Objective: Vascular disorders severely impair the psycho-social status of individuals. Various laser and light systems, which have advantages and disadvantages, including the pro-yellow laser are used for the therapy of these disorders. Aim: The goal of the present study was to investigate the effectiveness and feasibility of the 577 nm pro-yellow laser for a broad range of indications including erythematelangiectatic rosacea, facial erythema, post-acne erythema, facial telangiectasis, hemangioma, genital angiokeratoma, and port wine stain nevus. Methods: A total of 98 patients (...) (25 male, 73 female) older than 15 years who were treated with the pro-yellow laser for vascular disorders at the cosmetology unit between 2017 and 2019 were retrospectively included in the study. Results: The mean rate of recovery was 100% in genital angiokeratoma, 94.4% in spider angioma, 83.3% in facial telangiectasis, 74.8% in erythematotelangiectatic rosacea, 72% in facial erythema + facial telangiectasis, and 68.3% in facial erythema. Over 60% of improvement was observed in most patients with vascular disorders. There was no significant link between the Fitzpatrick skin type and treatment success. Treatment success was significantly low in cases with nasal involvement. Conclusion: The current study concluded that pro-yellow laser is an efficient and safe laser modality that may yield satisfactory outcomes regardless of the different skin types. (shrink)

I argue—contra moderate grounding pluralists such as Kit Fine and more extreme grounding pluralists such as Jessica Wilson—that there is fundamentally only one grounding/in-virtue-of relation. I also argue that this single relation is indispensable for normative theorizing—that we can’t make sense of, for example, the debate over consequentialism without it. It follows from what I argue that there is no metaethically-pure normative ethics.

The linchpin of Williamson (2000)'s radically externalist epistemological program is an argument for the claim that no non-trivial condition is luminous—that no non-trivial condition is such that whenever it obtains, one is in a position to know that it obtains. I argue that Williamson's anti-luminosity argument succeeds only if one assumes that, even in the limit of ideal reflection, the obtaining of the condition in question and one's beliefs about that condition can be radically disjoint from one another. However, no (...) self-respecting defender of the luminosity of the mental would ever make such an assumption. Thus Williamson can only secure his controversial claims in epistemology by taking for granted certain equally controversial claims in the philosophy of mind. What emerges is that the best bet for defending an internalist epistemology against Williamson's attack is to take there to be a tight, intimate connection between (to take one example) our experiences and our beliefs upon reflection about the obtaining of those experiences, or between (to take another example) the rationality of our beliefs and our beliefs upon reflection about the rationality of those beliefs.

Once upon a time, coherentism was the dominant response to the regress problem in epistemology, but in recent decades the view has fallen into disrepute: now almost everyone is a foundationalist (with a few infinitists sprinkled here and there). In this paper, I sketch a new way of thinking about coherentism, and show how it avoids many of the problems often thought fatal for the view, including the isolation objection, worries over circularity, and concerns that the concept of coherence is (...) too vague or metaphorical for serious theoretical use. The key to my approach is to take a familiar tool from discussions of the regress problem -- namely, directed graphs depicting the support relations between beliefs -- and to use that tool in a more sophisticated manner than it is standardly employed.

Moral particularists argue that because reasons for action are irreducibly context-dependent, the traditional quest in ethics for true and exceptionless moral principles is hopelessly misguided. In making this claim, particularists assume a general framework according to which reasons are the ground floor normative units undergirding all other normative properties and relations. They then argue that there is no cashing out in finite terms either (i) when a given non-normative feature gives rise to a reason for or against action, or (ii) (...) how the reasons that are present in a given context play off each other to determine one’s overall duties. However, the conjunction of these two theses leaves particularists without a coherent notion of a reason for action: posit too much irreducible context-dependence in the behavior of reasons, and the reasons-based framework breaks down. One upshot is that the particularists’ challenge to principle-based approaches to ethics has not, at present, been successfully made out; another upshot is that perhaps the best way to formulate that challenge involves renouncing the reasons-based framework all together.

