So we should understand that you would criticize any notion, sometimes
brought by physicists, of "block-universe". Time would be a primitive?
What about relativist notion of space-time?

BTW I agree with most of your post (of 09/08/2006) to David. At the
same time I'm astonished that you seem attracted by the idea of making
time a primitive one. I know that some respectable physicists do that
(Prigogine, Bohm in some sense), but many physicist does not (Einstein,
Of course it is more easy to explain that consciousness supervene on
number relations to someone who already accept consciousness could
supervene to a block-universe than to someone who want time (or
consciousness, or first person notion) to be primitive.

Of course I believe that once we assume the comp hyp. there is no more
choice in the matter.

Let me comment your other post in the same reply (to avoid mail box

Nice. It means you get the seven steps of the 8-steps version of the
UDA. (Universal Dovetailer Argument).
Thanks for resending the 15-steps version of it, it can help. Now I
think that my SANE paper, which contains the 8 steps version of the
UDA, is, despite minor errors, the closest english version of my Lille
thesis, and even better with respect to readability. (Except that it
lacks, like the 15 steps version) the movie-graph argument). Available
