There are a number of premises underlying much of the vigorous debate on pharmacological cognitive enhancement. Among these are claims in the enhancement literature that such drugs exist and are effective among the cognitively normal. These drugs are deemed to enhance cognition specifically, as opposed to other non-cognitive facets of our psychology, such as mood and motivation. The focus on these drugs as cognitive enhancers also suggests that they raise particular ethical questions, or perhaps more pressing ones, compared to those (...) raised by other kinds of neuroenhancement. Finally, the use of these drugs is often claimed to be significant and increasing. Taken together, these premises are at the heart of the flurry of debate on pharmacological cognitive enhancement. In this article, it is argued that these are presumptions for which the evidence does not hold up. Respectively, the evidence for the efficacy of these drugs is inconsistent; neurologically it makes little sense to distinguish the cognitive from non-cognitive as separate targets of pharmacological intervention; ethically, the questions raised by cognitive enhancement are in fact no different from those raised by other kinds of neuroenhancement; and finally the prevalence rates of these drugs are far from clear, with the bulk of the claims resting on poor or misrepresented data. Greater conceptual clarity along with a more tempered appreciation of the evidence can serve to deflate some of the hype in the associated literature, leading to a more realistic and sober assessment of these prospective technologies.

Wittgenstein finished part 1 of the Philosophical Investigations in the spring of 1945. From 1946 to 1949 he worked on the philosophy of psychology almost without interruption. The present two-volume work comprises many of his writings over this period. Some of the remarks contained here were culled for part 2 of the Investigations ; others were set aside and appear in the collection known as Zettel . The great majority, however, although of excellent quality, have hitherto remained unpublished. This bilingual (...) edition of the Remarks on the Philosophy of Psychology presents the first English translation of an essential body of Wittegenstein's work. It elaborates Wittgenstein's views on psychological concepts such as expectation, sensation, knowing how to follow a rule, and knowledge of the sensations of other persons. It also shows strong emphasis on the "anthropological" aspect of Wittgenstein's thought. Philosophers, as well as anthropologists, psychologists, and sociologists will welcome this important publication. (shrink)

Neil Levy argues that the degree to which psychopaths ought to be held blameworthy for their actions depends on the extent to which they are capable of mental time travel—episodic memory and episodic foresight. Levy claims that deficits in mental time travel prevent psychopaths from fully appreciating what it is to be a person, and, without this understanding, we can at best hold psychopaths blameworthy for harming non-persons. In this paper, I build upon and clarify various aspects of Levy’s view. (...) Specifically, I begin by outlining the neurobiological data on mental time travel, and I argue that psychopaths, or at least some psychopaths, appear to have the deficits Levy ascribes to them. I then expand upon the legal implications of his argument by using an analogy between juveniles and psychopaths to argue that the penological justification for retributive punishment against psychopaths ought to be substantially diminished.

[Michael Tye] Externalism about thought contents has received enormous attention in the philosophical literature over the past fifteen years or so, and it is now the established view. There has been very little discussion, however, of whether memory contents are themselves susceptible to an externalist treatment. In this paper, I argue that anyone who is sympathetic to Twin Earth thought experiments for externalism with respect to certain thoughts should endorse externalism with respect to certain memories. /// [Jane Heal] Tye claims (...) that an externalist should say that memory content invoking natural kind concepts floats free of the setting where the memory is laid down and is at later times determined by the context in which the memory is revived. His argument assumes the existence of 'slow switching' of the meaning of natural kind terms when a person is transported from Earth to Twin Earth. But proper understanding of natural kind terms suggests that slow switching is likely never to be completed. Hence the situation of a person unknowingly transported to Twin Earth is not that his memories switch content but rather that he gets two natural kinds confused. (shrink)

The Routledge International Handbook of Memory Studies offers students and researchers original contributions that comprise the debates, intersections and future courses of the field. It is divided in six themed sections: 1)Theories and Perspectives, 2) Cultural artefacts, Symbols and Social practices, 3) Public, Transnational, and Transitional Memories 4) Technologies of Memory, 5) Terror, Violence and Disasters, 6) and Body and Ecosystems. A strong emphasis is placed on the interdisciplinary breadth of Memory Studies with contributions from leading international scholars in sociology, (...) anthropology, philosophy, biology, film studies, media studies, archive studies, literature and history. The Handbook addresses the core concerns and foundations of the field while indicating new directions in Memory Studies. (shrink)

