Reflections on Autopoiesis, the Signature of Life

I agree with Capra that autopoiesis is the signature of life and that Maturana did well to reject Cartesian dualism. Contrary to how mainstream biology defines life, I point out that reproduction is a consequence of life, not its origin. Furthermore, I address the questions of whether both autopoiesis and cognition together are necessary for life and whether autopoiesis can be extended beyond the molecular domain. I also have words of criticism for Maturana, who called for "objectivity" to be put in parentheses, and conclude with a reminder that it was Varela who was instrumental in making autopoiesis a household term.
