I disagree that it’s our best model; I find it too misleading.
Got a better one?
Also, the evidence that the brain engages in symbol processing is very weak...
Presumably your brain is processing symbols right now, as your read this.
You probably are questioning if there is symbol processing going on underneath the obvious top level—somewhere between quantum physics and the chemistry of neurons, and thinking. The answer appears to be that the brain uses a whole variety of representations, which vary in how much they look like symbols or like other things, such as image maps.
