Communautics and Sociotics at the heart of human development! The work opens on a new way of reading collective dynamics and the aggregation of ideas (ecology of ideas).

Any work of general interest requiring for its accomplishment a minimum of egoism and a maximum of blind devotion, abnegation and sacrifice, can hardly be accomplished except by the crowds. Gustave Le Bon