Research on linguistic interaction suggests that two or more individuals can sometimes form adaptive and cohesive systems. We describe an “alignment system” as a loosely interconnected set of cognitive processes that facilitate social interactions. As a dynamic, multi-component system, it is responsive to higher-level cognitive states such as shared beliefs and intentions (those involving collective intentionality) but can also give rise to such shared cognitive states via bottom-up processes. As an example of putative group cognition we turn to transactive memory (...) and suggest how further research on alignment in these cases might reveal how such systems can be genuinely described as cognitive. Finally, we address a prominent critique of collective cognitive systems, arguing that there is much empirical and explanatory benefit to be gained from considering the possibility of group cognitive systems, especially in the context of small-group human interaction. (shrink)

Wegner, Giuliano, and Hertel (1985) defined the notion of a transactive memory system (TMS) as a group level memory system that “involves the operation of the memory systems of the individuals and the processes of communication that occur within the group (p. 191). Those processes are the collaborative procedures (“transactions”) by which groups encode, store, and retrieve information that is distributed among their members. Over the past 25+ years, the conception of a TMS has progressively garnered an increased interest among (...) social and organizational psychologists, communication scholars, and management theorists (Ren & Argote 2011). But there remains considerable disagreement about how exactly Wegner’s appeal to group memory should be understood. My goal in this paper is contribute to this debate, by articulating more clearly the value of conceptualizing groups as TMSs. This value, I argue, consists in providing us with a blueprint for how to explain group memory in terms of collective information-processing mechanisms. Collective information-processing mechanisms are dependent on, and interact with, the brain-bound information-processing of individuals, but cannot be reduced to the latter. In my analysis, I lean on extant accounts of mechanistic explanation in the philosophy of science (Bechtel & Richardson 1993; Machamer, Darden, & Craver 2000; Wimsatt 2007) that have been used to analyze the explanatory practices of psychology and cognitive neuroscience (Bechtel 2008, 2009). Based on my reconstruction of Wegner’s conceptualization of a TMS, I argue that the reality of emergent group cognition is compatible with its mechanistic explanation. More generally, my analysis shows that group cognition cannot be reduced to individual cognition, while avoiding the false dilemma between “wholism” and “nothing but-ism” which has hampered traditional construals of the “group mind” thesis (Allport 1968).

A woman is listening to Sinatra before work. As she later describes it, ‘suddenly from nowhere I could hear my mother singing along to it … I was there again home again, hearing my mother … God knows why I should choose to remember that … then, to actually hear her and I had this image in my head … of being at home … with her singing away … like being transported back you know I got one of those (...) … like shivery feelings really suddenly’ (Anderson 2004, 9-10). An older couple, discussing their honeymoon forty years ago, each say that they can’t remember the show they saw, until through iterative, puzzled cross-cuing they finally get there – ‘Desert Song, that’s it’ (Harris et al 2011, 292). An elderly English veteran of a prisoner of war camp in Japan, finishing up morning tea with a young Japanese social scientist interested in reconciliation, suddenly calls out loudly - in Japanese - ‘stand to attention’. He stands to attention in front of her: like many of the men she interviews, he physically re-enacts fragments of that long-past world of the camp, bringing that absent past into this new present context with a visceral shock (Murakami 2001, 2012; Middleton & Brown 2005, 133-136).

Sometimes I remember my past experiences from an ‘observer’ perspective, seeing myself in the remembered scene. This paper analyses the distinction in personal memory between such external observer visuospatial perspectives and ‘field’ perspectives, in which I experience the remembered actions and events as from my original point of view. It argues that Richard Wollheim’s related distinction between centred and acentred memory fails to capture the key phenomena, and criticizes Wollheim’s reasons for doubting that observer ‘memories’ are genuine personal memories. Since (...) field perspectives in personal memory are also likely to be the product of constructive processes, we should reject the common assumption that such constructive processes inevitably bring distortion and error. Yet field perspectives tend to be treated as privileged also in the domains of memory for skilled movement, and memory for trauma. In each case, it is argued that visuospatial perspective in personal memory should be distinguished from other kinds of perspective such as kinesthetic perspective and emotional perspective.

