Charles Travis promotes a conception of knowledge on which knowledge is unmistakable. I raise some issues about what he means by this. Though sympathetic to his project, I give reasons for doubting that he has shown that all knowledge depends on having proof.

It is well-known that naïve realism has difficulty accommodating perceptual error. Recent discussion of the issue has focused on whether the naïve realist can accommodate hallucination by adopting disjunctivism. However, illusions are more difficult for the naïve realist to explain precisely because the disjunctivist solution is not available. I discuss what I take to be the two most plausible accounts of illusion available to the naïve realist. The first claims that illusions are cases in which you are prevented from perceiving (...) properties you would ordinarily perceive and subsequently form a mistaken judgment about the perceived object. The second appeals to an unusual look or appearance that the perceived object instantiates. I argue that neither account is satisfactory and that, consequently, naïve realism ought to be rejected.

An explanation is given of why it is in the nature of inquiry into whether or not p that its aim is fully achieved only if one comes to know that p or to know that not-p and, further, comes to know how one knows, either way. In the absence of the latter one is in no position to take the inquiry to be successfully completed or to vouch for the truth of the matter in hand. An upshot is that (...) although knowledge matters because truth matters this should not be understood to mean that knowledge matters because true belief matters. (shrink)

Alan Millar examines our understanding of why people think and act as they do. His key theme is that normative considerations form an indispensable part of the explanatory framework which we use to understand each other. Millar offers illuminating discussions of reasons for belief and reasons for action, the explanation of beliefs and actions in terms of the subject's reasons, the idea that simulation has a key role in understanding people, and the limits of explanation in terms of (...) propositional attitudes.

Philosophical research into olfaction often focuses on its limitations. We explore instead an underappreciated capacity of the sense of smell, namely, its role in interpersonal experience. To illustrate this, we examine how smell can enable continuing connections to deceased loved ones. Understanding this phenomenon requires an appreciation of, first, how olfaction's limitations can facilitate experiences of the deceased person and, second, how olfaction enables experiences of what we refer to as the ‘olfactory air’ of a person. This way of experiencing (...) someone privileges their status as an environmentally situated human animal. (shrink)

Empirical research provides striking examples of non-human animal responses to death, which look very much like manifestations of grief. However, recent philosophical work appears to challenge the idea that animals can grieve. Grief, in contrast to more rudimentary emotional experiences, has been taken to require potentially human-exclusive abilities like a fine-grained sense of particularity, an ability to project toward the distal future and the past, and an understanding of death or loss. This paper argues that these features do not rule (...) out animal grief and are present in many animal loss responses. It argues that the principal kind of “understanding” involved in grief is not intellectual but is instead of a practical variety available to animals, and outlines ways that the disruption to an animal’s life following a loss can hinge upon a specific individual and involve a degree of temporal organisation.

A conception of recognitional abilities and perceptual-discriminative abilities is deployed to make sense of how perceptual experiences enable us to make cognitive contact with objects and facts. It is argued that accepting the emerging view does not commit us to thinking that perceptual experiences are essentially relational, as they are conceived to be in disjunctivist theories. The discussion explores some implications for the theory of knowledge in general and, in particular, for the issue of how we can shed light on (...) the nature of knowledge is if we do not aim to provide conceptual analyses of knowledge in terms of true belief plus something else. Consideration is also given how we can best make sense of the practical value that knowledge has for us. (shrink)

Plausibly perceptual knowledge satisfies the following: It is knowledge about things from the way they appear. It can embrace more than the way things appear. It is phenomenologically immediate and thus, in one sense, non-inferential. and place a significant constraint on adequate elucidations of . Knowledge about an object, from the way it looks, which embraces more than the way it looks, should not turn out to be inferential in the relevant sense. The paper shows how this constraint can be (...) met, drawing upon a conception of a discriminative capacity. The discussion touches on literature dealing with observation in science, knowledge of other minds, and the possibility of moral knowledge. (shrink)

