11. Of each thing ask: What is this in itself and by its constitution? What is its substance or matter? What is its cause? What is its business in the Universe? How long shall it endure?
12. When you are reluctant to be roused from sleep, remember that it accords with your constitution and with human nature to perform social actions. Sleep is common to us with the brutes. Now, whatever accords with the nature of each species must be most proper, most fitting, and most delightful to it.
13. Constantly, and, if possible, on every occasion, apply to your imaginations the methods of Physics, Ethics, and Dialectic.
14. Whomsoever you meet, say straightway to yourself:—What are this man’s principles of good and evil? For if he holds this or that doctrine concerning pleasure and pain, and the causes thereof, concerning glory and infamy, death and life, it will seem to me neither strange nor wondrous that this or that should be his conduct. I shall bear in mind that he has no choice but to act so.
15. Remember that, as ’tis folly to be surprised that a fig-tree bears figs, so is it equal folly to be surprised that the Universe produces those things of which it was ever fruitful. It is folly in a physician to be surprised that a man has fallen into a fever; or in a pilot that the wind has turned against him.
16. Remember that to change your course, and to follow any man who can set you right is no compromise of your freedom. The act is your own, performed on your own impulse and judgment, and according to your own understanding.
17. If the doing of this be in your own power, why do it thus? If it be in another’s, whom do you accuse? The atoms or the Gods? To accuse either is a piece of madness. Therefore accuse no one. Set right, if you can, the cause of error; if you cannot, correct the result at least. If even that be impossible, what purpose can your accusations serve? Nothing should be done without a purpose.
18. That which dies falls not out of the Universe. If then it stays here, here too it suffers a change, and is resolved into those elements of which the world, and you too, consist. These also are changed, and murmur not.
19. The horse, the vine—all things are formed for some purpose. Where is the wonder? Even the sun saith, “I was formed for a certain work;” and similarly the other Gods. For what end are you formed? For pleasure? Look if your soul can endure this thought.
20. Nature has an aim in all things, in the end and surcease of them no less than in their beginning and continuance. It is even as a man casting a ball. Where, then, is the good for the ball in its rising; where the harm in dropping; where even is the harm when it has fallen down? Where is the bubble’s good while it holds together, where is the evil when it is broken? So it is with the lamp which now burns and anon goes out.
