Complex Thinking is a philosophical concept created by Henri Laborit during informal Group of Ten meetings and introduced by Edgar Morin. The first formulation of complex thought dates from 1982 in the book Science avec conscience by Morin:
"The goal of method research is not to find a unitary principle of all knowledge, but to indicate the emergence of a complex thought, which cannot be reduced either to science or to philosophy, but which allows their intercommunication by operating dialogic loops 1. "
This concept expresses a form of thought accepting the interweaving of each domain of thought and transdisciplinarity. The term complexity is taken in the sense of its etymology "complexus" which means "what is woven together", in a tangle of interlacing (plexus).
