- Rick,
-
- I think the misunderstanding has been cleared up by your posting.

-
- Yes.
-
- >Why or why not?
-
- It seems a very plausible way that the linkages in the hierarchy can be
- connected with appropriate signs (and as I mentioned in a posting a few
- weeks ago, there seem to be 12 different ways that reorganization of this
- kind could be effected, so I'm not plumping for a mechanism).
-
- >Can you think of a behavioral test for such a model?
-
- Not offhand. And I think that a good part of this reorganising system
- is outside the individual, occurring on an evolutionary time-scale, so
- that aspect couldn't be demonstrated behaviourally.

-
- I admit the possibility, since we can never know when we are fooling ourselves.
- But see the postings to Tom and Bill yesterday. I hope that I will be able
- to satisfy you with what I plan to write in a more serious vein than
- impromptu net postings.
-
- Happy Xmas.
