In this paper we examine the possibilities of combining two central intuitions about artefacts: that they are functional objects, and that they are non-natural objects. We do so in four steps. First we argue that, contrary to common opinion, functions cannot be the cornerstone of a characterisation of artefacts. Our argument suggests an alternative view, which characterises artefacts as objects embedded in what we call use plans. Second, we show that this plan-centred successor of the function-focused view is at odds with the non-naturalness intuition. Third, we show that this intuition can be developed by defining artefacts as produced or human-made objects, but that the resulting definition might collapse into the plan-centred view, and has trouble distinguishing artefact types or kinds. Finally, we propose a division of labour between production and use plans: among objects in general, artefacts are distinguished as human-made objects; within the domain of artefacts, types or kinds are characterised by the use plans in which artefacts are embedded.

In this paper, it is examined to what extent functions, as analysed in the philosophy of technical artefacts, can serve a role in explaining the aesthetic appreciation of these objects. The main conclusion is that, despite first appearances, so-called ‘Functional Beauty’ accounts cannot derive strength from analyses of artefact functions; on the contrary, these analyses constrain the possibilities for developing a suitable, function-based account of aesthetic appreciation. The paper follows a conceptual-engineering approach. After presenting desiderata for an account of aesthetic appreciation, relevant insights are reviewed that are drawn from philosophical work on artefact functions. Combining the desiderata and insights, three major issues are identified that complicate the relation between function ascriptions to and aesthetic appreciation of technical artefacts. In closing, options are offered for resolving these complications or avoiding them altogether.

The philosophy of artifacts is as marginal as it is one-sided. The majority of contributions to it are asides in works devoted to other subjects and focus on one characteristic feature: that artifacts are objects with functions. Indeed many artifacts, such as screwdrivers and toasters, come in functional kinds. Perhaps for this reason, philosophers elevated functions to the essences of artifacts or have developed general theories of function to describe artifacts along with their main subject: biological items. Most such theories present one monolithic notion of function that applies to both. Dissident voices claim autonomy for artifact functions, or at least a small measure of conceptual independence, but it is seldom questioned that a theory of artifacts consists merely of a theory of artifact functions.

Scientific disagreements sometimes persist even if scientists fully share results of their research. In this paper we develop an agent-based model to study the impact of diverging diagnostic values scientists may assign to the evidence, given their different background assumptions, on the emergence of polarization in the scientific community. Scientists are represented as Bayesian updaters for whom the diagnosticity of evidence is given by the Bayes factor. Our results suggest that an initial disagreement on the diagnostic value of evidence can, but does not necessarily, lead to polarization, depending on the sample size of the performed studies and the confidence interval within which scientists share their opinions. In particular, the more data scientists share,the more likely it is that the community will end up polarized.

The notion of template has recently been discussed in relation to cross-disciplinary transfer of modeling efforts and in relation to the representational content of models. We further develop and disambiguate the notion of template and find that, suitably developed, it is useful in distinguishing and analyzing different types of transfer, none of which supports a non-representationalist view of models. We illustrate our main findings with the modeling of technology substitution with Lotka-Volterra Competition equations.

In this paper we use our work in the philosophy of technology to formulate a pluralist view on artefact categories and categorisation principles, as studied in cognitive science. We argue, on the basis of classifications derived by philosophical reconstruction, that artefacts can be clustered in more than one way, and that each clustering may be taken as defining psychological artefact categories. We contrast this pluralism with essentialism and super-minimalism on artefact categories and we argue that pluralism is coherent with experimental results regarding the context-dependence of artefact categorisation

In this paper we present an action-theoretic account of artefact using and designing and describe our ICE-theory of function ascriptions to technical artefacts. By means of this account and theory we analyse the thesis of the dual nature of technical artefacts according to which descriptions of technical artefacts draw on structural and intentional conceptualisations. We show that the ascription of technical functions to technical artefacts can connect the intentional and structural parts of descriptions of artefacts, but also separate these parts. Our conclusion is that the concept of technical functions forms a ‘conceptual drawbridge’ between the intentional and structural natures of technical artefacts.Keywords: Intentional and structural descriptions; Technical artefacts; Function theory; Action theory; Use; Design

The aim of this paper is to evaluate etiological accounts of functions for the domain of technical artefacts. Etiological theories ascribe functions to items on the basis of the causal histories of those items; they apply relatively straightforwardly to the biological domain, in which neo-Darwinian evolutionary theory provides a well-developed and generally accepted background for describing the causal histories of biological items. Yet there is no well-developed and generally accepted theory for describing the causal history of artefacts, so the application of etiological theories to the technical domain is hardly straightforward. In this paper we consider the transposition of etiological theories in general from the biological to the technical domain. We argue that a number of etiological theories that appear defensible for biology become untenable for technology. We illustrate our argument by showing that the standard etiological accounts of Neander and Millikan, and some recent attempts to improve on them, provide examples of such untenable theories. 1 Introduction 2 Desiderata for theories of functions 3 Etiological theories in general 3.1 Common core and divergent aims 3.2 Reproduction versus non-reproduction etiological theories 3.3 Intentionalist versus non-intentionalist etiological theories 4 Problems for etiological theories in the technical domain 5 The failure of existing reproduction theories 6 The failure of existing non-reproduction theories 7 Improving reproduction by hybridisation 8 Conclusions.

In this paper, I study the application of phylogenetic analysis in evolutionary archaeology. I show how transfer of this apparently general analytic tool is affected by salient differences in disciplinary context. One is that archaeologists, unlike many biologists, do not regard cladistics as a tool for classification, but are primarily interested in explanation. The other is that explanation is traditionally sought in terms of individual-level rather than population-level mechanisms. The latter disciplinary difference creates an ambiguity in the application and interpretation of phylogenetic analyses. Moreover, I argue that, while archaeologists have claimed that “cladistics is useful for reconstructing artefact phylogenies”, these reconstructions only contribute minimally to the explanatory research agenda of evolutionary archaeology
