This paper defends the claim that, in order to have a concept of time, subjects must have memories of particular events they once witnessed. Some patients with severe amnesia arguably still have a concept of time. Two possible explanations of their grasp of this concept are discussed. They take as their respective starting points abilities preserved in the patients in question: (1) the ability to retain factual information over time despite being unable to recall the past event or situation (...) that information stems from, and (2) the ability to remember at least some past events or situations themselves (typically because retrograde amnesia is not complete). It is argued that a satisfactory explanation of what it is for subjects to have a concept of time must make reference to their having episodic memories such as those mentioned under (2). It is also shown how the question as to whether subjects have such memories, and thus whether they possess a concept of time, enters into our explanation of their actions. (shrink)

Autobiographical–episodic memory is the conjunction of subjective time, autonoetic consciousness and the experiencing self. Understanding the neural correlates of autobiographical–episodic memory might therefore be essential for shedding light on the neurobiology underlying the experience of being an autonoetic self. In this contribution we illustrate the intimate relationship between autobiographical–episodic memory and self by reviewing the clinical and neuropsychological features and brain functional imaging correlates of psychogenic amnesia – a condition that is usually characterized by severely impaired retrograde memory (...) functioning, in absence of structural brain damage as detected by standard imaging. We demonstrate that in this disorder the autobiographical–episodic memory deficits do not exist in isolation, but occur with impairments of the autonoetic self-consciousness, emotional processing, and theory of mind or executive functions. Furthermore functional and metabolic brain alterations involving regions that are agreed upon to exert crucial roles in memory processes were frequently found to accompany the psychogenic memory “loss”.

Within Piaget there is an implicit theory of the development of explicit memory. It rests in the dynamical trajectory underlying the development of causality, object, space and time – a complex (COST) supporting a symbolic relationship integral to the explicit. Cassirer noted the same dependency in the phenomena of aphasias, insisting that a symbolic function is being undermined in these deficits. This is particularly critical given the reassessment of Piaget’s stages as the natural bifurcations of a self-organizing dynamic system. The (...) elements of a theoretical framework required to support explicit memory are developed, to include, (1) the complex developmental trajectory supporting the emergence of the explicit in Piaget, (2) the concrete dynamical system and the concept of a non-differentiable time contained in Bergson’s theory required to support a conscious, as opposed to an implicit remembrance, (3) the relation to current theories of amnesia, difficulties posed by certain retrograde amnesic phenomena, the role of the hippocampus and limitations of connectionist models, (4) the fact that nowhere in this overall framework does the loss of explicit memory imply or require the destruction of experience “stored in the brain.”.

Aggleton & Brown rightly point out the shortcomings of the medial temporal lobe hypothesis as an approach to anterograde amnesia. Their broader perspective is a necessary corrective, and one hopes it will be taken very seriously. Although they correctly note the dangers of conflating recognition and recall, they themselves make a similar mistake in discussing familiarity; we suggest an alternative approach. We also discuss implications of their view for an analysis of retrograde amnesia. The notion that there (...) are two routes by which the hippocampus can reactivate neuronal ensembles in the neocortex could help us understand some currently puzzling facts about the dynamics of memory consolidation.

According to the Psychological Account of personal identity, personal identity across time is maintained by some form of psychological overlap or continuance. I show that the Psychological Account has trouble accommodating cases of transient retrograde amnesia. In such cases, the transitivity of psychological continuity may break down. I consider various means of responding to this problem, arguing that the best available response will undercut our ability to rely on intuitions about brain transplantation to support the Psychological Account. When (...) the Psychological Account is re-interpreted in such a way as to overcome the problems posed by cases of transient retrograde amnesia, it turns out that standard brain transplantation cases involve details which are strictly irrelevant according to the theory. On the other hand, these features seem to drive our intuitions about survival in these cases. In this way, my argument undermines one of the key motivations for adopting the Psychological Account.

_Feminist Amnesia_ is an important challenge to contemporary academic feminism. Jean Curthoys argues that the intellectual decline of university arts education and the loss of a deep moral commitment in feminism are related phenomena. The contradiction set up by the radical ideas of the 1960s, and institutionalised life of many of its protagonists in the academy has produced a special kind of intellectual distortion. This book criticises current trends in feminist theory from the perspective of forgotten and allegedly outdated feminist (...) ideas. Jean Curthroys show that much contemporary feminist theory, like much of today's radical thought, is muddled. The 'forgotten' theory of Women's Liberation was, she argues, deeply oppositional and moral. The repression of this theory has led to distortions, most notabley in the preoccupation with binary oppositions. Jean Curthoys argues that where Women's Liberation was once radical, much of contemporary feminist thought hides behind obscurantism, and has become conservative and orthodox. These controversial ideas will be keenly debated by all those involved in womens's studies, feminist theory and moral philosophy. (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)

