ZusammenfassungDie klassische Aussagenlogik wird falsch gedeutet. Korrigiert man die Deutungen, dann ist sie eine epistemische Möglichkeitenlogik, die sich aus assertorischen und kon‐tingenten Aussagen zusammensetzt. Da sie nicht modalitatenneutral ist, dürfen andere Logiken nicht auf ihr ohne diese Einschrankung aufbauen. Sie bedarf zur sinnvollen Deutung einer handlungstheoretischen Einbettung und ist insofern selbst schon ein Stück pragmatische Logik. Der Gebrauch der Negation dyadischer Aussagen beruht auf einer willkürlichen Festlegung, die durch die Abstraktion vom epistemisch‐hand‐lungstheoretischen Zusammenhang ermöglicht wird.

Summary Not ‘human sciences’, but physics is said to be the measure for that what is called science . Deficiencies of human sciences are led back to complexity, external influences etc. If one differentiates several orientations for that what is called science , another reason is determinable. The conceptions of science in modern thinking are monistically orientated, because they have the aim to reach exceptional knowledge, that lets eliminate alternatives. Elimination combined with competition leads to prejudices. Competition does not reduce (...) the irrationality, like Popper, Toulmin and others assumed, but further it. Only a polyistic orientation, for which the aim of science would be the making and maintenance of alternatives, would diminish the causes for prejudices. Since in the ‘human sciences’ unlike natural sciences prejudices are objects of research this leads to a weakening of the object orientated elimination. What therefore has become an ideal for physics, has fatal consequences for ‘human sciences’, which a physics orientated philosophy of science consolidates. For that reason a polyistic orientated understanding of science has to be developed, that can be divided in eclectic (pluralistic) and systematic conceptions. As an intensional combinatorics produces systematically alternatives systematic polyism and combinatorics are connected with each other. (shrink)
