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.

I offer an explanation of how subjects are able to perceive the intrinsic spatial properties of objects, given that subjects always perceive from a particular location. The argument proceeds in two steps. First, I argue that a conception of space is necessary to perceive the intrinsic spatial properties of objects. This conception of space is spelled out by showing that perceiving intrinsic properties requires perceiving objects as the kind of things that are perceivable from other locations. Second, I show that (...) having such a conception of space presupposes that a subject represent her location in relation to perceived objects. More precisely the thesis is that a subject represents her location as the location from which she both perceives objects and would act in relation to objects were she to act. So I argue that perception depends on the capacity to know what it would be to act in relation to objects. (shrink)

In The Problem of Perception, A.D. Smith’s central aim is to defend the view that we can directly perceive ordinary objects, such as cups, keys and the like.1 The book is organized around the two arguments that Smith considers to be serious threats to the possibility of direct perception: the argument from illusion, and the argument from hallucination. The argument from illusion threatens this possibility because it concludes that indirect realism is true. Indirect realism is the view that we perceive (...) mind-independent ordinary objects, but can only do so indirectly, by perceiving mind-dependent objects: objects whose existence depends on being perceived or thought about. The argument from hallucination draws a similar conclusion: if we perceive mindindependent ordinary objects at all, then our perception of them is indirect in the same way. In responding to these arguments, Smith develops an account of percep- tual consciousness. Perceptual consciousness is a kind of experience, distinct from what Smith calls ‘mere sensory experiences’, or equivalently, ‘mere sensation’. Perceptual consciousness is experience that is properly percep- tual, in which one has the phenomenology of perceiving things in the external world (including one’s body) that exist independently of one’s mind. Perceptual consciousness on its own does not suffice for actually being in perceptual contact with mind-independent reality, although it suffices for it to seem as if one i s . It follows that perceptual consciousness does not suffice for direct perception of ordinary objects, or for direct realism. Nevertheless, Smith holds that the correct account of perceptual consciousness is a crucial element in blocking the arguments from illusion and hallucination, and therefore in supporting the possibility of direct perception. This is an extraordinarily engaging book. Within a single, unified narrative, one encounters the views of many philosophers—Husserl, Fine, Broad, Sextus Empiricus, Loar, Schopenhauer, Meinong, Burge, Dilthey, Russell, Dennett, Sartre, O’Shaughnessy, Evans, Berkeley, Craig, Brentano and many....

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

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)

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.

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)

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)

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)

My replies to Errol Lord, Adam Pautz, and Peter Railton's commentaries on The Rationality of Perception (2017).

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.

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 part one I present a positive argument for the claim that philosophical argument can rationally overturn common sense. It is widely agreed that science can overturn common sense. But every scientific argument, I argue, relies on philosophical assumptions. If the scientific argument succeeds, then its philosophical assumptions must be more worthy of belief than the common sense proposition under attack. But this means there could be a philosophical argument against common sense, each of whose premises is just as worthy (...) of belief as the scientist’s philosophical assumptions. If so, then the purely philosophical argument will also succeed. In part two I consider three motivations, each of which comprises a distinct philosophical methodology, for the opposing view: the Moorean idea that common sense enjoys greater plausibility than philosophy; case judgments should trump general principles; reflective equilibrium and conservatism. I argue that all three motivations fail. (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)

Critical discussion of Andromache has almost invariably focused on the question of unity. As everyone who has ever read a critical account of the play knows, the action falls into three parts: the plot against Andromache by Hermione and her father, foiled by Peleus; Hermione's subsequent panicky flight with Orestes; and Neoptolemos' murder at Orestes' instigation. The play appears not to possess ‘unity of action’ in the strict Aristotelian sense: there is, for instance, no tight causal connection between the plot (...) against Andromache and Orestes' plot against Neoptolemos. Troubled by this, critics have made a variety of attempts to find unity of another sort: unity of ‘theme’. Each has asked, ‘What is Andromache about?’, taking the question in an absolute sense; and has assumed that one must search for a single answer. (shrink)

