In this bibliography “Greek and Roman political philosophy” is taken to mean philosophical reflection on politics in the Greco-Roman world from the 5th century bce to the 5th century ce. More particularly, ancient political philosophy involves reflection on the establishment of political institutions and laws; the nature of political rule; central social and political concepts such as liberty, justice, and equality; the rights and duties of citizenship and its relationship to a flourishing human life; civic education; and the different possible forms of constitutions or regimes. Scholars frequently distinguish political philosophy from political thought. Political thought encompasses any thinking about politics at all and may be expressed through a wide range of media and literary forms, from epistles to comedy to inscriptions. Political philosophy represents thinking about politics that is more specifically theoretical and systematic in nature. Thus, political philosophy may be seen as a subset of political thought. Because this bibliography is concerned with the narrower of the two categories, it focuses primarily on philosophers and theoretical discourse. This focus also informs the general organization of this entry, which adopts a chronological, author-by-author approach rather than the thematic approach sometimes utilized by historians of political thought. This bibliography covers Early Greek, Athenian, Hellenistic, Roman, and Early Christian political philosophy, extending from the Presocratics to St. Augustine.
