In this collection of newly commissioned essays, the contributors present a variety of approaches to it, engaging with historical and empirical aspects of the subject as well as contemporary philosophical work.

I argue that immunity to error through misidentification primarily characterizes thoughts that are 'implicitly' de se, as opposed to thoughts that involve an explicit self-identification. Thoughts that are implicitly de se involve no reference to the self at the level of content: what makes them de se is simply the fact that the content of the thought is evaluated with respect to the thinking subject. Or, to put it in familiar terms : the content of the (...) thought is a property which the thinking subject self-ascribes (as in the Loar/Lewis/Chisholm analysis). After answering an objection (to the effect that immunity can affect explicit de se thoughts), I extend the analysis to demonstrative thoughts, which also exhibit the property of immunity to error through misidentification.

In this paper we introduce a paradigm of experiment which, we believe, is of interest both in psychology and philosophy. There the subject wears an HMD (head-mount display), and a camera is set up at the upper corner of the room, in which the subject is. As a result, the subject observes his own body through the HMD. We will mainly focus on the philosophical relevance of this experiment, especially to the thesis of so-called 'immunity to error (...) through misidentification relative to the first-person pronoun'. We will argue that one experiment conducted in this setting, which we call the bodily illusion experiment, provides a counterexample to that thesis. (shrink)

Autobiographical memories typically give rise either to memory reports (“I remember going swimming”) or to first person past-tense judgements (“I went swimming”). This article focuses on first person past-tense judgements that are (epistemically) based on autobiographical memories. Some of these judgements have the IEM property of being immune to error through misidentification. This article offers an account of when and why first person past-tense judgements have the IEM property.

Saying ┌ that ψ is F ┐ when one should have said ┌ that φ is F ┐ involves making one of two different kinds of error. Either the wrong nominal term (┌ ψ ┐ instead of ┌ φ ┐) is ascribed to the right object or the right nominal term is ascribed to the wrong object. Judgments susceptible to one kind of error are immune to the other. Indexical terms such as ‘here’ and ‘now’ exhibit a corresponding (...) pattern of immunity and susceptibility to error, which suggests that they are complex demonstratives. This should also apply to ‘I’. (shrink)

I discuss an aspect of the relation between accounts of de se thought and the phenomenon of immunity to error through misidentification. I will argue that a deflationary account of the latter—the Simple Account, due to Evans —will not do; a more robust one based on an account of de se thoughts is required. I will then sketch such an alternative account, based on a more general view on singular thoughts, and show how it can deal (...) with the problems I raise for the Simple Account. (shrink)

Are those judgments that we make on the basis of our memories immune to error through misidentification? In this paper, I discuss a phenomenon which seems to suggest that they are not; the phenomenon of observer memory. I argue that observer memories fail to show that memory judgments are not IEM. However, the discussion of observer memories will reveal an interesting fact about the perspectivity of memory; a fact that puts us on the right path towards explaining (...) why memory judgments are indeed IEM. The main tenet in the account of IEM to be proposed is that this aspect of memory is grounded, on the one hand, on the intentionality of perception and, on the other hand, on the relation between the intentionality of perception and that of memory. (shrink)

It has been observed that, unlike other kinds of singular judgments, mental self-ascriptions are immune to error through misidentification: they may go wrong, but not as a result of mistaking someone else’s mental states for one’s own. Although recent years have witnessed increasing interest in this phenomenon, three basic questions about it remain without a satisfactory answer: what is exactly an error through misidentification? What does immunity to such errors consist in? And what (...) does it take to explain the fact that mental self-ascriptions exhibit this sort of immunity? The aim of this paper is to bring these questions into focus, propose some tentative answers and use them to show that one prominent attempt to explain the immunity to error through misidentification of mental self-ascriptions is unsuccessful. (shrink)

In The Blue Book, Wittgenstein defined a category of uses of “I” which he termed “I”-as-subject, contrasting them with “I”-as-object uses. The hallmark of this category is immunity to error through misidentification (IEM). This article extends Wittgenstein’s characterisation to the case of memory-judgments, discusses the significance of IEM for self-consciousness—developing the idea that having a first-person thought involves thinking about oneself in a distinctive way in which one cannot think of anyone or anything else—and refutes a (...) common objection to the claim that memory-judgments exhibit IEM. (shrink)

The claim that episodic memory is immune to error through misidentification enjoys continuing popularity in philosophy. Psychological research on observer memory—usually defined as occurring when one remembers an event from a point of view other than that that from which he originally experienced it—would seem, on the face of it, to undermine the IEM claim. Relying on a certain view of memory content, Fernández, however, has provided an ingenious argument for the view that it does not. This (...) paper reconstructs Fernández’ argument and shows that there is reason to reject the definition of observer memory and the view of memory content on which it relies. Once these are rejected, it turns out that observer memory does indeed imply that the IEM claim is false. (shrink)

