New technologies have the potential to severely “challenge” or “disrupt” not only our established social practices but our most fundamental concepts and distinctions like person versus object, nature versus artificial or being dead versus being alive. But does this disruption also change these concepts? Or does it merely change our operationalizations and applications of the same concepts? In this paper, I argue that instead of focusing on individual conceptual change, philosophers of socially disruptive technologies (SDTs) should think about conceptual change (...) as a change in a network of interrelated concepts. What really generates a potential social disruption are changes of inferential relations between concepts – whether or not this entails a change of the respective individual concepts. Philosophers of socially disruptive technologies are therefore in the privileged position of being able to avoid commitments regarding the individuation of individual concepts. -/- . (shrink)

I discuss Edouard Machery’s claim that philosophers and psychologists when using the term ‘concept’ are really theorizing about different things. This view is not new, but it has never been developed or defended in detail. Once spelled out, we can see that Machery is right that the psychological literature uses a different notion of concept. However, Machery fails to acknowledge that the two notions are not only compatible but complementary. This fits more with the traditional view according to which philosophers (...) and psychologists are merely interested in different aspects of the same kind. The main aim of this paper is then to show how precisely the two notions of ‘concept’ relate. Distinguishing them resolves the long-standing debate on whether concepts can be prototypes and allows me to formulate success conditions of a theory of categorization that are independent of the success conditions of a theory of concepts.

Polysemy has only recently entered the debate on semantic minimalism and contextualism. This is surprising considering that the key linguistic examples discussed in the debate, such as ‘John cut the grass’ or ‘The leaf is green’ appear to be prime examples of polysemy. Moreover, François Recanati recently argued that the mere existence of polysemy falsi!es semantic minimalism and supports radical contextualism. The aim of this paper is to discuss how the minimalism-contextualism debate relates to polysemy. This connection turns out to (...) be far from clear-cut. This is partly due to the fact that the term ‘polysemy’ is used in a number of different ways in the literature, which will be reviewed in this paper. Finally, I discuss and reject Recanati’s claim that the existence of polysemy supports radical contextualism against moderate versions and semantic minimalism. I show that minimalism has a number of plausible options to account for polysemy. (shrink)

It is largely assumed that conceptual engineering is essentially about revising, introducing, or eliminating representational devices, in particular the intension and extension of words and concepts. However, tying conceptual engineering too closely to representations is risky. Not everyone endorses the notion of representation as theoretically helpful or even real. Not everyone thinks that concepts or meanings should be understood in terms of the notion of representation. Does this mean that conceptual engineering is not interesting or relevant for these skeptics? In (...) this paper, I motivate and propose a non-representationalist construal of conceptual engineering. I argue that conceptual engineers can be understood as primarily engineering linguistic entitlements and commitments rather than representational devices. Note that this account is non-representationalist, but explicitly not anti-representationalist. Representations may play a significant role when it comes to justifying and completing commitment engineering projects. (shrink)

Recent evidence suggests that participants without extensive training in philosophy (so-called lay people) have difficulties responding consistently when confronted with Robert Nozick’s Experience Machine thought experiment. For example, some of the participants who reject the experience machine for themselves would still advise a stranger to enter the machine permanently. This and similar findings have been interpreted as evidence for implicit biases that prevent lay people from making rational decisions about whether the experience machine is preferable to real life, which might (...) have consequences for one of the strongest objections to philosophical hedonism (the view that pleasure is the only intrinsic value). Against this consequence, it has been argued that expert philosophers are immune to such biases (the so-called expertise defense). In this paper, I report empirical evidence against this expertise defense. (shrink)

Several authors in psychology and philosophy have recently raised the following question: when is it permissible to intentionally change the meaning and use of our words and concepts? I argue that an arguably prior question has received much less attention: Even if there were good moral or epistemic reasons for conceptual or semantic changes, this does not yet justify pushing or lobbying for such changes if they are socially and conceptually disruptive. In this paper, I develop the beginnings of an (...) ethics of conceptual disruption as well as a set of norms of linguistic interventions based on it. (shrink)

Cognitive Science, Volume 46, Issue 5, May 2022.

