Remains the need to specify: 1. The first difference [cf. Shannon's information bits]; 2. The second difference [cf. Brillouin's negentropy]; [KM] Loet, if you stick to first-order logic, there would be no need for recruiting an observer for the decidable theoretical edifice. Both Shannon's information and Brillouin's information-cum-thermodynamics belong to first-order logic as implying that the distinction between the existential quantifier and the universal one applies only to the subject. The role of measurement in first-order logic is at most secondary and no more than confirming the theoretical predictions. However, if you consider the difference making a difference making a further difference ad infinitum, the resulting proposition would be of the type following at the least second-order logic in the sense that quantification would also apply to the predicate. If one further wants to see a proposition of second-order logic decidable, some qualifier would have to be implemented of course naturally. That natural aspect would make biology quite unique in the material world. This has been my second for this week. Koichiro
