In his book 'The Burnout Society,' Byung-Chul Han presents the paradigm shift that has led humanity from a disciplinary society to a performance society. From a repressive society, based on the negativity of prohibitions, to a hyperactive society, overflowing with stimuli and information, based on total positivity. The verb that defines the performance society is not 'must' but 'can'; modern man believes himself to be free, but paradoxically lives at war with himself. The performance society, Han says, engenders the endless pain of self-exhaustion.
