Teacher looks for: Correct identification of Book 1’s speakers, arguments, and unresolved debate
How to meet it: Cross-reference your notes with a trusted, student-focused summary to confirm key details about each character’s position
Teacher looks for: Ability to link arguments to character traits or text structure, not just summarize content
How to meet it: Write one sentence for each argument explaining how it reflects the speaker’s social role
Teacher looks for: Recognition of logical gaps in presented definitions and the purpose of the unresolved debate

Each speaker in Book 1 represents a different segment of ancient Athenian society. Their ideas about justice are tied to their daily lives and social standing. Write one sentence linking each speaker’s profession to their definition of justice.
Socrates does not lecture or state his own beliefs in Book 1. Instead, he asks targeted questions to expose logical gaps in other people’s arguments. Practice this method by asking a peer to defend a modern idea of justice, then pointing out one logical gap in their reasoning.
Book 1 ends without a clear definition of justice. This forces readers to continue thinking about the question, rather than accepting a simple answer. Write a 3-sentence explanation of how this unresolved ending serves Plato’s overall goal in the Republic.
The debates in Book 1 set up the entire rest of the Republic’s inquiry into justice. Plato uses the flaws exposed in Book 1 to build a more complex, structured argument about justice in later books. Create a 2-column chart linking Book 1’s unresolved questions to the topics you expect to see in later books.
Many of the definitions of justice in Book 1 mirror ideas people still use today, such as justice as following laws or paying debts. Pick one definition from Book 1 and find a modern news story that reflects that same idea. Write a 2-sentence link between the story and the Book 1 argument.
The most common mistake on Book 1 exams is claiming Socrates states his own definition of justice. He does not — his role is to challenge others’ ideas. Quiz yourself on the exam kit’s common mistakes to ensure you don’t make these errors on your next test.
The main question of Book 1 is: What is justice, and does it benefit the person who practices it? No single answer is agreed upon by the end of the book.
The main characters are Socrates and several Athenian men of different social roles, including a wealthy merchant, a retired soldier, and a sophist. Each presents a different definition of justice.
No, Book 1 ends without a single, agreed-upon definition of justice. The debate is unresolved, which sets up the rest of the Republic’s inquiry into the topic.
Book 1 exposes the flaws in common, surface-level definitions of justice. This creates a need for a deeper, more structured inquiry into justice, which is the focus of the remaining books.
