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.

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.

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.

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.

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.

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.

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.

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)

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.

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

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.

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.

There are notorious differences between the Jesuit theology of Gracián’s Humanism and the Pascalian theology of grace of the Colombian thinker Nicolás Gómez Dávila. In addition, Gómez Dávila criticizes Spanish Baroque when he compares it with other literatures. However, the virtuous hero of Gracián and the philosophical way of life of the Colombian thinker are connected. Both philosophies develop a mundane ethic that solves a puzzle: how the human spirit can access transcendence through the dark labyrinths of earthly difficulties.

The purpose of the article is to explain the political philosophy of Nicolás Gó- mez Dávila, emphasizing his particular way of understanding the relationship between theory and political action. For Gómez Dávila, the ‘authentic reactionary’ –as he calls himself– is the opposite of the committed intellectual, and therefore his political postulates do not encourage and should not encourage any transformation of society or any struggle in the political arena. Consistent with Gómez Dávila’s thesis, the only political action left to the (...) authentic reactionary in our time is the discreet praxis of reading alone, dialogue with few friends, and fragmentary writing as a form of expression close to silence.

The aim of the article is to show a new interpretation of Nicolás Gómez Dávila’s philosophy by means of an analysis of his early work Textos I. In the article it is demonstrated that the ten essays of this book, apparently dispersed, are connected thematically around the big questions of philosophical anthropology. They also can be described as phenomenological exercises from the methodological point of view. A philosophical hermeneutic of the Dávila’s work, attending different moments of his philosophy and rejecting (...) the will to find a total system of thinking in a fragmented work, must be put forward.

In 2009, we celebrated the bicentennial of the birth of Charles Darwin and the sesquicentennial of the publication of his book The Origin of Species. This seems to be a good opportunity to evaluate the importance of Darwin’s work for the social sciences, mainly for philosophical anthropology. The aim of this paper is to discuss the traditional anthropocentric conceptions of man, which consider our biological species to be exceptional – qualitatively higher than other living organisms. Over the course of the (...) 20th century, philosophers have argued for the claim in a number of ways: man is supposed to be the only animal capable of laughter, love, thought or language. It has also been claimed that only members of Homo sapiens have free will, morality or religion. The paper refutes these arguments on the basis of contemporary studies by M. Davila Ross, H. Fischer, K. Arnold, K. Zuberbühler, G. Konopka, B. Libet, F. De Waal, M. Bekoff, P. Boyer, B. Hood, G. Paul and others. The author argues that the only differences between man and other animals are quantitative, and therefore the nature of humans should be studied using the methods of naturalized philosophy, with respect to the natural sciences.

The aim of the research is to show the need to defend the prosaic reconfiguration of humanity that we set up every day by using temporary resources. This implies to discuss the overvalued achievements of the philosophies that advocate a direct encounter with our raw reality, or that defend an absolutist project of construction of the being of man that ends by suffocating him instead of offering any kind of salvation. The hypothesis states that the possibility of existence of man, (...) understood as the existence of a sense of the human — and, consequently, of a world with a meaning for man — depends on that prosaic configuration of our home that we have to reenact every morning. The development of meaningful worlds — that exist only as long as man exists, and vice versa — is achieved through symbolic resources, such as the metaphor or the concept. This allows us to replace one thing with another, merrily deferring the direct encounter with our constitutive ontological problematicity. To think man's reality is philosophically bearable only through metaphors and concepts, that is, by spreading a mundane prose that does not, that cannot and that should not come to an end. This in spite of the vocation for epic heroism that characterizes philosophy, and in spite of its temerarious impulse to dive into the depths in order to face what we directly cannot speak of, not without becoming speechless.

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)

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.

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.

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.

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.

The aim of the present article is to accomplish two things. The first is to show that given some further plausible assumptions, existing challenges to the indispensability of knowledge in causal explanation of action fail. The second is to elaborate an overlooked and distinct argument in favor of the causal efficacy of knowledge. In short, even if knowledge were dispensable in causal explanation of action, it is still indispensable in causal explanation of other mental attitudes and, in particular, some reactive (...) attitudes and factive emotions. Taking into account this sort of causal efficacy in determining which mental states are genuine mental states opens up new perspectives for defending the view that knowledge is the most general factive and genuine mental state.

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)

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)

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.

