Psychedelic substances elicit powerful, uncanny conscious experiences that are thought to possess therapeutic value. In those who undergo them, these altered states of consciousness often induce shifts in metaphysical beliefs about the fundamental structure of reality. The contents of those beliefs range from contentious to bizarre, especially when considered from the point of view of naturalism. Can chemically induced, radically altered states of consciousness provide reasons for or play some positive epistemic role with respect to metaphysical beliefs? In this paper, (...) I discuss a view that has been underexplored in recent literature. I argue that psychedelic states can be rationally integrated into one’s epistemic life. Consequently, updating one’s metaphysical beliefs based on altered states of consciousness does not have to constitute an instance of epistemic irrationality. (shrink)

Even after Willard Quine’s critique of the analytic-synthetic distinction in “Two Dogmas of Empiricism,” Wilfrid Sellars maintained some forms of analyticity or truth in virtue of meaning. In this article, I aim to reconstruct (a) his neglected account of the analytic-synthetic distinction and the revisability of analytic sentences, (b) its connection to his inferentialist account of meaning, and (c) his response to Quine. While Sellars’s account of the revisability of analytic sentences bears certain similarities to Carnap’s and Grice and Strawson’s (...) accounts, it is still striking in that it is part of his broader picture of how our language develops dynamically in our ongoing inquiry. I aim to show how it relates to his account of how the diachronic continuity in meaning, language, or conceptual framework can be preserved through a revision of analytic sentences and to his evolutionary account of the development of our language or conceptual framework.

Roche and Sober (2013; 2014; 2017; 2019) have offered an important new argument that explanatoriness lacks confirmatory significance. My aim in this paper is not only to contend that their argument fails to show that in confirmation ‘there is nothing special about explanatoriness’ (Roche & Sober, 2017: 589), but also to reveal what is special confirmationwise about explanatoriness. I will argue that much of the heavy work in Roche and Sober's argument is done by the dichotomy into which they carve (...) up the philosophical options: either explanatory considerations per se are confirmatorily relevant or they acquire whatever confirmatory significance they may possess only by way of background beliefs and so no differently from non‐explanatory considerations. I will argue that this is a false dichotomy: Explanatoriness per se can have confirmatory relevance even while explanatory considerations acquire their confirmatory relevance only through background opinions. Furthermore, there is ‘something special’ about the background opinions concerning explanations that allow explanatoriness in itself to have confirmatory impact. Unlike other sorts of background, having some background opinions expressly about explanations is indispensable to being an observer at all. (shrink)

Wilfrid Sellars is usually read as claiming that only the unobservable, theoretical objects which science would postulate at the ideal end of inquiry are real. Against this, Willem deVries has suggested that we can develop a notion of practical reality in the context of Sellars's philosophy which would pertain primarily to commonsense objects. I use deVries's suggestion as a foil to clarify Sellars's own commitments about the practical. I show that the notion of practical reality is not necessary to secure (...) the ultimate legitimacy of practical concepts. We can retreat to the less committed notion of practical truth. I argue that the notion of practical truth may not be sufficient to ensure that ultimately legitimate practical concepts are commonsense concepts in Sellars's framework. Nevertheless, deVries's suggestion highlights that Sellars's vision of an ultimate conceptual system may have been richer than is often thought. (shrink)

This paper draws on the phenomenological-hermeneutical approaches to philosophy of science to develop realist perspectivism, an integration of experimental realism and perspectivism. Specifically, the paper employs the distinction between “manifestation” and “phenomenon” and it advances the view that the evidence of a real entity is “explorable” in order to argue that instrumentally-mediated robust evidence indicates real entities. Furthermore, it underpins the phenomenological notion of the horizonal nature of scientific observation with perspectivism, so accounting for scientific pluralism even in the cases (...) of inconsistent models. Overall, realist perspectivism is proposed as the way to go for (phenomenologically-hermeneutically minded) philosophers of science. (shrink)

