I elaborate and defend a set of metaphysical and epistemic claims that comprise what I call the acquaintance approach to introspective knowledge of the phenomenal qualities of experience. The hallmark of this approach is the thesis that, in some introspective judgments about experience, (phenomenal) reality intersects with the epistemic, that is, with the subject’s grasp of that reality. In Section 1 of the paper I outline the acquaintance approach by drawing on its Russellian lineage. A more detailed picture of the (...) approach emerges in succeeding sections, which respond to a range of objections. Some critics charge that approaches of this sort are overly idealized, in that they ignore the cognitive flaws and limitations of actual human beings. I begin to address these worries in Section 2, by arguing that the epistemic commitments of the acquaintance approach are in fact relatively modest. In Section 3, I sketch a picture of introspective reference that explains how phenomenal reality can intersect with the epistemic in a phenomenal judgment, as the acquaintance approach requires. Drawing on this picture of introspective reference, Section 4 sets out a practical strategy for achieving knowledge by acquaintance. Some contemporary acquaintance theorists (BonJour 2003, Fumerton 1996) employ demanding epistemic standards for knowledge by acquaintance, standards beyond those mandated by the acquaintance approach. In Section 5 I show that instances of introspective knowledge that meet less demanding standards can satisfy the acquaintance approach’s epistemic commitments. The final sections concern the most direct challenges to the acquaintance approach, which target the claim that phenomenal reality intersects with the epistemic. According to one such challenge, this claim is belied by the fact that possessing a phenomenal concept is a matter of having certain dispositions. Section 6 draws on a discussion by Sosa (2003) to articulate this challenge, and responds to it on behalf of the acquaintance approach. Section 7 addresses Stalnaker’s (2008) worry that, if phenomenal reality intersected with the epistemic, phenomenal information would be incommunicable. (shrink)

Sydney Shoemaker, developing an idea of Wittgenstein’s, argues that we are immune to error through misidentification relative to the first-person pronoun. Although we might be liable to error when “I” (or its cognates) is used as an object, we are immune to error when “I” is used as a subject (as when one says, “I have a toothache”). Shoemaker claims that the relationship between “I” as-subject and the mental states of which it is introspectively aware is tautological: when, say, we (...) judge that “I feel pain,” we are tautologically aware that feels pain is instantiated and that it is instantiated in oneself. Moreover, he contends that this relationship holds not just for bodily sensations, but also for the sense of agency and for visual perception. But we deny that this relationship is tautological; instead, we treat Shoemaker’s principle (IEM) as a hypothesis. We then proceed to show that certain pathological states and experimentally-induced illusions can be adduced to show that IEM describes not a necessary relationship but a contingent relationship, one that sometimes fails to obtain. That we are not immune to error in the way Shoemaker describes has grave consequences for many aspects of his ideas concerning the first-person perspective. In the course of arguing that these empirical phenomena count against IEM, we also show that not only can the content of conscious experience be misrepresented, so too can the subject: that is, not only can the what of conscious experience be misrepresented, so too can the who.

