Direct and Indirect Perception

In this paper, I explore and examine different ways in which affectivity is related to perception within ecological psychology. I assess whether some of those ways compromise the realist and direct aspects of traditional ecological perception. I sustain that they don’t. Affectivity, at least in some cases, turns the perception of fine-grained affordances possible. For an engaged perceiver, affectivity is not optional.

Since the 1970s, Michael Turvey, Robert Shaw, and William Mace have worked on the formulation of a philosophically-sound and empirically-tractable version of James Gibson.

The sense of touch provides us knowledge of two kinds of events. Tactile sensation (T) makes us aware of events on or just below the skin; haptic perception (H) gives us knowledge of things outside the body with which we are in contact. This paper argues that T and H are distinct experiences, and not (as some have argued) different aspects of the same touch-experience. In other words, T ≠ H. Moreover, H does not supervene on T. Secondly: In T, (...) we are aware of immanent, phenomenal qualities; in H, we come to know of transcendent qualities in things that exist independently of ourselves. Finally: T is non-spatial; it is indexed by parts of the body, but not by position in space. H, by contrast, is spatial. This brings to mind Kant’s contention that things are presented as existing objectively when they are represented spatially. (shrink)

Amodal completion is usually characterized as the representation of those parts of the perceived object that we get no sensory stimulation from. In the case of the visual sense modality, for example, amodal completion is the representation of occluded parts of objects we see. I argue that relationalism about perception, the view that perceptual experience is constituted by the relation to the perceived object, cannot give a coherent account of amodal completion. The relationalist has two options: construe the perceptual relation (...) as the relation to the entire perceived object or as the relation to the unoccluded parts of the perceived object. I argue that neither of these options are viable. (shrink)

ABSTRACTWhen I see a tree through my window, that particular worldly tree is said to be ‘in’, ‘on’, or ‘before’ my mind. My ordinary visual link to it is ‘intentional’. How similar to this link are...

The Problem of Perception is a pervasive and traditional problem about our ordinary conception of perceptual experience. The problem is created by the phenomena of perceptual illusion and hallucination: if these kinds of error are possible, how can perceptual experience be what we ordinarily understand it to be: something that enables direct perception of the world? These possibilities of error challenge the intelligibility of our ordinary conception of perceptual experience; the major theories of experience are responses to this challenge.

Much attention has recently been paid to the idea, which I label ‘External World Acquaintance’ (EWA), that the phenomenal character of perceptual experience is partially constituted by external features. One motivation for EWA which has received relatively little discussion is its alleged ability to help deal with the ‘Explanatory Gap’ (e.g. Fish 2008, 2009, Langsam 2011, Allen 2016). I provide a reformulation of this general line of thought, which makes clearer how and when EWA could help to explain the specific (...) phenomenal nature of visual experience. In particular, I argue that by focusing on the different kinds of perceptual actions that are available in the case of visual spatial vs. colour perception, we get a natural explanation for why we should expect the specific nature of colour phenomenology to remain less readily intelligible than the specific nature of visual spatial phenomenology.

There are passages in Kant’s writings according to which empirical intuitions have to be (a) singular, (b) object-dependent, and (c) immediate. It has also been argued that empirical intuitions (d) are not truth-apt, and (e) need to provide the subject with a proof of the possibility of the cognized object. Having relied on one or another of the a-e constraints, the naïve realist readers of Kant have argued that it is not possible for empirical intuitions to be representations. Instead they (...) have argued for a relationalist reading of empirical intuitions in terms of an acquaintance relation between the subject and the intuited object. -/- For the sake of argument, I will grant the naïve realist reader of Kant that empirical intuitions should satisfy all the a-e constraints. Nevertheless, by incorporating these constraints, one by one, into a representationalist theory of empirical intuitions, I will show that not only doesn’t a naïve realist reading of empirical intuitions follow, but also that the naïve realist has hastily overlooked a range of perfectly representationalist readings of intuitions available to Kant and his representationalist allies. On the positive side, I will argue that there is an extra constraint on intuitions—i.e., that givenness does not require presence to consciousness—that directly goes against any naïve realist account of intuitions.

