A man should always have these two rules in readiness; the one, to do only whatever the reason of the ruling and legislating faculty may suggest for the use of men; the other, to change thy opinion, if there is any one at hand who sets thee right and moves thee from any opinion. But this change of opinion must proceed only from a certain persuasion, as of what is just or of common advantage, and the like, not because it appears pleasant or brings reputation.
The ruling faculty does not disturb itself; I mean, does not frighten itself or cause itself pain. But if any one else can frighten or pain it, let him do so. For the faculty itself will not by its own opinion turn itself into such ways. Let the body itself take care, if it can, that is suffer nothing, and let it speak, if it suffers. But the soul itself, that which is subject to fear, to pain, which has completely the power of forming an opinion about these things, will suffer nothing, for it will never deviate into such a judgement. The leading principle in itself wants nothing, unless it makes a want for itself; and therefore it is both free from perturbation and unimpeded, if it does not disturb and impede itself.
It is peculiar to man to love even those who do wrong. And this happens, if when they do wrong it occurs to thee that they are kinsmen, and that they do wrong through ignorance and unintentionally, and that soon both of you will die; and above all, that the wrong-doer has done thee no harm, for he has not made thy ruling faculty worse than it was before.
About pain: The pain which is intolerable carries us off; but that which lasts a long time is tolerable; and the mind maintains its own tranquility by retiring into itself, and the ruling faculty is not made worse. But the parts which are harmed by pain, let them, if they can, give their opinion about it.
Different things delight different people. But it is my delight to keep the ruling faculty sound without turning away either from any man or from any of the things which happen to men, but looking at and receiving all with welcome eyes and using everything according to its value.
Remember that the ruling faculty is invincible, when self-collected it is satisfied with itself, if it does nothing which it does not choose to do, even if it resist from mere obstinacy. What then will it be when it forms a judgement about anything aided by reason and deliberately? Therefore the mind which is free from passions is a citadel, for man has nothing more secure to which he can fly for, refuge and for the future be inexpugnable. He then who has not seen this is an ignorant man; but he who has seen it and does not fly to this refuge is unhappy.
Enter into every man's ruling faculty; and also let every other man enter into thine.
Wipe out imagination: check desire: extinguish appetite: keep the ruling faculty in its own power.
Things stand outside of us, themselves by themselves, neither knowing aught of themselves, nor expressing any judgement. What is it, then, which does judge about them? The ruling faculty.
Hasten to examine thy own ruling faculty and that of the universe and that of thy neighbour: thy own that thou mayest make it just: and that of the universe, that thou mayest remember of what thou art a part; and that of thy neighbour, that thou mayest know whether he has acted ignorantly or with knowledge, and that thou mayest also consider that his ruling faculty is akin to thine.
Thou hast endured infinite troubles through not being contented with thy ruling faculty, when it does the things which it is constituted by nature to do. But enough of this.
Either all things proceed from one intelligent source and come together as in one body, and the part ought not to find fault with what is done for the benefit of the whole; or there are only atoms, and nothing else than mixture and dispersion. Why, then, art thou disturbed? Say to the ruling faculty, Art thou dead, art thou corrupted, art thou playing the hypocrite, art thou become a beast, dost thou herd and feed with the rest?
What is my ruling faculty now to me? And of what nature am I now making it? And for what purpose am I now using it? Is it void of understanding? Is it loosed and rent asunder from social life? Is it melted into and mixed with the poor flesh so as to move together with it?
