Epictetus says to a certain person who is going to Rome to settle a suit in regards to his Rank/Position to gain Governorship;
"You are not content to stay-at-home with Honors you have,
but you desire something greater and conspicuous
All due to opinions
So did you ever make a Voyage (Inner)
for the purpose of examining your own opinions
and casting them out, if you found they are bad?
whom have you approached for this purpose?
What time you have fixed for examining this?
To go over the times of your life by yourself"
