In this paper, we investigate how the interactions of a robot with its environment can be used to create concepts that are typically represented by verbs in language. Towards this end, we utilize the notion of affordances to argue that verbs typically refer to the generation of a specific type of effect rather than a specific type of action. Then, we show how a robot can form these concepts through interactions with the environment and how humans can use these concepts (...) to ease their communication with the robots. We demonstrate that iCub, a humanoid robot, can use the concepts, which it has developed, to to understand what a human performs, perform multi-step planning for reaching a goal state as well as to specify a goal to the robot using symbolic descriptions.

White, Christensen, and Feldman have recently endorsed uniqueness, the thesis that given the same total evidence, two rational subjects cannot hold different views. Kelly, Schoenfield, and Meacham argue that White and others have at best only supported the weaker, merely intrapersonal view that, given the total evidence, there are no two views which a single rational agent could take. Here, we give a new argument for uniqueness, an argument with deliberate focus on the interpersonal element of the thesis. Our argument (...) is that the best explanation of the value of promoting rationality is an explanation that entails uniqueness. (shrink)

This paper begins by raising a puzzle about what function our use of the word ‘rational’ could serve. To solve the puzzle, I introduce a view I call Epistemic Communism: we use epistemic evaluations to promote coordination among our basic belief-forming rules, and the function of this is to make the acquisition of knowledge by testimony more efficient.

A Boltzmann Brain, haphazardly formed through the unlikely but still possible random assembly of physical particles, is a conscious brain having experiences just like an ordinary person. The skeptical possibility of being a Boltzmann Brain is an especially gripping one: scientific evidence suggests our actual universe’s full history may ultimately contain countless short-lived Boltzmann Brains with experiences just like yours or mine. I propose a solution to the skeptical challenge posed by these countless actual Boltzmann Brains. My key idea is (...) roughly this: the skeptical argument that you’re one of the Boltzmann Brains requires you to make a statistical inference, but the Principle of Total Evidence blocks us from making the inference. I discuss how my solution contrasts with a recent suggestion, made by Sean Carroll and David Chalmers, for how to address the skeptical challenge posed by Boltzmann Brains. And I discuss how my solution handles certain relevant concerns about what to do when we have higher-order evidence indicating that our first-order evidence is misleading. (shrink)

In section 1, I develop epistemic communism, my view of the function of epistemically evaluative terms such as ‘rational’. The function is to support the coordination of our belief-forming rules, which in turn supports the reliable acquisition of beliefs through testimony. This view is motivated by the existence of valid inferences that we hesitate to call rational. I defend the view against the worry that it fails to account for a function of evaluations within first-personal deliberation. In the rest of (...) the paper, I then argue, on the basis of epistemic communism, for a view about rationality itself. I set up the argument in section 2 by saying what a theory of rational deduction is supposed to do. I claim that such a theory would provide a necessary, sufficient, and explanatorily unifying condition for being a rational rule for inferring deductive consequences. I argue in section 3 that, given epistemic communism and the conventionality that it entails, there is no such theory. Nothing explains why certain rules for deductive reasoning are rational. (shrink)

In this paper, I explore a question about deductive reasoning: why am I in a position to immediately infer some deductive consequences of what I know, but not others? I show why the question cannot be answered in the most natural ways of answering it, in particular in Descartes’s way of answering it. I then go on to introduce a new approach to answering the question, an approach inspired by Hume’s view of inductive reasoning.

Whereas Bayesians have proposed norms such as probabilism, which requires immediate and permanent certainty in all logical truths, I propose a framework on which credences, including credences in logical truths, are rational because they are based on reasoning that follows plausible rules for the adoption of credences. I argue that my proposed framework has many virtues. In particular, it resolves the problem of logical omniscience.

