According to the definition of consciousness that is dominant in contemporary analytic philosophy, something is conscious just in case there is something that it’s like to be it; that is to say, if it has some kind of experience, no matter how basic.[7] Humans have incredibly rich and complex experience, horses less so, mice less so again. Standardly the panexperientialist holds that this diminishing of the complexity of experience continues down through plants, and through to the basic constituents of reality, perhaps electrons and quarks. If the notion of “having experience” is flexible enough, then the view that an electron has experience—of some extremely basic kind—would seem to be coherent (of course we must distinguish the question of whether it is coherent from the question of whether it is plausible; the latter will depend on the strength of the arguments discussed below).
