Added by: Andrea Blomqvist, Contributed by: Will HornettAbstract: What colour does a white wall look in the pinkish light of the late afternoon? What shape does a circular table look when you are standing next to it? These questions seem simple enough, but philosophers disagree sharply about them. In this paper, I attempt to provide a new approach to these questions, based on the idea that perception modifies our epistemic dispositions regarding specific environmental objects. I shall argue that by determining which object is involved in this way, we can determine the subject of visual predication. This enables us to parcel out visual features to different visual objects in a way that enables us to reconcile conflicting philosophical intuitions.Comment: Matthen's discussion of perceptual constancy is very clear and is centered on a philosophical analysis of the perceptual psychology. For this reason, it serves as a useful empirically informed companion to other philosophical discussions of perceptual constancy which are less empirically informed. It would be great in a third year or postgraduate course in Philosophy of Perception.

Added by: Clotilde Torregrossa, Contributed by: Nora HeinzelmannAbstract: Is it possible that a person who behaves just like you and me in normal life situations and applies colour words to objects just as we do and makes the same colour discriminations and colour similarity judgements that we make, see green where we see red and red where we see green? Many philosophers assert that the description of such a case is somehow incoherent. Often the motivation for this assertion is "that they suspect that admitting that claim [the possibility of such a case] will put one on a slippery slope which will eventually land one in skepticism about other minds".1 Among philosophers, however, it does not seem to be common knowledge that there is scientific evidence for the existence of such cases. Theories about the physiological basis of colour vision deficiencies together with theories about the genetics of colour vision deficiencies lead to the prediction that some people are 'pseudo- normal' (according to an estimation of Piantanida (1974) this occurs in around 14 of 10 000 males). 2 Pseudonormal people "would be expected to have normal colour vision except that the sensations of red and green would be reversed - something that would be difficult, if not impossible, to prove. ''3 Any philosophical theory of mind or more specifically about colour, colour appearances or colour concepts should meet the following plausible prima facie constraint: No hypotheses accepted or seriously considered in colour vision science should be regarded according to a philosophical theory to be either incoherent or unstatable or false. Therefore - regardless of whether the hypothesis of the existence of pseudonormal people is correct- the mere fact that the hypothesis is seriously considered in colour vision science, is philosophically relevant. Central claims of colour vision science when combined with specific empirical assumptions lead to the prediction that there are red-green-inverted people. Therefore any philosophical theory which excludes such a case does not meet the above formulated constraint. The failure to meet this prima facie constraint does not in itself justify the rejection of a philosophical proposal, but it does represent a serious objection. This kind of criticism will be advanced against some widely held philosophical proposals in the present paper. But let me begin with a short sketch of the relevant parts of colour vision science.

Added by: Clotilde Torregrossa, Contributed by: Nora HeinzelmannAbstract: When I look at a colored object I have an experience of a specific phenomenal kind. Let us suppose I have an experience of pure blue. The blueness I see appears to be instantiated on the surface of the object. When I focus upon the specific phenomenal kind of visual experience I am having (on my having an experience of pure blue) I continue to carefully attend to the property the object appears to have and I do not direct my attention into some inner space. I do not get aware - by attending to my own experience - of the instantiation of any property I was not already aware of before I focused attention upon my own experience. These insights have been associated with the idea that perceptual experience is 'transparent' or 'diaphanous' and they have been taken to support a number of substantial philosophical claims about the nature of phenomenal states and about our capacity to attend to these states. It has been argued that these phenomenological insights support the claim that the phenomenal character of experiences consists in their representing objects as having specific properties (where representation is understood in a naturalistic manner). It also has appeared obvious to some philosophers that the so?called transparency of experience supports the following claim: either our experiences do not have an intrinsic phenomenal character or we are unable to attend to these intrinsic features. I will argue in this paper that the phenomenological insights associated with the term 'transparency of experience' do not support the philosophical consequences just mentioned. I will try to show that the contrary impression is a cognitive illusion that can be explained by reference to what one may call the perceptual model of phenomenal awareness and phenomenological reflection. This model is just a bad and misleading metaphor as everybody will agree when consciously considering the issue. Nonetheless, or so I claim, the metaphor is at work in the background of people's mind. If we assume that a philosopher is either him? or herself in the grip of that metaphor or implicitly interprets the view he wishes to attack along the lines of that metaphor, then we can see how it may appear obvious to him that the phenomenological insights associated with 'transparency' lead quite naturally to the strong philosophical claims they have been taken to support.1

