Dear John and Stan,
Your both hierarchies are good only if you believe in God.
But this is believe, not science.
Sorry, nothing personal!
Friendly regards

Not quite the same hierarchy, but similar:



It from bit is just information, which is fundamental, on Seth Lloyd’s 
computational view of nature. Paul Davies and some other physicists agree with 

Chemical information is negentropic, and hierarchical in most physiological

Pedro -- Your list:


physical, biological, social, and Informational


is implicitly a hierarchy -- in fact, a subsumptive hierarchy, with the 
physical subsuming the biological and the biological subsuming the social.  But 
where should information appear?  Following Wheeler, we should have:


{informational {physicochemical {biological {social}}}}

Thanks, Ken. I think your previous message and this one are drawing sort of the 
border-lines of the discussion. Achieving a comprehensive view on the 
interrelationship between computation and information is an essential matter. 
In my opinion, and following the Vienna discussions, whenever life cycles are 
involved and meaningfully "touched", there is info; while the mere info 
circulation according to fixed rules and not impinging on any life-cycle 
relevant aspect, may be taken as computation. The distinction between both may 
help to consider more clearly the relationship between the four great domains 
of sceince: physical, biological, social, and Informational. If we adopt a 
pan-computationalist stance, the information turn of societies, of 
bioinformation, neuroinformation, etc. merely reduces to applying computer 
technologies. I think this would be a painful error, repeating the big mistake 
of 60s-70s, when people band-wagon to developed the sciences of the artificial 
and reduced the nascent info science to library science. People like Alex 
Pentland (his "social physics" 2014) are again taking the wrong way... Anyhow, 
it was nicer talking face to face as we did in the past conference!

best ---Pedro

Sorry to have been too disruptive in my restarting discussion post--I did not 
intend to substitute for the Information Science thread an alternative way of 
philosophy or computing.  The references I listed are indicative of some bad 
thinking as well as good ideas to reflect upon.  Our focus is information and I 
would like to hear how you might believe the formal relational scheme of 
Rosenbloom could be helpful?
