About the book: 1989 / “Who are we? Where? Why?..” Perhaps there is no person who would not more or less consciously and for a long time strive to get answers to these questions and thereby get to know himself better. To date, science has accumulated a huge amount of data, thousands of diverse concepts have been formulated, but the essence of man as an amazing complex phenomenon of Nature remains unknown. The author proposes to use a postulative approach to build one of the possible options for an integral system of concepts in the human sciences. The work, thanks to the high compression of scientific information, uses the latest data from a wide cross-section of sciences from the fundamental physical principles of matter to the phenomenon of “ideal” in the psyche. The book can be useful to specialists dealing with human problems, it will be of interest to any reader who is concerned about the world’s mysteries of Nature, search for the meaning of life.
