What is the role of phenomenal consciousness in grounding epistemic justification? This paper explores the prospects for a global version of phenomenal conservatism inspired by the work of Michael Huemer, according to which all epistemic justification is grounded in phenomenal seemings. I’m interested in this view because of its global ambitions: it seeks to explain all epistemic justification in terms of a single epistemic principle, which says that you have epistemic justification to believe whatever seems to you strongly enough on (...) balance to be true. One of the attractions of phenomenal conservatism is that it offers such a simple and unified framework for explaining the epistemic role of phenomenal consciousness. I will argue, however, that the simplicity of phenomenal conservatism is not a theoretical virtue, but a theoretical vice, since it distorts the epistemological phenomena it is supposed to explain. In effect, phenomenal conservatism seeks to explain all epistemic justification on the same model as perception. But this has the predictable effect of distorting the epistemology of other domains, including introspection, inference, and a priori justification. (shrink)

This is the second in a series of two articles that serve as an introduction to recent debates about cognitive phenomenology. Cognitive phenomenology can be defined as the experience that is associated with cognitive activities, such as thinking, reasoning, and understanding. What is at issue in contemporary debates is not the existence of cognitive phenomenology, so defined, but rather its nature and theoretical role. The first article examines questions about the nature of cognitive phenomenology, while the second article explores the (...) philosophical implications of these questions for the role of consciousness in theories of intentionality, introspective self-knowledge, and knowledge of the external world.

In his provocative and engaging new book, Perplexities of Consciousness, Eric Schwitzgebel makes a compelling case that introspection is unreliable in the sense that we are prone to ignorance and error in making introspective judgments about our own conscious experience. My aim in this commentary is to argue that Schwitzgebel’s thesis about the unreliability of introspection does not have the damaging implications that he claims it does for the prospects of a broadly Cartesian approach to epistemology.

Comment on Declan Smithies's book The Epistemic Role of Consciousness (2019).

Which beings have moral status? I argue that moral status requires some capacity for hedonic feelings of pleasure or displeasure. David Chalmers rejects this view on the grounds that it denies moral status to Vulcans, which are defined as conscious creatures with no capacity for hedonic feelings. On his more inclusive view, all conscious beings have moral status. We agree that only conscious beings have moral status, but we disagree about how to explain this. I argue that we cannot explain (...) why consciousness is necessary for moral status without denying that it is sufficient for moral status. Hence, we cannot exclude unconscious zombies without excluding conscious Vulcans too. (shrink)

This chapter argues that attention is a distinctive mode of consciousness, which plays an essential functional role in making information accessible for use in the rational control of thought and action. The main line of argument can be stated quite simply. Attention is what makes information fully accessible for use in the rational control of thought and action. But what makes information fully accessible for use in the rational control of thought and action is a distinctive mode of consciousness. Therefore, (...) attention is a distinctive mode of consciousness. In a slogan: attention is rational-access consciousness. (shrink)

Perception enables us to think demonstrative thoughts about the world around us, but what must perception be like in order to play this role? Does perception enable demonstrative thought only if it is conscious? This paper examines three accounts of the role of consciousness in demonstrative thought, which agree that consciousness is essential for demonstrative thought, but disagree about why it is. First, I consider and reject the accounts proposed by Gareth Evans in The Varieties of Reference and by John (...) Campbell in Reference and Consciousness before offering an alternative proposal of my own. My proposal is that consciousness plays an essential epistemic role in explaining the capacity for demonstrative thought about an object by enabling the subject to form immediately justified beliefs about the object.

In this chapter, I argue for the thesis that phenomenal consciousness is the basis of epistemic justification. More precisely, I argue for the thesis of phenomenal mentalism, according to which epistemic facts about which doxastic attitudes one has justification to hold are determined by non-epistemic facts about one’s phenomenally individuated mental states. I begin by providing intuitive motivations for phenomenal mentalism and then proceed to sketch a more theoretical line of argument according to which phenomenal mentalism provides the best explanation (...) of the independently motivated thesis of access internalism. The result is a theory of epistemic justification that brings intuition and theory into reflective equilibrium. (shrink)

What is the connection between justification and truth in moral epistemology? The primary goal of this paper is to argue that you cannot have justified false beliefs about your own moral obligations. The secondary goal is to explain why not. Some epistemologists embrace a global truth-connection in epistemology, according to which epistemic justification is always factive. In contrast, I endorse a local truth-connection in moral epistemology, which says that epistemic justification is factive when it concerns your own moral obligations. To (...) explain this, I appeal to a version of moral rationalism, which says there are necessary truths about morality that everyone has a priori justification to believe. (shrink)

