Consider, for example, and you will find that almost all the transactions in the time of Vespasian differed little from those of the present day. You there find marrying and giving in marriage, educating children, sickness, death, war, joyous holidays, traffic, agriculture, flatterers, insolent pride, suspicions, laying of plots, longing for the death of others, newsmongers, lovers, misers, men canvassing for the consulship and for the kingdom; yet all these passed away, and are nowhere.
Put it out of the power of truth to give you an ill character; and, if anybody reports you not to be an honest man, let your practice give him the lie; and to make all sure, you should resolve to live no longer than you can live honestly; for it is better to be nothing than a knave.
Such as are thy habitual thoughts, such also will be the character of thy mind; for the soul is dyed by the thoughts. Dye it then with a continuous series of such thoughts as these: that where a man can live, there he can also live well.