The main question of this paper is: how do we manage to know what our own degrees of belief are? Section 1 briefly reviews and criticizes the traditional functionalist view, a view notably associated with David Lewis and sometimes called the theory-theory. I use this criticism to motivate the approach I want to promote. Section 2, the bulk of the paper, examines and begins to develop the view that we have a special kind of introspective access to our degrees of (...) belief. I give an initial assessment of the view by examining its compatibility with leading theories of introspection. And I identify a challenge for the view, and explain why I'm optimistic that the view can overcome it. (shrink)

The Problem of Epistemic Regress in Contemporary Epistemology and The Adequacy of Improved Solution Suggestions One of the main problems of epistemology; whether our beliefs about the world are correct or not, that is to say, it’s the problem of whether we have suitable reasons or not to think that we have the enough knowledge. The value of our beliefs and its epistemic justifiability are being examined through this problem. In this respect, Undoubtedly; one of the greatest problem of contemporary (...) epistemology is the problem of epistemic regress that is a problem of justification. On the other hand the solution suggestions developed for this problem, which is shown as a threat factor for the knowledge in point, don’t seem sufficient. In this article, the problem of epistemic regress which is emerging in the contemporary period will be discussed by examining the perspectives of tradition and contemporary epistemology. Four different and similar basic approaches that arise resulting from the problem of regress solution proposals brought by foundationalism, compatibilism, externalism and internalism will be analyzed.

I object to Markos Valaris’s thesis that reasoning requires a belief that your conclusion follows from your premisses. My counter-examples highlight the important but neglected role of suppositional reasoning in the basis of so much of what we know.

True beliefs and truth-preserving inferences are, in some sense, good beliefs and good inferences. When an inference is valid though, it is not merely truth-preserving, but truth-preserving in all cases. This motivates my question: I consider a Modus Ponens inference, and I ask what its validity in particular contributes to the explanation of why the inference is, in any sense, a good inference. I consider the question under three different definitions of ‘case’, and hence of ‘validity’: the orthodox definition given (...) in terms of interpretations or models, a metaphysical definition given in terms of possible worlds, and a substitutional definition defended by Quine. I argue that the orthodox notion is poorly suited to explain what's good about a Modus Ponens inference. I argue that there is something good that is explained by a certain kind of truth across possible worlds, but the explanation is not provided by metaphysical validity in particular; nothing of value is explained by truth across all possible worlds. Finally, I argue that the substitutional notion of validity allows us to correctly explain what is good about a valid inference. (shrink)

What accounts for how we know that certain rules of reasoning, such as reasoning by Modus Ponens, are valid? If our knowledge of validity must be based on some reasoning, then we seem to be committed to the legitimacy of rule-circular arguments for validity. This paper raises a new difficulty for the rule-circular account of our knowledge of validity. The source of the problem is that, contrary to traditional wisdom, a universal generalization cannot be inferred just on the basis of (...) reasoning about an arbitrary object. I argue in favor of a more sophisticated constraint on reasoning by universal generalization, one which undermines a rule-circular account of our knowledge of validity. (shrink)

This paper looks at three ways of addressing probabilism’s implausible requirement of logical omniscience. The first and most common strategy says it’s okay to require an ideally rational person to be logically omniscient. I argue that this view is indefensible on any interpretation of ‘ideally rational’. The second strategy says probabilism should be formulated not in terms of logically possible worlds but in terms of doxastically possible worlds, ways you think the world might be. I argue that, on the interpretation (...) of this approach that lifts the requirement of certainty in all logical truths, the view becomes vacuous, issuing no requirements on rational believers at all. Finally, I develop and endorse a new solution to the problem. This view proposes dynamic norms for reasoning with credences. The solution is based on an old proposal of Ian Hacking’s that says you’re required to be sensitive to logical facts only when you know they are logical facts. (shrink)

We give a Bayesian argument showing that, even if your total empirical evidence confirms that you have zillions of duplicate Boltzmann Brains, that evidence does not confirm that you are a Boltzmann Brain. We also try to explain what goes wrong with several of the sources of the temptation for thinking that such evidence does have skeptical implications.

