ABSTRACT Although in recent years Christine Ladd-Franklin has received recognition for her contributions to logic and psychology, her role in late nineteenth- and early twentieth-century philosophy, as well as her relationship with American pragmatism, has yet to be fully appreciated. My goal here is to attempt to better understand Ladd-Franklin’s place in the pragmatist tradition by drawing attention to her work on the nature and unity of the proposition. The question concerning the unity of the proposition (...) – namely, the problem of how to determine what differentiates a mere collection of terms from a unified and meaningful proposition – received substantial attention in Ladd-Franklin’s time, and would continue to interest analytic philosophers well into the twentieth century. I argue that Ladd-Franklin had a distinct theory of the proposition and solution to the problem of the unity of the proposition that she developed over the course of her writings on logic and philosophy. In spelling out her views, I will also show her work interacted with and influenced that of the pragmatist who was her greatest influence, C.S. Peirce. (shrink)

What is the relationship between unconscious and conscious intentionality? Contemporary philosophy of mind treats the contents of conscious 10 intentional mental states as the same kind of thing as the contents of un- conscious mental states. According to the standard view that beliefs and desires are propositional attitudes, for example, the contents of these states are propositions, whether or not the states are conscious or unconscious. I dispute this way of thinking of conscious and unconscious content, and propose an alternative, (...) which helps to explain why the various mental things that are called unconscious deserve that label.

My general worry is that Schellenberg’s arguments against naive realism, generalism, and Russellian representationalism do not seem to be successful. Thus her attempt at ruling these views out fails. Her main arguments rely on a shared premise whose plausibility, in the absence of an appropriate theory of particulars, is hard to assess (§2.1). Apart from that, these arguments rely on an under-specified notion of constitution; there seems to be no sense of the term that makes all the premises of her (...) major arguments true without trivializing their conclusions (§2.2). It also seems to me that the challenges that Schellenberg raises for her Russellian opponents, or similar problems, arise for her own view (§3). Finally, Schellenberg believes that an advantage of her view is that it entails the possibility of seeing an object without seeing it as being a certain way. In §4, I argue that it is hard to imagine how one could see without seeing as. (shrink)

In recent work, Scott Soames (2010, 2013, 2015, 2019) and Peter Hanks (2011, 2013, 2015) have developed a theory of propositions on which these are constituted by complexes of intellectual acts. In this article, I adapt this type of theory to provide an account of perceptual content. After introducing terminology in section 1, I detail the approach proffered by Soames and Hanks in section 2, focusing on Hanks’s version. In section 3, I introduce a problem that these theories face, namely, (...) how to account for the unity among the relevant intellectual acts. Section 4 provides an answer to this problem of unity, while section 5 explicates the relation to Soames and Hanks. In section 6, I extend the model to a theory of the unity of experiential consciousness. Finally, in section 7, I apply the preceding considerations to debates about the nature of perceptual representation. The upshot will be that experiential unity is not simply a phenomenal feature of consciousness, but central to an account of the role perceptual representation plays in perceptual cognition.

The focus of this paper is Cassirer’s Neo-Kantian reading of Kant’s conception of unity of space. Cassirer’s neo-Kantian reading is largely in conformity with the mainstream of intellectualist Kant-scholars, which is unsurprising, given his own intellectualist view of space and perception and his rejection of the existence of a ‘merely sensory consciousness’ as a ‘formless mass of impression’. I argue against Cassirer’s reading by relying on a Kantian distinction first recognized by Heinrich Rickert, a neo-Kantian from the Southwest school, (...) between Kenntnis (roughly knowledge by acquaintance) and Erkenntnis (roughly propositional knowledge). Correspondingly, I claim that concepts and categories are conditions for Erkenntnis of objects as such, namely for thinking of and apprehending the pre-existing unity as an object, rather than for the ‘constitution’ of this very unity.