According to predictive processing, an increasingly influential paradigm in cognitive science, the function of the brain is to minimize the prediction error of its sensory input. Conceptual engineering is the practice of assessing and changing concepts or word meanings. We contribute to both strands of research by proposing the first cognitive account of conceptual engineering, using the predictive processing framework. Our model reveals a new kind of implementation problem as prediction errors are only minimized if enough agents embrace conceptual changes. (...) This problem can be overcome by emphasizing the importance ofsocial normsandconceptual pluralism. (shrink)

There are two general views that social ontologists currently defend concerning the nature of joint intentional action. According to ‘non-normativists’, for a joint action to be established, we need to align certain psychological states in certain ways. ‘Normativists’ argue that joint action essentially involves normative relations that cannot be reduced to the intentional states of individuals. In two ground-breaking publications, Javier Gomez-Lavin and Matthew Rachar empirically investigate the relation between normativity and joint action in several survey studies. They argue that (...) people's intuitions support neither current normativists nor current non-normativists. They suggest that there is a need for a ‘new normativism of joint action’. I first explore what a new normativism could amount to and conclude that the authors’ findings cannot support a demand for such a view. Finally, I suggest some ideas about how to move the field forward. (shrink)

In psycholinguistics, concepts are considered abstract if they do not apply to physical objects that we can touch, see, feel, hear, smell or taste. Psychologists usually distinguish concrete from abstract concepts by means of so-called _concreteness ratings_. In concreteness rating studies, laypeople are asked to rate the concreteness of words based on the above criterion. The wide use of concreteness ratings motivates an assessment of them. I point out two problems: First, most current concreteness ratings test the intuited concreteness of (...) word forms as opposed to concepts. This ignores the ubiquitous phenomenon of lexical ambiguity. Second, the criterion of abstract concepts that the instruction texts of rating studies rely on does not capture the notion that psychologists working on abstract concepts are normally interested in, i.e., concepts that could reasonably be sensorimotor representations. For many concepts that pick out physical objects, this is not reasonable. In this paper, I propose a characterization of concrete and abstract concepts that avoids these two problems and that may be useful for future studies in psychology. (shrink)

Invariantists argue that the notion of concept in psychology should be reserved for knowledge that is retrieved in a context-insensitive manner. Contextualists argue that concepts are to be understood in terms of context-sensitive ad hoc constructions. I review the central empirical evidence for and against both views and show that their conclusions are based on a common mischaracterization of both theories. When the difference between contextualism and invariantism is properly understood, it becomes apparent that the way the question of stability (...) is currently investigated will not lead to a consensus. Instead of focusing directly on stability, we should turn our attention to other desiderata on a theory of concepts. In particular, I show that invariantism, but not contextualism, fails to account for compositionality and abstract concepts. (shrink)

An explanation of how we acquire concepts of kinds if they are socially constructed is a desideratum both for a successful account of concept acquisition and a successful account of social constructionism. Both face the so-called “mismatch problem” that is based on the observation that that there is often a mismatch between the descriptions proficient speakers associate with a word and the properties that its referents have in common. I argue that externalist theories of reference provide a plausible and attractive (...) account of concept acquisition, including the acquisition of concepts of social constructs, that avoids the mismatch problem. However, externalist theories are ontologically and psychologically highly demanding, which places strong constraints on accounts of the metaphysics of socially constructed kinds. In particular, they require a rather strong form of realism that is incompatible with some but not all theories of social constructionism. Finally, I show that these demands can be met by means of adopting a homeostatic property cluster view of natural kinds. (shrink)

The aim of this commentary is to underpin Duffley’s notion of a stable mental content that corresponds to the literal word meaning with a computationally plausible cognitive theory. Our approach is to investigate what these stable contents could be according to the so-called Predictive Processing architecture. We argue that recent advances in cognitive science can make at least two contributions to the debate. First, they can provide some underpinning of Duffley's ideas of a stable linguistic meaning associated with the sign. (...) Second, they provide resources to understand how the semiological principle is compatible with a dynamic and flexible notion of "meaning". (shrink)