When it comes to epistemic normativity, should we take the good to be prior to the right? That is, should we ground facts about what we ought and ought not believe on a given occasion in facts about the value of being in certain cognitive states (such as, for example, the value of having true beliefs)? The overwhelming answer among contemporary epistemologists is “Yes, we should.” This essay argues to the contrary. Just as taking the good to be prior to (...) the right in ethics often leads one to sanction implausible trade-offs when determining what an agent should do, so too, this essay argues, taking the good to be prior to the right in epistemology leads one to sanction implausible trade-offs when determining what a subject should believe. Epistemic value—and, by extension, epistemic goals—are not the explanatory foundation upon which all other normative notions in epistemology rest. (shrink)

I argue that Alvin Goldman has failed to save process reliabilism from my critique in earlier work of consequentialist or teleological epistemic theories. First, Goldman misconstrues the nature of my challenge: two of the cases he discusses I never claimed to be counterexamples to process reliabilism. Second, Goldman’s reply to the type of case I actually claimed to be a counterexample to process reliabilism is unsuccessful. He proposes a variety of responses, but all of them either feature an implausible restriction (...) on process types, or fail to rule out cases with the sort of structure that generates the worry, or both.

It has been claimed that the recent wave of neuroscientific research into the physiological underpinnings of our moral intuitions has normative implications. In particular, it has been claimed that this research discredits our deontological intuitions about cases, without discrediting our consequentialist intuitions about cases. In this paper I demur. I argue that such attempts to extract normative conclusions from neuroscientific research face a fundamental dilemma: either they focus on the emotional or evolved nature of the psychological processes underlying deontological intuitions, (...) in which case the arguments rely on a blatantly fallacious inference, or they appeal to the (alleged) moral irrelevance of the factors to which deontological intuitions respond, in which case the neuroscientific results end up playing no role in the overall argument.

A quasi-sequel to "Epistemic Teleology and the Separateness of Propositions." Covers some of the same ground, but also extends the basic argument in an important way.

Suppose we grant that evolutionary forces have had a profound effect on the contours of our normative judgments and intuitions. Can we conclude anything from this about the correct metaethical theory? I argue that, for the most part, we cannot. Focusing my attention on Sharon Street’s justly famous argument that the evolutionary origins of our normative judgments and intuitions cause insuperable epistemological difficulties for a metaethical view she calls "normative realism," I argue that there are two largely independent lines of (...) argument in Street’s work which need to be teased apart. The first of these involves a genuine appeal to evolutionary considerations, but it can fairly easily be met by her opponents. The second line of argument is more troubling; it raises a significant problem, one of the most difficult in all of philosophy, namely how to justify our reliance on our most basic cognitive faculties without relying on those same faculties in a question-begging manner. However, evolutionary considerations add little to this old problem, and rejecting normative realism is not a way to solve it. (shrink)

Quasi-realists aim to account for many of the trappings of metanormative realism within an expressivist framework. Chief among these is the realist way of responding to the Euthyphro dilemma: quasi-realists want to join realists in being able to say, "It’s not the case that kicking dogs is wrong because we disapprove of it. Rather, we disapprove of kicking dogs because it’s wrong." However, the standard quasi-realist way of explaining what we are up to when we assert the first of these (...) two sentences rests on a mistaken identification of metaphysical dependence (or grounding) with counterfactual covariation. This chapter proposes a better way for expressivists to understand such sentences, on which they serve to express complex states of mind in which an attitude bears a relation of psychological dependence (or basing) to another state of mind. It is argued that this proposal is a natural, versatile, and fruitful approach for expressivists to take that helps them secure the first half of the Euthyphro contrast—but at the cost of making it difficult to see how expressivists can make sense of that contrast’s second half.

