Theories of Memory

The Hard Question of memory is the following: how are memory representations stored and organized so as to be made available for retrieval in the appropriate circumstances and format? In this essay, I argue that philosophical theories of memory should engage with the Hard Question directly and seriously. I propose that declarative memory is a faculty performing a kind of cognitive triage: management of information for a variety of uses under significant computational constraints. In such triage, memory representations are preferentially (...) selected and stabilized, but also systematically modified and integrated into generalized, model-like representational structures. Further, I propose a hybrid theory of remembering, which takes into account both the nature of the cognitive processes underlying remembering and the norms that govern representational success in relevant cognitive/epistemic contexts.

The paper explicates and defends a direct realist view of episodic memory as pastperception, on the model of the more prominent direct realism about perception. First, a number of extant allegedly direct realist accounts are critically assessed, then the slogan that memory is past-perception is explained, defended against objections, and compared to extant rival views. Consequently, it is argued that direct realism about memory is a coherent and defensible view, and an attractive alternative to both the mainstream causal theories and (...) the post-causal and constructivist views.

This paper unites current philosophical thinking on imagination with a burgeoning debate in the philosophy of memory over whether episodic remembering is simply a kind of imagining. So far, this debate has been hampered by a lack of clarity in the notion of ‘imagining’ at issue. Several options are considered and constructive imagining is identified as the relevant kind. Next, a functionalist account of episodic memory is defended as a means to establishing two key points: first, one need not defend (...) a factive (or “causalist”) view of remembering in order to hold that causal connections to past experiences are essential to how rememberings are typed; and, second, current theories that equate remembering with imagining are in fact consistent with a functionalist theory that includes causal connections in its account of what it is to remember. This suggests that remembering is not a kind of imagining and clarifies what it would take to establish the contrary. (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)

This paper aims to provide a psychologically-informed philosophical account of the phenomenology of episodic remembering. The literature on epistemic or metacognitive feelings has grown considerably in recent years, and there are persuasive reasons, both conceptual and empirical, in favour of the view that the phenomenology of remembering—autonoetic consciousness, as Tulving influentially referred to it, or the feeling of pastness, as we will refer to it here—is an epistemic feeling, but few philosophical treatments of this phenomenology as an epistemic feeling have (...) so far been proposed. Building on insights from the psychological literature, we argue that a form of feeling-based metacognition is involved in episodic remembering and develop an integrated metacognitive feeling-based view that addresses several key aspects of the feeling of pastness, namely, its status as a feeling, its content, and its relationship to the first-order memories the phenomenology of which it provides.

This paper explores the relationship between a prominent version of the relational view of memory and recent work on forms of unsuccessful remembering or memory errors. I argue that unsuccessful remembering poses an important challenge for the relational view. Unsuccessful remembering can be divided into two kinds: misremembering and confabulating. I discuss each of these cases in light of a recent relational account, according to which remembering is characterized by an experiential relation to past events, and I argue that experiential (...) relations do not adequately distinguish between successful and unsuccessful remembering. This is because there are, on the one hand, cases of remembering that do not instantiate the relevant experiential relations, and, on the other hand, cases of confabulation and misremembering that do instantiate the relevant experiential relations. I conclude by suggesting that any successful relationalist attempt to explain remembering needs to come to grips with unsuccessful remembering. (shrink)

Os realistas diretos sobre a memória episódica alegam que um sujeito que lembra está em contato direto com um evento passado. No entanto, como seria possível estar em contato direto com um evento que deixou de existir? Este é o assim-chamado problema da cotemporalidade. A solução padrão para este problema, a qual foi proposta por Sven Bernecker, consiste em distinguir entre, por um lado, a ocorrência de um evento, e, por outro lado, a existência de um evento, de modo que (...) um evento deixa de ocorrer sem deixar de existir – esta é a solução eternista para o problema da cotemporalidade. No entanto, alguns filósofos da memória – notadamente Kourken Michaelian – alegam que a adoção de uma metafísica eternista do tempo seria um preço metafísico muito alto a ser pago para se defender as intuições dos realistas diretos sobre a memória. Ainda que eu concorde com essas críticas, buscarei mostrar duas coisas. Primeiro, que este tipo de “argumento do senso comum” não é decisivo. Segundo, que a proposta de Bernecker permanece sendo a melhor solução para o problema da cotemporalidade. (shrink)

