The fact that you see some particular object seems to be due to the causal relation between your visual experience and that object, rather than to your experiences’ phenomenal character. On the one hand, whenever some phenomenal element of your experience stands in the right sort of causal relation to some object, your experience presents that object (your experience’s phenomenology doesn’t need to match that object). On the other hand, you can’t have a perceptual experience that presents some object unless (...) you stand in the right sort of causal relation to that object (no matter how closely your experience’s phenomenology matches some object). According to the continuity thesis, property perception is similar to object perception in these two respects. A standard reason to reject the continuity thesis is the assumption that the environmental properties that a perceptual experience presents are determined by its phenomenal properties (which are not determined by the environmental properties that cause the experience). I maintain that the continuity thesis is false but for a different reason: perceptual experiences present both objects and properties via manners of presentation; but, whereas perceptual manners of presentation for objects are purely relational, perceptual manners of presentation for properties are satisfactional.

I respond to three arguments aimed at establishing that natural kind properties — a kind of high-level properties — occur in the experiential content of visual perceptual experience: the argument from phenomenal difference, the argument from mandatory seeing, and the argument from associative agnosia. I conclude with a simple argument against the view that natural kind properties occur in the experiential content of visual experience.

The advocates of moral perception claim that we can literally perceive moral properties such as goodness and badness. One of the objections to the thesis of moral perception is that since we are not able to causally interact with moral properties and these properties are causally inert, thus they do not fall into the scope of our perception. In reply, the advocates propose different solutions: 1) moral properties supervene on natural properties, 2) moral properties (...) are secondary natural properties, and 3) moral properties are non-secondary natural properties. Each of these proposals aims to attack a different premise of the objection. In this paper, I am going to propose the thesis that assuming that moral properties are grounded in natural properties, Wilsonian grounding can be a new reply to this objection. I will try to explain how Alastair Wilson’s account of grounding, in addition to a grounding thesis about the relation between moral and natural properties, can prevent accidence without setting moral properties aside from perceptual scope.

Whether we perceive high-level properties is presently a source of controversy. A promising test case for whether we do is aesthetic perception. Aesthetic properties are distinct from low-level properties, like shape and colour. Moreover, some of them, e.g. being serene and being handsome, are properties we appear to perceive. Aesthetic perception also shares a similarity with gestalt effects, e.g. seeing-as, in that aesthetic properties, like gestalt phenomena, appear to ‘emerge’ from low-level properties. Gestalts effects, (...) of course, are widely observed, which raises the question: do gestalt effects make it plausible that we perceive high-level aesthetic properties? Contra Stokes, this paper argues that they don’t. This is interesting in its own right, but it also points to a more general lesson, namely we should resist the temptation to appeal to gestalt effects to argue for high-level perception. (shrink)

Thomas Reid famously claimed that our perceptual experiences reveal what primary qualities are in themselves, while providing us with only an obscure notion of secondary qualities. I maintain that this claim is largely correct and that, consequently, any adequate theory of perception must explain the fact that perceptual experiences provide significantly less insight into the nature of secondary qualities than into the nature of primary qualities. I maintain that neither naïve realism nor the standard Russellian variety of the content view (...) can provide a satisfying explanation; instead, in order to provide a satisfying explanation, we must posit that perceptual experiences represent properties via Fregean modes of presentation. Further, I maintain that we must depart from the standard Fregean variety of the content view in two important respects. First, the relevant modes of presentation must be characterized without appealing to causal relations between perceptual experiences and perceived properties; and second, we must posit that primary and secondary qualities are represented via modes of presentation of different kinds. The resulting view is that primary qualities are represented via perceptual modes of presentation analogous to highly detailed descriptions, while secondary qualities are represented via perceptual modes of presentation analogous to impoverished descriptions.

Perception of time is susceptible to distortions; among other factors, it has been suggested that the perceived duration of a stimulus is affected by the observer’s expectations. It has been hypothesized that the duration of an oddball stimulus is overestimated because it is unexpected, whereas repeated stimuli have a shorter perceived duration because they are expected. However, recent findings suggest instead that fulfilled expectations about a stimulus elicit an increase in perceived duration, and that the oddball effect (...) occurs because the oddball is a target stimulus, not because it is unexpected. Therefore, it has been suggested that top-down attention is sometimes sufficient to explain this effect, and sometimes only necessary, with an additional contribution from saliency. However, how the expectedness of a target stimulus and its salient features affect its perceived duration is still an open question. In the present study, participants’ expectations about and the saliency of target stimuli were orthogonally manipulated with stimuli presented on a short (Experiment 1) or long (Experiment 2) temporal scale. Four repetitive standard stimuli preceded each target stimulus in a task in which participants judged whether the target was longer or shorter in duration than the standards. Engagement of top-down attention to target stimuli increased their perceived duration to the same extent irrespective of their expectedness. A small but significant additional contribution to this effect from the saliency of target stimuli was dependent on the temporal scale of stimulus presentation. In Experiment 1, saliency only significantly increased perceived duration in the case of expected target stimuli. In contrast, in Experiment 2, saliency exerted a significant effect on the overestimation elicited by unexpected target stimuli, but the contribution of this variable was eliminated in the case of expected target stimuli. These findings point to top-down attention as the primary cognitive mechanism underlying the perceptual extraction and processing of task-relevant information, which may be strongly correlated with perceived duration. Furthermore, the scalar properties of timing were observed, favoring the pacemaker-accumulator model of timing as the underlying timing mechanism. (shrink)