On the extended mind hypothesis (EM), many of our cognitive states and processes are hybrids, unevenly distributed across biological and nonbiological realms. In certain circumstances, things - artifacts, media, or technologies - can have a cognitive life, with histories often as idiosyncratic as those of the embodied brains with which they couple. The realm of the mental can spread across the physical, social, and cultural environments as well as bodies and brains. My independent aims in this chapter are: first, to (...) describe two compatible but distinct movements or "waves" within the EM literature, arguing for the priority of the second wave (and gesturing briefly toward a third); and, second, to defend and illustrate the interdisciplinary implications of EM as best understood, specifically for historical disciplines, by sketching two case studies.

In a dynamic world, mechanisms allowing prediction of future situations can provide a selective advantage. We suggest that memory systems differ in the degree of flexibility they offer for anticipatory behavior and put forward a corresponding taxonomy of prospection. The adaptive advantage of any memory system can only lie in what it contributes for future survival. The most flexible is episodic memory, which we suggest is part of a more general faculty of mental time travel that allows us not only (...) to go back in time, but also to foresee, plan, and shape virtually any specific future event. We review comparative studies and find that, in spite of increased research in the area, there is as yet no convincing evidence for mental time travel in nonhuman animals. We submit that mental time travel is not an encapsulated cognitive system, but instead comprises several subsidiary mechanisms. A theater metaphor serves as an analogy for the kind of mechanisms required for effective mental time travel. We propose that future research should consider these mechanisms in addition to direct evidence of future-directed action. We maintain that the emergence of mental time travel in evolution was a crucial step towards our current success. (shrink)

Abstract Temporal Externalism is the view that future events can contribute to determining the present content of our thoughts and utterances. Two objections to Temporal Externalism are discussed and rejected. The first is that Temporal Externalism has implausible consequences for the epistemology of biology and other taxonomic sciences (Brown, 2000). The second is that it is committed to implausible claims about dispositions.

This paper discusses two perspectives, each of which recognises the importance of environmental resources in enhancing and amplifying our cognitive capacity. One is the Clark–Chalmers model, extended further by Clark and others. The other derives from niche construction models of evolution, models which emphasise the role of active agency in enhancing the adaptive fit between agent and world. In the human case, much niche construction is epistemic: making cognitive tools and assembling other informational resources that support and scaffold intelligent action. (...) I shall argue that extended mind cases are limiting cases of environmental scaffolding, and while the extended mind picture is not false, the niche construction model is a more helpful framework for understanding human action.

In what respects is episodic recollection active, and subject to the will, like perceptual imagination, and in what respects is it passive, like perception, and how do these matters relate to its epistemological role? I present an account of the ontology of episodic recollection that provides answers to these questions. According the account I recommend, an act of episodic recollection is not subject to epistemic evaluation—it is neither justified nor unjustified—but it can provide one with a distinctive source of warrant (...) for judgements about the past when it is accompanied by knowledge that one is recollecting, as well as knowledge of what one is recollecting. While the account concedes that when one recollects one's attitude to what is recollected cannot be one of observation, it nevertheless accommodates the notion that episodic recollection involves a form of mental time-travel—a case of re-visiting, or re-acquaintance with, some past episode.

This article explores the notion of the Web-extended mind, which is the idea that the technological and informational elements of the Web can sometimes serve as part of the mechanistic substrate that realizes human mental states and processes. It is argued that while current forms of the Web may not be particularly suited to the realization of Web-extended minds, new forms of user interaction technology as well as new approaches to information representation do provide promising new opportunities for Web-based forms (...) of cognitive extension. In addition, it is suggested that extended cognitive systems often rely on the emergence of social practices and conventions that shape how a technology is used. Web-extended minds may thus depend on forms of socio-technical co-evolution in which social forces and factors play just as important a role as do the processes of technology design and development.

