What are ideas? One suggestion is that an idea is a possible
state of something physical, so whilst still only an idea it is something
possible but not actual or physical. I have an idea:it's time to go
and have a drink. As a physical system this change in my state
is a potential I have, unrealised and unactualised but real, a
real possibility. I can't go for this drink without being sustained
by legs, etc. And I may never get round to going for it.
Is going for a drink a product of my physical state? Well I may
allow thirst to persuade me to realise this idea/potential but what
about the idea of reading a particular book? Well I'm off for my
drink, but I'm pretty sure that physical is one kind of term, idea another,
and you can't replace one by the other.

There is quite a bit of research along these lines. Dan posted a link to an
article about this sort of thing recently.
