Creators offload the construction of their artifact in that the world helps to determine the nature of their imposition in ways that can go beyond the content of their imposing activities. Extant theories of imposition fail to account for offloading by requiring match between content and product. Therefore, I develop an externalist theory that accommodates offloading by taking the imposition of mind onto world to be objectively constrained. An important kind of imposition is normativity. Focusing on personal value, what’s valuable (...) for someone is determined by what they value as good or bad for themselves. Such a subjectivist view faces the same problem as extant theories of imposition in seeming to preclude the possibility of making mistakes about value. Applying imposition externalism, I defend an artifactual approach to subjectivism such that mistakes are captured in terms of offloading. A subject’s valuing can fail to match the very value it creates. (shrink)
