What do we see? We are visually conscious of colors and shapes, but are we also visually conscious of complex properties such as being John Malkovich? In this book, Susanna Siegel develops a framework for understanding the contents of visual experience, and argues that these contents involve all sorts of complex properties. Siegel starts by analyzing the notion of the contents of experience, and by arguing that theorists of all stripes should accept that experiences have contents. She then introduces (...) a method for discovering the contents of experience: the method of phenomenal contrast. This method relies only minimally on introspection, and allows rigorous support for claims about experience. She then applies the method to make the case that we are conscious of many kinds of properties, of all sorts of causal properties, and of many other complex properties. She goes on to use the method to help analyze difficult questions about our consciousness of objects and their role in the contents of experience, and to reconceptualize the distinction between perception and sensation. Siegel's results are important for many areas of philosophy, including the philosophy of mind, epistemology, and the philosophy of science. They are also important for the psychology and cognitive neuroscience of vision. (shrink)

Perception is our key to the world. It plays at least three different roles in our lives. It justifies beliefs and provides us with knowledge of our environment. It brings about conscious mental states. It converts informational input, such as light and sound waves, into representations of invariant features in our environment. Corresponding to these three roles, there are at least three fundamental questions that have motivated the study of perception. How does perception justify beliefs and yield knowledge of our (...) environment? How does perception bring about conscious mental states? How does a perceptual system accomplish the feat of converting varying informational input into mental representations of invariant features in our environment? -/- This book presents a unified account of the phenomenological and epistemological role of perception that is informed by empirical research. So it develops an account of perception that provides an answer to the first two questions, while being sensitive to scientific accounts that address the third question. The key idea is that perception is constituted by employing perceptual capacities - for example the capacity to discriminate instances of red from instances of blue. Perceptual content, consciousness, and evidence are each analyzed in terms of this basic property of perception. Employing perceptual capacities constitutes phenomenal character as well as perceptual content. The primacy of employing perceptual capacities in perception over their derivative employment in hallucination and illusion grounds the epistemic force of perceptual experience. In this way, the book provides a unified account of perceptual content, consciousness, and evidence. (shrink)

Those who model doxastic states with a set of probability functions, rather than a single function, face a pressing challenge: can they provide a plausible decision theory compatible with their view? Adam Elga and others claim that they cannot, and that the set of functions model should be rejected for this reason. This paper aims to answer this challenge. The key insight is that the set of functions model can be seen as an instance of the supervaluationist approach to vagueness (...) more generally. We can then generate our decision theory by applying the general supervaluationist semantics to decision-theoretic claims. The result: if an action is permissible according to all functions in the set, it’s determinately permissible; if impermissible according to all, determinately impermissible; and – crucially – if permissible according to some, but not all, it’s indeterminate whether it’s permissible. This proposal handles with ease some difficult cases ) on which alternative decision theories falter. One reason this view has been overlooked in the literature thus far is that all parties to the debate presuppose that an acceptable decision theory must classify each action as either permissible or impermissible. But I will argue that this thought is misguided. Seeing the set of functions model as an instance of supervaluationism provides a compelling motivation for the claim that there can be indeterminacy in the rationality of some actions. (shrink)

Some prominent evidentialists argue that practical considerations cannot be normative reasons for belief because they can’t be motivating reasons for belief. Existing pragmatist responses turn out to depend on the assumption that it’s possible to believe in the absence of evidence. The evidentialist may deny this, at which point the debate ends in an impasse. I propose a new strategy for the pragmatist. This involves conceding that belief in the absence of evidence is impossible. We then argue that evidence can (...) play a role in bringing about belief without being a motivating reason for belief, thereby leaving room for practical considerations to serve as motivating reasons. I present two ways in which this can happen. First, agents can use evidence as a mere means by which to believe, with practical considerations serving as motivating reasons for belief, just as we use tools (e.g. a brake pedal) as mere means by which to do something (e.g. slow down) which we are motivated to do for practical reasons. Second, evidence can make it possible for one to choose whether or not to believe – a choice one can then make for practical reasons. These arguments push the debate between the evidentialist and the pragmatist into new territory. It is no longer enough for an evidentialist to insist that belief is impossible without evidence. Even if this is right, the outcome of the debate remains unsettled. It will hang on the ability of the evidentialist to respond to the new pragmatist strategy presented here. (shrink)

