I am debtor both to Greeks and to Barbarians, both to the wise and to the foolish.

I have a debt to Greeks and to the nations outside; to the wise and to those who have no learning.

Χρεωστης ειμαι προς Ελληνας τε και βαρβαρους, σοφους τε και ασοφους·

I am debtor both to the Greeks, and to the Barbarians; both to the wise, and to the unwise.
