In recent discussions of two important issues in the philosophy of perception, viz. the problems of perceptual presence and perceptual constancy, Merleau-Ponty’s ideas have been garnering attention thanks to the work of Sean Kelly and Alva Noë. Although both Kelly’s normative approach and Noë’s enactive approach highlight important aspects of Merleau-Ponty’s view, I argue that neither does full justice to it because they overlook the central role that style plays in his solution to these problems. I show that a closer (...) look at the Phenomenology and several other texts from this period reveals that, on Merleau-Ponty’s account, we are able to perceive the absent features of objects as present, constant properties, and constant objects because we recognize that the objects we perceive have a unique style that persists through and unifies all their appearances.

John McDowell has recently changed his line of response to philosophical scepticism about the external world. He now claims to be in a position to use the strategy of transcendental argumentation in order to show the falsity of the sceptic’s misrepresentation of our ordinary epistemic standpoint. Since this transcendental argument begins from a weak and widely shared assumption shared with the sceptic herself the falsity of external world scepticism is now demonstrable even to her. Building on the account of perceptual (...) intentionality defended in the Woodbridge lectures, McDowell argues that the idea of narrow perceptual content is unavailable to anyone, including the sceptic. This argument is assessed by drawing out an analogy with parallel responses to error theories in ethics. (shrink)

This paper introduces a novel conceptualisation of mental imagery; namely, that is grease for the mind’s gears (MGT). MGT is not just a metaphor. Rather, it describes an important and overlooked higher-order function of mental imagery: that it aids various mental faculties discharge their characteristic functional roles. MGT is motivated by reflection on converging evidence from clinical, experimental and social psychology and solves at least two neglected conceptual puzzles about mental imagery. The first puzzle concerns imagery’s architectural promiscuity; that is, (...) its ability to assist diverse mental faculties and perform many different functions when doing so. The second puzzle concerns how to square imagery’s architectural promiscuity with its psychopathological relevance; that is, its being a maintaining cause, and possibly even a partial constituent, of several psychological disorders, including post-traumatic stress disorder, bipolar disorder and major depressive disorder. Mental imagery helps and harms human psychology to extreme degrees and this is something that calls for elucidation. MGT says that instead of facing perplexing heterogeneities here, we instead face a significant unity. On this score, MGT is argued to be superior to the currently dominant conception of imagery in the philosophical literature; namely, as a perception-like state of mind. (shrink)

Dass wir alle in einer gemeinsamen Wirklichkeit leben, setzen wir meist unhinterfragt voraus. Sehen Andere die Welt dann doch einmal anders, mag es uns scheinen, als sähen sie diese einfach nicht so, wie sie wirklich ist. Schwerer fällt uns anzuerkennen, dass andere zuweilen in ganz anderen Wirklichkeiten unterwegs sind als wir selbst. - Tom Poljansek zeigt, wie sich die Vorstellung einer Pluralität menschlicher Wirklichkeiten mit der Annahme einer wahrnehmungsunabhängigen Realität vereinbaren lässt, ohne sich in einen Relativismus der vielen Wirklichkeiten zu (...) verlaufen. In Auseinandersetzung mit »kontinentalen« und »analytischen« Ansätzen legt er eine elegante Theorie menschlicher Wirklichkeiten vor, die konstruktivistische und realistische, phänomenologische und naturalistische Motive unerwartet miteinander verbindet.

Predictive processing (PP) accounts of perception are unique not merely in that they postulate a unity between perception and imagination. Rather, they are unique in claiming that perception should be conceptualised in terms of imagination and that the two involve an identity of neural implementation. This paper argues against this postulated unity, on both conceptual and empirical grounds. Conceptually, the manner in which PP theorists link perception and imagination belies an impoverished account of imagery as cloistered from the external world (...) in its intentionality, akin to a virtual reality, as well as endogenously generated. Yet this ignores a whole class of imagery whose intentionality is directed on the actual environment—projected mental imagery—and also ignores the fact that imagery may be triggered crossmodally in a bottom-up, stimulus-driven way. Empirically, claiming that imagery and perception share neural circuitry ignores relevant clinical results in this area. These evidence substantial perception/imagery neural dissociations, most notably in the case of aphantasia. Taken together, the arguments here suggest that PP theorists should substantially temper, if not outright abandon, their claim to a perception/imagination unity. (shrink)