By utilizing new information from both clinical and experimental (lesion, electrophysiological, and gene-activation) studies with animals, the anatomy underlying anterograde amnesia has been reformulated. The distinction between temporal lobe and diencephalic amnesia is of limited value in that a common feature of anterograde amnesia is damage to part of an comprising the hippocampus, the fornix, the mamillary bodies, and the anterior thalamic nuclei. This view, which can be traced back to Delay and Brion (1969), differs from other (...) recent models in placing critical importance on the efferents from the hippocampus via the fornix to the diencephalon. These are necessary for the encoding and, hence, the effective subsequent recall of episodic memory. An additional feature of this hippocampalanterior thalamic and the perirhinal–medial dorsal thalamic systems are compromised, leading to severe deficits in both recall and recognition. (shrink)

Alessandra Tanesini is a Professor of Philosophy at Cardiff University working on epistemology and philosophy of language. In this post she summarises some of her recent work on collective amnesia and epistemic injustice.

Barbara Montero considers whether or not we are able to remember what pain feels like. In order to properly answer this question, she introduces a new type of memory called 'qualitative memory', which seems common to exteroceptive sensations. Having concluded that there is arguably no qualitative memory for pain and other bodily sensations, Montero considers possible philosophical implications for areas including rational choice-making and empathy. In addressing the relationship between pain and memory, the paper raises an issue that has not (...) received much attention and indicates various interesting fields of research for which the apparent inability to remember pain might prove relevant. My comment primarily focuses on the core concepts of pain and qualitative memory which are foundational for the paper. I argue that a deeper engagement with some key aspects of these concepts is necessary. A more fine-grained discussion could have made Montero's argument more convincing. (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.

In this paper, I argue that Stanley and Williamson’s 2001 account of knowledge-how as a species of knowledge-that is wrong. They argue that a claim such as “Hannah knows how to ride a bicycle” is true if and only if Hannah has some relevant knowledge-that. I challenge their claim by considering the case of a famous amnesic patient named Henry M. who is capable of acquiring and retaining new knowledge-how but who is incapable of acquiring and retaining new knowledge-that. In (...) the first two sections of the paper, I introduce the topic of knowledge-how and give a brief overview of Stanley and Williamson’s position. In the third and fourth sections, I discuss the case of Henry M. and explain why it is plausible to describe him as someone who can retain new knowledge-how but not new knowledge-that. In the final sections of the paper, I argue that Henry M.’s case does indeed provide a counterexample to Stanley and Williamson’s analysis of knowing-how as a species of knowing-that, and I consider and respond to possible objections to my argument.

Clinical experience suggests that adult survivors of childhood trauma arrive at their memories in a number of ways, with varying degrees of associated distress and uncertainty and, in some cases, after memory lapses of varying duration and extent. Among those patients who enter psychotherapy as a result of early abuse, three general patterns of traumatic recall are identified: relatively continuous and complete recall of childhood abuse experiences coupled with changing interpretations of these experiences, partial amnesia for abuse events, accompanied (...) by a mixture of delayed recall and delayed understanding, and delayed recall following a period of profound and pervasive amnesia. These patterns are represented by three composite clinical vignettes. Variations among them suggest that the phenomena underlying traumatic recall are continuous not dichotomous. Future research into the nature of traumatic memory should be informed by clinical observation. (shrink)

The psychoanalytical case history was in many ways the pivot point of John Forrester’s reflections on case-based reasoning. Yet the Freudian case is not without its own textual forebears. This article closely analyses texts from two earlier case-writing traditions in order to elucidate some of the negotiations by which the case history as a textual form came to articulate the mode of reasoning that we now call ‘thinking in cases’. It reads Eugène Azam’s 1876 observation of Félida X and her (...) ‘double personality’—the case that brought both Azam and Félida to prominence in late 19th-century French science—against a medico-surgical case penned by the Bordeaux physician in the same decade. While the stylistics of Azam’s medical case mirror its epistemic underpinnings in the ‘vertical’ logics of positivist science, the multiple narratives interwoven in Félida’s case grant both Azam and his patient the role of knowledge-making actors in the text. This narrative transformation chimes with the way Azam reasons ‘horizontally’ from particulars to Félida’s singular condition, but sits in tension with his choice to structure the observation along a ‘vertical’ axis. Between the two, we glimpse the emergence of the psychological observation as a mode of writing and thus of thinking in cases. (shrink)

Is a painful experience less bad for you if you will not remember it? Do you have less reason to fear it? These questions bear on how we think about medical procedures and surgeries that use an anesthesia regimen that leaves patients conscious – and potentially in pain – but results in complete ‘drug-induced amnesia’ after the fact. I argue that drug-induced amnesia does not render a painful medical procedure a less fitting object of fear, and thus the (...) prospect of amnesia does not give patients a reason not to fear it. I expose three mistakes in reasoning that might explain our tendency to view pain or discomfort as less fearful in virtue of expected amnesia: a mistaken view of personal identity; a mistaken view of the target of anticipation; and a mistaken method of incorporating past evidence into calculations about future experiences. Ultimately my argument has implications for whether particular procedures are justified and how medical professionals should speak with anxious patients about the prospect of drug-induced amnesia.