I critically examine an evolutionary debunking argument against moral realism. The key premise of the argument is that there is no adequate explanation of our moral reliability. I search for the strongest version of the argument; this involves exploring how ‘adequate explanation’ could be understood such that the key premise comes out true. Finally, I give a reductio: in the sense in which there is no adequate explanation of our moral reliability, there is equally no adequate explanation of our inductive (...) reliability. Thus, the argument that would debunk our moral views would also, absurdly, debunk all inductive reasoning. (shrink)

We can make new progress on stalled debates in epistemology if we adopt a new practical approach, an approach concerned with the function served by epistemic evaluations. This paper illustrates how. I apply the practical approach to an important, unsolved problem: the problem of forgotten evidence. Section 1 describes the problem and why it is so challenging. Section 2 outlines and defends a general view about the function of epistemic evaluations. Section 3 then applies that view to solve the problem (...) of forgotten evidence. (shrink)

This article focuses on recent discussions about holobionts and evolutionary individuality to evaluate the merits of integrative pluralism. I argue that integrative pluralism is the wrong approach to take when it comes to holobiont research because integrative pluralism is not liberal enough to accommodate both single-species and multispecies individuals. I conclude by suggesting two points. First, a pluralistic view helps us better understand holobiont research. Second, the case of holobionts helps us develop a better account of scientific pluralism.

This paper aims to accessibly present, and then critique, Hugo Mercier and Dan Sperber's recent proposals for the evolutionary function of human reasoning. I take a critical look at the main source of experimental evidence that they claim as support for their view, namely the confirmation or “myside” bias in reasoning. I object that Mercier and Sperber did not adequately argue for a claim that their case rests on, namely that it is evolutionarily advantageous for you to get other people (...) to believe whatever you antecedently believe. And I give my own argument that this claim is false. I also critically look at their suggestion that reasoning has a justificatory function, functioning as a kind of reputation management tool. I argue this suggestion does not amount to a plausible evolutionary function. (shrink)

After briefly expositing some fundamental issues in current debates about apriority, I go on to critically examine meaning-based explanations of how we acquire apriori justification.

Rationalism, my target, says that in order to have perceptual knowledge, such as that your hand is making a fist, you must “antecedently” (or “independently”) know that skeptical scenarios don’t obtain, such as the skeptical scenario that you are in the Matrix. I motivate the specific form of Rationalism shared by, among others, White (Philos Stud 131:525–557, 2006) and Wright (Proc Aristot Soc Suppl Vol 78:167–212, 2004), which credits us with warrant to believe (or “accept”, in Wright’s terms) that our (...) senses are reliably veridical, where that warrant is one we enjoy by default, that is, without relying on any evidence or engaging in any positive argument. The problem with this form of Rationalism is that, even if you have default knowledge that your senses are reliable, this is not adequate to rule out every kind of skeptical scenario. The problem is created by one-off skeptical scenarios, scenarios that involve a highly reliable perceiver who, by a pure fluke, has a one-off, non-veridical experience. I claim you cannot infer that your present perceptual experience is veridical just on the basis of knowledge of your general reliability. More generally, if you infer that the present F is G, just on the basis of your knowledge that most Fs are Gs, this is what I call statistical inference, and, as I argue, statistical inference by itself does not generate knowledge. I defend this view of statistical inference against objections, including the objection that radical skepticism about our ordinary inductive knowledge will follow unless statistical inference generates knowledge.

In recent years, commentators have begun to re-examine the proximity of Frantz Fanon's and Jacques Lacan's work — a proximity which has traditionally been underappreciated. This article adds to these voices, demonstrating the reciprocal intellectual relationship between these two figures. It develops five interrelated arguments to chart this proximity. First, it emphasizes Lacan's and Fanon's connections through their ontological perspectives on madness. Second, it arbitrates the two theorists’ criticisms of the limits of Western psychoanalysis. Third, it shows the importance placed (...) by both on social structures in determining mental illnesses. Next, it demonstrates the centrality of their common understanding of psychosis. Finally, it argues that Lacan's argument in The Sinthome concerning the colonizer's power is inherited from Fanon's Black Skin, White Masks — itself influenced by Lacan's early theory of language. The article does not attempt to cast Fanon as an apprentice Lacanian but rather to argue that reciprocity helped shape both oeuvres. (shrink)

I develop a new version of the ordinary language response to skepticism. My version is based on premises about the practical functions served by our epistemic words. I end by exploring how my argument against skepticism is interestingly non-circular and philosophically valuable.

