According to Wright's theory, although religion may seem otherworldly-a realm of revelation and spirituality-its history has, like that of much else, been driven by mundane "facts on the ground." Religion, that is, changes through time primarily because it responds to changing circumstances in the real world: economics, politics, and war. Wright thus offers what he emphasizes is a materialist account of religion. As he further emphasizes, the ways in which religion responds to the world make sense. Like organisms, religions respond adaptively to the world.
