The probabilistic nature of quantum mechanics is determined by peculiar mathematics which can only describe the quantum phenomena – this mathematics gives statistical explanations to these phenomena and no other explanations could in principle be given to them; as well, the phenomena of classical physics which are to be described definitely (but not in principle probabilistically) can be described this way only because, in its turn, it is determined by peculiar mathematics and – as it is argued in the book – this simple mathematics can be straightforwardly inferred from the special relativity theory.

It is shown that these important results correspond to the approach accepted in modern physics due, in particular, to Bell’s inequalities and their tests. However, the author concentrates on the philosophical consequences that should be inferred from these physical results. Naturally, metaphysical views which can be congenial to this kind of physical picture of the world must agree with the concept of non-homogeneity. Such metaphysics was firstly exposed by the author in his work devoted to the non-linearity of natural language: The World and Language: The Ontology for Natural Language (Lanham: University Press of America, 2006). But one does not need to be familiar with this book in order to read Physics and Metaphysics; nor is it necessary for the reader to have any mathematical skill or serious knowledge in physics. This book will be of benefit to those interested in the fields of physics, quantum mechanics and mathematics.
