The Müller-Lyer illusion is the natural consequence of the construction of the vertebrate eye, retina and visual processing system. Due to imperfections in the vertebrate eye and retina and due to the subsequent processing in the system by ever increasing receptive fields, the visual information becomes less and less precise with respect to exact location and size. The consequence of this is that eventually the brain has to calculate a weighted mean value of the information, which is spread out over (...) a population of neurons. In the case of the Müller-Lyer illusion this inevitably leads to extension of one and reduction of the other line. The arguments presented explain several published experimental results concerning the Müller-Lyer illusion and shed new light upon the philosophical neutrality of observation sentences. (shrink)

Müller provides a valuable synthesis of neurobiological evidence on the epigenetic development of neural structures involved in language acquisition. The pluripotentiality of developing neural tissue crucially constrains linguistic/cognitive theorizing about supposedly innate neural mechanisms and contributes significantly to our understanding of experience–dependent processes involved in language acquisition. Without this understanding, any proposed explanation of language acquisition is suspect.

Why engage in inquiry? According to many philosophers, the goal of inquiring into some question is to come to know its answer. While this view holds considerable appeal, this paper argues that it stands in tension with another highly attractive thesis: knowledge does not require absolute certainty. Forced to choose between these two theses, I argue that we should reject the idea that inquiry aims at knowledge. I go on to develop an alternative view, according to which inquiry aims at (...) maximizing the epistemic value of our credences. This alternative view makes room for knowledge that falls shy of certainty, and it coheres nicely with a rich body of work in epistemic decision theory. I proceed to highlight the implications of this replacement for some important topics in epistemology, including the dogmatism paradox, the nature of interrogative attitudes, and the norm of practical reasoning.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The New Husserl: A Critical ReaderBob SandmeyerDonn Welton, editor. The New Husserl: A Critical Reader. Bloomington: Indiana University Press, 2003. Pp. xxv + 334. Cloth, $75.00. Paper, $29.95.Donn Welton has put together a superb collection of twelve essays which "provide an alternative to the standard approach to Husserl by examining his method as a whole and by offering depth-probes into a number of issues, old and new, that (...) occupied [Husserl] during his exceptionally productive later period" (xi). Although classed under five subheadings by Welton, the essays are of three types generally. These are (1) essays which provide introduction to and overview of Husserl's philosophy, especially as expressed in his later works, (2) essays of comparison between aspects of Husserl's philosophy and other non-phenomenological or psychological theories, and (3) analytic essays which treat a particular thematic within (and transcending) Husserl's phenomenological philosophy.The book begins with Klaus Held's wonderfully coherent introductions to Husserl's phenomenological method and phenomenology of the life-world. Although these two essays are not new, they remain original and current overviews of Husserl's whole philosophy [End Page 122] translated into English for the first time. More importantly, they do not lapse into an obtuse jargon so typical of Husserlian scholarship. Both essays provide an excellent introduction to the major themes of Husserl's philosophy.Three essays within the collection are primarily comparative. Dieter Lohmar delves into a notoriously thorny issue within Kant's first critique, i.e., the schematism of concepts, in order to compare this against Husserl's concept of type. But he attempts herein to articulate something that "never really interested Kant" (97), i.e., the empirical genesis of the schemata. Apart from providing a clear account of the genesis of empirical schema within Kantian philosophy, Lohmar also clarifies the Husserlian conception of type as instituted in perceptual consciousness. Rudolf Bernet examines the appearing of Unconsciousness as presented by Freud in order to "show how it is possible that consciousness can bring to present appearance something unconscious... without thereby incorporating it into or subordinating it to the conscious present" (200). Bernet achieves two ends in this fine essay. He employs Husserl's theory of phantasy in inner-time consciousness in order to intimate a solution to the seeming aporia implicit in Freud's theory of unconscious consciousness. More importantly to Husserlian scholarship, however, Bernet also provides a fine articulation of Husserl's theory of phantasy as it develops from the "apprehension of a content of apprehension" schema to that of a non-positing, intuitive-reproductive presentification. Donn Welton's essay, "World as Horizon," attacks the semantic theory of claims and descriptions espoused primarily by Robert Brandom. What is lacking in Brandom's theory of claims and, by extension, in any abstracting semantic theory, Welton argues, is the proper starting point. Speech acts must be understood from within a theory of world "as a nexus of significance that situates not only our multiple discourses about different regions but also the regions themselves" (224).The bulk of the essays in this collection, however, are analytic in nature and range over themes as diverse as intentionality, inner-time-consciousness, self-reflection, intersubjectivity and the differing styles of phenomenological analysis within Husserl's philosophy. Perhaps the best essays in this collection, given its aim, are Lanei Rodemeyer's essay "Developments in the Theory of Time-Consciousness: an Analysis of Protention" and Anthony Steinbock's "Generativity and the Scope of Generative Phenomenology." Where Rodemeyer concentrates her attention on explicating the role of protention in all of Husserl's time-analyses—but most especially in the later Bernauer and C manuscripts, Steinbock looks from within Husserl's philosophy to a style of analysis that goes beyond Husserl to become "a communal effort, not just among contemporary phenomenologists, but as a project handed down and appropriated over the generations" (317 ff.). With the exception of David Carr's essay on subjectivity in the transcendental tradition, what is common to all these analytical essays is the dominant place of Husserl's late analyses of inner-time-consciousness and temporalization. These analyses play a major role in the two essays just... (shrink)

