Early modern empiricists thought that the nature of perceptual experience is given by citing the object presented to the mind in that experience. Hallucination and illusion suggest that this requires untenable mind-dependent objects. Current orthodoxy replaces the appeal to direct objects with the claim that perceptual experience is characterized instead by its representational content. This paper argues that the move to content is problematic, and reclaims the early modern empiricist insight as perfectly consistent, even in cases of illusion, with the (...) realist contention that these direct objects of perception are the persisting mind-independent physical objects we all know and love.

Bill Brewer presents an original view of the role of conscious experience in the acquisition of empirical knowledge. He argues that perceptual experiences must provide reasons for empirical beliefs if there are to be any determinate beliefs at all about particular objects in the world. This fresh approach to epistemology turns away from the search for necessary and sufficient conditions for knowledge and works instead from a theory of understanding in a particular area.

What is the role of conscious experience in the epistemology of perceptual knowledge: how should we characterise what is going on in seeing that o is F in order to illuminate the contribution of seeing o to their status as cases of knowing that o is F? My proposal is that seeing o involves conscious acquaintance with o itself, the concrete worldly source of the truth that o is F, in a way that may make it evident to the subject (...) that o is an instance of ‘x is F’ as she understands this, and hence evident that o is F. Seeing that o is F is thus a way of its being evident that o is F and is therefore a way of knowing that o is F. (shrink)

It is close to current orthodoxy that perceptual experience is to be characterized, at least in part, by its representational content, roughly, by the way it represents things as being in the world around the perceiver. Call this basic idea the content view.

I take it for granted that sense experiential states provide reasons for empirical beliefs; indeed this claim forms the first premise of my central argument for (CC). 1 The subsequent stages of the argument are intended to establish that a person has such a reason for believing something about the way things are in the world around him only if he is in some mental state or other with a conceptual content: a conceptual state. Thus, given that sense experiential states (...) do provide reasons for empirical beliefs, they must have conceptual content. (shrink)

Over the past ten years, we have worked in a collaboration between educators and computer scientists at the University of Illinois to imagine futures for education in the context of what is loosely called “artificial intelligence.” Unhappy with the first generation of digital learning environments, our agenda has been to design alternatives and research their implementation. Our starting point has been to ask, what is the nature of machine intelligence, and what are its limits and potentials in education? This paper (...) offers some tentative answers, first conceptually, and then practically in an overview of the results of a number of experimental implementations documented in greater detail elsewhere. Our key finding is that artificial intelligence—in the context of the practices of electronic computing developing over the past three quarters of a century—will never in any sense “take over” the role of teacher, because how it works and what it does are so profoundly different from human intelligence. However, within the limits that we describe in this paper, it offers the potential to transform education in ways that—counterintuitively perhaps—make education more human, not less. (shrink)

A timely new edition of the classic journalism guide, now featuring updated material on the importance of reporting in the age of media mistrust and fake news--and how journalists can use technology while also navigating its challenges. More than two decades ago, the Committee of Concerned Journalists gathered some of America's most influential newspeople to ask the question "What is journalism for?" Through exhaustive research, surveys, interviews, and public forums, they identified the essential elements that define journalism and its role (...) in our society. The result is one of the most important books on the media ever written, winner of the Goldsmith Book Prize from Harvard, the Society of Professional Journalists Award, and the Bart Richards Award from Penn State University. Updated with new material covering the ways journalists can deftly leverage technology to their advantage, especially given the shifting revenue architecture--with "clickbait" fading away and consumers paying a higher premium for quality reporting--this fourth edition of The Elements of Journalism is an essential read for journalists, students, and anybody hoping to stay informed in contentious times.

Physical objects are such things as stones, tables, trees, people and other animals: the persisting macroscopic constituents of the world we live in. therefore expresses a commonsense commitment to physical realism: the persisting macroscopic constituents of the world we live in exist, and are as they are, quite independently of anyone.

The question how to account for illusion has had a prominent role in shaping theories of perception throughout the history of philosophy. Prevailing philosophical wisdom today has it that phenomena of illusion force us to choose between the following two options. First, reject altogether the early modern empiricist idea that the core subjective character of perceptual experience is to be given simply by citing the object presented in that experience. Instead we must characterize perceptual experience entirely in terms of its (...) representational content. Second, retain the early modern idea that the core subjective character of experience is simply constituted by the identity of its direct objects, but admit that these must be mind-dependent entities, distinct from the mind-independent physical objects we all know and love. I argue here that the early modern empiricists had an indispensable insight. The idea that the core subjective character of perceptual experience is to be given simply by citing the object presented in that experience is more fundamental than any appeal to perceptual content, and can account for illusion, and indeed hallucination, without resorting to the problematic postulation of any such mind-dependent objects.

