A conjurer at a table performs the cups and balls to a rapt crowd, while a man behind the gaping spectator lifts his purse

Is consciousness a magic trick?

You seem to have an inner world: a private show of colours, sounds and feelings that no brain scan could ever capture. Daniel Dennett argued that this is how the brain's work seems from the inside, not how it is. The task is to explain the trick, not to be dazzled by it.

This site starts from Dennett, and from one short essay in particular, "Illusionism as the Obvious Default Theory of Consciousness" (2016). In it he compares the philosophy of mind with stage magic. We know a conjurer has not really sawn a woman in half, even when we cannot see how it was done. Dennett says we should treat the apparent magic of experience the same way.

From there, each major view of the mind gets its own page: what it claims, what drives it, and where it parts company with Dennett. His closest allies come first, then a long history running from Aristotle's soul to Ned Block's nation of China, and finally the thinkers who reject his picture outright. Each page has an interactive figure of its own, from Leibniz's mill to Mary's black-and-white room.

Dennett's view Stage magic, the Cartesian Theatre, multiple drafts and the red stripe that isn't anywhere, in six interactive figures.
