@coberst phil,
The 'mind as computer' idea is intrinsically flawed and this can be easily demonstrated by the manner in which they 'remember' facts.
A computer remembers smaller bits of informantion more easily than larger ones.
A human mind, however remembers larger pieces of information more easily.
When you ask a child to remember the alphabet for the first time, they find it nearly impossible to remember 26 pieces of data. But when you add a tune to the data, it is remembered more easily.
Similarly when swatting for an exam, if you need to remember a list of items, its much much easier if you make up a story around that list. The more assosiations you make with that list the easier it is to remember - paradoxically.
In the same manner, even remembering a 5-digit pin code becomes much easier if you remember the numbers in groups with meanings. eg : 12536 is easier to remember if you note that the number is also 5x5x5 ... 6x6
But having said that, I agree with the notion that philosophy needs to be grounded on a physical level. Especially when we are dealing with the humanities. Ethics for example that tries to contrive characters in examples often makes assumptions that do not gel with psychology. It would be better to base such ideas on real people.
