That which doth not hurt the city itself; cannot hurt any citizen. This rule thou must remember to apply and make use of upon every conceit and apprehension of wrong. If the whole city be not hurt by this, neither am I certainly. And if the whole be not, why should I make it my private grievance? consider rather what it is wherein he is overseen that is thought to have done the wrong. Again, often meditate how swiftly all things that subsist, and all things that are done in the world, are carried away, and as it were conveyed out of sight: for both the substance themselves, we see as a flood, are in a continual flux; and all actions in a perpetual change; and the causes themselves, subject to a thousand alterations, neither is there anything almost, that may ever be said to be now settled and constant. Next unto this, and which follows upon it, consider both the infiniteness of the time already past, and the immense vastness of that which is to come, wherein all things are to be resolved and annihilated. Art not thou then a very fool, who for these things, art either puffed up with pride, or distracted with cares, or canst find in thy heart to make such moans as for a thing that would trouble thee for a very long time? Consider the whole universe whereof thou art but a very little part, and the whole age of the world together, whereof but a short and very momentary portion is allotted unto thee, and all the fates and destinies together, of which how much is it that comes to thy part and share! Again: another doth trespass against me. Let him look to that. He is master of his own disposition, and of his own operation. I for my part am in the meantime in possession of as much, as the common nature would have me to possess: and that which mine own nature would have me do, I do.
