My answer is: No information can exist in a bare way. That is to say, any existence of information is premised on the existence of substrate, and the substrate can be hierarchical. In the same way, no information can be communicated or processed in a bare way if and only if it has been embedded in the substrate. In human information, substrate can be divided into sign, paper, etc., or other electronic devices. In genetic information, substrate can be divided into base, DNA or RNA, chromosome, cell, and organism. The study about the mode of existence of information is an important aspect of ontological research of information science.<o:p></o:p></span></p><p class=MsoNormal style='margin-top:4.65pt;text-indent:21.0pt'><span lang=EN-US style='font-family:"Times New Roman",serif'>In Terry’s statement: "Simply collapsing our concept (compression, collapse) of 'communication' to its physical substrate ……", or in Loet’s words: "One should not confuse communication with the substance of communication." Again, this is a hierarchy problem. Because no information can be communicated in a bare way, so the communication of information is premised on the communication of substrate, the same is true in the processing of information. Then, any communication of information is twofold: communication of information and communication of substrate. The study about the mode of communication and processing of information is the important aspect of dynamical research of information science.<o:p></o:p></span></p><p class=MsoNormal style='margin-top:4.65pt;text-indent:21.0pt'><span lang=EN-US style='font-family:"Times New Roman",serif'><o:p> </o:p></span></p><p class=MsoNormal style='margin-top:4.65pt'><span lang=EN-US style='font-family:"Times New Roman",serif'>Best wishes,<o:p></o:p></span></p><p class=MsoNormal style='margin-top:4.65pt'><span lang=EN-US style='font-family:"Times New Roman",serif'>Xueshan<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-family:等线;color:black'><o:p> </o:p></span></p><div><div style='border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0cm 0cm 0cm'><p class=MsoNormal><b><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri",sans-serif'>From:</span></b><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri",sans-serif'> fis-bounces@listas.unizar.es [mailto:fis-bounces@listas.unizar.es] <b>On Behalf Of </b>Loet Leydesdorff<br><b>Sent:</b> Saturday, November 18, 2017 4:19 PM<br><b>To:</b> Terrence W.

Shannon's (1948) definitions in "The Mathematical Theory of Communication". Information is communicated, but is yet meaning free. These notions of information and communication are counter-intuitive (Weaver, 1949). However, they provide us with means for the measurement, such as bits of information. The meaning of the communication is provided by the system of reference (Theil, 1972); in other words, by the specification of "what is comunicated?" For example, if money is communicated (redistributed), the system of reference is a transaction system. If molecules are communicated, life can be generated (Maturana).<o:p></o:p></span></p></div><div><p class=MsoNormal><span lang=EN-US style='font-size:10.0pt;font-family:"Tahoma",sans-serif'><o:p> </o:p></span></p></div><div><p class=MsoNormal><span lang=EN-US style='font-size:10.0pt;font-family:"Tahoma",sans-serif'>2. Information as "a difference which makes a difference" (Bateson, 1973; McKay, 1969). A difference can only make a difference for a receiving system that provides meaning to the system. In my opinion, one should in this case talk about "meaningful information" and "meaningful communication" as different from the Shannon-type information (based on probability distributions). In this case, we don't have a clear instrument for the measurement. For this reason, I have a preference for the definitions under 1.<o:p></o:p></span></p></div><div><p class=MsoNormal><span lang=EN-US style='font-size:10.0pt;font-family:"Tahoma",sans-serif'><o:p> </o:p></span></p></div><div><p class=MsoNormal><span lang=EN-US style='font-size:10.0pt;font-family:"Tahoma",sans-serif'>3. Interhuman communication is of a different order because it involves intentionality and language. The discourses under 1. and 2. are interhuman communication systems. (One has to distinguish levels and should not impose our intuitive notion of communication on the processes under study.) In my opinion, interhuman communication involves both communication of information and possibilities of sharing meaning.<o:p></o:p></span></p></div><div><p class=MsoNormal><span lang=EN-US style='font-size:10.0pt;font-family:"Tahoma",sans-serif'><o:p> </o:p></span></p></div><div><p class=MsoNormal><span lang=EN-US style='font-size:10.0pt;font-family:"Tahoma",sans-serif'>The Shannon-type information shares with physics the notion of entropy. However, physical entropy is dimensioned (Joule/Kelvin; S = k(B) H), whereas probabilistic entropy is dimensionless (H). Classical physics, for example, is based on the communication of momenta and energy because these two quantities have to be conserved. In the 17th century, it was common to use the word "communication" in this context (Leibniz).<o:p></o:p></span></p></div><div><p class=MsoNormal><span lang=EN-US style='font-size:10.0pt;font-family:"Tahoma",sans-serif'><o:p> </o:p></span></p></div><div><p class=MsoNormal><span lang=EN-US style='font-size:10.0pt;font-family:"Tahoma",sans-serif'>Best,<o:p></o:p></span></p></div><div><p class=MsoNormal><span lang=EN-US style='font-size:10.0pt;font-family:"Tahoma",sans-serif'>Loet<o:p></o:p></span></p></div><div><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Tahoma",sans-serif'><o:p> </o:p></span></p></div><div><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Tahoma",sans-serif'>------ Original Message ------<o:p></o:p></span></p></div><div><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Tahoma",sans-serif'>From: "Terrence W.
