Plato Today

Introduction: The Modern Condition

The Enlightenment is framed as a movement out of darkness—but who defined the darkness?

Terms like “Renaissance” and “Enlightenment” tell stories about death and rebirth, shadow and light.
This lecture traces Plato’s resurrections across the last 400 years in three core areas:
Mathematics
Myth
Meaning

I. Plato in the Age of the Enlightenment

🔥 The Rise of Materialism

Thomas Hobbes (1588–1679):
Everything is matter, no soul, no telos, no moral order.
Human life in the state of nature is a “war of all against all.”
Only the Leviathan—a powerful state—can restrain our appetites.
Plato already confronted this view in characters like Thrasymachus, Callicles, and Polus.

✨ Resistance: The Cambridge Platonists

Ralph Cudworth and Henry More revived Platonic idealism.
Emphasized inner light and moral order.
Argued that mind ≠ matter; humans can access Truth.

🧠 Rationalists vs Empiricists

Rationalists (e.g., Descartes)	Empiricists (e.g., Hume)
Trust reason over senses	Trust senses over reason
Remnants of Plato’s Sun World	Emphasis on Plato’s Cave World

Plato’s vision integrated both—reason illuminates the shadows of sense.

II. Mathematics: Plato’s Unexpected Resurrection

🏆 Roger Penrose: The Three Worlds

Physical World
Mental World
Mathematical World ← Most controversial

“In order to grasp reality, we must presuppose a Platonic realm of mathematics.” —Penrose

🧮 Mathematics & Reality

Eugene Wigner: The unreasonable effectiveness of mathematics.
Galileo: Nature is written in the language of mathematics.
Newton: Fused physics and math to uncover universal laws.

“There are no perfect circles down here, but how do we even know a circle is imperfect unless we’re comparing it to the Form of a perfect circle?”

III. Language and Logical Platonism

Sentences in different languages—“Snow is white,” “La neige est blanche”—express the same truth.
But truth is not reducible to any single sentence or sound.
Gottlob Frege: Proposes a world of logical thoughts, transcending language.

These truths appear to exist independently of individual minds, hinting at a Platonic realm of thought.

IV. Myth: Plato’s Artistic Soul

📖 Logos and Mythos: Not Enemies

Plato is suspicious of poets like Homer—he sees them as unmoored from Truth.
Yet, Plato is also one of history’s great literary artists.
He uses allegory, myth, and dialogue as tools to lead toward Truth.

🔁 Imitation and Transcendence

In Timaeus, Plato suggests the physical world imitates eternal Forms.
In Phaedrus and Phaedo, beauty in this world stirs longing for true Beauty.
The Allegory of the Cave itself is a myth pointing to higher Truth.

🌠 Myth’s Power to Reveal

Mythos can disclose Logos, not just distract from it.
Allegory, when aligned with truth, becomes a philosophical instrument.

📚 The Literary Legacy

The Faerie Queene (Spenser)
Pilgrim’s Progress (Bunyan)
The Tempest (Shakespeare)

Allegory thrived in the West under the Platonic worldview. Its decline parallels modernity’s disenchantment.

V. C.S. Lewis: Christian Platonism

“There is a real connection between what Plato and the mythmakers most deeply meant and what I believe to be the truth.” —C.S. Lewis

Lewis’s Narnia is a myth that points to a truer reality beyond.
The Last Battle ends with:

“It’s all in Plato. Bless me! What do they teach them at these schools?”

VI. Meaning: Not Yours to Make

🧭 Meaning as Alignment with Reality

Modern talk: “That’s your truth.” / “That’s my meaning.”
Plato’s view: Truth is singular. Meaning is fixed.
Like math: 2+2=4 doesn’t depend on your preference.

🪞 Objective Meaning vs Subjective Storytelling

A watch has no objective monetary value—but in relationship, it gains real meaning (e.g., a family heirloom).
Subjective value is real when grounded in objective goods (love, memory, sacrifice).
Arbitrary ascriptions of meaning are false.

VII. The Political Implication

Democracy, for Plato, devolves into ochlocracy (mob rule) and then tyranny.
Why? Because in placing freedom and equality above all, society loses its anchor to objective meaning and Goodness.
True freedom requires limits, laws, and hierarchy based in Truth.

VIII. Final Reflections

“Heaven is more real than the earth.” – Plato through Lewis

The world we live in is a shadow, but not a lie.
The task of the philosopher is to discern the signal of transcendence within the noise.
The journey out of the cave is lifelong, requiring both reason and imagination.

🔄 Summary of Plato’s Modern Resurrections

Category	Modern Example	Platonic Echo
Mathematics	Penrose, Wigner, Physics	Eternal Forms and Geometries
Language	Frege, Logical Truths	Realm of unchanging thoughts
Myth	C.S. Lewis, Allegory	Art that leads to the Good
Meaning	Critique of Relativism	Fixed essence, truth, purpose

❓ Reflective Questions

Are you crafting meaning, or aligning with it?
Is your imagination guided by the Logos or detached from it?
Do you use story to deepen truth or escape from it?
Have you begun the journey out of the cave?

“In this school, the Peterson Academy, Plato has been taught.”
Let that be only the beginning of your journey into the Sunlight.
