Therefore, since the others are so lacking in spirit, I think it is opportune for you to head the war against the King; and, while it is only natural for the other descendants of Heracles, and for men who are under the bonds of their polities and laws, to cleave fondly to that state in which they happen to dwell, it is your privilege, as one who has been blessed with untrammeled freedom, to consider all Hellas (Greece) your fatherland, as did the founder of your race, and to be as ready to brave perils for her sake as for the things about which you are personally most concerned.

To Philip, 5.127 (Loeb).
