Current philosophical theorizing about technical functions is mainly focused on specifying conditions under which agents are justified in ascribing functions to technical artifacts. Yet, assessing the precise explanatory relevance of such function ascriptions is, by and large, a neglected topic in the philosophy of technical artifacts and technical functions. We assess the explanatory utility of ascriptions of technical functions in the following three explanation-seeking contexts: why was artifact x produced?, why does artifact x not have the expected capacity to ϕ?, (...) how does artifact x realize its capacity to ϕ? We argue that while function ascriptions serve a mere heuristic role in the first context, they have substantial explanatory leverage in the second and third context. In addition, we assess the relevance of function ascriptions in the context of engineering redesign. Here, function ascriptions also play a relevant role: they enable normative statements of the sort that component b functions better than component a. We unpack these claims by considering philosophical theories of technical functions, in particular the ICE theory, and engineering work on function ascription and explanation. We close the paper by relating our analysis to current debates on the explanatory power of mechanistic vis-à-vis functional explanations. (shrink)

This article presents a formal ontology which accounts for the general nature of artefacts. The objective is to help structure application ontologies in areas where specific artefacts are present - in other words, virtually any area of activity. The conceptualization relies on recent philosophical and psychological research on artefacts, having resulted in a largely consensual theoretical basis. Furthermore, this ontology of artefacts extends the foundational DOLCE ontology and supplements its axiomatization. The conceptual primitives are as follows: artificial entity, intentional production (...) of entities, (state of) capacity, capacity to play a role in actions of a given type, function and functional object. These primitives enable artefacts in general to be characterized as intentionally and successfully produced entities, and isolate an important subclass of “technical” artefacts to which a function is ascribed. Lastly, we emphasize the novelty of this ontology by comparing it with other works with similar objectives. (shrink)

This paper systematically compares two frameworks for analysing technical artefacts: the Dual-Nature approach, exemplified by the contributions to Kroes and Meijers , and the collectivist approach advocated by Schyfter , following Kusch . After describing the main tenets of both approaches, we show that there is significant overlap between them: both frameworks analyse the most typical cases of artefact use, albeit in different terms, but to largely the same extent. Then, we describe several kinds of cases for which the frameworks (...) yield different analyses. For these cases, which include one-of-a-kind artefacts and defect types, the Dual-Nature framework leads to a more attractive analysis. Our comparison also gives us the opportunity to respond to Vaesen’s critical paper. We do so by distinguishing two readings of the Dual-Nature framework and pointing out that on the sustainable, weaker reading, Vaesen’s considerations supplement the framework rather than offering an alternative to it.Keywords: Technical artefact; Dual Nature framework; Collectivist framework; Artefact use.