This article outlines a conception of perceptual-recognitional abilities. These include abilities to recognize certain things from their appearance to some sensory modality, as being of some kind, or as possessing some property. An assumption of the article is that these abilities are crucial for an adequate understanding of perceptual knowledge. The specific aim here is to contrast those abilities with abilities or competences as conceived in the virtue-theoretic literature, with particular reference to views of Ernest Sosa and John Greco. In (...) the course of the discussion, it is emphasized that the notion of exercising a perceptual-recognitional ability is a success notion: exercising such an ability is nothing less than acquiring knowledge. Even so, the view can make sense of our fallibility. It can also be defended in the face of an objection stemming from consideration of what are here called success-rate abilities. (shrink)

Alan Miller offers a focused account of perceptual knowledge, the knowledge that we gain by means of seeing, hearing, feeling, smelling, and tasting. He explains perceptual knowledge in terms of general recognitional abilities, then situates that account within a broader perspective on epistemology and philosophical method more generally.

In Sense and Content , Christopher Peacocke points out that two equally-sized trees at different distances from the perceiver are normally represented to be the same size, despite the fact that in a certain sense the nearer tree looks bigger ; he concludes on the basis of this observation that visual experiences possess irreducibly phenomenal properties. This argument has received the most attention of all of Peacocke’s arguments for separatism—the view that the intentional and phenomenal properties of experiences are independent (...) of one another. However, despite its notoriety, the argument is widely misunderstood and underappreciated. I argue that once the structure of the argument is clarified and the replies that have been offered are considered closely, one must conclude that the trees argument is successful. (shrink)

Objects are central to perception and our interactions with the world. We perceive the world as parsed into discrete entities that instantiate particular properties, and these items capture our attention and shape how we interact with the environment. Recently there has been some debate about whether the sense of smell allows us to perceive odours as discrete objects, with some suggesting that olfaction is aspatial and doesn’t allow for object-individuation. This paper offers two empirically tractable criteria for assessing whether particular (...) objects are exhibited in perceptual experience— susceptibility to figure-ground segregation and perceptual constancies—and argues that these criteria are fulfilled by olfactory perception, and thus there are olfactory objects. I argue that there are, in fact, two different ways that olfaction allows for figure-ground segregation. First, I look at various Gestalt grouping principles, which are thought to govern when features are perceived as grouped into structured wholes, segregated from everything around them. I argue that these principles apply to olfactory experience, providing evidence of non-spatial figure-ground segregation. Second, I defend the contentious idea that a spatial variety of figure-ground segregation can also occur in olfaction. To see this, however, we need to look to empirical evidence showing that tactile stimulation and bodily movements play a crucial role in olfactory phenomenology. Finally, I draw on empirical evidence and olfactory phenomenology to argue that there are perceptual constancies in olfactory experience, allowing us to perceive odours as coherent objects that survive shifts in our perspectives on the world.

There is a traditional conception of sensory experience on which the experiences one has looking at, say, a cat could be had by someone merely hallucinating a cat. Disjunctivists take issue with this conception on the grounds that it does not enable us to understand how perceptual knowledge is possible. In particular, they think, it does not explain how it can be that experiences gained in perception enable us to be in ‘cognitive contact’ with objects and facts. I develop this (...) chal- lenge to the traditional conception and then show that it is possible to accommo- date an adequate account of cognitive contact in keeping with the traditional conception. One upshot of the discussion is that experiences do not bear the explanatory burden placed upon them by disjunctivists. (shrink)