Background: Depression (major depressive disorder) is a common and serious medical illness that negatively affects how you feel, the way you think and how you act. Fortunately, it is also treatable. Depression causes feelings of sadness and/or a loss of interest in activities once enjoyed. It can lead to a variety of emotional and physical problems and can decrease a person’s ability to function at work and at home. Depression affects an estimated one in 15 adults (6.7%) in any given (...) year. And one in six people (16.6%) will experience depression at some time in their life. Depression can strike at any time, but on average, first appears during the late teens to mid-20s. Women are more likely than men to experience depression. Some studies show that one-third of women will experience a major depressive episode in their lifetime. Objectives: The main goal of this expert system is to get the appropriate diagnosis of disease and the correct treatment and give the appropriate method of treatment through several tips that concern the disease and how to treat it and we will see it through the application on the expert system. Methods: in this paper the design of the proposed Expert System which was produced to help Psychologist in diagnosing depression disease through its symptoms such as: a loss of energy, a change in appetite, sleeping more or less, anxiety, reduced concentration, indecisiveness, restlessness, feelings of worthlessness, guilt or hopelessness and thoughts of self-harm or suicide. The proposed expert system presents an overview about depression disease is given, the cause of diseases is outlined and the treatment of disease whenever possible is given out. SL5 Object Expert System language was used for designing and implementing the proposed expert system. Results: The proposed depression disease diagnosis expert system was evaluated by psychologist students and they were satisfied with its performance. Conclusions: The Proposed expert system is very useful for psychologist, patients with depression and newly graduated psychologist. (shrink)

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.

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.

Abstract: The COVID-19 pandemic has posed unprecedented challenges to global healthcare systems, necessitating accurate and timely forecasting of cases for effective mitigation strategies. In this research paper, we present a novel approach to predict COVID-19 cases using Artificial Neural Networks (ANNs), harnessing the power of machine learning for epidemiological forecasting. Our ANNs-based forecasting model has demonstrated remarkable efficacy, achieving an impressive accuracy rate of 97.87%. This achievement underscores the potential of ANNs in providing precise and data-driven insights into the dynamics (...) of the pandemic. However, this paper underscores the critical importance of a comprehensive evaluation beyond accuracy, including metrics such as sensitivity, specificity, and the area under the ROC curve (AUC-ROC), to assess the model's performance robustness. The research paper offers detailed insights into the architecture of the ANN model, encompassing critical hyperparameters, data preprocessing techniques, and regularization strategies employed to optimize model accuracy. Ethical considerations surrounding data privacy and potential biases within the COVID-19 dataset are also addressed. While the achieved accuracy is a significant milestone, this study underscores the dynamic and evolving nature of the pandemic, necessitating continuous model refinement and validation. Furthermore, it emphasizes the importance of considering false positives and false negatives in the context of public health decision-making. In conclusion, this research contributes to the arsenal of tools available for pandemic management by showcasing the potential of ANNs in COVID-19 case forecasting. It encourages ongoing exploration and adaptation of predictive models to enhance their applicability in real-world public health scenarios, ultimately contributing to more effective pandemic control and response efforts.

By trying to translate sign language using artificial intelligence algorithms, we focused in this paper using transfer learning technique based on deep learning by utilizing a MobileNet algorithm and compared it with the previous paper results[10a], where we get in the Mobilenet algorithm on the degree of Accuracy 93,48% but the VGG16 the accuracy was 100% For the same number of images (43500 in the dataset in size 64*64 pixel ) and the same data split training data into training dataset (70%) and validation dataset(15%) and testing dataset(15%) and 20 epoch .

The study aimed to identify the role of administrative procedures and systems in enhancing the performance of the educational institutions in the Islamic University in Gaza. To achieve the research objectives, the researchers used the analytical descriptive approach to collect information. The researchers used the questionnaire distributed to three categories of employees at the Islamic University (senior management, faculty members, their assistants and members of the administrative board). A random sample of 314 employees was selected and 276 questionnaires were retrieved (...) with a recovery rate of 88.1%. The Statistical Analysis Program (SPSS) was used to enter process and analyze data. The results of the research showed a positive role for the administrative procedures and systems in enhancing the performance of the Islamic University from the point of view of the members (senior management, teaching staff and their assistants and the administrative body), where the relative weight of all the paragraphs (73.728%). The analysis of the results revealed that the administrative procedures at the Islamic University in Gaza are used to an acceptable degree. The relative weight of all the paragraphs is 70%. This indicates a relationship between administrative procedures and regulations and the performance of the Islamic University in the Gaza Strip. The study found that there was a good degree of approval from the sample regarding the administrative procedures and their relationship to the job performance. There exist a sufficient degree of powers to the deans and department managers to carry out their tasks, with the use of plans as control tools. And that there are rules and procedures provided for decision-making in the University Council. It also has full powers to manage the university to improve the teaching and learning environment. The researchers also recommended a number of recommendations, including the need to follow up on the procedures and systems of management and update them continuously in the light of changes that may occur and to ensure the existence of a strong system of electronic information systems within the university. There is a need to provide mechanisms for obtaining information about the surrounding external environment, and effective mechanisms to provide managers with the necessary information in a timely manner. The importance of providing channels of communication that enables staff to communicate information about any violations and breaches. The study also recommended the follow-up, review, procedures and administrative systems, and work to modify them in line with the mission of the university and the objectives that the university seeks to reach.

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. Dlatego też analizuję najpierw koncepcję Martina Heideggera z okresu Bycia i czasu, następnie przedstawiam myślenie Martina Bubera, głównie w oparciu o jego traktat Ja i Ty. Na koniec dokonuję zestawienia i porównania wątków wspólnych obu filozofom, jak również zaznaczam różnice, które dzielą obie próby przekroczenia filozofii podmiotowości. (shrink)