Could there be a cognitive zombie – that is, a creature with the capacity for cognition, but no capacity for consciousness? Searle argues that there cannot be a cognitive zombie because there cannot be an intentional zombie: on this view, there is a connection between consciousness and cognition that is derived from a more fundamental connection between consciousness and intentionality. However, I argue that there are good empirical reasons for rejecting the proposed connection between consciousness and intentionality. Instead, I argue (...) that there is a connection between consciousness and cognition that is derived from a more fundamental connection between consciousness and rationality. On this view, there cannot be a cognitive zombie because there cannot be a rational zombie. (shrink)

This chapter develops a simple theory of introspection on which a mental state is introspectively accessible just by virtue of the fact that one is in that mental state. This theory raises two questions: first, a generalization question: which mental states are introspectively accessible; and second, an explanatory question: why are some mental states introspectively accessible, rather than others, or none at all? In response to the generalization question, I argue that a mental state is introspectively accessible if and only (...) if it is phenomenally individuated. And in response to the explanatory question, I argue that a mental state is introspectively accessible if and only if it is among the determinants of justification. This provides the basis of an argument for a phenomenal conception of justification, according to which a mental state is among the determinants of justification if and only if it is phenomenally individuated. (shrink)

This chapter is guided by the hypothesis that the point and purpose of using the concept of justification in epistemic evaluation is tied to its role in the practice of critical reflection. In section one, I propose an analysis of justification as the epistemic property in virtue of which a belief has the potential to survive ideal critical reflection. In section two, I use this analysis in arguing for a form of access internalism on which one has justification to believe (...) a proposition if and only if one has higher-order justification to believe that one has justification to believe that proposition. In section three, I distinguish between propositional and doxastic versions of access internalism and argue that the propositional version avoids familiar objections to the doxastic version. In section four, I argue that the propositional version of access internalism also explains and vindicates internalist intuitions about cases. In section five, I conclude with some reflections on the relationship between critical reflection, responsibility and personhood. (shrink)

The aim of this paper is to argue that what I call the simple theory of introspection can be extended to account for our introspective knowledge of what we believe as well as what we consciously experience. In section one, I present the simple theory of introspection and motivate the extension from experience to belief. In section two, I argue that extending the simple theory provides a solution to Moore’s paradox by explaining why believing Moorean conjunctions always involves some degree (...) of irrationality. In section three, I argue that it also solves the puzzle of transparency by explaining why it’s rational to answer the question whether one believes that p by answering the question whether p. Finally, in section four, I defend the simple theory against objections by arguing that self-knowledge constitutes an ideal of rationality. (shrink)

The main goal of this chapter is to argue that accessibilism in epistemology is incompatible with vehicle externalism in philosophy of mind. As we shall see, however, there are strong arguments for both of these positions. On the one hand, there is a compelling argument for vehicle externalism: the parity argument from Clark and Chalmers 1998. On the other hand, there is a compelling argument for accessibilism: the Moorean argument from Smithies 2012. If accessibilism is incompatible with vehicle externalism, (...) then both arguments cannot be sound. I resolve the tension by arguing that while the Moorean argument succeeds, the parity argument fails, and so vehicle externalism should be rejected on broadly epistemological grounds. (shrink)

This chapter is organized around four central questions about the role of reasons in the epistemology of perception. The 'whether?' question: does perception provide us with reasons for belief about the external world? The 'how?' question: how does perception provide us with reasons for belief about the external world? The 'when?' question: when does perception provide us with reasons for belief about the external world? The 'what?' question: what are the reasons that perception provides us with for belief about the (...) external world? (shrink)

This chapter has two goals: to motivate the foundationalist solution to the regress problem and to defend it against arguments from Sellars, BonJour and Klein. Both the motivation and the defence of foundationalism raise larger questions about the relationship between foundationalism and access internalism. I argue that foundationalism is not in conflict with access internalism, despite influential arguments to the contrary, and that access internalism in fact supplies a theoretical motivation for foundationalism. I conclude that foundationalism and access internalism form (...) a coherent and well-motivated package. (shrink)

A contribution to a book symposium on 'The Epistemic Role of Consciousness' by Declan Smithies (2019, OUP) in the Asian Journal of Philosophy. These comments focus on three themes from the book: (i) Zombies, (ii) the distinction between Propositional Justification and Doxastic Justification, (iii) Moorean Propositions.

