This book provides ways to implement thoughts from the world of ideas in the material world. Questions about the self-awareness of man as a biosocial being are briefly discussed, answers to the questions: “Who is a person?”, “What is happiness and success?” - in the light of neurophysiology, biological processes and social society. If we proceed from Marxist philosophy, then we can argue that the process of scientific knowledge is a movement from living contemplation to science and back from it to practice. A person begins studying the world from the environment initially in order to satisfy his needs, and questions about studying himself mature later , which became subjects of discussion in religion, philosophy, psychology, and subsequently in the fundamental sciences.
