Are occurrent states of forgetting literal experiences of absences? I situate this question within the debate on mental time travel (MTT) to understand whether these states can be explained as literal experiences of absent episodic memories. To frame my argument, I combine Barkasi and Rosen’s literal approach to MTT with Farennikova’s literal approach to the perception of absences, showing that both are built on the idea that for an experience to be literal it must afford an unmediated contact with the (...) object that constitutes it. I test the idea that forgetting affords literal experiences of mnemonic absences by considering different views of absence perception and I evaluate whether the objections raised against Farennikova’s approach also apply to my exploratory idea. I show that, while the idea resists the objections that an advocate of a cognitive approach to mnemonic absences may raise, the same does not apply to those elaborated by advocates of a metacognitive approach. Even if conceiving of occurrent states of forgetting as literal experiences of mnemonic absences sounds appealing, this idea is misleading. Therefore, I suggest conceiving of occurrent states of forgetting as states with metacognitive features, which track the absence of episodic memories from awareness in an affectively mediated way.

Remembering and forgetting are the two poles of the memory system. Consequently, any approach to memory should be able to explain both remembering and forgetting in order to gain a comprehensive and insightful understanding of the memory system. Can an enactive approach to memory processes do so? In this article I propose a possible way to provide a positive answer to this question. In line with some current enactive approaches to memory, I suggest that forgetting –similarly to remembering– might be (...) constituted within an embodied and active process. Within this process, some simulation and re-enactment paths would acquire more relevance than others. This acquired relevance would make the activation of other paths of recall less likely, thus preventing the memory system from engaging in some episodic simulations. These changes in the likelihood of activation of some paths of recall –the forgotten ones– can be accounted for in an enactive fashion by studying both “internal” and “external” re-enactment and simulation paths. With regard to the latter, I propose to examine the process of forgetting by considering the engagement and affective relation of an embodied agent with her field of affordances. I suggest that, in the case of emotion-laden memories, the agent’s decoupling from some affordances of the environment might contribute to the process of forgetting, in that it would reduce the agent’s opportunities for situated episodic simulations.

Patient RB has a peculiar memory impairment wherein he experiences his memories in rich contextual detail, but claims to not own them. His memories do not feel as if they happened to him. In this paper, I provide an explanatory model of RB’s phenomenology, the self-attentional model. I draw upon recent work in neuroscience on self-attentional processing and global workspace models of conscious recollection to show that RB has a self-attentional deficit that inhibits self-bias processes in broadcasting the contents of (...) episodic memories to the global workspace. Typically, self-related contents enjoy a higher salience level than other-related contents. Elimination of bias toward self-related contents diminishes the salience of those contents to the level of other-related contents. Because the typical high salience of self-related content is necessary for the feeling of ownership, RB lacks the feeling of ownership. I also discuss potential applications of the self-attentional model to other psychopathological cases. (shrink)

The discovery of the engram, the physical substrate of memory, is a central challenge for the sciences of memory. Following the application of optogenetics to the neurobiological study of memory, scientists and philosophers claim that the engram has been found. In this paper, I evaluate the implications of applying optogenetic tools to the localization of the engram. I argue that conceptions of engram localization need to be revised to be made consistent with optogenetic studies of the engram. I distinguish between (...) challenges to vehicle and content localization. First, I consider the silent engram hypothesis. According to this hypothesis, optogenetic studies indicate that synaptic efficacy, the traditional engram-bearing vehicle, is important merely for retrieval. I argue that this interpretation rests upon a misunderstanding of accessibility. Second, I argue that optogenetic-based strategies and findings conflict with preservationist and constructivist views on memory storage. There is an enduring trace, but stored content may change over time and experience, resulting in doubt about what constitutes a single engram. (shrink)

Is there a difference between recollecting episodes from the past and recalling autobiographically? Both in the philosophical and psychological literature, it does not seem that there is a consensus on whether autobiographical memories should be considered as a metaphysically equivalent concept to episodic memories or a different category of memory entirely. In this article, I give reasons to believe that autobiographical memories do not relate to the recollection of past episodes since they do not have an associated subjective experience and (...) the consequential experience of mental time travel. Autobiographical memories, I argue, are presented as a narrative that is constructed propositionally, thus differing substantially from episodic memory in its subjective property, the reference to the self, and the content in which each one is grounded. To do so, first I use data from the psychological literature on amnesic patients as evidence for both the difference in phenomenology and content. And second, I use insights from recent philosophical literature on memory and the self, to defend that what is referred here as “autobiographical memory” is indeed a different kind of memory that differs substantially from episodic memory and slightly from semantic memory.

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.