Wilfrid Sellars’ denunciation of the Myth of the Given was meant to clarify, against empiricism, that perceptual episodes alone are insufficient to ground and justify perceptual knowledge. Sellars showed that in order to accomplish such epistemic tasks, more resources and capacities, such as those involved in using concepts, are needed. Perceptual knowledge belongs to the space of reasons and not to an independent realm of experience. Dan Hutto and Eric Myin have recently presented the Hard Problem of Content as an (...) ensemble of reasons against naturalistic accounts of content. In a nutshell, it states that covariance relations—even though they are naturalistically acceptable explanatory resources—do not constitute content. The authors exploit this move in order to promote their preferred radical enactivist and anti-representationalist option, according to which, basic minds—the lower stratum of cognition—do not involve content. Although it is controversial to argue that the Hard Problem of Content effectively dismisses naturalistic theories of representation, a central aspect of it—the idea that information as covariance does not suffice to explain content—finds support among the defenders of classical cognitive representationalism, such as Marcin Miłkowski. This support—together with the acknowledgment this remark about covariance is a point already made by Sellars in his criticism of the Myth of the Given—has a number of interesting implications. Not only is it of interest for the debates about representationalism in cognitive science, where it can be understood as an anticipatory move, but it also offers some clues and insights for reconsidering some issues along Sellarsian lines—a conflation between two concepts of representation that is often assumed in cognitive science, a distinction between two types of relevant normativities, and a reconsideration of the naturalism involved in such explanations.

In Plato’s Timaeus, two different theories – the Receptacle theory and the geometrical particle theory – are presented to explain change in the natural world. In this paper, I argue that there is tension between the two theories. After examining several possible solutions for this tension, I conclude that Plato does not present it as something ready to be solved within the dialogue but, rather, as something to be understood in a way that maintains both theories. Finally, I also argue (...) that the contrast between the two theories in the Timaeus derives from a similar contrast in the Phaedo. (shrink)

ABSTRACT This paper compares Spinoza with Daniel Dennett and uncovers a number of striking parallels. Genevieve Lloyd’s recent work on Spinoza reveals a picture of a philosopher that anticipated many of Dennett’s later ideas. Both share a fervent opposition to Descartes’ conception of mind and body and endorse a strikingly similar naturalist philosophy. It is the goal of this paper to tease out these connections and once again highlight the richness of a Spinozist lens of the world.

Understanding, for Kant, does not intuit, and intuition—which involves empirical information, i.e., sense-data—does not entail thinking. What is crucial to Kant’s famous claim that intuitions without concepts are blind and concepts without intuitions are empty is the idea that we have no knowledge unless we combine concepts with intuition. Although concepts and intuition are radically separated mental powers, without a way of bringing them together (i.e., synthesis) there is no knowledge for Kant. Thus Kant’s metaphysical-scientific dualism: (scientific) knowledge is limited (...) to the world of phenomena—the world of appearance—while the thing-in-itself is unknowable because there is no intuition that can correspond to the it. This paper sets to cull Béatrice Longuenesse’s recent work on the first-person ‘I’ and put forth a novel Kantian approach to the first-person reference of mental states, working in the tradition of P.F. Strawson, Rudolf Carnap, and Wilfrid Sellars, while offering an empirical study of deafferentation to ground the thesis that the binding of representations is separate from phenomenal consciousness. Accordingly, we stake a kind of self-consciousness vis-à-vis the Fundamental Reference-Rule qua apperception that, while intimately connected to consciousness of one’s own body, apperception is nevertheless distinct from it and is, moreover, the condition for any use of ‘I’. We compliment neuroscientist Oliver Sacks’ research with Ned Block’s recent work on “no-post‐perceptual cognition” and attentional variation to couch Kant’s schema in perceptual psychology. We navigate Kant’s work on intuitions (viz. sensation, perception, and the empirical side of the cognitive faculties) and indirect realism/weak representationism first via Sellars’ naturalization of Kant’s inaccessible thing-in-itself, before challenging Sellars’ functionalist and inferentialist conception of perception and discursive intentionality. We ultimately endeavor to conceptualize the limit-conditions regarding our having reportable knowledge about our access to percepts and concepts. (shrink)

