Abstract

This paper presents a novel theory of artifact functions, drawing from persistence-based accounts of social functions, according to which the function of an artifact consists in those of its effects that contribute to the persistence of its kind. First, the paper argues that artifact functions have an underacknowledged “interventionist task”: functional ascriptions have implications for the ways that users have reason to use technologies, and how they have reason to intervene when technologies have undesired effects. Then, it argues that the ways that users have reason to use technologies and intervene are informed by the present persistence conditions of artifact kinds. It is therefore useful to incorporate these persistence conditions into the artifacts’ functions. By focusing on the social and political embedding of artifacts, the theory also allows for fruitful connections between the theory of artifacts, the political philosophy of technology, and the literature on functions in the philosophy of social science.

Notes

  1. Likewise, Houkes and Vermaas (2010) describe their view as a “function-ascription formulation” rather than a “function-as-property formulation” (p. 78).

  2. Relatedly, Norman (2013) suggests principles of design that are meant to help users infer correct use as easily as possible. See also Davis (2020).

  3. I owe this example to an anonymous reviewer.

  4. Or, failures to produce desired effects. I take these to be two sides of the same coin and use them interchangeably.

  5. This may mean that the effect itself is a part of the artifact’s function, or that it’s not a part of the function but is nevertheless compatible with the function. In either case, intervening would not mean making the artifact better at its current function.

  6. While the focus of the present paper is the functions of artifacts, interventionist normativity appears in a variety of contexts. For example, Justin Garson (2010, 2022) has argued for the importance of disciplined use of function talk in psychiatry. Mental disorders are often described as dysfunctions in the sense that they have maladaptive effects. However, some mental disorders may also have (either direct or derived) proper functions based on selected effects. Because dysfunction suggests a need to restore an original or natural state of working order, describing mental disorders as dysfunctional distorts the goal of treatment. Here, too, function talk can be evaluated by the usefulness of its prescriptions for intervention.

  7. The “prima facie” here is important. Ultimately, I accept a pluralistic approach to artifact functions (see Perlman, 2009). Such an approach seems necessary, as different accounts of artifact functions seem to be meant to perform different kinds of descriptive and explanatory work. My point is simply that informing interventions is one type of work that the notion of function performs.

  8. This is noteworthy because social entities, like artifacts, often have both intentional design and histories of selection. Nevertheless, these are not typically taken to exhaust their functions.

  9. I borrow this terminology from Franssen (2006), though it is somewhat non-standard. In analytic metaphysics, kinds are typically said to have members, while types have tokens. However, Franssen uses artifact “kind” as a technical term, which he describes as a variety of artifact “type” (though Franssen also makes use of a narrower notion of artifact type) (p. 48). Thus, kinds have tokens, for Franssen, because they are a type in the sense typically used in metaphysics.

  10. In more distant possible worlds in which cellphones persist but do not depend on providing profit to companies to do so, they might have different persistence conditions. Because the view under consideration defines functions—and in turn artifact kinds—by their effects that promote their persistence under present selection pressures, cellphones in these possible worlds would have a different function and therefore be a different kind of artifact than cellphones in the present.

  11. Whether or to what extent it is the case that the app’s persistence was conditioned on its producing these effects is an empirical question for social scientists. The point of the present paper is that the functions of artifacts depend on such counterfactuals in this way.

  12. There might, nevertheless, be fine-grained distinctions within kinds. Wooden and metal spoons share some persistence conditions, and don’t share others. This is true on other accounts as well, however (see Franssen, 2006 on types and kinds).
