In which a philosopher who travelled with Alexander discovers that the wisest response to any claim might be: "I withhold judgement"
♦ ♦ ♦What do you remember from Epicureanism and the Stoic response?
The Stoic promises mastery. The Epicurean promises simple pleasure. What does Skepticism promise?
We have travelled far. The Milesians asked what is everything made of? Plato said, retreat to eternal forms. Aristotle said, reason about essences. The Stoics said, control your judgments. But now we face a deeper problem: Can we ever be certain of anything? If every argument has an equally strong counter-argument, how can we know anything at all? And if we cannot know, should we keep believing? Or should we do something more radical: suspend belief entirely?
Pyrrho was born in Elis, in the Peloponnese. He became a painter, then a philosopher. At some point, he joined Alexander the Great's expedition to India—perhaps as a teacher, perhaps simply as a companion seeking wisdom.
In India, Pyrrho encountered the gymnosophists—wandering ascetic philosophers, some of them naked, practicing extreme simplicity. He was fascinated. He returned to Greece—like Epicurus returning from his travels—but with a profoundly different conclusion than his older contemporary.
Pyrrho's key insight was this: for every argument, there is an equally strong counter-argument. This is called isostheneia—the equal strength of opposing arguments. Given this perfect balance, the wise response is epoché—suspension of judgment.
Notice what this means: you don't believe that skepticism is true. You don't affirm anything. You simply—in the face of equal arguments—refrain from judgment. And surprisingly, this refusal brings ataraxia—peace, tranquility. The same word Epicurus used! But achieved differently: not through pleasure, but through the cessation of the struggle to believe.
After Pyrrho, skepticism evolved through two main lineages:
Academic Skepticism (Arcesilaus and Carneades in Plato's Academy): These thinkers held that knowledge is impossible, but they still acted based on probability. They suspended judgment on theoretical matters while remaining practically engaged.
Pyrrhonian Skepticism (Sextus Empiricus, 2nd century AD): Sextus preserved and systematized Pyrrho's approach. He argued that skepticism is not a dogma but a way of life—a method for achieving peace through the abandonment of the search for truth.
Sextus provides a collection of "tropes" (modes, arguments) that show why we should suspend judgment:
The Trope of Contradiction: For every assertion, an equally strong counter-assertion can be made.
The Trope of Infinite Regress: To justify any belief, you need another belief to support it, which needs another, and so on forever.
The Trope of Relativity: All judgments are relative to the perceiver. What appears good to one appears bad to another.
The Trope of Hypothesis: Some claims rest on unproven assumptions.
These are powerful arguments. They anticipate modern philosophical problems—the regress problem in epistemology, relativism, the problem of the criterion. But they lead to a conclusion many find troubling: we cannot know anything with certainty, so we should stop trying.
For every claim, there is an equally strong counter-claim. Therefore, suspend judgment.
This is not mere agnosticism ("I don't know"). It is active suspension. You actively refrain from affirming anything. You don't say "I believe X might be true but I'm not sure." You say "I withhold judgment entirely." This is intellectually honest. It is also liberating—because it frees you from the exhausting demand to have opinions on everything.
Peace comes not from having answers but from stopping the search for them.
This parallels Epicureanism but inverts it. Epicurus said: simplify your desires, enjoy what you have, stop seeking more. The Skeptic says: stop seeking certainty, abandon the demand to know, and you will find peace. Both arrive at tranquility. The Epicurean through pleasure, the Skeptic through the cessation of intellectual struggle.
But here is a tension: Is the Skeptic really at peace? Or is the Skeptic simply more aware of the groundlessness of everything and has learned to live with that awareness? That might feel like peace, or it might feel like vertigo.
For any argument in favor of X, an equally strong argument against X can be constructed.
This is more radical than it sounds. It claims that no argument is definitively stronger than its opposite. Everything is perspectival. Everything is dependent on unproven assumptions. The Skeptic presents "tropes"—logical weapons—that neutralize any claim to certainty. In the perfect balance, judgment suspends.
Skepticism is intellectually honest. But here is what it cannot answer: How do you live without conviction?
You might suspend judgment on abstract metaphysical claims. But what about practical matters? If your house is on fire, do you suspend judgment about whether to leave? If someone needs help, do you suspend judgment about whether to help? The Skeptic's response is pragmatic: yes, act according to appearance and convention. Act as if things matter, even though you have suspended judgment about whether they truly matter.
But this feels like a dodge. Either things matter or they don't. Either your help can genuinely improve someone's condition or it cannot. The Skeptic seems to be sneaking back in conviction through the back door while claiming to have abandoned it through the front.