Declan Smithies’ The Epistemic Role of Consciousness argues for “phenomenal mentalism,” according to which justification is determined synchronically and solely by phenomenally individuated mental states. Moreover, part I of the book argues for a few specific epistemic principles about perception, cognition, and introspection. My comments focus on the discussion of these specific principles and raise worries about the consistency with other ideas in the book, and about the arguments for these principles.

This is an excellent collection of essays on introspection and consciousness. There are fifteen essays in total (all new except for Sydney Shoemaker’s essay). There is also an introduction where the editors explain the impetus for the collection and provide a helpful overview. The essays contain a wealth of new and challenging material sure to excite specialists and shape future research. Below we extract a skeptical argument from Fred Dretske’s essay and relate the remaining essays to that argument. Due to (...) space limitations we focus in detail on just a few of the essays. We regret that we cannot give them all the attention they merit. (shrink)

This chapter defends the thesis that feeling conviction is sufficient for belief: if you feel conviction that p, then you believe that p. I begin with a neutral characterization of belief in terms of its normative profile: belief is a state that is subject to certain distinctive norms of rationality. The main argument of the chapter is that feelings of conviction are beliefs because they are subject to the same norms of rationality that govern our beliefs. Functionalists often deny that (...) feelings of conviction constitute beliefs when they play dysfunctional causal roles, as in cases of mad belief or delusion or implicit bias, but this only serves to obscure the kind of irrationality involved in such cases. These are dysfunctional beliefs, rather than non-doxastic states, or "in-between" cases. (shrink)

What is the role of affective experience in explaining how our desires provide us with reasons for action? When we desire that p, we are thereby disposed to feel attracted to the prospect that p, or to feel averse to the prospect that not-p. In this paper, we argue that affective experiences – including feelings of attraction and aversion – provide us with reasons for action in virtue of their phenomenal character. Moreover, we argue that desires provide us with reasons (...) for action only insofar as they are dispositions to have affective experiences. On this account, affective experience has a central role to play in explaining how desires provide reasons for action. (shrink)

This paper argues that justification is accessible in the sense that one has justification to believe a proposition if and only if one has higher-order justification to believe that one has justification to believe that proposition. I argue that the accessibility of justification is required for explaining what is wrong with believing Moorean conjunctions of the form, ‘p and I do not have justification to believe that p.’.

Does rationality require logical omniscience? Our best formal theories of rationality imply that it does, but our ordinary evaluations of rationality seem to suggest otherwise. This paper aims to resolve the tension by arguing that our ordinary evaluations of rationality are not only consistent with the thesis that rationality requires logical omniscience, but also provide a compelling rationale for accepting this thesis in the first place. This paper also defends an account of apriori justification for logical beliefs that is designed (...) to explain the rational requirement of logical omniscience. On this account, apriori justification for beliefs about logic has its source in logical facts, rather than psychological facts about experience, reasoning, or understanding. This account has important consequences for the epistemic role of experience in the logical domain. In a slogan, the epistemic role of experience in the apriori domain is not a justifying role, but rather an enabling and disabling role. (shrink)

What is the relationship between pleasure and desire? While some philosophers reduce pleasure to desire, this paper explores the prospects for a hedonic theory of desire, which reduces desire to pleasure instead. I argue that desiring that p is best analyzed not as a disposition to feel pleased that p when you believe that p, but rather as a disposition to feel pleasure in what you imagine when you imagine that p. I give three arguments for this hedonic theory of (...) desire, defend it against objections, and consider its broader theoretical implications for current debates in ethics and philosophy of mind.

This chapter provides a critical overview of several influential proposals about the epistemic function of higher-order evidence. I start by criticizing accounts of higher-order evidence that appeal to evidential defeat (§1), epistemic conflicts (§2), and unreasonable knowledge (§3). Next, I propose an alternative account that appeals to a combination of improper basing (§4) and non-ideal rationality (§5). Finally, I conclude by summarizing my reasons for preferring this account of higher-order evidence to the alternatives (§6).

