 It is important to note that under all of these mapping accounts, there are mappings between any physical system and at least some computational descriptions. Thus, according to mapping accounts, everything performs at least some computations (cf. Section 3.2). This strikes some as overly inclusive. In computer science and cognitive science, there seems to be a distinction between systems that compute and systems that do not. To preserve this distinction, one option is to move beyond mapping accounts of implementation.
