16. Within ten days, if you return to the observance of moral principles and to the cult of reason, you will appear a God to them who now esteem you a wild beast or an ape. 17. Order not your life as though you had ten thousand years to live. Fate hangs over you. While you live, while yet you may, be good. 18. How much he gains in leisure who looks not to what his neighbours say, or do, or intend; but considers only how his own actions may be just and holy, looking not, as Agathon says, to the moral example of others, but running a straight course and never turning therefrom. 19. He who is careful and troubled about the fame which is to live after him considers not that each one of those who remember him must very soon die himself, and thereafter also the succeeding generation, until every memory of him, handed on by excited and ephemeral admirers, dies utterly away. Grant that your memory were immortal, and those immortal who retain it; yet what is that to you? I ask not, what is that to the dead? But to the living what is the profit in praise, except it be in some convenience that it brings? And you now abandon what nature has put in your power in order to set your hopes upon the report of others. 20. Whatever is beautiful at all is beautiful in itself. Its beauty ends there, and praise has no part in it. Nothing is the better or the worse for being praised; and this holds also of what is beautiful in the common estimation: of material forms and works of art. Thus true beauty needs nothing beyond itself, any more than law, or truth, or kindness, or honour. For none of these gets a single grace from praise or one blot from censure. Does the emerald lose its virtue if one praise it not? Can one by scanting praise depreciate gold, ivory, or purple, a lyre or a dagger, a flower or a shrub? 21. If our souls survive us, how, you ask, has the air contained them from eternity? How, I answer, does the earth contain so many bodies buried during so long a time? Just as corpses, after remaining for a while in the earth, change, and are dissipated to make room for others; so also the souls, liberated into air, remain for a little, and then are changed, diffused, rekindled, and resumed into the universal productive spirit; and so give way to others who come to take their places. This may serve for an answer, on the supposition that the soul survives the body. But we have not merely to consider the number of bodies thus buried in the earth. There are also all the living creatures eaten day by day by ourselves and other animals. How great a multitude of them is thus consumed, and as it were buried in the bodies of those who feed upon them. Yet there is ever space to contain them, owing to the changes into blood, air, and fire. What, then, is the key to this enquiry? Discrimination of matter and cause. 22. Swerve not from your path. In every impulse render justice its due, and in all thinking be sure that you understand.
