What is the distinctively philosophical problem of perception? Here it is argued that it is the conflict between the nature of perceptual experience as it intuitively seems to us, and certain possibilities which are implicit in the very idea of experience: possibilities of illusion and to the world' which involves direct awareness of existing objects and their properties. But if one can have an experience of the same kind without the object being there -- a hallucination of an object -- (...) then it seems that perceptual experience cannot essentially be such a relation. This is the fundamentally philosophical problem of perception; the various philosophical theories of perception in the 20th and 21st centuries can be seen as responses to it. (shrink)

Intentionality may be dealt with in two different ways: either ontologically, as an ordinary relation to some extraordinary objects, or epistemologically, as an extraordinary relation to some ordinary objects. This paper endorses the epistemological view in order to provide a model of semiotic intentionality defined as the meaning-and-cognizing process that constitutes to power of the mind to be about something on the basis of a semiotic system. After a short introduction that presents the components of semiotic intentionality (viz. sign, act, (...) content, referent) along with their division into an intending and a fulfilling side (Sect. 1), the first main part of the paper analyzes semiotic intentionality at its primary level (a.k.a. 'concrete intentionality') as a real and subjective relation between meaning-intending and meaning-fulfilling acts grounded in the manipulation of some semiotic system (Sect. 2). Then, building on such concrete intentionality, the second main part of the paper analyzes semiotic intentionality at its secondary level (a.k.a. 'abstract intentionality') as an ideal and objective relation between intentional and fulfillment contents, which in turn: (i) proceed from an abstraction performed on the intending and fulfilling acts, respectively, and (ii) retroactively categorize the intending and fulfilling acts, respectively (Sect. 3). Finally, from this combination of an act-based conception of content with a presentationalist account of intentionality, the conclusion of this paper produces the intended model of semiotic intentionality in such a way that knowledge and truth are then respectively defined in it as the subjective correspondence between the two acts of concrete intentionality and as the objective correspondence between the two contents of abstract intentionality (Sect. 4).

Average-NPs, such as the one in the title of this paper, have been claimed to be ‘linguistically identical’ to any other definite-NPs but at the same time to be ‘semantically inconsistent’ with these other definite-NPs. To some this is an ironclad proof of the irrelevance of semantics to linguistics. We argue that both of the initial claims are wrong: average-NPs are not ‘linguistically identical’ to other definite-NPs but instead show a number of interesting divergences, and we provide a plausible semantic (...) account for them that is not ‘semantically inconsistent’ with the account afforded other definite-NPs but in fact blends quite nicely with one standard account of the semantics for NPs.

In the direct realist tradition of Reid and Austin, disjunctivism has joined its precursors inproudly trumpeting its allegiance with naïve realism. And the theory gains plausibility, par-ticularly as compared with adverbialism, if one considers a Wittgensteinian line of argumentregarding the use of sensation words. But ‘no common factor’ doctrines can be shown to beinconsistent with the naïve realism that has served as their main support. This does notmean that either disjunctivism or the Wittgensteinian perspective on language acquisitionthat informed it must (...) be false. It does indicate, however, that linguistic arguments againstprivate or internal meanings do not imply perceptual directness and that the espousal of direct realism—naïve or not—does not require adherence to disjunctivism.

Psychology, according to a standard dictionary definition, is the science of mind and behavior. For a major part of the twentieth century, (nonhuman) animal psychology was on a behavioristic track that explicitly denied the possibility of a science of animal mind. While many comparative psychologists remain wedded to behavioristic methods, they have more recently adopted a cognitive, information-processing approach that does not adhere to the strictures of stimulus-response explanations of animal behavior. Cognitive ethologists are typically willing to go much further (...) than comparative psychologists by adopting folk-psychological terms to explain the behavior of nonhuman animals. This different attitudes of many scientists presupposes a distinction between cognitive and mental state attributions that is not commonly articulated. This paper seeks to understand that distinction. (shrink)

