It is assumed that the reader has some basic familiarity with settheory and logic. Although logic has been adopted as a language for formalisation in most formal theories of diagnosis, settheory oers a powerful alternative. It is interesting to interpret this result in settheory. This leads to the 'comprehension axiom', the second axiom of settheory. We consider the positive settheory with equality described these and propose a candidate model. The constructive nature of the logic is more limited than approaches based on settheory or higher-order logic, but leads to two important advantages. An informal justification for this axiom can be drawn from settheory where a function is defined as the set of all argument-result-pairs. All the rest - settheory, analysis and the like - he called the "ideal" part of mathematics. Chapter 1 gives a background on elementary settheory (set-operations, functions and relations) and partially ordered sets (with emphasis on lattice structures). Many other theorems in extremal settheory provide such elegant characterizations of the largest possible family of sets given certain information on their intersections. The standard operators relate the new concepts to standard settheory, and remain useful for defining well-founded constructions. The basic notions of rough settheory are for twin-concept classification and discrete attribute values. So one cannot be sure that the other basic ideas of settheory are not also flawed. This was already felt as a problem in the early developments of settheory. These examples are from corpora and from sources on the web.