It seems natural to think that emotional experiences associated with a memory of a past event are new and present emotional states triggered by the remembered event. This common conception has nonetheless been challenged at the beginning of the 20th century by intellectuals who considered that emotions can be encoded and retrieved, and that emotional aspects linked to memories of the personal past need not necessary to be new emotional responses caused by the act of recollection. They called this specific (...) kind of memories “affective memories” and defended their existence. My aim here is to expound the historical background of this debate as well as the characterization and development of the notion of affective memory since its first inception. I aim to show that although the debate was left unresolved and the term disappeared from academy around 1930, many of the characterizations of the nature of emotions and memory done by the advocates of affective memory have reappeared in the scientific agenda and been further developed during the last decades.

In the philosophy of memory, singularism is the view that episodic memories are singular mental states about unique personally experienced past events. In this paper, I present an empirical challenge to singularism. I examine three distinct lines of evidence from the psychology of memory, concerning general event memories, the transformation of memory traces and the minimized role temporal information plays in major psychological theories of episodic memory. I argue that singularist views will have a hard time accommodating this evidence, facing (...) a problem of transitional gradation. I then look at some potential consequences for the larger debate, highlighting the way in which singularism has featured in three important recent arguments in the philosophy of memory. (shrink)

O presente artigo busca situar o leitor em alguns dos debates atuais acerca da memória episódica no âmbito da filosofia da memória. A memória episódica consiste na capacidade de lembrar daquilo que o sujeito vivenciou ao longo de sua vida. Um dos maiores problemas em filosofia da memória é estabelecer o que é uma memória episódica, e distingui-la de outros estados mentais, como a imaginação. As principais teorias que visam resolver tal problema são a Teoria Causal da Memória e a (...) Teoria Simulacionista da Memória. Causalistas insistem que deve haver um vínculo causal entre uma experiência vivida pelo sujeito no passado e a memória dessa experiência. Simulacionistas, em contrapartida, sustentam que tal vínculo causal não é necessário, pois uma memória é o resultado de um processo de simulação que combina elementos de várias memórias para formar um cenário que representa a experiência passada. Outro debate em filosofia da memória trata dos objetos da memória episódica, nele busca-se descobrir com o quê entramos em contato quando lembramos de um evento passado. Nesse debate as posições filosóficas mais defendidas são o Realismo Indireto e o Realismo Direto; o primeiro afirma que entramos em contato com representações do evento passado, já o último sustenta que entramos em contato diretamente com o evento passado. Esse artigo apresenta também teorias da psicologia sobre consolidação de memórias episódicas e a teoria da Mental Time Travel, afim de embasar o leitor, respectivamente, acerca dos mecanismos formadores da memória e do debate sobre a função da memória episódica.

In this paper, I describe how artifacts and autobiographical memory are integrated into new systemic wholes, allowing us to remember our personal past in a more reliable and detailed manner. After discussing some empirical work on lifelogging technology, I elaborate on the dimension of autobiographical dependency, which is the degree to which we depend on an object to be able to remember a personal experience. When this dependency is strong, we integrate information in the embodied brain and in an object (...) to reconstruct an autobiographical memory. In such cases, autobiographical memory is extended or distributed. (shrink)

This paper responds to Bernecker’s attack on Michaelian’s simulationist account of confabulation, as well as his defence of the causalist account of confabulation :432–447, 2016a) against Michaelian’s attack on it. The paper first argues that the simulationist account survives Bernecker’s attack, which takes the form of arguments from the possibility of unjustified memory and justified confabulation, unscathed. It then concedes that Bernecker’s defence of the causalist account against Michaelian’s attack, which takes the form of arguments from the possibility of veridical (...) confabulation and falsidical relearning, is partly successful. This concession points the way, however, to a revised simulationist account that highlights the role played by failures of metacognitive monitoring in confabulation and that provides a means of distinguishing between “epistemically innocent” and “epistemically culpable” memory errors. Finally, the paper responds to discussions by Robins and Bernecker of the role played by the concept of reliability in Michaelian’s approach, offering further considerations in support of simulationism.

