I agree mostly, but I would point out that although we can determine when a message is passed, we can't be sure that a message is not being passed. We infer messages from observing behaviors which are familiar to us, but there be much more going on than we would know to imagine. How much could an alien with a telescope learn by looking at your behavior - or maybe he is only looking at your car and assumes that you are some kind of symbotic assistant?

Right. Stanislaw Lem has written stories on the theme of the near impossibility of understanding aliens.

All of that in the quote is Hofstader's writing, btw. Only the comment at the 
end is mine.

Yes, I understood that.
