What does it mean
to know something?

Seven interactive thought experiments drawn from the Stanford Encyclopedia of Philosophy — tacit knowledge, the knowing body, situated epistemology, and the AI consciousness boundary.

Beyond Propositions

Ryle's regress shows that skills can't be fully reduced to rules — applying any rule requires knowing how to apply it, all the way down.

The Knowing Body

Cognition isn't housed in the brain and borrowed by the body — it's constituted by the body's engagement with the world.

Who Knows What

The knower's position isn't bias to subtract — it's epistemically constitutive. Objectivity requires locating yourself, not erasing yourself.

How it works

Each app is a thought experiment, not a lecture.

  1. 1
    Pick a topic — choose one of the seven philosophical threads below.
  2. 2
    Engage the argument — the app walks you through the key positions and challenges your assumptions.
  3. 3
    Work through it — write, respond, try to defeat the argument. Your reasoning is saved so you can return to it.
  4. 4
    Build your own view — every app ends with the AI implication: how does this bear on what AI can and can't know?

Seven apps. Seven arguments.

Each draws directly from a Stanford Encyclopedia of Philosophy entry.

Knowing How vs. Knowing That
Knowing How vs. Knowing That

Try to reduce a skill to a list of propositions — Ryle's regress argument shows why it always fails.

Embodied Cognition Explorer
Embodied Cognition Explorer

Four thought experiments where you can't separate cognition from the body — the cane, the dancer, the native speaker, the phantom limb.

Phenomenology: First-Person
Phenomenology: First-Person

A guided phenomenological exercise — Husserl's intentionality, Heidegger's tool-being, Merleau-Ponty's body schema.

Situated Knowledges
Situated Knowledges

Haraway's view from nowhere, Harding's standpoint epistemology, Fricker's epistemic injustice — the knower's position as epistemically constitutive.

Virtue Epistemology
Virtue Epistemology

Four vignettes — evaluate the reasoner's intellectual character, not just their conclusion. Sosa's reliabilism vs. Zagzebski's responsibilism.

The AI Consciousness Boundary
The AI Consciousness Boundary

Chalmers' hard problem, Nagel's bat, Searle's Chinese Room, philosophical zombies — why language production isn't proof of interiority.

The Extended Mind
The Extended Mind

Clark & Chalmers: Otto's notebook is part of his memory. Four escalating cases — does AI extend your mind or shrink it?