The topic of this paper is the perception of properties. It is argued that the perception of properties allows for a distinction between the sense of the identity and the sense of the qualitative nature of a property. So, for example, we might perceive a property as being identical over time even though it is presented as more and more determinate. Thus, you might see an object first as red and then as crimson red. In this case, the (...) property is perceived as identical over time, even though the sense of the qualitative nature (the redness, the crimson redness) of the property is changing. The distinction between the sense of identity and the sense of quality is explicated in terms of perceiving a particular property, a trope, and perceiving it as an instance of a universal. It is subsequently argued that the perceived tropes cannot constitute the phenomenal character of the perceptual experience. (shrink)

Hermann von Helmholtz’s work on perceptual science had a fundamental impact on Neo-Kantian movements in the late nineteenth century, and his influence continues to be felt in psychology and analytic philosophy of perception. As is widely acknowledged, Helmholtz denied that we can perceive mind-independent properties of external objects, a view I label Ignorance. Given his commitment to Ignorance, Helmholtz might seem to be committed to a subjectivism according to which we only perceive properties of our own representations. Against (...) this, I argue that for Helmholtz, the properties we perceive are not monadic properties of either the subject or the object. Rather, Helmholtz endorsed a relationalism about the properties we perceive: the properties of objects we perceive are all relational properties. I then suggest that once we take into account oft-neglected terminological distinctions in Helmholtz’s corpus, we are better able to make sense of his commitment to relationalism. (shrink)

There are two very different ways of thinking about perception. According to the first one, perception is representational: it represents the world as being a certain way. According to the second, perception is a genuine relation between the perceiver and a token object. These two views are thought to be incompatible. My aim is to work out the least problematic version of the representational view of perception that preserves the most important considerations in favor of the relational view. According to (...) this version of representationalism, the properties represented in perception are tropes—abstract particulars that are logically incapable of being present in two distinct individuals at the same time. I call this view ‘trope representationalism’. (shrink)

It has been argued recently that perception is indeterminate. But there are more than one ways of spelling out what this means. The standard line is that perceptual states attribute different probabilities to different propositions. I provide an alternative to this view, where it is not the attitude, but the content of perceptual states that is indeterminate, inasmuch as it consists of the representation of determinable properties. This view does justice to the more general claim that perception is indeterminate (...) without appealing to probability either in the attitude or in the content. (shrink)

This paper argues for a realist position in the metaphysics of aesthetic properties. Realist positions about aesthetic properties are few and far between, though sometimes developed by analogy to realism about colours. By contrast, my position is based on a disanalogy between aesthetic properties and colours. Unlike colours, aesthetic properties are perceived as relatively unsteady properties: as powers that objects have to cause a certain experience in the observer. Following on from this observation, I (...) develop a realist account of aesthetic properties as causally efficient powers, analogous to properties like fragility or poisonousness. To show how such a view can be made ontologically respectable, I draw on recent ‘dispositionalist’ accounts of powers in philosophical metaphysics. I then offer two arguments in favour of this view. First, the view matches the phenomenology of aesthetic judgement. Second, the view offers an explanation of how it is that critics can demand agreement with their aesthetic judgements. (shrink)

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.

Color subjectivists claim that, despite appearances to the contrary, the world external to the mind is colorless. However, in giving an account of color perception, subjectivists about the nature of perceived color must address the nature of perceived spatial location as well. The argument here will be that subjectivists’ problems with coordinating the metaphysics of perceived color and perceived location render color perception implausibly mysterious. Consequently, some version of color realism, the view that colors are (physical, (...) dispositional, functional, sui generis, or some other) properties of physical objects, is correct. (shrink)

I aim to give a new account of picture perception: of the way our visual system functions when we see something in a picture. My argument relies on the functional distinction between the ventral and dorsal visual subsystems. I propose that it is constitutive of picture perception that our ventral subsystem attributes properties to the depicted scene, whereas our dorsal subsystem attributes properties to the picture surface. This duality elucidates Richard Wollheim’s concept of the “twofoldness” of our experience (...) of pictures: the “visual awareness not only of what is represented but also of the surface qualities of the representation.” I argue for the following four claims: (a) the depicted scene is represented by ventral perception, (b) the depicted scene is not represented by dorsal perception, (c) the picture surface is represented by dorsal perception, and (d) the picture surface is not necessarily represented by ventral perception.

