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.

Worries about mental causation are prominent in contemporary discussions of the mind and human agency. Originally, the problem of mental causation was that of understanding how a mental substance (thought to be immaterial) could interact with a material substance, a body. Most philosophers nowadays repudiate immaterial minds, but the problem of mental causation has not gone away. Instead, focus has shifted to mental properties. How could mental properties be causally relevant to bodily behavior? How could something mental qua mental cause (...) what it does? After looking at the traditional Problem of Interaction, we survey various versions of the property-based problem and look at proposed solutions to them. (shrink)

In recent work Philip Goff has defended the thesis of subjecthood transparency: someone possessing the concept ‘subjecthood’ is thereby in a position to know, a priori, what it is for an entity to be a subject of experiences. Kevin Morris has criticized a specific argument that Goff provides for subjecthood transparency. I will argue that Morris’s criticism of Goff’s argument does not succeed. I will then present an alternative criticism of Goff’s argument, one that also applies to the thesis of (...) subjecthood transparency itself. (shrink)

It is often argued that higher-level special-science properties cannot be causally efficacious since the lower-level physical properties on which they supervene are doing all the causal work. This claim is usually derived from an exclusion principle stating that if a higher-level property F supervenes on a physical property F* that is causally sufficient for a property G, then F cannot cause G. We employ an account of causation as difference-making to show that the truth or falsity of this principle is (...) a contingent matter and derive necessary and sufficient conditions under which a version of it holds. We argue that one important instance of the principle, far from undermining non-reductive physicalism, actually supports the causal autonomy of certain higher-level properties. (shrink)

Stephen Yablo offers a solution to the problem of mental causation by claiming that the physical is a determinate of the mental's determinable, and therefore the mental and physical do not compete for causal relevance. I present Yablo's solution and argue that the mental‐physical relation cannot meet three necessary conditions for determination. That relation fails to meet the requirements that determinates of the same determinable be incompatible and that no property can be a determinate of more than one determinable. Further, (...) the mental and physical do not fall under the same series of scope inclusions as determinables and their determinates must. Yablo's conception of determination might be rendered more general to avoid these objections, but doing so would prevent it from functioning as a competitor to extant theories of the mental‐physical relation. Thus, Yablo's solution to the problem of mental causation cannot be both adequately specific and correct. (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.

Definitions of phenomenal types (Nelson Goodman’s definition of qualia, Sydney Shoemaker’s phenomenal types, Austen Clark’s physicalist theory of qualia) imply that numerically distinct experiences can be type-identical in some sense. However, Goodman also argues that objects cannot be replicated in respect of continuous and densely ordered types. In that case, how can phenomenal types be defined for sizes, shapes and colours, which appear to be continuously ordered types? Concentrating on size, I will argue for the following points. (§2) We cannot (...) deny the possibility of replication in respect of dense types, because this would imply that particulars have determinable sizes, shapes and colours. (§3) Phenomenal sizes and shapes are determinable types; objective, or super-determinate, sizes and shapes are unknowable. (§4) We can define and know, prior to verification, groupings of objective sizes for which indiscriminability is transitive. (§5) Phenomenal identity has to be defined on the basis of these transitive groupings, because finer-grained criteria (such as Goodman’s) lead to definition of objective identity. The quality space of phenomenal types consists of overlapping but not dense types, and this prevents a collapse of phenomenal types. (shrink)

How do we acquire thoughts and beliefs about particulars by looking at pictures? One kind of reply essentially compares depiction to perception, holding that picture-perception is a form of remote object-perception. Lopes’s theory that pictures refer by demonstrative identification, and Walton’s transparency theory for photographs, constitute such remote acquaintance theories of depiction. The main purpose of this paper is to defend an alternative conception of pictures, on which they are not suitable for acquainting us with particulars but for acquainting us (...) with certain kinds of properties. This conception is outlined in §4, where it is argued that pictures are useful devices for what Heal has called indexical predication. In §2 and §3, I explain why I believe that remote acquaintance theories are false, and why picture-perception cannot function as a form of extended or remote object-perception. The main reason is that the contents of picture-perceptions do not themselves provide the kind of numerical and contextual information required for singular thought. Picture-reference is instead secured by independent beliefs or linguistic communication about the causal history of pictures as objects. In other words, it is beliefs about the numerical identity of pictures as objects that anchors the reference of the representational contents of pictures. (shrink)