A number of EU institutions and government committees across Europe have expressed interest in developing methods and decision-support tools to facilitate consideration of the ethical dimensions of biotechnology assessment. As part of the work conducted in the EC supported project on ethical tools (Ethical Bio-TA Tools), a number of ethical frameworks with the potential to support the work of public policy decision-makers has been characterized and evaluated. One of these potential tools is the Delphi method. The Delphi method was originally (...) developed to assess variables that are intangible and/or shrouded in uncertainty by drawing on the knowledge and abilities of a diverse group of experts through a form of anonymous and iterative consultation. The method has hitherto been used by a diversity of practitioners to explore issues such as technology assessment, environmental planning, and public health measures. From the original (classical) Delphi, a family of Delphi-related processes has emerged. As a result of the evaluation of the various Delphi processes, it is proposed that the classical method can be further developed and applied as a form of ethical framework to assist policy-makers. Through a series of exercises and trials, an Ethical Delphi has been developed as a potential approach for characterizing ethical issues raised by the use of novel biotechnologies. Advantages and disadvantages of the method are discussed. Further work is needed to develop the procedural aspects of the Ethical Delphi method and to test its use in different cultural contexts. However, utilizing an ethical framework of this type combines the advantages of a methodical approach to capture ethical aspects with the democratic virtues of transparency and openness to criticism. Ethical frameworks such as the Ethical Delphi should contribute to better understanding of and decision-making on issues that involve decisive ethical dimensions. (shrink)

There are countless occasions when we find people’s thought or action intelligible, or anticipate what they will think or do, or are at least unsurprised by what they think or do, despite our having little if any information about their attitudes other than what we can gather from their situation and non-verbal behaviour. This article explores the role of practices, conceived as essentially rule-governed activities, is making this possible. Consideration is given to practicies for the use of words.

When you have a perceptual experience of a given physical object that object seems to be immediately present to you in a way it never does when you consciously think about or imagine it. Many philosophers have claimed that naïve realism (the view that to perceive is to stand in a primitive relation of acquaintance to the world) can provide a satisfying account of this phenomenological directness of perceptual experience while the content view (the view that to perceive is to (...) represent the world to be a certain way) cannot. I argue that this claim is false. Specifically, I maintain that the only acceptable naïve realist account of the relevant phenomenology is circular and that the content view can provide a similar account. In addition, I maintain that a certain specific variety of the content view provides a non-circular and thus more satisfactory account of this phenomenology. If so, then contrary to what is commonly assumed there are powerful phenomenological grounds for preferring the content view to naïve realism. (shrink)

It is argued that seeing that P is a mode of knowing that P that is to be explained in terms of the exercise of visual-perceptual recognitional abilities. The nature of those abilities is described. The justification for believing that P, when one sees that P, is provided by the fact that one sees that P. Access to this fact is explained in terms of an ability to recognize of seen objects that one is seeing them. Reasons for resistance to (...) such an account are considered. The distinction between merely reasonable belief and well-founded belief is emphasised. (shrink)

Recent epistemology has reflected a growing interest in issues about the value of knowledge and the values informing epistemic appraisal. Is knowledge more valuable that merely true belief or even justified true belief? Is truth the central value informing epistemic appraisal or do other values enter the picture? Epistemic Value is a collection of previously unpublished articles on such issues by leading philosophers in the field. It will stimulate discussion of the nature of knowledge and of directions that might be (...) taken by the theory of knowledge.

A perceptual experience of a given object seems to make the object itself present to the perceiver’s mind. Many philosophers have claimed that naïve realism (the view that to perceive is to stand in a primitive relation of acquaintance to the world) provides a better account of this phenomenological directness of perceptual experience than does the content view (the view that to perceive is to represent the world to be a certain way). But the naïve realist account of this phenomenology (...) has a conspicuous shortcoming: it explains the phenomenological directness of veridical perceptual experiences but not of hallucinations. Conversely, I maintain that a particular variety of the content view provides a unified account of the phenomenological directness of both veridical and hallucinatory experiences. If so, then contrary to what is often assumed, the phenomenological facts concerning perceptual experience are explained better by the content view than by naïve realism, and consequently, we have a compelling reason to prefer the content view to naïve realism.

