The history of the research on peptic ulcer disease is characterized by a premature abandonment of the bacterial hypothesis, which subsequently had its comeback, leading to the discovery of Helicobacter pylori – the major cause of the disease. In this paper we examine the received view on this case, according to which the primary reason for the abandonment of the bacterial hypothesis in the mid-twentieth century was a large-scale study by a prominent gastroenterologist Palmer, which suggested no bacteria could be (...) found in the human stomach. To this end, we employ the methodof digital textual analysis and study the literature on the etiology of PUD published in the decade prior to Palmer’s article. Our findings suggest that the bacterial hypothesis had already been abandoned before the publication of Palmer’s paper, which challenges the widely held view that his study played a crucial role in the development of this episode. In view of this result, we argue that the PUD case does not illustrate harmful effects of a high degree of information flow, as it has frequently been claimed in the literature on network epistemology. Moreover, we argue that alternative examples of harmful effects of a high degree of information flow may be hard to find in the history of science. (shrink)

Our findings suggest that the bacterial hypothesis of PUD had already been abandoned before the publication of Palmer's paper, which challenges the widely held view that his study played a crucial role in the development of this episode. The paper makes two main contributions to the literature in integrated history and philosophy of science. First, we suggest that the received narrative on this historical episode, commonly used by philosophers, needs to be revised. Second, we introduce the notion of a `declining research program' and argue for its importance as a unit of socio-epistemic analysis, especially in combination with normative assessments, such as pursuitworthiness of scientific theories.

Despite the great expansion and many benefits of information and communication technologies in healthcare, the attitudes of Polish general practitioners to e-health have not been explored. The aim of this study was to determine the GPs’ perception of ICT use in healthcare and to identify barriers to the adoption of EMR in the Podlaskie Voivodeship. Online and telephone surveys were conducted between April and May 2013. Responses from 103 GP practices, 43% of all practices in the region, were analysed. The (...) results showed that 67% of the respondents agreed that IT systems improve quality of healthcare services. In the GP group who declared at least partial EMR implementation, 71.4% see the positive impact of IT on practice staff processes and 66.1% on personal working processes. In this group, more than three-quarters of GPs did not see any positive impact of ICT on the average number of patients treated per day, number of patients within the practice or scope of services. The four most common barriers to EMR implementation were: lack of funds, risk of a malfunction in the system, resistance to change, and lack of training and proper information. Although the use of ICT by Polish GPs is limited, their attitude to e-health is generally positive or neutral and resembles the overall pattern in Europe. Barriers identified by GPs need to be taken into account to ensure the effective implementation of e-health across the country. (shrink)

The paper concerns the problem of the legal responsibility of autonomous machines. In our opinion it boils down to the question of whether such machines can be seen as real agents through the prism of folk-psychology. We argue that autonomous machines cannot be granted the status of legal agents. Although this is quite possible from purely technical point of view, since the law is a conventional tool of regulating social interactions and as such can accommodate various legislative constructs, including legal (...) responsibility of autonomous artificial agents, we believe that it would remain a mere ‘law in books’, never materializing as ‘law in action’. It is not impossible to imagine that the evolution of our conceptual apparatus will reach a stage, when autonomous robots become full-blooded moral and legal agents. However, today at least, we seem to be far from this point. (shrink)

This paper is an attempt to examine Mattias Kiesselbach’s account of the thesis that meaning is normative that was presented in his recently published article titled “The normativity of meaning: from constitutive norms to prescriptions.” Kiesselbach’s account has three crucial points: the applicability of norms, the transtemporal character of the constitutive norms and commitments incurred by or attributed to the speaker within the scorekeeping practice. I will discuss all these crucial points, and I will argue that his account raises many (...) questions and the anti-prescriptivist about meaning can have reasonable doubts about all of them.