[This is an old version which is superseded by the published version. I keep it here for the record, as it has been cited.] A strict dichotomy between the force / mode of speech acts and intentional states and their propositional content has been a central feature of analytical philosophy of language and mind since the time of Gottlob Frege and Bertrand Russell. Recently this dichotomy has been questioned by philosophers such as Peter Hanks (2015, 2016) and Francois Recanati (2016), (...) who argue that we can't account for propositional unity independently of the forceful acts of speakers and propose new ways of responding to the notorious 'Frege point' by appealing to a notion of force cancellation. In my paper I will offer some supplementary criticisms of the traditional view, but also a way of reconceptualizing the force-content distinction which allows us to preserve certain of its features, and an alternative response to the Frege point that rejects the notion of force cancellation in favor of an appeal to intentional acts that create additional forms of unity at higher levels of intentional organization: acts such as questioning a statement or order, or merely putting it forward or entertaining it; pretending to state or order; or conjoining or disjoining statements or orders. This allows us to understand how we can present a forceful act without being committed to it. In contrast, the Frege point confuses a lack of commitment to with a lack of commitment or force in what is put forward. (shrink)

This paper offers a critique of an account of explanatory integration that claims that explanations of cognitive capacities by functional analyses and mechanistic explanations can be seamlessly integrated. It is shown that achieving such explanatory integration requires that the terms designating cognitive capacities in the two forms of explanation are stable but that experimental practice in the mind-brain sciences currently is not directed at achieving such stability. A positive proposal for changing experimental practice so as to promote such stability is (...) put forward and its implications for explanatory integration are briefly considered. (shrink)

Bertrand Russell was neither the first nor the last philosopher to engage in serious theorizing about propositions. But his work between 1903, when he published The Principles of Mathematics, and 1919, when his final lectures on logical atomism were published, remains among the most important on the subject. And its importance is not merely historical. Russell’s rapidly evolving treatment of propositions during this period was driven by his engagement with – and discovery of – puzzles that either continue to shape (...) contemporary theorizing about propositions, or ought to do so. Russell’s creative responses to these puzzles also laid the foundation for many later accounts (most obviously, contemporary ‘Russellian’ accounts of propositions). In this entry we provide an opinionated overview of Russell’s influential treatment of propositions, with a focus on the evolution of his views from 1903 to 1919. A growing secondary literature is dedicated to Russell’s changing views during this period, and their often complex or opaque motivations. We do not intervene overmuch in this ongoing scholarly discussion. Instead, our aim is to trace some of the central motivations for Russell’s evolving views, and highlight the extent to which these motivations remain relevant to contemporary theorizing about propositions.

Several philosophers advance substantive theories of propositions, to deal with several issues they raise in connection with a concern with a long pedigree in philosophy, the problem of the unity of propositions. The qualification ‘substantive’ is meant to contrast with ‘minimal’ or ‘deflationary’ – roughly, views that reject that propositions have a hidden nature, worth investigating. Substantive views appear to create spurious problems by characterizing propositions in ways that make them unfit to perform their theoretical jobs. I will present (...) in this light some critical points against Hanks’ (2015, 2019) act-theoretic view, and Recanati’s (2019) recent elaboration of Hanks’ notion of cancellation. Both Hanks and Recanati, I’ll argue, rely on problematic conceptions of fiction and pretense. (shrink)

This paper argues that attitudinal objects, entities of the sort of John's judgment, John's thought, and John's claim, should play the role of propositions, as the cognitive products of cognitive acts, not the acts themselves.

Philosophers of the modern period are often presented as having made an elementary error: that of confounding the attitude one adopts toward a proposition with its content. By examining the works of Locke and the Port-Royalians, I show that this accusation is ill-founded and that Locke, in particular, has the resources to construct a theory of propositional attitudes.

In this paper I propose three steps to overcome the force-content dichotomy and dispel the Frege point. First, we should ascribe content to force indicators. Through basic assertoric and directive force indicators such as intonation, word order and mood, a subject presents its position of theoretical or practical knowledge of a state of affairs as a fact, as something that is the case, or as a goal, as something to do. Force indicators do not operate on truth- or satisfaction evaluable (...) entities as on the traditional view, but complete and unify them. Second, higher-level acts such as interrogative, logical and fictional acts create higher-level unities that may suspend commitment to the assertions and directions they operate on. But they do not cancel their force, but transfer the meaning of force indicators into the new unities they create. For example, in the context of asking a theoretical or practical question, the assertoric or directive force indicator now presents the kind of knowledge the subject is seeking. Third, the Frege point conflates different varieties of force. We neither need Frege’s assertion sign, nor Hare’s neustic, nor Hanks’s cancellation sign, but only ordinary force indicators and interrogative, logical and fictional markers. Propositions are not forceless contents to which a subject commits by forceful acts, but forceful acts put forward by higher-level acts which may suspend commitment to them. (shrink)

Propositions represent the entities from which they are formed. This fact has puzzled philosophers and some have put forward radical proposals in order to explain it. This paper develops a primitivist account of the representational properties of propositions that centers on the operation of application. As we will see, this theory wins out over its competitors on grounds of strength, systematicity and unifying power.

