① Who is speaking: Plato's dialogues and Socrates

Chapter 3, Section “Plato's dialogues: who is speaking?” · Session 1, Segment 1, “Plato's dialogues and Socrates as their speaker” · Remember: Plato is the author, Socrates is usually the speaker, and the course credits the theory of Forms to Plato.

Plato, section 7: Socrates as the dominant speaker — online Encyclopedia of Philosophy (reference entry) — a reference entry's section on why Socrates leads so many of Plato's dialogues, and on why that makes it hard to say which views are Plato's own; read section 7 only and skip the rest of the entry. (reading, 6–10 min)
What is the Difference Between Early, Middle, and Late Plato? — Carneades.org — an explainer on the traditional sorting of the dialogues into early, middle, and late groups, with the early ones read as closer to the historical Socrates and the middle ones, where the Forms appear, as more Plato's own; it then gives reasons to doubt that neat story. The lists of dialogue titles go beyond this week, and the automatic captions misspell several names. (video, 10 min) (captions: automatic)

② Shadows on the wall: the allegory of the cave

Chapter 3, Section “The allegory of the cave: shadows on the wall” · Session 1, Segment 2, “The allegory of the cave” · Remember: the cave is an allegory, so the shadows stand for what we perceive and the freed prisoner stands for the philosopher.

Allegory of the cave, Summary — Wikipedia — an encyclopedia's step-by-step summary of the story: the prisoners facing the wall, the fire behind them, the freed prisoner's slow climb into the sunlight, and his return to the den. Read the Summary section only and skip the later sections on scholarship and influence. (reading, 3–5 min)
Leonardo DiCaprio & The Nature of Reality: Crash Course Philosophy #4 — CrashCourse — a lively episode that sets the cave beside a film about layered dreams, retells the prisoners, the shadows, and the escape, and explains why the returning prisoner's friends think his journey harmed him. It calls the story a myth; the chapter calls it an allegory. The closing puzzle about a cat with three tails goes beyond this week. (video, 9 min) (captions: creator)
Plato's Allegory of the Cave — Philosophy Vibe — an animated retelling that adds the echoes in the cave and the prisoners' contests over guessing which shadow comes next, then reads the escaped prisoner as the philosopher. It casts the people carrying the objects as rulers of the cave; treat that as the video's own retelling. Use it while working through the Week-3 module overview. (video, 6 min) (captions: automatic)

③ Forms, what they explain, and the objections

Chapter 3, Section “Testing the theory: three objections and three replies” · Session 2, Segment 3, “The theory of Forms and its objections” · Remember: state the theory in its strongest form first, then test it with the access, participation, and regress objections.

Plato, section 6.b: The Theory of Forms — Internet Encyclopedia of Philosophy — a reference article's section on the theory of Forms in the middle dialogues: Forms as unchanging realities that sensible things share in, and as perfect standards against which a knower judges how closely things come to them. Read section 6.b only. (reading, 6–10 min)
Plato's Theory of Forms — Philosophy Vibe — a two-voice debate that recaps the cave, explains a Form with two different cats and two different chairs, and closes with objections: no one experiences the Forms, a Form of trivial or evil things seems strange, and little is said about what a Form is like. Its ladder of Forms and its reading of the sun as the Form of the Good go beyond this week; treat them as the video's own account. This builds on Week 2's work with reading an argument charitably before criticizing it. (video, 10 min) (captions: automatic)
Plato's Theory of Forms — Feeling Philosophical — a short explainer that sets the theory of Forms against the everyday view that we see things exactly as they are, asks whether we can perceive the Forms, and ends with criticisms, including an endless-regress argument that matches the chapter's regress objection. It credits that argument to Aristotle; the chapter names no source for it, so treat the credit as the video's own. (video, 7 min) (captions: automatic)

④ Glaucon's ring: a story set aside for now

Chapter 3, Section “The ring of Gyges: Glaucon's challenge, set aside for now” · Session 2, Segment 4, “The ring of Gyges, introduced” · Remember: Glaucon tells the ring story in Book II as a challenge to Socrates, not as Socrates' own argument.

The Ring of Gyges Explained — Matt Benjamin — a short explainer that places the ring story inside the Republic's question of whether justice or injustice is better, and points out that Glaucon, not Socrates, tells it. Watch it for where the story sits and who tells it; the debate over whether the person who acts justly is happier goes beyond this week. The automatic captions misspell the name Gyges. (video, 5 min) (captions: automatic)

Optional one-stop reference (free online reference)

The Republic, Book VII (trans. Benjamin Jowett) — The Internet Classics Archive — the primary text of Book VII in Jowett's public-domain English, which opens with the allegory of the cave; read from the opening through the freed prisoner's return to the den, and remember that the English words are Jowett's. Stop there; next week turns to Descartes' doubt and the debate between rationalism and empiricism. (reading, 15–20 min)
