Let actions show philosophy
Principle 46 from the Enchiridion
Practice first and let the result appear in ordinary behavior. An idea becomes convincing when it changes how you act, not when you explain it well.
Original Passage
Never call yourself a philosopher, nor talk a great deal among the unlearned about theorems, but act conformably to them. Thus, at an entertainment, don't talk how persons ought to eat, but eat as you ought. For remember that in this manner Socrates also universally avoided all ostentation. And when persons came to him and desired to be recommended by him to philosophers, he took and recommended them, so well did he bear being overlooked. So that if ever any talk should happen among the unlearned concerning philosophic theorems, be you, for the most part, silent. For there is great danger in immediately throwing out what you have not digested. And, if anyone tells you that you know nothing, and you are not nettled at it, then you may be sure that you have begun your business. For sheep don't throw up the grass to show the shepherds how much they have eaten; but, inwardly digesting their food, they outwardly produce wool and milk. Thus, therefore, do you likewise not show theorems to the unlearned, but the actions produced by them after they have been digested.
Modern Interpretation
Epictetus warns how easily philosophy can become a performance. Talking about a wise life is much easier than living one.
He uses the image of digestion: take in the teaching, practice it, and let the result appear in your behavior. Until then, knowledge can remain little more than a collection of impressive words.
In Practice
You read a lot about discipline and give good advice, but still react impulsively under stress.
Give fewer speeches and choose one thing to practice, such as pausing before an angry reply. Let the behavior carry the lesson.
Reflection Question
What advice is easy for you to give other people but hard to follow yourself?