In The Varieties of Reference (1982), Gareth Evans claims that considerations having to do with certain basic ways we have of gaining knowledge of our own physical states and properties provide "the most powerful antidote to a Cartesian conception of the self" (220). In this chapter, I start with a discussion and evaluation of Evans' own argument, which is, I think, in the end unconvincing. Then I raise the possibility of a more direct application of similar considerations in defence of (...) common sense anti-Cartesianism. Progress in this direction depends upon a far more psychologically informed understanding of normal and abnormal bodily awareness than is generally found in philosophical discussions of these issues. In the context of my attempt at some such understanding, I go on to assess the potential of this more direct line of argument. (shrink)

On an act utilitarian view it is morally permissible if not obligatory to choose to perform an action which contributes as much as any other action to the total happiness of all those capable of enjoying happiness. As the view has just been stated, however, there is some question of how we are to understand the phrase “all those capable of enjoying happiness”. For even leaving aside the possibility that animals or spirits might be included, there is still the matter (...) of the size of the population of humans “capable of enjoying happiness”. Furthermore, among our ethical decisions themselves are decisions which would cause a decrease or increase in population and which in perhaps even more specific ways determine the applicability of this phrase “all those capable of enjoying happiness”. According to the socalled classical or total utilitarian principle, the phrase in question is understood as describing some population whose existence will enable one to maximize the net amount of happiness. For on the classical principle what one is obligated to do is simply to maximize net happiness. (shrink)

We perceive a world of mind-independent macroscopic material objects such as stones, tables, trees, and animals. Our experience is the joint upshot of the way these things are and our route through them, along with the various relevant circumstances of perception; and it depends on the normal operation of our perceptual systems. How should we characterise our perceptual experience so as to respect its basis and explain its role in grounding empirical thought and knowledge? I offered an answer to this (...) question in Perception and its objects. Here I aim to clarify some of my central arguments and to develop and defend the position further in the light of subsequent critical discussion. (shrink)

The standard paradigm for mental causation is a person’s acting for a reason. Something happens - she intentionally φ’s - the occurrence of which we explain by citing a relevant belief or desire. In the present context, I simply take for granted the following two conditions on the appropriateness of this explanation. First, the agent φ’s _because_ she believes/desires what we say she does, where this is expressive of a _causal_ dependence.1 Second, her believing/desiring this gives her a _reason_ for (...) φ-ing: recognizing that she has this belief/desire makes her φ-ing intelligible as rational in the light of her other attitudes and circumstances. A further condition must be met, though, if this is to be a genuine psychological explanation, a case of her acting _for_ the reason in question. Consider the following example of Davidson’s (1973, p. 79). An exhausted climber is desperate to rid herself of the weight and danger of holding her partner on a rope; and her sudden realization that simply letting go would achieve this so unnerves her that her grip loosens slightly and he falls. Her releasing him causally depends upon her having this belief and desire, which provide _a_ reason for doing what she does. But this is not _why_ she does it: it would be at best misleading to say that she dropped him, intentionally, because she was fed up with holding his weight, or because she thought that she might otherwise fall. Her letting go does not depend upon her having these reasons in the right way. The reason-giving relation is causally irrelevant. If we are to explain a person’s acting _for_ a reason, then her doing. (shrink)

Allen, B., Arithmetizing Uniform NC, Annals of Pure and Applied Logic 53 1–50. We give a characterization of the complexity class Uniform NC as an algebra of functions on the natural numbers which is the closure of several basic functions under composition and a schema of recursion. We then define a fragment of bounded arithmetic, and, using our characterization of Uniform NC, show that this fragment is capable of proving the totality of all of the functions in Uniform NC. Lastly, (...) in the spirit of Buss, we show that any function which is definable by a ∑b1-formula in our theory is a function which is in Uniform NC. (shrink)

In this paper I discuss a number of different relationships between two kinds of obligation: those which have individuals as their subject, and those which have groups of individuals as their subject. I use the name collective obligations to refer to obligations of the second sort. I argue that there are collective obligations, in this sense; that such obligations can give rise to and explain obligations which fall on individuals; that because of these facts collective obligations are not simply reducible (...) to individual obligations; and that collective obligations supervene on individual obligations, without being reducible to them. The sort of supervenience I have in mind here is what is sometimes called ‘global supervenience’. In other words, there cannot be two worlds which differ in respect of the collective obligations which exist in them without also differing in respect of the individual obligations which exist in them.

From time to time we explain what people do by referring to their habits. We explain somebody’s putting the kettle on in the morning as done through “force of habit”. We explain somebody’s missing a turning by saying that she carried straight on “out of habit”. And we explain somebody’s biting her nails as a manifestation of “a bad habit”. These are all examples of what will be referred to here as habit explanations. Roughly speaking, they explain by referring to (...) a pattern of a particular kind of behaviour which is regularly performed in characteristic circumstances, and has become automatic for that agent due to this repetition.