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)

The aim of this paper is to defend the view that judgments based on episodic memory are immune to error through misidentification. I will put forward a proposal about the contents of episodic memories according to which a memory represents a perception of a past event. I will also offer a proposal about the contents of perceptual experiences according to which a perceptual experience represents some relations that its subject bears to events in the external world. The (...) combination of the two views will yield the outcome that the subject is always an intentional object of her own memories: In episodic memory, one remembers being the subject whose extrinsic properties were experienced in some past perception. For that reason, one cannot misidentify oneself in memory unless one is having an inaccurate memory. Thus, the source of immunity to error through misidentification in memory lies in the nature of mnemonic content. (shrink)

Fernández offers an account of the nature of episodic memory that marries two core ideas: role-functionalism about episodic memory, and self-reflexive mnemonic content. One payoff of this view is that episodic memory judgments are immune to error through misidentification. Fernández takes this to reveal something important about the nature of one’s self-awareness in memory and our first-person conception of ourselves. However, once one sees why such judgments are immune in this way, according to the proposed account, the (...) fact that they are immune becomes moot. While technically immune to error through misidentification, episodic memory judgments are not grounded in a way such that they have any interesting epistemological import for the subject, and any insights about our self-awareness and self-conception are directly derivable from the metaphysics of memory content alone. (shrink)

Recanati’s (2007, 2009) argues for a Lewisian subjectless view of the content of “implicit” de se thought, on the basis that we can thus better explain the phenomenon of immunity to error through misidentification. The paper argues that this is not the case, and suggests that such a view is in tension with Recanati’s mental files approach to de re thought in general and the SELF concept in particular.

Abstract: Some first person statements, such as ‘I am in pain’, are thought to be immune to error through misidentification (IEM): I cannot be wrong that I am in pain because—while I know that someone is in pain—I have mistaken that person for myself. While IEM is typically associated with the self-ascription of psychological properties, some philosophers attempt to draw anti-Cartesian conclusions from the claim that certain physical self-ascriptions are also IEM. In this paper, I will examine (...) whether some physical self-ascriptions are in fact IEM, and—if they are—what role that fact is supposed to play in arguments for the anti-Cartesian claim that self-consciousness is consciousness of oneself as a material object. I will argue that if we accept the assumptions required to show that physical self-ascriptions are IEM, then IEM cannot play the role it needs to play in these anti-Cartesian arguments. (shrink)

In this contribution, we address the issues concerning the semantic value of Wittgenstein’s subject “I”, as in “I have a toothache”, resulting from the use of predicates that involve first-person knowledge of the mental states to which they refer. As is well-known, these contexts give rise to the phenomenon of ‘immunity to error through misidentification’ : the utterer of cannot be mistaken as to whether he is the person having a toothache. We provide a series of (...) arguments in favor of a principled distinction between a de facto IEM, grounded in perceptual and proprioceptive judgments, and a de iure IEM, grounded in experience reports whereby the experience wears the experiencer on its sleeve. From this perspective, the no-referent account of subject “I” advocated by Wittgenstein/Anscombe is correct. In fact, we show how this analysis can be made compatible with a Kaplanian account of first-person indexicals, by identifying the speaker in the context of utterance with the person who has access to the reported private experience.

The thesis addresses the issues of error through misidentification and immunity to error through misidentification in relation to the problem of the first person. First, it provides an explanation of error through misidentification. Secondly, it shows that there are two possible ways of understanding immunity to error through misidentification. It is then argued that the first understanding of immunity to error through misidentification (...) leads to what is labelled "the trilemma about the self". That is to say, either we provide an explanation of immunity to error through misidentification, but we subscribe to two contentious metaphysical views about the self-the Cartesian and the Idealist; or else we hold the view that the self is identical with a human being, but we have no explanation of immunity to error through misidentification. It is then shown that in order to solve the trilemma, a different understanding of immunity to error through misidentification must be offered. After discussing various possible understandings of immunity to error through misidentification, a sound account of it is finally provided. Moreover, it is shown how non-inferential, introspection-based mental self-ascriptions can comply with it, in such a way that they turn out to be logically immune to error through misidentification. Finally, by drawing on Evans' and Peacocke's accounts of the possession conditions of the first person concept-in which IEM I-judgements play a central role-, it is shown that it is a concept of a human being who thinks of herself as such. Hence, our first person concept is firmly anti-Cartesian and anti-Idealist. As a consequence, it is maintained that not only is there no need to hold the Cartesian and the Idealist metaphysics of the self in order to explain why some I-judgements can be immune to error through misidentification, but it is also argued that one can no longer be either Cartesian or Idealist. For that would expose one to conceptual incoherence. (shrink)

