and if thou shalt strive to live only what is really thy life, that is, the present,—then thou wilt be able to pass that portion of life which remains for thee up to the time of thy death free from perturbations, nobly, and obedient to thy own daemon [to the god that is within thee] (II. 13, 17; III. 5, 6; XI. 12). 4. I have often wondered how it is that every man loves himself more than all the rest of men, but yet sets less value on his own opinion of himself than on the opinion of others. If then a god or a wise teacher should present himself to a man and bid him to think of nothing and to design nothing which he would not express as soon as he conceived it, he could not endure it even for a single day. So much more respect have we to what our neighbors shall think of us than to what we shall think of ourselves. 5. How can it be that the gods, after having arranged all things well and benevolently for mankind, have overlooked this alone, that some men, and very good men, and men who, as we may say, have had most communion with the divinity, and through pious acts and religious observances have been most intimate with the divinity, when they have once died should never exist again, but should be completely extinguished? But if this is so, be assured that if it ought to have been otherwise, the gods would have done it. For if it were just, it would also be possible; and if it were according to nature, nature would have had it so. But because it is not so, if in fact it is not so, be thou convinced that it ought not to have been so: for thou seest even of thyself that in this inquiry thou art disputing with the Deity; and we should not thus dispute with the gods, unless they were most excellent and most just; but if this is so, they would not have allowed anything in the ordering of the universe to be neglected unjustly and irrationally. 6. Practise thyself even in the things which thou despairest of accomplishing. For even the left hand, which is ineffectual for all other things for want of practice, holds the bridle more vigorously than the right hand; for it has been practised in this. 7. Consider in what condition both in body and soul a man should be when he is overtaken by death; and consider the shortness of life, the boundless abyss of time past and future, the feebleness of all matter. 8. Contemplate the formative principles [forms] of things bare of their coverings; the purposes of actions; consider what pain is, what pleasure is, and death, and fame; who is to himself the cause of his uneasiness; how no man is hindered by another; that everything is opinion. 9. In the application of thy principles thou must be like the pancratiast, not like the gladiator; for the gladiator lets fall the sword which he uses and is killed; but the other always has his hand, and needs to do nothing else than use it. 10. See what things are in themselves, dividing them into matter, form, and purpose.