What is the primary intellectual aim of philosophy? The standard view is that philosophy aims to provide true answers to philosophical questions. But if our aim is to settle controversy by answering such questions, our discipline is an embarrassing failure. Moreover, taking philosophy to aim at providing true answers to these questions leads to a variety of puzzles: How do we account for philosophical expertise? How is philosophical progress possible? Why do job search committees not care about the truth or (...) falsity of a candidate’s philosophical views? We argue that philosophy does not aim at discovering true answers to philosophical questions. Instead, its primary intellectual aim is understanding. We argue that many familiar aspects of philosophy become intelligible once we accept this hypothesis. (shrink)

This article has two aims: to bring Judith Butler and Wilfrid Sellars into conversation; and to argue that Butler's poststructuralist critique of feminist identity politics has metaphilosophical potential, given her pragmatic parallel with Sellars's critique of conceptual analyses of knowledge. With regard to, I argue that Butler's objections to the definitional practice constitutive of certain ways of construing feminism is comparable to Sellars's critique of the analytical project geared toward providing definitions of knowledge. Specifically, I propose that moving away from (...) a definition of woman to what one may call poststructuralist sites of woman parallels moving away from a definition of knowledge to a pragmatic account of knowledge as a recognizable standing in the normative space of reasons. With regard to, I argue that the important parallels between Butler's poststructuralist feminism and Sellars's antirepresentationalist normative pragmatism about knowledge enable one to think of her poststructuralist feminism as mapping out pragmatic cognitive strategies and visions for doing philosophy. This article starts a conversation between two philosophers whom the literature has yet to fully introduce to each other. (shrink)

In this article I discuss Daniel Dennett’s view of the role of natural language in the evolution of the human mind. In contrast with defenders of the Language of Thought Hypothesis, Dennett claims that natural language is an evolved tool for communication, originating in behavioural habits of which users were initially not aware. Once in place, such habits changed access to information in human brains and were crucial for the evolution of human consciousness. I assess Dennett’s approach from the viewpoint (...) of philosophy of mind and language and consider its ontological implications. I contrast Dennett’s views with the universalist and internalist claims of Jerry Fodor and Noam Chomsky and show how, by appealing to memes and cultural evolution, Dennett resists such claims. I then analyse how this picture goes together with a deflationary view of consciousness. I end by pointing out that although Dennett’s global picture seems to point towards a pluralistic ontology, he himself refrains from taking such a step. (shrink)

Psychometric g—a statistical factor capturing intercorrelations between scores on different IQ tests—is of theoretical interest despite being a low-fidelity model of both folk psychological intelligence and its cognitive/neural underpinnings. Psychometric g idealizes away from those aspects of cognitive/neural mechanisms that are not explanatory of the relevant variety of folk psychological intelligence, and it idealizes away from those varieties of folk psychological intelligence that are not generated by the relevant cognitive/neural substrate. In this manner, g constitutes a high-fidelity bridge model of (...) the relationship between its two targets and, thereby, helps demystify the relationship between folk and scientific psychology.

Patrick Heelan, with background in quantum theory and in hermeneutic phenomenology, investigated not only the hermeneutical philosophy of science but also the parallels between quantum mechanics and human experience in general and the logic of changes of worldview. Heelan’s closeness to Aristotle and Lonergan, often neglected, is discussed, and issues concerning Heelan’s treatment of the social context of science are raised.