This paper offers several new insights into the epistemology of immunity to error through misidentification, by refining James Pryor’s distinction between de re misidentification and wh-misidentification. This is crucial for identifying exactly what is at issue in debates over the Immunity thesis that, roughly, all introspection-based beliefs about one’s own occurrent psychological states are immune to error through misidentification. I contend that the debate between John Campbell and Annalisa Coliva over (...) whether the phenomenon of thought insertion provides empirical evidence against claims like Immunity has wrongly focused on de re misidentification and largely overlooked the role of wh-misidentification. I argue that, once we properly distinguish the two notions, subjects of thought insertion can be seen to make an error of wh-misidentification in their judgments. I argue that this disproves the Immunity thesis, properly understood, and show what broader implications this has for our understanding of IEM and the first person. (shrink)

Sidney Shoemaker credits Wittgenstein’s Blue Book with identifying a special kind of immunity to error that is characteristic of ‘I’ in its “use as subject”. This immunity to error is thought by Shoemaker, and by many following him, to be central to the meaning of ‘I’ and thus to the topics of self-knowledge, self-consciousness and personal memory. This paper argues that Wittgenstein’s work does not contain the thesis, nor any version of the thesis, that there is (...) a use of ‘I’—‘use as subject’—which is ‘immune to error through misidentification’. It offers an interpretative corrective and shows that the passage in question is part of a deep challenge to IEM and to accounts of first-person thought that begin with the idea that there are two uses of the word ‘I’. With the corrective in place novel perspectives on the relation between self-consciousness and subjectivity become visible. (shrink)

The paper explores the idea that some singular judgements about the natural numbers are immune to error through misidentification by pursuing a comparison between arithmetic judgements and first-person judgements. By doing so, the first part of the paper offers a conciliatory resolution of the Coliva-Pryor dispute about so-called “de re” and “which-object” misidentification. The second part of the paper draws some lessons about what it takes to explain immunity to error through misidentification. (...) The lessons are: First, the so-called Simple Account of which-object immunity to error through misidentification to the effect that a judgement is immune to this kind of error just in case its grounds do not feature any identification component fails. Secondly, wh-immunity can be explained by a Reference-Fixing Account to the effect that a judgement is immune to this kind of error just in case its grounds are constituted by the facts whereby the reference of the concept of the object which the judgement concerns is fixed. Thirdly, a suitable revision of the Simple Account explains the de re immunity of those arithmetic judgements which are not wh-immune. These three lessons point towards the general conclusion that there is no unifying explanation of de re and wh-immunity. (shrink)

The aim of this paper is twofold. First, we clarify the notion of immunity to error through misidentification with respect to the first-person pronoun. In particular, we set out to dispel the view that for a judgment to be IEM it must contain a token of a certain class of predicates. Rather, the importance of the IEM status of certain judgments is that it teaches us about privileged ways of coming to know about ourselves. We then (...) turn to examine how perception, as a state with nonconceptual content, can give rise to judgments that are IEM. On one view, the ‘inheritance model’ of immunity, perception gives rise to such judgments because perception itself is IEM. We argue that this model is misguided, and, instead, suggest and elucidate an alternative view: perception gives rise to judgments that are IEM by virtue of containing implicitly self-related or self-concerning information. (shrink)

First person judgments that are immune to error through misidentifi cation (IEM) are fundamental to self-conscious thought. The IEM status of many such judgments can be understood in terms of the possession conditions of the concepts they involve. However, this approach cannot be extended to first person judgments based on autobiographical memory. Th e paper develops an account of why such judgments have the IEM property and how thinkers are able to exploit this fact in inference.

I argue for the following claims: [1] all uses of I are absolutely immune to error through misidentification relative to I. [2] no genuine use of I can fail to refer. Nevertheless [3] I isn’t univocal: it doesn’t always refer to the same thing, or kind of thing, even in the thought or speech of a single person. This is so even though [4] I always refers to its user, the subject of experience who speaks or thinks, (...) and although [5] if I’m thinking about something specifically as myself, I can’t fail to be thinking of myself, and although [6] a genuine understanding use of I always involves the subject thinking of itself as itself, whatever else it does or doesn’t involve, and although [7] if I take myself to be thinking about myself, then I am thinking about myself.

This reviews Simon Prosser's and Francois Recenati's (eds.) 2012 Immunity to Error Through Misidentification: New Essays.

