The mechanists’ emphasis on mechanistic/organizational and epistemic emergence contrasts with their desire to distance themselves from spooky emergence (Richardson and Stephan 2007). Spooky emergence would involve the appearance of new properties with no sufficient basis in mechanisms. It is not clear that emergent properties are properly said to be properties of the necessary mechanisms; and it is not clear in what since the emergent property is “emergent” rather than a fundamental feature of the causal structure of the world.
