Republic: When Philosophers are Kings

Why Philosophers?

Recall: Philosophers, lovers wisdom, who want knowledge, a connection with what really is what it is, not what is only partly or imperfectly what is.

Now that we've got a definition, why let them rule?

Three Main Arguments

  1. From traits: essentially, Philosophers will have many good qualities as a result of their relationship to truth.
  1. Against the mob.
  1. Mending the world:

    those who are verily and indeed wanting in the knowledge of the true being of each thing... [who] are unable as with a painters eye to look at the absolute truth and to that original to repair... and order the laws about beauty, goodness, justice... are not such persons, I ask, simply blind?

On the Argument from Traits

  • A noble nature most easily corrupted: Alcibiades

  • Evil and Greatnesss: "this being the class out of which comes the men who are the authors of the greatest evil to the state... and also the greatest good"

The Ship of State

The captain of the mutiny?

Or the pilot?

The Mob

imagine a man who should study the tempers of a mighty strong beast, which is fed by him... When, by continually attending upon [it] he has become perfect in [predicting its cries and groans] he calls this honourable and that dishonourable, or good and evil... all in accordance with the tastes and tempers of that great beast.

The Highest Knowledge

Why does the knowledge of the guardians qualify them for rule, and make them analogous to the pilot? They're not technical experts, like the cobbler or the shipbuilder.

What, in more detail, is the sort of thing that the guardians will know?

The Good

That without which, any other knowledge or possession of any kind will profit us nothing.

What is the good?

  1. Not pleasures, since there are bad pleasures and good.
  2. Not knowledge, since it's only valuable (good) pieces of knowledge that's are worth having.

Defining the Good

By Analogy.

The many, as we say, are seen but not known, and the ideas are known but not seen

Not literal sight---that's the analogy

Without the addition of some other nature, there is no seeing or being seen

The Analogy to Light

The sun (the child of the good) is to the faculty of sight, as the good is to the faculty of knowledge

when resting upon that on which truth and being shine, the soul perceives and understands, and is radiant with intelligence; but when turned towards the twilight of becoming and perishing, then she has opinion only, and goes blinking about, and is first of one opinion and then of another

The Divided Line

Reflections - The Reflected - The Hypothetical - First Principles

Geometry

In Geometry

there are their hypotheses, which they and everyone else are supposed to know, and they do not deign to give any account of them either to themselves or others... but they begin with them, and go on until they arrive, at last, and in a consistent manner, at their conclusion

Dialectic

using hypotheses not as first principles, but only as hypotheses---that is to say, steps and points of departure into a world above hypotheses... the first principles of the whole.