Also: What about love, justice, and meaning? These require conviction. They require you to judge that something is worth the risk. The Skeptic can achieve tranquility by suspending judgment on all these matters. But is that tranquility or anesthesia? Is it wisdom or just sophisticated escapism?
Three dates to lock into memory using your PAO system.
The founder of skepticism. Encode "03" and "65" from your PAO. Place your image at the moment of epoché—a philosopher about to judge, then stopping mid-judgment, suspending forever.
The journey that changed everything. Encode "03" and "20" from your PAO. Link to encounters with gymnosophists—naked philosophers sitting in perfect equanimity.
A life of epoché, ending in peace. Encode "02" and "75" from your PAO. Link to a quiet, unremarkable death—the ultimate indifference.
Cover the dates. Can you recall all three?
1. When was Pyrrho born?
2. When did Pyrrho travel to India?
3. When did Pyrrho die?
You have built 18 rooms. Now you arrive at a place of perfect balance, of arguments frozen in equipoise. Here lives Pyrrho and the Skeptics—philosophers who looked at the world and said: perhaps the bravest and most honest response is to withhold judgment. This is the room where certainty evaporates, but paradoxically, peace remains.
Where is Location 19? What place represents perfectly balanced judgment and the suspension of conviction?
Place these five vivid, paradoxical images in your Location 19:
1. A perfectly balanced scale, neither side ever falling—the scales of isostheneia, where every argument is met by an equally strong counter-argument.
2. A man walking calmly through a battlefield, unafraid, unaffected—Pyrrho's legendary indifference. Swords swing, but he does not judge danger to be bad, so fear does not disturb him.
3. Two philosophers shouting opposite conclusions, both equally convinced—the trope of contradiction made vivid. The Skeptic sees this and simply walks away, refusing to judge which is right.
4. A judge's gavel suspended in mid-air, never falling—epoché, the suspension of judgment frozen in eternal hesitation.
5. A blank page where an answer should be—"I do not know—and I am at peace with that." The greatest claim of Skepticism is not truth but tranquility through the abandonment of truth-seeking.
Describe exactly where you place each image.
Choose 2–3 of these questions to think through carefully.
The Skeptic suspends judgment on everything. But if you truly had no convictions, how would you choose between right and wrong? How would you love? How would you act?
Skepticism claims that for every argument there is an equally strong counter-argument. But isn't the claim that for every argument there is an equally strong counter-argument itself open to counter-argument?
The Skeptic achieves peace by giving up the search for truth. But is that peace or just numbness? Is it wisdom or sophisticated escapism?
The stories say Pyrrho walked in front of carts, climbed cliffs, ignored obstacles—indifferent to danger. Are these stories cautionary tales or celebrations of his philosophy?
The Skeptic suspends judgment on all matters. But some things demand judgment. If you see injustice, can you really withhold judgment and remain passive?
Modern science rests on conviction—that the universe follows laws, that reason can discover those laws. What would skepticism do to science?
We have just left the Stoics. They demanded self-mastery and virtue. Does the Skeptic's response to this—radical doubt and withdrawal—solve the problems Stoicism left unresolved?
Without looking back, write everything you remember about Pyrrho and Skepticism.
Retrieve without looking back.
c. 365 BC — Birth of Pyrrho of Elis (founder of Skepticism)
c. 320s BC — Pyrrho travels with Alexander to India (encounters gymnosophists)
c. 275 BC — Death of Pyrrho (lived and died in epoché)
Define these Skeptical concepts:
Epoché: Suspension of judgment; the active refusal to affirm or deny any claim
Ataraxia: Tranquility, peace—achieved through the cessation of the struggle to believe
Isostheneia: Equal strength of opposing arguments; the insight that for any claim, an equally strong counter-claim exists
Name and describe the three pillars of Skeptical thought:
1. Epoché: Suspend judgment on all matters. Do not affirm or deny anything.
2. Ataraxia Through Skepticism: Peace comes not from having answers but from abandoning the search for them.
3. Isostheneia: For every argument, an equally strong counter-argument exists. Therefore, judgment is suspended.
Walk through Location 19. List the 5 images:
Skepticism offers peace through the suspension of judgment. But what does it lose? What questions can Skepticism not answer?
We have climbed higher and higher. From the Milesians asking what things are made of, to Plato seeing eternal forms, to Aristotle reasoning about essences, to the Stoics mastering themselves, to the Skeptics withdrawing entirely. Now we turn to the last great pagan philosopher—one who did not withdraw but who looked at the whole universe and saw something transcendent: a single source of all reality, beyond being, beyond thought. We meet Plotinus and Neoplatonism.
