Dear James, thank you for the widening of this discussion.
Order and Information Let us not close this session on the historical perspective of the modern concept of Science yet. Loet’s thoughtful remarks about the relation between information and order bring us back to some deep problems they were addressing in the Middle Ages. The discussion about the relative importance of the universalia vs. the re (also known as Occam’s) can be restated in today’s terms as follows: is the idea behind the thing more useful as a description of the world as the descriptions of the things themselves? In Loet’s view, there exists a framework within which we can observe how the actual states of the things are. Therefore, in this approach there is no need for a separate concept of order; as each possible alternative is a priori known, it is the information content that gives a description of the world. By information, this approach means the deviation of the actual cases from the ideal-typical case, in which an order exists. (universalia sunt ante rem) The opposing view explains information by means of the axiomatic idea of order. The system is in the same fashion closed, and every possible alternative is equally known a priori. The difference in viewpoints lies in the focusing on the properties of the ideal-typical case vs. the actual types of cases. (universalia sunt post rebus). The numbers offer a nice satisfying explanation. As we order the things, we encounter ties. (A sort on 136 additions will bring forth cases which are indistinguishable with respect to one aspect.) The members of a tie can represent the universalia. (“All additions where a+b=12” is e.g. a universalium) The actual cases will – almost – each deviate from the ideal-typical case. The information content is then the deviation of the actual cases from the ideal-typical state, as Loet defines, and concurrently an implication of which order prevails, as the opposing view suggests. So it is the same extent and collection which both see, but the names are different as is different the approach of calculating it. A reorder creates different ties, therefore a different information content. The difference between the Middle Ages and today is, in my view, that they had no possibility to face the idea that there is no ultimate ordering principle behind the many obviously existing ordering principles. Our generation has credible news about societies which are ordered in a completely different fashion and yet are not struck down. We have experienced too many ideal orders to believe that any such exists. Karl 2011/3/24, Pedro C.