Questions about the transparency of evidence are central to debates between factive and non-factive versions of mentalism about evidence. If all evidence is transparent, then factive mentalism is false, since no factive mental states are transparent. However, Timothy Williamson has argued that transparency is a myth and that no conditions are transparent except trivial ones. This paper responds by drawing a distinction between doxastic and epistemic notions of transparency. Williamson's argument may show that no conditions are doxastically transparent, but it (...) fails to show that no conditions are epistemically transparent. Moreover, this reinstates the argument from the transparency of evidence against factive mentalism. (shrink)

According to the Rationality Constraint, our concept of belief imposes limits on how much irrationality is compatible with having beliefs at all. We argue that empirical evidence of human irrationality from the psychology of reasoning and the psychopathology of delusion undermines only the most demanding versions of the Rationality Constraint, which require perfect rationality as a condition for having beliefs. The empirical evidence poses no threat to more relaxed versions of the Rationality Constraint, which only require only minimal rationality. Nevertheless, (...) we raise problems for all versions of the Rationality Constraint by appealing to more extreme forms of irrationality that are continuous with actual cases of human irrationality. In particular, we argue that there are conceivable cases of “mad belief” in which populations of Lewisian madmen have beliefs that are not even minimally rational. This undermines Lewis’s claim that our ordinary concept of belief is a theoretical concept that is implicitly defined by its role in folk psychology. We argue that introspection gives us a phenomenal concept of belief that cannot be analyzed by applying Lewis’s semantics for theoretical terms. (shrink)

What is involved in making an inference? This chapter argues against what Paul Boghossian calls the Taking Condition: "Inferring necessarily involves the thinker taking his premises to support his conclusion and drawing his conclusion because of that fact" (2014: 5). I won’t argue that the Taking Condition is incoherent: that nothing can coherently play the role that takings are supposed to play in inference. Instead, I’ll argue that it cannot plausibly explain all the inferential knowledge that we ordinarily take ourselves (...) to have. Moreover, I’ll argue that we don’t need it to understand the nature of inference. (shrink)

In his book, On Reflection, Hilary Kornblith criticizes what he regards as a chronic tendency in philosophy towards inflating the significance of reflection in ways that manifest a combination of philosophical naiveté and scientific ignorance about how reflection actually works. In these comments, I respond to Kornblith's challenge by sketching an account of the philosophical significance of reflection in the theory of epistemic justification.

In this paper, I argue that perception justifies belief about the external world in virtue of its phenomenal character together with its relations to the external world. But I argue that perceptual relations to the external world impact on the justifying role of perception only by virtue of their impact on its representational content. Epistemic level-bridging principles provide a principled rationale for avoiding more radically externalist theories of perceptual justification.

How is moral knowledge possible? This paper defends the anti-Humean thesis that we can acquire moral knowledge by deduction from wholly non-moral premises. According to Hume’s Law, as it has become known, we cannot deduce an ‘ought’ from an ‘is’, since it is “altogether inconceivable how this new relation can be a deduction from others, which are entirely different from it” (Hume, 1739, 3.1.1). This paper explores the prospects for a deductive theory of moral knowledge that rejects Hume’s Law.

This paper evaluates the claim that some desires provide reasons in virtue of their connection with conscious affective experiences like feelings of attraction or aversion. I clarify the nature of affective desires and several distinct ways in which affective desires might provide reasons. Against accounts proposed by Ruth Chang, Declan Smithies and Jeremy Weiss, I motivate doubts that it is the phenomenology of affective experiences that explains their normative or rational significance. I outline an alternative approach that centralises (...) the function of such experiences. (shrink)

