The mathematical justification of quantum mechanics from a philosophical point of view. 2nd edition, supplemented.

This book considers the classical rationalistic concept of substantiating scientific knowledge (Descartes, Leibniz, Kant, Husserl). The author proves that although today it is often interpreted as outdated, it can be developed taking into account the results of modern natural science. The modern concepts of the substantiation of scientific knowledge are analyzed, the evolution of the foundations of quantum theory is investigated.

The book is intended for all readers interested in the issues of philosophy, methodology and history of science.
