When we see an object, we also represent those parts of it that are not visible. The question is how we represent them: this is the problem of amodal perception. I will consider three possible accounts: (a) we see them, (b) we have non-perceptual beliefs about them and (c) we have immediate perceptual access to them, and point out that all of these views face both empirical and conceptual objections. I suggest and defend a fourth account, according to which we (...) represent the occluded parts of perceived objects by means of mental imagery. This conclusion could be thought of as a (weak) version of the Strawsonian dictum, according to which “imagination is a necessary ingredient of perception itself”. (shrink)

The aim of this paper is to argue that the phenomenal similarity between perceiving and visualizing can be explained by the similarity between the structure of the content of these two different mental states. And this puts important constraints on how we should think about perceptual content and the content of mental imagery.

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)

I argue that perceptual content is always affected by the allocation of one’s attention. Perception attributes determinable and determinate properties to the perceived scene. Attention makes (or tries to make) our perceptual attribution of properties more determinate. Hence, a change in our attention changes the determinacy of the properties attributed to the perceived scene.

We argue that recent empirical findings and theoretical models shed new light on the nature of attention. According to the resulting amplification view, attentional phenomena can be unified at the neural level as the consequence of the amplification of certain input signals of attention-independent perceptual computations. This way of identifying the core realizer of attention evades standard criticisms often raised against sub-personal accounts of attention. Moreover, this approach also reframes our thinking about the function of attention by shifting the focus (...) from the function of selection to the function of amplification. (shrink)

The function of a trait token is usually defined in terms of some properties of other (past, present, future) tokens of the same trait type. I argue that this strategy is problematic, as trait types are (at least partly) individuated by their functional properties, which would lead to circularity. In order to avoid this problem, I suggest a way to define the function of a trait token in terms of the properties of the very same trait token. To able to (...) allow for the possibility of malfunctioning, some of these properties need to be modal ones: a function of a trait is to do F just in case its doing F would contribute to the inclusive fitness of the organism whose trait it is. Function attributions have modal force. Finally, I explore whether and how this theory of biological function could be modified to cover artifact function. (shrink)

Historically, mental imagery has been defined as an experiential state - as something necessarily conscious. But most behavioural or neuroimaging experiments on mental imagery - including the most famous ones - don’t actually take the conscious experience of the subject into consideration. Further, recent research highlights that there are very few behavioural or neural differences between conscious and unconscious mental imagery. I argue that treating mental imagery as not necessarily conscious (as potentially unconscious) would bring much needed explanatory unification to (...) mental imagery research. It would also help us to reassess some of the recent aphantasia findings inasmuch as at least some subjects with aphantasia would be best described as having unconscious mental imagery. (shrink)

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. (shrink)

What is the mental representation that is responsible for implicit bias? What is this representation that mediates between the trigger and the biased behavior? My claim is that this representation is neither a propositional attitude nor a mere association. Rather, it is mental imagery: perceptual processing that is not directly triggered by sensory input. I argue that this view captures the advantages of the two standard accounts without inheriting their disadvantages. Further, this view also explains why manipulating mental imagery is (...) among the most efficient ways of counteracting implicit bias. (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)

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. (shrink)

Amodal completion is the representation of occluded parts of perceived objects. We argue for the following three claims: First, at least some amodal completion-involved experiences can ground knowledge about the occluded portions of perceived objects. Second, at least some instances of amodal completion-grounded knowledge are not sensitive, that is, it is not the case that in the nearest worlds in which the relevant claim is false, that claim is not believed true. Third, at least some instances of amodal completion-grounded knowledge (...) are not safe, that is, it is not the case that in all or nearly all near worlds where the relevant claim is believed true, that claim is in fact true. Thus, certain instances of amodal completion-grounded knowledge refute both the view that knowledge is necessarily sensitive and the view that knowledge is necessarily safe. (shrink)

The aim of teleosemantics is to give a scientifically respectable, or ‘naturalistic’ theory of mental content. In the debates surrounding the scope and merits of teleosemantics a lot has been said about the concept of indication (or carrying information). The aim of this paper is to focus on the other key concept of teleosemantics: biological function. It has been universally accepted in the teleosemantics literature that the account of biological function one should use to flesh out teleosemantics is that of (...) etiological function. My claim is that if we replace this concept of function with an alternative one (that we have independent reasons to accept) and if we also restrict the scope of teleosemantics, we can arrive at an account of biologizing mental content that is much less problematic than the previous attempts. (shrink)

