In "On Social Facts" (1989) and subsequent works, Margaret Gilbert has suggested a plural subject account of the semantics of ‘we’ that claims that a central or standard use of ‘we’ is to refer to an existing or anticipated plural subject. This contrasts with the more general approach to treat plural pronouns as expressions referring to certain pluralities. I argue that (i) the plural subject approach cannot account for certain syntactic phenomena and that (ii) the sense of intimacy, which Gilbert (...) cites as evidence for her plural subject account, has a different source than the existence of joint commitments constituting a respective plural subject. Moreover, (iii) there is a wide varie-ty of phenomena in the linguistic record, which, while not constituting conclusive evidence against the plural subject account, nevertheless, are dealt with better by the plurality account. ‘We’ thus refers to pluralities, which may or may not be plural subjects. The precise analysis of ‘we’ thus reveals a multi-layered ontology of groups. (shrink)

Being an "untimely review", this paper reviews Aristotle's 'Categories' as if they were published today, in the era of computerised information, where categorisation becomes more and more essential for information retrieval. I suggest a systematic ordering of Aristotle's list of categories and argue that Aristotle's discussion of ontological dependency and his focus on concrete entities are still a source of new insight and can indeed be read as a contribution to the emerging field of applied ontology and ontological engineering.

Free will is difficult to classify with respect to determinism or indeterminism, and its phenomenology in consciousness often shows both aspects. Initially, it is felt as unlimited and indeterminate will power, with the potentiality of multiple choices. Thereafter, reductive deliberation is led by determinism to the final decision, which realises only one of the potential choices. The reductive deliberation phase tries to find out the best alternative and simultaneously satisfying vague motivations, contextual conditions and personal preferences. The essential sense of (...) free will is the introduction of personal preferences, which allows a higher diversity of reactions to vague motivations. With an oversimplified model of determinism as a chain of events, incompatibilists define “free” as “undetermined” so that determinism becomes incompatible with any free choice between alternatives. In consciousness, free will requires a more complex model of network determinism as well as the consideration of unconsciousness as a causal factor. When “free” defined as “undetermined” is applied to the context of consciousness, it should be reinterpreted as “unconscious of being determined” or not aware of underlying determinism. Lacking information on determinism generates a feeling of “free” in consciousness and, therefore, gives the impression of indeterminism. Lacking information may be induced by an uncertain future without determined events—an unconscious past with biological reactions suddenly emerging from the unconsciousness or an unknown present unable to distinguish determinism of complex events. Therefore, at the level of human consciousness, the experience of free will is associated with apparent indeterminism although it is based on unconscious determinism. The concepts of compatibilism and incompatibilism are only two different aspects of the same phenomenon and correspond to consciousness and unconsciousness. Nevertheless, they can be considered together with a free will concept based on relativity depending on two different reference frames—the first person’s experience frame or the Laplace’s demon frame with knowledge on every molecule of the universe. Only relativity of the free will concept avoids the contradiction between “free” and “unfree” for the same phenomenon and could be a compromise for considering compatibilism and incompatibilism equally.

Experimental philosophers have gathered impressive evidence for the surprising conclusion that philosophers' intuitions are out of step with those of the folk. As a result, many argue that philosophers' intuitions are unreliable. Focusing on the Knobe Effect, a leading finding of experimental philosophy, we defend traditional philosophy against this conclusion. Our key premise relies on experiments we conducted which indicate that judgments of the folk elicited under higher quality cognitive or epistemic conditions are more likely to resemble those of the (...) philosopher. We end by showing how our experimental findings can help us better understand the Knobe Effect. (shrink)

: Background: In responsible research and innovation (RRI), innovation is seen as a way in which humankind finds solutions for societal issues. However, studies on commercial innovation show that firms respond in a different manner and at a different speed to the same societal issue. This study investigates what role organizational motives play in the product innovation processes of firms when aiming for socially responsible outcomes. Methods: This multiple-case study investigates the motives of food firms for healthier product innovation by (...) interviewing firms about the organizational motives behind product reformulation and innovation. Results: This study highlights the importance of having both instrumental and moral motives in the innovation process when aiming for socially responsible outcomes, and how both these motives interact and contribute to responsible innovation in industry. Furthermore, the study results question the nature of relational motives as a separate category from the other two categories of motives, as suggested by corporate social responsibility (CSR) scholars. Conclusions: If commercial innovation needs to contribute to solutions for societal issues, the importance of moral motives has to be stressed without annihilating the instrumental objectives of firms. Both motives contribute to the success factors of responsible product innovation in industry. (shrink)

In order to develop the ontology of tendencies for use in the representation of medical knowledge, tendencies are compared with other kinds of entities possessing the realizable-realization-structure, specifically: dispositions, propensities, abilities and virtues. The peculiarities of tendencies are discussed and a standard schema of tendency ascription is developed in order to represent the relations between the ascriptions of tendency tokens to particulars and the ascriptions of tendency types to universals. Two non-standard cases and their epistemic variants are discussed.