Some philosophers claim that perception immediately and prima facie justifies belief in virtue of its phenomenal character (Huemer, Skepticism and the veil of perception. Rowman & Littlefield, Lanham, 2001; Pryor, There is immediate justification. In: Steup M, Sosa E (eds) Contemporary debates in epistemology. Blackwell, London (2014), pp. 181–202, 2005). To explain this special justificatory power, some appeal to perception’s presentational character: the idea that perceptual experience presents its objects as existing here-and-now (Chudnoff, Intuition. Oxford University Press, Oxford, 2013; Berghofer, (...) Husserl Stud 34(2):145–170, 2018). As some philosophers have noted, if perception justifies in virtue of its presentational character alone, the kind of content perception has should not matter for perceptual justification; more precisely, it should not matter whether perceptual content is propositional or not (e.g., Smithies, The epistemic role of consciousness. Oxford University Press, Oxford, 2019; Kriegel, Australas J Philos, 2021). However, most philosophers tend to resist this conclusion, holding that perception must be propositional in order to justify, on the ground that all our model of justification are propositional (e.g., Gauker, Philos Perspect 26(1):19–50, 2012). This paper challenges this claim. The paper consists of a negative and a positive part. In the negative part, I discuss and reject the master argument for the propositionality of perception; the conclusion is that propositional content is neither sufficient nor necessary to explain perception’s justificatory power. In the positive part, I take this conclusion seriously and outline an objectual model of perceptual justification. I define objectual attitudes as mental states whose content is not a full proposition, but a sub-propositional representational item, such as the representation of objects, properties, and kinds (Grzankowski and Montague, Non-propositional intentionality. Oxford University Press, Oxford, 2018), and show that it is plausible that some perceptions and some beliefs are attitudes of this kind. I then argue that objectual perceptual experiences have the right kind of phenomenal character and the right kind of structure to serve for immediate prima facie justification. I conclude by defending my objectual model from three objections. (shrink)

A comprehensive view of human transformation can only come through an absolute understanding of human nature and process of evolution. The dimension of the human personality provides the point for initiation to assess and understand their process of development. This further leads to an inquiry into what comes next and where would this development lead to? Is the development an end or a means to achieve a higher goal of attaining transcendence? The focus of every human life is to reach (...) the pinnacle of human existence and, the doorway of same leads through the way of consciousness and spiritual evolution. It is possible that the two terminologies, evolution and development are interconnected and in a way influence each other. Spiritual evolution is the result of a conscious effort to develop one self, in other words evolution is the outcome of development. The state of mind where a human being achieves the spiritual evolution requires the needs of the mind to be fulfilled, so it is through knowledge that a being experiences integral consciousness and achieves the state of transcendence.

The theory of mind that medieval philosophers inherit from Augustine is predicated on the thesis that the human mind is essentially self-reflexive. This paper examines Peter John Olivi's (1248-1298) distinctive development of this traditional Augustinian thesis. The aim of the paper is three-fold. The first is to establish that Olivi's theory of reflexive awareness amounts to a theory of phenomenal consciousness. The second is to show that, despite appearances, Olivi rejects a higher-order analysis of consciousness in favor of a same-order (...) theory. The third and final is to show that, on his view, consciousness is both self-intimating and infallible. (shrink)

Evolutionary epistemology (Lorenz, Vollmer) and value-driven decision theory (Pugh) are used to explain the fundamental properties of consciousness. It is shown that this approach is compatible with global workspace theory (Baars) and global neuronal workspace theory (De Haene). The emotions are, however, that what drives consciousness. A hypothetical evolutionary tree of the emotions is given – intended to show that consciousness evolves and is probably qualitatively different in different groups of animals.

As I assume to begin with, animals with a high level of consciousness, are those beings which are more dependent on their materialistic ecological circumstances than those with less cognition. The most obvious support for this factual claim is the yet still unofficial unit of geological time named the Anthropocene Epoch demarcating human devastation of earthly resources, whereby there is no doubt which species on earth is the most materially dependent. Notwithstanding, we need to keep things quantitively in perspective. Of (...) the 545.8 gigatons of biomass on Earth of which most is plants, animals make up 0.47% while humans only 0.01%, bacteria reigns supreme with 12.8% of total. (shrink)

Applying Bernard Lonergan's (1957/1992, 1972) analysis of intentional consciousness and its concomitant epistemology, this paper highlights epistemological confusion in contemporary consciousness studies as exemplified mostly in David Chalmers's (1996) position. In ideal types, a first section outlines two epistemologies-sensate-modeled and intelligence-based-whose difference significantly explains the different positions. In subsequent sections, this paper documents the sensate-modeled epistemology in Chalmers's position and consciousness studies in general. Tellingly, this model of knowing is at odds with the formal-operational theorizing in twentieth-century science. This paper (...) then links this epistemology with functionalism and its focus on descriptive efficient causality in external behaviors and its oversight of explanatory formal causality; highlights the theoretical incoherence of the understanding of science in the functionalist approach; connects it with the construal of consciousness as primarily intentional (i.e., directed toward an object) to the neglect of consciousness as conscious (i.e., constituted by a non-objectified self-presence); and relates this outcome to the reduction of human consciousness to animal-like perception and mechanistic interactions. A brief conclusion summarizes these multiple, subtle, and interconnected considerations and suggests how only an intellectual epistemology would be adequate to the intellectual nature of human consciousness and the world of meaning, not of mere bodies, in which humans exist.

