Hello Loet, Bob U, Alex et alia - I agree with Bob U when he wrote "The problem
is that information is not an absolute.” As I have stated before on this list
information is relative and depends on the context.
And I agree with Loet when he wrote, "Different systems of reference, of

Dear FISers - I enjoyed Jose’s distinction of meaning and sense making.
Employing McLuhan’s notion of figure and ground in which one can only
understand a figure in terms of the ground in which it operates, I would
therefore say that meaning is figure and sense-making is the ground in which

Hi Moises and FIS colleagues. The gravity wave that was detected last Sept
informed us of the event of two black holes colliding 1.3 billion years ago -
we learned how much energy was released which was approximately the 3 times the
mass of the sum times c squared. We also learned that the

Dear Loet - I agree with your remarks: "Bob and his colleagues define
information (2008; p. 28) as “natural selection assembling the very constraints
on the release of energy that then constitutes work and the propagation of
organization.” This may have meaning in a biological framework, in

Dear Colleagues - I have been reading the posts in this thread and enjoying the
conversation. I started playing with the notion of discipline and came up with
these undisciplined playful thoughts which I believe provide an interesting or
at least an alternative perspective on the notion of a

silent in these final days. It was nice counting with Terry chairmanship, he
has had a very hard work with all those responses--thanks a lot to him.

Dear all - my take on this post is that the question of whether physical
processes are information is like the question: Is there a sound if a tree
falls in the forest and no one is there to listen? This is like the Zen koan:
what is the sound of one hand clapping If no one is in the forest are
the other questions in the fullness of time but now I must
return to my duties. Thanks to John and Pedro for raising such an interesting
topic.
I look forward to our discussion and any comments on my remarks.

Hey Stan - I agree with the way you characterize the role of logic as a
linguistic mechanism. Logic connects one set of statements, the premises, with
another set of statements, the conclusion. Without challenging your remarks I
would suggest that like the case with the poets it is sometimes
with multiple ways of describing it
each of which employs a particular metaphor. The computational universe is just
one example in a long line of cosmic metaphors and as our science and
technology evolves so will the metaphors to describe this cosmos of ours.

Dear Joseph - once again your post was most stimulating, provocative