There are powerful reasons to think of perceptual content as determined at least in part by the environment of the perceiving subject. Externalist views such as this are often rejected on grounds that they do not give a good account of hallucinations. The chapter shows that this reason for rejecting content externalism is not well founded if we embrace a moderate externalism about content, that is, an externalist view on which content is only in part dependent on the experiencing subject“s (...) environment. The chapter starts by motivating content externalism. It then argues that hallucinations are best understood in terms of a deficiency of veridical perceptual experiences. The chapter discusses the consequences of this thesis by developing a view of hallucinations that is committed to externalism about content. (shrink)

This paper proposes that the question “What should I believe?” is to be answered in the same way as the question “What should I do?,” a view I call Equal Treatment. After clarifying the relevant sense of “should,” I point out advantages that Equal Treatment has over both simple and subtle evidentialist alternatives, including versions that distinguish what one should believe from what one should get oneself to believe. I then discuss views on which there is a distinctively epistemic sense (...) of should. Next I reply to an objection which alleges that non-evidential considerations cannot serve as reasons for which one believes. I then situate Equal Treatment in a broader theoretical framework, discussing connections to rationality, justification, knowledge, and theoretical vs. practical reasoning. Finally, I show how Equal Treatment has important implications for a wide variety of issues, including the status of religious belief, philosophical skepticism, racial profiling and gender stereotyping, and certain issues in psychology, such as depressive realism and positive illusions.

Includes a summary of my book *The Rationality of Perception* (Oxford, 2017) and replies to commentaries on it by Endre Begby, Harmen Ghijsen, and Katia Samoilova. These commentaries and my summary and replies will be published soon in Analysis Reviews. Begby focuses on my analysis of the epistemic features of the interface between individual minds and their cultural milieu (discussed in chapter 10 of *The Rationality of Perception*), Ghijsen focuses on the notion of inference and reliabilism (chapters 5 and 6), (...) and Samoilova focuses on the relationship between epistemic charge (chapter 3) and shifts in the amount of justification needed for knowledge.

In this paper I argue that it's possible that the contents of some visual experiences are influenced by the subject's prior beliefs, hopes, suspicions, desires, fears or other mental states, and that this possibility places constraints on the theory of perceptual justification that 'dogmatism' or 'phenomenal conservativism' cannot respect.

Literary historians have been working productively in recent years to reclaim the texture of early-fifteenth-century English poetry in contexts of politics and religion. To the list of major authors we should add John Audelay, chaplain of Knockin , setting him equally beside his contemporaries Thomas Hoccleve, John Lydgate, and Margery Kempe. As a vernacular poet with a name, a provenance, and a rich body of work, Audelay warrants serious regard. His oeuvre displays an artistry that is different from, but as (...) innovative and revelatory of his times as, those of his celebrated contemporaries. (shrink)

Women and men respond differently to mock news stories about new developments in science and technology, with women associating more risk and less benefit than do men with reported developments overall. Interview data were used to construct a survey instrument designed to probe for differences in underlying attitudes that might explain this outcome. Results from administration of the questionnaire reveal that women are more likely than men to agree with "antiscience" statements. The assertion that women and men can be thought (...) of as members of distinct cultures is invoked to provide a theoretical explanation for the data. (shrink)

German philosophy as it is today can best disprove the various theories of "Historical Reason." Philosophic thought seems to go its necessary way regardless of immediate historical and social situations.

In this paper, I describe and criticize M.G.F. Martin's version of disjunctivism, and his argument for it from premises about self-knowledge.

