Laws - Plato - Translated with an introduction by Benjamin Jowett The Laws is Plato's last and longest dialogue. The conversation depicted in the work's twelve books begins with the question of who is given the credit for establishing a civilization's laws. Its musings on the ethics of government and law have established it as a classic of political philosophy alongside Plato's more widely read Republic. The genuineness of the Laws is sufficiently proved (1) by more than twenty citations of them in the writings of Aristotle, who was residing at Athens during the last twenty years of the life of Plato, and who, having left it after his death (B.C. 347), returned thither twelve years later (B.C. 335); (2) by the allusion of Isocrates (Oratio ad Philippum missa, p.84: To men tais paneguresin enochlein kai pros apantas legein tous sunprechontas en autais pros oudena legein estin, all omoios oi toioutoi ton logon (sc. speeches in the assembly) akuroi tugchanousin ontes tois nomois kai tais politeiais tais upo ton sophiston gegrammenais.) - writing 346 B.C., a year after the death of Plato, and probably not more than three or four years after the composition of the Laws - who speaks of the Laws and Republics written by philosophers (upo ton sophiston); (3) by the reference (Athen.) of the comic poet Alexis, a younger contemporary of Plato (fl. B.C 356-306), to the enactment about prices, which occurs in Laws xi., viz that the same goods should not be offered at two prices on the same day
