Epictetus, Golden Sayings 121

A Philosopher's school is a Surgery: pain, not pleasure, you should have felt therein. For on entering none of you is whole. 

One has a shoulder out of joint, another an abscess. A third suffers from an issue, a fourth from pains in the head. 

And am I then to sit down and treat you to pretty sentiments and empty flourishes, so that you may applaud me and depart, with neither shoulder, nor head, nor issue, nor abscess a whit the better for your visit? 

Is it then for this that young men are to quit their homes, and leave parents, friends, kinsmen and substance to mouth out "Bravo!" to your empty phrases?
