The famous German doctor, psychologist and thinker of the late 19th and early 20th centuries, Wilhelm Wundt, who is called one of the founders of modern psychology, wrote a colossal number of works in various fields of philosophy during his more than 60 years of scientific activity. Here is a collection of articles devoted to Wundt’s study of the essence of metaphysics, the various stages of its development and reflections on its future. In the second part of the book, the author discusses the physiology of the human brain and its connection with spiritual activity. Is it possible for metaphysics to exist as a science? What is the content of our spiritual life? How to find harmony with spiritual existence? This book aims to answer these and other questions.