One kind of substantial critique which has been raised by several philosophers against the so called higher order perception theory , advocated for mainly by William Lycan, concerns the combination of two important claims: that qualia are wide contents of perceptual experiences, and that the subject becomes aware of what the world is like by perceiving her own experiences of the world. In what sense could we possibly watch our own mental states if they are representations whose content and qualitative (...) character is determined by factors that are external to the mind? And, furthermore, how can we become aware of what the world is like by means of this process? Fred Dretske says that all we could become aware of by this alleged activity are activities of the nervous system. But being aware of what e.g., a certain colour is like to us, does not seem to be the same as being aware of what a particular nervous activation pattern is like to us. Barry Maund points out that it is not ruled out that the representational vehicle and the representational object share some properties, nor that it is in virtue of having certain properties that a mental state has the content it does. If it were the case that the properties of the representational states showed some iconic resemblance relation to that which they represent, there could perhaps be some point in watching them. But again, we have little reason for thinking that this is the case. It seems improbable that an experience of red would be red, i.e., that the representational vehicle would have these properties. The important issue is: what features could the representational vehicle possibly have that would make it suitable as an object for inner sense and, in turn, would enable us to become aware of what it is like for us to perceive external objects by “looking” at the representation of these objects? I will explore these questions in this paper. (shrink)

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.

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)

This is the Stanford Encyclopedia of Philosophy entry on the contents of perception.

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 perceptual relations are represented in visual experience.

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 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.

I argue that any account of perceptual experience should satisfy the following two desiderata. First, it should account for the particularity of perceptual experience, that is, it should account for the mind-independent object of an experience making a difference to individuating the experience. Second, it should explain the possibility that perceptual relations to distinct environments could yield subjectively indistinguishable experiences. Relational views of perceptual experience can easily satisfy the first but not the second desideratum. Representational views can easily satisfy the (...) second but not the first desideratum. I argue that to satisfy both desiderata perceptual experience is best conceived of as fundamentally both relational and representational. I develop a view of perceptual experience that synthesizes the virtues of relationalism and representationalism, by arguing that perceptual content is constituted by potentially gappy de re modes of presentation.

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.

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

I analyze a type of practice related to inquiry: treating things as zetetically relevant to questions, and argue that this practice is a central normatively evaluable way to extend lines of inquiry. My strategy is to introduce the practice and its normative features by examining its relationship to something already well-understood: the ways that news stories produced by journalists frame events. I then argue that the same core zetetic practice can be found across domains, just not in journalism. Finding the (...) same practice across such different human settings suggests it is a core feature of inquiry. (shrink)

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.

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.

I develop a view of the common factor between subjectively indistinguishable perceptions and hallucinations that avoids analyzing experiences as involving awareness relations to abstract entities, sense-data, or any other peculiar entities. The main thesis is that hallucinating subjects employ concepts (or analogous nonconceptual structures), namely the very same concepts that in a subjectively indistinguishable perception are employed as a consequence of being related to external, mind-independent objects or property-instances. These concepts and nonconceptual structures are identified with modes of presentation types. (...) Since a hallucinating subject is not related to any such objects or property-instances, the concepts she employs remain empty. I argue that the phenomenology of hallucinations and perceptions can be identified with employing concepts and analogous nonconceptual structures. By doing so, I defend an ontologically minimalist view of the phenomenology of experience that (1) vindicates Aristotelianism about types and (2) amounts to a naturalized view of the phenomenology of experience.

UN peace operations have increasingly focused on the importance of “local ownership.” The logic is simple. For peace operations to succeed in helping war-torn states to create accountable, democratic institutions grounded in the rule of law, peace operations need to internalize democratic principles by making UN missions accountable to different domestic constituencies—crossing ethnic, religious, racial, social, and gender lines—within the war-torn country. As part of a special issue on “The United Nations at Seventy-Five: Looking Back to Look Forward,” this essay (...) argues that while there is widespread consensus among UN member states and UN bureaucrats that local ownership is necessary, UN peace operations have faced significant obstacles to creating true local ownership. These obstacles include the UN's focus on host-government ownership; the challenge of creating trust with different domestic constituencies that represent diverse perspectives; the supply-driven nature of UN intervention; and the mismatch between the UN's ideal post-conflict state and the preferences of post-conflict societies. To make UN peace operations more responsive to post-conflict societies, UN staff often have to bend or break rules established only to hold them accountable to their member states. (shrink)

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.

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)
