This is the second essay about Edgar Morin’s brief “Homeland Earth” book and part of a series of essays on The Predicament and Hope of Mankind.
The Planetary Era began when humanity started to discover our round planet, a tiny part of the solar system and the rest of the cosmos; and simultaneously, when disperse civilizations began to communicate with each other on a global basis. This chapter of the book describes in 25 pages this seven centuries adventure until 1992 - an adventure framed by colonialism, independence, wars, industrialism, the birth of the nation state...; and also framed by the gradual emergence of a planetary consciousness as humanity’s history oscillates between integration and autonomy of people and societies. I add some notes to update this history until 2013.