Relationalism holds that perceptual experiences are relations between subjects and perceived objects. But much evidence suggests that perceptual states can be unconscious. We argue here that unconscious perception raises difficulties for relationalism. Relationalists would seem to have three options. First, they may deny that there is unconscious perception or question whether we have sufficient evidence to posit it. Second, they may allow for unconscious perception but deny that the relationalist analysis applies to it. Third, they may offer a relationalist explanation (...) of unconscious perception. We argue that each of these strategies is questionable. (shrink)

There are two very different ways of thinking about perception. According to representationalism, perceptual states are representations: they represent the world as being a certain way. They have content, which may or may not be different from the content of beliefs. They represent objects as having properties, sometimes veridically, sometimes not. According to relationalism, perception is a relation between the agent and the perceived object. Perceived objects are literally constituents of our perceptual states and not of the contents thereof. Perceptual (...) states are not representations. My aim is to argue that if we frame this debate as a debate about the individuation of perceptual states, rather than the nature of perception, then we can reconcile these two seemingly conflicting ways of thinking about perception. (shrink)

The psychological mechanism of decision-making has traditionally been modeled with the help of belief-desire psychology: the agent has some desires (or other pro-attitudes) and some background beliefs and deciding between two possible actions is a matter of comparing the probability of the satisfaction of these desires given the background beliefs in the case of the performance of each action. There is a wealth of recent empirical findings about how we actually make decisions that seems to be in conflict with this (...) picture. My aim is to outline an alternative model that is consistent with these empirical findings. This alternative model emphasizes the role imagination plays in our decisions: when we decide between two possible actions, we imagine ourselves in the situation that we imagine to be the outcome of these two actions and then compare these two imaginings. (shrink)

Look at a red apple. Now close your eyes and visualize this apple. Your perceptual state and your imagery of the apple are very similar in some respects. They are also different in some respects. The aim of this paper is to address three questions about the relation between perception and imagination: -/- (a) How similar are perception and imagination and what explains this similarity? (b) How different are perception and imagination and what explains this difference? (c) How do perception (...) and imagination interact? (shrink)

Intentionalism about visual experiences is the view according to which the phenomenal character of a visual experience supervenes on the content of this experience. One of the most influential objections to this view is about blur: seeing a fuzzy contour clearly and seeing a sharp contour blurrily have different phenomenal character but the same content. I argue that this objection does not work if we understand perceptual content simply, and not particularly controversially, as partly constituted by the sum total of (...) perceptually attributed properties, some determinable, some determinate. (shrink)

While there has been a lot of discussion of picture perception both in perceptual psychology and in philosophy, these discussions are driven by very different background assumptions. Nonetheless, it would be mutually beneficial to arrive at an understanding of picture perception that is informed by both the philosophers’ and the psychologists’ story. The aim of this paper is exactly this: to give an account of picture perception that is valid both as a philosophical and as a psychological account. I argue (...) that seeing trompe l’oeil paintings is, just as some philosophers suggested, different from other cases of picture perception. Further, the way our perceptual system functions when seeing trompe l’oeil paintings could be an important piece of the psychological explanation of perceiving pictures. (shrink)

We experience resistance when we are engaging with fictional works which present certain (for example, morally objectionable) claims. But in virtue of what properties do sentences trigger this ‘imaginative resistance’? I argue that while most accounts of imaginative resistance have looked for semantic properties in virtue of which sentences trigger it, this is unlikely to give us a coherent account, because imaginative resistance is a pragmatic phenomenon. It works in a way very similar to Paul Grice's widely analysed ‘conversational implicature’.

I am looking at an apple. The apple has a lot of properties and some, but not all, of these are part of my phenomenology at this moment: I am aware of these properties. And some, but not all, of these properties that I am aware of are part of my perceptual (or sensory) phenomenology. If I am attending to the apple’s color, this property will be part of my perceptual phenomenology. The property of being a granny smith apple from (...) Chile is unlikely to be part of my perceptual phenomenology. Here are two problems for anyone who is interested in conscious experience in general, and perceptual experience in particular: (a) How can we tell which properties are part of our phenomenology and which ones are not? (b) How can we tell which properties are part of our perceptual phenomenology and which ones are part of our non-perceptual phenomenology? I will focus on (b) in this paper. My aim is twofold: I propose a methodology for answering the question of which properties are part of our perceptual phenomenology and I provide an example for how this methodology could be applied. (shrink)

