No chimpanzee cares about the interests of the chimpanzee species, no snail will lift a tentacle for the global snail community, no lion alpha male makes a bid for becoming the king of all lions, and at the entrance of no beehive can one find the slogan: ‘Worker bees of the world – unite!’ But beginning with the Cognitive Revolution, Homo sapiens became more and more exceptional in this respect. People began to cooperate on a regular basis with complete strangers, whom they imagined as ‘brothers’ or ‘friends’.
