Abstract
I consider how The Dawn of Everything deals with the question of whether cultural ideation can help explain social change in ways that do not posit non-material causal factors. I submit that the answer has to do with how each culture is materially impacted by other cultures, and how this leads to socio-political differentiation under similar environmental and technological conditions. In a nutshell, a culture’s ideation is a material constraint for other cultures that come into contact with it. I call this position, which I attribute to Graeber and Wengrow, intercultural materialism.