Degree-sentences, i.e. sentences that seem to refer to things that allow of degrees, are widely used both inside and outside of philosophy, even though the metaphysics of degrees is much of an untrodden field. This paper aims to fill this lacuna by addressing the following four questions: [A] Is there some one thing, such that it is degree sensitive? [B] Are there things x, y, and z that stand in a certain relation to each other, viz. the relation that x (...) has more y than z? [C] In those cases in which degree sentences do not refer to phenomena that are degree sensitive, what is responsible for their prima facie seeming to do so? [D] If there are degree sensitive things, to which ontological categories do they belong? We answer each of these questions by arguing that there are, metaphysically speaking, different phenomena that degree sentences refer to: some refer to determinates that emanate from a certain determinable, others to tokens that are instantiations of a certain type, and yet others to what we call ‘complex, resultant properties that are constituted by stereotypical properties’. Finally, we show the relevance of our answers by applying them to the notions of freedom and belief. (shrink)

In this paper I aim to answer two questions: Can spin be treated as a determinable? Can a treatment of spin as a determinable be used to understand quantum indeterminacy? In response to the first question I show that the relations among spin number, spin components and spin values cannot be captured by a single determination relation; instead we need to look at spin number and spin value separately. In response to the second question I discuss three ways in which (...) the determinables model might be modified to account for indeterminacy, and argue that none of them is fully successful in helping us to understand quantum indeterminacy.

Do component forces exist in conjoined circumstances? Cartwright (1980) says no; Creary (1981) says yes. I'm inclined towards Cartwright's side in this matter, but find several problems with her argumentation. My primary aim here is to present a better, distinctly causal, argument against component forces: very roughly, I argue that the joint posit of component and resultant forces in conjoined circumstances gives rise to a threat of causal overdetermination, avoidance of which best proceeds via eliminativism about component forces. A secondary (...) aim is to show that rejecting component forces does not require, pace Cartwright, rejecting certain attractive theses about what laws of nature express and the role such laws play in scientific explanations.

How can mental properties bring about physical effects, as they seem to do, given that the physical realizers of the mental goings-on are already sufficient to cause these effects? This question gives rise to the problem of mental causation (MC) and its associated threats of causal overdetermination, mental causal exclusion, and mental causal irrelevance. Some (e.g., Cynthia and Graham Macdonald, and Stephen Yablo) have suggested that understanding mental-physical realization in terms of the determinable/determinate relation (henceforth, 'determination') provides the key to (...) solving the problem of MC: if mental properties are determinables of their physical realizers, then (since determinables and determinates are distinct, yet don't causally compete) all three threats may be avoided. Not everyone agrees that determination can do this good work, however. Some (e.g., Douglas Ehring, Eric Funkhauser, and Sven Walter) object that mental-physical realization can't be determination, since such realization lacks one or other characteristic feature of determination. I argue that on a proper understanding of the features of determination key to solving the problem of MC these arguments can be resisted. (shrink)

ABSTRACT Many phenomena appear to be indeterminate, including material macro-object boundaries and certain open future claims. Here I provide an account of indeterminacy in metaphysical, rather than semantic or epistemic, terms. Previous accounts of metaphysical indeterminacy have typically taken this to involve its being indeterminate which of various determinate states of affairs obtain. On my alternative account, MI involves its being determinate that an indeterminate state of affairs obtains. I more specifically suggest that MI involves an object's having a determinable (...) property, but not having any unique determinate of that determinable. I motivate the needed extension of the traditional understanding of determinables, then argue that a determinable-based account of MI accommodates, in illuminating fashion, both ‘glutty’ and ‘gappy’ cases of MI, while satisfactorily treating concerns about MI stemming from Evans’ argument and the problem of the many.

