 Normality in Spohn’s theory is explicated in terms of background conditions, not in terms of probabilistic relations between the antecedent predicate and the consequent predicate. If someone believes that the law \(f(X)=Y\) holds, then she believes that this functional relation holds under normal conditions \(N\), which means in terms of Spohn’s ranking functions that the law \(f(X)=Y\) is believed with rank zero, i.e., it is true in all normal worlds of a ranked world model. Such a ranked world model consists of a set of possible worlds together with a ranking function which attaches to each world a natural number \(0, 1, \ldots ,n\) specifying its rank. Worlds with rank 0 are the most normal worlds, worlds with rank 1 contain exceptions from normal conditions (1st degree exceptions), worlds with rank 2 exceptions from those exceptions (2nd degree exceptions), etc.
