Bio Note: Born in Chile in 1928, Humberto Maturana Romesín was interested in animals and plants from childhood and wanted to be a biologist to investigate life that dies. A long period of reflection, reading Frederic Nietzsche and Julian Huxley, occurred during three years of complete bed rest.Beginning medicine in 1950, in1958 he received a Ph.D. in Biology from Harvard University. His main contributions in biology related to showing that living beings are molecular autopoietic systems, and that if one follows the consequences of the fact that living beings do not distinguish in their experience between perception and illusion, one can show that: language as a biological phenomenon occurs as a flow of living together in coordinations of coordinations of consensual behaviors; and cognition as a biological phenomenon occurs when an organism operates adequately to the circumstances of its living, conserving its autopoiesis as a consequence of the operational-relational coherences with its niche that are proper to it in the present of its living as a feature of the history of evolutionary structural drift to which it belongs. Maturana passed away on 6 May 2021.