ABSTRACT: I contend that Sellars defends a uniquely Kantian naturalist outlook both in general and more particularly in relation to the nature and status of what he calls ‘epistemic principles’; and I attempt to show that this remains a plausible and distinctive position even when detached from Sellars’s quasi-Kantian transcendental idealist contention that the perceptible objects of the manifest image strictly speaking do not exist, i.e., as conceived within that common sense framework. I first explain the complex Kant-inspired sense in (...) which Sellars did not take the latter thesis concerning the objects of the manifest image to apply, at least in certain fundamental respects, to persons. In this primary Kantian sense, I suggest, persons as thinkers and agents exist univocally across both the manifest and scientific images, and this in principle would enable an integration of persons within a multi-leveled naturalistic ontology, one that is independent of Sellars’s quasi-Kantian transcendental idealist thesis. Finally, I examine in some detail how this defensible blend of Kantian and naturalist themes turns out to be what is fundamental in Sellars’s complex and controversial views on the nature and status of epistemic principles.

According to the idealist, facts about phenomenal experience determine facts about the physical world. Any such view must account for illusions: cases where there is a discrepancy between the physical world and our experiences of it. In this paper, I critique some recent idealist treatments of illusions before presenting my own preferred account. I then argue that, initial impressions notwithstanding, it is actually the realist who has difficulties properly accounting for illusions.

From antiquity through the twentieth century, philosophers have hypothesized that, intuitively, it is harder to know negations than to know affirmations. This paper provides direct evidence for that hypothesis. In a series of studies, I found that people naturally view negations as harder to know than affirmations. Participants read simple scenarios and made judgments about truth, probability, belief, and knowledge. Participants were more likely to attribute knowledge of an outcome when framed affirmatively than when framed negatively. Participants did this even (...) though the affirmative and negative framings were logically equivalent. The asymmetry was unique to knowledge attributions: it did not occur when participants rated truth, probability, or belief. These findings show new consequences of negation on people’s judgments and reasoning and can inform philosophical theorizing about the ordinary concept of knowledge. (shrink)

This paper makes a phenomenological contribution to the distinction between personal and subpersonal types of explanation. I expound the little-known fact that Husserl gives an account of personal level explanation via his exposition of our capacity to express the understanding of another’s motivational nexus when we are in the personalistic attitude. I show that Husserl’s unique exposition of the motivational nexus conveys its concrete, internally coherent, and intentional nature, involving relationships amongst the sense contents of acts of consciousness. Moreover, the (...) motivational nexus is a generative space of possibility and choice. I show that, for these reasons, motivational explanation is not causal, nor deductive nomological, nor does it reduce to subpersonal explanation. I finish with the comment that the uniqueness of personal level explanation points towards the possibility that the human sciences ought also employ types of explanations not found in natural sciences.

In this journal, Robert Smithson argues that considerations stemming from Kantian and post-Kantian idealism undermine naturalistic arguments that seek to debunk elements of the ‘manifest image’ in favour of the ‘scientific image’. The idealist tradition, on this view, holds that philosophy’s task is to uncover and clarify the principles and norms which underlie different forms of inquiry, and is thus well placed to dispel the apparent ‘placement’ problems that stem from the collision of our ordinary worldview with contemporary philosophical naturalism. (...) Smithson also argues that this idealist critique of naturalism is preferable to the Liberal Naturalist critique of naturalism. In this response, I argue that Smithson’s view contains a gap which the naturalist can exploit to evade idealist critique, but that a Hegelian idealism contains no such gap, making it the better idealist choice. Further, I argue that that Hegelian idealism is itself plausibly a version of liberal naturalism. (shrink)

In this paper I offer a coherentist justification of induction along the lines of a Sellarsian coherence theory. On this coherence theory, a proposition is justified if we can answer all objections raised against it in our social practice of demanding justification and responding to such demands. On the basis of this theory of justification, I argue that we are justified in accepting the uniformity of nature partly because we have no alternative but to accept it for rationally pursuing our (...) epistemic goal. In addition, my coherentist view explains which inductive inferences it is rational to accept. Furthermore, my coherentist view also explains why we can hardly determine a particular numerical value x such that we can draw the conclusion ‘it is rational to accept that p’ from the premise ‘the numerical probability of p is greater than or equal to x’.

