> What is the problem? Don’t we have a ‘representation’ of the dollar bill ‘stored’ in a ‘memory register’ in our brains? Can’t we just ‘retrieve’ it and use it to make our drawing? We can have a representation of a dollar bill, and you can see that the student retrieved that representation: he drew a picture. Sure, the representation is not exact, and some details have been omitted, but this is true of all representations, even computerized ones. Uber does not store an exact representation of every car; they cannot tell me that there is a dent on the back side of the car picking me up. Yet, my phone relays that a "silver Honda with plates XXXX" is picking me up — a representation of the car, and one good enough to get the job done. > no image of the dollar bill has in any sense been ‘stored’ in Jinny’s brain. And how not? The student was, again, able to draw a dollar bill. It wasn't perfect, but neither is a JPEG photo. > McBeath and his colleagues gave a simpler account: to catch the ball, the player simply needs to keep moving in a way that keeps the ball in a constant visual relationship with respect to home plate and the surrounding scenery (technically, in a ‘linear optical trajectory’). Perhaps this is how stuff functions, approximately, but it doesn't mean that it is the only means by which the brain could accomplish the task. I can throw and catch objects without looking at them — without a "constant visual relationship with respect to […] the surrounding scenery" — so, how can I do this?
