    Examines Socrates as Plato's primary influence, including the elenctic method and moral focus. Distinguishes the historical Socrates from Plato's literary character.

  • Lesson 3 • Plato's Life and Historical Context

    Covers Plato's biography, Athens in the 5th–4th centuries BCE, and key political events shaping his thought. Grounds all later doctrine in lived historical reality.

Chapter 2See details

Epistemology and the Theory of Knowledge

  • Lesson 1 • Knowledge, Virtue, and the Good

    Connects Plato's epistemology to his ethics through the Form of the Good. Students see how knowing the Good is prerequisite to virtuous action.

  • Lesson 2 • Critiques and Limits of Platonic Epistemology

    Surveys ancient and modern objections to Plato's theory of knowledge. Students develop critical distance and evaluate the theory's strengths and weaknesses.

  • Lesson 3 • The Allegory of the Cave

    Interprets the Cave allegory as an epistemological and political narrative. Students trace the philosopher's ascent from illusion to understanding.

  • Lesson 4 • Opinion, Belief, and True Knowledge

  • Lesson 5 • The Divided Line and Levels of Reality

    Analyzes the Divided Line analogy from the Republic, mapping cognitive states to ontological levels. Students connect epistemology directly to Plato's metaphysics.

Chapter 3See details

Metaphysics and the Theory of Forms

  • Lesson 1 • Forms in Ethics and Aesthetics

    Applies the Theory of Forms to moral and aesthetic judgment using the Symposium and Phaedrus. Students connect abstract metaphysics to practical evaluation.

  • Lesson 2 • The Third Man Argument and Self-Criticism

    Analyzes Plato's own critique in the Parmenides, including the Third Man regress. Students see Plato as a self-critical thinker who refines his own theory.

  • Lesson 3 • Introduction to the Theory of Forms

    Presents the basic claim that abstract Forms are more real than physical particulars. Draws on the Phaedo, Republic, and Symposium for initial evidence.

  • Lesson 4 • Participation and the Relationship Between Forms and Particulars

    Explores how physical things 'participate' in Forms and the philosophical problems this raises. Prepares students for the Third Man Argument critique.

  • Lesson 5 • Arguments for the Existence of Forms

    Examines the Argument from Relativity, One Over Many, and the Argument from Knowledge. Students assess the logical force of each argument independently.

Chapter 4See details

Philosophy of the Soul and Immortality

  • Lesson 1 • Objections and Philosophical Assessment

    Surveys Simmias's harmony objection and Cebes's weaving objection from the Phaedo. Students practice philosophical rebuttal and assess Plato's responses.

  • Lesson 2 • Arguments for Immortality in the Phaedo

    Examines the Cyclical, Recollection, Affinity, and Final arguments for the soul's immortality. Students evaluate the logical structure of each argument.

  • Lesson 3 • What Is the Soul for Plato?

  • Lesson 5 • The Phaedrus Myth and the Winged Soul

    Analyzes the charioteer myth as a model of the soul's structure and its cosmic journey. Students connect this myth to the tripartite soul and eros.

Chapter 5See details

Ethics and the Virtuous Soul

  • Lesson 1 • The Cardinal Virtues

    Analyzes wisdom, courage, moderation, and justice as Plato defines them. Students trace how each virtue corresponds to a part of the soul and city.

  • Lesson 2 • Virtue, Happiness, and the Good Life

    Connects virtue to eudaimonia (flourishing) and argues that justice is intrinsically good. Students evaluate Plato's response to the challenge of Thrasymachus.

  • Lesson 3 • The Tripartite Soul

    Introduces the rational, spirited, and appetitive parts of the soul from the Republic. Students map each part to corresponding virtues and social classes.

  • Lesson 4 • Weakness of Will and Moral Failure

    Investigates Plato's denial of akrasia (weakness of will) and his intellectualist account of wrongdoing. Students compare this to Aristotle's competing view.

  • Lesson 5 • Eros, Love, and Moral Ascent

    Examines the Symposium's ladder of love as a path from physical desire to philosophical wisdom. Students see eros as a moral and epistemological force.

Chapter 6See details

Political Philosophy and the Ideal State

  • Lesson 1 • The Laws and Practical Governance

    Introduces the Laws as Plato's more realistic political vision, emphasizing rule of law over philosopher-kings. Students compare it to the Republic's ideal.

    Examines the argument that only philosophers are fit to rule, grounded in their knowledge of the Good. Students assess the feasibility and dangers of this claim.

  • Lesson 3 • Degenerate Constitutions

    Traces the decline from aristocracy through timocracy, oligarchy, democracy, and tyranny. Students apply this typology to analyze political change.

  • Lesson 4 • The City-Soul Analogy

    Establishes the parallel between the just soul and the just city as the Republic's organizing framework. Students use this analogy to interpret political arguments.

  • Lesson 5 • Education, Censorship, and the Noble Lie

Chapter 7See details

Aesthetics, Art, and Imitation

    Surveys later reinterpretations of Platonic aesthetics, including Neoplatonist and Renaissance readings. Students evaluate Plato's lasting influence on art theory.

  • Lesson 4 • The Expulsion of the Poets

  • Lesson 5 • Beauty, Eros, and Philosophical Ascent

    Revisits the Symposium and Phaedrus to show beauty as a legitimate path toward the Forms. Students see Plato's positive aesthetic alongside his critique.

Chapter 8See details

  • Lesson 3 • The Timaeus and Cosmology

    Introduces the Timaeus's account of the Demiurge, the World Soul, and the creation of the cosmos. Students connect cosmology to the Theory of Forms.