Recently, a number of philosophers have argued that property illusions—cases in which we perceive a property, but that property is not the property it seems to us to be in virtue of our perceptual experience—and veridical illusions—cases in which we veridically perceive an object’s properties, but our experience of some specific property is nonetheless unsuccessful or illusory—can occur. I defend the contrary view. First, I maintain that there are compelling reasons to conclude that property illusions and veridical illusions can’t (...) occur; and second, I maintain that the considerations supporting the possibility of such cases are uncompelling.

Molyneux’s question asks whether a person born blind who has learned to identify shapes by touch could, if suddenly granted sight, immediately identify shapes visually. This question has often been used to structure discussions of whether there is a “rational connection” between sight and touch—whether it is possible to rationally doubt whether the same shape properties are both seen and felt. I distinguish two questions under this general heading. The first concerns, roughly, whether the visual and haptic perception of (...) shape is rationally connected in normally sighted perceivers. The second concerns, roughly, whether the visual and haptic perception of shape is rationally connected in all possible perceivers. I argue that real-world implementations of Molyneux’s question are irrelevant to the first question, but potentially relevant to the second. However, I also argue that the second question does not have the philosophical significance it is sometimes claimed to have. In particular, it cannot be used to adjudicate debates about whether the phenomenal character of perceptual experience is primarily determined “externally” by the worldly properties we perceive, or “internally” by physiological or functional properties of our brains.

The modifier effect is the reduction in perceived likelihood of a generic property sentence, when the head noun is modified. We investigated the prediction that the modifier effect would be stronger for mutable than for central properties, without finding evidence for this predicted interaction over the course of five experiments. However Experiment 6, which provided a brief context for the modified concepts to lend them greater credibility, did reveal the predicted interaction. It is argued that the modifier effect (...) arises primarily from a general lack of confidence in generic statements about the typical properties of unfamiliar concepts. Neither prototype nor classical models of concept combination receive support from the phenomenon. 2010 Elsevier Inc. All rights reserved. (shrink)

We can perceive shapes visually and tactilely, and the information we gain about shapes through both sensory modalities is integrated smoothly into and functions in the same way in our behavior independently of whether we gain it by sight or touch. There seems to be no reason in principle we couldn't perceive shapes through other sensory modalities as well, although as a matter of fact we do not. While we can identify shapes through other sensory modalities—e.g., I may know by (...) smell (the scent of mango) that the object causing my sensory experience is round—this is not perceiving an object as shaped, but rather inferring from the character of one's sensory experience and collateral information that an object of a certain shape caused it. That it is possible to perceive shape by other modalities, however, is suggested by the case of bats and aquatic mammals like dolphins which navigate through their environment by a form of sonar. It is plausible that they have some form of auditory representation of space, and so of shape. These facts about shape perception raise important questions about the relation between those features of perceptual experience which are intrinsic to different sensory modalities and the nature of our perceptual representation of shapes, and, more generally, of the space within which we perceive shaped objects to be located. John Campbell's paper, "Molyneux's Problem" (see above), raises a number of interesting and important questions about the nature of our perception of shape properties, particularly the cross-modal nature of shape perception, and ties them to more general questions about the nature both of perceptual..

In this paper, I critically assess the enactive account of visual perception recently defended by Alva Noë (2004). I argue inter alia that the enactive account falsely identifies an object’s apparent shape with its 2D perspectival shape; that it mistakenly assimilates visual shape perception and volumetric object recognition; and that it seriously misrepresents the constitutive role of bodily action in visual awareness. I argue further that noticing an object’s perspectival shape involves a hybrid experience combining both perceptual and imaginative elements—an (...) act of what I call ‘make‐perceive’. (shrink)

A prominent view holds that perception and memory are distinguished at least partly by their temporal orientation: Perception functions to represent the present, while memory functions to represent the past. Call this view perceptual presentism. This chapter critically examines perceptual presentism in light of contemporary perception science. I adduce evidence for three forms of perceptual sensitivity to the past: (i) shaping perception by past stimulus exposure, (ii) recruitment of mnemonic representations in perceptual processing, and (iii) perceptual representation of present objects (...) as possessing past properties. I argue that forms (i) and (ii) are consistent with perceptual presentism, while form (iii) poses a genuine threat to the view. While the empirical case for form (iii) remains inconclusive, I suggest that the most serious challenges to perceptual presentism derive from representations that integrate mnemonic and present-tensed elements in the performance of canonical perceptual functions, such as perceiving object continuity over time.

