Every society in the history of humanity has lived with religion. In How Religion Evolved, evolutionary psychologist Professor Robin Dunbar tracks its origins back to what he terms the 'mystical stance' - the aspect of human psychology that predisposes us to believe in a transcendent world. Dunbar argues that this instinct is not a peculiar human quirk, an aberration on our otherwise efficient evolutionary journey. Rather, religion confers an advantage: it can benefit our individual health and wellbeing, but, more importantly, it fosters social bonding at large scale, helping hold fractious societies together. Drawing on path-breaking research, clinical case studies and fieldwork from around the globe, as well as stories of charismatic cult leaders, mysterious sects and lost faiths, How Religion Evolved offers a fascinating and far-reaching analysis of this quintessentially human impulse - to believe.
