In Book V of Plato’s Laws, only the unnamed Athenian speaks while the other two characters, Clinias from Crete and Megillus from Sparta, listen to his presentation on the power of the soul, harmony in human behaviour, and the just division of property for Crete’s new colony to be called Magnesia. On May 12, 2024, Plato’s Pod held its eighth meeting on Plato’s longest and last dialogue, with members of the Toronto, Calgary, and Chicago Philosophy Meetup groups participating. We began by listening to the Athenian’s compelling exposition on the nature of the soul as the master in us, with the body as its slave. The Athenian continues by explaining how the virtuous soul gains happiness by moderating pains and pleasures, and his proposition that the new community should be “purged” of those who cause disharmony provoked a discussion among the participants on questions of ethics and the distinction between religious and secular ethics and laws. Book V ends with the Athenian’s famous and curious proposal that 5,040 is the ideal population of a community. What did Plato, who sprinkled mathematics and geometry throughout his dialogues, intend to convey with this number?
