Peter Achinstein has argued at length and on many occasions that the view according to which evidential support is defined in terms of probability-raising faces serious counterexamples and, hence, should be abandoned. Proponents of the positive probabilistic relevance view have remained unconvinced. The debate seems to be in a deadlock. This paper is an attempt to move the debate forward and revisit some of the central claims within this debate. My conclusion here will be that while Achinstein may be right (...) that his counterexamples undermine probabilistic relevance views of what it is for e to be evidence that h, there is still room for a defence of a related probabilistic view about an increase in being supported, according to which, if p > p, then h is more supported given e than it is without e. My argument relies crucially on an insight from recent work on the linguistics of gradable adjectives. (shrink)

This paper elaborates a new solution to the lottery paradox, according to which the paradox arises only when we lump together two distinct states of being confident that p under one general label of ‘belief that p’. The two-state conjecture is defended on the basis of some recent work on gradable adjectives. The conjecture is supported by independent considerations from the impossibility of constructing the lottery paradox both for risk-tolerating states such as being afraid, hoping or hypothesizing, and for risk-averse, (...) certainty-like states. The new proposal is compared to views within the increasingly popular debate opposing dualists to reductionists with respect to the relation between belief and degrees of belief. (shrink)

In this article I focus on some unduly neglected common-sense considerations supporting the view that one's evidence is the propositions that one knows. I reply to two recent objections to these considerations.

In a recent publication Travis Timmerman has claimed that sometimes it is morally permissible to not prevent something bad from happening, even if it is in one’s power to do so without sacrificing anything nearly as important.1 To defend his point, he has proposed a thought experiment and based his claims on putative common-sense morality intuitions. To aid in the subsequent discussion, Timmerman’s case is reproduced as follows.

According to the knowledge view of evidence notoriously defended by Timothy Williamson (2000), for any subject, her evidence consists of all and only her propositional knowledge (E=K). Many have found (E=K) implausible. However, few have offered arguments against Williamson’s positive case for (E=K). In this paper, I propose an argument against Williamson’s positive case in favour of (E=K). Central to my argument is the possibility of the knowledge of necessary truths. I also draw some more general conclusions concerning theorizing about (...) evidence. (shrink)

The dominant theory of judgment in 1870 was one or other variety of combination theory: the act of judgment is an act of combining concepts or ideas in the mind of the judging subject. In the decades to follow a succession of alternative theories arose to address defects in the combination theory, starting with Bolzano’s theory of propositions in themselves, Brentano’s theory of judgment as affirmation or denial of existence, theories distinguishing judgment act from judgment content advanced by Brentano’s students (...) Twardowski, Husserl and Meinong, and finally, Adolf Reinach’s addition of a linguistic dimension to the Brentano-Husserlian theory of judgment – an account of judgments as ways of doing things with words in what Reinach called ‘social acts’.

According to the good reasoning view of normative reasons, p is a reason to F, just in case p is a premise of a good pattern of reasoning. This article presents two counterexamples to the most promising version of the good reasoning view.

In this paper, I argue against recent versions of justification norms of action and practical deliberation . I demonstrate that these norms yield unacceptable results in deception cases. However, a further modification of justification norms in the light of these results appears to be ad hoc. Hence, I claim, we should reject justification norms of action and practical deliberation.

The aim of this paper is to show that the account of objective truth taken for granted by logicians at least since the publication in 1933 of Tarski’s “The Concept of Truth in Formalized Languages” arose out of a tradition of philosophical thinking initiated by Bolzano and Brentano. The paper shows more specifically that certain investigations of states of affairs and other objectual correlates of judging acts, investigations carried out by Austrian and Polish philosophers around the turn of the century, (...) formed part of the background of views that led to standard current accounts of the objectivity of truth. It thus lends support to speculations on the role of Brentano and his heirs in contemporary logical philosophy advanced by Jan Wolenski in his masterpiece of 1989 on the Logic and philosophy in the Lvov-Warsaw School.