Discourse containing the verb ‘feel’, almost without exception, purports to describe inner experience. Though this much is evident, the question remains what exactly is conveyed when we talk about what and how we feel? Does discourse containing the word ‘feel’ actually succeed in describing the content and phenomenology of inner experience? If so, how does it reflect the phenomenology and content of the experience it describes? Here I offer a linguistic analysis of ‘feels’ reports and argue that a subset of (...) ‘feels’ reports, when accurate, reflect the representational content of emotions, tactile experiences and bodily sensations. Because ‘feels’ reports may reflect the representational content of bodily experience, these types of report may be able to give us some insight into the structure of bodily experience. I argue that our descriptions of bodily experience, on the assumption that they are sometimes accurate, indicate that emotions and tactile experiences are experiences of bodily reactions to objects, whereas bodily sensations are partial descriptions of emotions and tactile experiences or other events of the body. At the end I address the concern that an adequate account of inner experience cannot be given in terms of an analysis of ordinary language. (shrink)

In this dissertation, I examine three philosophically important concepts that play a foundational role in developmental psychology: theory, representation, and belief. I describe different ways in which the concepts have been understood and present reasons why a developmental psychologist, or a philosopher attuned to cognitive development, should prefer one understanding of these concepts over another.

The possibilities are explored of considering nothing as the intended object of thoughts that are literally about the concept of nothing first, and thereby of nothing. Nothing, on the proposed analysis, turns out to be nothing other than the property of being an intendable object. There are propositions that look to be both true and to be about nothing in the sense of being about the concept and ultimate intended object of what is here formally defined and designated as N-nothing. (...) We have been thinking about it already in reading and understanding the meaning of this abstract. Nothing nothings, we shall assert in all seriousness and with a definite formally definable literal meaning. The concept of N-nothing in that sense is a concept with identity conditions like that of any entity, the difference being that the concept of N-nothing is a nonentity and nonexistent intended object.

Recent work in experimental psychology and neuroscience has revealed a rather surprising architecture for early (or preattentive) perceptual processes. This paper will describe some of the surprising features of that architecture, and how they bear on recent philosophical debates about the notion of phenomenal consciousness. I will argue that the common sense idea that states of phenomenal consciousness are states of a unitary kind cannot survive confrontation with the details of how our early perceptual processing works. In particular, that architecture (...) forces us to contemplate the prospect of phenomenal consciousness being sundered in two, with states that have phenomenal character making an appearance far before the arrival of anything one could call consciousness or awareness.

In this paper I shall defend a projectivist view of sensory experience. The case I shall focus on is that of color experience. Projectivism has recently been criticized by some authors who claim that it is unintelligible, or at least implausible, and that it makes a severe category mistake. I shall argue that despite some prima facie impressions of implausibility, projectivism can be made intelligible, and plausible, if its details are spelled out in a reasonable way. In addition, projectivism is (...) ubiquitous in human psychology, and certain cases of projection are reasonably viewed as making a category mistake. Viewed from this perspective, sensory projection is just one instance of projectivism, brought about by low-level perceptual processing. Whether sensory projection is one that makes a category mistake is not obvious. However, even if it does, this is perfectly compatible with the evolutionary advantage of sensation and perception.

When we perceive we are under the impression of being directly aware of concrete, mindindependent objects. We also consider perception as a basic, reliable source for acquiring beliefs and an effective means for coping with the environment. In the philosophical literature, this direct and basic character of perception is sometimes captured by saying that perception is openness to the world. Articulating, refining and vindicating as far as possible this commonsensical view of perception as openness to the world is the main (...) objective of this work. In order to make the metaphor of openness tractable in theoretical terms, I set up the dialectic in terms of a contrast between representationalism, which holds that perception represents things as being a certain way, and pure relationalism, which holds that perception can be openness to the world only by being a non-representational relation between a subject and objects in the world. The main thesis that I defend with several arguments in this work is that perception is both representational and relational. Indeed, it intelligibly relates us to the world in virtue of its representational content. In chapter one, I place perception in the broader context of intentional states. I articulate a view on which intentional states are directed toward their objects in virtue of having representational content, and show that prima facie the arguments for thinking that paradigmatic intentional states such as belief have content apply to perception too. I also explain why pure relationalists would reject the application of the content-model to perception. Chapter two is devoted to Charles Travis’s argument that perceptual experience does not have content. I counter his argument by offering a phenomenological account of perceptual constancy, and I show that content is necessary for capturing constancy in theoretical terms. Further, I argue that content helps us to better explain how the mind-independent nature of concrete objects is manifest in the phenomenology of perceptual experience. Chapter three concerns the question of how we should elucidate perceptual experience as openness to the world in the face of illusion and hallucination. I consider three possible approaches, and I argue that a view on which perceptual experience is both representational and relational can best make sense of the relevant phenomena. In the fourth chapter, I consider the debate on phenomenal character between representationalist and purely relationalist views in light of a distinction between particularity and generality. I show how representationalists are committed to there being an element of generality in perception, and how pure relationalists construe perception as wholly particular instead. I defend the representationalist view on the grounds that generality is necessary to make sense of the phenomenal and epistemic determinacy of perception. In the concluding remarks, I consider the question of whether my view can make room for the relationality of perception, and I argue again that only a distorted view of the metaphor of openness to the world could lead one to think that content and relationality are incompatible.