Recent philosophical and empirical contributions strongly suggest that perception attributes determinable properties to its objects. But a characterisation of determinability via attributed properties is restricted to the level of content and does not capture the difference between perceptual belief and perception on this score. In this paper, I propose a formal way of cashing out the difference between determinable belief and perception. On the view presented here, determinability in perception distinctively involves homogeneous representation or representation that exhibits special sorts of (...) formal type variability. This formal characterisation, I suggest, goes beyond traditional approaches to analog representation and parallels a baseline notion of analog computation. (shrink)

Degree‐sentences, i.e. sentences that seem to refer to things that allow of degrees, are widely used both inside and outside of philosophy, even though the metaphysics of degrees is much of an untrodden field. This paper aims to fill this lacuna by addressing the following four questions: [A] Is there some one thing, such that it is degree sensitive?

[D] If there are degree sensitive things, to which ontological categories do they belong? We answer each of these questions by arguing that there are, metaphysically speaking, different phenomena that degree sentences refer to: some refer to determinates that emanate from a certain determinable, others to tokens that are instantiations of a certain type, and yet others to what we call ‘complex, resultant properties that are constituted by stereotypical properties’. Finally, we show the relevance of our answers by applying them to the notions of freedom and belief. (shrink)

The paper begins with a well-known objection to the idea that reasons for action are provided by desires. The objection holds that since desires are based on reasons (first premise), which they transmit but to which they cannot add (second premise), they cannot themselves provide reasons for action. In the paper I investigate an attack that has recently been launched against the first premise of the argument by David Sobel. Sobel invokes a counterexample: hedonic desires, i.e. the likings and dislikings (...) of our present conscious states. The aim of the paper is to defend the premise by bringing the alleged counterexample under its scope. I first point out that reference to hedonic desires as a counterexample presupposes a particular understanding of pleasure, which we might call desire-based. In response, following Sobel, I draw up two alternative accounts, the phenomenological and the tracking views of pleasure. Although Sobel raises several objections to both accounts, I argue in detail that the phenomenological view is not as implausible as he claims it to be, whereas the tracking view, on its best version advocated by Thomas Scanlon, is an instance of the phenomenological view and is therefore also defensible.

The New A-theory of Time is the view, to be elaborated and defended in this article, that many times exist, and that time is real in virtue of every moment in time bearing each of the so-called A-properties: past, present and future. I argue that TNAT is at least as theoretically virtuous as mainstream views in the philosophy of time and may have some claim to being our best theory of time. I show that the properties ‘past’, ‘present’ and ‘future’ (...) can be understood as compatible intrinsic properties. Having demonstrated that this account of the A-properties is coherent, I go on to demonstrate how TNAT can give us an account of passage, change and the truth-conditions for temporal sentences. In the final section of the article, I develop a tentative argument in favour of TNAT, though concede that we have to settle for the result that TNAT is on a par with our other theories of time. In the remainder of this opening section, my aim is to situate the current proposal as a direct response to Mc.. (shrink)

I propose a new argument showing that conscious vision sometimes depends constitutively on conscious attention. I criticise traditional arguments for this constitutive connection, on the basis that they fail adequately to dissociate evidence about visual consciousness from evidence about attention. On the same basis, I criticise Ned Block's recent counterargument that conscious vision is independent of one sort of attention (‘cognitive access'). Block appears to achieve the dissociation only because he underestimates the indeterminacy of visual consciousness. I then appeal to (...) empirical work on the interaction between visual indeterminacy and attention, to argue for the constitutive connection. (shrink)

This possibility supports Stephen Yablo's proportionality (...) principle that the cause of an event is the most specific property that makes a difference. (shrink)

The concept of empathy has received much attention from philosophers and also from both cognitive and social psychologists. It has, however, been given widely conflicting definitions, with some taking it primarily as an epistemological notion and others as a social one. Recently, empathy has been closely associated with the simulationist approach to social cognition and, as such, it might be thought that the concept’s utility stands or falls with that of simulation itself. I suggest that this is a mistake. Approaching (...) the question of what empathy is via the question of what it is for, I claim that empathy plays a distinctive epistemological role: it alone allows us to know how others feel. This is independent of the plausibility of simulationism more generally. With this in view I propose an inclusive definition of empathy, one likely consequence of which is that empathy is not a natural kind. It follows that, pace a number of empathy researchers, certain experimental paradigms tell us not about the nature of empathy but about certain ways in which empathy can be achieved. I end by briefly speculating that empathy, so conceived, may also play a distinctive social role, enabling what I term ‘transparent fellow-feeling’. (shrink)