In this collection of closely interrelated essays, Robert Young emphasizes the scope of the nineteenth-century debate on 'man's place in nature' at the same time as he engages with the approaches of scholars who write about it. He is critical of the separation of the writing of history from writing about history, historiography, and of the separation of history from politics and ideology, then or now. Dr Young challenges fellow historians for reimposing the very disciplinary boundaries that the nineteenth-century debate (...) showed were in the service of ideological forces in that culture. Rather, he proposes that the full weight of the contending forces should be made apparent and debated openly so that neither nineteenth-century nor contemporary issues about the role of science in culture should be treated in a narrow perspective.

This paper argues that we should assign certainty a central place in epistemology. While epistemic certainty played an important role in the history of epistemology, recent epistemology has tended to dismiss certainty as an unattainable ideal, focusing its attention on knowledge instead. I argue that this is a mistake. Attending to certainty attributions in the wild suggests that much of our everyday knowledge qualifies, in appropriate contexts, as certain. After developing a semantics for certainty ascriptions, I put certainty to explanatory (...) work. Specifically, I argue that by taking certainty as our central epistemic notion, we can shed light on a variety of important topics, including evidence and evidential probability, epistemic modals, and the normative constraints on credence and assertion.

In the future, when we compare the welfare of a being of one substrate (say, a human) with the welfare of another (say, an artificial intelligence system), we will be making an intersubstrate welfare comparison. In this paper, we argue that intersubstrate welfare comparisons are important, difficult, and potentially tractable. The world might soon contain a vast number of sentient or otherwise significant beings of different substrates, and moral agents will need to be able to compare their welfare levels. However, (...) this work will be difficult, because we lack the same kinds of commonalities across substrates that we have within them. Fortunately, we might be able to make at least some intersubstrate welfare comparisons responsibly in spite of these issues. We make the case for cautious optimism and call for more research.

The past decade has seen a protracted debate over the semantics of epistemic modals. According to contextualists, epistemic modals quantify over the possibilities compatible with some contextually determined group’s information. Relativists often object that contextualism fails to do justice to the way we assess utterances containing epistemic modals for truth or falsity. However, recent empirical work seems to cast doubt on the relativist’s claim, suggesting that ordinary speakers’ judgments about epistemic modals are more closely in line with contextualism than relativism (...) (Knobe & Yalcin 2014; Khoo 2015). This paper furthers the debate by reporting new empirical research revealing a previously overlooked dimension of speakers’ truth-value judgments concerning epistemic modals. Our results show that these judgments vary systematically with the question under discussion in the conversational context in which the utterance is being assessed. We argue that this ‘QUD effect’ is difficult to explain if contextualism is true, but is readily explained by a suitably flexible form of relativism. (shrink)

Pacifists and their opponents disagree not only about moral questions, but rather often about factual questions as well—as seen when looking at the controversy surrounding the crisis in Kosovo. According to my reconstruction of pacifism, this is not surprising since the pacifist,legitimately, looks at the facts in the light of her system of value. Her opponent, in turn, looks at the facts in the light of an alternative value system, and the quarrel between the two parties about supposedly descriptive matters (...) never ceases, as there is no objective reality about the war in question that could settle the issue.In my view, the pacifist's value-laden way of looking at reality implicitly obeys three epistemic imperatives. First, the Epistemic Imperative concerning Human Nature ("Resist demonizing the other side; always try to understand the case from the other point of view"). Second, the Epistemic Imperative concerning Non-Violent Alternatives ("Always search for non-violent alternatives to military action"). Third, the Epistemic Imperative concerning Uncontrolled Escalation ("Hone your senses to the uncontrolled, irreversible side effects of military action, particularly to the danger of military escalation leading to another world war"). Objective reality has no way of telling us how far we should go in following these imperatives. Rather, we have to make the decision about how far we are going to take them ourselves. In this way, the pacifist's epistemic imperatives are comparable to Kant's regulative principles. (shrink)