A short entry on social affordance. Social affordances are possibilities for social interaction or possibilities for action that are shaped by social practices and norms.

Theories of philosophy of perception are too simplifying. Direct realism and representationalism, for example, are philosophical theories of perception about the nature of the perceived object and its location. It is common sense to say that we directly perceive, through our senses, physical objects together with their properties. However, if perceptual experience is representational, it only appears that we directly perceive the represented physical objects. Despite psychological studies concerning the role of memory in perception, what these two philosophical theories do (...) not explicate are the continuity of the external describable object and the role of memory in perceiving the continuity, difference, break or ending. Using empirical evidence of particular cases and the hypothetico-deductive model, this research article analyses how one is able to perceive the continuity of same things. The early stages of perceptual process are not sufficient for the perception of continuity. Empirical evidence of memory disorders shows that persons with a memory disorder do not perceive the same thing or the familiar place they previously saw and now experience or remember what they are thinking about, even if the object, the place or the person has remained the same. I will argue that the perception of continuity requires memory. In fact, observation indicates how the memory runs at the same time, when the object is seen over time. This fact implies the memory system’s essential role for perceiving the continuity of the same things. (shrink)

Visual experiences seem to exhibit phenomenological particularity: when you look at some object, it – that particular object – looks some way to you. But experiences exhibit generality too: when you look at a distinct but qualitatively identical object, things seem the same to you as they did in seeing the first object. Naïve realist accounts of visual experience have often been thought to have a problem with each of these observations. It has been claimed that naïve realist views cannot (...) account for the generality of visual experiences, and that the naïve realist explanation of particularity has unacceptable implications for self- knowledge: the knowledge we have of the character of our own experiences. We argue in this paper that neither claim is correct: naïve realism can explain the generality of experiences, and the naïve realist explanation of particularity raises no problems for our self-knowledge.

In this paper I will try to outline a Metaphysics of Perception that takes for granted one of the central thesis of the metaphysical doctrine called Indirect Realism. Firstly, I will introduce the central thesis of Indirect Realism and then a special version of the Causal Theory of Perception that modifies in some fundamental respect one of the most influential version of Causal Theory of Perception designed by William Child.

In this paper, I have outlined an original Metaphysics of Perception which takes into consideration some of the most common views about perception in the contemporary debate. Then I will look at the consequences of this metaphysics about our perception of others and what we know about them. In the third section, I suggest how to make sense of certain neuroscientific discoveries about social perception and social cognition. In the conclusion, I recap what has been done to say that others (...) are what we can know after all. (shrink)

Naive realism is a widely debated topic in the philosophy of the mind. In this article I will review the theses of naive realism through the works of one of the most influential philosophers who supported and developed them, Michael Martin. Once the reasons why naive realism should be supported are discussed, I will propose an empirical argument to show that naive realism and the most basic scientific knowledge of perceptive processes are contradictory.

What would be an adequate theory of social understanding? In the last decade, the philosophical debate has focused on Theory Theory, Simulation Theory and Interaction Theory as the three possible candidates. In the following, we look carefully at each of these and describe its main advantages and disadvantages. Based on this critical analysis, we formulate the need for a new account of social understanding. We propose the Person Model Theory as an independent new account which has greater explanatory power compared (...) to the existing theories. (shrink)

This thesis is a collection of five self-standing articles dealing with different issues relating to representationalism and relationalism in contemporary philosophy of perception and contemporary philosophy of memory. The main goal is to motivate a hybrid approach, where insights from representationalism and relationalism are reconciled, to current debates in both domains. The thesis is divided in two parts. Part I, which deals with perception, starts by seeking alternative relational views of perception by relying on ideas from classical pragmatism. These attempts (...) further result in the development of a hybrid theory of perception, grounded on the pragmatist theory of perception offered by Charles Peirce, that is more sympathetic to “austere” versions of relationalism. Part II, which deals with memory, starts by exploring the prospects of representationalism and relationalism to account for the objects of memory and the objects of episodic hypothetical thought. Relational accounts are further explored in this context for, despite their historical importance, they have been unpopular recently due to the difficulty they face in dealing with memory errors. Finally, as a positive proposal, I offer a hybrid theory of memory that is influenced by hybrid theories of perception. Besides calling the attention of philosophers of memory to the importance of taking relationalism seriously, this hybrid theory provides a novel theoretical framework for contemporary philosophers of memory.