After summarizing the essential details of Anil Gupta’s account of perceptual justification in his book _Empiricism and Experience_, I argue for three claims: (1) Gupta’s proposal is closer to rationalism than advertised; (2) there is a major lacuna in Gupta’s account of how convergence in light of experience yields absolute entitlements to form beliefs; and (3) Gupta has not adequately explained how ordinary courses of experience can lead to convergence on a commonsense view of the world.

This study focuses on the ideas of Antonio Negri and Michael Hardt, the most influential thinkers of recent period, about the concepts of the Empire, Multitude and Biopolitical production. These concepts being at the center of contemporary political discussions problematise the ideaitonal foundations of the idea of Empire evaluated as a new form of sovereignty, the economic transformation in the contemporary capitalism and the new form of subjectivity in this age. To Negri and Hardt, Empire is seen as a logic (...) of network operating at global level and a new logic of sovereignty and governance going beyond the political boundaries of nation states as form of sovereignty. In this regard, multitude is evaluated as a collective and joint social subject against the power and command forms of empire. As for biopolitical production, it is defined as the production of life in which feelings, symbols, communication and cooperation go beyond the understanding that centers the production of tangible goods within the capitalist production and work organization. These three concepts draw an important framework in terms of understanding the economic, political transformation of the contemporary world. In this study, it was aimed at interpreting the nature of global changes brought forward by the Negri and Hardt thought within the boundaries of these three concepts. (shrink)

This study focuses on the concept of people developed by Ernesto Laclau and Chantal Mouffe in the context of radical theories of democracy and populism. People is defined as a subjectivity established as a contingency in the conflictual environment of politics. The construction of the people is a condition of the existence of populist politics as a form of subject that enables the division of politics and social into two camps in the form of friend/enemy and the formation of antagonisms. (...) The article seeks to answer the question of how to create a political order in Laclau and Mouffe's conception of the people in a pluralistic society, in order to cleanse politics from antagonistic (struggle between enemies) relations and transform it into agonistic (struggle between adversaries) relations, despite the danger of eliminating each other through a friend-enemy relationship. In this study, it will be discussed whether the antagonism that constitutes the foundation of politics and society is indestructible and whether it is a subject figure in which the people is organized as a counter-hegemonic subject against certain kinds of antagonisms and whether those who are partners can come together agonistically.

This work focuses on the analysis of Paul Virilio, an important representative of the Contemporary French Thought, pertaining to society. Virilio sees modern society as the transformation of time-space relations within the context of the proliferation of speed-producing vehicles. The proliferation of speed and speed producing tools has brought about the end of space and also has reconstructed time as accelerated time. Speed is seen as a dominant logic in the organization of economic, political, military, social and urban spheres. In (...) other words, modern society is built on the basis of a new logic of speed in which not only merely economic transformations but also political, military, spatial and technological changes occur. According to Virilio, the modern age brought a model of society based on movement through the proliferation of speedgenerating tools. He defines the transformations in modern society with the concept of "dromology" (speed science). This approach evaluates the speed as a central category in formation and development of all socities. To Virilio, speed is an important tool determining both power and controlling means and the distribution of money and wealth. The study discusses the transformation of the speed, which is questioned by Virilio by means of such concepts as dromologic revolution, dromologic progress, dromocratic society, within the social and historical processes as well as the change of military and spatial organizations within the mdoernity. The study, in a way, draws a framework that aims to understand the new social organization of information, information, money and labor flows caused by globalization as a radical dromologic situation.

Epidemics are situations that ruin the functioning of the social due to their characteristics concerning the disruption of the usual pace of daily life and reshaping of human actions and social encounters. In terms of its impact, the Covid-19 global epidemic has brought about changes in a series of daily life practices, from business and working life to public encounters, from education and health services to human relations, public encounters and the organization of the society on a time-space scale, based (...) on repetition. Everyday life is directly related to the establishment of the society depending on the repeatability of day-to-day activities as a routine of social relations and public encounters on a certain time-space scale. This study discusses how the society, which became possible as a result of the repetitive structuring of human actions with the Covid-19 epidemic, has transformed through new routines, new habits, new time-space practices and new public encounters.

