Physical causal closure is a metaphysical theory about the nature of causation in the physical realm with significant ramifications in the study of metaphysics and the mind. In a strongly stated version, physical causal closure says that "all physical states have pure physical causes" — Jaegwon Kim, or that "physical effects have only physical causes" — Agustin Vincente, p. 150. Those who accept the theory tend, in general although not exclusively, to the physicalist view th… msnbc host joe scarboroughWebThe quantum fluctuations that create Quarks have always been happening. the universe is a closed system.