In lieu of an abstract, here is a brief excerpt of the content:Philosophy, Psychiatry, & Psychology 9.1 (2002) 35-39 [Access article in PDF] The Ownership of Thoughts John Campbell Keywords: schizophrenia, thought insertion, immunity to error through misidentification. SYDNEY SHOEMAKER FORMULATED a basic point about first-person, present-tense ascriptions of psychological states when he declared that they are, in general, immune to error through misidentification (Shoemaker 1984). Assuming Shoemaker's point to be correct, the puzzle it raises is this: how are we (...) to explain this datum? Why should it be that first-person, present-tense ascriptions of psychological states are immune to error through misidentification? One type of explanation is in terms of the meaning of the first person: that "I" just stands for whoever is the owner of these (demonstrated) psychological states (including any states being self-ascribed). I argued against this account of the first person in a number of places, and in favor of an alternative explanation of Shoemaker's datum. On the alternative explanation, the reason for the immunity is provided by an account of the ownership of psychological states, on which what makes a psychological state mine is the possibility of self-ascription of it by me (Campbell 1986, 1999a). Suppose we call this the Introspectionist explanation of the immunity to error through misidentification of present-tense self-ascriptions of psychological states. I do think, though, that the simple Introspectionist account is too simple an account of Shoemaker's datum (Campbell 1999a, 1999b). The reason is that there is a certain complexity in our notion of the ownership of a token thought. We cannot give a full account of our ordinary notion of the ownership of a thought simply in terms of the person who is capable of introspective knowledge of the thought. The reason is that there is another dimension to our ordinary notion of the ownership of a thought. We also think of the possessor of a thought as being the person who generated that very thought; we think of the owner of the thought as being the person who brought that particular token thought into existence, the person who formed it. Of course, that token thought may be a copying of someone else's idea; that other person may have influenced my formation of that particular thought. But the point remains that I play a special role in the production of my thoughts.Suppose we have a document bearing a signature and we ask, "Whose signature is that?" In this case we are asking about the authorship of the signature; we are asking who made those particular marks on that bit of paper. Of course, someone else can copy my signature, trying to make it look as if what they write was written by me. But for a particular piece of writing to be an authentic signature of mine, the thing has to be generated by me personally. I think it is helpful to bear in mind this aspect of the notion of the ownership of a signature, when we consider a certain complexity in the notion of the ownership of a thought—I mean, an occurrent, episodic [End Page 35] thought. There are, I am saying, two strands in the ordinary notion of the ownership of a thought, which we do not ordinarily have any reason to separate. First, there is the notion of the person who generated that particular thought, which we might think of on the model of the person who inscribed a particular signature. Of course, in generating a particular token thought, you may be subject to all sorts of influences. Perhaps your thought is derivative, largely shaped by others. Perhaps your thoughts are sometimes simply echoes of the things other people have said. Nonetheless, when we consider how your individual token thoughts are being brought about, you play a proximal role in their formation that no one else does. To give an analogy, suppose that I am taking notes at your dictation. Then there is a sense in which the contents of my notes are entirely determined by you. But there is also a sense in which the token sentences are being generated by... (shrink)

This paper deals with the semantics of de dicto , de re and de se belief reports. First, I flesh out in some detail the established, classical theories that assume syntactic distinctions between all three types of reports. I then propose a new, unified analysis, based on two ideas discarded by the classical theory. These are: (i) modeling the de re/de dicto distinction as a difference in scope, and (ii) analyzing de se as merely a special case of relational de (...) re attitudes. The resurrection of these ideas takes place in a dynamic setting. My formalization of the first idea involves a modification of the presupposition-as-anaphora resolution algorithm for DRT. The second involves treating acquaintance relations as second-order presuppositions, to be bound in the context by means of higher-order unification, or accommodated if necessary. The resulting framework requires no syntactic distinctions between different modes of attitude, with the exception of a specific subclass of de se reports characterized by special ‘ de se pronouns’ (i.e. PRO and logophors). These special pronouns are handled in syntax; everything alse is passed on to the pragmatic resolution module as it appears on the surface. The more sophisticated contextual resolution process nonetheless ensures adequate output truth conditions for a variety of classical and novel puzzles. In particular, I compare the new pragmasemantic system to the classical, syntactic analysis with respect to iterated and quantified reports, and monstrously shifted indexicals. (shrink)

I offer an account of thought insertion based on a certain model of self-knowledge. I propose that subjects with thought insertion do not experience being committed to some of their own beliefs. A hypothesis about self-knowledge explains why. According to it, we form beliefs about our own beliefs on the basis of our evidence for them. First, I will argue that this hypothesis explains the fact that we feel committed to those beliefs which we are aware of. Then, I will (...) point to one feature of schizophrenia that suggests that subjects with thought insertion may not be able to know their own beliefs in that way. (shrink)

The paper develops a conception of epistemic warrant as applied to perceptual belief, called "entitlement", that does not require the warranted individual to be capable of understanding the warrant. The conception is situated within an account of animal perception and unsophisticated perceptual belief. It characterizes entitlement as fulfillment of an epistemic norm that is apriori associated with a certain representational function that can be known apriori to be a function of perception. The paper connects anti-individualism, a thesis about the nature (...) of mental states, and perceptual entitlement. It presents an argument that explains the objectivity and validity of perceptual entitlement partly in terms of the nature of perceptual states–hence the nature of perceptual beliefs, which are constitutively associated with perceptual states. The paper discusses ways that an individual can be entitled to perceptual belief through its connection to perception, and ways that entitlement to perceptual belief can be undermined. (shrink)