In her book, Illness as Metaphor, Susan Sontag focuses on metaphors and myths on diseases such as cancer and tuberculosis, which occur in different historical periods. Sontag argues that the metaphors produced related to illness overhaul illness and the things that define illness now have become metaphors produced related to them rather than their concrete and physical aspects. Illness becomes not just an illness, but a phenomenon defined by evil, mystery, fear, evil, madness, passions, wealth and poverty, temporal loginess or (...) speed, and a set of metaphors or myths that are spatially identified with the space. Metaphors and myths turn into means of socially stigmatizing the illness itself rather than giving a meaning to illness. The disease literally turns into a situation that needs to be hidden in order to avoid social stigma. The explanation of mass diseases through metaphors and myths has been seen since ancient times and this understanding of mass diseases continues to exist today. As a matter of fact, the Covid-19 pandemic has also ceased to be the subject of only medical science since it first emerged, and it has turned into an issue that concerns many areas from politics to economics, from sociology to psychology. The metaphors generated on the Covid-19 disease, which we have witnessed its reflections in many areas from the discourses of daily life to the discourse of politicians, from art to literature, have a similar function with the metaphors attributed to diseases like cancer and tuberculosis that Sontag discussed. Covid-19 is not only seen as a disease, but as a disease defined by a series of metaphors such as mysterious, evil, invisible enemy, insidious danger, and democratic virus. The metaphors generated on the disease cause the struggle against the disease itself to be explained with various metaphors. The metaphors derived from Covid-19 such as "invisible enemy" and "biological war" cause the struggle against it to be turned into a military terminology, and the metaphor of "Chinese virus" is a means of social stigmatization / marginalization by racializing the virus directly. This study tackles the issue of how Covid-19, which is the subject of medical science, has become the subject of unscientific myths and metaphors attributed to the disease, and that the disease is perceived through metaphors rather than itself in the context of Susan Sontag's thought. In the study, answers for the questions of what kind of effects appeared due to the stigmatizing power of metaphors derived from the Covid-19 and whether the metaphors are the outcomes of the strategy for coping with the pandemic will be sought.

The work described in this report is motivated by the desire to test the expressive possibilities of action language C+. The Causal Calculator (CCalc) is a system that answers queries about action domains described in a fragment of that language. The Zoo World and the Traffic World have been proposed by Erik Sandewall in his Logic Modelling Workshop—an environment for communicating axiomatizations of action domains of nontrivial size. -/- The Zoo World consists of several cages and the exterior, gates between (...) them, and animals of several species, including humans. Actions in this domain include moving within and between cages, opening and closing gates, and mounting and riding animals. The Traffic World includes vehicles moving continuously between road crossings subject to a number of restrictions, such as speed limits and keeping a fixed safety distance away from other vehicles on the road. We show how to represent the two domains in the input language of CCalc, and how to use CCalc to test these representations. (shrink)

We present a simple example that disproves the universality principle. Unlike previous counter-examples to computational universality, it does not rely on extraneous phenomena, such as the availability of input variables that are time varying, computational complexity that changes with time or order of execution, physical variables that interact with each other, uncertain deadlines, or mathematical conditions among the variables that must be obeyed throughout the computation. In the most basic case of the new example, all that is used is a (...) single pre-existing global variable whose value is modified by the computation itself. In addition, our example offers a new dimension for separating the computable from the uncomputable, while illustrating the power of parallelism in computation. (shrink)

