The Law of Religion

Core idea

Religion, for Harari, is any system of norms and values founded on a belief in a superhuman order. By that definition it includes monotheisms and polytheisms but also dualist faiths like Zoroastrianism and Manichaeism — and modern "natural-law" religions such as liberal humanism, communism, and Nazism, which appeal not to gods but to an absolute moral order they claim is built into nature. Religion is the third universal order: alongside money and empire, it gave large fragile societies a superhuman warrant for their otherwise arbitrary laws.

Why it matters

If your working definition of religion stops at "belief in God," you miss the most ideologically powerful belief systems of the last two centuries. Harari's expanded category lets you see liberal democracy, capitalism, and human rights as religions in everything but name — comprehensive worldviews with absolute commandments, sacred texts, heretics, and missionaries. That shift is uncomfortable, and intentionally so.

Practical application

Apply Harari's two-part test

When asked whether something — yoga, communism, market fundamentalism, AI alignment — is a religion, run the test: (1) does it appeal to a superhuman order its adherents did not invent, and (2) does it derive binding norms from that order? If both are true, treat it as a religion regardless of its self-description. The behavioural signatures (heresy, schism, martyrdom, missionaries) will usually confirm the diagnosis.

Watch how empires pick religions for unification

Constantine did not adopt Christianity for theological elegance; he adopted it because a universal-missionary religion could glue together an empire of disparate peoples. Whenever a state, corporation, or movement reaches for a "shared story" to unify a heterogeneous group, ask whether it is selecting on truth or on universality and missionary energy — these are almost orthogonal criteria.

Example

Consider liberal humanism, the unofficial religion of modern Western democracies. Its superhuman order is "the sanctity of the individual"; its commandments are codified in human-rights charters; its heretics are dehumanisers and authoritarians; its missionaries are NGOs and diplomats. No god is invoked, yet violating its core tenets — slavery, torture, denial of citizenship — produces moral horror as visceral as any blasphemy in a theist faith. Harari's point is not that humanism is false but that its psychological structure is precisely that of a religion, and its claims about "natural" rights are as historically contingent as any creation myth.
