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)

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 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)

In this paper I argue that certain type of first-personal causal property, efficacy, is represented in perceptual experience.

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)

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.

In this paper, I argue that certain perceptual relations are represented in visual experience.

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.

In this paper I discuss several proposals for how to find out which contents visual experiences have, and I defend the method I.

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)

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)

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.

Im Folgenden möchte ich einige Thesen zu dem berühmten Brief entwikkeln, den Jacobi im Frühjahr 1799 an Fichte schrieb: Zu dem Brief eines Denkers aus der zweiten Reihe an einen der Grossen des Deutschen Idealismus.

We describe a first experiment on whether product complexity affects competition and consumers in retail markets. We are unable to detect a significant effect of product complexity on prices, except insofar as the demand elasticity for complex products is higher. However, there is qualified evidence that complex products have the potential to induce consumers to buy more than they would otherwise. In this sense, consumer exploitability in quantities cannot be ruled out. We also find evidence for shaping effects: consumers’ preferences (...) are shaped by past experience with prices, and firms may in principle exploit this to sell more. (shrink)

In an experiment on markets for services, we find that consumers are likely to stick to default tariffs and achieve suboptimal outcomes. We find that inattention to the task of choosing a better tariff is likely to be a substantial problem in addition to any task and tariff complexity effect. The institutional setup on which we primarily model our experiment is the UK electricity and gas markets, and our conclusion is that the new measures by the UK regulator Ofgem to (...) improve consumer outcomes are likely to be of limited impact.

It seems obvious that Nietzsche has influenced the Dialectic of Enlightenment (1947). The extent to which Adorno and Horkheimer base their argument on Nietzsche, however, remains controversial. By analyzing an early draft of the first excursion of the Dialectic of Enlightenment from 1943, this article demonstrates that Nietzsche was more important for the development of its main concepts than has been assumed, in particular his analysis of myth and enlightenment. In the earlier version of the Ulysses-chapter Nietzsche, together with Rudolf (...) Borchardt, is a pivotal point of reference. Indeed, it is the Nietzschean reflection on Homer and on the pre-Homerian epic—and Borchardt’s interpretation of these themes—that Adorno views as the first original form of the dialectics of enlightenment.

In this paper I argue that causal relations between objects are represented in visual experience, and contrast my argument and its conclusion with Michotte's results from the 1960's.

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.

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.

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)

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.

Situated in a period that witnessed the genesis of institutions that have lasted to this day, this path-breaking study looks at how ancient Christian women, particularly in Asia Minor and Egypt, initiated ascetic ways of living, and how these practices were then institutionalized. Susanna Elm demonstrates that--in direct contrast to later conceptions--asceticism began primarly as an urban movement, in which women were significant protagonists. In the process, they completely transformed and expanded their roles as wife, mother, or widow: as (...) Christian ascetics, they became `virgin wives', `virgin mothers', and `virgin widows' - with all the legal and economic implications of such a dramatic shift. As importantly, though, Christian men and women ascetics lived together. As `virgins of God' they created new families `in Christ'. No longer determined by their human bonds or human sexuality, they were `neither male nor female'. Finally, the book demonstrates how ascetic bishops - today known as saints - eventually `reformed' these early models of communal, ascetic life by dividing the `virgins of God' into monks and nuns and thus laid the foundation for the monasticism we know today.

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.

This paper develops and defends the capacity view, that is, the view that the ability to perceive the perspective-independent or intrinsic properties of objects depends on the perceiver’s capacity to act. More specifically, I argue that self-location and spatial know-how are jointly necessary to perceive the intrinsic spatial properties of objects. Representing one’s location allows one to abstract from one’s particular vantage point to perceive the perspective-independent properties of objects. Spatial know-how allows one to perceive objects as the kind of (...) things that are perceivable from points of view other than one’s own and thus to perceive them as three-dimensional space occupiers.

A number of Bayesians claim that, if one has no evidence relevant to a proposition P, then one's credence in P should be spread over the interval [0, 1]. Against this, I argue: first, that it is inconsistent with plausible claims about comparative levels of confidence; second, that it precludes inductive learning in certain cases. Two motivations for the view are considered and rejected. A discussion of alternatives leads to the conjecture that there is an in-principle limitation on formal representations (...) of belief: they cannot be both fully accurate and maximally specific. (shrink)

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)

Op-ed about the role of anti-hypocrisy in political criticism.

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.

Reply to John Campbell's contribution to a symposium on *The Contents of Visual Experience*.

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

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.

What is the metaphysical nature of perceptual experience? What evidence does experience provide us with? These questions are typically addressed in isolation. In order to make progress in answering both questions, perceptual experience needs to be studied in an integrated manner. I develop a unified account of the phenomenological and epistemological role of perceptual experience, by arguing that sensory states provide perceptual evidence due to their metaphysical structure. More specifically, I argue that sensory states are individuated by the perceptual capacities (...) employed and that there is an asymmetric dependence between their employment in perception and their employment in hallucination and illusion. Due to this asymmetric dependence, sensory states provide us with evidence. (shrink)

How can perception yield knowledge of the world? One challenge in answering this question is that one necessarily perceives from a particular location. Thus, what is immediately perceptually available is subject to situational features, such as lighting conditions and one’s location. Nonetheless, one can perceive the shape and color of objects. My dissertation aims to provide an explanation for how this is possible. The main thesis is that giving such an explanation requires abandoning the traditional model of perception as a (...) two-place relation between subjects and objects in favor of a model of perception as a three-place relation between subjects, objects, and situations.