The purpose of this study is to present how ancient and modern thinkers describe politics and to discuss reasons for differences seen in these definitions. In the ancient period, the identification of human being as a political entity by nature caused politics to be seen as the most supreme of all human activities. For the ancient thinkers, politics is conceptualized as a pluralist area in which the common issues are discussed by equals and also which excludes inequality. Ancient thinker Aristotle (...) says that the purpose of politics is “good life”. However, modern political thought which began with Machiavelli identified politics with the concepts of force, power and violence. Politics is defined by Machiavelli and his successors as the legitimate organization of physical violence, the distribution of power, value and resources by authority. While in the Ancient Greece violence is excluded from the public-political sphere, It has become one of the central concepts defining the political society in the modern world. While the human being was defined as a political entity (zoon politikon) in the ancient period, it is usually seen as an economic entity (homo economicus) in the modern period. For the ancients good life means a life that is dedicated to politics; nevertheless, it has been often associated with econo- mic activity by the moderns. This study argues that the main difference between the political definitions of ancients and moderns stem from differences between their perspectives about the aim of human and human life. (shrink)

With the 21st century, we are witnessing the mass spread of the communication technologies and social media revolution. Interactive networks built on a global scale have led to the formation of a virtual world of reality that is connecting the whole world. With the global spread of communication networks, the question of whether social media points to a new public sphere has been raised. Social media applications such as Facebook, Twitter and Instagram are nowadays seen as a place where political (...) campaigns are carried out, causing the destruction of authoritarian regimes, organizing global protests and innovation culture, and discussing political, social and cultural changes. What gives social media a similar quality to the agora of Ancient Greek city-states is the characteristic of been a place where citizens come together and talk about issues that are considered to be public, eventhough in a virtual reality. This work, following the Arendtian sense, discusses whether social media really is a place where public issues are discussed, common ideas are produced and transparency prevails. In her work "The Human Condition", Arendt makes a fundamental distinction between private and public sphere based on human activities. By conceiving the activities that she describes as labour and work in relation to the private sphere, Arendt tackles the activity of action through linking it to public sphere. Arendt defines the public sphere as a sphere of freedom and a political sphere. The public sphere consists of equal people without hierarchy, who come together with their completely free will. According to Arendt, the condition for the public sphere to be possible is transparency and commonality. Firstly; it has a wide transparency in the sense that something have to be seen and heard by others, and the second is that it points to a common world that belongs to everyone, except for the part that is privately owned. Considering the public sphere in relation to the transparency not a direct transfer of things that happen in the private or intimate sphere. It is precisely related to the fact that something pertaining to the private exhibits a presence within the world of public and the fact that the private acquires a public chatacter. This does not mean that the public sphere is a sphere in which the private and intimate are directly transferred. According to Arendt, leading a private life as a whole will lead to the lack of what is necessary to be a true person. It also leads to the lack of a common world that unites and separates them. Arendt thinks that with the modern period, what belongs to the purely private and intimate sphere expands and causes the collapse of the public. The collapse of the public sphere in the modern period; It has caused both the loss of difference and interaction and the emergence of individuals who are increasingly alike, unable to think and act. In this kind of society, action has left its place to behavior, difference to standartization and thought to obedience. Arendt sees the public sphere as a sphere where public affairs are discussed, while the private sphere is a sphere where intimate and private activities take place. Arendt argues that with modern society the distinction between public and private has became indistinct , and as a third sphere, the social sphere has swallowed up both the public and the private. The social sphere has removed the distinction between the public transparency and commonality of the public and the privacy of the private sphere and activities. This study considers social media as a sphere where public issues are discussed. It also dıscusses the private sphere events and the most intimate issues. It claims that social media is not a new public sphere as it is cosidered, but it is a social sphere in which the distinction between private and public in the Arendtian sense is become indistinct. In this context, the study seeks to answer the following questions: How does the distinction between public and private spheres, which is central in Arendt's thought, look like in today’s world? Is it possible to talk about a public sphere in the modern age? Can social media be considered as a public sphere? Or is social media a sphere of freedom and a political sphere? Does social media allow discussions on public issues? Is social media a non-hierarchical nature open to the free participation of everyone, difference and plurality? (shrink)

Selim Berker argues that particularists do not have a coherent notion of reasons for action because they cannot show that contributory reasons always contribute to overall reason or moral judgments in accordance with their valence. I argue that Berker fails to demonstrate that particularists cannot show this to be the case. He also wrongly assumes that they need to know this to be the case to legitimately speak of reasons for action. Furthermore, Jonathan Dancy’s account of practical reasoning explains how (...) particularists can legitimately speak of reasons for action while claiming that reasons sometimes make contributions contrary to their valence.

