Abstract

This paper offers a pragmatist interpretation of Ian Hacking’s version of entity realism, and shows that such an interpretation enables the view to withstand a number of objections. Specifically, the paper shows Hacking’s rejection of a representationalist epistemology, which realist critics unjustifiably attribute to him, and shows his endorsement of a Deweyan pragmatist epistemology instead. If the interpretation is correct, the objections (a) that entity manipulation is theory-laden, (b) that the concept of home truths cannot do the work Hacking envisioned, (c) that entity realism is a form of inference to the best explanation (IBE), (d) that some real entities aren’t manipulable, and (e) that some non-real entities are manipulable, lose much of their force. Objections (a), (b), and (c) rest on a metaepistemological misunderstanding, while objections (d) and (e) are addressed with (pragmatist) clarifications. This paper also offers a novel pragmatist argument for entity realism: the argument from technology. The argument from technology maintains that the reality of the entities that constitute our technologies is a precondition for those technologies’ meaningful use. In this case, entity realism remains a more viable perspective on science than is commonly acknowledged.
