This chapter starts by restating the causal-hallucinatory argument against naive realism. This argument depends on the possibility of “philosophers' hallucinations.” It draws attention to the role of what the chapter refers to as the nonarbitrariness of philosophers' hallucinations in supporting this argument. The chapter then discusses three attempts to refute the argument. Two of them, those associated with John McDowell and with Michael Martin, are explicitly forms of disjunctivism. The third, exemplified by Mark Johnston, has, the chapter claims, disjunctivist features. (...) None of these responses to the argument is plausible. (shrink)

There is a view abroad on which perceptual experience has representational content in this sense: in it something is represented to the perceiver as so. On the view, a perceptual experience has a face value at which it may be taken, or which may be rejected. This paper argues that that view is mistaken: there is nothing in perceptual experience which makes it so that in it anything is represented as so. In that sense, the senses are silent, or, in (...) Austin's term, dumb. Perceptual experience is not as such either veridical or delusive. It may mislead, but it does not take representation to accomplish that. (shrink)

‘What is characteristic of every mental activity’, according to Brentano, is ‘the reference to something as an object. In this respect every mental activity seems to be something relational.’ But what sort of a relation, if any, is our cognitive access to the world? This question – which we shall call Brentano’s question – throws a new light on many of the traditional problems of epistemology. The paper defends a view of perceptual acts as real relations of a subject to (...) an object. To make this view coherent, a theory of different types of relations is developed, resting on ideas on formal ontology put forward by Husserl in his Logical Investigations and on the theory of relations sketched in Smith's "Acta cum fundamentis in re". The theory is applied to the notion of a Cambridge change, which proves to have an unforeseen relevance to our understanding of perception. (shrink)

It will be the thesis of this paper that there are among our mental acts some which fall into the category of real material relations. That is: some acts are necessarily such as to involve a plurality of objects as their relata or fundamenta. Suppose Bruno walks into his study and sees a cat. To describe the seeing, here, as a relation, is to affirm that it serves somehow to tie Bruno to the cat. Bruno's act of seeing, unlike his (...) feeling depressed, his putative thinking-about-Santa-Claus or his musing, abstractedly, about the tallest spy, has at least two fundamenta: it is, as a matter of necessity, dependent for its existence upon both Bruno himself and the cat that he sees. This idea will naturally raise echoes of Russell's doctrine of knowledge by acquaintance. 'I am acquainted with an object', Russell tells us, 'when I have a direct cognitive relation to that object, i. e. when I am directly aware of the object itself' (1918, p. 209). And indeed a distinction in many ways like that between acquaintance and description will find a place within the theory here projected, but there are crucial differences. (shrink)

Husserl saw the Cartesian critique of scepticism as one of the eternal merits of Descartes’ philosophy. In doing so, he accepted the legitimacy of the very idea of a universal doubt, and sought to present as an alternative to it a renewed, specifically phenomenological concept of self-evidence, making it possible to obtain an unshakable foundation for the edifice of knowledge. This acceptance of the skeptical problem underlies his entire conceptual framework, both before and after the transcendental turn, and especially the (...) immanence/transcendence distinction, i.e., the very basis of intentionality. In taking as its starting point an analysis of perception, the article puts forth a certain number of phenomenological arguments in order to put into question the validity of the skeptical problem and, therefore, of the Husserlian conceptual framework; it defends, in the first place, a disjunctive conception of perception and, in the second place, a holism of experience.

Claude Romano and Andrea Staiti have recently discussed Husserl’s account of perception in relation to debates in current analytic philosophy between so-called “conjunctivists” and “disjunctivists”. Romano and Staiti offer strikingly different accounts of the nature of illusion and hallucination, and opposing readings of Husserl. Romano thinks hallucinations and illusions are fleeting, fragile phenomena, while Staiti claims they are inherently retrospective phenomena. Romano reads Husserl as being committed to a form of conjunctivism that Romano rejects in favour of a version of (...) disjunctivism. Staiti, by contrast, claims that, from a Husserlian viewpoint, conjunctivism and disjunctivism are equally untenable. I suggest that both Romano and Staiti offer implausible accounts of illusions and hallucinations, and deliver premature verdicts on Husserl in relation to the analytic debates on perception.