Scholars have rejected Wilfrid Sellars’ argument for an ontology of absolute processes on the grounds that it relies on a dubious and dogmatic appeal to the homogeneity of color. Borrowing from Rosenthal’s recent defense, but ultimate rejection of homogeneity, I defend this claim of on Sellarsian/Kantian transcendental grounds, and reconstruct the remainder of his argument. I argue that Sellars has good reason to suppose that homogeneity is a necessary condition of any possible experience, including indirect experience of theoretical-explanatory posits, and (...) therefore good reason to hold that Reductive Materialism, as he conceives it, is an untenable account of color. The remainder of his argument aims to answer the question of what the metaphysical relation is between the state of an experiencing subject that we take color to be and the colorless microphysical particles that we take to constitute that subject. After rejecting Substance Dualism, Epiphenomenalism, and Wholistic or Emergent Materialism as explanatorily inadequate, Sellars proposes that both color-states and micro-physical particles should be understood as manifestations of an underlying ontology on absolute processes.

Representationalism holds that a perceptual experience's qualitative character is identical with certain of its representational properties. To date, most representationalists endorse atomistic theories of perceptual content, according to which an experience's content, and thus character, does not depend on its relations to other experiences. David Rosenthal, by contrast, proposes a view that is naturally construed as a version of representationalism on which experiences’ relations to one another determine their contents and characters. I offer here a new defense of this holistic (...) representationalism, arguing that some objections to atomistic views are best interpreted as supporting it. (shrink)

This paper analyses the anti-reductionist argument from renormalisation group explanations of universality, and shows how it can be rebutted if one assumes that the explanation in question is captured by the counterfactual dependence account of explanation.

A pressing philosophical problem is how to respond to the existential, anxiety and disenchantment resulting from a naturalistic worldview that eschews transcendent foundations for meaning and value. This problem is becoming more urgent as the popularization of neuroscientific findings renders a disenchanted conception of human beings ever more vivid, compelling, and widespread. I argue that the study of transformative experiences occasioned by classic psychedelic drugs such as lysergic acid diethylamide and psilocybin may reveal the nature of a viable practical solution (...) to this problem. Despite the apparent centrality of nonnaturalistic metaphysical apprehensions to psychedelic transformation, findings from psychedelic research suggest that key elements of psychedelic or “entheogenic” spirituality are consistent with naturalism. These include disruption to neurocognitive mechanisms underpinning the sense of self, and consequent experiences of self-transcendence and of the decoupling of attention from personal concerns. This liberation of attention can result in the availability of broader perspectives and the development of wonder and appreciation for life. (shrink)

This paper develops an appearance view of perception (focusing on vision). When we see an object, we see it by having it appear some way to us. We see the object, not the appearance; but we see the object via the appearance. The appearance is subjectively conditioned: aspects of it depend on attributes of the subject. We mentally have the appearance and can reflect on it as an appearance. But in the primary instance, of veridical perception, it is the object (...) that we focus on and experience. I contrast this view with naive realism (sometimes called disjunctivism) (Brewer, Campbell, Noe) and with intentionalist or representationalist views, which I call the physical content view (Dretske, Tye, Crane, Hill, Burge). I agree with these views in rejecting sense-data intermediaries and in affirming direct perception, but I argue that direct perception occurs via appearances, making mine a critical direct realism. The other views attempt to explain the spatial content of perception (shape, size, distance) entirely through the physical properties of objects and their physical relation to the perceiver (viewing position). I argue instead that there are ineliminably subjective aspects of normal spatial perception, which are systematically manifested as a lack of full phenomenal constancy. This systematic underconstancy can’t be accounted for at all by a consistent naive realism; for the physical content view, it requires that most of our ordinary perception is classified as illusory, violating the spirit of that view. Accepting phenomenal underconstancy as pervasive, I suggest that our ability to perceive the mind-independent properties of objects depends on developed conceptual abilities. In the final section, I compare my appearance view with the adverbialism of Chisholm and the critical direct realism of Roy Wood Sellars. (shrink)

