This document discusses autopoietic theory, which defines life as self-creation. It summarizes that autopoietic systems are:
1) Energetically open and able to exchange matter and energy with the environment while maintaining a bounded structure.
2) Self-referential, with internal communication determining coordination and behavior without a nervous system.
3) Structure-determined, with structural changes triggered but not determined by the environment.
It implies cognition is a biological phenomenon and information does not exist independently of a system. Communication coordinates behavior through recursive processes of distinction and coordination of actions.