Concept eliminativists argue that we should eliminate the term ‘concept’ from our vocabulary in psychology because there is no single natural kind that is picked out by it. I argue that the most developed version of concept eliminativism by Edouard Machery depends on the assumption that concepts are defined as stable and context-independent bodies of information. It is this assumption that leads Machery to eliminativism and it is an assumption we have reason to reject. Another assumption that leads to the (...) eliminativist conclusion and that we have reason to reject is that the type of content represented in long-term memory is the relevant property based on which we should individuate certain natural kinds in cognitive psychology. Finally, I argue that certain pieces of information are functionally integrated enough to meet the conditions for being a natural kind. (shrink)

Are clinical practice guidelines a means for improving the quality of health care? For saving money in the health care system? For solving the malpractice problem? For making the health care system work better for all? Or, are they a recipe for disaster? This overview sets out conceptual, definitional, and practical aspects of clinical practice guidelines as a broad framework for reflecting on the issue of what guidelines are and why they count. It draws mainly on work done since 1990 (...) at the Institute of Medicine and focuses on five questions. First, what are guidelines, and who develops them? Second, what criteria or principles should be used to create good guidelines? Third, what problems or pitfalls exist in developing and disseminating guidelines? Fourth, in what ways can guidelines help improve medical care, and in what ways will they not be as practical or useful, particularly with respect to quality of care? Finally, what ethical context might guide deliberations on this topic? (shrink)

The 9th Annual Conference of the European Business Ethics Network (EBEN) will be hosted by a national EBEN network, Deutsches Netzwerk Wirtschaftsethik (DNWE), in cooperation with a business partner, Deutsche Lufthansa AG. Far beyond the generous support which Lufthansa is providing to organize the event, the company itself stands as a symbol for the conference theme, Working Across Cultures in the Europe of Tomorrow. Working across cultures is part of their everyday business, since Lufthansa operates with 58,000 employees in over (...) 100 subsidiaries all over the world. The authors are members of the EBEN 1996 Programme Committee and represent the host institutions of the conference. Albert Löhr is member of the EBEN Executive Committee, Horst Steinmann is Chairman of the German network of EBEN, Deutsches Netzwerk Wirtschaftsethik. (shrink)

A philosopher argues that state-sponsored cyberattacks against central military or civilian targets are always acts of war. What is this philosopher doing? According to conceptual analysts, the philosopher is making a claim about our concept of war. According to philosophical realists, the philosopher is making a claim about war per se. In a quickly developing literature, a third option is being explored: the philosopher is engineering the concept of war. On this view, the philosopher is making a proposal about which (...) concept we should have – even if it deviates from the extant concept, and even if it does not capture ‘what war really is’. The activity or method of proposing such revisionary definitions, as well as the metaphilosophical reflection on it, has become known as conceptual engineering. (shrink)

The claim I want to explore in this paper is simple. In social ontology, Margaret Gilbert, Abe Roth, Michael Bratman, Antonie Meijers, Facundo Alonso and others talk about rights or entitlements against other participants in joint action. I employ several intuition pumps to argue that we have reason to assume that such entitlements or rights can be ascribed even to non-sentient robots that we collaborate with. Importantly, such entitlements are primarily identified in terms of our normative discourse. Justified criticism, for (...) example, presupposes that another person acted wrongly, i.e., was not entitled to this action. Praise is supposed to encourage another person and acknowledge that one did more than one was obligated to. I show that such normative talk serves the same function when cooperating with robots. This, I argue, suggests that they have the same kind of entitlements and duties at least in the context of a joint action. (shrink)