Experimental philosophy’s much-discussed ‘restrictionist’ program seeks to delineate the extent to which philosophers may legitimately rely on intuitions about possible cases. The present paper shows that this program can be (i) put to the service of diagnostic problem-resolution (in the wake of J.L. Austin) and (ii) pursued by constructing and experimentally testing psycholinguistic explanations of intuitions which expose their lack of evidentiary value: The paper develops a psycholinguistic explanation of paradoxical intuitions that are prompted by verbal case-descriptions, and presents two (...) experiments that support the explanation. This debunking explanation helps resolve philosophical paradoxes about perception (known as ‘arguments from hallucination’). (shrink)

If we acknowledge that a perceptual experience’s sensory phenomenology is not inherently representational, we face a puzzle. On the one hand, sensory phenomenology must play an intimate role in the perception of ordinary physical objects; but on the other hand, our experiences’ purely sensory element rarely captures our attention. I maintain that neither indirect realism nor the dual component theory provides a satisfactory solution to this puzzle: indirect realism is inconsistent with the fact that sensory phenomenology typically goes unnoticed by (...) perceivers; while, the dual component theory cannot do justice to the important role that sensory phenomenology plays in our perceptual awareness of physical objects. I argue that in order to avoid the difficulties with each of the standard alternatives, we must characterize sensory phenomenology as functioning in the way that linguistic symbols function in thought.

In seeing a tilted penny, we are experientially aware of both its circularity and another shape, which I dub ‘β-ellipticality’. Some claim that our experiential awareness of the intrinsic shapes/sizes of everyday objects depends upon our experiential awareness of β-shapes/β-sizes. In contrast, I maintain that β-property experiences are the result of what Richard Wollheim calls ‘seeing-in’, but run in reverse: instead of seeing a three-dimensional object in a flat surface, we see a flat surface in a three-dimensional object. Using this (...) new account, I re-examine the phenomenological directness of visual experience and undermine an argument for skepticism about β-property experiences. (shrink)

The question of what we immediately perceive from the first-person point of view has been an issue of philosophizing since the beginning of Western philosophy. However, many philosophers have not considered all theoretical and practical consequences concerning identity and causation in perceptual experience between a perceiver and the external world. Despite their meritorious studies, philosophers have failed to completely understand how the causal series of events affects what we immediately experience. Using facts relating to perceivers, logical reasoning, introspection, and philosophical (...) theories, the aim of this research is to show that objects of sense have been contradictorily and confusedly associated with several objects in philosophy of perception. The research problem is that of whether the entity external to a perceiver is identical to the immediate object of perceptual experience. The research starts from the basic beliefs that things appear in experience and that there is causality in perceptual experience. After presenting philosophical theories of perception, the concept ‘sense-datum’, a characterization of ‘perception’, and basic arguments for perceiving the inner private sense-datum, the study examines Bertrand Russell’s and G. E Moore’s arguments for a claim that we always perceive mind-internal sense-data. This claim is problematic if ‘sense-datum’ is considered as being under the category of substance. Nonetheless, evidence for a claim in direct realism and eliminative materialism that the immediate object of perception is an external entity leads to circularity and identity problems. Finally, by means of a demonstration based on understanding and facts in perceivers and perceptual phenomena, the research concludes that the external entity is not identical to the immediate object of perceptual experience. Perceptual experience does not directly reach the external world, and the objects of sense are not independent of the perceiver. (shrink)

In this paper, I respond to Millar’s recent criticism of naïve realism. Millar provides several arguments for the thesis that there are powerful phenomenological grounds for preferring the content view to naïve realism. I intend to show that Millar’s arguments are not convincing.