This paper proposes a novel account of the contents of memory. By drawing on insights from the philosophy of perception, I propose a hybrid account of the contents of memory designed to preserve important aspects of representationalist and relationalist views. The hybrid view I propose also contributes to two ongoing debates in philosophy of memory. First, I argue that, in opposition to eternalist views, the hybrid view offers a less metaphysically-charged solution to the co-temporality problem. Second, I show how the (...) hybrid view conceives of the relationship between episodic memory and other forms of episodic thinking. I conclude by considering some disanalogies between perception and memory and by replying to objections. I argue that, despite there being important differences between memory and perception, those differences do not harm my project. (shrink)

According to simulationism, the function of episodic memory is not to remember the past, but to help construct representations of possible future episodes, by drawing together features from different experiential sources. This article suggests that the relationship between the traditional storehouse view, on which the function of memory is remembering, and the simulationist approach is more complicated than has been typically acknowledged. This is attributed, in part, to incorrect interpretations of what remembering on the storehouse view requires. Further, by appeal (...) to function pluralism, the article questions both the assumption that the traditional view and simulationism are inconsistent, and the simulationist’s inference to the best explanation strategy that is based upon this assumption. The article then provides an evaluation of the simulationist argument against the traditional view, and finds it in need of further support. (shrink)

Observer memories, memories where one sees oneself in the remembered scene, from-the-outside, are commonly considered less accurate and genuine than visual field memories, memories in which the scene remembered is seen as one originally experienced it. In Remembering from the Outside (OUP, 2019), Christopher McCarroll debunks this commonsense conception by offering a detailed analysis of the nature of observer memories. On the one hand, he explains how observer and field perspectives are not really mutually exclusive in an experience, including memory (...) experiences. On the other hand, he argues that in observer memories there is no additional explicit representation of oneself experiencing the event: the self-presence is transparent and given by the mode of presentation. Whereas these are two lines of strategic and original argumentation, they are not exempt of problems. In this critical notice, I focus on the problematic aspects of McCarroll’s account. I show that it presents some issues that affect the internal coherence of the overall framework, and that some aspects and central notions would have needed more development to offer a precise picture of the nature of observer memories.

The paper develops an account of minimal traces devoid of representational content and exploits an analogy to a predictive processing framework of perception. As perception can be regarded as a prediction of the present on the basis of sparse sensory inputs without any representational content, episodic memory can be conceived of as a “prediction of the past” on the basis of a minimal trace, i.e., an informationally sparse, merely causal link to a previous experience. The resulting notion of episodic memory (...) will be validated as a natural kind distinct from imagination. This trace minimalist view contrasts with two theory camps dominating the philosophical debate on memory. On one side, we face versions of the Causal Theory that hold on to the idea that episodic remembering requires a memory trace that causally links the event of remembering to the event of experience and carries over representational content from the content of experience to the content of remembering. The Causal Theory, however, fails to account for the epistemic generativity of episodic memory and is psychologically and information-theoretically implausible. On the other side, a new camp of simulationists is currently forming up. Motivated by empirical and conceptual deficits of the Causal Theory, they reject not only the necessity of preserving representational content, but also the necessity of a causal link between experience and memory. They argue that remembering is nothing but a peculiar form of imagination, peculiar only in that it has been reliably produced and is directed towards an episode of one’s personal past. Albeit sharing their criticism of the Causal Theory and, in particular, rejecting its demand for an intermediary carrier of representational content, the paper argues that a causal connection to experience is still necessary to fulfill even the minimal requirements of past-directedness and reliability.

This essay investigates the notion of simulation and the role it plays in Kourken Michaelian's simulation theory of memory. I argue that the notion is importantly ambiguous and that this ambiguity may threaten some of the central commitments of the theory. To illustrate that, I examine two different conceptions of simulation: a narrow one (simulation as replication) and a broad one (simulation as computational modeling), arguing that the preferred narrow conception is incompatible with the claim that remembering involves the simulation (...) of past episodes. Investigating possible solutions, I suggest that, despite some relatively serious consequences, the theory may be better off subscribing to the broad notion of simulation. (shrink)

This paper aims to reconfigure the place of memory in epistemology. I start by rethinking the problem that memory systems solve; rather than merely functioning to store information, I argue that the core function of any memory system is to support accurate and relevant retrieval. This way of specifying the function of memory has consequences for which structures and mechanisms make up a memory system. In brief, memory systems are modeling systems. This means that they generate, update and manage a (...) series of overlapping, simplified, relational representations that map out features of the world. Succeeding at building and maintaining models requires the kind of active knowledge generation traditionally associated only with deliberative reasoning. (shrink)

I argue that the function of episodic memory is to store information about the past, against the orthodox view that it is to support imagining the future. I show that episodic memory is epistemically generative, allowing organisms to learn from past events retroactively. This confers adaptive benefits in three domains: reasoning about the world, skill, and social interaction. Given the role of evolutionary perspectives in comparative research, this argument necessitates a radical shift in the study of episodic memory in nonhumans.

