      Hi Bill - for me the problem is more immediate. I'm left worrying why I
      think I'm mentioning self-evident considerations, yet people I am
      satisfied have more intelligent/highly-developed positions on such
      matters see me misconceived.

      I'm thinking I'm just out of context on something.....haven't adequately
      distinguished the issues being discussed...you agree with what I'm
      saying but what I'm saying is irrelevant in the context.

      I find that explanation more comforting than the alternatives of either
      I am truly plotless, or this is one of the instances that history is
      littered with, where the gifted and talented manage to pickle an avenue
      of thought by ignoring some glaringly self evident truths..... on
      grounds of the truth is not always self evident.

      How about the OO distinction between a class and an instantiation of a

      You're an instance of your exact biological arrangement. An identical
      you is another instance.

      It's really not that much more sensible to say a copy of you being
      created somewhere else is a good reason for you to be destroyed in the
      transporter, than it is to say that because I exist you can safely die
      in the transporter. I'm not far off identical to you Bill. A few
      differences here and there but we're probably talking 99.x% identical.
      What if the transporter creates your copy with just a moleculres in the
      wrong order...will it still be you? How much is not enough.

      Rgds, al

        Let us be clear. I agree, I was saying this for those who introduce
        non Turing emulable telepathic connection, ad absurdum.

        Or like when the two brains are identical until they interact with
        very different environment, like in the duplication thought experiment.

        Sometimes it makes sense, especially when going back in a discussion
        after some interruption, and when some points refer to old agreements.
        But I agree, let us not exaggerate. Sorry.