Object files are mental representations that enable perceptual systems to keep track of objects as numerically the same. How is their reference fixed? A prominent approach, championed by Zenon Pylyshyn and John Campbell, makes room for a non-satisfactional use of properties to fix reference. This maneuver has enabled them to reconcile a singularist view of reference with the intuition that properties must play a role in reference fixing. This paper examines Campbell’s influential defense of this strategy. After criticizing it, a (...) new approach is sketched. The alternative view introduces representational contents to explain perceptual individuation. After arguing that those contents are not satisfactional, it is concluded that there is room for a third view of reference fixing that does not fit into the singularist/descriptivist dichotomy. (shrink)

Naïve realism, often overlooked among philosophical theories of perception, has in recent years attracted a surge of interest. Broadly speaking, the central commitment of naïve realism is that mind-independent objects are essential to the fundamental analysis of perceptual experience. Since the claims of naïve realism concern the essential metaphysical structure of conscious perception, its truth or falsity is of central importance to a wide range of topics, including the explanation of semantic reference and representational content, the nature of phenomenal consciousness, (...) and the basis of perceptual justification and knowledge. One of the greatest difficulties surrounding discussions of naïve realism, however, has been lack of clarity concerning exactly what affirming or denying it entails. In particular, it is sometimes unclear how naïve realism is related to the claim that perceptual experience is in some sense direct or unmediated, and also to what extent the view is compatible with another widely discussed thesis in the philosophy of perception, the claim that perceptual experiences are states with representational content. In this essay, I discuss how recent work on these issues helps to clarify both the central commitments of naïve realism, as well as its relation to representationalist theories of perception. Along the way, I will attempt to shed light on the different ways in which each approach tries to address the various theoretical challenges facing a philosophical theory of perception, and also to assess the prospects for views that attempts to combine features of each approach.

Phenomenal particularism is the view that particular external objects are sometimes part of the phenomenal character of perceptual experience. It is a central part of naïve realist or relational views of perception. We consider a series of recent objections to phenomenal particularism and argue that naïve realism has the resources to block them. In particular, we show that these objections rest on assumptions about the nature of phenomenal character that the naïve realist will reject, and that they ignore the full (...) resources that naïve realism has to offer in explaining phenomenal character.

It is often assumed that when we see common opaque objects in standard light this is in virtue of seeing their facing surfaces. Here I argue that we should reject that claim. Either we don't see objects' facing surfaces, or—if we hold on to the claim that we do see such things—it is at least not in virtue of seeing them that we see common opaque objects. I end by showing how this conclusion squares both with our intuitions and with (...) the facts of vision science. (shrink)

In his dispute with Malebranche about the nature of ideas, Arnauld endorses a form of direct realism. This appears to conflict with views put forward by Arnauld and his collaborators in the Port-Royal Grammar and Logic where ideas are treated as objects in the mind. This tension can be resolved by a careful examination of Arnauld's remarks on the semantics of ‘perception’ and ‘idea’ in light of the Port-Royal theory of language. This examination leads to the conclusion that Arnauld's ideas (...) really are objects in the mind, and not perceptual acts as many commentators hold. What Arnauld denies is that these mental objects are really distinct from the external objects they represent. Instead, Arnauld holds that, by the act of conception, the external objects themselves—not copies—come to be present in the mind and are therefore called ‘ideas’. (shrink)

This paper surveys selected (though arguably representative) versions of metaphysical and epistemological disjunctivism. Although they share a common logical structure, it is hard to find a further common denominator among them. Two main conclusions are: (1) a specific standpoint on the nature of perceptual relation is not such a common denominator, which means that it is very unlikely that all of these views could be refuted with a single objection; (2) contrary to what its name suggests, disjunctivism can be correctly (...) expressed without the employment of disjunction.

