In part 3, we move to Book IV of the Republic where Socrates, Glaucon and Adeimantus both represent and discuss the tripartite caste system of the kallipolis, and the 3 parts of the soul. Covered here is the origins of eugenics among the Greeks, the ideal state, the Oracle at Delphi and the Appollonian mysteries as the center of theology for the Republic (and why that is). I also cover the historical parallels and influences of the Republic and its theories in Book IV in history, including the French Revolution, Marxism, Malthus, Galton and Huxley.