Jacques Lacan was a notoriously difficult and idiosyncratic thinker. But is there any value in his hermetically difficult style? By highlighting certain crucial elements of his practice, I show how Lacan enlists the notion of difficulty to press home that he did not want his readers to understand directly. Instead, as Foucault and Althusser explain so well, Lacan wished for his readers and auditors to discover themselves as subjects of desire through reading him. Indeed, in miming the language of the (...) unconscious, Lacan believed he could throw into sharp relief the notion of the unconscious itself and, paradoxically, better express himself. This temporary detour through misunderstanding indicates the programmatic value of difficulty itself. By commenting on the comedic aspect of Lacan's difficult literary dandyism, I also seek to playfully remind the reader that Lacan was a master of comedy and irony and that it is only by adopting a comparative literary approach to his work that we can appreciate how his theory of misunderstanding is at the heart of his conceptualization of madness and psychosis, allowing us to see how, for Lacan, the subject is ontologically sick.

Der Rassimus-Diskurs hat sich auf die fortschrittlichen kapitalistischen Länder konzentriert. Da der Rassimus kein westliches Phänomen ist, sondern eine aus der kapitalistischen Produktionsweise hervorgehende Idologie, sollte die Rassismus-Diskussion auch in Ländern, in denen sich die kapitalistische Produktionsweise erst spät etablierte, untersucht werden. Untersuchungen zu Rassismus in der Türkei zeigen, dass der Rassismus in der Türkei besonderheit aufzeigt, die nicht mit denen der westlichen Länder vergleichbar sind. Deswegen werde ich in meinem Referat den Rassismus in der Türkei vor dem Hintergrund einer (...) Auseinandersetzung mit Albert Memmi, Robert Miles, Immanuel Wallerstein, Etienne Balibar, etc. erlaütern. (shrink)

It can easily look like evolution is in a better position to explain the reliability of our perceptual beliefs than the reliability of our moral beliefs. This paper takes a closer look at the issue and argues that there’s no reason—no reason which armchair philosophers could uncover—to think evolution can better explain perceptual reliability than moral reliability. It also offers a diagnosis of why it seemed otherwise. The diagnosis concerns our need to use the truth predicate as a generalizing logical (...) device in the perceptual case but not in the moral case. (shrink)

If someone disagrees with my moral views, or more generally if I’m in a group of n people who all disagree with each other, but I don’t have any special evidence or basis for my epistemic superiority, then it’s at best a 1-in-n chance that my views are correct. The skeptical threat from disagreement is thus a kind of moral lottery, to adapt a similar metaphor from Sharon Street. Her own genealogical debunking argument, as I discuss, relies on a premise (...) of such disagreement among evolutionary counterparts. -/- In this paper, I resist the threat from disagreement by showing that, on some of the most influential and most attractive theories of content determination, the premise of moral disagreement cannot serve any skeptical or revisionary purposes. I examine and criticize attempts, made by Gilbert Harman and Sharon Street, to argue from disagreement to relativism by relying on a theory of content determination that involves a principle that, within certain constraints, maximizes the attribution to us of true beliefs. And I examine and criticize Robert Williams’s attempt to show there is moral disagreement by relying on a theory of content determination that involves a principle that instead maximizes the attribution to us of rationality. My overall aim is to defend commonsense moral realism via a careful look at the theory of content and concepts. (shrink)

Ehrenmord ist eine nicht selten vorkommende Tat in der Turkei. Mit fortgesetzter Wanderung in die großen Städte der Türkei und ins Ausland, wird dieses Phänomen auch in andere Regionen getragen. Daher setzt sich auch die Öffentlichkeit in zunehmenden Maße mit dieser Thematik auseinander. In diesem Artikel wird versucht, den Ehrenmord unter philosophischen Gesichtspunkten zu erklären.Hierzu werden Gedanken Engels, Butlers, Foucaults, Levi Strauss’ und auch weitere bedeutende Forschungsarbeiten zum Thema Selbstmord hinzugezogen.