Millar argues against the tendency in current philosophical thought to treat sensory experiences as a peculiar species of propositional attitude. While allowing that experiences may in some sense bear propositional content, he presents a view of sensory experiences as a species of psychological state. A key theme in his general approach is that justified belief results from the competent exercise of conceptual capacities, some of which involve an ability to respond appropriately to current experience. In working out this approach (...) the author develops a view of concepts and their mastery, explores the role of groundless beliefs drawing on suggestions of Wittgenstein, illuminates aspects of the thought of Locke, Hume, Quine, and Goldman, and finally offers a response to a sophisticated variety of scepticism.

The philosophy of grief has directed little attention to bereavement’s impact on perceptual experience. However, misperceptions, hallucinations and other anomalous experiences are strikingly common following the death of a loved one. Such experiences range from misperceiving a stranger to be the deceased, to phantom sights, sounds and smells, to nebulous quasi-sensory experiences of the loved one’s presence. This paper draws upon the enactive sensorimotor theory of perception to offer a phenomenologically sensitive and empirically informed account of these experiences. It argues (...) that they can be understood as deriving from disruption to both sensorimotor expectations and perceived opportunities for action, stemming from the upheaval of bereavement. Different facets of the enactive sensorimotor approach can help to explain different types of post-bereavement perceptual experience. Post-bereavement misperceptions can be accounted for through the way that alterations to sensorimotor expectations can result in atypical ‘amodal completion’, while bereavement hallucinations can be understood as ‘appearances’ that fail to form part of the usual patterns of sensorimotor contingency. Quasi-sensory experiences of the presence of the deceased can be understood as resulting from changes to perceived affordances. This paper aims to demonstrate the explanatory value of key aspects of the sensorimotor approach by highlighting how they can help to explain the phenomenology of post-bereavement experiences. However, it also illuminates certain areas in which the sensorimotor approach ought to be supplemented, especially if it is to account for tight connections between perception, affect, and intersubjectivity that are salient in grief.

A conception of the relation between reasons for belief, justified belief, and knowledge is outlined on which a belief is justified, in the sense of being well‐founded, only if there is an adequate reason to believe it, reasons to believe something are constituted by truths, and a reason to believe something justifies one in believing it only if it is constituted by a truth or truths that one knows. It is argued that, contrary to initial appearances, perceptual justification does not (...) pose a problem for this view. The discussion touches upon the relation between believing for reasons and reflective knowledge. (shrink)

The widely accepted “continuing bonds” model of grief tells us that rather than bereavement necessitating the cessation of one’s relationship with the deceased, very often the relationship continues instead in an adapted form. However, this framework appears to conflict with philosophical approaches that treat reciprocity or mutuality of some form as central to loving relationships. Seemingly the dead cannot be active participants, rendering it puzzling how we should understand claims about continued relationships with them. In this article, we resolve this (...) tension by highlighting two fundamental aspects of paradigmatic loving relationships that can, and often do, continue in an adapted form following bereavement: love and mutual shaping of interests, choices, and self-concepts. Attention to these continuing features of relationships helps to capture and clarify the phenomenological and behavioral features of continuing bonds. However, love and mutual shaping must also change in important ways following bereavement. Love becomes unreciprocated, and although the dead continue to shape our interests, choices, and self-concepts, we predominantly shape their legacies and memories in return. These changes place important constraints upon the nature of our interpersonal connections with the dead. (shrink)

How we understand the nature and role of grief depends on what we take its object to be and vice versa. This paper focuses on recent claims by philosophers that grief is frequently or even inherently irrational or inappropriate in one or another respect, all of which hinge on assumptions concerning the proper object of grief. By emphasizing the temporally extended structure of grief, we offer an alternative account of its object that undermines these assumptions and dissolves the apparent problems. (...) The principal object of grief, we suggest, is a loss of life possibilities, which is experienced, understood, and engaged with over a prolonged period. Other descriptions of grief's object identify more specific aspects of this loss in ways that do not respect a straightforward distinction between concrete and formal objects. (shrink)

