TRADITIONAL METAPHYSICS AND QUANTUM MECHANICS
The paper shows how the principles of traditional metaphysics are used for the interpretation of quantum mechanics. Proceeding from the triad of the key concepts «necessary - possible -actual» it is possible to interpret all the complex issues of the quantum theory, first of all, the problem of reality and causality. The paper for the first time provides the solutions of the «secrets» of quantum mechanics (R. Feynman).