I identify two kinds of failure in joint action. First, we can fail to ‘do our part’, that is, fail to contribute to fulfilling the joint intention. Second, we can fail to respect our collaborators. Recognizing the distinct natures of both normative relations helps us overcome a key challenge to a reductionist theory of collective intentionality posed by Margaret Gilbert. According to this objection, we have obligations towards others even in immoral joint actions – a claim that was recently supported (...) experimentally. Except for a handful of experimental papers, work on the normativity in joint intention has stagnated. I hope the distinction breathes fresh air into the theoretical and empirical debate. (shrink)

Many psychologists currently assume that there is a psychologically real distinction to be made between concepts that are abstract and concepts that are concrete. It is for example largely agreed that concepts and words are more easily processed if they are concrete. Moreover, it is assumed that this is because these words and concepts are concrete. It is thought that interesting generalizations can be made about certain concepts because they are concrete. I argue that we have surprisingly little reason to (...) believe that the abstract‐concrete distinction is psychologically real. (shrink)

It is often stated that joint actions are linked to so-called _directed duties_. It is not just that we should “do our part” in a joint action simply because it is the right thing to do or because it is in our best interest. Instead, we “owe” it to the other participants. Despite its _prima facie_ plausibility, this claim is not well understood. Is it true that duties in joint action are directed? Which notion of directedness is relevant to understanding (...) the normativity of joint action? I first argue that we can characterize the notion of directed duties in joint action in terms of a network of inferentially related normative relations and practices. I apply this analysis to show that duties in joint action _are_ directed. This analysis supports the view that the normativity in joint action is special as it involves what Stephen Darwall calls “individual authority” without entailing “representative authority”. A perhaps surprising conclusion derived from this account is that actions in joint action are owed to everyone involved in the group equally. This supports Margaret Gilbert’s joint commitment account of joint intention. (shrink)

Der Zeichnung kommt im Trecento nicht allein in der Praxis, sondern auch als theoretisches Fundament einer „wissenschaftlich“ akzeptierbaren ars eine zentrale Rolle zu. Sie ist Medium der Bewahrung und Erneuerung, zudem auch unverzichtbares Kommunikationsmittel in den verschiedenen öffentlichen Bau- und Ausstattungsprogrammen zwischen Mailand, Florenz und Siena. An Cennino Cenninis umfassendem Praxishandbuch, dem ‚Libro dell′arte‘, sowie an einigen Beispielen der Zeichenkunst um 1400, lässt sich ablesen, dass disegno nicht allein die lernende Nachahmung und den Naturabzug, sondern auch den Auszug aus den (...) gespeicherten Sinneseindrücken meinen kann. Vor allem aber wird durch Cenninis Rede vom „Zeichen in deinem Kopf“ der graphische Akt zur Metapher der Neugestaltung der memorierten Bilddaten durch die vis imaginativa der Fantasie. Die Spuren dieser dem Werkstattgespräch entnommenen bildkünstlerischen Fachterminologie reichen allerdings weit zurück und lassen sich über Francesco Petrarca, die Dante-Kommentatoren und Dante selbst bis in die Zeit um 1300 verfolgen. Bereits in der ‚Vita Nuova‘ kann Dante mit dem terminus technicus „disegnare“ in komplexer allegorischer Rede die Fantasie als kreative Arbeit mit dem Gedächtnis hervorheben und mit einer solchen intermedialen Brechung wirkungsvoll vom verdeutlichenden Hervorbringen eines deutenden inneren Bildes durch die ekphrastisch gesteigerte literarische Repräsentation sprechen.

The article deals with the relationship between science and religion (esp. Christian faith) in two articles of physicists Max Planck and Pascual Jordan. The relationship of the two factors is reflected in the treatment of time, a subject that comes up because both articles were written on the occasion of the year's end or even the end of a decade. By analysing the two perspectives on time it is possible to distil the distinctive ideas of Planck and Jordan on religion (...) and how a religious should be related to a scientific world view. From this two different models of a positive relationship of science and religion can be formulated which transcend the framework of present discussions on the subject. In conclusion a possible role of science of religions in the dialogue between science and religion is described. (shrink)