Episodic memory (EM) involves re-experiencing past experiences by means of mental imagery. Aphantasics (who lack mental imagery) and people with severely deficient autobiographical memory (SDAM) lack the ability to re-experience, which would imply that they don't have EM. However, aphantasics and people with SDAM have personal and affective memories, which are other defining aspects of EM (in addition to re-experiencing). This suggests that these supposed aspects of EM really are independent faculties or modules of memory, and that EM is a (...) composite faculty rather than a natural kind. Apparent varieties of (normal and "defective") EM (as well as some closely related kinds of memory) are different combinations of these modules, and the EM construct itself adds little if any explanatory value to these modules.

In his brief treatment of memory, Hume characterizes memory using two kinds of criteria: ideas’ phenomenal character and their correspondence to the past experiences from which they derived. These criteria have seemed so perplexing to interpreters, both individually and jointly, that Hume’s account of memory is commonly considered one of the weakest parts of his philosophical system. This paper defends Hume’s criteria by showing that they achieve two theoretical aims: a scientific classification of ideas and a definition of ‘memory.’ In (...) particular, I argue that Hume’s definition of ‘memory’ is cogent in light of Putnamian considerations about definitions.

Memory is everywhere in Blade Runner 2049. From the dead tree that serves as a memorial and a site of remembrance (“Who keeps a dead tree?”), to the ‘flashbulb’ memories individuals hold about the moment of the ‘blackout’, when all the electronic stores of data were irretrievably erased (“everyone remembers where they were at the blackout”). Indeed, the data wiped out in the blackout itself involves a loss of memory (“all our memory bearings from the time, they were all damaged (...) in the blackout”). Memory, and lack of it, permeates place, where from the post-blackout Las Vegas Deckard remembers it as somewhere you could “forget your troubles.” Memory is a commodity, called upon and consumed by the Wallace Corporation, purchased from the memory-maker, Dr Ana Stelline, who constructs and implants “the best memories” in replicants so as to instil in them real human responses. Memory is ubiquitous in Blade Runner 2049, involving humans, replicants, objects, and machines. Even “God,” we are told, “remembered Rachael.” Nowhere, though, is the depiction of memory more important than in the attempt to solve a question of identity. Officer K has a memory of his past. Even though he knows it is an implant, it is a memory he is emotionally attached to, frequently narrating it to Joi, his digital girlfriend. But it is a memory that starts to puzzle and trouble him. When K discovers the remains of a dead replicant, a female NEXUS-7, he uncovers a secret—this replicant was pregnant and died during childbirth, a discovery that could “break the world.” K is charged with hunting down the child and making the problem disappear. Yet as K starts seeking answers to the question of the child’s identity he gets inextricably caught up in the mystery. Is he merely Officer K, or is he Joe, the miracle child of Rachael and Deckard? The answer to this question hinges on K’s memory. But is the memory genuine? Is the memory his? Blade Runner 2049 encourages us to think deeply about the nature of memory, identity, and the relation between them. Indeed, the film does not just serve as a starting point for thinking about philosophical issues related to memory and identity. Rather, as we show in this chapter, the film seems to offer a view on these philosophical issues. Blade Runner 2049 offers us a view of memory as spread out over people, objects, and the environment, and it shows us that memory’s role in questions of identity goes beyond merely accurately recalling one’s past. Identity depends not on memory per se, but partly on what we use memory for. (shrink)

I argue that appreciation of the phenomenon of forgetting requires serious attention to its origins and place in nature. This, in turn, necessitates metaphysical inquiry as well as empirical backing – a combination likely to be eschewed by psychological orthodoxy. But, if we hope to avoid the conceptual vacuity that characterizes too much of contemporary psychological inquiry (e.g., Klein, 2012, 2014a, 2015a, 2016a), a “big picture” approach to phenomena of interest is essential. Adopting this investigative posture turns the “received view” (...) of the relation between remembering and forgetting on its head: Rather than treated as the result of breakdowns and limitations of biologically engineered systems of remembering, forgetting is accorded elevated status as the driving force behind the evolution of organic systems of information retention.