A common assumption in contemporary debates about normative reasons is that ‘subjective’ and ‘possessed’ are two names for the same sort of reason. This paper challenges that assumption. Given our cognitive limitations, it is unsurprising that normative reasons that derive from what we know and reasons that we are in a position to use in our deliberation are not always one and the same.

According to recently popular pragmatist views it may be rational for one to believe p when one’s evidence doesn’t favour p over not-p. This may happen according to pragmatists in situations where one can gain something practically important out of believing p. In this paper I argue that given some independently plausible assumptions about the argumentative nature of philosophy and the irrelevance of bribes for good arguments, pragmatism leads to a contradiction.

In this paper I discuss the role that knowledge plays with regard to rational action. It has been recently argued that knowledge determines appropriate action. I examine this proposal, consider objections against it, and finally propose a defense of it.

In this paper I examine Williamson’s (2000) claim that all evidence is propositional. I propose to reject this claim. I give two objections to two premises of Williamson’s argument. The first is a critique of Williamson’s claim that we choose between hypotheses on the basis of our evidence. The second objection is that Williamson’s claim that evidence is an explanandum of an hypothesis leads to counter-intuitive consequences and thus is not central to what evidence is, at least on an ordinary (...) understanding.

Series of articles about Plato's dialogue "Theaetetus".

I maintain that among the main views concerning the central questions of epistemology (in particular, the question of justified belief) are evidentialism, (Pyrrhonian) scepticism and fideism. In this paper, I first present the arguments in favour of a form of evidentialism, according to which no false belief can be epistemically justified on the basis of evidence. Second, I consider the historical emergence of evidentialism during the period of the early Enlightenment. In particular, I explore the disagreement between Pierre Bayle and (...) Jean-Pierre de Crousaz, which demonstrates the emergence of the modern opposition between evidentialism and fideism. (shrink)

The aim of the article is to outline an interpretation of the philosophical understanding of the concept of the good in pre-Platonic thought. The interpretation is based on those fragments only in which the concept actually appears. As a result of the adopted assumption, the ideas of the first philosophers, i.e. Thales, Anaximander and Anaximenes, were outside the scope of the investigation, as well as those of Xenophanes, Eleatics, Empedocles, Anaxagoras and Leucippus. In the case of the first philosophical systems (...) of the pre-Platonic philosophy one notices a connection between the good and the One. It can also be found that understanding of the ‘the Best’ is depended on, and results from, ‘the good’. This is true also in Heraclitus, though, at the same time, he introduces an significant reversal in this respect, for he abolishes the absolute difference between the good and evil, and turns it to a subjective relation. The good has no ontological basis in the Democritus’ system as well, though the good’s connection with truth, accessible for every human being, allows to interpret him as arguing for an objectivistic conception of the good. The objectivity of good has subsequently been denied by the Sophists. (shrink)

According to one line of thought only propositions can be part of one’s evidence, since only propositions can serve the central functions of our ordinary concept of evidence. Ram Neta has challenged this argument. In this paper I respond to Neta’s challenge.

Series of articles about Plato's dialogue "Theaetetus".

According to a widely held view epistemic justification is a normative notion. According to another widely held assumption, epistemic justification comes in degrees. Given that gradability requires a context-sensitivity that normativity seems to lack, these two assumptions stand in tension. Giving up the assumption of gradability of justification represents a lesser theoretical cost.