Are there any disjunctive properties—features of things such as being either red or round, or Nelson Goodman’s infamous example of being grue? As esoteric as the question may seem at first, central issues about the metaphysics of properties hinge upon its answer, such as whether reductive views about special science properties can handle the phenomenon of multiple realizability. A familiar argument for a negative answer is that disjunctive properties fail to guarantee that their instances are similar in some genuine respect. (...) In this paper, I respond to a novel, sophisticated version of this argument developed in recent work by Paul Audi. Along the way, I develop two new accounts of what it is for a property to be disjunctive—which rely on important recent work on the nature of essence and analysis—and clarify what one is committed to in believing that there are any disjunctive properties at all.

Traditional rationalist approaches to a priori epistemology have long been looked upon with suspicion for positing a faculty of rational intuition capable of knowing truths about the world apart from experience. Conceptualists have tried to fill this void with something more empirically tractable, arguing that we know a priori truths due to our understanding of concepts. All of this theorizing, however, has carried on while neglecting an entire cross section of such truths, the grounding claims that we know a priori. (...) Taking a priori grounding into account poses a significant challenge to conceptualist accounts of a priori knowledge, as it is unclear how merely understanding conceptual connections can account for knowledge of grounding. The fact that we do know some grounding truths a priori, then, is a significant mark in traditional rationalism’s favor, and the next frontier for those who aim to eliminate the mystery surrounding a priori knowledge.

In this article, I explain how and why different attempts to defend absolute divine simplicity fail. A proponent of absolute divine simplicity has to explain why different attributions do not suppose a metaphysical complexity in God but just one superproperty, why there is no difference between God and His super-property and finally how a absolute simple entity can be the truthmaker of different intrinsic predications. It does not necessarily lead to a rejection of divine simplicity but it shows that we (...) may consider another conception of divine simplicity compatible with some metaphysical complexity in God.

Faith, broadly construed, is central to the political, social and personal life of any rational agent. I argue for two main claims: first, that a typology of faith based on the fine-grained Indic categories of bhakti, śraddhā, prasāda, abhisaṃpratyaya and abhilāṣa dissolves many of the philosophical problems associated with the nature of faith; second, that this typology of faith has elements that cannot be encompassed in a belief-desire psychology. The upshot is that the structure of the mind is more complicated (...) than belief-desire psychology admits and that understanding the nature of faith has a role to play in charting the structure of the mind.

A fair amount of the philosophical discussion about pain and unpleasantness has focused on providing a constitutive account of unpleasantness. These theories provide a more fundamental description of what unpleasantness is by appealing to other well-established notions in the architecture of the mind. In contrast, I address the nature of unpleasantness from a structural account. I will argue for how unpleasantness is built, rather than what unpleasantness is made of, as it were. I focus on the heterogeneity of experience, which (...) has been a somewhat neglected issue in the literature about unpleasantness: after careful introspection, there seems to be nothing phenomenal that all and only unpleasant experiences share. In order to address the heterogeneity of unpleasant experiences, I propose that the structure of the rich phenomenology of unpleasantness should be understood as a determinable property constituted by multiple essential dimensions.

I erect a framework within the semantic view of theories for explaining the empirical success of internally inconsistent models and theories, with scientific realism in mind. The framework is an instance of the ‘content-driven’ approach to inconsistency, advocated by both Norton (Philos Sci 54:327–350, 1987) and Smith (Stud Hist Philos Sci 19:429–445, 1988a, In: Fine A, Leplin J (eds) PSA1988, 1988b), whose ideas my analysis aims to clarify and substantiate.

