In pursuing various lines of inquiry, I keep coming up with one name: Edgar Morin. He was born in 1921. That means he's 91. He's one of the French social philosophers who drifted away from Marxism.
One of his most important works is available in English, although very expensive.
This is the first of several volumes exposing Edgar Morin's general systems view on life and society. The present volume maintains that the organization of all life and society necessitates the simultaneous interplay of order and disorder. All systems, physical, biological, social, political and informational, incessantly reshape part and whole through feedback, thereby generating increasingly complex systems. For continued evolution, these simultaneously complementary, concurrent, and antagonistic systems require a priority of love over truth, of subject over object, of Sy-bernetics over cybernetics.
He was a founding member of the International Ethical, Scientific and Political Collegium also known as the Collegium International that published the Declaration of Interdependence in 2005. This is not to be confused with a document by the same name published in 1945 by Will Durant, among others.