Our thought and talk are situated. They do not take place in a vacuum but always in a context, and they always concern an external situation relative to which they are to be evaluated. Since that is so, François Recanati argues, our linguistic and mental representations alike must be assigned two layers of content: the explicit content, or lekton, is relative and perspectival, while the complete content, which is absolute, involves contextual factors in addition to what is explicitly represented. Far (...) from reducing to the context-independent meaning of the sentence-type or, in the psychological realm, to the 'narrow' content of mental representations, the lekton is a level intermediate between context-invariant meaning and full propositional content. Recognition of that intermediate level is the key to a proper understanding of context-dependence in language and thought. Going beyond the usual discussions of indexicality and unarticulated constituents in the philosophy of language, Recanati turns to the philosophy of mind for decisive arguments in favour of his approach. He shows, first, that the lekton is the notion of content we need if we are to properly understand the relations between perception, memory, and the imagination, and second, that the psychological 'mode' is what determines the situation the lekton is relative to. In this framework he provides a detailed account of de se thought and the first person point of view. In the last part of the book, Recanati discusses the special freedom we have, in discourse and thought, to shift the situation of evaluation. He traces that freedom to a special mode - the anaphoric mode - which enables us to go beyond the egocentric stage of pre-human thought. (shrink)

Being Known is a response to a philosophical challenge which arises for every area of thought: to reconcile a plausible account of what is involved in the truth of statements in a given area with a credible account of how we can know those statements. Christopher Peacocke presents a framework for addressing the challenge, a framework which links both the theory of knowledge and the theory of truth with the theory of concept-possession.

Since Sydney Shoemaker published his seminal article ‘Self-Reference and Self-Awareness’ in 1968, the notion of ‘Immunity to Error through Misidentification’ has received much attention. It crops up in discussions of personal identity, indexical thought and introspection, and has been used to interpret remarks made by philosophers from Wittgenstein to William James. The precise significance of IEM is often unspecified in these discussions, however. It is unclear, for example, whether it constitutes an important status of judgments, whether it explains an important (...) characteristic of judgments, or whether it merely marks an important characteristic of judgments. Nevertheless, reference to IEM abounds, making this obscure notion seem all the more significant. (shrink)

Two kinds of epistemological sceptical paradox are reviewed and a shared assumption, that warrant to accept a proposition has to be the same thing as having evidence for its truth, is noted. 'Entitlement', as used here, denotes a kind of rational warrant that counterexemplifies that identification. The paper pursues the thought that there are various kinds of entitlement and explores the possibility that the sceptical paradoxes might receive a uniform solution if entitlement can be made to reach sufficiently far. Three (...) kinds of entitlement are characterized and given prima facie support, and a fourth is canvassed. Certain foreseeable limitations of the suggested antisceptical strategy are noted. The discussion is grounded, overall, in a conception of the sceptical paradoxes not as directly challenging our having any warrant for large classes of our beliefs but as crises of intellectual conscience for one who wants to claim that we do.

Something about this argument sounds funny. As we’ll see, though, it takes some care to identify exactly what Moore has done wrong. Iwill assume that Moore knows premise (2) to be true. One could inquire into how he knows it, and whether that knowledge can be defeated; but Iwon’t. I’ll focus instead on what epistemic relations Moore has to premise (1) and to his conclusion (3). It may matter which epistemic relations we choose to consider. Some philosophers will diagnose Moore’s (...) argument using Contextualist machinery. They’ll say. (shrink)

The paper defends a version of Direct Reference for indexicals on which reference-fixing material (token-reflexive conditions) plays the role of an ancillary presupposition.

Definite descriptions, I shall argue, have two possible functions. 1] They are used to refer to what a speaker wishes to talk about, but they are also used quite differently. Moreover, a definite description occurring in one and the same sentence may, on different occasions of its use, function in either way. The failure to deal with this duality of function obscures the genuine referring use of definite descriptions. The best known theories of definite descriptions, those of Russell and Strawson, (...) I shall suggest, are both guilty of this. Before discussing this distinction in use, I will mention some features of these theories to which it is especially relevant. (shrink)