A much-discussed idea in the causation literature is that it is preferable to invoke causes which are proportional to—neither too general nor too specific for—the effect. This article presents various ways of understanding this idea. In what sense are such causal claims ‘preferable’? And what is it for one event to be ‘proportional’ to another? In a companion article, ‘Proportionality in Causation, Part II: Applications and Challenges’, I discuss the principal applications of the resulting theories of proportionality, and the challenges (...) they face. (shrink)

Proportionality—the idea that causes are neither too general nor too specific for their effects—seems to recommend implausibly disjunctive causes (McGrath, 1998 ; Shapiro & Sober, 2012 ; Franklin-Hall, 2016 ). I argue that this problem should be avoided by appeal to the notion of cohesion. I propose an account of cohesion in terms of the similarity structure of property-spaces, argue that it is not objectionably mysterious, and that alternative approaches—based on naturalness, interventionism, and contrastivism—are inadequate without appeal to it. In (...) an appendix, I show how my proposal can be perspicuously formalized by adapting structural equation models. (shrink)

I argue that phenomenal externalism is preferable to phenomenal internalism on the basis of externalism's explanatory power with respect to qualitative character. I argue that external qualities, namely, external physical properties that are qualitative independent of consciousness, are necessary to explain qualitative character, and that phenomenal externalism is best understood as accepting external qualities while phenomenal internalism is best understood as rejecting them. I build support for the claim that external qualities are necessary to explain qualitative character on the basis (...) of a model of color perception as a certain sort of information filter by which perceivers gain access to external qualities.

This article considers three views about which properties are genuine. According to the first view, we should look to successful commonsense and scientific explanations in determining which properties are genuine. On this view, predicates that figure in such explanations thereby pick out genuine properties. According to the second view, the only predicates that pick out genuine properties are those that figure in our best scientific explanations. On this view, predicates that figure in commonsense explanations pick out genuine properties only if (...) such explanations are vindicated by the sciences. According to the third view, the only genuine properties are the fundamental, microphysical ones. On this view, although there are “higher-level” predicates that figure in true commonsense and scientific explanations, there are no “higher-level” properties corresponding to such predicates. The article argues that the third view is superior to the others. (shrink)

In this paper, I offer a new theory of grounding. The theory has it that grounding is a job description that is realized by different properties in different contexts. Those properties play the grounding role contingently, and grounding is the property that plays the grounding role essentially. On this theory, grounding is monistic, but ‘grounding’ refers to different relations in different contexts. First, I argue against Kit Fine’s monist univocalism. Next, I argue against Jessica Wilson’s pluralist multivocalism. Finally, I introduce (...) monist multivocalism, explicate three versions of it (of which the above is one), and show its advantages.

The status of genes as bearers of semantic content remains very much in dispute among philosophers of biology. In a series of papers, Nicholas Shea has argued that his ‘infotel’ theory of semantics vindicates the claim that genes carry semantic content. On Shea’s account, each organism is associated with a ‘developmental system’ that takes genetic representations as inputs and produces whole-organism traits as outputs. Moreover, at least in his most recent work on the topic, Shea is explicit in claiming that (...) these genetic representations are ‘read in ontogenetic time, in the course of individual development’. Here I argue that a close examination of the process of reading, in Shea’s sense, reveals that acts of reading do not actually occur over the course of developmental time at all. To make this vivid, I contrast the process of reading for Shea with another type of developmental process that is widely seen as a form of reading directed on inherited genes, and which certainly does occur over the course of developmental time, namely, gene expression. I suggest that this error in Shea’s thinking can be traced back to an equivocation on Shea’s part in the meaning of ‘reads’, and also to a reliance on an invalid principle regarding the transference of representational content from one token gene to another. The issues at play are bound up with questions about causation and in particular about causation over time. Thus, having first presented my arguments in a way that doesn’t depend on any particular theory of causation, I then make use of Kenneth Waters’ framework of difference-making causation to conceptually sharpen and shed further light on matters. I conclude by discussing a consequence of the fact that acts of reading do not occur in development. 1 Introduction2 Reading for Shea3 Gene Expression as Reading4 Are Genetic Representations Read in Development?