In identifying intrinsic molecular chance and extrinsic adaptive pressures as the only causally relevant factors in the process of evolution, the theoretical perspective of the Modern Synthesis had a major impact on the perceived tenability of an ontology of dispositional properties. However, since the late 1970s, an increasing number of evolutionary biologists have challenged the descriptive and explanatory adequacy of this “chance alone, extrinsic only” understanding of evolutionary change. Because morphological studies of homology, convergence, and teratology have revealed (...) a space of possible forms and phylogenetic trajectories that is considerably more restricted than expected, evo-devo has focused on the causal contribution of intrinsic developmental processes to the course of evolution. Evo-devo’s investigation into the developmental structure of the modality of morphology – including both the possibility and impossibility of organismal form – has led to the utilisation of a number of dispositional concepts that emphasise the tendency of the evolutionary process to change along certain routes. In this sense, and in contrast to the perspective of the Modern Synthesis, evo-devo can be described as a “science of dispositions.” This chapter discusses the recent philosophical literature on dispositional properties in evo-devo, exploring debates about both the metaphysical and epistemological aspects of the central dispositional concepts utilised in contemporary evo-devo and addressing the epistemological question of how dispositional properties challenge existing explanatory models in evolutionary biology.

In this paper I will argue that ‘colour’ is not in real objects. I will then go beyond that to argue that properties of real objects – if they have properties – cannot be emitted to the perceiver. It becomes necessary, therefore, to hold that all that is ‘known’, via the senses, of the world be inferred from the Representation only.

It is widely agreed upon that aesthetic properties, such as grace, balance, and elegance, are perceived. I argue that aesthetic properties are experientially attributed to some non‐perceptible objects. For example, a mathematical proof can be experienced as elegant. In order to give a unified explanation of the experiential attribution of aesthetic properties to both perceptible and non‐perceptible objects, one has to reject the idea that aesthetic properties are perceived. I propose an alternative view: the (...) affective account. I argue that the standard case of experiential aesthetic property attribution is affective experience. (shrink)

In this paper I will try to trace a discussion about status of art in some recent theories, which pay special attention to the fact that artworks are the kind of things to which representational, expressive, and aesthetic properties are ascribed. First, I will briefly mention some already established criticisms—developed by Richard Wollheim1—against the idea that artworks cannot be identified with physical objects. These criticisms have the further aim of providing an account of art experience that includes our perceiving (...) representational and expressive properties as well as aesthetic ones in artworks. In Wollheim's view, a misconstruction of the nature of these properties and of our perception of them in artworks has been the main reason for the view he intensely criticizes. Thus, he offers a different understanding of these properties, which also involves a new account of perception that does not require an idealisation of our experience of art. (shrink)

Both common sense and dominant traditions in art criticism and philosophical aesthetics have it that aesthetic features or properties are perceived. However, there is a cast of reasons to be sceptical of the thesis. This paper defends the thesis—that aesthetic properties are sometimes represented in perceptual experience—against one of those sceptical opponents. That opponent maintains that perception represents only low-level properties, and since all theorists agree that aesthetic properties are not low-level properties, perception does (...) not represent aesthetic properties. I offer a novel argument—what I call the argument from seeing-as—against that sceptic which moves from consideration of ambiguous figures to consideration of visual art. It concludes that aesthetic properties are sometimes perceived and delivers a general lesson for philosophy of perception. Contrary to extant theories of rich perceptual content, aesthetic properties are far better candidates for high-level perceptual contents than standardly theorized rich contents like natural kinds.

I defend the claim that we have the capacity to perceptually represent objects and events in experience as deviating from an expectation, or, for short, as deviant. The rival hypothesis is that we may ascribe the property of deviance to a stimulus at a cognitive level, but that property is not a representational content of perceptual experience. I provide empirical reasons to think that, contrary to the rival hypothesis, we do perceptually represent deviance.

In our everyday interaction with the environment, we often perceive objects and spaces as opportunities to feel, maintain, enhance, and change our affective states and processes. The concept of affective affordance was coined to accommodate this aspect of ordinary perception and the many ways in which we rely on the material environment to regulate our emo- tions. One natural way to think of affective affordances in emotion regulation is to interpret them as tools for regulating felt affective states. We argue (...) that this way of conceiving of affective affordances is too restrictive. By analyzing the role of expressive properties of objects and spaces in emotion regulation, we show that our environment does not need to elicit felt affective states to regulate our emotions. Thus, we revise the concept of affective affordance to accommodate these cases. This revised concept explains more with less. Hence, it should be preferred in wide-reaching philosophical projects that aim to explain human affectivity as a situated phenomenon. (shrink)