Radical enactivism, an increasingly influential approach to cognition in general, has recently been applied to memory in particular, with Hutto and Peeters New directions in the philosophy of memory, Routledge, New York, 2018) providing the first systematic discussion of the implications of the approach for mainstream philosophical theories of memory. Hutto and Peeters argue that radical enactivism, which entails a conception of memory traces as contentless, is fundamentally at odds with current causal and postcausal theories, which remain committed to a (...) conception of traces as contentful: on their view, if radical enactivism is right, then the relevant theories are wrong. Partisans of the theories in question might respond to Hutto and Peeters’ argument in two ways. First, they might challenge radical enactivism itself. Second, they might challenge the conditional claim that, if radical enactivism is right, then their theories are wrong. In this paper, we develop the latter response, arguing that, appearances to the contrary notwithstanding, radical enactivism in fact aligns neatly with an emerging tendency in the philosophy of memory: radical enactivists and causal and postcausal theorists of memory have begun to converge, for distinct but compatible reasons, on a contentless conception of memory traces.

Bringing research on collective memory together with research on episodic future thought, Szpunar and Szpunar :376–389, 2016) have recently developed the concept of collective future thought. Individual memory and individual future thought are increasingly seen as two forms of individual mental time travel, and it is natural to see collective memory and collective future thought as forms of collective mental time travel. But how seriously should the notion of collective mental time travel be taken? This article argues that, while collective (...) mental time travel is disanalogous in important respects to individual mental time travel, the concept of collective mental time travel nevertheless provides a useful means of organizing existing findings, while also suggesting promising directions for future research.

The debate over the objects of episodic memory has for some time been stalled, with few alternatives to familiar forms of direct and indirect realism being advanced. This paper moves the debate forward by building on insights from the recent psychological literature on memory as a form of episodic hypothetical thought (or mental time travel) and the recent philosophical literature on relationalist and representationalist approaches to perception. The former suggests that an adequate account of the objects of episodic memory will (...) have to be a special case of an account of the objects of episodic hypothetical thought more generally. The latter suggests that an adequate account of the objects of episodic hypothetical thought will have to combine features of direct realism and representationalism. We develop a novel pragmatist-inspired account of the objects of episodic hypothetical thought that has the requisite features. (shrink)

In this paper we present a introduction to the volume on philosophy of memory.

Memory is not a unitary phenomenon. Even among the group of long-term individual memory representations (known in the literature as declarative memory) there seems to be a distinction between two kinds of memory: memory of personally experienced events (episodic memory) and memory of facts or knowledge about the world (semantic memory). Although this distinction seems very intuitive, it is not so clear in which characteristic or set of interrelated characteristics lies the difference. In this article, I present the different criteria (...) proposed in the philosophical and scientific literature in order to account for this distinction: (1) the vehicle of representation; (2) the grammar of the verb “to remember”; (3) the cause of the memory; (4) the memory content; and (5) the phenomenology of memory representations. Whereas some criteria seem more plausible than others, I show that all of them are problematic and none of them really fulfill their aim. I then briefly outline a different criterion, the affective criterion, which seems a promising line of research to try to understand the grounds of this distinction. (shrink)

In a recent paper, Cheng and Werning (2016) argue that the class of episodic memories constitutes a natural kind. Endorsing the homeostatic property cluster view of natural kinds, they suggest that episodic memories can be characterized by a cluster of properties unified by an underlying neural mechanism for coding sequences of events. Here, I argue that Cheng & Werning’s proposal faces some significant, and potentially insurmountable, difficulties. Two are described as most prominent. First, the proposal fails to satisfy an important (...) normative constraint on natural kind theorizing, not providing the requisite theoretical resources for arbitration between rival taxonomies of memory. Second, the proposal is in a direct tension with a foundational principle of the HPC view: the rejection of essentialism. This has far-reaching consequences, threatening to undermine the coherence of the proposal. (shrink)

Many philosophers consider that memory is just a passive information retention and retrieval capacity. Some information and experiences are encoded, stored, and subsequently retrieved in a passive way, without any control or intervention on the subject’s part. In this paper, we will defend an active account of memory according to which remembering is a mental action and not merely a passive mental event. According to the reconstructive account, memory is an imaginative reconstruction of past experience. A key feature of the (...) reconstructive account is that given the imperfect character of memory outputs, some kind of control is needed. Metacognition is the control of mental processes and dispositions. Drawing from recent work on the normativity of automaticity and automatic control, we distinguish two kinds of metacognitive control: top-down, reflective control, on the one hand, and automatic, intuitive, feeling-based control on the other. Thus, we propose that whenever the mental process of remembering is controlled by means of intuitive or feeling-based metacognitive processes, it is an action. (shrink)