According to alethic functionalism, truth is a generic alethic property related to lower level alethic properties through the manifestation relation. The manifestation relation is reflexive; thus, a proposition’s truth-manifesting property may be a lower level property or truth itself, depending on the subject matter properties of the proposition. A true proposition whose truth-manifesting property is truth itself, rather than a lower level alethic property, is plainly true. Alethic functionalism relies on plain truth to account for the truth of propositions with (...) challenging subject matter properties, such as logically complex propositions and truth attributions. In this paper, it is argued that plain truth leads to a number of serious problems for alethic functionalism. First: Shapiro argues that plain truth threatens alethic functionalism with collapse to strong alethic monism; it is argued here that collapse is not merely threatened, but that, on pain of contradiction, collapse is immediate. Second, alethic functionalism’s commitment to alethic pluralism requires lower level alethic properties to be ways of being truth, where one property’s being a way of being the other property is irreflexive; thus, alethic functionalism is incoherent due to the conflicting commitments to a manifestation relation which is both reflexive and irreflexive. Third, it is argued that a reflexive manifestation relation leads to the contradiction that a lower level alethic property which manifests truth is both identical to and distinct from truth itself. Fourth, careful examination of the notion of a core truism shows that Objectivity and the correspondence intuition are the only core truisms. Finally, it is argued that the first and fourth problems jointly entail a collapse of alethic functionalism to strong correspondence monism. (shrink)

Michael Lynch has recently proposed an updated version of alethic functionalism according to which the relation between truth per se and lower-level truth properties is not the realization relation, as might be expected, and as Lynch himself formerly held, but the manifestation relation. I argue that the manifestation relation is merely a resemblance relation and is inadequate to properly relate truth per se to lower-level truth properties. I also argue that alethic functionalism does not justify the claim that truth per (...) se exists, or that truth per se is a functional property. Finally, I suggest a replacement for the manifestation relation. I argue that the resulting theory is a strict improvement over alethic functionalism on two counts, but that the improved theory does not justify the claim that truth per se exists. Since no further improvements to the theory are apparent, the prospects for alethic functionalism are dim. (shrink)

Among the exciting prospects raised by advocates of predictive processing [PP] is the offer of a systematic description of our neural activity suitable for drawing explanatory bridges to the structure of conscious experience. Yet the gulf to cross seems wide. For, as critics of PP have argued, our visual experience certainly doesn’t seem probabilistic.While Clark proposes a means to make PP compatible with the experience of a determinate world, I argue that we should not rush to do so. Two notions (...) of determinacy are conflated in the claim that perception is determinate: ‘univocality’ and ‘full detail’. The former, as Clark argues, is only to be expected in any PP agent that models its world for the purpose of acting on it. But as Husserl argued, and as perceptual psychology has borne out, we significantly overestimate the degree of detail with which we perceive a univocal world.This second form of indeterminacy is due not to the probabilistic nature of PP’s model, but rather to its hierarchical structure, with increasingly coarse-grained representations as we move further from the sensory periphery. A PP system may, or may not, deliver a univocal hypothesis at each of these levels. An action-oriented PP system would only be expected to do so only at the level needed for successful action guidance. A naïve reporter’s overestimation of the degree of determinate detail in their visual experience can thereby be accounted for with a more gradual version of the ‘refrigerator light’ effect: we experience determinate details just to the degree that they’re needed – immediately as they’re needed.

According to a once influential view of selection, it consists of repeated cycles of replication and interaction. It has been argued that this view is wrong: replication is not necessary for evolution by natural selection. I analyze the nine most influential arguments for this claim and defend the replication–interaction conception of selection against these objections. In order to do so, however, the replication–interaction conception of selection needs to be modified significantly. My proposal is that replication is not the copying of (...) an entity, the replicator, but the copying of a property. Thus, we can have a replication process without there being a replicator that is being copied. (shrink)

