Questioning the meaning and nature of the universe and the living world calls upon all existing fields of research. If the answers to these metaphysical questions have not been provided in a strict sense, their deciphering is constantly updated with the various discoveries that are gradually transforming humankind's view of the surrounding environment. We are referring here to human consciousness, integrated into the world of reality and experienced as such, and not to consciousness whose normative filter, born of various beliefs, subtracts the most recent scientific advances.The relationship between the binary system and the quaternary system is at the origin of this book, which focuses on the questions: is any unit of living organisms only the result of a given programming? What then of the human being? Are they a robot participating in the living world or a consciousness inscribed in a biological habitat?