In this paper I investigate how philosophy can speak for children and how children can have a voice in philosophy and speak for philosophy. I argue that we should understand children as responsible rational individuals who are involved in their own philosophical inquiries and who can be involved in our own philosophical investigations—not because of their rational abilities, but because we acknowledge them as conversational partners, acknowledge their reasons as reasons, and speak for them as well as let them speak (...) for us and our rational community. In order to argue this I turn, first, to Gareth Matthews’ philosophy of childhood and suggest a reconstruction of some of his concepts in line with the philosophy of Stanley Cavell. Second, in order to examine more closely our conceptions of rationality and our pictures of children, I consider the children’s books, The Lorax and Where is My Sister? and Henrik Ibsen’s play, The Wild Duck.

Pragmatism has played only a small role in the half century and more of the science‐and‐religion dialogue, in part because pragmatism was at a low ebb in the 1950s. Even though Jamesean pragmatism in particular is experiencing a resurgence, owing partly to the work of Rorty and Putnam, it remains inconspicuous in the dialogue. Excepting artificial intelligence and artificial life, computer science also has not played a large role in the dialogue. Recent research into the foundations of object‐oriented programming, however, (...) shows this increasingly pervasive practice possesses an implicit pragmatist epistemology. Although science will have to become more computational, it will have to come to terms with both object‐oriented computing and its implicit pragmatism, which in turn supports the conclusion that we have fresh warrant for recasting the science‐and‐religion dialogue in Jamesean pragmatist terms. Some preliminary consequences of such a recasting of the dialogue are explored. (shrink)

Physical realism is the thesis that the world is more or less as present‐day physical theory says it is, i.e. a mind‐independent reality, that consists fundamentally of physical objects that have causal powers, are located in space and time, belong to natural kinds, and interact causally with each other in various natural kinds of ways. It is thus a modern form of physicalism that takes due account of the natural kinds structure of the world. It is a thesis that many (...) present‐day scientific realists would surely accept. Indeed, some might say that physical realism just is scientific realism, but under another name. However, the argument that is presented for physical realism is not the standard one for scientific realism. It is not a two‐stage argument from the success of science to the truth of scientific theories to the reality of the entities postulated in these theories. It is more powerful than this, because it is more direct, and its premisses are more secure. It is more direct, because it develops what is basically a physicalist ontology as the only plausible metaphysical explanation of the new scientific image of the world. It is more secure, in that it does not depend, as the standard argument does, on any doubtful generalisations about the nature or role of scientific theory. (shrink)

Alasdair MacIntyre's expression of the “profound gratitude we all owe to Althusser for having brought French Marxism back into dialogue with the rest of French philosophy”, important as it may be for a host of reasons, did not try to make Althusser's philosophy particularly attractive to philosophers of science. However, the present selection of essays does precisely this: It is almost ideally designed to mark the beginnings of an effective encounter of this particular brand of “French Marxism” with philosophy of (...) science.

