Let me briefly catch up with these dense exchanges about
representation, simulation and emulation, by reacting to what you
wrote at the end of your last post : the brain would offer an example
of emulation in the way it creates a model of the world from sensory
inputs from outside and inside the body.
As far as I know, this is the proccess that Varella and his collegues
analyzed and named "enaction". They were very suspicious about the
term "representation" as beeing based on the conception of reality as
existing a priori, and of counscioussness as a process of mirroring
this a priori reality. They developed their concept of enaction as
refering to a coupling of the "brain" with the "reality" through
sensory inputs, stressing the importance of awareness, not as a
mirroring process, but as the creation of a "world" which is neither
totally in the brain itself nor in an a priori reality, but which
belongs to both.
Of course, their researches would have to be analysed more in depth
than what I just sketched, as well as the direct and undirect
influences they had on recent conceptions of counscioussness, as, for
instance, neuroconstructivism (see, among many other things, V.
Ramachandran's research about the fantom limb syndrom). In my
opinion, their concept of enaction strongly questions the concept of
representation and its sub categories of simulation and emulation.