Each of the degenerating constitutions in Book VIII of Plato's Republic is the result of the disappearance of one of the four cardinal virtues. The failure of wisdom creates a timocracy; the failure of courage, an oligarchy; the failure of moderation, a democracy; the failure of justice, a tyranny. The degeneration shows that the disunited virtues are imperfect, though they have some power to stave off vice. Thus Book VIII implies a unity of the virtues thesis according to which (...) perfect virtues can only exist in a united state, but imperfect simulacra of virtue can exist in a disunited state. -/- Published 2011 in Apeiron: A Journal for Ancient Philosophy and Science.

Franz Brentano’s works are not just full of deep and innovative insights into mind, world and values. His views also turned out to be highly influential upon several generations of students, who made them the basis of their own philosophical investigations, giving rise to what is known as the Brentano School (Albertazzi et al. 1996; Fisette & Fréchette 2007). In this chapter, I give a bird’s eye view of the Brentano School from a rather historical perspective. My leading hypothesis is (...) that one crucial factor explaining the rise of the school is Brentano’s unique strategy, within the academic context of the time, to promote the revival of philosophy as a rigorous science. After a brief introduction, I reconstruct the three main phases in the school’s development, namely Brentano’s teaching in Würzburg (1866-73), his teaching in Vienna (1874-95), and Anton Marty’s teaching in Prague (1880-1913).

This essay argues that Plato in the Republic needs an account of why and how the three distinct parts of the soul are parts of one soul, and it draws on the Phaedrus and Gorgias to develop an account of compositional unity that fits what is said in the Republic.

The paradox of the concept horse has often been taken to be devastating for Frege’s ontological distinction between objects and concepts. I argue that if we consider how the concept-object distinction is supposed to account for the unity of linguistic meaning, it transpires that the paradox is in fact not paradoxical.

In the following article I intend to examine the problem of the unity of the proposition in Russell, Frege, and Wittgenstein. My chief aim will be to draw attention to the distinction between Russell’s conception of propositional constituents, on the one hand, with Frege and Wittgenstein’s on the other. My focus will be on Russell’s view of terms as independent, propositions being built up out of these building blocks, compared with Frege and Wittgenstein’s ‘top down’ approach. Furthermore, I (...) will argue that, contra certain other commentators, Frege’s metaphor of saturation and unsaturation does not serve as a solution to the problem of unity, and that the extension of this metaphorical language to Wittgenstein is, therefore, inappropriate.

In this paper, I advance a new interpretation of the argumentative structure of the third Critique, which in turn clarifies the connection between its two apparently unrelated parts. I propose to read the third Critique as a response to Kant’s question of hope, which concerns the satisfaction of reason’s practical and theoretical interests. On this proposal, while the first part on aesthetics describes what we—as possessors of theoretical reason – may hope for, the second part, on teleology, describes what we (...) – as possessors of practical reason – may hope for. The main question of the third Critique is, ‘What may we hope if we act as we should, i.e. act rationally?’ Kant’s implicit answer is, ‘to attain the ideals of reason, which leads to happiness as a consequence of it.’ This novel reconstruction of the argumentative structure of the third Critique contributes to the literature by (i) explaining how the two parts of the third Critique on aesthetics and teleology are connected, (ii) clarifying how the ideals of reason are connected to hope and happiness, and (iii) showing how the spheres of nature and freedom can be synthetically unified through the faculty of judgment.

In this paper I pursue an avenue of argument implicit in Patristic thinkers — such as Tertullian and Athanasius — and explicit in the thomistic and scholastic tradition. I argue that there is an ontological unity to the world, and that this unity calls for an explanation in terms of a transcendent cause, traditionally identified with God.