Traditional ecocentric ethics relies on an ecology that emphasizes the stability and integrity of ecosystems. Numerous ecologists now focus on natural systems that are less clearly characterized by these properties. We use the elimination and restoration of wolves in Yellowstone to illustrate troubles for traditional ecocentric ethics caused by ecological models emphasizing instability in natural systems. We identify several other problems for a stability-integrity based ecocentrism as well. We show how an ecocentric ethic can avoid these difficulties by emphasizing the (...) value of the wildness of natural systems and we defend wildness value from a rising tide of criticisms. (shrink)

Recent literature portrays caring as a psychological, social, and ethical orientation associated with female gender identity. This essay focuses on Giliigan's influential view that “care” is a broad theme of moral development which is under-represented in dominant theories of human development such as Kohlberg's theory. An alternative hypothesis is proposed portraying care development as a set of circumscribed coping strategies tailored to dealingwith sexism. While these strategies are practically effective and partially “liberated,” from the moral point of view, they also (...) reflect the debilitating influences of sexist socialization even at the highest level. Gilligan and her colleagues seem to misidentify these inadequacies of mature care. This alternative hypothesis is briefly related to the critical and feminist tradition. Then it is supported with Gilligan's own research and interpretive text. (shrink)

In his comments, Richard Fumerton carefully develops two fundamental concerns with my views, which he interprets sympathetically, and almost entirely correctly. Before turning to these concerns, though, I must make one point about his concise opening statement of my principal claims. As I hope is clear from my précis, perceptual experiences provide reasons for empirical beliefs not simply in virtue of sharing demonstrative content with them. The key idea is that a person cannot properly grasp the objective content of these (...) experiences—that is, he cannot actually have experiences of particular things in the mind-independent world around him—without understanding that his apprehension that things are thus and so out there is in part due to the fact that they are. He therefore recognizes the relevant content as his epistemic openness to the way things objectively are. This is clearly central to my overall position. (shrink)

Realism concerning a given domain of things is the view that the things in that domain exist, and are as they are, quite independently of anyone.

We perceive things in the external world as spatially located both with respect to each other and to ourselves, such that they are in principle accessible from where we seem to be. I hear the door bang behind me; I feel the pen on the desk over to my right; and I see you walking beneath the line of pictures, from left to right in front of me. By displaying these spatial relations between its objects and us, the perceivers, perception (...) places us in the perceived world: our world and the world we perceive are one. Clearly this is not achieved by our continually perceiving ourselves along with the things around us, and thus recovering our position with respect to them. Indeed I shall argue that there are serious difficulties with the suggestion that this might be the basic mechanism for perceptual self- location. Furthermore, I shall argue that our existence as an element of the objective order cannot be inferred from the raw given in sense perception. Hence it cannot even be on the right lines as an answer to the question 'What is it for perception to represent its objects as environmental to the subject?', that it should present these objects, along with the perceiving subject himself, or along with something from which his existence in the perceived world could be deduced, in the very same frame so to speak. Nevertheless it yields him an awareness of himself as there in the wings of that scene, genuinely located with respect to the action, yet somehow not normally quite getting onto the stage. And I shall argue here, that perceptual contents succeed in being self-locating in this way in.. (shrink)

Much of the current imaging literature either denies the existence of wakeful non-mental imagers, views non-imagers motivationally as 'repressors' or 'neurotic', or acknowledges them but does not fully incorporate them into their models. Neurobiologists testing for imaging loss seem to assume that visual recognition, describing objects, and free-hand drawing require the forming of conscious images. The intuition that 'the psyche never thinks without an image.... the reasoning mind thinks its ideas in the form of images' (Aristotle) has a long tradition (...) in philosophical psychology, from Aristotle through the British empiricists to the British-empiricist-inspired introspection paradigm of Titchener. The massive shift in early experimental psychology to the introspective-antagonistic paradigm of Watson's behaviourism, may have sprung from the contrary intuition that no one thinks in mental images. In both cases, people seemed to assume that what is in one's own mind is in everybody's mind. A third, mediating, intuition - that some people do not think with conscious mental imagery -- seems to be confirmed by empirical studies on many levels. From the early imagery interviews of Francis Galton through many modern surveys, including my own, a consistent diversity of self-reports on ones own mental imagery abilities suggests that some 2-5% of people are very poor- or non-visual- imagers who, yet, maintain normal visual recognition abilities. Comparable estimates have been made in auditory and other imagery modalities. (shrink)

The first truly introductory text on Lyotard, this book situates Lyotard's interventions in the postmodern debate in the wider context of his rethinking of the politics of representation. Bill Readings examines Lyotard's relationship to structuralism, Marxism and semiotics, and contrasts his work with the literary deconstruction of Paul de Man; he positions Lyotard's work so as to draw out the implications of poststructurlaism's attention to _difference_ in reading. Lyotard's willingness to question the political and examine the relationship between art (...) and politics is shown to undermine the charge that deconstruction abdicates political and social articulation.
