Lets suppose that in the year 2115 neurologists tell us that theyve figured out how the brain actually understands things. What would that mean? Precisely that they can explain it in terms of components that do not themselves understand.
Perhaps they tell us:Heres how the mind understands. The mind is composed of three components, the blistis, the morosum, and the hyborebus. The blistis and the morosum have nothing to do with understanding; the part that understands is the hyborebus.We dont have to know what these things are to know that theyve failed. This cannot be an explanation of understanding, because it simply transfers the problem from the mind to the hyborebus. Its like explaining vision by saying that the optic nerve brings the image from the eye to the brain, where its projected on a screen thats watched by a homunculus. How does the homunculuss vision work?

This will be the first of a series of six or seven articles, aimed at explaining things that are fundamental to human experience (or so we think) and which boggle the mind when we try to analyse them: meaning, consciousness, knowledge, the self, free will, morality. The trouble, I believe, is not that these things have no explanation, nor even that we cant comprehend the explanation. The trouble is drawn out by the quote above. We dont have a problem applying it to most things: we can all accept that a car doesnt have a smaller car under its bonnet driving on a little treadmill to make the big car go, and that if it did it wouldnt explain anything because youd still have to ask what makes the little car go.But with the Imponderables, as I shall call them, our intuitions run the wrong way.
