Learn Foundations with any AI

The modern trivium

Foundations is the operating system of this whole encyclopedia — the thinking skills that make every other subject learnable in the first place. Critical reasoning, clear communication, the scientific method, information literacy, and knowing how to learn: install these, and everything else goes faster.

It's also the most important node for using AI itself well. A sharp question and a sceptical eye are what turn a chatbot into a tutor. Set your level below, and treat this as the ground the rest is built on.

A map of the Foundations

The Enlightenment toolkit

The core thinking skills, each a small discipline in its own right.

Critical thinking & logic — valid argument, informal fallacies, and probability and Bayesian reasoning.
Rhetoric & communication — writing clearly, speaking well, and structuring a persuasive case.
The scientific method & epistemology — evidence, experiment, and "how we know what we know."
Research & information literacy — evaluating sources and spotting misinformation.
Numeracy & data literacy — reading statistics and charts, and grasping risk and scale.
AI literacy & prompt craft — how these models work, and how to verify what they tell you.
Learning how to learn — memory, spaced repetition, retrieval practice and metacognition.

§03

The canon

The sources of clear thinking

These skills have a real intellectual history.

Aristotle — founded both formal logic and the systematic study of rhetoric.
Francis Bacon — the early champion of evidence and experiment over received authority.
The Enlightenment — the age that made reason and public argument the test of claims.
Thomas Bayes — the mathematics of updating your beliefs when new evidence arrives.
Hermann Ebbinghaus — measured memory and forgetting, giving us spaced repetition.
Daniel Kahneman — mapped the systematic biases that clear thinking has to work against.

§04

The live debates

Debates about thinking itself

Even the basics are genuinely contested.

Can critical thinking be taught in general? Or only within a subject you actually know?
Is there a single "scientific method"? Popper, Kuhn and others disagree about how science really works.
Experts vs thinking for yourself. When to defer, and when deference becomes a cop-out.
Does AI erode thinking? Whether leaning on a tutor that gives answers builds or weakens the mind — the question this whole site has to answer.

§05

Where to start

A route in

A route in — and it makes everything else on the site work better.

Run Orientation on critical thinking, or on "learning how to learn."
Use the Socratic tutor to practise argument-mapping on a claim you actually care about.
Read the Method page — it's this toolkit applied to the site itself.
Then carry these habits into every other node.

The whole encyclopedia rests on one skill: asking a good question and checking the answer. Start here.