Conservatives claim that all phenomenal properties are sensory. Liberals countenance non-sensory phenomenal properties such as what it’s like to perceive some high-level property, and what it’s like to think that p. A hallmark of phenomenal properties is that they present an explanatory gap, so to resolve the dispute we should consider whether experience has non-sensory properties that appear ‘gappy’. The classic tests for ‘gappiness’ are the invertibility test and the zombifiability test. I suggest that these tests (...) yield conflicting results: non-sensory properties lend themselves to zombie scenarios but not to inversion scenarios. Which test should we trust? Against Carruthers & Veillet (2011), I argue that invertibility is not a viable condition of phenomenality. In contrast, being zombifiable is credibly necessary and sufficient for phenomenality. I conclude that there are non-sensory properties of experience that are ‘gappy’ in the right way, and that liberalism is therefore the most plausible position. (shrink)

All accepted proofs of the Four Colour Theorem (4CT) are computer-dependent; and appeal to the existence, and manual identification, of an ‘unavoidable’ set containing a sufficient number of explicitly defined configurations—each evidenced only by a computer as ‘reducible’—such that at least one of the configurations must occur in any chromatically distinguished, minimal, planar map. For instance, Appel and Haken ‘identified’ 1,482 such configurations in their 1977, computer-dependent, proof of 4CT; whilst Neil Robertson et al ‘identified’ 633 configurations as sufficient in (...) their 1997, also computer-dependent, proof of 4CT. However, treating any specific number of ‘reducible’ configurations in an ‘unavoidable’ set as sufficient entails a minimum number as necessary and sufficient. We now show that the minimum number of such configurations can only be the one corresponding to the ‘unavoidable’ set of a ‘reducible’, 4-sided configuration identified by Alfred Kempe in his, seemingly fatally flawed, 1879 ‘proof’ of 4CT. Although Kempe appealed to putative properties of ‘Kempe’ chains in a graphical representation to fallaciously argue that a 5-sided configuration was also in the ‘unavoidable’ set, and ‘reducible’, we shall show why the flaw in his ‘proof’ is not fatal when the argument is expressed geometrically; and that, essentially, Kempe correctly argued that any planar map which admits a chromatic differentiation with a five-sided area C that shares non-zero boundaries with four, all differently coloured, neighbours can be 4-coloured.

Outside of philosophy, ‘intuition’ means something like ‘knowing without knowing how you know’. Intuition in this broad sense is an important epistemological category. I distinguish intuition from perception and perception from perceptual experience, in order to discuss the distinctive psychological and epistemological status of evaluative property attributions. Although it is doubtful that we perceptually experience many evaluative properties and also somewhat unlikely that we perceive many evaluative properties, it is highly plausible that we intuit many instances of evaluative (...) properties as such. The resulting epistemological status of evaluative property attributions is very much like it would be if we literally perceived such properties. (shrink)

ABSTRACT The main informational components of consciousness are described as Operative Informational System (OIS) assuring the reactive short-time adaptation and Programmed Informational System (PIS), assuring the life maintenance and the species survival, working in an integrated manner with the informed matter IM (body). The defined informational subsystems allow to describe consciousness as a sum of cognition centers defined by Ibelieve, Iknow, Iwant, Ilove, Iam, Icreate and Icreated. The cognition center Ibelieve was defined as related with the anti-entropic field of the (...) bipolar universal matter/antimatter informational system, assisting the life structuring and health and explaining the precognition, psychokinesis, near-death experiences and other "paranormal" phenomena. PIS related activity of the cognition centers was described as the projected data in OIS by two components: (1) personal status as survival needs; (2) the info-consequences on oneself perception and action impulses perceived by Iam, Icreate and Icreated, reflecting together with Iknow, Iwant and Ilove the "normal" (regular) mind properties.

It is well-known that naïve realism has difficulty accommodating perceptual error. Recent discussion of the issue has focused on whether the naïve realist can accommodate hallucination by adopting disjunctivism. However, illusions are more difficult for the naïve realist to explain precisely because the disjunctivist solution is not available. I discuss what I take to be the two most plausible accounts of illusion available to the naïve realist. The first claims that illusions are cases in which you are prevented from perceiving (...) properties you would ordinarily perceive and subsequently form a mistaken judgment about the perceived object. The second appeals to an unusual look or appearance that the perceived object instantiates. I argue that neither account is satisfactory and that, consequently, naïve realism ought to be rejected.

