How do opinion diversity and belief polarisation affect epistemic group decision-making, particularly if decisions must be made without delay and on the basis of permissive evidence? In an agent-based model, we track the consistency of group opinions aggregated through sentence-wise majority voting. Simulations on the model reveal that high opinion diversity, but not polarisation, incurs a significant inconsistency risk. These results indicate that epistemic group decisions based on permissive evidence can be particularly difficult for diverse groups. The results also improve (...) our understanding of what can reasonably be expected of expert groups, and where expert advice might have limits. (shrink)

Computational models have shown how polarisation can rise among deliberating agents as they approximate epistemic rationality. This paper provides further support for the thesis that polarisation can rise under condition of epistemic rationality, but it does not depend on limitations that extant models rely on, such as memory restrictions or biased evaluation of other agents’ testimony. Instead, deliberation is modelled through agents’ purposeful introduction of arguments and their rational reactions to introductions of others. This process induces polarisation dynamics on its (...) own. A second result is that the effect size of polarisation dynamics correlates with particular types of argumentative behaviour. Polarisation effects can be soothed when agents take into account the opinions of others as premises, and they are amplified as agents fortify their own beliefs. These results underpin the relevance of argumentation as a factor in social-epistemic processes and indicate that rising issue polarisation is not a reliable indicator of epistemic shortcomings.

One of the moral questions concerning autonomous vehicles (henceforth AVs) is the choice between types that differ in their built-in algorithms for dealing with rare situations of unavoidable lethal collision. It does not appear to be possible to avoid questions about how these algorithms should be designed. We present the results of our study of moral preferences (N = 2769) with respect to three types of AVs: (1) selfish, which protects the lives of passenger(s) over any number of bystanders; (2) (...) altruistic, which minimizes the number of casualties, even if this leads to death of passenger(s); and (3) conservative, which abstains from interfering in such situations. We differentiate between scenarios in which participants are to make their decisions privately or publicly, and for themselves or for their offspring. We aim to answer two research questions: (1) whether the public visibility of the choice of an AV type choice make this choice more altruistic and (2) which type of situation makes it more difficult to choose altruistically: when choosing for society as a whole, when choosing only for oneself, or when choosing only for one’s offspring. Our results show that respondents exhibit a preference for an altruistic strategy for AVs and that it is reinforced when signaled to others. The altruistic preference is strongest when applies to everybody else, weaker when it reflects a solely personal choice, and weakest when choosing for one’s own child. We conclude that a public choice is considerably more likely to pressure consumers into accepting a more socially beneficial solution. (shrink)

The pragmatist account of action in Brandom’s Making it Explicit offers a compelling defense of social embeddedness of acting. Its virtue consists of redefining the agent’s reasons for action in terms of her public commitments and entitlements. However, this account remains too intellectualist insofar as it neglects the embodied sense allowing the agent to respond to various situational demands and social constraints. In my article, I provide a less disembodied account of action that draws on Dreyfus’s emphasis on bodily skills (...) as constitutive aspects of intentional acting. Dreyfus’ notion of absorbed coping certainly highlights the role of body and affectivity in guiding the performance of action, but it ends up in underestimating the role of discursive and conceptual capacities in human agency. Against Dreyfus, I will demonstrate that involved and embodied coping not only answers to the demands of a given situation, but also involves responsiveness to reasons. My ambition is to defend a continuity between practical reasoning, i.e. our capacity to justify our performances through reasons, and our embodied coping skills, a continuity that has been overlooked by Brandom’s intellectualist and denied by Dreyfus’ anti-rationalist accounts.

Tato studie se zabývá dvěma spřízněnými jevy odehrávajícími se ve vědeckém prostředí. Jedná se o fenomén frustrace ve vědecké praxi a s ním spojenou touhu po rozpoznání vlastního výzkumu vědeckou komunitou a následně o otázku uznání od akademického společenství. Zmíněné fenomény jsou přitom úzce propojeny s ústředním tématem filosofie a sociologie vědy: kdo rozhoduje, co bude předmětem vědeckého bádání? Předkládaná studie nejprve představuje Mertonův mýtus o okamžitém rozpoznání vědeckého objevu a následně prostřednictvím exkurzu do oblasti ekonomie a na příkladech z (...) vědecké praxe poukazuje na jeho neplatnost. V závěru textu jsou společně s jejich dekonstrukcí navrhnuta možná řešení popsaných problémů. Text je také kritickým návratem ke dvěma studiím Josepha Agassiho, žáka Karla R. Poppera a tvrdošíjného zastánce kritického racionalismu, neboť právě Agassi ve svých dílech rozebírá dopady vědeckého vyloučení a neochoty naslouchat. (shrink)

Článek se zabývá problematickou politické korektnosti ve vztahu k feministické filosofii vědy. Zaměřuje pozornost na užší pojem politické korektnosti - hodnotově motivovanou nekorektní práci s fakty. Konstatuje, že navzdory explicitnímu soustředění feministických autorek a autorů na význam hodnot v projektu vědy nelze chápat feministickou filosofii vědy jako politicky korektní nebo jako vybízení k politicky korektní vědě. Naopak se politicky korektní argumentace v tomto užším smyslu mohou dopouštět i práce vystupující proti feministické či politicky korektní agendě ve vědě.