This is, to the best of my knowledge, the first published attempt at a rigorous logical formalization of a passage in Leibniz's Monadology. The method we followed was suggested by Johannes Czermak.

Like the doctrine of the categories in general, Aristotle’s category of the relative fulfils disparate functions: On the one hand, the category of the pros ti fulfils a dialectic or logical function that aims at the avoidance of fallacies. On the other hand, the category respects the peculiar mode of being of the relative. Taking these two different functions into consideration helps with the interpretation of Aristotle’s two definitions of the relative and his treatment of the properties of the relative (...) in Cat. 7, with the question whether corresponding relatives are of equal priority or ontologically independent, with the genus-species problem , and with the categorical classification of potency and act.

Recent empirical work on the concept of intentionality suggests that people’s assessments of whether an action is intentional are subject to uncertainty. Some researchers have gone so far as to claim that different people employ different concepts of intentional action. These possibilities have motivated a good deal of work in the relatively new field of experimental philosophy. The findings from this empirical research may prove to be relevant to medical ethics. In this article, we address this issue head on. We (...) first describe a study we conducted on intention ascription. Drawing on recent work in experimental philosophy, we investigated the possibility that the ascription of intentions to clinical actors in clinical settings is influenced by prior judgments about the goodness or badness of the consequences of the action in question. Our study was modeled on experimental studies in other contexts that have shown that people, when presented with a range of scenarios, are more likely to classify a side effect of an action as intended if the side effect is negative or reflects poorly on the actor than if it is positive or reflects well on the actor. We investigated whether this asymmetry in intention ascriptions was also present among physicians who were asked to ascribe intentions to clinical actors in certain well-defined clinical scenarios. After describing the study and its results, we discuss its implications for medical ethics. (shrink)

Taking Thomas Aquinas's interpretation of the prologue of St John's gospel (in his Lectura super loannem Evangelium) as example, I first discuss eight differences between medieval biblical interpretation and modern exegesis, especially Aquinas's frequent use of philosophical opinions in interpreting the Bible, taken mostly from Aristotle. Second, I account for these differences by reconstructing Aquinas's hermeneutics, hinging, as is shown, upon the assumption that scripture was authored by God infallible and, therefore, only contains true statements. From this starting point Aquinas (...) is lead to a holistic hermeneutics: The interpretation of a biblical statement can be judged on only within the context of an entire theory of God, the world, and of the interpretation of the other biblical statements. Thirdly, this view is discussed systematically and critically. (shrink)

Wether the chicken or the egg came first, is not only a mind-boggling but a substantial question. Its answer depends on the biological background theory one assumes. I review recent work on the topic (by Teichmann, Sorensen, Waller and Raatzsch) and resolve some of the disputes between these authors by borrowing from Aristotle the distinction between chicken-producing eggs. I then introduce the concept of a quasi-species to make explicit the vagueness involved in species-terms and prove 13 different priority-claims within a (...) Darwinian framework. (shrink)

Having an agreed-upon definition of character education would be useful for both researchers and practitioners in the field. However, even experts in character education disagree on how they would define it. We attempted to achieve greater conceptual clarity on this issue through a prototype analysis in which the features perceived as most central to character education were identified. In Study 1 (N = 77), we asked character education experts to enumerate features of character education. Based on these lists, we identified (...) 30 features. In Study 2 (N = 101), experts assessed which features were central to character education through a categorization task. In Study 3 (N = 166), we assessed the extent of centrality using scalar items. We conclude by offering practical advice for the development of future character education studies and programs rooted in what is deemed central to such programs. (shrink)