A self-ascription is a thought or sentence in which a predicate is self-consciously ascribed to oneself. Self-ascriptions are best expressed using the first-person pronoun. Mental self-ascriptions are ascriptions to oneself of mental predicates (predicates that designate mental properties), non-mental self-ascriptions are ascriptions to oneself of non-mental predicates (predicates that designate non-mental properties). It is often claimed that there is a range of self-ascriptions that are immune to error through misidentification relative to the first-person pronoun (IEM for short). What this means, (...) and exactly which self-ascriptions are properly classed as IEM, is a topic hotly disputed. Some claim that only mental self-ascriptions are IEM, others claim that some non-mental self-ascriptions are IEM. Before this question can be decided, it needs to be judged exactly what it means to say that a self-ascription is IEM. And here we stumble across the fact that there are, at least, two non-equivalent ways of defining the phenomenon1. I will be claiming that one of these definitions should be rejected. (shrink)

Self-Knowledge and Self-Reference is a defense and reconciliation of the two apparently conflicting theses that the self is peculiarly elusive and that our basic, cogito-judgments are certain. On the one hand, Descartes seems to be correct that nothing is more certain than basic statements of self-knowledge, such as "I am thinking." On the other hand, there is the compelling Humean observation that when we introspect, nothing is found except for various "impressions." The problem, then, is that the Humean and Cartesian (...) insights are both initially appealing, yet they appear to be in tension with one another. In this paper I attempt to satisfy both intuitions by developing a roughly descriptivist account of self-reference according to which our certainty in basic beliefs stems precisely from our needing to know so little in order to have them.

John Campbell (1999) has recently maintained that the phenomenon of thought insertion as it is manifested in schizophrenic patients should be described as a case in which the subject is introspectively aware of a certain thought and yet she is wrong in identifying whose thought it is. Hence, according to Campbell, the phenomenon of thought insertion might be taken as a counterexample to the view that introspection-based mental selfascriptions are logically immune to error through misidentification (IEM, hereafter). Thus, if Campbell (...) is right, it would not be true that when the subject makes a mental self-ascription on the basis of introspective awareness of a given mental state, there is no possible world in which she could be wrong as to whether it is really she who has that mental state. Notice the interesting interdisciplinary implications of Campbell’s project: on the one hand, a fairly precise notion elaborated in philosophy such as IEM (and the related notion of error through misidentification, EM hereafter) is used to describe a characteristic symptom of schizophrenia.1 On the other hand, such a phenomenon, described in the way proposed, is taken to be a possible counterexample to a sort of “philosophical dogma” such as IEM of introspection-based non-inferential mental self-ascriptions. In the first section of the paper I will point out the characteristic features of EM and explain logical immunity to error through misidentification of introspection-based mental self-ascriptions; in the second section I will consider the case of thought insertion in more detail and show why, after all, it is not a counterexample to the view that introspectionbased mental self-ascriptions are logically IEM. Finally, I will offer a re-description of the phenomenon of thought insertion. (shrink)

In this paper, I present a version of a sense-data approach to perception, which differs to a certain extent from well-known versions like the one put forward by Jackson. I compare the sense-data view to the currently most popular alternative theories of perception, the so-called Theory of Appearing (a very specific form of disjunctivist approaches) on the one hand and reductive representationalist approaches on the other. I defend the sense-data approach on the basis that it improves substantially on those alternative (...) theories. (shrink)

Perry argues that certain sorts of indexicals are 'essential', in the sense that they cannot be eliminated in favor of descriptions. This paper also introduces the influential idea that certain sorts of indexicals play a special role in thought, and have a special connection to action.

A transcript of three lectures, given at Princeton University in 1970, which deals with (inter alia) debates concerning proper names in the philosophy of language.

It is only in fairly recent philosophy that psychological self-knowledge has come to be seen as problematical; once upon a time the hardest philosophical difficulties all seemed to attend our knowledge of others. But as philosophers have canvassed various models of the mental that would make knowledge of other minds less intractable, so it has become unobvious how to accommodate what once seemed evident and straightforward–the wide and seemingly immediate cognitive dominion of minds over themselves.

According to Donnellan the characteristic mark of a referential use of a definite description is the fact that it can be used to pick out an individual that does not satisfy the attributes in the description. Friends and foes of the referential/attributive distinction have equally dismissed that point as obviously wrong or as a sign that Donnellan's distinction lacks semantic import. I will argue that, on a strict semantic conception of what it is for an expression to be a genuine (...) referential device, Donnellan is right: if a use of a definite description is referential, it must be possible for it to refer to an object independently of any attributes associated with the description, including those that constitute its conventional meaning.