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)

Communities often respond to traumatic events in their histories by destroying objects that would cue memories of a past they wish to forget and by building artefacts which memorialize a new version of their history. Hence, it would seem, communities cope with change by spreading memory ignorance so to allow new memories to take root. This chapter offers an account of some aspects of this phenomenon and of its epistemological consequences. Specifically, it is demonstrated in this chapter that collective forgetfulness (...) is harmful. Here, the focus is exclusively on the harms caused by its contribution to undermining the intellectual self-trust of some members of the community. Further, since some of these harms are also wrongs, collective amnesia contributes to causing epistemic injustices. (shrink)

Many Individuals currently identified within the academic world as ‘“professional” philosophers’ spend a great deal of time arguing about the meaning of their discipline. The situation has recently become so critical that the Cambridge Dictionary of Philosophy, for example, self-consciously excludes the term ‘philosophy’ from its list of entries. An outsider might get the impression that members of the profession suffer from a recurrent kind of intellectual amnesia and need constantly to be reminded about who they are and what their (...) function is.

Why do major historical events such as the Holocaust occupy the forefront of the collective consciousness, while profound moments such as the Armenian genocide, the McCarthy era, and France's role in North Africa stand distantly behind? Is it possible that history "overly remembers" some events at the expense of others? A landmark work in philosophy, Paul Ricoeur's _Memory, History, Forgetting_ examines this reciprocal relationship between remembering and forgetting, showing how it affects both the perception of historical experience and the production (...) of historical narrative. _Memory, History, Forgetting_, like its title, is divided into three major sections. Ricoeur first takes a phenomenological approach to memory and mnemonical devices. The underlying question here is how a memory of present can be of something absent, the past. The second section addresses recent work by historians by reopening the question of the nature and truth of historical knowledge. Ricoeur explores whether historians, who can write a history of memory, can truly break with all dependence on memory, including memories that resist representation. The third and final section is a profound meditation on the necessity of forgetting as a condition for the possibility of remembering, and whether there can be something like happy forgetting in parallel to happy memory. Throughout the book there are careful and close readings of the texts of Aristotle and Plato, of Descartes and Kant, and of Halbwachs and Pierre Nora. A momentous achievement in the career of one of the most significant philosophers of our age, _Memory, History, Forgetting_ provides the crucial link between Ricoeur's _Time and Narrative_ and _Oneself as Another_ and his recent reflections on ethics and the problems of responsibility and representation. “His success in revealing the internal relations between recalling and forgetting, and how this dynamic becomes problematic in light of events once present but now past, will inspire academic dialogue and response but also holds great appeal to educated general readers in search of both method for and insight from considering the ethical ramifications of modern events.... It is indeed a master work, not only in Ricoeur’s own vita but also in contemporary European philosophy.”—_Library Journal _“Ricoeur writes the best kind of philosophy—critical, economical, and clear.”— _New York Times Book Review _.

Just as speech can be acquired, so can it be lost. Speakers can forget words, phrases, even entire languages they once knew; over the course of time peoples, too, let go of the tongues that were once theirs, as languages disappear and give way to the others that follow them. In Echolalias, Daniel Heller-Roazen reflects on the many forms of linguistic forgetfulness, offering a far-reaching philosophical investigation into the persistence and disappearance of speech. In twenty-one brief chapters, he moves among (...) classical, medieval, and modern culture, exploring the interrelations of speech, writing, memory, and oblivion.Drawing his examples from literature, philosophy, linguistics, theology, and psychoanalysis, Heller-Roazen examines the points at which the transience of speech has become a question in the arts, disciplines, and sciences in which language plays a prominent role. Whether the subject is Ovid, Dante, or modern fiction, classical Arabic literature or the birth of the French language, structuralist linguistics or Freud's writings on aphasia, Heller-Roazen considers with clarity, precision, and insight the forms, the effects, and the ultimate consequences of the forgetting of language. In speech, he argues, destruction and construction often prove inseparable. Among peoples, the disappearance of one language can mark the emergence of another; among individuals, the experience of the passing of speech can lie at the origin of literary, philosophical, and artistic creation.From the infant's prattle to the legacy of Babel, from the holy tongues of Judaism and Islam to the concept of the dead language and the political significance of exiled and endangered languages today, Echolalias traces an elegant, erudite, and original philosophical itinerary, inviting us to reflect in a new way on the nature of the speaking animal who forgets.

Some theorists, ranging from W. James to contemporary psychologists, have argued that forgetting is the key to proper functioning of memory. The authors elaborate on the notion of beneficial forgetting by proposing that loss of information aids inference heuristics that exploit mnemonic information. To this end, the authors bring together 2 research programs that take an ecological approach to studying cognition. Specifically, they implement fast and frugal heuristics within the ACT-R cognitive architecture. Simulations of the recognition heuristic, which relies on (...) systematic failures of recognition to infer which of 2 objects scores higher on a criterion value, demonstrate that forgetting can boost accuracy by increasing the chances that only 1 object is recognized. Simulations of the fluency heuristic, which arrives at the same inference on the basis of the speed with which objects are recognized, indicate that forgetting aids the discrimination between the objects' recognition speeds.

