Define any property of interest. Eg., O = "reacting with oxygen"
S is a simulation of O iff there is an inferential process, P, by which properties of O can be estimated from P(S) st. S does not implement O
Eg., "A video game is a simulation of a fire burning if, by playing that game, I can determine how long the fire will burn w/o there being any fire involved"
S is an emulation model of O iff ...as-above.. S implements O (eg., "burning down a dollhouse to model burning down a real house").
If P successfully produces the relevant behaviors of O (burning, light, etc), then P is an implementation of O. There's no separate "real O" floating out there that P fails to capture. In other words, when you are playing the game, there _is_ fire involved.
You define a 'real' implementation to exclude computational substrate, then use the very same definition to prove that computational substrate cannot implement 'real' implementations. It's circular!