The aim of the present paper is to show how Plato suggested demarcating between knowledge and other kinds of human intellectual activities. The article proposes to distinguish between two ways of such a demarcation. The first, called `the external demarcation', takes place when one differentiates between knowledge and non-knowledge, the rational and non-rational or the reasonable and non-reasonable. The second, called `internal', marks the difference within knowledge itself and could be illustrated by the difference between the so called hard and (...) soft sciences. The analyses lead tothe following conclusions. Plato refers to the whole of human intellectual activity as doxa, which is divided into two spheres. The first of them is knowledge proper whose criterion is phronesis. Three other kinds of doxa are derived from knowledge proper: 1) the traditional peri phuseos investigation (called also sophia); 2) popular doxai concerning virtues; 3) wisdom of the antilogikoi. The difference represents the external demarcation. There may be, however, a difference in the scope of knowledge proper (the internal demarcation). If the peri phuseos investigators were able to explain the field of values, the result of their investigation could be acknowledged as knowledge, although it would still be characterized as inferior due to its being based on senses. What is interesting about knowledge proper is that it is not firm and reliable but only hypothetical. It does not determine the skeptical reading of the Phaedo but it indicates that Plato has just begun his own philosophical project (which is still in progress) and the knowledge presented in the dialogue is his first positive suggestion how to solve the problem of demarcation.

Recenzio Kiraly V. Istvan Death and History c. konyverol.

The paper investigates the issue of historicity of existence and self-understanding within Gadamer’s philosophical hermeneutics. The purpose of the paper is to answer the question of how the author of Truth and method argues and interprets the unity of existence in the context of recognizing historicity as the fundamental characteristics of human being and the world. The paper shows that the historicity excludes the possibility of basing this unity on an absolute metaphysical foundation or on a reflective self-consciousness of transcendental (...) subjectivity. On the ground of philosophical hermeneutics, being-one of a human has the character of historical continuity, constituted in the process of incessant, interpretive transcending and uniting oneself. The paper shows what roles the inherited tradition and community in which one lives play in this process. Furthermore, the paper points out that for proper understanding of Gadamer’s interpretation of the unity of existence, it is necessary to take into account two issues: firstly, its departure from the concept of empty time, which is a stream of the past, present and future moments of the “Now”, in favour of ful-filled time and secondly, how general-individual relations are interpreted in philosophical hermeneutics.

Tristan Augusta von Platena jako jedyny utwór biedermeierowskiego poety znalazł się w ścisłym kanonie liryki niemieckiej. Wiersz doczekał się jednak do tej pory niewielu wnikliwych analiz; nadto zarówno starsze, jak i najnowsze propozycje interpretacyjne koncentrowały się głównie na kontekście biograficznym. Artykuł jest próbą poszerzenia istniejącej literatury przedmiotowej o nowe aspekty. Stawia on przede wszystkim pytanie o obecność mitu w strukturze utworu. Szczegółowa analiza formalna oraz rozważania o warstwie filozoficzno-estetycznej wiersza konsekwentnie ukazują indywidualny gest, z jakim autor adaptuje mityczny topos o (...) transgresywnej miłości. W tym kontekście średniowieczny motyw Tristana jawi się w wierszu wzbogacony o antyczny motyw Orfeusza. Owa oryginalna kontaminacja świadczy o antycypacji przez PIatena niemieckiej poezji modernistycznej, szczególnie zaś wskazuje na powinowactwo jego Tristana z Sonetami do Orfeusza Rilkego. (shrink)

The article discusses the nature and significance of metaphilosophical knowledge on the ground of Heidegger’s fundamental ontology. The purpose of the article is to show metaphilosophical knowledge as an essential and immanent factor of philosophical reflection. The above mentioned goal is achieved by presenting connection, occurring within the fundamental ontology, between this knowledge and theoretical philosophical reflection, both in its descriptive (defining being of philosophy) and normative (indicating how philosophical reflection should be carried out) dimension. The descriptive dimension of the (...) connection indicates a circular nature of the interactions between metaphilosophical and theoretical aspects of philosophy. The theoretical reflection on specific phenomena is, at the same time, a determination of being of the philosophy; whereas the metaphilosophical knowledge, arising from the theoretical reflection, determines character and direction of further considerations. Furthermore, the normative dimension implies that philosophical considerations should take into account this connection and deliberately practice it through systematic metaphilosophical reflection. As the source of the connection between metaphilosophical knowledge and theoretical reflection, the article indicates Heidegger’s concept of philosophy, according to which philosophy is a way of being of Dasein, consisting of ontological, conceptual interpretation of being of beings and reflecting the structures of Dasein’s existence and its pre-ontological understanding of being. -/- Keywords: fundamental ontology, metaphilosophy, philosophical reflection, grounding of philosophy, Dasein, understanding of being.