Perception grounds demonstrative reference, yields singular thoughts, and fixes the reference of singular terms. Moreover, perception provides us with knowledge of particulars in our environment and justifies singular thoughts about particulars. How does perception play these cognitive and epistemic roles in our lives? I address this question by exploring the fundamental nature of perceptual experience. I argue that perceptual states are constituted by particulars and discuss epistemic, ontological, psychologistic, and semantic approaches to account for perceptual particularity.

Recently, the thesis that experience is fundamentally a matter of representing the world as being a certain way has been questioned by austere relationalists. I defend this thesis by developing a view of perceptual content that avoids their objections. I will argue that on a relational understanding of perceptual content, the fundamental insights of austere relationalism do not compete with perceptual experience being representational. As it will show that most objections to the thesis that experience has content apply only to (...) accounts of perceptual content on which perceptual relations to the world play no explanatory role. With austere relationalists, I will argue that perceptual experience is fundamentally relational. But against austere relationalists, I will argue that it is fundamentally both relational and representational. (shrink)

This paper defends a principle I call Equal Treatment, according to which the rationality of a belief is determined in precisely the same way as the rationality of any other state. For example, if wearing a raincoat is rational just in case doing so maximizes expected value, then believing some proposition P is rational just in case doing so maximizes expected value. This contrasts with the popular view that the rationality of belief is determined by evidential support. It also contrasts (...) with the common idea that in the case of belief, there are two different incommensurable senses of rationality, one of which is distinctively epistemic. I present considerations that favor Equal Treatment over these two alternatives, reply to objections, and criticize some arguments for Evidentialism. I also show how Equal Treatment opens the door to a distinctive kind of response to skepticism. (shrink)

There is an important division in the human mind between perception and reasoning. We reason from information that we have already, but perception is a means of taking in new information. Susanna Siegel argues that these two aspects of the mind become deeply intertwined when beliefs, fears, desires, or prejudice influence what we perceive.

Early formulations of disjunctivism about perception refused to give any positive account of the nature of hallucination, beyond the uncontroversial fact that they can in some sense seem to the same to the subject as veridical perceptions. Recently, some disjunctivists have attempt to account for hallucination in purely epistemic terms, by developing detailed account of what it is for a hallucinaton to be indiscriminable from a veridical perception. In this paper I argue that the prospects for purely epistemic treatments of (...) hallucinations are dim, and that this undermines the case for disjunctivism. (shrink)

This paper develops a criterion for sameness of Fregean senses. I consider three criteria: logical equivalence, intensional isomorphism, and epistemic equipollence. I reject the first two and argue for a version of the third.

I argue that perceptual consciousness is constituted by a mental activity. The mental activity in question is the activity of employing perceptual capacities, such as discriminatory, selective capacities. This is a radical view, but I hope to make it plausible. In arguing for this mental activist view, I reject orthodox views on which perceptual consciousness is analyzed in terms of peculiar entities, such as, phenomenal properties, external mind-independent properties, propositions, sense-data, qualia, or intentional objects.

The first full philological edition in English of the Roman philosopher Seneca's De Clementia. It includes the Latin text with apparatus criticus, a new English translation, a substantial introduction, and a commentary on matters of textual and literary criticism and issues of socio-political, historical, cultural, and philosophical significance.

In this paper I offer a theory of what makes certain influences on visual experiences by prior mental states (including desires, beliefs, moods, and fears) reduce the justificatory force of those experiences. The main idea is that experiences, like beliefs, can have rationally assessable etiologies, and when those etiologies are irrational, the experiences are epistemically downgraded.

An overview of the epistemology of perception, covering the nature of justification, immediate justification, the relationship between the metaphysics of perceptual experience and its rational role, the rational role of attention, and cognitive penetrability. The published version will contain a smaller bibliography, due to space constraints in the volume.

