摘要：By closely observing reality,on the level of either the primary natural products (living organisms) or the derivatives thereof (society, reasoning),we notice that nothing exists without antecedent and devoid of certain connection with the environment. Then, we may understand that,regardless of their rank, the elements collaboratively correlate with each other, differ from one another and hierarchize among themselves forming structurally and functionally unitary systems that are able to co-evolve on ontogenetic and phylogenetic levels.The functioning of the elements within the system, in its turn, has to meet both the requirements of interacting with the environment and the functional-organizational needs of the system itself.