Philosophical interest in the structure of perception is motivated by questions such as these: How does perception function to constrain and justify our empirical theories? How is it possible to perceive an extended process, when at any given moment of our perceiving it only one of its temporal phases is impinging on our senses? What determines the object or objects of perception - those things our experiences are about? The need to answer these and other questions about perception in a (...) satisfactory manner provides adequacy conditions for a theory of perception. (shrink)

A common objection to sense-datum theories of perception is that they cannot give an adequate account of the fact that introspection indicates that our sensory experiences are directed on, or are about, the mind-independent entities in the world around us, that our sense experience is transparent to the world. In this paper I point out that the main force of this claim is to point out an explanatory challenge to sense-datum theories.

This paper examines Husserl’s theory of intentionality as it is developed in Logical Investigations and other early writings. In Section 1, the author attempts to capture the core of Husserl’s concept of intentionality. Section 2 is devoted to a detailed analysis of the account of intentional relation developed in the fifth Investigation. In Section 3, the author tries to flesh out what is meant by the claim in the sixth Investigation that the designation ‘object’ is a relative one. In Section (...) 4, the author discusses Husserl’s conception of intentionality in light of the mereology outlined in the third Investigation. In Section 5, the author explains how Husserl criticizes the so-called theory of immanent objects and how he addresses the problem of non-existents. In Section 6, the author argues that a phenomenological theory of intentionality grounded in Husserl’s insights cannot be a non-relational one. (shrink)

Many philosophers are skeptical about disjunctivism —a theory of perceptual experience which holds roughly that a situation in which I see a banana that is as it appears to me to be and one in which I have a hallucination as of a banana are mentally completely different. Often this skepticism is rooted in the suspicion that such a view cannot adequately account for the bad case—in particular, that such a view cannot explain why what it’s like to have a (...) hallucination can be exactly like what it’s like to have a veridical experience, that it cannot explain why the hallucination I have in the bad case is subjectively indistinguishable from the kind of experience I have in the good case, and that it cannot offer a viable account of the nature of hallucination. -/- In this paper, I argue that a proper formulation of disjunctivism can avoid these objections. Disjunctivism should be formulated as the weakest claim required to preserve its primary motivation, viz., Naïve Realism—the view that veridical experience fundamentally consists in the subject perceiving entities in her environment. And the weakest claim required to preserve Naïve Realism allows for many sorts of commonalities across the good and hallucinatory cases, commonalities that can be marshaled in responding to the objections. Most importantly, disjunctivism properly formulated is compatible with “positive” accounts of the nature of hallucination. (shrink)

This paper explores the close connection in early phenomenology between the problem of objectless presentations and the concept of intentional objects. It clarifies how this basic concept of Husserl’s early phenomenology emerged within the horizons of Bolzano’s logical objectivism, Brentano’s descriptive psychology, Frege’s mathematical logicism, Twardowski’s psychological representationalism, and Meinong’s object theory. It shows how in collaboration with these thinkers Husserl argued that a theory of intentionality is incomplete without a concept of the intentional object. It provides a brief history (...) of the concept of intentional objects in the philosophical logic of the nineteenth century that demonstrates its relevance to the problem of objectless presentations in the early phenomenology of the twentieth century. It suggests that Husserl accepts Bolzano’s objectivism and Frege’s logicism, rejects Brentano’s conception of immanent objects and Twardowski’s notion of representational pictures, and ignores Meinong’s theory of objects. Thus the paper employs the formation of Husserl’s concept of the intentional object to enhance the understanding of the historical and philosophical relationships between early phenomenology and contemporaneous philosophical movements.

Recent debates between representational and relational theories of perceptual experience sometimes fail to clarify in what respect the two views differ. In this essay, I explain that the relational view rejects two related claims endorsed by most representationalists: the claim that perceptual experiences can be erroneous, and the claim that having the same representational content is what explains the indiscriminability of veridical perceptions and phenomenally matching illusions or hallucinations. I then show how the relational view can claim that errors associated (...) with perception should be explained in terms of false judgments, and develop a theory of illusions based on the idea that appearances are properties of objects in the surrounding environment. I provide an account of why appearances are sometimes misleading, and conclude by showing how the availability of this view undermines one of the most common ways of motivating representationalist theories of perception.

Abstract: How exactly should the relation between a veridical perception and a corresponding hallucination be understood? I argue that the epistemic notion of ‘indiscriminability’, understood as lacking evidence for the distinctness of things, is not suitable for defining this relation. Instead, we should say that a hallucination and a veridical perception involve the same phenomenal properties. This has further consequences for attempts to give necessary and sufficient conditions for the identity of phenomenal properties in terms of indiscriminability, and for considerations (...) about the phenomenal sorites.