Příspěvek zprostředkovává základní vhled do bitvy o absolutní, jak bývá často označována polemika mezi Josiahem Roycem a Williamem Jamesem. Toto intelektuální zápolení, do něhož významně zasahovali Charles S. Peirce nebo John Dewey, je jedním z důležitých faktorů ovlivňujících podobu názorů amerických pragmatiků. Příspěvek se soustřeďuje především na období mezi lety 1899 a 1902, kdy je bitva o absolutní nejvyostřenější a filosoficky nejplodnější. Představené závěry jsou důležité především ve vztahu k probíhající renesanci názorů pragmaticky smýšlejících autorů v současných kognitivních vědách či (...) filosofii vědy. (shrink)

Na základě analýzy otázky, jak se učíme ze zkušenosti představuje studie problém indukce nejprve tak, jak byl formulován Humem skrze jeho příčinu v nezdůvodnitelnosti principu uniformity přírody. Následně ukazuje Popperovo řešení problému spočívající v naprostém odmítnutí induktivního usuzování. Popperův přístup je podroben srovnání s reliabilistickou pozicí Davida Papineau - stanoviskem, že poznání je pravdivým přesvědčením generovaným spolehlivou metodou. Hlavním cílem textu je znovuotevření diskuze nad tématem neplatnosti indukce a možná redukce námitek vůči její logické neplatnosti na základě nahlédnutí reliabilistického stanoviska. (...) Vedlejším záměrem je pak ilustrovat možné styčné body mezi kritickým racionalismem s jeho důrazem na delegitimizaci vědění a reliabilistickým kritériem spolehlivosti. (shrink)

Předložený článek si na základě rozboru hlavních motivů ve Foucaultově a Canguilhemově pojetí norem klade za cíl vymezit, jaká je vzájemná vazba mezi biologickou a společenskou normativitou a jakým typem moci na nás normy vlastně působí. V souladu s interpretací navrženou Pierrem Macherey se pokusíme sílu norem vystihnout v termínech jejich „imanence a produktivity" a ukázat, proč nelze normy chápat dle modelu zákona, který by ke svému předmětu přistupoval zvnějšku. Poslední část pak přináší odpověď na otázku, jaký typ individualizace či (...) subjektivizace toto pojetí diskvalifikuje a jaké možnosti ponechává pro svébytnou singularitu v rámci normativního pole.

The dissertation investigates whether virtue ethics can provide the normative ground for the justification of rights. Most justificatory accounts of rights consist in different explanations of the function of rights. On the view I will defend, rights have a plurality of functions and one of the main functions of rights is to make the right-holder more virtuous. The idea that the possession of rights leads to the development of virtues, called the function of virtue acquisition, is the core of a (...) virtue-based justification of rights elaborated in this dissertation. Based on Leif Wenar’s Kind-Desire Theory of rights and Nancy E. Snow’s Minimal Virtue of the Folk, I argue that there are two general types of rights, enabling rights and protective rights, and that both types are essential to the development of virtues. Enabling rights have the function of virtue acquisition because they allow the right-holder to strive for approximation of ideal role models while performing duties and other tasks. Such models are called heuristic models of virtues for they define what virtues are and how these virtues should be expressed in action. Some protective rights, namely promissory rights and the power-right to promise, behave like enabling rights when it comes to their ability to develop virtues. Other protective rights, especially children’s rights, make right-holders more virtuous via protecting their essential needs. The dissertation succeeds in elaborating the virtue-based justification of many rights, hence it suggests that people hold and should have rights because rights make them better people. (shrink)

When reusing existing ontologies for publishing a dataset in RDF (or developing a new ontology), preference may be given to those providing extensive subcategorization for important classes (denoted as focus classes). The subcategories may consist not only of named classes but also of compound class expressions. We define the notion of focused categorization power of a given ontology, with respect to a focus class and a concept expression language, as the (estimated) weighted count of the categories that can be built (...) from the ontology’s signature, conform to the language, and are subsumed by the focus class. For the sake of tractable initial experiments we then formulate a restricted concept expression language based on existential restrictions, and heuristically map it to syntactic patterns over ontology axioms (so-called FCE patterns). The characteristics of the chosen concept expression language and associated FCE patterns are investigated using three different empirical sources derived from ontology collections: first, the concept expression pattern frequency in class definitions; second, the occurrence of FCE patterns in the Tbox of ontologies; and last, for class expressions generated from the Tbox of ontologies (through the FCE patterns); their ‘meaningfulness’ was assessed by different groups of users, yielding a ‘quality ordering’ of the concept expression patterns. The complementary analyses are then compared and summarized. To allow for further experimentation, a web-based prototype was also implemented, which covers the whole process of ontology reuse from keyword-based ontology search through the FCP computation to the selection of ontologies and their enrichment with new concepts built from compound expressions.