What is the relationship between perception and mental imagery? I aim to eliminate an answer that I call perceptualism about mental imagery. Strong perceptualism, defended by Bence Nanay, predictive processing theorists, and several others, claims that imagery is a kind of perceptual state. Weak perceptualism, defended by M. G. F. Martin and Matthew Soteriou, claims that mental imagery is a representation of a perceptual state, a view sometimes called The Dependency Thesis. Strong perceptualism is to be rejected since it misclassifies (...) imagery disorders and abnormalities as perceptual disorders and abnormalities. Weak Perceptualism is to be rejected since it gets wrong the aim and accuracy conditions of a whole class of mental imagery–projected mental imagery–and relies on an impoverished concept of perceptual states, ignoring certain of their structural features. Whatever the relationship between perception and imagery, the perceptualist has it wrong. (shrink)

What triggers the execution of actions? What happens in that moment when an action is triggered? What mental state is there at the moment of action-execution that was not there a second before? My aim is to highlight the importance of a thus far largely ignored kind of mental state in the discussion of these old and much-debated questions: motor imagery. While there have been a fair amount of research in psychology and neuroscience on motor imagery in the last 30 (...) years or so, it is only recently that we start to understand the important role motor imagery plays in action initiation. And if, as these findings suggest, motor imagery plays an important role in action initiation, we can make progress not only in understanding action initiation in general but also in understanding what goes wrong in akratic actions and in relapse actions. Finally, this new picture of action-initiation also has far-reaching consequences for the relation between motivation and causation in naturalistic action-explanations. (shrink)

Sensorimotor expectations concern how visual experience covaries with bodily movement. Sensorimotor theorists argue from such expectations to the conclusion that the phenomenology of vision is constitutively embodied: objects within the visual field are experienced as 3-D because sensorimotor expectations partially constitute our experience of such objects. Critics argue that there are two ways to block the above inference: to explain how we visually experience objects as 3-D, one may appeal to such non-bodily factors as expectations about movements of objects, not (...) the perceiver, or to the role of mental imagery in visual experience. But instead of using sensorimotor expectations to explain how objects are experienced within the visual field, we can instead use them to explain our experience of the visual field itself and, in particular, our experience of its limits; that is, our ever-present visual sense of there being more to see, beyond what’s currently within the visual field. Crucially, this inference from sensorimotor expectations to the constitutive embodiment of visual phenomenology is not threatened by the above two challenges. I thus present here a sensorimotor theory of the phenomenology of the visual field, that is, our experience of our visual fields as such. (shrink)

In this paper, first, I will focus on the divergent interpretations of two leading Sellars’ scholars, Willem deVries and James O’Shea, as regards Sellars’ view on the being of the normative. It will be suggested that this conflict between deVries’ and O’Shea’s viewpoints can be resolved by the provision of an account of what I shall call ‘ready-tohand’ normativity, which incorporates the insights of both deVries’ and O’Shea’s interpretive perspectives, while at the same time going beyond them. It shall be (...) further argued that the resulting ‘phenomenologically’ informed view of normativity, pointing as it does towards its ideal integration not only with practical action but also with perceptual experience, in the form of what I shall call ‘kinaesthetic’ normativity, can potentially pose problems to Sellars’ own view on the matter, and, in particular, to the way normativity can allegedly be ‘stereoscopically fused’ with the ultimate ontology of the ideal scientific image. However, I shall argue that these problems are not unsurpassable: although the possibility of a specifically ‘kinaesthetic’ form of normativity seems to have eluded Sellars’ grasp, his views about the way in which the productive imagination is implicated in perceptual experience, do indeed provide the conceptual resources that make possible the stereoscopic fusion of this kind of normativity with the ontology of the ideal scientific image.