Death is a state of the total disappearance of life. Dying is a process of decay of the vital system, which ends with clinical death. In current perspectives there are several approaches to research on death and dying; these are the clinical, the humanistic, the philosophical, the psychological, the anthropological, and the sociological perspective.

According to strong pluralism, objects distinct by virtue of their modal properties can coincide. The most common objection towards such view invokes the so-called Grounding Problem according to which the strong pluralist needs to explain what the grounds are for supposed modal differences between the coincidents. As recognized in the literature, the failure to provide an answer to the Grounding Problem critically undermines the plausibility of strong pluralism. Moreover, there are strong reasons to believe that strong pluralists cannot provide an (...) explanation of the Grounding Problem. In this paper, we argue that strong pluralism can be motivated independently of the successful answer to the Grounding Problem. In order to achieve that aim, we provide a haecceitistic interpretation of strong pluralism according to which strong pluralism should be read as a position committed to the existence of primitive individuals, i.e., the individuals that have their criteria of individuation independently of their qualitative profiles. That said, we do not aim at defending haecceitism. Instead, our aim is rather modest: we want to provide a new way for the strong pluralist to supplement his view to make it more watertight.

This understanding draws upon the typology of moral subjects that makes (...) the prediction of certain kinds of action as well as oftheir consequencies possible. (shrink)

The goal of the study is to analyse the relation between students' digital learning and transversal skills, as well as between students' digital learning and virtues. In the correlative study, 73 teachers of Class 12 of general education institutions participated, filling out a questionnaire in the Google Docs environment. As a result of the theoretical analysis, the criteria for digital learning have been identified -access to digital technologies, cooperation, teachers’ digital competence and availability of activities in compliance with cognitive engagement (...) levels. The findings of the correlation analysis show that the availability of activities in compliance with cognitive engagement levels is the most important in the development of transversal skills,while in the inculcation of virtues -cooperation. The access to digital technologies has a statistically significant correlation with both transversal skills and virtues. The teachers’ digital competence promotes digital literacy and such virtues as responsibility and wisdom. The recommendations developed as part of the study include compilation and promotion of the positive experiences of digital learning at the state and local government level; continuous monitoring and feedback analysis of purposeful digital learning and educational quality at school and classroom level; the application of digital learning resources based on the offer of activities in compliance with the students' cognitive engagement levels at the personal level. Keywords:Digital technologies, cooperation, digital competence, cognitive engagement. (shrink)

In this conceptual paper, the traditional conceptualization of sustainable entrepreneurship is challenged because of a fundamental tension between processes involved in sustainable development and processes involved in entrepreneurship: the concept of sustainable business models contains a paradox, because sustainability involves the reduction of information asymmetries, whereas entrepreneurship involves enhanced and secured levels of information asymmetries. We therefore propose a new and integrated theory of sustainable entrepreneurship that overcomes this paradox. The basic argument is that environmental problems have to be conceptualized (...) as wicked problems or sustainability-related ecosystem failures. Because all actors involved in the entrepreneurial process are characterized by their epistemic insufficiency regarding the solving of these problems, the role of information in the sustainable entrepreneurial process changes. On the one hand, the reduction of information asymmetries primarily aims to enable actors to become critical of sustainable entrepreneurs’ actual business models. On the other hand, the epistemic insufficiency of sustainable entrepreneurs guarantees that information asymmetries remain as a source of new sustainable business opportunities. Three further characteristics of sustainable entrepreneurs are distinguished: sustainability and entrepreneurship-related risk-taking; sustainability and entrepreneurship-related self-efficacy; and the development of satisficing and open-ended solutions, together with multiple stakeholders.

