Quotes from the book Enchiridion, by Epictetus

Philosophy as a way of life makes men free. It is the last ditch stand of liberty in a world of servitude. This knowledge of ourselves makes us free in a world of dependencies.

You must watch, you must labor, you must get the better of certain appetites, must quit your acquaintances, be despised by your servant, be laughed at by those you meet; come off worse than others in everything—in offices, in honors, before tribunals. When you have fully considered all these things, approach, if you please—that is, if, by parting with them, you have a mind to purchase serenity, freedom, and tranquillity. If not, do not come hither; do not, like children, be now a philosopher, then a publican, then an orator, and then one of Caesar’s officers. These things are not consistent. You must be one man, either good or bad. You must cultivate either your own reason or else externals; apply yourself either to things within or without you—that is, be either a philosopher or one of the mob.

For sheep do not hastily throw up the grass to show the shepherds how much they have eaten, but, inwardly digesting their food, they produce it outwardly in wool and milk.

Upon every accident, remember to turn toward yourself and inquire what faculty you have for its use. If you encounter a handsome person, you will find continence the faculty needed; if pain, then fortitude; if reviling, then patience. And when thus habituated, the phenomena of existence will not overwhelm you.

While he permits you to possess it, hold it as something not your own, as do travelers at an inn. and though you should appear to others to be somebody, distrust yourself.

The condition and characteristic of a vulgar person is that he never looks for either help or harm from himself, but only from externals. The condition and characteristic of a philosopher is that he looks to himself for all help or harm. The marks of a proficient are that he censures no one, praises no one, blames no one, accuses no one; says nothing concerning himself as being anybody or knowing anything. When he is in any instance hindered or restrained, he accuses himself; and if he is praised, he smiles to himself at the person who praises him; and if he is censured, he makes no defense. But he goes about with the caution of a convalescent, careful of interference with anything that is doing well but not yet quite secure. He restrains desire; he transfers his aversion to those things only which thwart the proper use of our own will; he employs his energies moderately in all directions; if he appears stupid or ignorant, he does not care; and, in a word, he keeps watch over himself as over an enemy and one in ambush.

Whatever rules you have adopted, abide by them as laws, and as if you would be impious to transgress them; and do not regard what anyone says of you, for this, after all, is no concern of yours. How long, then, will you delay to demand of yourself the noblest improvements, and in no instance to transgress the judgments of reason? You have received the philosophic principles with which you ought to be conversant; you have been conversant with them. For what other masters, then, do you wait as an excuse for this delay in self-reformation? You are no longer a boy but a grown man. If therefore, you will be negligent and slothful, and always add procrastination to procrastination, purpose to purpose, and fix day after day in which you will attend to yourself, you will insensibly continue to accomplish nothing and, living and dying, remain of a vulgar mind.

This instant, then, think yourself worthy of living as a man grown up and a proficient. Let whatever appears to be the best be to you an inviolable law. And if any instance of pain or pleasure, glory or disgrace, be set before you, remember that now is the combat, now the Olympiad comes on, nor can it be put off; and that by one failure and defeat honor may be lost or—won. Thus Socrates became perfect, improving himself by everything, following reason alone. And though you are not yet a Socrates, you ought, however, to live as one seeking to be a Socrates.