One broadly recognised characteristic feature of (a core subset of) the self-attributions constitutive of self-knowledge is that they are ‘immune to error through misidentification’ (hereafter IEM). In the last thirty years, Evans’s notion of “identification-freedom” (Evans 1982) has been central to most classical approaches to IEM. In the Evansian picture, it is not clear, however, whether there is room for a description of what may be the strongest and most interesting variant of IEM; namely what Pryor (1999) (...) has first brought to the fore under the name “Which-object IEM”, and which I’ll prefer calling existential IEM. I argue that recent development of relativist frameworks in semantics and pragmatics, particularly in Recanati (2007a-b), (2009), (2010), (2012a), may be precisely of a nature to address this limitation. The relativist theory of IEM, and in particular its suitability to cover existential IEM, may superficially seem to stem from a rejection of the core elements of the classical identification-freedom approach. However, I hope to show that, modulo a clarification and richer un-derstanding of the relevant notions of identification and identification-freedom, the relativist theory of IEM can be seen as both pushing further and complementing Evans’s intuitions, rather than conflicting with them.

In this paper I want to examine a claim made about the kind of immunity through misidentification relative to the first person (IEM) that attaches to action self-ascriptions. In particular, I want to consider whether we have reason to think a stronger kind of immunity attaches to action self-ascriptions, than attaches to self-ascriptions of bodily movement. I assume we have an awareness of our actions – agent’s awareness – and that agent’s awareness is not a form (...) of perceptual bodily awareness. The issue here is whether agents’ awareness grounds a kind of immunity to error that bodily awareness does not. However, perhaps more importantly, I want to argue that we only get a secure difference in immunity claims if have already decided whether a source of information is essentially first personal or not and made certain, not obviously warranted assumptions, about the transparency of content and about knowledge. If we hold that a subject’s knowledge of her actions is essentially first personal, in a way that a subject’s knowledge of her body through bodily awareness may not be, then we are better off arguing for that claim directly. Or so I will suggest. (shrink)

Higginbotham argued that certain linguistic items of English, when used in indirect discourse, necessarily trigger first-personal interpretations. They are: the emphatic reflexive pronoun and the controlled understood subject, represented as PRO. PRO is special, in this respect, due to its imposing obligatory control effects between the main clause and its subordinates ). Folescu & Higginbotham, in addition, argued that in Romanian, a language whose grammar doesn’t assign a prominent role to PRO, de se triggers are correlated with the subjunctive mood (...) of certain verbs. That paper, however, didn’t account for the grammatical diversity of the reports that display immunity to error through misidentification in Romanian: some of these reports are expressed by using de se triggers; others are not. Their IEM, moreover, is not systematically lexically controlled by the verbs, via their theta-roles; it is, rather, determined by the meaning of the verbs in question. Given the data from Romanian, I will argue, the phenomenon of IEM cannot be fully explained starting either from the syntactical or the lexical structure of a language. (shrink)

Suppose that the following describes an intelligible scenario. A subject is wired up to another's body in such a way that she has bodily experiences ‘as from the inside’ caused by states and events in the other body, that are subjectively indistinguishable from ordinary somatosensory perception of her own body. The supposed intelligibility of such so-called crossed wire cases constitutes a significant challenge to the claim that our somatosensory judgements are immune to error through misidentification relative to (...) uses of the first person pronoun. After all, the subject in this case is liable to commit precisely the sort of error ruled out by such a claim. In this paper I argue that the proponent of this challenge must establish at least two things: that the subject is committing an error of misidentification, and that her judgement shares its epistemic grounds with our ordinary somatosensory judgements. Neither condition, I argue, can be reached from the stipulations permitted into the starting descriptions of the cases. (shrink)

Sydney Shoemaker argues that a certain class of self-ascriptions is immune to error through misidentification relative to the first-person pronouns. In their “Self-Consciousness and Immunity,” Timothy Lane and Caleb Liang question Shoemaker’s view. Lang and Liang present a clinical case and an experiment and argue that they are counterexamples to Shoemaker’s view. This paper is a response to Lane and Liang’s challenge. I identify the desiderata that a counterexample to Shoemaker’s view must meet and show that (...) somatoparaphrenia and the Body Swap Illusion fail to meet those desiderata. Thus, despite being puzzling phenomena, somatoparaphrenia and the Body Swap Illusion are not counterexamples to Shoemaker’s view. (shrink)

Each of us enjoys a special awareness of (some) of her mental states. The adverbial model of first-person awareness claims that to be aware of a mental state is for it to be conscious, where ‘conscious’ describes the kind of state it is, rather than denoting a form of awareness directed at it. Here, I present an argument for construing first-person awareness of intentions adverbially, by showing that this model can meet a serious challenge posed by the simulation hypothesis, which (...) draws on data about schizophrenia.
