By MANNERS, I mean not here Decency of behaviour; as how one man should salute another, or how a man should wash his mouth, or pick his teeth before company, and such other points of the Small Morals; But those qualities of mankind that concern their living together in Peace and Unity. To which end we are to consider that the Felicity of this life consisteth not in the repose of a mind satisfied. For there is no such Finis ultimus (utmost aim) nor Summum Bonum (greatest good) as is spoken of in the books of the old Moral Philosophers. Nor can a man any more live whose desires are at an end than he whose Senses and Imaginations are at a stand.