Descartes held the following view of declarative memory: to remember is to reconstruct an idea that you intellectually recognize as a reconstruction. Descartes countenanced two overarching varieties of declarative memory. To have an intellectual memory is to intellectually reconstruct a universal idea that you recognize as a reconstruction, and to have a sensory memory is to neurophysiologically reconstruct a particular idea that you recognize as a reconstruction. Sensory remembering is thus a capacity of neither ghosts nor machines, but only of (...) human beings qua mind-body unions. This interpretation unifies Descartes’s various remarks (and conspicuous silences) about remembering, from the 1628 Rules for the Direction of the Mind through the suppressed-in-1633 Treatise of Man to the 1649 Passions of the Soul. It also rebuts a prevailing thesis in the current secondary literature—that Cartesian critters can remember—while incorporating the textual evidence for that thesis—Descartes’s detailed descriptions of the corporeal mechanisms that construct sensory memories.

Thomas Reid offers an explanation of how memory of events is possible. This paper presents, criticize,s and amends his view that memory not only preserves our knowledge of the external world, but also contributes to such knowledge, by being essential for the perception of events. Reid’s views on memory are in line with his generalanti-skeptical commitments, and thus attractive, for several reasons. One reason is that, just like perception, memory is not infallible, but it can constitute or, at least, ground (...) knowledge. Reid argues that memory, like perception, is immediate: it gives direct access to the external world, and not to mental representations of the external world. Another reason is that Reid’s explanation of how memory of events works emphasizes the impor- tance of the divide between memory and perception and consciousness: it is one thing to perceive or be conscious of something; it is another to remember that thing. Despite these advantages, a careful study of Reid’s views on memory will uncover a serious problem of general philosophical interest: it is unclear how exactly we are able to remember events episodically, since it is not settled whether we ever literally perceive events. This problem is engendered by a clash of the following two intuitions: (i) we can perceive only presently existing things, and (ii) we can remember events, which usually span periods of time longer than the present (whether the present is durationless or not). (shrink)

Thomas Reid believed that the human mind is well equipped, from infancy, to acquire knowledge of the external world, with all its objects, persons and events. There are three main faculties that are involved in the acquisition of knowledge: (original) perception, memory, and imagination. It is thought that we cannot understand how exactly perception works, unless we have a good grasp on Reid’s notion of perceptual conception (i.e., of the conception employed in perception). The present paper argues that the same (...) is true of memory, and it offers an answer to the question: what type of conception does it employ? (shrink)

Forgetting is importantly related to remembering, evidence possession, epistemic virtue, personal identity, and a host of highly-researched memory conditions. In this paper I examine the nature of forgetting. I canvass the viable options for forgetting’s ontological category, type of content, characteristic relation to content, and scale. I distinguish several theories of forgetting in the philosophy and psychology of memory literatures, theories that diverge on these options. The best theories from the literature, I claim, fail two critical tests that I develop (...) (the metacognition and prospection tests), underwriting arguments against the theories. I introduce a new theory about the state of forgetting—the learning, access failure, dispositional (LEAD) theory: to forget is to fail to access something that is both learned and either inaccessible or intended to be accessed. I argue that the LEAD theory of forgetting is the lead theory of forgetting. It passes the metacognition and prospection tests, and has several further virtues at no cost. Finally, I advocate reductionism about the process of forgetting; the process reduces wholly to states of forgetting. In particular, a process of forgetting is just a sequence of increasingly strong states of forgetting. (shrink)

There seems to be a distinctive way in which we can remember events we have experienced ourselves, which differs from the capacity to retain information about events that we can also have when we have not experienced those events ourselves but just learned about them in some other way. Psychologists and increasingly also philosophers have tried to capture this difference in terms of the idea of two different types of memory: episodic memory and semantic memory. Yet, the demarcation between episodic (...) memory and semantic memory remains a contested topic in both disciplines, to the point of there being researchers in each of them who question the usefulness of the distinction between the two concepts. In this paper, I outline a new characterization of the difference between episodic memory and semantic memory, which connects that difference to what is sometimes called the ‘epistemic asymmetry’ between the past and the future, or the ‘epistemic arrow’ of time. My proposal will be that episodic memory and semantic memory exemplify the epistemic asymmetry in two different ways, and for somewhat different reasons, and that the way in which episodic memory exemplifies the epistemic asymmetry is manifest to the remembering subject in a way in which this is not the case for semantic memory. (shrink)