In this paper we argue that autobiographical memory can be conceptualized as a mental state resulting from the interplay of a set of psychological capacities?self-reflection, self-agency, self-ownership and personal temporality?that transform a memorial representation into an autobiographical personal experience. We first review evidence from a variety of clinical domains?for example, amnesia, autism, frontal lobe pathology, schizophrenia?showing that breakdowns in any of the proposed components can produce impairments in autobiographical recollection, and conclude that the self-reflection, agency, ownership, and personal temporality are (...) individually necessary and jointly sufficient for autobiographical memorial experience. We then suggest a taxonomy of amnesic disorders derived from consideration of the consequences of breakdown in each of the individual component processes that contribute to the experience of autobiographical recollection.

Referring to a past that never was, dij vu shares a structure not only with fiction, but also with the ever more sophisticated effects of media technology. Tracing the term from the end of the nineteenth century, when it was first popularized in the pages of the Revue philosophique, Peter Krapp examines the genealogy and history of the singular and unrepeatable experience of dij vu. This provocative book offers a refreshing counterpoint to the clichid celebrations of cultural memory and forces (...) us do a double take on the sanctimonious warnings against forgetting so common in our time. Disturbances of cultural memory-screen memories, false recognitions, premonitions-disrupt the comfort zone of memorial culture: strictly speaking, dij vu is neither a failure of memory nor a form of forgetting. Krapp's analysis of such disturbances in literature, art, and mass media introduces, historicizes, and theorizes what it means to speak of an economy of attention or distraction. Reaching from the early psychoanalytic texts of Sigmund Freud to the plays of Heiner M]ller, this exploration of the effects of dij vu pivots around the work of Walter Benjamin and includes readings of kitsch and aura in Andy Warhol's work, of cinematic violence and certain exaggerated claims about shooting and cutting, of the memorial character of architecture, and of the high expectations raised by the Internet. Peter Krapp, lecturer in the Department of Cultural Studies and Comparative Literature at the University of Minnesota, coedited "Medium Cool," a special issue of the South Atlantic Quarterly on contemporary media theory. He has published in the fields of German studies, media studies, and literary theoryand, since 1995, has acted as editor of the Hydra Web site for theories of literature and media. (shrink)

The belief that memory is essential to the self is common. Extreme amnesia, e.g., Korsakoff Syndrome, is held to dissolve the afflicted person’s self. This belief is a misconception that rests on a confusion of epistemic with ontological relevance. Epistemically, memory is relevant to the self: a subject’s self-knowledge partly depends on memories of past experiences. However, it is not by virtue of these memories that the subject is a self: ontologically, memory is irrelevant to that status. The fact that (...) an individuals conception of herself as existing through time is wanting does not prevent that individual from being a self at a given point in time. As the past is there whether or not it is remembered, so the self is there whether or not it remembers. If instead we define the self as awareness of being a subject of experience, the self may survive even the most extreme forms of amnesia. Being a self is an important social value, a prerequisite of numerous legal or moral rights. This in itself is questionable, like the social exclusion it may entail. Denying an amnesic person a self is therefore more than a logical mistake: it is a social exclusion that can also be questioned on ethical grounds. (shrink)

Traumatic stress and its impact on the individual, family and society have been described in the literature for over one hundred years. Controversy exists regarding etiology, determinants and therapeutic intervention for traumatic stress. There is limited research regarding the comparative value of treatment of trauma. In 1989 Eye Movement Desensitization and Reprocessing emerged as a therapeutic intervention for traumatic stress. Studies have shown the benefits of EMDR to be equal to or superior to those of other therapies in the treatment (...) of PTSD. To date, the value of EMDR has been measured primarily by the decrease or amelioration of symptoms. Limited research has focused on the client's experience of EMDR and life changes after EMDR. The specific aim of this study was to: generate a description of the personal experience of the EMDR process, identify whether life changes had occurred after EMDR, and if any life changes had occurred describe the changes and the nature of these changes. Data were collected via unstructured interviews with seven individuals who had experienced some form of trauma, and who had experienced EMDR as a therapeutic intervention for trauma. van Manen's and Heidegger's interpretive processes were used to guide the method of data analysis. The shared meanings identified were: Set-up for Harm, Being Stuck, Willing to Risk in Spite of..., Release, Movement and Ongoing Movement. The participants all described childhood events of being put in harms way. As adults participants felt frustrated with their inability to change personal and relational alienation which resulted from the childhood events. However, in spite of incredulity and fears, risking the experience of EMDR was primarily dependent on trust in the therapist. All experienced emotional, cognitive and physical release in response to the EMDR experience which allowed participants to move forward with their lives. (shrink)