In De Anima 2.4, Aristotle claims that nutritive soul encompasses two distinct biological functions: nutrition and reproduction. We challenge a pervasive interpretation which posits ‘nutrients’ as the correlative object of the nutritive capacity. Instead, the shared object of nutrition and reproduction is that which is nourished and reproduced: the ensouled body, qua ensouled. Both functions aim at preserving this object, and thus at preserving the form, life, and being of the individual organism. In each case, we show how Aristotle’s detailed (...) biological analysis supports this ontological argument. (shrink)

Russell discovered the classes version of Russell's Paradox in spring 1901, and the predicates version near the same time. There is a problem, however, in dating the discovery of the propositional functions version. In 1906, Russell claimed he discovered it after May 1903, but this conflicts with the widespread belief that the functions version appears in _The Principles of Mathematics_, finished in late 1902. I argue that Russell's dating was accurate, and that the functions version does not appear in the (...) _Principles_. I distinguish the functions and predicates versions, give a novel reading of the _Principles_, section 85, as a paradox dealing with what Russell calls _assertions_, and show that Russell's logical notation in 1902 had no way of even formulating the functions version. The propositional functions version had its origins in the summer of 1903, soon after Russell's notation had changed in such a way as to make a formulation possible. (shrink)

Propositions are the things we believe, intend, desire, and so on, but discussions are often less precise than they could be and an important driver of this deficiency has been a focus on the objects but a neglect of the attitudinal relations we bear to them. In what follows, we will offer some thoughts on what it means for a proposition to be the object of an attitude and we will argue that an important part of the story lies (...) with the attitude relations rather than the propositions. As we will see there are infinitely many relations we might bear to a proposition, but the propositional attitude relations are special amongst them. Accounting for what makes them special will be an important component in the discussion that follows. We will argue that once one appreciates certain facts about propositional attitude relations, various claims that metaphysicians often make regarding propositions themselves begin to look undermotivated. In fact, many views on the metaphysical nature of propositions come to look like plausible candidates for being that to which our propositional attitudes relate us. As will emerge, we will see that the principle role of propositions in the theory of mind is simply to keep track of how our attitudinal states represent things as being. But, we argue, in order to do this work, very few constraints must be placed on the nature of propositions themselves. In particular, contra much of the recent work on the metaphysics of propositions, they need not represent nor must they be structured. In light of these observations, we conclude by sketching our own favored minimalist view of propositions. (shrink)

This book has been written for eighteen year olds (or anyone who will listen) as an honest attempt to face their justified questionings and to offer them a metaphysical framework with which to confront the twenty-first century. It is vitally important that certain modes of thought are uprooted and new modes put in their place if mankind and planet Earth are not soon to suffer an historic global catastrophe. Apart from the continuing world-wide proliferation of conventional, chemical, biological and nuclear (...) weaponry, the temperature of the planet has risen more rapidly in the last twenty-five years than it has since the year 900AD, which confirms global warming by some cause or other. These and the many intensifying human conflicts and natural disasters demand that some fundamental changes to our thinking are made as soon as possible. These 120 pages begin with an original examination of the quantum-theoretical understanding of reason (logic) and reality (existence) and find both to be at odds with common sense. A theory of everything is a reduction to a single grand idea! A quantum theory of everything is a mathematical theory of a consciousness realizing this grand idea! That is what this book tries to comprehend by means of five indisputable propositions. (shrink)

Commentators have neglected a tension in Descartes’s virtue theory. In some texts, Descartes seems to argue that there are distinct virtues. In other texts, Descartes seems to argue that there is only a single virtue—the firm and constant resolution to use the will well. In this paper, I reconcile this tension. I argue that Descartes endorses a specific version of the unity of the virtues thesis, namely, the identity of the virtues. Nonetheless, Descartes has the resources to draw conceptual (...) distinctions between various virtues. Distinct virtues are conceptually generated when we regard the firm and constant resolution to use the will well in different ways, that is, based on the different ways this resolution manifests in moral situations.

Critical notice of Richard Gaskin's "The Unity of the Proposition" (OUP 2008).

I respond to Karin de Boer, Thomas Land, and Claudio La Rocca’s comments on Kant’s Critique of Pure Reason and the Method of Metaphysics (CUP 2023). I first provide a quick outline of some of the main claims I make in the book. I then directly address their criticisms, which I group into three categories. The first group of comments raises doubts concerning my characterization of the central tasks of the critique of pure reason. The second targets the fact that (...) I downplay faculty analysis as an essential characteristic of the critique. The third has to do with my claim that the Critique of Pure Reason aims to show that metaphysics is capable of architectonic unity, where this unity is only achievable when we construe metaphysics according to the worldly concept of philosophy.

