Set Theory and Logic


Modus Inversus – if (Premise is False) Then (Conclusion is False)

Authors: Ilija Barukčić

Objective: When theorems or theories are falsified by a formal prove or by observations et cetera, authors respond many times by different and sometimes inappropriate counter-measures. Even if the pressure by which we are forced to believe in different theories although there are already predictively superior rivals to turn to may be very high, a clear scientific methodology should be able to help us to assure the demarcation between science and pseudoscience. Methods: Karl Popper’s (1902-1994) falsificationist methodology is one of the many approaches to the problem of the demarcation between scientific and non-scientific theories but relies as such too much only on modus tollens and is in fact purely one-eyed. Results: Modus inversus is illustrated in more detail in order to identify non-scientific claims as soon as possible and to help authors not to hide to long behind a lot of self-contradictory and sometimes highly abstract, even mathematical stuff. Conclusions: Modus inversus prevents us from accepting seemingly contradictory theorems or rules in science. Keywords: Science, non-science, modus inversus. E-Mail:
