The problem of impenetrability from modern metaphysics to contemporary physics

This thesis tackles the physical and metaphysical structure and consequences of the concept of impenetrability which is thought to play a key role in understanding the structure of matter in the context of the question "what is the internal structure of matter?". In this sense, after examining how the problem of impenetrability has emerged and been addressed in modern philosophy, the study focuses particularly on the Pauli exclusion principle in the context of field theories developed within quantum mechanics. In this thesis proceeding in such a course, it is ultimately aimed to open up for discussion that there is possibility of propounding a similar one of the pure and metaphysical grounds of natural sciences, which Kant has put forward in classical mechanics, for quantum mechanics as well. Keywords: Impenetrability, Quantum Mechanics, Pauli Exclusion Principle
