 Another purported source of pancomputationalism is that computation is simply the causal or dynamical structure of physical processes, as the causal account of computation (Section 2.2) maintains (Chrisley 1995, Chalmers 1995, 1996, Scheutz 1999, 2001). Assuming that everything has causal structure, it follows that everything performs the computation constituted by its causal structure. This may be called causal pancomputationalism.
