XVIII. These three things thou must have always in a readiness: first concerning thine own actions, whether thou doest nothing either idly, or otherwise, than justice and equity do require: and concerning those things that happen unto thee externally, that either they happen unto thee by chance, or by providence; of which two to accuse either, is equally against reason. Secondly, what like unto our bodies are whilest yet rude and imperfect, until they be animated: and from their animation, until their expiration: of what things they are compounded, and into what things they shall be dissolved. Thirdly, how vain all things will appear unto thee when, from on high as it were, looking down thou shalt contemplate all things upon earth, and the wonderful mutability, that they are subject unto: considering withal, the infinite both greatness and variety of things aerial and things celestial that are round about it. And that as often as thou shalt behold them, thou shalt still see the same: as the same things, so the same shortness of continuance of all those things. And, behold, these be the things that we are so proud and puffed up for. XIX. Cast away from thee opinion, and thou art safe. And what is it that hinders thee from casting of it away? When thou art grieved at anything, hast thou forgotten that all things happen according to the nature of the universe; and that him only it concerns, who is in fault; and moreover, that what is now done, is that which from ever hath been done in the world, and will ever be done, and is now done everywhere: how nearly all men are allied one to another by a kindred not of blood, nor of seed, but of the same mind. Thou hast also forgotten that every man's mind partakes of the Deity, and issueth from thence; and that no man can properly call anything his own, no not his son, nor his body, nor his life; for that they all proceed from that One who is the giver of all things: that all things are but opinion; that no man lives properly, but that very instant of time which is now present. And therefore that no man whensoever he dieth can properly be said to lose any more, than an instant of time.