Credences are beliefs about evidential probabilities. We give the view an assessment-sensitive formulation, show how it evades the standard objections, and give several arguments in support.

ABSTRACTPopular culture has many examples of evil characters having vertically pupilled eyes. Humans have a long evolutionary history of rivalry with snakes and their visual systems were evolved to rapidly detect snakes and snake-related cues. Considering such evolutionary background, we hypothesised that humans would perceive vertical pupils, which are characteristics of ambush predators including some of the snakes, as threatening. In seven studies conducted on samples from American and Turkish samples, we found that vertical pupils are perceived as more threatening (...) on both explicit and implicit level and they are associated with physical, rather than social, threat. Findings provided partial support regarding our hypothesis about the relevance of snake detection processes: Snake phobia, and not spider phobia, was found to be related to perceiving vertical pupils as threatening, however an experimental manipulation of saliency of snakes re...

Küresel güç mücadelesinde ağırlık merkezinin son yıllarda Asya-Pasifik’e kaymasıyla birlikte, 21. yüzyılın yükselen iki gücü olan Çin Halk Cumhuriyeti (ÇHC) ile Hindistan arasındaki rekabet de önemli ölçüde arttı. Hindistan’ın 1947’de İngiltere’den bağımsızlığını kazanması ile Çin’in Komünist bir Halk Cumhuriyeti olarak 1949’da kurulmasından günümüze dek aralarında süregelen sınır anlaşmazlıkları, iki ülke arasındaki ilişkiyi belirleyen en önemli konuların başında gelmektedir. İki ülkenin de geçmişinde Batı’nın aşağılayıcı müdahalelerine maruz kalmış olmasının yanında bu dönemde uluslararası siyasete hâkim olan iki kutupluluğun dünya barışına hizmet etmeyeceğine (...) olan ortak inançları dünya barışı için alternatif bir oluşum olan Bağlantısızlık Hareketine katılmalarını sağladı. Dolayısıyla bu iki neden ve her iki ülkenin de ulus-devlet oluşumunun erken aşamalarında olması, kuruluşlarının ilk on yılında birbirlerine karşı idealist yaklaşımlar benimsemelerini sağladı. Ancak çok geçmeden her iki ülkenin de materyal kapasitelerini arttırmasıyla birlikte çatışmaya başlayan ulusal çıkarları, Asya idealizminin altını oymaya başladı. Netice itibariyle 1962 gibi erken bir dönemde sıcak çatışmaya girerek Asya idealizmini bir kenara bırakıp ulus devlet realizmini benimsemiş oldular. Bu bağlamda, bu çalışma 21. yüzyılın yükselen iki gücü arasındaki en sorunlu alanlardan biri olan sınır anlaşmazlıklarının süreç içerisindeki evrimini ve bunun iki ülkenin dış politika vizyonlarının değişimleri üzerindeki etkisini ortaya koymaya çalışmaktadır. Bu analizde neoklasik realizm teorik bir çerçeve olarak rehberlik ederken ÇHC ve Hindistan arasındaki sınır sorunlarının yerel, bölgesel ve küresel yönlerini ve bunların iki ülkenin dış politikası üzerindeki etkilerini anlamak için süreç izleme yöntemi kullanılacaktır.

David Lewis (1974, 1994/1999) proposed to reduce the facts about mental representation to facts about sensory evidence, dispositions to act, and rationality. Recently, Robert Williams (2020) and Adam Pautz (2021) have taken up and developed Lewis’s project in sophisticated and novel ways. In this paper, we aim to present, clarify, and ultimately object to the core thesis that they all build their own views around. The different sophisticated developments and defenses notwithstanding, we think the core thesis is vulnerable. We pose (...) a dilemma by considering the two sides of a current epistemological controversy over the relation between evidence and rational belief: permissivism vs. uniqueness. As we argue, the prospects for the Lewisian project look dim when either supposition is clearly made. (shrink)

We debate whether permissivism is true. We start off by assuming an accuracy-oriented framework, and then discuss metaepistemological questions about how our epistemic evaluations promote accuracy.