Abstract In this chapter, we challenge the presupposed concept of innovation in the responsible innovation literature. As a first step, we raise several questions with regard to the possibility of ‘responsible’ innovation and point at several difficulties which undermine the supposedly responsible character of innovation processes, based on an analysis of the input, throughput and output of innovation processes. It becomes clear that the practical applicability of the concept of responsible innovation is highly problematic and that a more thorough inquiry (...) of the concept is required. As a second step, we analyze the concept of innovation which is self-evidently presupposed in current literature on responsible innovation. It becomes clear that innovation is self-evidently seen as (1) technological innovation, (2) is primarily perceived from an economic perspective, (3) is inherently good and (4) presupposes a symmetry between moral agents and moral addressees. By challenging this narrow and uncritical concept of innovation, we contribute to a second round of theorizing about the concept and provide a research agenda for future research in order to enhance a less naïve concept of responsible innovation.

Contrary to the tendency to harmony, consensus and alignment among stakeholders in most of the literature on participation and partnership in corporate social responsibility and responsible innovation practices, in this chapter we ask which concept of participation and partnership is able to account for stakeholder engagement while acknowledging and appreciating their fundamentally different judgements, value frames and viewpoints. To this end, we reflect on a non-reductive and ethical approach to stakeholder engagement, collaboration and partnership, inspired by the philosophy of Emmanuel (...) Levinas. We contrast a cognitive approach with an ethical approach to stakeholder engagement, collaboration and partnership, and explore four characteristics of this ethical approach. Based on the ethical approach to stakeholder engagement, collaboration and partnership, we also provide a three-stage framework for partnership formation in CSR and RI practices. (shrink)

Smart Farming Technologies raise ethical issues associated with the increased corporatization and industrialization of the agricultural sector. We explore the concept of biomimicry to conceptualize smart farming technologies as ecological innovations which are embedded in and in accordance with the natural environment. Such a biomimetic approach of smart farming technologies takes advantage of its potential to mitigate climate change, while at the same time avoiding the ethical issues related to the industrialization of the agricultural sector. We explore six principles of (...) a natural concept of biomimicry and apply these principles in the context of smart farming technologies. (shrink)

Because the techno-economic paradigm of contemporary conceptualizations of innovation is often taken for granted in the literature, this chapter opens up this self-evident notion. First, the chapter consults the work of Joseph Schumpeter, who can be seen as the founding father of the current conceptualization of innovation as technological and commercial. Second, we open up the concept by reflecting on two aspects of Schumpeter’s conceptualization of innovation, namely its destructive and its constructive aspect, based on findings in the history of (...) innovation. Finally, we synthesize our findings and propose an ontic-ontological conceptualization of innovation as ontogenetic process and outcome with six dimensions—newness, political dimension, economic dimension, temporal dimension, human dimension and risk—that moves beyond its technological and commercial orientation.

Filozofia subiektywności dotarła w XX wieku do granic swoich możliwości. Jako odpowiedź na jej ograniczenia rozmaici filozofowie podjęli próby nowego rodzaju myślenia. Takie próby to m.in. myśl dialogiczna, która pierwszy wyraz znalazła w pismach takich filozofów, jak Franz Rosenzweig, Martin Buber czy Eberhard Grisebach. Innym przykładem jest postulat powrotu do pytania o bycie Martina Heideggera. W niniejszym artykule staram się pokazać, że obie próby mają ze sobą wiele wspólnego, choć ich przedstawiciele odnosili się do siebie nawzajem raczej krytycznie, o ile (...) w ogóle to czynili. Okazuje się jednak, że myśl Martina Bubera oraz Martina Heideggera ujmują człowieka jako byt dynamiczny, który staje w obliczu nachodzącego go wezwana.

