This text explores the philosophical and biological concepts of evolution, rejecting both strict determinism and pure contingency. The author posits that the emergence of the "new" is an organized process resulting from the encounter between material and structure, guided by central organs that operate with inherent meaning and purpose. Freedom is redefined not as mere indeterminacy, but as the capacity to manage situations progressively and planfully. The second part of the document draws on the theories of Hans Petersen and Jakob von Uexküll, introducing the concept of the "Eigenwelt" (own-world) or "Umwelt." An organism is defined by its receptors and effectors, which establish functional circles and a specific sphere of meaning. Life is viewed as an integral part of a biocoenosis, where individual life plans and environments are interconnected within a complex cosmic web governed by an internal "life melody." Ultimately, the text asserts that development is not a series of random accidents but a structured differentiation and organization of reality.