What are the sensory individuals of audition? What are the entities our auditory system attributes properties to? We examine various proposals about the nature of the sensory individuals of audition, and show that while each can account for some aspects of auditory perception, each also faces certain difficulties. We then put forward a new conception of sensory individuals according to which auditory sensory individuals are composite individuals. A feature shared by all existing accounts of sounds and sources is that they (...) postulate sensory individuals that are non-composite. They identify the sensory individual of sound hearing or source hearing with one type of entity in the environment, be they sound waves, vibrations, or interactions. We question this assumption and argue that our perceptual systems represent two or more aspects of the environment as a single sensory individual. Finally, we show that taking auditory individuals to be composite sensory individuals allows for an account of audition that is less problematic than its existing alternatives. (shrink)

I aim to show that perception depends counterfactually on the action we want to perform. Perception is not all-purpose: what we want to do does influence what we see. After clarifying how this claim is different from the one at stake in the cognitive penetrability debate and what counterfactual dependence means in my claim, I will give a two-step argument: one’s perceptual attention depends counterfactually on one’s intention to perform an action and one’s perceptual processing depends counterfactually on one’s perceptual (...) attention. If we put these claims together, what we get is that one’s perceptual processing depends counterfactually on one’s intention to perform an action. (shrink)

The aim of this paper is to reinterpret success semantics, a theory of mental content, according to which the content of a belief is fixed by the success conditions of some actions based on this belief. After arguing that in its present form, success semantics is vulnerable to decisive objections, I examine the possibilities of salvaging the core of this proposal. More specifically, I propose that the content of some very simple, but very important, mental states, the immediate mental antecedents (...) of action, can be explained in this manner. (shrink)

The aim of this paper is to give a new account of the way we exercise our attention in some paradigmatic cases of aesthetic experience. I treat aesthetic experience as a specific kind of experience and like in the case of other kinds of experiences, attention plays an important role in determining its phenomenal character. I argue that an important feature of at least some of our aesthetic experiences is that we exercise our attention in a specific, distributed, manner: our (...) attention is focused on one perceptual object, but it is distributed among the various properties of this object. I argue that this way of exercising one’s attention is very different from the way we attend most of the time and it fits very well with some important features of paradigmatic examples of aesthetic experience. (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)

Some of our aesthetic experiences are of artworks. Some others are of everyday scenes. The question I examine in this paper is about the relation between these two different kinds of aesthetic experience. I argue that the experience of artworks can dispose us to experience everyday scenes in an aesthetic manner both short-term and long-term. Finally, I examine what constraints this phenomenon puts on different accounts of aesthetic experience.

Hallucination is a big deal in contemporary philosophy of perception. The main reason for this is that the way hallucination is treated marks an important stance in one of the most hotly contested debates in this subdiscipline: the debate between 'relationalists' and 'representationalists'. I argue that if we take hallucinations to be a form of mental imagery, then we have a very straightforward way of arguing against disjunctivism: if hallucination is a form of mental imagery and if mental imagery and (...) perception have some substantive common denominator, then a fortiori, perception and hallucination will also have a substantive common denominator. (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.

Perceptual experiences justify beliefs. A perceptual experience of a dog justifies the belief that there is a dog present. But there is much evidence that perceptual states can occur without being conscious, as in experiments involving masked priming. Do unconscious perceptual states provide justification as well? The answer depends on one’s theory of justification. While most varieties of externalism seem compatible with unconscious perceptual justification, several theories have recently afforded to consciousness a special role in perceptual justification. We argue that (...) such views face a dilemma: either consciousness should be understood in functionalist terms, in which case our best current theories of consciousness do not seem to imbue consciousness with any special epistemic features, or it should not, in which case it is mysterious why only conscious states are justificatory. We conclude that unconscious perceptual justification is quite plausible. (shrink)

The aim of the paper is to argue that the difference between creative and non-creative mental processes is not a functional/computational, but an experiential one. In other words, what is distinctive about creative mental processes is not the functional/computational mechanism that leads to the emergence of a creative idea, be it the recombination of old ideas or the transformation of one’s conceptual space, but the way in which this mental process is experienced. The explanatory power of the functional/computational theories and (...) the experiential account is compared and it is pointed out that if creativity is a natural kind, it is not a functional/computational, but an experiential natural kind.