Theories of cognition and theories of social practices and institutions have often each separately acknowledged the relevance of the other; but seldom have there been consistent and sustained attempts to synthesize these two areas within one explanatory framework. This is precisely what my dissertation aims to remedy. I propose that certain recent developments and themes in philosophy of mind and cognitive science, when understood in the right way, can explain the emergence and dynamics of social practices and institutions. Likewise, the (...) view I construct explains how social practices and institutions shape the character of cognition of their constituent agents. Moreover, I explain both cognitive and social agency under the single explanatory framework provided by Dynamic Systems Theory. Drawing upon the phenomenological tradition, "embodied, "extended", "embedded", "enactive", and "ecological" approaches to cognition, as well as the conceptual resources of Dynamic Systems Theory, I construct a theory of agency that sees cognitive and social agents as far-from-equilibrium, open, recursively self-maintenant dynamic systems. Depending on the specifics of concrete circumstances, such systems, which I call "Dynamic Embodied Agents", may develop and possess emergent capacities for error-detection, flexible learning, normative behavior, representation, self-reflection, various modes of pattern-recognition, a temporal sense of self, and even moral responsibility. Some such systems are also sensitive to perceived social influences ; while reciprocally constituting and causally affecting them. (shrink)

This chapter probes the connections between the metaphysics of meaning and the investigation of human communication. It first argues that contemporary philosophy of mind has inherited most of its metaphysical questions from Brentano's puzzling definition of intentionality. Then it examines how intentionality came to occupy the forefront of pragmatics in three steps. By investigating speech acts, Austin and ordinary language philosophers pioneered the study of intentional actions performed by uttering sentences of natural languages. Based on his novel concept of speaker's (...) meaning and his inferential view of human communication as a cooperative and rational activity, Grice developed a three-tiered model of the meaning of utterances: the linguistic meaning of the uttered sentence; the explicit truth-conditional content of the utterance; the implicit content conveyed by the utterance. Finally, the new emerging truth-conditional trend in pragmatics urges that not only the implicit content conveyed by an utterance but its explicit content as well depends on the speaker's communicative intention.

Questions concerning the nature of representation and what representations are about have been a staple of Western philosophy since Aristotle. Recently, these same questions have begun to concern neuroscientists, who have developed new techniques and theories for understanding how the locus of neurobiological representation, the brain, operates. My dissertation draws on philosophy and neuroscience to develop a novel theory of representational content.

The problem of philosophical skepticism relates to the difficulty involved in underwriting the claim that we know anything of spatio-temporal reality. It is often claimed, in fact, that proper philosophical scrutiny reveals quite the opposite from what common sense suggests. Knowledge of external reality is thought to be even quite obviously denied to us as a result of the alleged fact that we all fail to know that certain skeptical scenarios do not obtain. A skeptical scenario is one in which (...) we have neurological occurrences just like any normal situation in which we actually perceive spatio-temporal objects, but where we are deceived in some sense as a result of the manipulation of our brains from some outside source. In this work I attempt to address the problem of philosophical skepticism by claiming that most of us are able to come to know plenty about external reality, since we can come to realize that a certain philosophical theory of perception is correct. The theory I have in mind is what I call a non-cognitive theory of perception. According to this view, perceptual experience is defined by continuous, sensitive behavioral interaction with spatio-temporal objects of the appropriate size, shape, hardness, speed, etc. Knowing that this theory of perception is correct is equivalent to knowing that we know plenty about external reality. This is ultimately because by knowing that a non-cognitive theory of perception is true, we know that any skeptical scenario must fail to obtain. The structure of the work proceeds by first discussing the significance of the problem of philosophical skepticism in some detail. Chapter 1 lays out how the problem does indeed forcefully arise if it is conceded that we fail to know that the skeptical scenarios fail to obtain. Chapter 2 develops the sort of view of our epistemological situation that falls out of accepting without qualification that the problem exists. Chapter 3 examines and criticizes certain popular responses to the skeptical problem. The main goal of these first three preliminary chapters is to indicate that once it is admitted that we fail to know that the skeptical scenarios fail to obtain, the problem of philosophical skepticism forcefully presents itself. Chapter 4, however, attacks the idea that we fail to know that the skeptical scenarios fail to obtain. In this chapter I argue that this idea is wedded to the position that a certain theory of perception is correct. The theory in question is what I call a conjunctive theory of veridical experience. According to this view, normal experience of spatio-temporal objects occurs when a subject has a certain perceptual experience, and that experience also happens to match up with and/or be satisfied by what is really the case. Only when a theory of this sort is assumed, I argue, is the claim that we fail to know that the skeptical scenarios fail to obtain found to be obvious. In chapter 5 I argue that, in fact, a non-cognitive theory, rather than a conjunctive theory, is the correct view to maintain. In the final chapter 6 I develop the epistemological position that falls out of accepting a non-cognitive theory. (shrink)

