The Causal Closure of Physics in Real World Contexts	2020-08-18		.txt	text/plain	15740	965	60	Secondly, I show that causal closure in the hierarchy of emergence is a strictly interlevel affair, and in the cases of engineering and biology encompasses all levels from the social level to the particle physics level. In particular, the particle physics level is not causally complete by itself in the contexts of solid state physics (because of interlevel wave–particle duality), digital computers (where algorithms determine outcomes), or biology (because of time dependent constraints). Here I want to examine the issue in a different way, by dealing in some detail with the hierarchical nature of emergence in real world contexts: the cases of engineering, based in the underlying solid state physics, and biology, based in the underlying molecular biology, in turn based in the underlying physics. Effective Causal Closure in real world contexts spans many levels, in the case of biology reaching down from the level of the organism to the underlying physics via time dependent constraints.	./cache/cord-349831-0u9y35qo.txt	./txt/cord-349831-0u9y35qo.txt
