Themes in this chapter

  • Virtue as the Only Good

    The excerpt implies justice, a key virtue, is inherently complete and self-validating, needing nothing external to justify or define it.

Key passages

  • “As that which is straight does not need that which is straight, so neither does the just need that which is just.”

    A straight line is defined by its own nature and doesn't require another straight line to prove it is straight. In the same way, a just person or action is inherently just and does not require an external standard or another just thing to validate it.

    This uses a geometric analogy to argue for the intrinsic and self-sufficient nature of virtue, specifically justice.