In this paper, I discuss Noë’s enactive account of our perceptual encounter with the intrinsic properties of the surrounding objects. First, I argue that this view falls into a dilemma in which either we are left without a satisfactory explanation of this encounter or, in order to keep Noë’s view, we must abandon our ordinary intuitions about the ontological status of the intrinsic properties of objects. Then, I show that, strikingly, there is a suggestive unofficial strand running in Noë that (...) avoids this dilemma. Finally, I argue this unofficial thread leads to a view about the perspectival character of perceptual experience and the place of sensorimotor understanding in perceptual content that is to be preferred over Noë’s official view about these issues.

In An Inquiry into the Human Mind and in Essays on Intellectual Powers, Thomas Reid discusses what kinds of things perceivers are related to in perception. Are these things qualities of bodies, the bodies themselves, or both? This question places him in a long tradition of philosophers concerned with understanding how human perception works in connecting us with the external world. It is still an open question in the philosophy of perception whether the human perceptual system is providing us with (...) representations as of bodies, or only as of their properties. My project in this article is to explain how, on Reid's view, we can have perceptual representations as of bodies. This, in turn, enables him to argue that we have a robust understanding of the world around us, an understanding that would be missing if our perceptual system only supplied us with representations as of free-floating properties of bodies.

In this brief discussion, we explicate and evaluate Heyes and colleagues’ deflationary approach to interpreting apparent evidence of domain-specific processes for social percep- tion. We argue that the deflationary approach sheds important light on how functionally specific processes in social perception can be subserved at least in part by domain-general processes. On the other hand, we also argue that the fruitfulness of this approach has been unnecessarily hampered by a contrastive conception of the relationship between domain- general and domain-specific processes. (...) As an alternative, we propose a complementary conception: the identification of domain-general processes that are engaged in instances of social perception can play a positive, structuring role by adding additional constraints to be accounted for in modelling the domain-specific processes that are also involved in such instances.

Current orthodoxy in the philosophy of perception views indirect realism as misguided, wrongheaded or simply outdated. The reasons for its pariah status are variegated. Although it is surely not unreasonable to speculate that philosophical fashion is one factor that contributes to this situation, there are also solid philosophical arguments which put pressure on the indirect realist position. In this paper, I will discuss one such main objection and show how the indirect realist can face it. The upshot will be a (...) defence of a new structural account of indirect realism which is immune to a number of objections that have been traditionally levelled at such theories of perceptual consciousness.

Questions concerning perception are as old as the field of philosophy itself. Using the first-person perspective as a starting point and philosophical documents, the study examines the relationship between knowledge and perception. The problem is that of how one knows what one immediately perceives. The everyday belief that an object of perception is known to be a material object on grounds of perception is demonstrated as unreliable. It is possible that directly perceived sensible particulars are mind-internal images, shapes, sounds, touches, (...) tastes and smells. According to the appearance/reality distinction, the world of perception is the apparent realm, not the real external world. However, the distinction does not necessarily refute the existence of the external world. We have a causal connection with the external world via mind-internal particulars, and therefore we have indirect knowledge about the external world through perceptual experience. The research especially concerns the reasons for George Berkeley’s claim that material things are mind-dependent ideas that really are perceived. The necessity of a perceiver’s own qualities for perceptual experience, such as mind, consciousness, and the brain, supports the causal theory of perception. Finally, it is asked why mind-internal entities are present when perceiving an object. Perception would not directly discern material objects without the presupposition of extra entities located between a perceiver and the external world. Nevertheless, the results show that perception is not sufficient to know what a perceptual object is, and that the existence of appearances is necessary to know that the external world is being perceived. However, the impossibility of matter does not follow from Berkeley’s theory. The main result of the research is that singular knowledge claims about the external world never refer directly and immediately to the objects of the external world. A perceiver’s own qualities affect how perceptual objects appear in a perceptual situation. (shrink)