The concept of mental representation has long been considered to be central concept of philosophy of mind and cognitive science. But not everyone agrees. Neo-behaviorists aim to explain the mind without positing any representations. My aim here is not to assess the merits and demerits of neo-behaviorism, but to take their challenge seriously and ask the question: What justifies the attribution of representations to an agent? Both representationalists and neo-behaviorists tend to take it for granted that the real question about (...) representations is whether we should be realist about the theory of representationalism. This paper is an attempt to shift the emphasis from the debate concerning realism about theories to the one concerning realism about entities. My claim is that regardless of whether we are realist about representational theories of the mind, we have compelling reasons to endorse entity realism about mental representations. (shrink)

The Perky experiments are taken to demonstrate the phenomenal similarity between perception and visualization. Robert Hopkins argues that this interpretation should be resisted because it ignores an important feature of the experiments, namely, that they involve picture perception, rather than ordinary seeing. My aim is to point out that the force of this argument depends on one’s views on picture perception. On what I take to be the most mainstream account of picture perception, Hopkins’s argument does not work. But even (...) if we accept Hopkins’s own account, we have good reasons to believe that his conclusion does not follow. (shrink)

Two strong arguments have been given in favor of the claim that no selection process can play a role in explaining adaptations. According to the first argument, selection is a negative force; it may explain why the eliminated individuals are eliminated, but it does not explain why the ones that survived (or their offspring) have the traits they have. The second argument points out that the explanandum and the explanans are phenomena at different levels: selection is a population-level phenomenon, whereas (...) adaptation occurs on the individual level. Thus, selection can explain why individuals in a certain population have a certain trait, but it cannot explain why a certain indi- vidual has this trait. After pointing out that both arguments ignore the significance of the limitation of environmental resources, I will construe a positive argument for the claim that cumulative selection processes can, indeed, play a role in explaining adaptations. (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)

Wayne Wu argues that attention is necessary for action: since action requires a solution to the ‘Many–Many Problem’, and since only attention can solve the Many–Many Problem, attention is necessary for action. We question the first of these two steps and argue that it is based on an oversimplified distinction between actions and reflexes. We argue for a more complex typology of behaviours where one important category is action that does not require a solution to the Many–Many Problem, and so (...) does not require attention. (shrink)

The aim of this paper is to raise some serious worries about anti-representationalism: the recently popular view according to which there are no perceptual representations. Although anti-representationalism is more and more popular, I will argue that we have strong empirical reasons for mistrusting it. More specifically, I will argue that it is inconsistent with some important empirical findings about dorsal perception and about the multimodality of perception.

It has been argued that picture perception is sometimes, but not always, ‘inflected’. Sometimes the picture’s design ‘inflects’, or is ‘recruited’ into the depicted scene. The aim of this paper is to cash out what is meant by these metaphors. Our perceptual state is different when we see an object fact to face or when we see it in a picture. But there is also a further distinction: our perceptual state is very different if we perceive objects in pictures in (...) an inflected or uninflected manner. The question is what this difference amounts to. My answer is that it is a difference of attention. In the case of inflected, but not uninflected, picture perception, we are consciously attending to certain properties: to relational property that cannot be fully characterized without reference to both the picture’s design and to the depicted object. I defend this way of interpreting inflected picture perception from some important objections and emphasize the importance of this, inflected, way of perceiving pictures. (shrink)

Richard Wollheim claimed that twofoldness is a necessary condition for the perception of pictorial representations and it is also a necessary condition for the aesthetic appreciation of pictures. Jerrold Levinson pointed out that these two questions are different and argued that though twofoldness may be a necessary condition for the aesthetic appreciation of pictures, it cannot be a necessary condition for the perception of pictorial representations. I argue that Wollheim's use of the term ‘twofoldness’ alternates between two concepts: the simultaneous (...) visual awareness of the surface and of the represented object on the one hand and the simultaneous visual awareness of the represented object and the way it is represented on the other. Finally, I argue that twofoldness in the first sense is a necessary condition for the perception of pictorial representations, whereas twofoldness in the second sense is a necessary condition for the aesthetic appreciation of pictures.

Here is a widespread but controversial idea: those animals who represent correctly are likely to be selected over those who misrepresent. While various versions of this claim have been traditionally endorsed by the vast majority of philosophers of mind, recently, it has been argued that this is just plainly wrong. My aim in this paper is to argue for an intermediate position: that the correctness of some but not all representations is indeed selectively advantageous. It is selectively advantageous to have (...) correct representations that are directly involved in bringing about and guiding the organism's action. I start with the standard objection to the claim that it is selectively advantageous to represent correctly, the ‘better safe than sorry’ argument gand then generalize it with the help of Peter Godfrey Smith's distinction between Cartesian and Jamesian reliability and the trade‐off between them. This generalized argument rules out a positive answer to our question at least as far as the vast majority of our representational apparatus is concerned. But this argument fails to apply in the case of the correctness of a special kind of representation, one that is directly involved in bringing about, and in guiding, actions. We can still maintain that it is selectively advantageous to have a reliable mechanism for producing representations of this kind. (shrink)