In discussions of perception and its relation to knowledge, it is common to distinguish what one comes to believe on the basis of perception from the distinctively perceptual basis of one's belief. The distinction can be drawn in terms of propositional contents: there are the contents that a perceiver comes to believe on the basis of her perception, on the one hand; and there are the contents properly attributed to perception itself, on the other. Consider the content.

Vigilantism, commonly glossed as “taking the law into one’s own hands,” has been analyzed differently in studies of comparative politics, ethnography, history, and legal theory, but has attracted little attention from philosophers. What can “taking the law into one’s hands” amount to? How does vigilantism relate to mobs, protests, and self-defense? I distinguish between several categories of vigilantism, identify the questions they are most useful for addressing, and offer an analysis on which vigilantism is a kind of political initiative done (...) for the sake of enacting an immediate realignment of power in a polity in accordance with a political vision. In addition to defining a special kind of political initiative, my analysis helps us understand a range of rhetorical powers related to vigilantism, including some of the ways that attributions of vigilantism can mask instances of self-defense, and attributions of self-defense can mask instances of vigilantism.

I argue that perception is necessarily situation-dependent. The way an object is must not just be distinguished from the way it appears and the way it is represented, but also from the way it is presented given the situational features. First, I argue that the way an object is presented is best understood in terms of external, mind-independent, but situation-dependent properties of objects. Situation-dependent properties are exclusively sensitive to and ontologically dependent on the intrinsic properties of objects, such as their (...) shape, size, and color, and the situational features, such as the lighting conditions and the perceiver’s location in relation to the perceived object. Second, I argue that perceiving intrinsic properties is epistemically dependent on representing situation-dependent properties. Recognizing situation-dependent properties yields four advantages. It makes it possible to embrace the motivations that lead to phenomenalism and indirect realism by recognizing that objects are presented a certain way, while holding on to the intuition that subjects directly perceive objects. Second, it acknowledges that perceptions are not just individuated by the objects they are of, but by the ways those objects are presented given the situational features. Third, it allows for a way to accommodate the fact that there is a wide range of viewing conditions or situational features that can count as normal. Finally, it makes it possible to distinguish perception and thought about the same object with regard to what is represented. (shrink)

Evidentialists and Pragmatists about reasons for belief have long been in dialectical stalemate. However, recent times have seen a new wave of Evidentialists who claim to provide arguments for their view which should be persuasive even to someone initially inclined toward Pragmatism. This paper reveals a central flaw in this New Evidentialist project: their arguments rely on overly demanding necessary conditions for a consideration to count as a genuine reason. In particular, their conditions rule out the possibility of pragmatic reasons (...) for action. Since the existence of genuine pragmatic reasons for action is common ground between the Evidentialist and the Pragmatist, this problem for the New Evidentialist arguments is fatal. The upshot is that the deadlock between these two positions is restored: neither side can claim to be in possession of an argument that could convince the other. As it happens, I myself favor Pragmatism about reasons for belief, and although I don't claim to be able to convince a committed Evidentialist, I do make a prima facie case for Pragmatism by describing particular scenarios in which it seems to be true. I then go on to develop my own preferred version of the view: Robust Pragmatism, according to which a consideration never constitutes a reason for believing a proposition purely in virtue of being evidence for it.

This book breaks new ground in our understanding of how we perceive and represent the space around us - one of the central topics in cognitive psychology. It presents a new view of development and spatial cognition by reversing the usual focus on vision and examining the evidence on representation in the total absence of vision without specific brain damage. Findings from the author's work with congenitally totally blind and with sighted children, together with studies from a wide variety of (...) other areas, are set in the context of intersensory and spatial development. Touch and movement are considered as converging sources of reference information with and without vision. The findings have important implications for future work in many fields, particularly developmental pscychology; cognition, cognitive neuroscience and visual handicap, and make this new work essential reading for students and researchers in these fields.