In the literature on episodic memory, one claim that has been made by a number of psychologists, and that is also at least implicit in some of the accounts given by philosophers, is that being able to recollect particular past events in the distinctive way afforded by episodic memory requires the possession of aspects of a theory of mind, such as a grasp of the relationship between one’s present recollective experience and one’s own past perceptual experience of the remembered event. (...) In this paper, I re-examine what connection, if any, there is between episodic memory and theory of mind. I first criticize the dominant way in which this connection has been construed theoretically, which – perhaps influenced by other aspects of theory of mind research – has sought to link the possession of episodic memory primarily with a grasp of the idea of representation, or the idea of informational access. I then argue for a novel, alternative, way of connecting episodic memory and theory of mind, which focuses on the category of an experience, and on the role a grasp of that category might be seen to play in episodic recollection. In doing so, I also draw attention to a dimension of our understanding of the mental which remains as yet underexplored in the literature on theory of mind. (shrink)

What kind of mental state is episodic memory? I defend the claim that it is, in key part, imagining the past, where the imagining in question is experiential imagining. To remember a past episode is to experientially imagine how things were, in a way controlled by one’s past experience of that episode. Call this the Inclusion View. I motive this view by appeal both to patterns of compatibilities and incompatibilities between various states, and to phenomenology. The bulk of the paper (...) defends the account against four objections. Imagining and remembering seem to differ in whether they are active or passive, in the forms of singular content they involve, in their relations to observation and in their relations to belief. I argue that these differences can be accommodated, and some even explained, once we flesh out what else is involved in episodic memory, in addition to imagining the past. (shrink)

This chapter proposes a radically enactive account of remembering that casts it as creative, dynamic, and wide-reaching. It paints a picture of remembering that no longer conceives of it as involving passive recollections – always occurring wholly and solely inside heads. Integrating empirical findings from various sources, the chapter puts pressure on familiar cognitivist visions of remembering. Pivotally, it is argued, that we achieve a stronger and more elegant account of remembering by abandoning the widely held assumption that it is (...) rooted in the retrieval of stored information or content in order to represent past events. We demonstrate how a radically enactive account of the roots of remembering can successfully handle classic cases discussed in the extended memory literature while, at same time, accommodating experientially rich forms of episodic memory.

Episodic memory has been analyzed in a number of different ways in both philosophy and psychology, and most controversy has centered on its self-referential, autonoetic character. Here, we offer a comprehensive characterization of episodic memory in representational terms and propose a novel functional account on this basis. We argue that episodic memory should be understood as a distinctive epistemic attitude taken toward an event simulation. In this view, episodic memory has a metarepresentational format and should not be equated with beliefs (...) about the past. Instead, empirical findings suggest that the contents of human episodic memory are often constructed in the service of the explicit justification of such beliefs. Existing accounts of episodic memory function that have focused on explaining its constructive character through its role in future-oriented mental time travel do justice neither to its capacity to ground veridical beliefs about the past nor to its representational format. We provide an account of the metarepresentational structure of episodic memory in terms of its role in communicative interaction. The generative nature of recollection allows us to represent and communicate the reasons why we hold certain beliefs about the past. In this process, autonoesis corresponds to the capacity to determine when and how to assert epistemic authority in making claims about the past. A domain where such claims are indispensable are human social engagements.

This article builds on ideas presented in Klein (2015a) concerning the importance of a more nuanced, conceptually rigorous approach to the scientific understanding and use of the construct “memory”. I first summarize my model, taking care to situate discussion within the terminological practices of contemporary philosophy of mind. I then elucidate the implications of the model for a particular operation of mind – the manner in which content presented to consciousness realizes its particular phenomenological character (i.e., mode of presentation). Finally, (...) I discuss how the model offers a reconceptualization of the technical language used by psychologists and neuroscientists to formulate and test ideas about memory. (shrink)

Ao nos lembrarmos de ocorrências anteriores, nossa mente se volta para as ocorrências mesmas, as quais outrora foram vivenciadas em primeira pessoa e originaram, naqueles momentos anteriores, sensações e pensamentos?