Frustration has been growing with mainstay epistemological methods of logical deduction and experimental falsification for assessing theories of consciousness. This paper explores one among several alternatives being proposed: the listed requirements epistemology. A literature search identifies five papers that explicitly list requirements for assessing consciousness theories. These five lists are analysed as a promising starting point, but as yet insufficiently comprehensive to do the method justice. The longest list has 11 items, but 19 unique items are identified across the five (...) lists and a taxonomic analysis by category further surfaces at least 30 potential candidates. Four limitations of the method are discussed, arguing that it is best treated as one practical tool as part of a broader strategy for rigorously assessing consciousness theories and identifying avenues for future research. The conclusion describes a workplan for a sufficiently complete working taxonomy to support the field’s collective endeavours. (shrink)

The goal of this programmatic paper is to highlight a close connection between the core problem in the philosophy of medicine, i.e. the concept of health, and the core problem of the philosophy of mind, i.e. the concept of consciousness. I show when we look at these phenomena together, taking the evolutionary perspective of modern state-based behavioural and life-history theory used as the teleonomic tool to Darwinize the agent- and subject-side of organisms, we will be in a better position to (...) make sense of them both as natural phenomena.

In this paper, we take a meta-theoretical stance and aim to compare and assess two conceptual frameworks that endeavor to explain phenomenal experience. In particular, we compare Feinberg & Mallatt’s Neurobiological Naturalism (NN) and Tononi’s and colleagues' Integrated Information Theory (IIT), given that the former pointed out some similarities between the two theories (Feinberg & Mallatt 2016c-d). To probe their similarity, we first give a general introduction to both frameworks. Next, we expound a ground plan for carrying out our analysis. (...) We move on to articulate a philosophical profile of NN and IIT, addressing their ontological commitments and epistemological foundations. Finally, we compare the two point-by-point, also discussing how they stand on the issue of artificial consciousness. (shrink)

There is good reason to think that, in every case of perceptual consciousness, there is something of which we are conscious; but there is also good reason to think that, in some cases of perceptual consciousness—for instance, hallucinations—there is nothing of which we are conscious. This paper resolves this inconsistency—which we call the presentation problem—by (a) arguing that ‘conscious of’ and related expressions function as intensional transitive verbs and (b) defending a particular semantic approach to such verbs, on which they (...) have readings that lack direct objects or themes. The paper further argues that this approach serves not only as a linguistic proposal about the semantics of ‘conscious of’, but also as a proposal about the metaphysics of conscious states. (shrink)

Recent work within such disparate research areas as the epistemology of perception, theories of well-being, animal and medical ethics, the philosophy of consciousness, and theories of understanding in philosophy of science and epistemology has featured disconnected discussions of what is arguably a single underlying question: What is the value of consciousness? The purpose of this paper is to review some of this work and place it within a unified theoretical framework that makes contributions (and contributors) from these disparate areas more (...) visible to one another.

Sometimes we learn through the use of imagination. The epistemology of imagination asks how this is possible. One barrier to progress on this question has been a lack of agreement on how to characterize imagination; for example, is imagination a mental state, ability, character trait, or cognitive process? This paper argues that we should characterize imagination as a cognitive ability, exercises of which are cognitive processes. Following dual process theories of cognition developed in cognitive science, the set of imaginative processes (...) is then divided into two kinds: one that is unconscious, uncontrolled, and effortless, and another that is conscious, controlled, and effortful. This paper outlines the different epistemological strengths and weaknesses of the two kinds of imaginative process, and argues that a dual process model of imagination helpfully resolves or clarifies issues in the epistemology of imagination and the closely related epistemology of thought experiments.

I show that some of the most initially attractive routes of refuting epistemological solipsism face serious obstacles. I also argue that for creatures like ourselves, solipsism is a genuine form of external world skepticism. I suggest that together these claims suggest the following morals: No proposed solution to external world skepticism can succeed which does not also solve the problem of epistemological solipsism. And, more tentatively: In assessing proposed solutions to external world skepticism, epistemologists should explicitly consider whether those solutions (...) extend to knowledge of other minds. Finally, and also tentatively: epistemological solipsism warrants more philosophical attention than it currently enjoys. (shrink)
