A collaborative conversation between Dr. Maturana and Prof. Davila with the purpose of explaining the basis of human origins as a biological-cultural construct. They will speak about the origin of language and conversation to illustrate the type of worlds that are generated within our coexistence. A ‘circulo reflexivo’ is a space constituted by people invited to reflect upon and converse, listen to each other, have opinions on a subject, in this case cofijnspiration and collaboration as a conceptual, biological phenomenon. Dr. Maturana and Prof. Davila are the founders of Instituto Matriztico, where they develop an educational and research practice. They create learning relational spaces about our biological-cultural existence, conceived as experiential domains of reflections and interactions that evoke and realize the possibility of ethical responsibility in a world of collaborative co-existence.
