Plato's "Republic"­, Books 6-10

For background information about Plato, recently discussed dialogues (including Books 1-5 of The Republic), and recommended editions of his works, see the meetup announcements for April and May.

The second half of The Republic includes three famous analogies and an assessment of various types of governance. The analogies are the Analogy of the Sun, the Analogy of the Divided Line, and the Allegory of the Cave. Although ostensibly different, the analogies reinforce the same Platonic theme--the world of the senses is illusory, that of the Forms true.

The Allegory of the Cave is a philosophical fable, universally regarded as Plato's most effective. It is set in a dark cave where prisoners look at a wall and see shadows of objects; the shadows represent our imperfect knowledge of the world, gained primarily through the senses. One man breaks away, leaves the cave and enters a world of light. Initially blinded by it, he slowly sees objects as they really are rather than as shadows. The source of the light is the sun, representative of the highest of all Forms, the form of Goodness; it is through Goodness that all true knowledge is obtained. The man returns to the cave and attempts to explain to others what he has seen, but they do not believe him. He exemplifies the philosopher who has attained the highest level of wisdom; to him is given the responsibility of ruling.

The four types of governance Plato critiques are Timocracy, Oligarchy, Democracy, and Tyranny. He explains why he finds each deficient: Timocracy (rule by the military) because it values honor rather than justice; Oligarchy because it privileges the rich at the expense of the poor; Democracy because everyone, regardless of how uninformed they may be, can vote, making them ripe for demagogues; and Tyranny because it can only be maintained by murder, terror, and bribery. Plato’s animus towards Oligarchy and Democracy can be traced in large part to his experience as an Athenian. What is novel about this analysis is that it is psychological as well as historical, the rulers' values a response to poor education or unhealthy parenting.

Plato's psychological theories are foundational in The Republic. He argues that if justice is achieved at a societal level, primarily through class stratification, then harmony at the individual level will follow. His Tripartite Theory of Soul makes the symbiotic relationship explicit: just as social harmony is achieved when people work productively within their social class, so harmony at the individual level is achieved when reason is allowed to regulate biological impulses. A rough symmetry becomes apparent when the two levels are juxtaposed: Guardian=Reason; Soldier=Spirited; Worker=Appetitive. In such an ideal environment citizens act more virtuously, practice more justice, and ultimately achieve what the Greeks believed to be the primary objective of life, Eudaimonia (Happiness).

    I wish to thank the Firehook gang for an exciting and very challenging discussion. I would agree that Zinn’s “People’s History of the United States” is a must read for every American, most of whom have a naïve concept of our virtues. It is a much needed sobering assessment of how greatly we have failed to live up to our ideals, even to the most basic concepts of decency. But as an antidote to this excruciating depiction, I would advocate a re-assessment of our failures in light of the realities of our humanity. To put Zinn’s vision in perspective, I would recommend two very different but exceptional investigations into our human nature and our history. The first is Howard Bloom’s “The Lucifer Principle” which explores just how our worse traits contribute to our successes as much as it does to our failures, and second,

      I think there are two contrasting concepts at work. 1)Winners write history. So histories as described to us is not what really happened. e.g., Bible was a book written by a persecuted people with the environment controlled by the persecutors. 2) How does morality effect history? In all cultures, the books that lasted all give you a positive answer on "Morality". Were they all lying to us or just human wishes?

      The problem is mix these two concepts together. For 1), Bad traits and hardship may have a positive outcome and good traits may have a negative outcome. Abusive environment can toughen you or drive you or kind environment can spoil you. Good can come from bad and vice versa. Old will come from new and old can evolve to be new. For 2), I think we tend to look at morality in terms of individual awards and punishments, instead of looking at society as a whole and in the long term. When a society has people more helping to each other, the society is a happier society. Most people benefits if you look back.

    The first is Howard Bloom’s “The Lucifer Principle” which explores just how our worse traits contribute to our successes as much as it does to our failures, and second, Richard Wright’s “Non-Zero,” which traces historically humanities growing dedication to non-zero rather than zero sum behavior. We are a flawed species, but even so, amazing in our achievements in spice of our flaws.

    Unfortunately, my schedule has shifted at the last minute, and it doesn't look like I'll be able to make it today. I hope you have a great discussion!
