Neurophilosophy sets off a great debate in Blog comments

Mo Costandi (Neurophilosophy) over at "The Guardian" describes an experiment that demonstrates (perhaps) that "Leaning to the left makes the Eiffel Tower seem smaller."

The really fascinating part, however, is the exchange in the comments section that takes place between Andrew D. Wilson and Rolf Zwaan. I also liked neuroskeptic's comment:

A philosophical question for anti-representationalists: Do you think any entity could have representations? Could we build a robot with representations? Or could we discover aliens with representations? If not, it seems that you are saying that representations are just impossible a priori. Which is fine, but then it's not an empirical question, it's a philosophical one. On the other hand, if you think that having representations is possible, but it's just that humans don't as a matter of fact have them - how would we tell the difference between ourselves, and an alien or robot who did have representations? What would they be able to do that we couldn't?

That's quite smart, isn't it?