"Subjectivisation of Sense Perception and Two Models of Early Modern Idealism" The distinction between primary and secondary qualities, most famously outlined by Galileo, and subsequently supported, inter alia, by Descartes and by Locke has widely been considered one of the crucial factors in the development of modern idealism. In its contemporary form, the distinction identifies some of the perceived properties as mental phenomena due to their content and structural dependence on the mind. However, this account of the primary/secondary (...) distinction is largely different from its original version developed by the above-mentioned philosophers, within whose work the mental being of the perceived qualities was demonstrated objectively, from the conceptually-derived nature of matter, and not subjectively, by referring to the mind’s participation in the cognitive process. It was only at the next stage of the early modern subjectivisation of sense perception, best exemplified by such philosophers as Arnold Geulincx and Richard Burthogge, that the creative role played by the mind in sensation and, consequently, the mind-dependency of the sensible qualities was recognised – a turn influenced by the reinterpretation of Aristotelian philosophy offered by Jacopo Zabarella and Paduan school as well as by Anti-Aristotelianism of the kind developed in Netherlands. Furthermore, the two different approaches to the primary/secondary distinction can be linked with two main types of post-Cartesian idealism, i.e. Berkeleian and Kantian – a claim for which illustrative evidence from British philosophy, namely from Berkeley’s and Burthogge’s respective theories, can be drawn.

For Kant, a body fills out space by means of its causal efficacy. The essential properties of matter are hence dependent on underlying forces and it is one task of the Opus postumum (OP) to reconstruct the system of forces. In order to avoid an infinite regress of causal explanations, this system of forces needs to account for a primitive origin of all mechanical moving forces in something that is constitutive of forces, yet radically different - this is the (...) ether that fills all space that constantly moves or vibrates all the parts of the material bodies internally. I argue that we can read Kant’s argument for the existence of the ether through the lens of dispositions: essential properties of matter, such as ponderability, coercibility, cohesibility, and exhaustibility, should be understood as dispositions. These dispositions are ‘physically conditioned,’ as Kant calls it, on the ether. To display their manifest and perceivable properties, the ether acts as the ubiquitous and universal ‘activation stimulus’ of the dispositions that make up material bodies. He causes them to constantly display their manifest properties that make them continuously perceivable and causally efficient. Thereby Kant offers a solution to a problem formulated by Simon Blackburn, namely that purely dispositional matter would lead us into skepticism. (shrink)

Do we (sometimes) perceive apples as edible? One could argue that it is just a manner of speaking to say so: we do not really see an object as edible, we see it as having certain shape, size and color and we only infer on the basis of these properties that it is. I argue that we do indeed see objects as edible, and do not just believe that they are. My argument proceeds in two steps. First, I point (...) out that Susanna Siegel's influential argument in favor of the claim that we represent sortal properties perceptually does not work. Second, I argue that we can fix this argument if we replace the sortal property in question with the property of being edible, climbable or Q-able in general. (shrink)

You can perceive things, in many respects, as they really are. For example, you can correctly see a coin as circular from most angles. Nonetheless, your perception of the world is perspectival. The coin looks different when slanted than when head-on, and there is some respect in which the slanted coin looks similar to a head-on ellipse. Many hold that perception is perspectival because you perceive certain properties that correspond to the “looks” of things. I argue that this view (...) is misguided. I consider the two standard versions of this view. What I call the PLURALIST APPROACH fails to give a unified account of the perspectival character of perception, while what I call the PERSPECTIVAL PROPERTIES APPROACH violates central commitments of contemporary psychology. I propose instead that perception is perspectival because of the way perceptual states are structured from their parts. (shrink)

In Sense-certainty, the being of the particular object of sense was found to belong to the universality - of consciousness. This relationship between the universal truth of the object and its sensuous determinate particularity is called the Thing of Perception, basically a Thing and its perceived properties. However, in perception it was concluded that the particular Thing is ultimately resolved into the unconditioned universality of the Understanding. Thus in both Sense-certainty and Perception the particular object or Thing proves (...) to be essentially universality. It is important to recollect the development that has taken place up to this point, i.e., the various moments and movements of thinking that constitute the activity, or dynamic essence, of what is called, in totality, consciousness or knowing. The full explication of what consciousness is in its completely developed form has not yet been reached, but only what may broadly be referred to as the first three stages (Sense-certainty, Perception, Understanding) in the complete activity that will be necessary and sufficient to adequately comprehend consciousness. When the movement of consciousness is completed, the development will continue onward to the stages of Self-consciousness, Reason, and Spirit. (shrink)

Abstract: I defend the intuition that the phenomenology of our experience is right in attributing the colors we see to objects; but although colors are properties of objects, they are constitutively dependent on the perceiver’s experiences. I offer a metaphysical account for this primitivist intuition, in response to David Chalmers’ arguments against it, drawing inspiration from Aristotle’s theory of causation.

___MERGING of temporally distant events: One perceives a singular causal relation that c causes e whenever c instantiates a mental property C which anticipates a certain mental property E instantiated by e.