On 4th of August 2020, the Lebanese capital and port city, Beirut, was rocked by a massive explosion that has killed hundreds and injured thousands more, ravaging the heart of the city’s nearby downtown business district and neighbouring housing areas, where more than 750,000 people live. The waterfront neighbourhood and a number of dense residential neighbourhoods in the city’s eastern part were essentially flattened. Lebanese Government officials believe that the blast was caused by around 2,700 tonnes of ammonium nitrate stored (...) near the city’s cargo port without proper control for six years. -/- The disaster devastating Beirut’s port and city shows the latent danger of safe storage of potentially dangerous goods in modern ports, particularly ones located close to the heart of the city. The huge blast tore through major grain silos, stoking fears of shortages in a nation that imports nearly all its food and is already reeling from economic crisis. As the WFP (World Food Programme) said in a statement: the blast will “exacerbate the grim economic and food-security situation.” The Beirut blast also reminds us of the importance of ports in the contemporary globalized world. It calls our attention to safety and security, of governance and collaboration between port and city or region and of accessibility to the hinterland. What do local governments and port cities need to do to enhance the safety and security issues in port terminals? Or, to put it differently, how do we reconcile this challenge between the ports we need to feed us, serve us, provide us with medicines, equipment, etc. and the ports that threatens us? (shrink)

In this paper we raise the question whether technological artifacts can properly speaking be trusted or said to be trustworthy. First, we set out some prevalent accounts of trust and trustworthiness and explain how they compare with the engineer’s notion of reliability. We distinguish between pure rational-choice accounts of trust, which do not differ in principle from mere judgments of reliability, and what we call “motivation-attributing” accounts of trust, which attribute specific motivations to trustworthy entities. Then we consider some examples (...) of technological entities that are, at first glance, best suited to serve as the objects of trust: intelligent systems that interact with users, and complex socio-technical systems. We conclude that the motivation-attributing concept of trustworthiness cannot be straightforwardly applied to these entities. Any applicable notion of trustworthy technology would have to depart significantly from the full-blown notion of trustworthiness associated with interpersonal trust. (shrink)

There are group-actions, and if actions are intentional, there should also be group-intentions. Who has got these intentions? The groups? This seems to be the natural answer. But then: Groups do not have a mind or brain of there own to form any mental attitude. Different kinds of individualistic analyses of group-intentions have been suggested in the literature. On the one hand there are suggestions to reduce group intentions to a complex of different Iattitudes. John Searle, on the other hand, (...) suggests a special social kind of attitudes, namely we-intentions. We-intentions are being had by individual persons, though they have the form “We intend to do such-and-such”. However, because of the fallibility of Searlian we-intentions and the possibility of ignorance this concept is of no help: We-intentions are neither necessary nor sufficient for group-intentions. In this respect, Margaret Gilbert’s approach is much more successful, though it covers only a special case, namely small-scale informal groups. I suggest a generalised solution in order to cover also large-scale and formal groups. (shrink)

Vigorous debate over the moral propriety of cognitive enhancement exists, but the views of the public have been largely absent from the discussion. To address this gap in our knowledge, four experiments were carried out with contrastive vignettes in order to obtain quantitative data on public attitudes towards cognitive enhancement. The data collected suggest that the public is sensitive to and capable of understanding the four cardinal concerns identified by neuroethicists, and tend to cautiously accept cognitive enhancement even as they (...) recognize its potential perils. The public is biopolitically moderate, endorses both meritocratic principles and the intrinsic value of hard work, and appears to be sensitive to the salient moral issues raised in the debate. Taken together, these data suggest that public attitudes toward enhancement are sufficiently sophisticated to merit inclusion in policy deliberations, especially if we seek to align public sentiment and policy.

Aristoteles unterscheidet zwischen zwei Arten, das Wort „dynaton" zu gebrauchen. Die erste dieser beiden Verwendungsweisen dient zur Zuschreibung von Vermögen (dynaton kata dynamin), die zweite entspricht unserer Verwendung des logisch-alethischen Modaloperators „Es ist möglich, dass" (dynaton ou kata dynamin). Ich argumentiere dafür, dass wichtige Unterschiede zwischen Vermögensprädikationen und Modalaussagen bestehen. Ich nenne mehrere Gründe dafür, dass Vermögensprädikationen keine Modalaussagen sind, zeige aber auch, dass Vermögensprädikationen zwei modale Elemente haben: Sie implizieren erstens nichttriviale Modalaussagen, weil es keine Vermögen für Unmögliches gibt. (...) Und sie implizieren zweitens nichttriviale Aussagen über kontrafaktische Situationen, weil sie Aussagen über kausale Rollen sind. (shrink)

