Once you get into the theoreticals, its surprising how relevent quite
distant fields can become to each other. Any complex system - doesn't have
to be a conventional information processing system, could just be a big
hospital - has effects due to its complexity which tend to impress
themselves on those who have struggled to make them work.

So "There is no temporal paradox in bird origins"? I'm sorry but they're
wrong, period. I could spend my entire life arguing this one but they are
expert foresters in the Great Wood of Clad, obfuscating, diverting and
sapping one's energy. They would never admit defeat. Frankly, I would
rather spend my time reading Newton's works discussing the categories of
angels and the structure of heaven. Don't think lying with statistics is
beyond me, I've just got more worthwhile and much less boring things to do.

I do try to leave him out of all this as much as possible, referring to the
theory rather than to him. I'll continue to try but it's hard to avoid
mentioning him entirely.
But have you considered the possibility that he might appreciate someone
speaking up for his theory? Perhaps he has reasons of his own - I would in
his position - to go easy on it.

Look, this theory deserves to be mentioned EVERY TIME the alternatives are
covered, not "at the SVP" here and "some years ago" there. Even if *no-one*
supported it, the fact that the relationship between Ax and Vel could at
first glance quite easily be one way or the other surely requires in a
proper scientific appraisal the formal consideration of the possibility
suggested by the temporal occurence in the fossil record, before completely
submerging everybody in that vile Byzantine alchemy.

As you say, he can speak for himself. But he is a historical figure, and
besides, any honest person would agree that I am doing him more justice than
