From: The Golden Sayings of Epictetus (translated by Hastings Crossley) - from Project Gutenberg.
—"O! when shall I see Athens and its Acropolis again?"—Miserable man! art thou not contented with the daily sights that meet thine eyes? canst thou behold aught greater or nobler than the Sun, Moon, and Stars; than the outspread Earth and Sea?

When thou art about to bid farewell to the Sun and Moon itself, wilt thou sit down and cry like a child? Why, what didst thou hear, what didst thou learn? why didst thou write thyself down a philosopher, when thou mightest have written what was the fact, namely, "I have made one or two Compendiums, I have read some works of Chrysippus, and I have not even touched the hem of Philosophy's robe!"
