It would seem that what Bateson is saying is that "mind" is a process which EMERGES from interactions "beyond the skin." Thus, it goes one step beyond the "systems argument" which Searle attempts to object to. Searle wants to argue about whether or not a collection of simple agents (call them neurons or symbol processors or whatever) can have properties AS A COLLECTION which none of the components have as individual members of the collection. Anyone who has worked with systems know that such properties do indeed exist; but both Searle and Harnad would have us believe that "understanding" is too sacrosanct to be such a property. Bateson takes another approach which seems a little less awestruck with the need to distinguish man from machine. He is saying, as I understand it, that "mind" cannot emerge merely from the interactions of components within an individuals body but, rather, from the interactions of that body and its components with other exterior entities. In other words, Bateson seems to be buying into the "systems argument;" but he wants to extend the boundaries of the system beyond those considered by Searle . . . outside the man in the room, outside the room itself, to include the room and anything (human or otherwise) which might interact with it. I, for one, happen to like this new spin on things. I regard it as further evidence of how careful we have to be when we approach a word like "understand." It seems as if Bateson is saying that asking whether or not the man in the room understands Chinese is a silly question, and asking whether or not the "system" of the room and all its interacting contents understands Chinese is no better. My reading of Bateson is that he feels the only appropriate question to ask is whether or not there is a manifestation of understanding in the interactions that a Chinese person has with the room. Since Searle seems to have deliberately set up his GEDANKEN experiment to assure such a manifestation, there does not seem to be much room (pun intended?) for argument.
