55. Do not look around thee to discover other men’s ruling principles, but look straight to this, to what nature leads thee, both the universal nature through the things which happen to thee, and thy own nature through the acts which must be done by thee. But every being ought to do that which is according to its constitution; and all other things have been constituted for the sake of rational beings, just as among irrational things the inferior for the sake of the superior, but the rational for the sake of one another.

The prime principle then in man’s constitution is the social. And the second is not to yield to the persuasions of the body,—for it is the peculiar office of the rational and intelligent motion to circumscribe itself, and never to be overpowered either by the motion of the senses or of the appetites, for both are animal; but the intelligent motion claims superiority, and does not permit itself to be overpowered by the others. And with good reason, for it is formed by nature to use all of them. The third thing in the rational constitution is freedom from error and from deception. Let then the ruling principle holding fast to these things go straight on, and it has what is its own.

56. Consider thyself to be dead, and to have completed thy life up to the present time; and live according to nature the remainder which is allowed thee.

57. Love that only which happens to thee and is spun with the thread of thy destiny. For what is more suitable?

58. In everything which happens keep before thy eyes those to whom the same things happened, and how they were vexed, and treated them as strange things, and found fault with them: and now where are they? Nowhere. Why then dost thou too choose to act in the same way; and why dost thou not leave these agitations which are foreign to nature to those who cause them and those who are moved by them; and why art thou not altogether intent upon the right way of making use of the things which happen to thee? For then thou wilt use them well, and they will be a material for thee [to work on]. Only attend to thyself, and resolve to be a good man in every act which thou dost: and remember….

59. Look within. Within is the fountain of good, and it will ever bubble up, if thou wilt ever dig.

60. The body ought to be compact, and to show no irregularity either in motion or attitude. For what the mind shows in the face by maintaining in it the expression of intelligence and propriety, that ought to be required also in the whole body. But all these things should be observed without affectation.

61. The art of life is more like the wrestler’s art than the dancer’s, in respect of this, that it should stand ready and firm to meet onsets which are sudden and unexpected.

62. Constantly observe who those are whose approbation thou wishest to have, and what ruling principles they possess. For then thou wilt neither blame those who offend involuntarily, nor wilt thou want their approbation, if thou lookest to the sources of their opinions and appetites.

63. Every soul, the philosopher says, is involuntarily deprived of truth; consequently in the same way it is deprived of justice and temperance and benevolence and everything of the kind. It is most necessary to bear this constantly in mind, for thus thou wilt be more gentle towards all.