It is widely acknowledged that individual moral obligations and responsibility entail shared (or joint) moral obligations and responsibility. However, whether individual epistemic obligations and responsibility entail shared epistemic obligations and responsibility is rarely discussed. Instead, most discussions of doxastic responsibility focus on individuals considered in isolation. In contrast to this standard approach, I maintain that focusing exclusively on individuals in isolation leads to a profoundly incomplete picture of what we're epistemically obligated to do and when we deserve epistemic blame. First, (...) I argue that we have epistemic obligations to perform actions of the sort that can be performed in conjunction with other people, and that consequently, we are often jointly blameworthy when we violate shared epistemic obligations. Second, I argue that shared responsibility is especially important to doxastic responsibility thanks to the fact that we don't have the same kind of direct control over our beliefs that we have over our actions. In particular, I argue that there are many cases in which a particular individual who holds some problematic belief only deserves epistemic blame in virtue of belonging to a group all the members of which are jointly blameworthy for violating some shared epistemic obligation.

The mechanistic model depicts scientific explanations as involving the discovery of multi-level, organized components that constitute a target phenomenon. Meanwhile, sensorimotor enactivism purports to offer a scientifically informed account of perceptual experience as a skill-laden interactive relationship, constitutively involving both perceiver and world, rather than as an agent-bound representation of the world. Insofar as sensorimotor enactivism identifies an empirically tractable phenomenon – skillful agent-world interaction – and mechanistic explanation establishes the subpersonal components of this phenomenon, the two approaches allow for (...) a fruitful division of labor in investigating perceptual experience. On closer inspection, however, two challenges arise. First, the “representation challenge” arises because promising attempts to set out implementational details of our sensorimotor interaction with the world implicate cognitive representations, creating tension with sensorimotor enactivism’s nonrepresentational commitments. Second, the “reconstitution challenge” arises when mechanistic explanation not only uncovers the components of some established phenomenon but plays a role in “reconstituting” this phenomenon. This means that, through investigating mechanisms, perceptual experience may be reconceived such that its constituents are wholly organism-bound. We explore both challenges to the compatibility of mechanism and sensorimotor enactivism and examine possible solutions. The result is a clearer understanding of the tensions and opportunities for learning between the frameworks. (shrink)

© Millar 2018This bold, provocative, and highly original book is in three Parts. Part I outlines a problem, sketches a solution, and defends a claim that is crucial to the solution—that ‘perceptual experiences and the processes by which they arise can be rational or irrational’. This claim is The Rationality of Perception. In Part II Siegel argues that the power of experiences to justify beliefs can be downgraded or upgraded by psychological precursors. Part III applies, and further develops, the (...) theoretical framework that has been outlined in the previous parts. The topics addressed there include fearful and wishful seeing, and selection effects as they bear on the character of experiences. The last chapter concerns the appraisal of culturally appropriated racial attitudes that can influence beliefs and, on Siegel’s view, visual experiences as well. The discussion throughout takes readers well off the beaten track and is to... (shrink)

Rowlands defends environmentalism, that is, the conjunction of the ontological claim that cognitive processes are not located exclusively inside the skin of cognizing organisms and the epistemological claim that it is not possible to understand the nature of cognitive processes by focusing exclusively on what is occurring inside the skin of cognizing organisms. Chapter 3 is devoted to explaining how environmentalism differs from other forms of externalism about the mental. The crucial points are that the arguments to be presented for (...) the ontological claim do not turn on considerations about the content of mental states, that environmentalism implies a strong form of externalism, and that standard arguments for externalism, based on considerations about content, do not establish the strong form.

The consensus in contemporary philosophy of mind is that how a perceptual experience represents the world to be is built into its sensory phenomenology. I defend an opposing view which I call ‘moderate separatism’, that an experience's sensory phenomenology does not determine how it represents the world to be. I argue for moderate separatism by pointing to two ordinary experiences which instantiate the same sensory phenomenology but differ with regard to their intentional content. Two experiences of an object reflected in (...) a mirror can possess the same spatial phenomenology while representing that object to occupy different spatial locations. So, contrary to the current consensus, the representation of spatial location is not fixed by an experience's sensory phenomenology. (shrink)
