Lectures
The twelve lectures, who gives them, and the evidence each one puts on the table.
Mondays, one hour, twelve of them. Every lecture has slides and they are linked from its page, before the lecture rather than after it — there is nothing in them worth withholding, and reading ahead makes the Thursday seminar better.
A lecture here is not a summary of the week. It is the place where the evidence gets put in front of you properly: the actual experiment, the actual numbers, and the actual disagreement where there is one. That is why several of these pages name a single paper and spend most of their length on it.
Three of us teach. Halvard takes weeks 1, 11 and 12: the week that sets the evidence standard, and the two that apply it to the course’s own sources and then to the people in the room. Rosalind takes the comparative weeks — 2, 3, 4, and then 8 through 10. Tuyet takes 5, 6 and 7, the three weeks where the machinery gets internal enough to model itself.
Two lectures argue against their own content in the last twenty minutes, and they are marked as such on the page. That is not a rhetorical device. Week 6 presents predictive processing and then gives you the dark room problem; week 9 presents Nagel and then gives you Akins. If a framework cannot survive the hour it was introduced in, you should find that out in the room.
Too large to represent
The lecture sets the constraint and nothing else. A finite system inside a larger world cannot hold that world, so it holds a compression, and compressions lose things.
Week 1 · 22 February 2027
What a sense organ is for
Sensing is not reception. It is a commitment about which distinctions are worth paying for, and the mantis shrimp is the case that makes this undeniable.
Week 2 · 1 March 2027
Memory outside the head
How the past constrains the present with no neurons involved, and the ninety-year mistake that arrived with it.
Week 3 · 8 March 2027
Correlation, standing in for cause
The first mechanism that can be systematically misled, and the fact that nothing inside it can detect the difference.
Week 4 · 15 March 2027
The map, and what it was really for
Representing structure you are not currently sensing — and the 2016 result suggesting the machinery was never specifically spatial.
Week 5 · 22 March 2027
Perception as construction
The lecture where the direction of flow reverses, and most of what you take to be sensing turns out to be generation checked against input.
Week 6 · 29 March 2027
Modelling the modeller
Why a self-model must be a summary, and what that predicts about introspective reports.
Week 7 · 5 April 2027
A million neurons is plenty
The brain-size puzzle, and why counting the right thing makes most of it disappear.
Week 8 · 12 April 2027
Another architecture entirely
An animal whose nervous system is mostly not in its brain, and a famous question that may be the wrong shape.
Week 9 · 19 April 2027
Cognition outside the individual
Swarms, notebooks and committees — and the finding that a group's failures are not its members' failures added up.
Week 10 · 26 April 2027
The catalogue, graded by its own scheme
Three separate research programmes that got merged into one slogan, and how much of the famous version did not replicate.
Week 11 · 3 May 2027
The blind spot
Nothing new. The account from eleven weeks, aimed at the person holding it, and the week 1 question in a form no card will find.
Week 12 · 10 May 2027
