upon the ignorant and unlearned.