In he Problems of Philosophy and other works of the same period, Russell claims that every proposition must contain at least one universal. Even fully general propositions of logic are claimed to contain “abstract logical universals”, and our knowledge of logical truths claimed to be a species of a priori knowledge of universals. However, these views are in considerable tension with Russell’s own philosophy of logic and mathematics as presented in Principia Mathematica. Universals generally are qualities and relations, but (...) if, for example, PM’s disjunction (∨) is a relation, what is it a relation between? There is no obvious answer to this given Russell’s other philosophical commitments at this time, although hints are left in some of the pre-PM manuscripts. In this paper, I explore this tension in Russell's philosophy and relate it to developments both before and after Problems. (shrink)

opinionated review of some of the recent work on the phenomenal unity of consciousness.

In _Leviathan_, Hobbes embraces three seemingly inconsistent claims: (i) the unity of a multitude is secured only by the unity of its representer, (ii) assemblies can represent other multitudes, and (iii) assemblies are, or are constituted by, multitudes. Together these claims require that a representative assembly, itself, be represented. If that representer is another assembly, it too will need a unifying representer, and so on. To stop a regress, we will need an already unified representer. But a multitude (...) can only speak or act through its representer, and an assembly is a multitude, so any representing done by the assembly is actually done by this already unified, regress-stopping representer. That is, if (i) and (iii) are true, (ii) cannot be. I will argue that this inconsistency is only apparent and that we can resolve it without rejecting any of these three claims. We do this by appealing to a representer-as-decision-procedure meeting certain criteria. Such a procedural representer breaks the transitivity of representation such that the assembly it represents can properly represent some further multitude. I proceed in my defense of the procedural representer view by addressing a series of problems it faces, the solutions to which give us a progressively clearer picture of the criteria this representer must meet.

In the Phaedrus, Socrates insists that every proper logos must have the unity of an organic living thing. And yet it is hard to say what imposes any such unity on the various speeches and topics that are dealt with in this very dialogue. This chapter situates the view of Hermias of Alexandria in relation to modern debates about what, if anything, unifies the Phaedrus. For the ancient Neoplatonists, the question of unity was bound up with the (...) question of each dialogue's "skopos". We argue that Hermias' answer to this question -- that the skopos of the Phaedrus is 'beauty at every level' -- is not as wildly implausible as Neoplatonic readings of Plato's dialogues are often thought to be.

The unity of consciousness has so far been studied only as a relation holding among the many experiences of a single subject. I investigate whether this relation could hold between the experiences of distinct subjects, considering three major arguments against the possibility of such ‘between-subjects unity’. The first argument, based on the popular idea that unity implies subsumption by a composite experience, can be deflected by allowing for limited forms of ‘experience-sharing’, in which the same token experience (...) belongs to more than one subject. The second argument, based on the phenomenological claim that unified experiences have interdependent phenomenal characters, I show to rest on an equivocation. Finally, the third argument accuses between-subjects unity of being unimaginable, or more broadly a formal possibility corresponding to nothing we can make sense of. I argue that the familiar experience of perceptual co-presentation gives us an adequate phenomenological grasp on what between-subjects unity might be like. (shrink)

According to conventional wisdom, the split-brain syndrome puts paid to the thesis that consciousness is necessarily unified. The aim of this paper is to challenge that view. I argue both that disunity models of the split-brain are highly problematic, and that there is much to recommend a model of the split-brain—the switch model—according to which split-brain patients retain a fully unified consciousness at all times. Although the task of examining the unity of consciousness through the lens of the split-brain (...) syndrome is not a new one—such projects date back to Nagel’s seminal paper on the topic—the time is ripe for a re-evaluation of the issues.

Plato argues that four political arts—politics, kingship, slaveholding, and household-management—are the same. His argument, which prompted Aristotle’s reply in Politics I, has been universally panned. The problem is that the argument clearly identifies household-management with slaveholding, and household-management with politics, but does not fully identify kingship with any of the others. I consider and reject three ways of saving the argument, and argue for a fourth. On my view, Plato assumes that politics is identical with kingship, just as he does (...) elsewhere, but he begs no questions because the point of his argument is to identify the public arts of politics and kingship with the private arts of household-management and slaveholding. He does this successfully by answering three reasons why one might distinguish the private from the public arts. His argument leaves room for Aristotle to propose other reasons. One of them—involving differences among men and women and slaves—is unfortunate, but another is more promising. The Aristotelian can assume that political expertise is a matter of know-how gathered by experience of the particular actions which differ in the public and private arts. But Plato might well be right to reject this, and to insist that the essential difference between the expert and non-expert—the dividing line between good and bad rule—is not in experience but in their grasp of their goals.