Abstract: Ambiguous figures pose a problem for representationalists, particularly for representationalists who believe that the content of perceptual experience is non-conceptual (MacPherson in Nous 40(1):82–117, 2006). This is because, in viewing ambiguous figures, subjects have perceptual experiences that differ in phenomenal properties without differing in non-conceptual content. In this paper, I argue that ambiguous figures pose no problem for non-conceptual representationalists. I argue that aspect shifts do not presuppose or require the possession of sophisticated conceptual resources and that, although viewing ambiguous figures often causes a change in phenomenal properties, this change is accompanied by a change in non-conceptual content. I illustrate the case by considering specific examples.
Comment: Specialised further reading on nonconceptual content and representationalism.

Added by: Clotilde Torregrossa, Contributed by: Simon FoktAbstract: Dretske has recently offered a representational theory of perceptual experience - considered as paradigmatic of the qualitative and phenomenal aspects of our mental life. This theory belongs, as do his previous works, to a naturalistic approach to mental representation

Added by: Clotilde Torregrossa, Contributed by: Simon FoktAbstract: Representationalist solutions to the qualia problem are motivated by two fundamental ideas: first, that having an experience consists in tokening a mental representation; second, that all one is aware of in having an experience is the intentional content of that representation. In particular, one is not aware of any intrinsic features of the representational vehicle itself. For example, when you visually experience a red object, you are aware only of the redness of the object, not any redness or red quale of your experience. You are aware of outer red without being aware of inner red. According to the representationalist, the phenomenal character of your experience is just (an element of) the intentional content of your representation. In effect, inner red just is outer red. For her part, the defender of qualia, or anyway the defender of qualia who will figure in the present discussion, grants that experiencing a red object involves mentally representing it, and that when you have such an experience you are aware of its intentional content. But she denies that that intentional content exhausts your awareness. The defender of qualia (call her 'Quale') contends that your mental vehicle is itself mentally or phenomenally red, and that in addition to the outer redness of the object, you are aware of this inner redness, the intrinsic phenomenal character of your representational vehicle. Thus, contra the representationalist (call him 'Rep'), you are not aware of the content of your representation without being aware of its intrinsic features

Added by: Giada FratantonioSummary: In this paper, the author presents the so-called capacity view, namely, the view that "that perceptual states are systematically linked to what they are of in the good case, that is, the case of a successful perception, and thereby provide evidence for what they are of in the good case". The author discusses the main committments of the view and the implications it has when it comes to the justification of our beliefs and the transparency of our mental states.Comment: Good as further reading for a postgraduate course on epistemology of percpetion.

Added by: Andrea BlomqvistAbstract: In discussions of perception and its relation to knowledge, it is common to distinguish what one comes to believe on the basis of perception from the distinctively perceptual basis of one's belief. The distinction can be drawn in terms of propositional contents: there are the contents that a perceiver comes to believe on the basis of her perception, on the one hand; and there are the contents properly attributed to perception itself, on the other. Siegel argues that high-level properties should be attributed to percception itself. That, high-level properties can be the content of perception.Comment: This paper is interesting to consider in the cognition/perception debate, since high-level properties such as being a natural kind, or emotions and intentions, are normally taken to be features of cognition rather than perception. It raises interesting questions about the relationship between concepts, the content of perception and perceptual experience. It would be good in a third year module on perception.

Added by: Andrea Blomqvist, Contributed by: Will HornettSummary: This paper argues that despite the differences between perception and belief, perception involves states that are importantly similar to beliefs: conscious visual experiences. According to the Content View, these experiences have contents in the form of accuracy conditions. The paper develops and defends the Content View, discusses its significance, and argues that contrary to what is often supposed, the Content View is compatible with Naive Realist disjunctivism.Comment: It is a fairly difficult paper because it has some technical sections and her main argument is rather dense. However, it is generally very clearly written, with numerous helpful examples, and a broad discussion of views on contemporary debate on perception. This paper could be used in a senior year or postgraduate course on the philosophy of perception as seminar reading since it is a detailed and controversial discussion of the metaphysics of perception. It has also been central to recent debates. It is is useful to teach alongside Thomas Raliegh's "Phenomenology Without Representation" (2013).
