CONTEXT

This text is part of the subject COMMON SCIENCE as Sustainable Applied Empirical Theory, besides ENGINEERING, in a SOCIETY. It is a preliminary version, which is intended to become part of a book.

THE LOGIC OF EVERYDAY THINKING

In the following examples four languages are used simultaneously: (i) Boolean logic, (ii) German language, (iii) English language, (iv) Predicate logic. The idea is to make ‘visible’ that formal logic provides not only a very limited profit, but that the normal language can offer all what formal logic can offer, but even much more. If one keeps in mind that the ‘normal’ language is principally the meta-language for every kind of ‘special’ language then this should be no surprise.