I argue—contra moderate grounding pluralists such as Kit Fine and more extreme grounding pluralists such as Jessica Wilson—that there is fundamentally only one grounding/in-virtue-of relation. I also argue that this single relation is indispensable for normative theorizing—that we can’t make sense of, for example, the debate over consequentialism without it. It follows from what I argue that there is no metaethically-pure normative ethics.

Descriptive accounts of the nature of explanation in neuroscience and the global goals of such explanation have recently proliferated in the philosophy of neuroscience and with them new understandings of the experimental practices of neuroscientists have emerged. In this paper, I consider two models of such practices; one that takes them to be reductive; another that takes them to be integrative. I investigate those areas of the neuroscience of learning and memory from which the examples used to substantiate these models (...) are culled, and argue that the multiplicity of experimental protocols used in these research areas presents specific challenges for both models. In my view, these challenges have been overlooked largely because philosophers have hitherto failed to pay sufficient attention to fundamental features of experimental practice. I demonstrate that when we do pay attention to such features, evidence for reduction and integrative unity in neuroscience is simply not borne out. I end by suggesting some new directions for the philosophy of neuroscience that pertain to taking a closer look at the nature of neuroscientific experiments. (shrink)

Marx says of alienated labor that it does not "belong" to the worker, that it issues in a product that does not belong to her, and that it is unfulfilling, unfree, egoistically motivated, and inhuman. He seems to think, moreover, that the first of these features grounds all the others. All of these features seem quite independent, however: they can come apart; they share no obvious common cause or explanation; and if they often occur together this seems accidental. It is (...) not clear, then, how Marx's concept of alienated labor could possess the strong unity which he takes it to have. I defend a reinterpretation of the concept which explains this unity. The various features of alienated labor, I argue, all follow from a single, hitherto underappreciated feature of its formal motivational structure: the fact that such labor is motivated not by its product but by an incentive.

Writers in the propositions literature consider the Benacerraf objection serious, often decisive. The objection figures heavily in dismissing standard theories of propositions of the past, notably set-theoretic theories. I argue that the situation is more complicated. After explicating the propositional Benacerraf problem, I focus on a classic set-theoretic theory of propositions, the possible worlds theory, and argue that methodological considerations influence the objection’s success.

Cases of reasonable, mistaken belief figure prominently in discussions of the knowledge norm of assertion and practical reason as putative counterexamples to these norms. These cases are supposed to show that the knowledge norm is too demanding and that some weaker norm ought to put in its place. These cases don't show what they're intended to. When you assert something false or treat some falsehood as if it's a reason for action, you might deserve an excuse. You often don't deserve (...) even that. (shrink)

Suárez held that the vital faculties of the soul are really distinct from the soul itself and each other and that they cannot causally interact. This means that he needed to account for the connections between the activities of the faculties: they both interfere with and contribute to each other’s activities. Suárez does so by giving the soul a direct causal role in these activities. This role requires the unity of the soul of a living being and Suárez used (...) it to argue against the view that a living being, in particular a human being, has more than one soul. This line of thought displays some affinity with arguments for the simplicity of the soul from the unity of consciousness. One important difference is that Suárez was talking not just about mental activities but about all vital activities. (shrink)

