The culture broth according to Edgar Morin and its composition in the OHMs. 1. Through ‘heat activation’, the development of dialogical exchanges leads to a weakening of determinisms, which makes transgression and deviance possible. Improbable encounters can then occur, favouring serendipity, emergence and innovation, with the hybridization and synthesis of opposites, eminently dialogical situations, and the like. This conception, which comes straight from Les Idées, has been directly applied to the modus operandi of the OHMs, term for term (2), with the implementation of the operating modes presented (diversity, specific opportunities to meet, attitudes during interactions, etc.). For the OHMs, the circle is based on annual activities (source: R. Chenorkian).