The aim of this paper is to suggest how the internal logic and dynamics of the development of Cartesian philosophy can be reconstructed by means of the historical-theoretical analysis of one of the most forgotten lines of reception of Cartesianism, leading through the philosophy of British thinkers minorum gentium: Arthur Collier, John Norris, Richard Burthogge etc. Such analysis of the particular stages of the evolution of post-Cartesian thought – within one intellectual-cultural context, makes it possible to situate Berkeley’s system (considered (...) as a culminating point of the development of post-Cartesian British idealism) in the stream of the widely understood Cartesian thought. At the same time the analysis provides sufficient data to draw some general conclusions regarding the logic of the development of Cartesian-inspired philosophical systems. (shrink)

We have taken a look at the rules of games in order to acquire some knowledge concerning constitutive rules and, probably, institutional phenomena in general. In this paper we tried to elaborate a system account of constitutive rules. We claim that all accounts that put emphasis on the form of rules are vulnerable. It appears that constitutive rules are interconnected and always form a system that can be internally differentiated. Thanks to adopting certain qualitative criterion we were able to distinguish (...) central and peripheral constitutive rules. Moreover, that very account makes it possible to distinguish between different types of practices that are determined by types of systems of rules. Secondly, it appears there are three “layers” of games that should not be confused: deep conventions, constitutive rules that establish the game and determine games’ identities, and “rules of efficiency” that are some sort of recommendations as to how to play well.

In proof-theoretic semantics the meaning of an atomic sentence is usually determined by a set of derivations in an atomic system which contain that sentence as a conclusion (see, in particular, Prawitz, 1971, 1973). The paper critically discusses this standard approach and suggests an alternative account which proceeds in terms of subatomic introduction and elimination rules for atomic sentences. A simple subatomic normal form theorem by which this account of the semantics of atomic sentences and the terms from which they (...) are composed is underpinned, shows moreover that the proof-theoretic analysis of first-order logic can be pursued also beneath the atomic level.

Many aquatic invasive species management programs are doing important work on preventing non-indigenous species movement to our wild places. Attitudes and perspectives on aquatic non-indigenous species and their management by ecologists and the public are fundamentally a question of human values. Despite eloquent philosophical writings on treatment of non-indigenous species, management agency rhetoric on 'invasive' species usually degenerates to a good versus evil language, often with questionable results and lost conservation dollars. We assess and learn from an established AIS program. (...) We discuss an ethic framework and operational directives to minimise the trap of a binary classification of species into bad or good, and we advocate for a principled pragmatic approach to minimise conflicts. We make a case for not labelling species and instead focusing on managing nuisance conditions and protecting ecosystem health. (shrink)

ARE NEURAL CORRLEATES OF CONSCIOUSSNESS NECESSARY FOR PHILOSOPHY? This article discusses philosophical issues concerning theory of neural correlates of consciousness (NCC) and the possible philosophical interpretation of the positions taken by scholars dealing with these issues, whether these views expressly refer to the philosophy of mind, or not. In the first part I will present existing theories regarding the NCC, and try to find their common ground. The concept of NCC was defined by D. Chalmers, by F. Crick and Ch. (...) Koch, and by A. Damasio and it is argued that those definitions are perfectly complementary. The summary of this section presents the methodological problems associated with the theory of NCC pointed out by J. Bremer. In the second part, the intersection of the positions is contrasted with the classical discussion concerning the philosophy of mind and interpreted from a philosophical point of view. In particular, the issue of possible points of contact between the classical phenomenological method and NCC is pursued. (shrink)

The difference between so-called performative/pragmatic and logical contradiction seems to be one of the most firmly established philosophical distinctions. There are, however, some utterances, which fall outside this classification in its current form. Moreover, they reveal that the expressive power of the language of classical logic is too weak to express some form of the logical contradiction. The main aim of this paper is to characterize this special case of the contradiction. By extending classical logic with a new connective, i.e. (...) content implication, it also provides tools needed for adequate formal representation of this phenomenon. (shrink)

In this article I am going to argue that despite the fact that (1) there is nothing specific to the form of constitutive rules and (2) that in some broad sense every rule has a constitutive aspect, there is a substantial difference between what might be called trivially and genuinely constitutive rules, and the difference can be spotted by looking at practices that rules are supposed to constitute, not at these rules.

The paper focuses on a linguistic analysis of Berkeley’s doctrine of existence. It has been shown that the traditional, relational-operational interpretation of Berkeley's existential claims must be expanded by adding a predicative element, which requires that they also be interpret as definitional copulas. The standard interpretation of Berkeley’s claims has been indicated as one of the main causes of misinterpretations of his metaphysics. The new, philosophically intriguing use of the verb ‘to be’, combining features of the definitional copula and the (...) auxiliary verb for the passive voice, is also described in this paper.