One leading approach to justification comes from the reliabilist tradition, which maintains that a belief is justified provided that it is reliably formed. Another comes from the ‘Reasons First’ tradition, which claims that a belief is justified provided that it is based on reasons that support it. These two approaches are typically developed in isolation from each other; this essay motivates and defends a synthesis. On the view proposed here, justification is understood in terms of an agent’s reasons for belief, (...) which are in turn analyzed along reliabilist lines: an agent's reasons for belief are the states that serve as inputs to their reliable processes. I show that this synthesis allows each tradition to profit from the other's explanatory resources. In particular, it enables reliabilists to explain epistemic defeat without abandoning their naturalistic ambitions. I go on to compare my proposed synthesis with other hybrid versions of reliabilism that have been proposed in the literature. (shrink)

There are many introductions to the animal ethics literature. There aren't many introductions to the practice of doing animal ethics. Bob Fischer's Animal Ethics: A Contemporary Introduction fills that gap, offering an accessible model of how animal ethics can be done today. The book takes up classic issues, such as the ethics of eating meat and experimenting on animals, but tackles them in an empirically informed and nuanced way. It also covers a range of relatively neglected issues in animal ethics, (...) such as the possibility of insect sentience and the ethics of dealing with pests. Finally, the book doesn't assess every current practice using standard ethical theories, but tries to evaluate some of them using the moral frameworks endorsed by those involved. So, for instance, there is a chapter on the way that animal care and use committees try to justify some of the educational uses of animals, and the chapter on zoos considers the way that international zoological societies justify compromising animal welfare. The book wraps up with a discussion of the future of animal ethics. Each chapter opens with a helpful initial overview of the chapter and ends with a list of suggested readings to help students go further on their own. Key Features Covers animal ethics from an empirically informed perspective, bringing philosophy into conversation with key issues in animal science, conservation biology, economics, ethology, and legal studies, among other fields Provides ample coverage of the most salient current topics, including, for example: Debates about which animals are sentient The suffering of wild animals Research ethics The boundaries of activism Avoids suggesting that animal ethics is simply the practice of applying the right general theory to a problem, instead allowing readers to first work out the specific costs and benefits of making ethical decisions Impresses upon the reader the need for her to work out for herself the best way forward with difficult ethical issues, suggesting that progress can indeed be made Includes summaries and recommended readings at the end of each chapter.

Relativism and expressivism offer two different semantic frameworks for grappling with a similar cluster of issues. What is the difference between these two frameworks? Should they be viewed as rivals? If so, how should we choose between them? This chapter sheds light on these questions. After providing an overview of relativism and expressivism, I discuss three potential choice points: their relation to truth conditional semantics, their pictures of belief and communication, and their explanations of disagreement.

Considered by many to be Abraham Robinson's magnum opus, this book offers an explanation of the development and applications of non-standard analysis by the mathematician who founded the subject. Non-standard analysis grew out of Robinson's attempt to resolve the contradictions posed by infinitesimals within calculus. He introduced this new subject in a seminar at Princeton in 1960, and it remains as controversial today as it was then. This paperback reprint of the 1974 revised edition is indispensable reading for anyone interested (...) in non-standard analysis. It treats in rich detail many areas of application, including topology, functions of a real variable, functions of a complex variable, and normed linear spaces, together with problems of boundary layer flow of viscous fluids and rederivations of Saint-Venant's hypothesis concerning the distribution of stresses in an elastic body.

Here, Bob Hale and Crispin Wright assemble the key writings that lead to their distinctive neo-Fregean approach to the philosophy of mathematics. In addition to fourteen previously published papers, the volume features a new paper on the Julius Caesar problem; a substantial new introduction mapping out the program and the contributions made to it by the various papers; a section explaining which issues most require further attention; and bibliographies of references and further useful sources. It will be recognized as the (...) most powerful presentation yet of a neo-Fregean program. (shrink)

One attractive feature of process reliabilism is its reductive potential: it promises to explain justification in entirely non-epistemic terms. In this paper, I argue that the phenomenon of epistemic defeat poses a serious challenge for process reliabilism’s reductive ambitions. The standard process reliabilist analysis of defeat is the ‘Alternative Reliable Process Account’ (ARP). According to ARP, whether S’s belief is defeated depends on whether S has certain reliable processes available to her which, if they had been used, would have resulted (...) in S not holding the belief in question. Unfortunately, ARP proves untenable. I show, by way of counterexample, that ARP fails to articulate either necessary or sufficient conditions on defeat. Process reliabilists must either provide an alternative reductive account of defeat or renounce their reductive aspirations. (shrink)