I will use three simple arguments to refute the thesis that I appear to directly perceive a mind-independent material object. The theses I will use are similar to the time-gap argument and the argument from the relativity of perception. The visual object of imagination and the object of experience are in the same place. They also share common qualities such as the content, subjectivity, change in virtue of conditions of observers, and the like. This leads to the conclusion that both (...) a tree-image and a tree-experience are distinct from a material tree. Perception of an object is caused by human nature, the senses and consciousness, and mind may prevent the direct perception of the external world. The strongest objection against that consequence is that there is no extra entity called sense-datum or appearance between a subject-in-itself and a real external thing-in-itself. That is, we see books, not book-images. The possible reply would be that a person sees no mental pictures except that which they see via pictures. (shrink)

Resumen: En este ensayo discuto la crítica de John Campbell a la tesis de la inescrutabilidad de la referencia de Quine. Primero defiendo que los argumentos de Campbell no dan en el blanco, pues él pasa por alto la conexión que Quine traza entre referencia, cuantificación, y ontología. Luego discuto otra línea de argumentación contra la inescrutabilidad que invoca la concepción relacional de la atención de Campbell. Finalmente, sugiero que esta línea –aunque insuficiente y necesitada de complemento– pone de manifiesto (...) que tras las posturas de ambos autores sobre la referencia hay importantes ideales filosóficos hacia los cuales debe dirigirse la discusión.

A longstanding philosophical tradition holds that the primary objects of hearing are sounds rather than sound sources. In this case, we hear sound sources by—or in virtue of—hearing their sounds. This paper argues that, on the contrary, we have good reason to believe that the primary objects of hearing are sound sources, and that the relationship between a sound and its source is much like the relationship between a color and its bearer. Just as we see objects in seeing their (...) colors, so we hear sound sources in hearing their sounds. (shrink)

I consider a new, non-disjunctive strategy for ‘relational’ or ‘naïve realist’ theories to respond to arguments from ‘perfect’ (causally matching) hallucinations. The strategy, in a nutshell, is to treat such hypothetical cases as instances of perception rather than hallucination. After clarifying the form and dialectic of such arguments, I consider three objections to the strategy. I provide answers to the first two objections but concede that the third — based on the possibility of ‘chaotic’ (uncaused) perfect hallucinations — cannot obviously (...) be dealt with by the proposed strategy. However, such ‘chaotic’ scenarios are also problematic for standard representational accounts of experience. Thus I conclude that perfect hallucinations pose no more of a threat to the relational theory than to its main representational rival. (shrink)

According to proponents of relational direct realism, veridical perceptual experiences are irreducibly relational mental states that include as constituents perceived physical objects or intrinsic aspects of them. One consequence of the theory is the rejection of the causal theory of perception. This paper defends the relational theory against several objections recently developed by Paul Coates. He argues that the required experiential relation is incoherent and unmotivated. The argument that it is incoherent commits a fallacy. In reply to the argument that (...) it is unmotivated, I suggest that the relational theorist's appeal to transparency provides sufficient motive and, when properly clarified, defeasibly justifies the theory as well. Coates also argues that rejection of the causal theory leaves relational theorists without any way of determining which object is perceived or of accommodating our scientific understanding of perceptual experiences as causally dependent on physical objects. I reply that relational theorists are able to provide the required explanations and discuss how the relational theory is consistent with this scientific understanding of perceptual experience.

In this focused and carefully argued book, Bill Brewer develops and defends the Object View (OV), a version of direct realism. Brewer appropriates for his foundational concept what he considers to be a key insight of the early modern tradition: perceptual experience is an irreducibly relational act of direct acquaintance, the direct object of which constitutes the fundamental nature of experience. While many of the early moderns held—partly as a consequence of the arguments from hallucination and illusion—that the direct objects (...) were always mind-dependent, the core claim of OV is that the direct objects of non-hallucinatory perceptual experiences are mind-independent physical objects. After some stage setting (chapter 1), Brewer argues against competing theories of perception (chapters 2–4) and then defends OV against the arguments from illusion and hallucination, addresses the role of perceptual experience in grounding empirical knowledge, and discusses the way in which the objects of awareness acquire status as mind-independent within an individual’s experience (chapters 5–7).

