While quantum coherence is about the superposition of the states in a given single system on a definite Hilbert space, quantum correlation is about the correlation between different systems. Measurement is exclusively for the correlation between the two different systems, in which one is called a system to be measured and another one is called a measurement apparatus. The deed of measurement is practiced by the apparatus absorbing the quantum particles such as photons, electrons, atoms and molecules emitted from the system in focus. <o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:10.0pt;font-family:"Arial",sans-serif;color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:10.0pt;font-family:"Arial",sans-serif;color:#1F497D'> On the other hand, any theoretical enterprise may be inclined to take the stance making whatever closed system contrast with a theoretician external to the system. One exaggerated example is the dichotomy of TOE (theory of everything) and a committed theoretician sitting outside of the universe (then, where?). The externalist stance is the rule of conduct adopted for setting only one system, no matter how big or small it may be, against the concerned theoretician. No measurement is in need there.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:10.0pt;font-family:"Arial",sans-serif;color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal style='text-indent:15.0pt'><span lang=EN-US style='font-size:10.0pt;font-family:"Arial",sans-serif;color:#1F497D'>There is no difference between quantum correlation and coherence to the strict externalist because only one system is allowed there. In contrast, the difference between the two would become a serious matter to the practicing physicists paying due attention to the act of measurement. Which stance to take out of the two of the externalist’s and the internalist’s would be our choice. Information may also follow suit.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:10.0pt;font-family:"Arial",sans-serif;color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:10.0pt;font-family:"Arial",sans-serif;color:#1F497D'> Koichiro Matsuno<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:10.0pt;font-family:"Arial",sans-serif;color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:10.0pt;font-family:"Arial",sans-serif;color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:10.0pt;font-family:"Arial",sans-serif;color:#1F497D'><o:p> </o:p></span></p><div><div style='border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0mm 0mm 0mm'><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 [mailto:fis-bounces@listas.unizar.es] <b>On Behalf Of </b>tozziarturo@libero.it<br><b>Sent:</b> Wednesday, October 4, 2017 6:01 AM<br><b>To:</b> fis <fis@listas.unizar.es><br><b>Subject:</b> [Fis] Heretic<o:p></o:p></span></p></div></div><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p style='margin-top:0mm'><span lang=EN-US>Dear FISers,<br>After the provided long list of completely different definitions of the term "information", one conclusion is clear: there is not a scientific, unique definition of information.<o:p></o:p></span></p><p><span lang=EN-US>Nobody of us is able to provide an operative framework and a single (just one!) empirical testable prevision able to assess "information". <br>For example, what does "semantics" and "meaning" mean, in empirical terms?<br>Therefore, to talk about information is meaningless, in the carnapian sense. <o:p></o:p></span></p><p><span lang=EN-US>Judging from your answers, the most of you are foremost scientists.