The main thesis of this paper is twofold. In the first half of the paper, (§§1-2), I argue that there are two notions of mental representation, which I call objective and subjective. In the second part (§§3-7), I argue that this casts familiar tracking theories of mental representation as incomplete: while it is clear how they might account for objective representation, they at least require supplementation to account for subjective representation.

Professor Foxall suggests the radical behaviorist language of contingencies is fine as far as it goes, and is quite suitable for matters of prediction and control. However, he argues that radical behaviorist language is extensional, and that it is necessary to formally incorporate the intentional idiom into the language of behavioral science to promote explanations and interpretations of behavior that are comprehensive in scope. Notwithstanding Professor Foxall's arguments, radical behaviorists hold that the circumstances identified by the use of the intentional (...) idiom are accommodated by the radical behaviorist language of contingencies, not only for prediction and control but also for explanations and interpretations. Of central importance is that individuals may have histories that lead them to generate descriptions of past and present behavior, as well as descriptions of prevailing circumstances that have caused that behavior or are likely to cause that behavior in the future. The resulting verbal behavior may then enter into contingencies influencing their behavior, although the extent to which it does so varies across individuals as a function of their histories. Overall, the way that the pragmatism of radical behaviorism conceives of the nature and contribution of covert events differs appreciably from the way Professor Foxall conceives of the nature and contribution of intentional phenomena.

What are the relations between preattentive feature-placing and states of perceptual awareness? For the purposes of this paper, states of "perceptual awareness" are confined to the simplest possible exemplars: states in which one is aware of some aspect of the appearance of something one perceives. Subjective contours are used as an example. Early visual processing seems to employ independent, high-bandwidth, preattentive feature "channels", followed by a selective process that directs selective attention. The mechanisms that yield subjective contours are found very (...) early in this processing. An experiment by Greg Davis and Jon Driver is described; it seems to show that multiple subjective figures can be coded in these preattentive, parallel stages of visual processing. I propose that some of these preattentive states might register the very same differences that, were one aware of them, would be phenomenal differences. Some arguments pro and con on this possibility are assessed. (shrink)

I argue for three central theses: ‘intuition’ is ambiguous, in material object metaphysics ‘intuition’ refers to pre-theoretical beliefs, and these pre-theoretical beliefs are generated by an innate physical reasoning system. I begin by outlining the relevant background discussions on the nature of intuitions and their role in philosophy to motivate the need for a more careful investigation of the meaning of ‘intuition’ and the role of intuitions in specific sub-disciplines of philosophy. In chapters one and two I argue that ‘intuition’ (...) is ambiguous between an inflationary and deflationary sense. In the inflationary sense, ‘intuition’ refers to a priori intellectual seemings with a special phenomenology, conceptual etiology, and modal content. In the deflationary sense, ‘intuition’ refers to beliefs or inclinations to believe. In chapter three I specifically examine the use of intuitions in material object metaphysics and conclude that in this sub-community ‘intuition’ is used in the deflationary sense to refer to pre-theoretical beliefs. Drawing from research on infant cognition, in the final chapter I argue that intuitions regarding material object metaphysics are those judgments that arise from an innate physical reasoning system. Based on this empirical observation, I argue that metaphysicians ought to give preference to abstract intuitions over intuitions regarding concrete cases because these abstract intuitions reflect the innate structure of our physical reasoning mechanisms.