Climate justice activists envision a “postcarbon” future that not only transforms energy infrastructures but also redresses the fossil fuel economy’s long-standing racial inequalities. Yet this anti-racist rebranding of the “zero emissions” telos does not tend to the racial grief that’s foundational to white supremacy. Accordingly, I ask: can we address racial oppression through a “just transition” to a “postcarbon” moment? In response, I connect today’s postcarbon imaginary with yesterday’s postcolonial imaginary. Drawing from research on US-based climate activism, I explore how (...) the utopic rhetoric of a “just transition” is instantiated in practice. I argue that the racialized absences constitutive of what scholars call “postcolonial amnesia” are operative in the anti-racist move to a postcarbon moment. This postcarbon imaginary formulates the vulnerability of people of color to biophysical disasters as the raison d’être for infrastructural transformation. This, I argue, has the effect of overlooking the ways in which racial grief inheres in such vulnerability and the capacity of energy infrastructures to uphold racist hierarchies. I situate this “postcarbon amnesia” in Anne Cheng’s framework for differentiating “grief” from “grievance,” calling for renewable energy transitions that move away from enumerative grievances and toward a sobering recognition of racial grief.

The correspondence metaphor is useful in developing functional models of memory. However, the storehouse metaphor is still useful in developing structural and process models of memory. Traditional research techniques explore the structure of memory; everyday techniques explore the function of memory. We illustrate this point with two examples: amnesia and metamemory. In each phenomenon, both metaphors are useful.

Aggleton & Brown have built a convincing case that hippocampus-related circuits may be involved in thalamic amnesia. It remains to be established, however, that their model represents a distinct neurological system, that the distinction between recall and familiarity captures the roles of these pathways in episodic memory, or that there are no other systems that contribute to the signs of amnesia associated with thalamic disease.

Tradicionalmente, a questão da identidade pessoal é considerada a questão a respeito ao que faz uma pessoa ser a mesma ao longo do tempo. Recentemente, porém, atenção à experiência fenomênica trouxe uma nova perspectiva ao debate. À luz dessa mudança de perspectiva, Klein sugere que indivíduos com amnésia episódica retrógrada retêm uma noção de quem são, além de terem senso de continuidade. Ele, portanto, argumenta que a memória episódica não é necessária para se ter sensação de si mesmo diacrônica. Desafiamos (...) a conclusão de Klein apontando que existem tipos mais extremos de amnésia—amnésia psicogênica—que parecem problemáticos à sua proposta de que o senso de continuidade é suficiente para se ter sensação de si mesmo diacrônico. Esse é o caso, porque alguns exemplos de amnésia psicogênica são casos de amnésia dissociativa, que mostram que ter uma experiência consciente contínua não resolve o problema. (shrink)

Dissociative identity disorder (DID; called multiple personality disorder in DSMIII-R) is a psychiatric condition in which two or more identity states recurrently take control of the person's behavior. A characteristic feature of DID is the occurrence of apparently severe amnestic symptoms. This paper is concerned with experimental research of memory function in DID and focuses on between-identity transfer of newly learned neutral material. Previous studies on this subject are reviewed and a pilot study with four subjects is described. This study (...) is specifically concerned with the question whether self-reported asymmetries in between-identity transfer can be replicated on experimental memory tests. A secondary aim was to examine whether, in the absence of explicit transfer, implicit transfer of information would occur. The results showed that the apparent amnestic asymmetry for explicit information was substantiated in the laboratory, although at least some leakage was present between the apparently amnestic identities. No evidence was found for better performance on implicit than on explicit memory tests in the apparently amnestic identities. In the discussion, parallels between apparent amnesia in DID and state-dependent memory are drawn, and the question of simulated amnesia is addressed. (shrink)

Not so very long ago — that is to say during the late sixties and early seventies — most Left lawyers understood the law as an ideological and repressive force imposed upon oppressed individuals, groups and classes from without. Viewed from the eye of the political storm surrounding the antiwar and Black liberation struggles, the conclusion that the law was a prime instrument of ruling class hegemony seemed obvious. Before the bar of progressive opinion, radicals presented their indictment of the (...) entire juridical apparatus of the American state sub nomine the law against the people. The law was dismissed contemptuously as an elaborate structure of myths, the function of which was to obscure the underlying reality of bitter struggle between social classes. (shrink)