Naïve Realists hold that perceptual experience is a conscious relation to an object and its property-instances. In contrast, Representationalists hold that it is a conscious representational state with content, something which is accurate or inaccurate in certain conditions. The most common versions of Representationalism take perceptual content to be either general (Generalism) or singular in the object-place and otherwise consisting of attribution of properties (Singularism/Attributionism). Susanna Schellenberg has recently developed a version on which perceptual content is singular even in the (...) property-place in containing a de re mode of presentation of a property-instance (Particularism) (Schellenberg 2018). Particularism is explicitly motivated by its ability to capture certain Naïve Realist insights and it would be genuine progress if it were the best version of Representationalism. Then the debate between Naïve Realism and Representationalism would reduce to the debate over Disjunctivism. In this paper I show that Particularism faces a version of the problem of the Unity of Perceptual Content. Namely, its supporters haven’t told us how objects can be bound together with property-instances into a content such that it represents them and has accuracy-conditions. Furthermore, I argue that Particularists face an in-principle obstacle in solving it. In contrast, Attributionists can say that objects are bound together with properties into a content because the latter are attributed to the former. This establishes Attributionism as the only Representationalist game in town. But Attributionism can’t capture all Naïve Realist insights that the Particularists are after. Thus, the debate between Naïve Realism and Representationalism doesn’t reduce to the debate over Disjunctivism. (shrink)

Henry More argues that materialism cannot account for cases where a single subject or perceiver has multiple perceptions simultaneously. Since we clearly do have multiple perceptions at the same time--for example, when we see, hear, and smell simultaneously--More concludes that we are not wholly material. In response to More's argument, Margaret Cavendish adopts a two-fold strategy. First, she argues that there is no general obstacle to mental unification in her version of materialism. Second, Cavendish appeals to the mind or rational (...) matter--terms she often uses interchangeably—to explain the integration of sensory input from multiple senses. When the mind integrates perceptions across modalities, the different parts of rational matter share their knowledge so that they all come to perceive alike. When rational parts successfully communicate their knowledge, each part knows what all the others know. They pool their knowledge; they perceive alike. Thus, when someone hears, sees, and tastes, each part of her mind hears, sees, and tastes alike, in parallel and in unison. The Cavendishian mind, in short, approximates simplicity by achieving uniformity or homogeneity of perceptions across its parts. (shrink)

I argue that using information from a cognitive representation to guide the performance of a primary task is sufficient for intellectual attention, and that this account of attention is endorsed by scientists working in the refreshing, n-back, and retro-cue paradigms. I build on the work of Wayne Wu, who developed a similarly motivated account, but for perceptual attention rather than intellectual attention. The way that I build on Wu’s account provides a principled way of responding to Watzl’s challenge to Wu, (...) according to which Wu’s style of account is unintuitively broad. The fact that I find unity in the practice of science puts us in a position to resist the claim that scientists studying intellectual attention are frequently failing to study the same thing.

My primary aim in this article is to provide a philosophical account of the unity of hallucinations, which can capture both perceptual hallucinations (which are subjectively indistinguishable from perceptions) and non-perceptual hallucinations (all others). Besides, I also mean to clarify further the division of labour and the nature of the collaboration between philosophy and the cognitive sciences. Assuming that the epistemic conception of hallucinations put forward by M. G. F. Martin and others is largely on the right track, I (...) will focus on two main tasks: (a) to provide a satisfactory phenomenology of the subjective character of perceptions and perceptual hallucinations and (b) to redress the philosophers’ neglect of non-perceptual hallucinations. More specifically, I intend to apply one of the central tenets of the epistemic conception—that hallucinations can and should be positively characterised in terms of their phenomenological connections to perceptions—to non-perceptual hallucinations as well. That is, I will try to show that we can positively specify the class of non-perceptual hallucinations by reference to the distinctive ways in which we first-personally experience them and perceptions in consciousness. The task of saying more about their underlying third-personal nature may then be left to the cognitive sciences. (shrink)

I argue that Kant’s distinction between the cognitive roles of sensibility and understanding raises a question concerning the conditions necessary for objective representation. I distinguish two opposing interpretive positions—viz. Intellectualism and Sensibilism. According to Intellectualism all objective representation depends, at least in part, on the unifying synthetic activity of the mind. In contrast, Sensibilism argues that at least some forms of objective representation, specifically intuitions, do not require synthesis. I argue that there are deep reasons for thinking that Intellectualism is (...) incompatible with Kant's view as expressed in the Transcendental Aesthetic. We can better see how Kant’s arguments in the first Critique may be integrated, I suggest, by examining his notion of the 'unity' [Einheit] of a representation. I articulate two distinct ways in which a representation may possess unity and claim that we can use these notions to integrate Kant’s arguments in the Aesthetic and the Transcendental Deduction without compromising the core claims of either Sensibilism or Intellectualism—that intuition is a form of objective representation independent of synthesis, and that the kind of objective representations that ground scientific knowledge of the world require synthesis by the categories.