I argue that inference can tolerate forms of self-ignorance and that these cases of inference undermine canonical models of inference on which inferrers have to appreciate (or purport to appreciate) the support provided by the premises for the conclusion. I propose an alternative model of inference that belongs to a family of rational responses in which the subject cannot pinpoint exactly what she is responding to or why, where this kind of self-ignorance does nothing to undermine the intelligence of the (...) response.

Siegel and Byrne debate whether perceptual experiences present rich properties or exclusively thin properties.

This paper defends the Content View: the thesis that all visual experiences have contents.

This is a review of the book Archiving Sovereignty by Stewart Motha. Typical of critical legal writing, the monograph challenges our conditioned perception about the sovereign State. As such, it provides us with access to an archive of sovereign violence created by the law. It is argued that judicial decisions sustain and recreate sovereign power by way of destruction of facts. The focus here is on states with imperial histories, taking as case studies several islands in the Indian ocean region.

My concerns are about the phrase “the nature of imagery,” and the interpretation of findings with blind people. This discussion considers reports of imagery by congenitally totally blind people, and what should not be inferred from comparing efficiency levels of blind and sighted people in spatial tasks.

This book analyses the role of diagrammatic reasoning in Plato’s philosophy: the readers will realize that Plato, describing the stages of human cognitive development using a diagram, poses a logic problem to stimulate the general reasoning abilities of his readers. Following the examination of mental models in this book, the readers will reflect on what inferences can be useful to approach this kind of logic problem. Plato calls for a collaboration between writer and readers. In this book the readers will (...) examine the connection between diagrams and discovery, realizing the important epistemic role of visualization. They will recognize the crucial role that diagrams play in problem solving. The logic problem elaborated by Plato is addressed considering the epistemic function of mental models. These models introduce to an advanced stage of cognitive development, in which reasoning uses in its investigations a higher-level of mathematical complexity, represented by structuralism. (shrink)

In this work, Professors Rosenfeld and Mancini have brought together an impressive group of authors to provide a comprehensive analysis on the greater demand for religions exemptions to government mandates. Traditional religious conscientious objection cases, such as refusal to salute the flag or to serve in the military during war, had a diffused effect throughout society. In sharp contrast, these authors argue that today's most notorious objections impinge on the rights of others, targeting practices like abortion, LGTBQ adoption, and same-sex (...) marriage. The dramatic expansion of conscientious objection claims have revolutionized the battle between religious traditionalists and secular civil libertarians, raising novel political, legal, constitutional and philosophical challenges. Highlighting the intersection between conscientious objections, religious liberty, and the equality of women and sexual minorities, this volume showcases this political debate and the principal jurisprudence from different parts of the world and emphasizes the little known international social movements that compete globally to alter the debate's terms.

The introduction of social distancing, as part of efforts to try and curb the spread of the COVID-19 pandemic, has brought about drastic disruption to the world of the performing arts. In the UK the majority of professional orchestral musicians are freelance and therefore self-employed. These players, previously engaged in enjoyable, busy, successful, portfolio careers, are currently unable to earn a living carrying out their everyday work of performing music, and their future working lives are surrounded by great uncertainty. The (...) aim of the present study was to examine how established professional musicians are experiencing this period, and to look for similarities and differences between the experiences of musicians in the middle of their performing careers, with those of older players. Single semi-structured interviews were carried out over Zoom with 24 freelance, self-employed orchestral musicians; 12 mid-career musicians aged 35–45, and 12 seasoned musicians aged 53 and over. Thematic analysis identified themes common to both groups: the loss of a much-loved performing career, missing music making and colleagues, and anxiety about the future of the music profession. It also identified differences between the two groups: challenges to their identity as a musician, the extent of their anxiety about finances, the extent of their emotional distress, attitudes toward practicing and engaging in collaborative music making, and confusion over future career plans. Findings are discussed with reference to lifespan models of musicians' career development, the PERMA model of wellbeing, and the concept of resilience. (shrink)

I argue that there are phenomenological constraints on what it is to see an object, and that these are overlooked by some theories that offer allegedly sufficient causal and counterfactual conditions on object-seeing.
