“On no occasion call yourself a philosopher, and do not, for the most part, talk among laymen about your philosophic principles, but do what follows from your principles. For example, at a banquet do not say how people ought to eat, but eat as a man ought. For remember how Socrates had so completely eliminated the thought of ostentation, that people came to him when they wanted him to introduce them to philosophers, and he used to bring them along. So well did he submit to being overlooked. And if talk about some philosophic principle arises among laymen, keep silence for the most part, for there is great danger that you will spew up immediately what you have not digested. So when a man tells you that you know nothing, and you, like Socrates, are not hurt, then rest assured that you are making a beginning with the business you have undertaken. For sheep, too, do not bring their fodder to the shepherds and show how much they have eaten, but they digest their food within them, and on the outside produce wool and milk. And so do you, therefore, make no display to the laymen of your philosophical principles, but let them see the results which come from these principles when digested.” – The Enchiridion of Epictetus, Chapter 46

Meaning: Stoicism is not about demonstrating what you know through talking about it. It’s about demonstrating through the way you live your life, having understood the principles and put them into action.
