 Unlike unlimited pancomputationalism, limited pancomputationalism does not turn the claim that something is computational into a vacuous one. Different systems generally have different objective properties; thus, according to limited pancomputationalism, different systems generally perform different computations. Nevertheless, it may seem that limited pancomputationalism still trivializes the claim that a system is computational. For according to limited pancomputationalism, digital computers perform computations in the same sense in which rocks, hurricanes, and planetary systems do. This seems at odds with computer science and engineering, as well as the computational theory of cognition. If every physical process is a computation, computer science would have to include every physical process in its domain of inquiry, and the computational theory of cognition—which was motivated in part by the idea that cognition is distinctively explained by computation—loses much of its explanatory force.