We shall focus on moral theories that are solely concerned with promoting the benefits (e.g., wellbeing) of individuals and explore the possibility of such theories ascribing some priority to benefits to those who are worse off—without this priority being absolute. Utilitarianism (which evaluates alternatives on the basis of total or average benefits) ascribes no priority to the worse off, and leximin (which evaluates alternatives by giving lexical priority to the worst off, and then the second worst off, and so on) (...) ascribes absolute priority to the worse off (i.e., favors even a very small benefit to a worse off person over very large benefits to large numbers of better off people). Neither extreme view, we assume, is plausible. (shrink)

Given the assertion of a relation between two types, like: “Epidermis has part some Keratinocyte”, we define silent change as any kind of change of the instance-relata of the relation in question that does not change the truth-value of the respective type-level assertion. Such assertions are notoriously difficult to model in OWL 2. To address this problem, we distinguish different modes of type-level relatedness giving rise to this problem and describe a conservative extension to the BFO top-level ontology that allows (...) expressing these modes.

Concerns about the risks of unmitigated greenhouse gas emissions are growing. At the same time, confidence that international policy agreements will succeed in considerably lowering anthropogenic greenhouse gas emissions is declining. Perhaps as a result, various geoengineering solutions are gaining attention and credibility as a way to manage climate change. Serious consideration is currently being given to proposals to cool the planet through solar-radiation management. Here we analyze how the unique and nontrivial risks of geoengineering strategies pose fundamental questions at (...) the interface between science and ethics. To illustrate the importance of integrated ethical and scientific analysis, we define key open questions and outline a coupled scientific-ethical research agenda to analyze solar-radiation management geoengineering proposals. We identify nine key fields of coupled research including whether solar-radiation management can be tested, how quickly learning could occur, normative decisions embedded in how different climate trajectories are valued, and justice issues regarding distribution of the harms and benefits of geoengineering. To ensure that ethical analyses are coupled with scientific analyses of this form of geoengineering, we advocate that funding agencies recognize the essential nature of this coupled research by establishing an Ethical, Legal, and Social Implications program for solar-radiation management.

The constituents of social entities (and of social continuants in particular) determine whether or not a social thing comes to be, persists and perishes. John Searle hints at two very different accounts for the persistence of social entities, a mere past related account and an acceptance theoretic account, whereas Margaret Gilbert's account is based on deontic entities like obligations or joint commitments. I demonstrate that Gilbert's account can also accommodate Searle's examples. While oblivion, protests or violence can be historical causes (...) of the destruction of social entities, they cannot be considered to be the ultimate causes of the perishing from Gilbert's point of view. Social entities rather perish because of the treatises or divorces that dissolve their deontic constituents. (shrink)

Recent research has begun to investigate sensory processing in relation to nonclinical variation in traits associated with the autism spectrum disorders (ASD). We propose that existing accounts of autistic perception can be augmented by considering a role for individual differences in top-down expectations for the precision of sensory input, related to the processing of state-dependent levels of uncertainty. We therefore examined ASD-like traits in relation to the rubber-hand illusion: an experimental paradigm that typically elicits crossmodal integration of visual, tactile, and (...) proprioceptive information in an unusual illusory context. Individuals with higher ASD-like traits showed reduced effects of the rubber-hand illusion on perceived arm position and reach-to-grasp movements, compared to individuals with lower ASD-like traits. These differences occurred despite both groups reporting the typical subjective experience of the illusion concerning visuotactile integration and ownership for the rubber hand. Together these results suggest that the integration of proprioceptive information with cues for arm position derived from the illusory context differs between individuals partly in relation to traits associated with ASD. We suggest that the observed differences in sensory integration can be best explained in terms of differing expectations regarding the precision of sensory estimates in contexts that suggest uncertainty.

