The book begins with the body as the foundation of perception, cognition, and ethics, affirming that all meanings of life are tied to the finitude, fragility, and self-regulation of the living system. Man is not an entity separate from nature or matter, but a highly organized material structure in which biology, perception, and consciousness are intertwined in a continuous dynamic system. In this structure, the boundary between the inside and the outside, between the finite and the possible, between life and death, creates the conditions for freedom and responsibility to emerge. The book analyzes the foundations of life, such as the boundaries of existence, the spatial and temporal coordinate system of meaning, the structure of limits, and the relationship between organic and material of the universe. The work aims at a deeper understanding of humanity in the technological age, where human dignity lies not in transcending limits but in the ability to live, create, and take responsibility within those very limits.
