It is impossible for a man to begin to learn what he thinks he knows.

Epictetus (c.55-c.135) Greek (Phrygian) Stoic philosopher
Discourses, 2.17 [tr. Long (1890)]

What is the first business of one who studies philosophy? To part with self-conceit. For it is impossible for any one to begin to learn what he thinks that he already knows.

Epictetus (c.55-c.135) Greek (Phrygian) Stoic philosopher
Discourses, ch. xvii, “How To Apply General Principles to Particular Cases”

First say to yourself what you would be; and then do what you have to do.

Epictetus (c.55-c.135) Greek (Phrygian) Stoic philosopher
Discourses, ch. xxiii, “Concerning Such as Read and Dispute Ostentatiously”

Men are disturbed, not by things, but by the principles and notions which they form concerning things

Epictetus (c.55-c.135) Greek (Phrygian) Stoic philosopher
The Enchiridion (c. 135)

These reasonings are unconnected: “I am richer than you, therefore I am better”; “I am more eloquent than you, therefore I am better.” The connection is rather this: “I am richer than you, therefore my property is greater than yours;” “I am more eloquent than you, therefore my style is better than yours.” But you, after all, are neither property nor style.

Epictetus (c.55-c.135) Greek (Phrygian) Stoic philosopher
The Enchiridion (c. 135)

Choose the best life; for habit will make it pleasant.
