Dear Xueshan - re Nalewajski's conjecture that molecular systems have 
information I am skeptical. The word information originated with the idea of 
forming the mind according to the OED. Information as far as I am concerned 
requires a sentient being to receive and understand it. Molecules and atoms 
react to forces not information. They have no idea of the forces acting on 
them. They are not informed as they have no sentience that can be informed. 
Information requires an interpretant for which the signal has meaning. 
Shannon's  information theory is merely signal theory as all he is concerned 
with is how well a set of symbols or a signal are transmitted from the sender 
to the receiver. The ability of the receiver to decipher the signal or 
interpret the signal  has no bearing on the reception of Shannon information. 
Shannon information has nothing to do with meaning. A set of random numbers has 
the maximum amount of Shannon information and yet has no meaning. If my set of 
symbols have meaning for you, whether or not you agree with the premise they 
represent, then they are information. As for a molecule or even a flower or a 
penguin they are not information. In other words information has to inform as a 
grammatical analysis of the word information implies. A representation 
represents, a contradiction contradicts, a saturation saturates and in general 
an "X"tion "X"es and therefore information informs or at least has the 
capability of informing. So while a text in the Basque or Albanian languages 
might not inform me because of my inability with these languages they are 
capable of informing those familiar with the Basque and Albanian languages 
respectively and are therefore informaton. A random set of letters cannot 
inform anyone yet they have maximum Shannon information. Information is a 
tricky thing. 

This line of thought raises the question of whether or not DNA is information. 
DNA does not inform a sentient being yet it does catalyze and hence instructs 
how RNA is produced which in turn catalyzes and instructs how proteins are 
created which in turn gives rise to bodily functions. Therefore we suggested 
that DNA represents a different form of information from Shannon information 
which we called biotic or instructional information. The argument can be found 
in the paper  Propagating of Organization: An Inquiry by Stuart Kauffman, 
Robert K. Logan, Robert Este, Randy Goebel, David Hobill and Ilya Smulevich. 
published in 2007 in Biology and Philosophy 23: 27-45. I am happy to share this 
paper with anyone requesting it.