The major part of our beliefs and our knowledge of the world is based on, or grounded in, sensory experience. But, how is it that we can have perceptual beliefs that things are thus and so, and, moreover, be justified in having them? What conditions must experience satisfy to rationally warrant, and not merely to cause, our beliefs? Against the currently very popular contention that experience itself already has to be propositionally and conceptually structured, I will rehabilitate the claim that (...) there is given element in experience which is independent of thought and which is possessed of a distinctive nonpropositional and nonconceptual content. Further, I will argue that this given element is indeed fit to play a significant evidential role in the justification of our beliefs about the world. (shrink)

I argue against a class of philosophical views of color perception, especially insofar as such views posit the existence of color sensations. I argue against the need to posit such nonconceptual mental intermediaries between the stimulus and the eventual conceptualized perceptual judgment. Central to my arguments are considerations of certain color illusions. Such illusions are best explained by reference to high-level, conceptualized knowledge concerning, for example, object identity, likely lighting conditions, and material composition of the distal stimulus. Such explanations obviate (...) the need to appeal to nonconceputal mental links in the causal chains eventuating in conceptualized color discriminations. (shrink)

I compare Sellars’s criticism of the ‘myth of the given’ with Quine’s criticism of the ‘two dogmas’ of empiricism, that is, the analytic–synthetic distinction and reductionism. In Sections I to III, I present Quine’s and Sellars’s views. In IV to X, I discuss similarities and differences in their views. In XI to XII, I show that Sellars’s arguments against the ‘myth of the given’ are incompatible with Quine’s rejection of the analytic–synthetic distinction.

There is a widespread view that in order to be rational we must mostly know what we believe. In the probabilistic tradition this is defended by arguments that a person who failed to have this knowledge would be vulnerable to sure loss, or probabilistically incoherent. I argue that even gross failure to know one's own beliefs need not expose one to sure loss, and does not if we follow a generalization of the standard bridge principle between first-order and second-order beliefs. (...) This makes it possible for a subject to use probabilistic decision theory to manage in a rational way cases of potential failure of this self-knowledge, as we find in implicit bias. Through such cases I argue that it is possible for uncertainty about what our beliefs are to be not only rationally permissible but advantageous. (shrink)

Many idealists have thought that realism raises epistemological problems. The worry is that, if it is possible for truths about ordinary objects to outstrip our experiences in the ways that realists typically suppose, we could never be justified in our beliefs about objects. Few contemporary theorists find this argument convincing; philosophers have offered a variety of responses to defend the epistemology of our object judgments under the assumption of realism. But in this paper, I offer a new type of epistemic (...) argument against realism which is immune to the standard responses in the literature. In addition to raising a challenge for realism, the epistemology of our object judgments has implications for how the idealist should develop her own positive metaphysical view. So in the second half of this paper, I discuss how the idealist should understand the dependence between objects and our experiences if she is to secure epistemic advantages over the realist.

Early twentieth-century philosophers of perception presented their naïve realist views of perceptual experience in anti-Kantian terms. For they took naïve realism about perceptual experience to be incompatible with Kant’s claims about the way the understanding is necessarily involved in perceptual consciousness. This essay seeks to situate a naïve realist account of visual experience within a recognisably Kantian framework by arguing that a naïve realist account of visual experience is compatible with the claim that the understanding is necessarily involved in the (...) perceptual experience of those rational beings with discursive intellects. The resultant view is middle way between recent conceptualist and non-conceptualist interpretations of Kant, holding that the understanding is necessarily involved in the kind of perceptual consciousness that we, as rational beings, enjoy whilst allowing that the relations of apprehension which constitute perceptual consciousness are independent of acts of the understanding.

Wilfrid Sellars’ philosophical system joins issues that have often been regarded as incompatible or at least in mutual tension. Two of these are his holistic approach to language and knowledge on the one hand and his realism on the other hand. In my paper I first outline this tension and then present a number of steps, including the rejection of semantic relations, picturing and the defense of realism, which can help us to accommodate it. I highlight the payoff of these (...) steps for the question to be solved. In the last part of the paper I detect new and more refined tensions revealed by Sellars’ solution. I identify possible dissonances between his Kantian and his naturalist treatment of causality as well as between his two ways of conceiving of language arguing that these new questions furnish a more interesting approach to our initial problem.

