> the network structure contains information (in the Shannon sense) about the environment ... the way a map represents a territory instead of how a guide book does ;) Or the way a 3D structure made out of the same 20 joined amino-acids could represent either an enzyme (the code) or a protein (the data) and that there is no distinction between code and data (which is the great insight realized in the original Lisp. It is not a coincidence that Lisp was the language or the classic AI. Sorry for the reminiscence - just love this part).