This paper presents an argument against A D Smith’s Direct Realist theory of perception, which attempts to defend Direct Realism against the argument from illusion by appealing to conscious perceptual states that are structured by the perceptual constancies. Smith’s contention is that the immediate objects of perceptual awareness are characterised by these constancies, which removes any difficulty there may be in identifying them with the external, or normal, objects of awareness. It is here argued that Smith’s theory does not provide (...) an adequate defence of Direct Realism because it does not adequately deal with the difficulties posed by the possibility of perceptual illusion. It is argued that there remain possible illusory experiences where the immediate objects of awareness, which in Smith’s account are those characterised by perceptual constancies, cannot be identified with the external objects of awareness, contrary to Direct Realism. A further argument is offered to extend this conclusion to all non-illusory cases, by adapting an argument of Smith’s own for the generalising step of the Argument from Illusion. The result is that Smith’s theory does not provide an adequate Direct Realist account of the possibility of perceptual illusion. (shrink)

Based on the notion of a trope, this paper gives a novel analysis of identificational sentences such as 'this is Mary','this is a beautiful woman', 'this looks like Mary', or 'this is the same lump of clay, but not the same statue as that'.

We seem to directly perceive external things. But can we? According to the time‐lag argument, we cannot. What we directly perceive happens now. There is a time‐lag between our perceptions and the external things we seem to directly perceive; these external things happen in the past; thus, what we directly perceive must be something else, for example, sense‐data, and we can only at best indirectly perceive other things. This paper examines the time‐lag argument given contemporary metaphysics. I argue that this (...) argument is not as compelling as it may initially seem. First, it denies that what we directly perceive can ever be what it seems to be; second, it conflicts with the current physical conception of time, relativity theory. This latter point leads to a more general one: the argument's force depends on a particular metaphysical conception on time, presentism, which is controversial in contemporary metaphysics of time. Given the alternative conception, eternalism, the argument is much less compelling. The overall argument of this paper, then, is that, if one wishes to hold that we directly perceive external things, we should subscribe to the latter view of time, i.e., eternalism. (shrink)

There are issues in Reid scholarship as well as the primary texts that seem to suggest that Reid is not a direct realist about visual perception. In this paper, I examine two key issues ? colour perception and visible figure ? and attempt to defend the direct realism of Reid's theory through an interpretation of ?directness? as well as what Reid calls ?acquired perception?, which is ?mediate? in that it requires prior perception of signs, but nonetheless constitutes direct perception.

Abstract The debate in the philosophy of perception between direct realists and representationalists should influence the debate in epistemology between internalists and externalists about justification. If direct realists are correct, there are more consciously accessible justifiers for internalists to exploit than externalists think. Internalists can retain their distinctive internalist identity while accepting this widened conception of internalistic justification: even if they welcome the possibility of cognitive access to external facts, their position is still quite distinct from the typical externalist position. (...) To demonstrate this, Alvin Goldman’s critique of internalism is shown to ignore important lessons from the case for direct realism about perception. In particular, it unjustifiably assumes that internalism entails that only facts simultaneous with the justification of a belief can justify the belief. Goldman’s definition of a “justifier” is also inconsistent with the overall guidance conception of epistemology he takes for granted in his critique of internalism.

Abstract The paper considers the success of enactive realism about perception; the theory that perceivers gain direct access to the mind-independent physical world through their exercise of sensorimotor skills and understanding. I argue that while it is plausible that the possession of some forms of knowledge, conceptual or practical, may enable perceptual contact with the environment, the role of sensorimotor mastery is not as pervasive as the enactive realist proposes. Non-veridical perception, furthermore, cannot be captured adequately by enactivist resources under (...) a disjunctivist framework. (shrink)