Nach Morton White können wir die holistische Quine/Duhem-These auf ethische Sätze genauso anwenden wie auf wissenschaftliche. Demzufolge mögen sich die meisten ethische Sätze zwar nicht einzeln testen lassen, wohl aber im Zusammenhang einer kompletten Theorie, die sowohl deskriptive als auch normative Sätze enthält. Ich diskutiere zwei Vorschläge dafür, wie dieser Vergleich durchbuchstabiert werden könnte. Laut Whites eigenem Vorschlag lassen sich einige normative Konsequenzen des Gesamtsystems durch Konfrontation mit den emotionalen Reaktionen des Sprechers testen. Laut meinem Vorschlag sind einige normative Konsequenzen (...) des Systems bereits Beobachtungssätze in Quines Sinn und können genauso getestet werden wie naturwissenschaftliche Beobachtungssätze, nämlich durch Sinneserfahrung. Kurzum, es gibt moralische Beobachtungssätze. Quine bezeichnet diejenigen Sätze als Beobachtungssätze, die alle anwesenden Sprecher einer Gemeinschaft stets gleich beurteilen und die der einzelne Sprecher ausschließlich aufgrund momentaner Sinnesreizung bejaht oder verneint (also unabhängig von Hintergrund-Informationen). In Quines Argument gegen moralische Beobachtungssätze steckt folgender Fehler: Quine glaubt, dass sich moralische Fragen immer nur angesichts von Hintergrund-Informationen beurteilen lassen. Bei vielen moralischen Sätzen mag das so sein; aber es gibt Gegenbeispiele, in denen Hintergrund-Informationen ausgeschaltet sind, z.B. "Dies ist sichtbares Unrecht". (shrink)

According to many philosophers, belief is a settling state. On this view, someone who believes p is disposed to take p for granted in practical and theoretical reasoning. This paper presents a simple objection to this settling conception of belief: it conflicts with our ordinary patterns of belief ascription. I show that ascriptions of unsettled beliefs are commonplace, and that they pose problems for all of the most promising ways of developing the settling conception. I proceed to explore the implications (...) of my argument for the relation between belief and credence, and for the relative importance of belief in psychological explanation. (shrink)

We know that animals are harmed in plant production. Unfortunately, though, we know very little about the scale of the problem. This matters for two reasons. First, we can’t decide how many resources to devote to the problem without a better sense of its scope. Second, this information shortage throws a wrench in arguments for veganism, since it’s always possible that a diet that contains animal products is complicit in fewer deaths than a diet that avoids them. In this paper, (...) then, we have two aims: first, we want to collect and analyze all the available information about animal death associated with plant agriculture; second, we try to show just how difficult it’s to come up with a plausible estimate of how many animals are killed by plant agriculture, and not just because of a lack of empirical information. Additionally, we show that there are significant philosophical questions associated with interpreting the available data—questions such that different answers generate dramatically different estimates of the scope of the problem. Finally, we document current trends in plant agriculture that cause little or no collateral harm to animals, trends which suggest that field animal deaths are a historically contingent problem that in future may be reduced or eliminated altogether.

As we begin our exploration of our relationship with animals, we come face to face with Peter Singer and his insistence that speciesism is a vice. It is important to come to know what he means by speciesism, why he regards it as a moral mistake.

De nos jours, les partis politiques et les syndicats communiquent avant tout de jour, afin de se faire entendre du plus grand nombre. Il n’en a pas toujours été ainsi. En pleine Guerre froide, les militants devaient bien souvent agir la nuit pour promouvoir et défendre leurs idées – quitte à s’exposer physiquement à des représailles de leurs adversaires. La communication politique après-guerre privilégiait bien souvent les meetings nocturnes (non-)contradictoires, parfois émaillés d’incidents. Ce n’est que progressivement avec la technicisation de (...) la communication et la mise à distance des corps que la violence physique va reculer pour perdurer dans les marges politiques. Profondément liés à des organisations politiques, les syndicats répondaient en partie au même schéma, bien que le déclin de la violence physique nocturne se soit enclenché plus rapidement au profit d’une violence diurne maîtrisée.

This paper develops a new challenge for moral noncognitivism. In brief, the challenge is this: Beliefs — both moral and non-moral — are epistemically evaluable, whereas desires are not. It is tempting to explain this difference in terms of differences in the functional roles of beliefs and desires. However, this explanation stands in tension with noncognitivism, which maintains that moral beliefs have a desire-like functional role. After critically reviewing some initial responses to the challenge, I suggest a solution, which involves (...) rethinking the functional relationship between desire and belief. (shrink)

Bob Hale presents a broadly Fregean approach to metaphysics, according to which ontology and modality are mutually dependent upon one another. He argues that facts about what kinds of things exist depend on facts about what is possible. Modal facts are fundamental, and have their basis in the essences of things--not in meanings or concepts.