[ENG] The aim of this paper is to analyze the „possibility puzzle” presented by Shapiro (2011) in the context of the debate between conventionalism and non-conventionalism in speech act theory. Conventionalism claims that for every speech act there is a pattern (convention) which determines its illocutionary force. To perform a felicitous speech act is to fulfil necessary and sufficient conditions for this particular speech act. Non-conventionalism criticizes the view that for every speech act there is a conventional pattern and hidden (...) conditions, which are to be fulfilled. This view maintains the conventional thesis for the so-called strict conventional speech acts (e.g. performatives), but negates using universal quantifier for so-called communicative speech acts whose aim is, in short, to express an intention and force someone to act by virtue of this intention. As in (Shapiro 2011), Phil said: in order for someone to have the power to make, change and apply rules, there has to be a rule that empowers someone to do so. This objection concerned „The First Legis- lator” only from the conventional perspective on speech acts. If it can be maintained that The First Legislator’s speech acts may be non-conventional, then Phil’s argument misses the point. Finally, I will emphasize that only lawyers analyze „the very first speech acts” whereas for philosophers, the problem of e.g. „the very first question” is less absorbing. -/- [PL] Celem niniejszego artykułu jest przedstawienie tak zwanej Aporii Phila (possibility puz- zle) przedstawionej przez Shapiro (2011) w kontekście sporu konwencjonalizm–nonkon- wencjonalizm w teorii aktów mowy. Konwencjonalizm utrzymuje, że dla każdego aktu mowy istnieje konwencja, która determinuje moc illokucyjną aktu. Wykonać w pełni for- tunny akt mowy to spełnić wystarczające i konieczne warunki określone dla danego aktu mowy. Nonkonwencjonalizm krytykuje pogląd, że dla każdego aktu mowy istnieje okre- ślona konwencja oraz ukryte warunki, które należy spełnić. Ten pogląd utrzymuje kon- wencjonalną tezę dla tak zwanych stricte konwencjonalnych aktów mowy (na przykład performatywów), ale neguje użycie dużego kwantyfikatora dla tak zwanych komunika- cyjnych aktów mowy, których celem jest, w skrócie, wyrażenie pewnej intencji i zmusze- nie kogoś poprzez jej wyrażenie do określonego postępowania. Phil, bohater historii z książki Shapiro (2011), podkreślił, iż zawsze musi istnieć reguła upoważniająca do two- rzenia prawa. Ten zarzut dotyczący „Pierwszego Legislatora” jest zasadny tylko z per- spektywy konwencjonalizmu. Jeżeli można utrzymywać, że akt mowy Pierwszego Legislatora może być nonkonwencjonalny, wtedy argument Phila jest nietrafny. Na końcu scharakteryzowany jest następujący fenomen: tylko prawnicy analizują „pierwsze akty mowy”, natomiast dla filozofów problem „pierwszego pytania” nie jest tak absorbujący. (shrink)

The paper discusses some aspects of the highly original theory of representation, developed by Descartes in his ‘Meditations’, and based on the ontological isomorphism of ideas and their material correlates. In the course of the analysis it is shown that the Cartesian theory involves unavoidable problems with discrimination or correlation of the objects in question, which is connected with the problem of constitutiveness of their modes of existence. Consequently, the conclusion of the paper is that representationism based on the isomorphistic (...) theory of representation turns out to be self-contradictory. (shrink)

The paper presents an alternative substitutional semantics for first-order modal logic which, in contrast to traditional substitutional (or truth-value) semantics, allows for a fine-grained explanation of the semantical behavior of the terms from which atomic formulae are composed. In contrast to denotational semantics, which is inherently reference-guided, this semantics supports a non-referential conception of modal truth and does not give rise to the problems which pertain to the philosophical interpretation of objectual domains (concerning, e.g., possibilia or trans-world identity). The paper (...) also proposes the notion of modality de nomine as an alternative to the denotational notion of modality de re. (shrink)

The analysis of atomic sentences and their subatomic components poses a special problem for proof-theoretic approaches to natural language semantics, as it is far from clear how their semantics could be explained by means of proofs rather than denotations. The paper develops a proof-theoretic semantics for a fragment of English within a type-theoretical formalism that combines subatomic systems for natural deduction [20] with constructive (or Martin-Löf) type theory [8, 9] by stating rules for the formation, introduction, elimination and equality of (...) atomic propositions understood as types (or sets) of subatomic proof-objects. The formalism is extended with dependent types to admit an interpretation of non-atomic sentences. The paper concludes with applications to natural language including internally nested proper names, anaphoric pronouns, simple identity sentences, and intensional transitive verbs. (shrink)