Selim Berker argues that epistemic consequentialism is pervasive in epistemology and that epistemic consequentialism is structurally flawed. is incorrect, however.

According to a widely held view of the matter, whenever we assess beliefs as ‘rational’ or ‘justified’, we are making normative judgements about those beliefs. In this discussion, I shall simply assume, for the sake of argument, that this view is correct. My goal here is to explore a particular approach to understanding the basic principles that explain which of these normative judgements are true. Specifically, this approach is based on the assumption that all such normative principles are grounded in (...) facts about values, and the normative principles that apply to beliefs in particular are grounded in facts about alethic value––a kind of value that is exemplified by believing what is true and not believing what is false. In this chapter, I shall explain what I regard as the best way of interpreting this approach. In doing so, I shall also show how this interpretation can solve some problems that have recently been raised for approaches of this kind by Selim Berker, Jennifer Carr, Michael Caie, and Hilary Greaves.

Normative discourse frequently involves explanation. For example, we tell children that hitting is wrong because it hurts people. In a recent paper, Selim Berker argues that to account for this kind of explanation, expressivists need an account of normative grounding. Against this, I argue that expressivists should eschew grounding and stick to a more pragmatic picture of explanation, one that focuses on how we use explanatory speech acts to communicate information. I propose that the standard form of a normative explanation (...) is a generalizing explanation, one which shows a particular moral injunction to follow from a more general injunction. I use Marc Lange’s account of unifying explanations in mathematics as a model for the canonical form of a normative explanation, but also to establish that logical entailment can be explanatory, so long as premises entailing the conclusion answer appropriately to our interests. An additional upshot of the resulting view is that it paves the way for a purely metaphysical solution to the problem of creeping minimalism. Quasireal properties are those that, unlike real properties, stand outside of the metaphysical hierarchy of grounding relations. (shrink)

Moral error theory is comprised of two parts: a denial of the existence of objective values, and a claim about the ways in which we attempt to make reference to such objective values. John Mackie is sometimes presented as endorsing the view that we necessarily presuppose such objective values in our moral language and thought. In a series of recent papers, though, Victor Moberger (2017), Selim Berker (2019), and Michael Ridge (2020) point out that Mackie does not seem to commit (...) himself to this view. They argue that Mackie thinks this reference to objective values can, and perhaps should, be detached from our moral statements and judgments. In this paper, I argue that Moberger, Berker, and Ridge are right to point out that Mackie stops short of claiming a necessary connection between moral language and a commitment to objective values, but that he does not endorse the contrary claim either. Instead, Mackie stays neutral on the question whether it is possible to assert moral statements or make moral judgments without presupposing objective value. This is because he does not need to take a position on this matter. Mackie only engages with the conceptual analysis of moral language and thought to the extent required to achieve his argumentative goals: he wants to reject revisionary analyses of moral language and to refute the idea that we can assume moral truths to be in alignment with ordinary moral language.

This paper aims to show that Selim Berker’s widely discussed prime number case is merely an instance of the well-known generality problem for process reliabilism and thus arguably not as interesting a case as one might have thought. Initially, Berker’s case is introduced and interpreted. Then the most recent response to the case from the literature is presented. Eventually, it is argued that Berker’s case is nothing but a straightforward consequence of the generality problem, i.e., the problematic aspect of the (...) case for process reliabilism (if any) is already captured by the generality problem.