Not only the direct physical experiences of deployment can severely harm soldiers’ mental health. Witnessing violations of their moral principles by the enemy, or by their fellow soldiers and superiors, can also have a devastating impact. It can cause soldiers’ moral disorientation, increasing feelings of shame, guilt, or hate, and the need for general answers on questions of right and wrong. Various attempts have been made to keep soldiers mentally sane. One is to provide convincing causes for their deployment, which (...) risks an “end justifies the means” way of thinking. The good cause can provide a moral justification for horrible atrocities. Another method, introduced in the USA, Canada, and Australia, aims to strengthen military personnel’s resistance by promoting and maintaining a happy, optimistic state of mind through the use of positive psychology. Alongside making soldiers “morally fit” for all kinds of situations, the focus could also be on moral recovery and forgiveness. Such a care-based military ethics approach, aimed at mutual understanding and interdependence, could help soldiers handle the emotional impact of moral conflicts. This demands that military units reflect on their organizational culture and rethink oaths and codes of conduct that focus mainly on efficiency and readiness, as well as the soldierly self-image with its seemingly still deeply rooted warrior ethos. Today, resilience and positive psychology in the military is apparently mainly geared to assuring its soldiers’ readiness. An appropriate set of virtues and understanding of virtue ethics that are less centered on self-perfection and autonomy could point to a different form of character-building and lead to a better understanding of others.

Autism spectrum disorder is characterised by differences in unimodal and multimodal sensory and proprioceptive processing, with complex biases towards local over global processing. Many of these elements are implicated in versions of the rubber hand illusion, which were therefore studied in high-functioning individuals with ASD and a typically developing control group. Both groups experienced the illusion. A number of differences were found, related to proprioception and sensorimotor processes. The ASD group showed reduced sensitivity to visuotactile-proprioceptive discrepancy but more accurate proprioception. (...) This group also differed on acceleration in subsequent reach trials. Results are discussed in terms of weak top-down integration and precision-accuracy trade-offs. The RHI appears to be a useful tool for investigating multisensory processing in ASD. (shrink)

Is a bank note identical with the piece of paper of which it consists? On the one hand, John Searle, in his reply to Barry Smith, suggests that they are “one and the same object” that is a social or non-social object only under certain descriptions. On the other hand, Lynne Rudder Baker puts forward the claim that bank note and paper are distinct entities that are bound together by the relation of material constitution. I suggest two possible analyses for (...) Searle’s description relativity claim, the Alternative Subject Analysis and the Predicate Modification Analysis. On both accounts his identity claim gets into serious trouble. While Baker’s definition of material constitution deals well with the bank note example, it fails to account for the constitution of bearerless social entities and groups. I point out five respects in which social constitution can differ from Baker’s account of material constitution and discuss compositional, institutional and interactional constitution as additional varieties of social constitution.

Peter Ludlow shows how word meanings are much more dynamic than we might have supposed, and explores how they are modulated even during everyday conversation.

Die Zeiten, in denen der Leib-Seele-Dualismus als Ansatz der Philosophie des Geistes durch ein herrschendes Dogma als diskussionsunwürdig galt, sind vorbei. Der Dualismus darf wieder diskutiert werden. Er muß diskutiert werden, wenn in diskussionswürdiger Strenge für ihn argumentiert wird – auch wenn das, wie sich zeigen wird, manchmal ein ziemlich technisches Geschäft ist. In diesem Sinne soll im folgenden Richard Swinburnes Versuch behandelt werden, die Existenz einer Seele und damit die Wahrheit des Substanzdualismus aus einigen zunächst recht unspektakulär aussehenden Prämissen (...) mit Hilfe der modernen Modallogik formal zu beweisen. Zugleich sei damit auf eine kleine Debatte aufmerksam gemacht, die sich inzwischen um Swinburnes Argument entwickelt hat. Die Untersuchung führt zu einem doppelten negativen Ergebnis: Zum einen sind Swinburnes Prämissen nicht plausibel, zum anderen ist ein wichtiger Teil seines Beweisversuches formal nicht in Ordnung. Swinburnes Argument ist also weder überzeugend noch gültig . Allerdings ist das nicht auf den ersten Blick ersichtlich, denn Swinburnes Argument ist alles andere als trivial. Eine eingehende Kritik dieses Arguments soll zeigen, daß, selbst wenn der Dualismus wahr sein sollte, er nicht ganz so einleuchtend ist, wie Swinburne meint. (shrink)

The goal of the 2010 Ontology Summit was to address the current shortage of persons with ontology expertise by developing a strategy for the education of ontologists. To achieve this goal we studied how ontologists are currently trained, the requirements identified by organizations that hire ontologists, and developments that might impact the training of ontologists in the future. We developed recommendations for the body of knowledge that should be taught and the skills that should be developed by future ontologists; these (...) recommendations are intended as guidelines for institutions and organizations that may consider establishing a program for training ontologists. Further, we recommend a number of specific actions for the community to pursue. (shrink)

