Sapiens: A Brief History of Humankind

Religion can thus be defined as a system of human norms and values that is founded on a belief in a superhuman order. This involves two distinct criteria: 1. Religion is an entire system of norms and values, rather than an isolated custom or belief. Knocking on wood for good luck isn’t a religion. Even a belief in reincarnation does not constitute a religion, as long as it does not validate certain behavioral standards. 2. To be considered a religion, the system of norms and values must claim to be based on superhuman laws rather than on human decisions. Professional soccer is not a religion, because despite its many rules, rites and often bizarre rituals, everyone knows that human beings invented soccer themselves, and FIFA may at any moment enlarge the size of the goal or cancel the offside rule.
