The present work contains a proposal for a foundation of elementary, fundamental terms within philosophy and science, to be built from modal operators. With their help, it will be possible to shed new light on numerous basic problems of modal logic, of the theory of probability, of mathematics, of quantum physics, and of the theory of time. The author, in her decades-long, self-taught course of study, has attempted to take up the weaknesses in expositions related to the basic themes named above, expositions with Aristotle, Frege, Russell, Heisenberg and many others. Furthermore, the author has sought to rectify these weaknesses using her sketch of a constitutional system.With that, the following points are worth noting: - Inconsistencies have been discovered in the definitions (which inform all significant logicians) in the Aristotelian tables of implications regarding modal terms (8); - The system endeavours, with the aid of the modal theoretical definition of unit, to bolster Frege's critique of the current definition of unit (10); - Using the modal theoretical definitions of the point, the thesis makes it possible to eliminate the obvious contradictions in the constructions of the continuum (15) and the theory of time (16); and finally, - The concept of actuality, as derived from the complementarity of necessity and possibility, can offer numerous quantum theorists a plausible explanation for their statements about strings and their properties (14.
6). Helga Haase delivers answers to these and similar questions with her building blocks to overcome the separation between Human Sciences and Natural Science. The author develops objectively scientifically and understandably a new system of categories apt for both in order to solve the ancient problem created by Descartes: the polarization of research into human and natural sciences.
