Book VII · Chapter 68

It is in thy power to live free from all compulsion in the greatest tranquillity of mind, even if all the world cry out against thee as much as they choose, and even if wild beasts tear in pieces the members of this kneaded matter which has grown around thee. For what hinders the mind in the midst of all this from maintaining itself in tranquillity and in a just judgment of all surrounding things and in a ready use of the objects which are presented to it, so that the judgment may say to the thing which falls under its observation: This thou art in substance [reality], though in men's opinion thou mayest appear to be of a different kind; and the use shall say to that which falls under the hand: Thou art the thing that I was seeking; for to me that which presents itself is always a material for virtue both rational and political, and in a word, for the exercise of art, which belongs to man or God. For everything which happens has a relationship either to God or man, and is neither new nor difficult to handle, but usual and apt matter to work on.