In the philosophy of perception, direct realism has come into vogue. Philosophical authors assert and assume that what their readers want, and what anyone should want, is some form of direct realism. There are disagreements over precisely what form this direct realism should take. The majority of positions in favor now offer a direct realism in which objects and their material or physical properties constitute the contents of perception, either because we have an immediate or intuitive acquaintance with those objects (...) and properties, or because our perceptual states have informational content that represents the properties of those objects (and which is not itself an object of perception and has no specifically subjective aspect). This paper considers various forms of perceptual realism, including, for purposes of comparison, the largely abandoned indirect or representative realism. After surveying the variety of perceptual realisms and considering their various commitments, I introduce some considerations concerning the phenomenology of visual space that cause trouble for most forms of direct realism. These considerations pertain to the perception of objects in the distance and, secondarily, to the perception of shapes at a slant. I argue that one of the lesser known varieties of perceptual realism, critical direct realism, can meet the challenges offered by the facts of spatial perception. (shrink)

This essay argues that acknowledging the existence of mind-independent facts is a matter of vital importance, in that acquiescence before the layout of the world is something demanded of knowing agents from the most elementary empirical deliverance to the most abstract construct. Building on the idea that normativity requires the presence of more than one option to choose from, the essay shows how the cessation of one's life is the disjunctive alternative of any experiential episode. This much has been missed, (...) it argues, because of a generalized failure to appreciate how even the simplest atomic contents embroil their subjects in acts of assent. Its account thus casts a new light on relativism and skepticism, revealing them to be provisional luxuries supported only by the cognitive labor of others. (shrink)

One of the central debates in contemporary Kant scholarship concerns whether Kant endorses a “conceptualist” account of the nature of sensory experience. Understanding the debate is crucial for getting a full grasp of Kant's theory of mind, cognition, perception, and epistemology. This paper situates the debate in the context of Kant's broader theory of cognition and surveys some of the major arguments for conceptualist and non-conceptualist interpretations of his critical philosophy.

In a famous passage (A68/B93), Kant writes that “the understanding can make no other use of […] concepts than that of judging by means of them.” Kant's thought is often called the thesis of the priority of judgments over concepts. We find a similar sounding priority thesis in Frege: “it is one of the most important differences between my mode of interpretation and the Boolean mode […] that I do not proceed from concepts, but from judgments.” Many interpreters have thought (...) that Frege's priority principle is close to (or at least derivable from) Kant's. I argue that it is not. Nevertheless, there was a gradual historical development that began with Kant's priority thesis and culminated in Frege's new logic. (shrink)

Some recently popular accounts of perception account for the phenomenal character of perceptual experience in terms of the qualities of objects. My concern in this paper is with naturalistic versions of such a phenomenal externalist view. Focusing on visual spatial perception, I argue that naturalistic phenomenal externalism conflicts with a number of scientific facts about the geometrical characteristics of visual spatial experience.

This paper serves to introduce the papers from the symposium by the same title, by describing the sort of work done in philosophy of psychology conceived as a branch of the philosophy of science, distinguishing it from other discussions of psychology in philosophy, and criticizing the claims to set limits on scientific psychology in the largely psychologically uninformed literatures concerning "folk psychology' and "wide" and "narrow" content. Philosophy of psychology as philosophy of science takes seriously and analyzes the explanatory structures, (...) conceptual problems, and evidentiary practices of extant scientific psychology.

Students of perception have long puzzled over a range of cases in which perception seems to tell us distinct, and in some sense conflicting, things about the world. In the cases at issue, the perceptual system is capable of responding to a single stimulus — say, as manifested in the ways in which subjects sort that stimulus — in different ways. This paper is about these puzzling cases, and about how they should be characterized and accounted for within a general (...) theory of perception. After rehearsing the sort of case at issue (§1), I’ll examine critically some of the strategies by which philosophers and perceptual psychologists have attempted to account for them (§2). Finally, I’ll present an alternative computational account of the puzzle cases, argue that this view is superior to its competitors, and examine some of its implications (§3). (shrink)