Na koniec dokonuję zestawienia i porównania wątków wspólnych obu filozofom, jak również zaznaczam różnice, które dzielą obie próby przekroczenia filozofii podmiotowości. (shrink)

The pacemaker-accumulator model provides a framework in which the results of different duration estimation tasks are commonly accounted for. Nevertheless, the model remains abstract and it does not provide proper explanations nor predictions for duration estimations in various experimental set-ups. This paper aims to address these shortcomings by explicating an experiential pacemaker-accumulator model that supplements the standard pacemaker-accumulator model with two claims. Both of them concern the role that experiences play in duration estimation tasks and are also partly supported by (...) studies not directly related to duration estimation. First, the internal responses based on which the switch between the pacemaker and the accumulator operates are the same as the neural processes that realize conscious access to experiences. Second, the processes that realize the experiences of stimuli realize the function of the pacemaker. By supplementing the standard pacemaker-accumulator model with these claims, the model affords proper explanations for the systematic errors and empirically testable predictions in duration estimations tasks. One likely consequence of the model is that the experience of duration and the duration of experience can differ. (shrink)

A stable classification of practical principles into mutually exclusive types is foundational to Kant’s moral theory. Yet, other than a few brief hints on the distinction between maxims and laws, he does not provide any elaborate discussion on the classification and the types of practical principles in his works. This has led Onora O’Neill and Lewis Beck to reinterpret Kant’s classification of practical principles in a way that would clarify the conceptual connection between maxims and laws. In this paper I (...) argue that the revised interpretations of O’Neill and Beck stem from a mistaken reading of the fundamental basis of the classification of practical principles. To show this, I first argue that Kant distinguishes between maxims and laws on the bases of validity and reality. I then argue that although a practical principle necessarily has the feature of validity, its reality in actually moving the agents to action sufficiently makes a principle a practical principle. If this is so, I argue that the classification of practical principles must be based on the extent to which they are effective in human agents. Such a classification yields us three exhaustive and mutually exclusive types namely, “maxims that are not potential laws”, “maxims that are potential laws” and “laws that are not maxims”. (shrink)

In order to make some headway on the debate about whether Kant was a constructivist, nonconstructivist, or instead defends a hybrid view that somehow entirely sidesteps these categories, I attempt to clarify the terms of the debate more carefully than is usually done. First, I discuss the overall relationship between realism and constructivism. Second, I identify four main features of Kantian constructivism in general. Third, I examine three rival versions of metanormative Kantian constructivism, what I’ll call axiological, constitutivist, and rationalist (...) constructivist. I argue that Kant is best seen as a rationalist constructivist. I conclude by arguing that although it’s a constructivist view, this reading avoids the main pitfalls of traditional Kantian constructivism. In doing so, it helps us to achieve a satisfying rapprochement between constructivist and non-constructivist readings of Kant. (shrink)

Green buildings are an integral part of the solution to the environmental challenges facing the planet. Today we use the equivalent of 1.5 Earths to meet the resource needs of everyday life and absorb the resulting wastes. This measure of our planet’s carrying capacity means that it takes Earth 18 months to regenerate what is used in only 12 months. If current trends continue, estimates suggest, by the year 2030 we will need the equivalent of two planets. Turning resources into (...) waste faster than they can be regenerated puts the planet into ecological overshoot, a clearly unsustainable condition that we all must address. The forces driving this situation are numerous. Human population has increased exponentially in the past 60 years, from about 2.5 billion in 1950 to more than 7 billion todays. Our linear use of resources, treating outputs as waste, is responsible for the toxins that are accumulating in the atmosphere, in water, and on the ground. This pattern of extraction, use, and disposal has hastened depletion of finite supplies of non-renewable energy, water, and materials and is accelerating the pace of our greatest problem—climate change.