It is argued that Husserl was an “externalist” in at least one sense. For it is argued that Husserl held that genuinely perceptual experiences—that is to say, experiences that are of some real object in the world—differ intrinsically, essentially and as a kind from any hallucinatory experiences. There is, therefore, no neutral “content” that such perceptual experiences share with hallucinations, differing from them only over whether some additional non-psychological condition holds or not. In short, it is argued that Husserl was (...) a “disjunctivist”. In addition, it is argued that Husserl held that the individual object of any experience, perceptual or hallucinatory, is essential to and partly constitutive of that experience. The argument focuses on three aspects of Husserl’s thought: his account of intentional objects, his notion of horizon, and his account of reality. (shrink)

This essay is a long one. It is not meant to be read in a single sitting. Its structure is as follows. In section I, I explicate perceptual anti-individualism. Section II centers on the two aspects of the representational content of perceptual states. Sections III and IV concern the nature of the empirical psychology of vision, and its bearing on the individuation of perceptual states. Section V shows how what is known from empirical psychology undermines disjunctivism and hence certain further (...) views that entail it, including naive realism. In Section VI, I raise a further point against disjunctivism. Section VII indicates how general reflection on perceptual perspective and epistemic ability supports the constraints from empirical psychology. It also explains how reflection on veridicality conditions, psychological explanation, and cognitive ability conspire to force recognition of the two kinds of representation mentioned in the preceding paragraph. In the Appendix, I criticize attempts to support disjunctivism. (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.

A natural starting point for theories of perceptual states is ordinary perception, in which a subject is successfully related to her mind-independent surroundings. Correspondingly, the simplest theory of perceptual states models all such states on perception. Typically, this simple, common-factor relational view of perceptual states has received a perfunctory dismissal on the grounds that hallucinations are nonperceptual. But I argue that the nonperceptual view of hallucinations has been accepted too quickly. I consider three observations thought to support the view, and (...) argue that all three are dealt with equally well by an alternative view, illusionism, on which hallucinations do involve perception. Since this is so, adopting a common-factor relational view of all perceptual states remains a tenable option. (shrink)

This book offers a provocative, clear and rigorously argued account of the nature of perception and its role in the production of knowledge. Walter Hopp argues that perceptual experiences do not have conceptual content, and that what makes them play a distinctive epistemic role is not the features which they share with beliefs, but something that in fact sets them radically apart. He explains that the reason-giving relation between experiences and beliefs is what Edmund Husserl called 'fulfilment' - in which (...) we find something to be as we think it to be. His book covers a wide range of central topics in contemporary philosophy of mind, epistemology and traditional phenomenology. It is essential reading for contemporary analytic philosophers of mind and phenomenologists alike. (shrink)

In the first section of this paper, after briefly arguing for the assumption that experiential content is propositional, I’ll distinguish three interpretations of the claim that experience has content (the Mild, Medium, and Spicy Content Views). In the second section, I’ll flesh out Naïve Realism in greater detail, and I’ll reconstruct what I take to be the main argument for its incompatibility with the Content Views. The third section will be devoted to evaluation of existing arguments for the Mild Content (...) View (the arguments from accuracy and appearing), and the development of what I take to be a stronger argument (the argument from belief generation). In the final section, I’ll identify a flaw in the argument for the incompatibility of Naïve Realism with the Content Views, which opens the door to a reconciliation. (shrink)

Husserl seems to have devoted roughly equal amounts of energy and pages to the description of perception, judgement, and imagination. By “description,” he meant the analysis of the traits and components of mental states or acts and their objects. As his views changed over the years about the nature of intentionality and philosophy, the descriptive psychology of the Logical Investigations (1900/01) gave way to descriptive programmes in which the objects of perception and of judgement were conceived of in terms of (...) a new, analytic framework; in particular Husserl lost interest in describing the things and processes in the real world that are the objects of perception and judgement and so too in describing their relations to these acts. His new analytic framework, particularly as it applies to perception, has been thoroughly expounded and discussed in the literature. My aim here is to expound Husserl's first descriptions of perception within the framework of the Investigations and to incorporate as far as possible his later descriptive results to the extent that these are separable from his later turn to idealism.
