A similar notion is found in Xenophon's Memorabilia by Socrates:
"... to have as few wants as possible is the nearest approach to Godhead; and as that which is divine is mightiest, so that is next mightiest which comes closest to the divine."
The highest aspiration of the sage is arete - best defined as excellence of character in moral virtue. Those who can succeed at focusing and attaining constant moral virtue can be called sages. The sage does not value the "indifferents" in life. Rather he/she values reason and applied social action.