Abstract: When I throw a ball at you, do you see it as catch-able? Do we perceive objects as edible, climbable or Q-able in general? One could argue that it is just a manner of speaking to say so: we do not really see an object as edible, we only infer on the basis of its other properties that it is. I argue that whether or not an object is edible or climbable is indeed represented perceptually: we see objects (...) as edible, and do not just believe that they are. My argument proceeds in two steps. First, I argue that in order to perform an action Q with respect to an object, we need to represent this object as Q-able and, second, I argue that we represent objects as having these properties perceptually.

The chapter unfolds in the following sections. The first section exam- ines the reasons for claiming that olfactory perception is spatially unstruc- tured and our experience of smells has an abstract structure. The second section elucidates the further arguments that olfaction cannot generate figure-ground segregation. The third section assesses the conclusion that olfactory perception and experience cannot solve the MPP. Following the overview of the many problems inherent to distal olfactory percep- tion, MST will be introduced as an alternative perspective (...) that allows for figure-ground segregation and perceiving multiple olfactory objects within an array. The chapter then concludes by replying to the shared argument that olfactory distal perception does not have the requisite res- olution to resolve the many properties problem. (shrink)

While the view that we perceive aesthetic properties may seem intuitive, it has received little in the way of explicit defence. It also gives rise to a puzzle. The first strand of this puzzle is that we often cannot perceive aesthetic properties of artworks without training, yet much aesthetic training involves the acquisition of knowledge, such as when an artwork was made, and by whom. How, if at all, can this knowledge affect our perception of an artwork’s aesthetic (...) properties? The second strand of the puzzle arises when we widen the scope of aesthetic experience. The very same aesthetic properties that seem to require training for their perception in artworks do not appear to require training to perceive in objects of everyday aesthetic appreciation and natural phenomena. In this paper I argue that a prominent extant attempt to explain how training is compatible with aesthetic perception—cognitive permeation—is an inadequate solution. I also develop a positive view of aesthetic perception that provides a unified solution to both strands of the puzzle. (shrink)

It has been widely assumed that we do not perceive dispositional properties. I argue that there are two ways of interpreting this assumption. On the first, extensional, interpretation whether we perceive dispositions depends on a complex set of metaphysical commitments. But if we interpret the claim in the second, intensional, way, then we have no reason to suppose that we do not perceive dispositional properties. The two most important and influential arguments to the contrary fail.

Some experiments in perceptual psychology measure perceivers’ phenomenal experiences of objects versus their cognitive assessments of object properties. Analyzing such experiments, this article responds to Pizlo’s claim that much work on shape constancy before 1985 confused problems of shape ambiguity with problems of shape constancy. Pizlo fails to grasp the logic of experimental designs directed toward phenomenal aspects of shape constancy. In the domain of size perception, Granrud’s studies of size constancy in children and adults distinguish phenomenal from cognitive (...) factors. (shrink)

The ability to perceive the shapes of things as enduring through changes in how they stimulate our sense organs is vital to our sense of stability in the world. But what sort of capacity is shape constancy, and how is it reflected in perceptual experience? This paper defends a pluralist account of shape constancy: There are multiple kinds of shape constancy centered on geometrical properties at various levels of abstraction, and properties at these various levels feature in the (...) content of perceptual experience, governing patterns of apparent shape similarity. I propose that the varieties of shape constancy are subserved by the syntactic complexity of perceptual shape representations. By assigning discrete constituents to various abstract shape parameters, these representations attune us to the preservation of certain abstract shape properties through changes in more determinate shape properties. Finally, I draw broader lessons concerning the nature and function of perceptual constancy. (shrink)

When we perceive an object, we perceive the object from a perspective. As a consequence of the perspectival nature of perception, when we perceive, say, a circular coin from different angles, there is a respect in which the coin looks circular throughout, but also a respect in which the coin's appearance changes. More generally, perception of shape and size properties has both a constant aspect—an aspect that remains stable across changes in perspective—and a perspectival aspect—an aspect that changes depending (...) on one's perspective on the object. How should we account for the perspectival aspect of spatial perception? We present a framework within which to discuss the perspectival aspect of perception and put forward three desiderata that any account of the perspectival aspect of perception should satisfy. We discuss views on which the perspectival aspect of perception is analyzed in terms of constitutively mind-dependent appearance properties as well as views on which the perspectival aspect of perception is analyzed in terms of representations of mind-independent perspectival properties.