This paper proposes to carve out a new position in the scientific realism/antirealism debate and argue that it captures some of the most important realist and some of the most important antirealist considerations. The view, briefly stated, is that there is always a fact of the matter about whether the singular statements science gives us are literally true, but there is no fact of the matter about whether the non-singular statements science gives us are literally true. I call this view (...) singularist semirealism. Singularist semirealism sides with scientific realism with regards to singular statements but it is an antirealist view with regards to non-singular statements. In this sense, singularist semirealism could be considered to be ‘the best of both worlds’. 1 Introduction2 Truth and Correctness3 Property-Tokens and Property-Types4 Singularist Semirealism5 Encouragement from Actual Scientific Practice6 Some Potentially Worrying Consequences of Singularist Semirealism7 Some Promising Consequences of Singularist Semirealism8 Conclusion: Theory Change.

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)

The focus of this commentary is what Andy Clark takes to be the most groundbreaking of the philosophical import of the ‘bidirectional hierarchical model of brain functions’, namely, the claim that perceptual representations represent probabilities. This is what makes his account Bayesian and this is a philosophical or theoretical conclusion that neuroscientists and psychologists are also quick and happy to draw. My claim is that nothing in the ‘bidirectional hierarchical models of brain functions’ implies that perceptual representations are probabilistic, or (...) that they represent or ‘encode probability density distributions’. There is a much more parsimonious way of describing the representations in the bidirectional hierarchical model of brain functions: they attribute properties to objects (or to the perceived scene) that are not fully determinate. (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.

I argued in Nanay 2010 that we cannot characterize perceptual content without reference to attention. Here, I defend this account from three objections raised by Jagnow 2011. This mainly takes the form of clarifying some details not sufficiently elaborated in the original article and dispelling some potential misunderstandings.

According to phenomenal transparency, phenomenal concepts are transparent where a transparent concept is one that reveals the nature of that to which it refers. What is the connection between phenomenal transparency and our concept of a subject of experience? This paper focuses on a recent argument, due to Philip Goff, for thinking that phenomenal transparency entails transparency about subjecthood. The argument is premissed on the idea that subjecthood is related to specific phenomenal properties as a determinable of more specific determinates. (...) I argue that the argument fails, which opens the door for one to endorse phenomenal transparency while denying transparency about the concept of a subject of experience. I draw out the consequences of this for certain versions of the combination problem for panpsychist metaphysics and moreover argue that rejecting the transparency of subjecthood does not undermine anti-physicalist arguments premissed on considerations relating to phenomenal transparency.

This paper focuses on an influential line of response to the exclusion problem for nonreductive physicalism, one defended with the most subtlety by Karen Bennett. According to this line of thought, a successful nonreductive response to the exclusion problem, a response that allows one to maintain each of the core components of nonreductive physicalism, may consist in showing that the manner in which the effects of mental causes also have distinct and sufficient physical causes is disanalogous to other types of (...) cases in which an effect may have distinct sufficient causes. After laying out the formulation of the problem that Bennett endorses, along with her response to the problem, I offer an initial critique of this response insofar as it is couched in terms of her preferred formulation. I then present a general critique of disanalogy-style responses to the exclusion problem. I argue that extant implementations of this strategy are at best underdeveloped, and suggest that lack of clarity in the use of “overdetermination” may function to mask the shortcomings of this strategy. While others have questioned the details of such responses, the worries that I raise concern the very logic of the exclusion problem and how such responses fit into this logic. (shrink)

What I call Mellor’s Question is the problem of whether determinables are properties of their determinates or properties of the particulars that possess these determinates. One can distinguish two basic competing theories of determinables that address the issue, implicitly if not explicitly. On the second-order theory, determinables are second-order properties of determinate properties; on the second-level theory, determinables are first-order properties of the particulars with these determinate properties. Higher-order properties are prima facie ontologically uneconomical, and in line with my general (...) view that ontological parsimony is vital to metaphysics, I consider it highly important which of the two theories is true. Firstly, I argue that the second-level theory offers the best explanation of the explananda (though the race is close), including the important but neglected phenomenon of ‘intermediate determinables’. Secondly, by paying attention to intermediate determinables and instantiation of higher-order properties, I argue that the second-level theory also is more ontologically economical. For these two reasons, this theory is preferable. (shrink)
