Humberto Maturana’s work explores the biological foundations of cognition, arguing that living beings are structure-determined systems that do not represent an external world but rather “bring forth” reality through their actions. He distinguishes between two primary epistemological stances: objectivity-without-parenthesis, which assumes an independent, universal reality, and objectivity-in-parenthesis, where the observer acknowledges that reality is a multifaceted construct of their own biological and linguistic operations. Central to this theory is the concept of languaging, a recursive coordination of actions inextricably braided with emotioning, which serves as the true basis for human rationality and social systems. Within these social domains, mutual acceptance and love are identified as the constitutive biological emotions that allow for ethical coexistence and the stability of human communities. Ultimately, Maturana posits that knowing is doing, suggesting that our experience of the world is a direct reflection of our biological realisation as living entities.