Robert Stalnaker explores the contexts in which speech takes place, the ways we represent them, and the roles they play in explaining the interpretation and dynamics of speech. His central thesis is the autonomy of pragmatics: the independence of theory about structure and function of discourse from theory about mechanisms serving those functions.

In this paper I elaborate on previous criticisms of the influential Stalnakerian account of presuppositions, pointing out that the well-known practice of informative presupposition puts heavy strain on Stalnaker’s pragmatic characterization of the phenomenon of presupposition, in particular of the triggering of presuppositions. Stalnaker has replied to previous criticisms by relying on the well-taken point that we should take into account the time at which presupposition-requirements are to be computed. In defense of a different, ‘semantic’ account of the phenomenon of (...) presupposition, I argue that that point does not suffice to rescue the Stalnakerian proposal, and I portray Lewisian ‘accommodation’ as one way in which speakers adjust themselves to one another in the course of conversation.

The communication of de se attitudes poses a problem for “participant- neutral” analyses of communication in terms of propositions expressed or proposed updates to the common ground: when you tell me “I am an idiot”, you express a first person de se attitude, but as a result I form a different, second person attitude, viz. that you are an idiot. I argue that when we take seriously the asymmetry between speaker and hearer in semantics this problem disappears. To prove this (...) I propose a concrete model of communication as the transmission of information from the speaker’s mental state to the hearer’s. My analysis is couched in Discourse Representation Theory, a formal semantic framework that linguists use for modeling conversational common ground updates, but that can also be applied to describe the individual speech participants’ dynamically changing mental states.

Cappelen and Dever present a forceful challenge to the standard view that perspective, and in particular the perspective of the first person, is a philosophically deep aspect of the world. Their goal is not to show that we need to explain indexical and other perspectival phenomena in different ways, but to show that the entire topic is an illusion.

What is the metaphysical nature of perceptual experience? What evidence does experience provide us with? These questions are typically addressed in isolation. In order to make progress in answering both questions, perceptual experience needs to be studied in an integrated manner. I develop a unified account of the phenomenological and epistemological role of perceptual experience, by arguing that sensory states provide perceptual evidence due to their metaphysical structure. More specifically, I argue that sensory states are individuated by the perceptual capacities (...) employed and that there is an asymmetric dependence between their employment in perception and their employment in hallucination and illusion. Due to this asymmetric dependence, sensory states provide us with evidence. (shrink)

Inspired by Rudolf Carnap's Der Logische Aufbau Der Welt, David J. Chalmers argues that the world can be constructed from a few basic elements. He develops a scrutability thesis saying that all truths about the world can be derived from basic truths and ideal reasoning. This thesis leads to many philosophical consequences: a broadly Fregean approach to meaning, an internalist approach to the contents of thought, and a reply to W. V. Quine's arguments against the analytic and the a priori. (...) Chalmers also uses scrutability to analyze the unity of science, to defend a conceptual approach to metaphysics, and to mount a structuralist response to skepticism. Based on the 2010 John Locke lectures, Constructing the World opens up debate on central philosophical issues involving language, consciousness, knowledge, and reality. This major work by a leading philosopher will appeal to philosophers in all areas. This entry contains uncorrected proofs of front matter, chapter 1, and first excursus. (shrink)

Self-knowledge is the focus of considerable attention from philosophers: Knowing Our Own Minds gives a much-needed overview of current work on the subject, bringing together new essays by leading figures. Knowledge of one's own sensations, desires, intentions, thoughts, beliefs, and other attitudes is characteristically different from other kinds of knowledge: it has greater immediacy, authority, and salience. The contributors examine philosophical questions raised by the distinctive character of self-knowledge, relating it to knowledge of other minds, to rationality and agency, externalist (...) theories of psychological content, and knowledge of language. Together these original, stimulating, and closely interlinked essays demonstrate the special relevance of self-knowledge to a broad range of issues in epistemology, philosophy of mind, and philosophy of language.

The truth of a statement depends on the world in two ways: what the statement says is true if the world is as the statement says it is; on the other hand, what the expressions in the statement mean depends on what the world is like (for instance, on what conventions are in place). Each of these two kinds of dependence of truth on the world corresponds to one of the dimensions on the two-dimensional semantic framework, developed in the 1970’ (...) in the work of Evans, Kaplan, Kripke and Stalnaker. The introduction provides a systematic overview of the framework, the ideas of its earlier originators, recent developments and criticism. Finally, it gives a brief overview over the contributions to the volume. (shrink)
