<N.G.L.Hammond, "The Classical Age of Greece" (1975), p.241>

Quote:

Philip was born a Greek of the most aristocratic, indeed of divine, descent… Philip was both a Greek and a Macedonian, even as Demosthenes was a Greek and an Athenian…The Macedonians over whom Philip was to rule were an outlying family member of the Greek-speaking peoples.
