Stoicism

300 BC

Stoicism isn’t about emotional control—it’s about binding ethics to cosmic reason, and it fails when that cosmos vanishes.

Stoicism is a philosophical movement and practical guide to living, emphasising daily self-discipline and moral improvement, which originated in the Hellenistic period of ancient Greece and continued well into the Roman Imperial period.

    The Painted Porch

    Stoicism began as public philosophy in Athens’ Agora—not in libraries or courts, but in the open colonnade of the Stoa Poikile.

  2. 2:12
    Logic Before Language

    Chrysippus built a logic of propositions, not terms—making Stoic reasoning structural, not categorical.

  3. 3:56
    Nature Is Reason

    Living in accordance with nature meant obeying reason—not instinct, not gods, not custom—but the rational order of the universe.

  4. 5:34
    One of Two Logics

    Stoic logic stood equal to Aristotle’s: one of only two great classical systems—and the only one built on propositions.

What the thing is

Stoicism is a philosophical movement and practical guide to living. It is systematically structured around logic, physics, and ethics.

Where it came from

It was founded in the ancient Agora of Athens by Zeno of Citium around 300 BCE. It emerged from the Cynic tradition and was taught publicly at the Stoa Poikile.

What it gets right

It treats ethics as inseparable from logic and physics. It insists that virtue is the sole good. It grounds moral action in rational alignment with universal order.

What it gets wrong

It collapses human emotion into error. It treats external goods—health, safety, relationships—as ‘indifferents’, denying their material weight in lived experience.

Why it matters now

Its propositional logic remains one of the two great classical logic systems. Its insistence on reason over reaction resurfaces in cognitive-behavioural therapy and modern resilience discourse—but stripped of its physics and logic, it becomes self-help, not philosophy.

Is it worth your time

Yes—if you want a rigorous, logic-based framework for ethical reasoning rooted in nature and reason, not faith or feeling.

Crypto-anarchyCrypto-anarchy is a movement, not a prophecy. It uses cryptography to enable anonymity, free speech and trade. It emerged from Timothy C. May’s 1988 manifesto and the 1992 cypherpunk founding. It gets right that code can constrain power—but wrong that it will collapse the state. A 2022 study confirms its political irrelevance—yet its architecture remains vital for Internet-native dissent.
8:55
Free software movementThe free software movement is a precise, principled refusal of proprietary control over software. It began in 1983 with GNU and institutionalised in 1985 with the FSF. It gets right that software freedom must be guaranteed—not merely permitted. It gets wrong that licence compliance alone secures user agency. Its relevance has grown as software becomes infrastructural—but its methods remain rooted in individual refusal and collective development.
8:42
AbsurdismAbsurdism names the friction between human meaning-making and cosmic silence. It does not resolve it. It insists on the tension. It is precise, unsparing, and useless as advice.
9:02
AccelerationismAccelerationism is a theory that uses capitalism’s own mechanisms to dismantle it. It emerged from Deleuze and Guattari’s 1970s work, was amplified by Nick Land’s CCRU in the 1990s, and named by Benjamin Noys in 2010. It correctly identifies internal contradictions in capitalism—but wrongly assumes those forces can be steered without reproducing domination. Its influence lives less in movements than in how technocrats, AI ethicists and climate strategists talk about scale and speed. It is worth your time only if you want to dissect that assumption—and see where it breaks.

Straight edge wasn’t about purity—it was about drawing a line in the mosh pit and daring the scene to cross it.