It has been claimed that photographs are transparent: we see through them; we literally see the photographed object through the photograph. Whether this claim is true depends on the way we conceive of seeing. There has been a controversy about whether localizing the perceived object in one's egocentric space is a necessary feature of seeing, as if it is, then photographs are unlikely to be transparent. I would like to propose and defend another, much weaker, necessary condition for seeing: I (...) argue that it is necessary for seeing that there is at least one way for me to move such that if I were to move this way, my view of the perceived object would change continuously as I move. Since this condition is not satisfied in the case of seeing objects in photographs, photographs are not transparent. (shrink)

Analytic aesthetics has been obsessed with mature, art historically well-informed aesthetic judgment. But the vast majority of our engagement with art fails to take the form of this kind of judgment. Crucially, there seems to be a disconnect between taking pleasure in art and forming mature, well-informed judgments about it. My aim is to shift the emphasis away from aesthetic judgments to ways of engaging with works of art that are more enjoyable, more rewarding and happen to us more often.

The question of whether cognition can influence perception has a long history in neuroscience and philosophy. Here, we outline a novel approach to this issue, arguing that it should be viewed within the framework of top-down information-processing. This approach leads to a reversal of the standard explanatory order of the cognitive penetration debate: we suggest studying top-down processing at various levels without preconceptions of perception or cognition. Once a clear picture has emerged about which processes have influences on those at (...) lower levels, we can re-address the extent to which they should be considered perceptual or cognitive. Using top-down processing within the visual system as a model for higher-level influences, we argue that the current evidence indicates clear constraints on top-down influences at all stages of information processing; it does, however, not support the notion of a boundary between specific types of information-processing as proposed by the cognitive impenetrability hypothesis. (shrink)

It has been argued that the attribution of intentional actions is sensitive to our moral judgment. I suggest an alternative, where the attribution of intentional actions depends on modal (and not moral) considerations. We judge a foreseen side-effect of an agent’s intentionally performed action to be intentional if the following modal claim is true: if she had not ignored considerations about the foreseen side-effect, her action might have been different (other things being equal). I go through the most important examples (...) of the asymmetry in the attribution of intentionality and point out that the modal account can cover all the problematic cases, whereas the moral account can’t.

Intentionalism is the view that perceptual phenomenology depends on perceptual content. The aim of this paper is to make explicit an ambiguity in usual formulations of intentionalism, and to argue in favor of one way to disambiguate it. It concerns whether perceptual phenomenology depends on the content of one and only one representation (often construed as being identical to a certain perceptual experience), or instead depends on a collection of many different representations throughout the perceptual system. We argue in favor (...) of the latter option. Intentionalism so conceived can make better sense of contemporary neuroscience of perception, and is better equipped to confront several influential objections to traditional intentionalism. (shrink)

In this paper, I am clarifying and defending my argument in favor of the claim that cumulative selection can explain adaptation provided that the environmental resources are limited. Further, elaborate on what this limitation of environmental resources means and why it is relevant for the explanatory power of natural selection.

This chapter has four parts. I distinguishes some types of perceptual skills and highlights their importance in everyday perception. II identifies a well-studied class of perceptual skills: cases of perceptual expertise. III discusses a less studied possible instance of perceptual skill: picture perception. Finally, IV outlines some important mechanisms underlying perceptual skills, with special emphasis on attention and mental imagery.

It has been argued that some recent experimental findings about the mere exposure effect can be used to argue for aesthetic antirealism: the view that there is no fact of the matter about aesthetic value. The aim of this paper is to assess this argument and point out that this strategy, as it stands, does not work. But we may still be able to use experimental findings about the mere exposure effect in order to engage with the aesthetic realism/antirealism debate. (...) However, this argument would need to proceed very differently and would only support a much more modest version of aesthetic antirealism. (shrink)

According to the Ability Hypothesis, knowing what it is like to have experience E is just having the ability to imagine or recognize or remember having experience E. I examine various versions of the Ability Hypothesis and point out that they all face serious objections. Then I propose a new version that is not vulnerable to these objections: knowing what it is like to experience E is having the ability to discriminate imagining or having experience E from imagining or having (...) any other experience. I argue that if we replace the ability to imagine or recognize with the ability to discriminate, the Ability Hypothesis can be salvaged. (shrink)