The Protein Ontology (PRO; http://proconsortium.org) formally defines protein entities and explicitly represents their major forms and interrelations. Protein entities represented in PRO corresponding to single amino acid chains are categorized by level of specificity into family, gene, sequence and modification metaclasses, and there is a separate metaclass for protein complexes. All metaclasses also have organism-specific derivatives. PRO complements established sequence databases such as UniProtKB, and interoperates with other biomedical and biological ontologies such as the Gene Ontology (GO). PRO relates to (...) UniProtKB in that PRO’s organism-specific classes of proteins encoded by a specific gene correspond to entities documented in UniProtKB entries. PRO relates to the GO in that PRO’s representations of organism-specific protein complexes are subclasses of the organism-agnostic protein complex terms in the GO Cellular Component Ontology. The past few years have seen growth and changes to the PRO, as well as new points of access to the data and new applications of PRO in immunology and proteomics. Here we describe some of these developments. (shrink)

We investigate risk attitudes when the underlying domain of payoffs is finite and the payoffs are, in general, not numerical. In such cases, the traditional notions of absolute risk attitudes, that are designed for convex domains of numerical payoffs, are not applicable. We introduce comparative notions of weak and strong risk attitudes that remain applicable. We examine how they are characterized within the rank-dependent utility model, thus including expected utility as a special case. In particular, we characterize strong comparative risk (...) aversion under rank-dependent utility. This is our main result. From this and other findings, we draw two novel conclusions. First, under expected utility, weak and strong comparative risk aversion are characterized by the same condition over finite domains. By contrast, such is not the case under non-expected utility. Second, under expected utility, weak comparative risk aversion is characterized by the same condition when the utility functions have finite range and when they have convex range. By contrast, such is not the case under non-expected utility. Thus, considering comparative risk aversion over finite domains leads to a better understanding of the divide between expected and non-expected utility, more generally, the structural properties of the main models of decision-making under risk.

Measures and theories of information abound, but there are few formalised methods for treating the contextuality that can manifest in different information systems. Quantum theory provides one possible formalism for treating information in context. This paper introduces a quantum inspired model of the human mental lexicon. This model is currently being experimentally investigated and we present a preliminary set of pilot data suggesting that concept combinations can indeed behave non-separably.

We present a formal semantics for epistemic logic, capturing the notion of knowability relative to information (KRI). Like Dretske, we move from the platitude that what an agent can know depends on her (empirical) information. We treat operators of the form K_AB (‘B is knowable on the basis of information A’) as variably strict quantifiers over worlds with a topic- or aboutness- preservation constraint. Variable strictness models the non-monotonicity of knowledge acquisition while allowing knowledge to be intrinsically stable. Aboutness-preservation models (...) the topic-sensitivity of information, allowing us to invalidate controversial forms of epistemic closure while validating less controversial ones. Thus, unlike the standard modal framework for epistemic logic, KRI accommodates plausible approaches to the Kripke-Harman dogmatism paradox, which bear on non-monotonicity, or on topic-sensitivity. KRI also strikes a better balance between agent idealization and a non-trivial logic of knowledge ascriptions. (shrink)

There has been some recent optimism that addressing the question of how we distinguish sensory modalities will help us consider whether there are limits on a scientific understanding of perceptual states. For example, Block has suggested that the way we distinguish sensory modalities indicates that perceptual states have qualia which at least resist scientific characterization. At another extreme, Keeley argues that our common-sense way of distinguishing the senses in terms of qualitative properties is misguided, and offers a scientific eliminativism about (...) common-sense modalities which avoids appeal to qualitative properties altogether. I’ll argue contrary to Keeley that qualitative properties are necessary for distinguishing senses, and contrary to Block that our common-sense distinction doesn’t indicate that perceptual states have qualia. A non-qualitative characterization of perceptual states isn’t needed to avoid the potential limit on scientific understanding imposed by qualia. (shrink)

This paper is about teaching philosophy to high school students through Lincoln-Douglas (LD) debate. LD, also known as “values debate,” includes topics from ethics and political philosophy. Thousands of high school students across the U.S. debate these topics in class, after school, and at weekend tournaments. We argue that LD is a particularly effective tool for teaching philosophy, but also that LD today falls short of its potential. We argue that the problems with LD are not inevitable, and we offer (...) strategic recommendations for improving LD as a tool for teaching philosophy. Ultimately, our aim is to create a dialogue between LD and academic philosophy, with the hope that such dialogue will improve LD’s capacity to teach students how to do philosophy. (shrink)