We introduce the notion of complexity, first at an intuitive level and then in relatively more concrete terms, explaining the various characteristic features of complex systems with examples. There exists a vast literature on complexity, and our exposition is intended to be an elementary introduction, meant for a broad audience. -/- Briefly, a complex system is one whose description involves a hierarchy of levels, where each level is made of a large number of components interacting among themselves. The time evolution (...) of such a system is of a complex nature, depending on the interactions among subsystems in the next level below the one under consideration and, at the same time, conditioned by the level above, where the latter sets the context for the evolution. Generally speaking, the interactions among the constituents of the various levels lead to a dynamics characterized by numerous characteristic scales, each level having its own set of scales. What is more, a level commonly exhibits ‘emergent properties’ that cannot be derived from considerations relating to its component systems taken in isolation or to those in a different contextual setting. In the dynamic evolution of some particular level, there occurs a self-organized emergence of a higher level and the process is repeated at still higher levels. -/- The interaction and self-organization of the components of a complex system follow the principle commonly expressed by saying that the ‘whole is different from the sum of the parts’. In the case of systems whose behavior can be expressed mathematically in terms of differential equations this means that the interactions are nonlinear in nature. -/- While all of the above features are not universally exhibited by complex systems, these are nevertheless indicative of a broad commonness relative to which individual systems can be described and analyzed. There exist measures of complexity which, once again, are not of universal applicability, being more heuristic than exact. The present state of knowledge and understanding of complex systems is itself an emerging one. Still, a large number of results on various systems can be related to their complex character, making complexity an immensely fertile concept in the study of natural, biological, and social phenomena. -/- All this puts a very definite limitation on the complete description of a complex system as a whole since such a system can be precisely described only contextually, relative to some particular level, where emergent properties rule out an exact description of more than one levels within a common framework. -/- We discuss the implications of these observations in the context of our conception of the so-called noumenal reality that has a mind-independent existence and is perceived by us in the form of the phenomenal reality. The latter is derived from the former by means of our perceptions and interpretations, and our efforts at sorting out and making sense of the bewildering complexity of reality takes the form of incessant processes of inference that lead to theories. Strictly speaking, theories apply to models that are constructed as idealized versions of parts of reality, within which inferences and abstractions can be carried out meaningfully, enabling us to construct the theories. -/- There exists a correspondence between the phenomenal and the noumenal realities in terms of events and their correlations, where these are experienced as the complex behavior of systems or entities of various descriptions. The infinite diversity of behavior of systems in the phenomenal world are explained within specified contexts by theories. The latter are constructs generated in our ceaseless attempts at interpreting the world, and the question arises as to whether these are reflections of `laws of nature' residing in the noumenal world. This is a fundamental concern of scientific realism, within the fold of which there exists a trend towards the assumption that theories express truths about the noumenal reality. We examine this assumption (referred to as a ‘point of view’ in the present essay) closely and indicate that an alternative point of view is also consistent within the broad framework of scientific realism. This is the view that theories are domain-specific and contextual, and that these are arrived at by independent processes of inference and abstractions in the various domains of experience. Theories in contiguous domains of experience dovetail and interpenetrate with one another, and bear the responsibility of correctly explaining our observations within these domains. -/- With accumulating experience, theories get revised and the network of our theories of the world acquires a complex structure, exhibiting a complex evolution. There exists a tendency within the fold of scientific realism of interpreting this complex evolution in rather simple terms, where one assumes (this, again, is a point of view) that theories tend more and more closely to truths about Nature and, what is more, progress towards an all-embracing ‘ultimate theory’ -- a foundational one in respect of all our inquiries into nature. We examine this point of view closely and outline the alternative view -- one broadly consistent with scientific realism -- that there is no ‘ultimate’ law of nature, that theories do not correspond to truths inherent in reality, and that successive revisions in theory do not lead monotonically to some ultimate truth. Instead, the theories generated in succession are incommensurate with each other, testifying to the fact that a theory gives us a perspective view of some part of reality, arrived at contextually. Instead of resembling a monotonically converging series successive theories are analogous to asymptotic series. -/- Before we summarize all the above considerations, we briefly address the issue of the complexity of the {\it human mind} -- one as pervasive as the complexity of Nature at large. The complexity of the mind is related to the complexity of the underlying neuronal organization in the brain, which operates within a larger biological context, its activities being modulated by other physiological systems, notably the one involving a host of chemical messengers. The mind, with no materiality of its own, is nevertheless emergent from the activity of interacting neuronal assemblies in the brain. As in the case of reality at large, there can be no ultimate theory of the mind, from which one can explain and predict the entire spectrum of human behavior, which is an infinitely rich and diverse one.

John Hick’s theory concerning plurality of religions is an ontologic pluralism according to which all religions are authentic ways for man to attain the "real an sich". Gods of religions are real as perceived and veridical hallucinations; while the “real an sich” has ineffable substantial and trans-categorical properties. Hick’s view suffers from several problems. As a second order analysis of religions, Hick’s view is not a correct one. To reject naturalism, it falls into an epistemological circle, where distinction (...) between formal and substantial properties fades away. It seems that Hick is captured by a category mistake in the presentation of his own theory concerning authenticity of all religions to attain the "real an sich". (shrink)
