XX. Let thy thoughts ever run upon them, who once for some one thing or other, were moved with extraordinary indignation; who were once in the highest pitch of either honour, or calamity; or mutual hatred and enmity; or of any other fortune or condition whatsoever. Then consider what's now become of all those things. All is turned to smoke; all to ashes, and a mere fable; and perchance not so much as a fable. As also whatsoever is of this nature, as Fabius Catulinus in the field; Lucius Lupus, and Stertinius, at Baiæ Tiberius at Capreæ and Velius Rufus, and all such examples of vehement prosecution in worldly matters; let these also run in thy mind at the same time; and how vile every object of such earnest and vehement prosecution is; and how much more agreeable to true philosophy it is, for a man to carry himself in every matter that offers itself; justly, and moderately, as one that followeth the Gods with all simplicity. For, for a man to be proud and high conceited, that he is not proud and high conceited, is of all kind of pride and presumption, the most intolerable. XXI. To them that ask thee, Where hast thou seen the Gods, or how knowest thou certainly that there be Gods, that thou art so devout in their worship? I answer first of all, that even to the very eye, they are in some manner visible and apparent. Secondly, neither have I ever seen mine own soul, and yet I respect and honour it. So then for the Gods, by the daily experience that I have of their power and providence towards myself and others, I know certainly that they are, and therefore worship them. XXII. Herein doth consist happiness of life, for a man to know thoroughly the true nature of everything; what is the matter, and what is the form of it: with all his heart and soul, ever to do that which is just, and to speak the truth. What then remaineth but to enjoy thy life in a course and coherence of good actions, one upon another immediately succeeding, and never interrupted, though for never so little a while?