In this paper we examine C. I. Lewis's view on the roleof coherence – what he calls ''congruence'' – in thejustification of beliefs based on memory ortestimony. Lewis has two main theses on the subject. His negativethesis states that coherence of independent items ofevidence has no impact on the probability of a conclusionunless each item has some credibility of its own. Thepositive thesis says, roughly speaking, that coherenceof independently obtained items of evidence – such asconverging memories or testimonies – raises (...) the probabilityof a conclusion to the extent sufficient for epistemicjustification, or, to use Lewis's expression, ''rationaland practical reliance''.It turns out that, while thenegative thesis is essentially correct, astrong positive connection between congruence andprobability – a connection of the kind Lewis ultimatelyneeds in his validation of memory – is contingent on thePrinciple of Indifference. In the final section we assess therepercussions of the latter fact for Lewis's theory in particularand for coherence justification in general. (shrink)

Sosa (2007) claims that a necessary condition on knowledge is manifesting an epistemic competence. To manifest an epistemic competence, a belief must satisfy two conditions: (1) it must derive from the exercise of a reliable belief-forming disposition in appropriate conditions for its exercise and (2) that exercise of the disposition in those conditions would not issue a false belief in a close possible world. Drawing on recent psychological research, I show that memories that are issued by episodic memory retrieval fail (...) to satisfy either of these conditions. This presents Sosa, and other proponents of similar conditions (e.g. some safety theorists and process reliabilists), with a dilemma: (1) deny that episodic memories count as knowledge or (2) give up the conditions as necessary conditions on knowledge. I explore the implications of this dilemma for our understanding of knowledge, memory and the relationship between them. (shrink)

In this paper I argue that internalistic foundationalist theories of the justification of memory belief are inadequate. Taking a discussion of John Pollock as a starting point, I argue against any theory that requires a memory belief to be based on a phenomenal state in order to be justified. I then consider another version of internalistic foundationalism and claim that it, too, is open to important objections. Finally, I note that both varieties of foundationalism fail to account for the epistemic (...) status of our justified nonoccurrent beliefs, and hence are drastically incomplete. (shrink)

In this essay, I consider a kind of social group that I call ‘epistemic’. It is constituted by its members’ possession of perceptually grounded common knowledge, which endows them with a particular kind of epistemic authority. This authority, I argue, is invoked in the activity of ‘joint reminiscing’—of remembering together a past jointly experienced event. Joint reminiscing, in turn, plays an important role in the constitution of social and personal identity. The notion of an epistemic group, then, is a concept (...) that helps explain an important aspect of a subject’s understanding of who she is. (shrink)

Among the many topics covered in Sven Bernecker’s impressive study of memory is the relation between memory and personal identity. Bernecker uses his grammatical taxonomy of memory and causal account to defend the claim that memory does not logically presuppose personal identity and hence that circularity objections to memory-based accounts of personal identity are misplaced. In my comment I investigate these claims, suggesting that the relation between personal identity and memory is more complicated than Bernecker’s analysis suggests. In particular, I (...) argue that while he shows that some memories do not presuppose personal identity he fails to show that those that are appealed to in memory-based accounts of personal identity do not, and that the features of his view that allow him to define memory without reference to personal identity also obscure important features of memory that must be part of a complete account.

Preservationism is a dominant account of the justification of beliefs formed on the basis of memory. According to preservationism, a memory belief is justified only if that belief was justified when it was initially held. However, we now know that much of what we remember is not explicitly stored, but instead reconstructed when we attempt to recall it. Since reconstructive memory beliefs may not have been continuously held by the agent, or never held before at all, a purely preservationist account (...) of memory does not allow for justified reconstructed memory beliefs. In this essay, I show how a process reliabilist account can maintain preservationism about reproductive memory beliefs while accommodating the justification of reconstructive memory beliefs. I argue that reconstructive memory is an inferential process, and that therefore the beliefs it produces are justified in the same way that other inferential beliefs are justified. Accordingly, my process reliabilist account combines a preservationist account of reproductive memory with an inferential account of reconstructive memory. I end by defending this view against objections. (shrink)

This paper identifies a form of remembering sufficiently overlooked that it has not yet been dignified with a name. I shall christen it Rilkean Memory. This form of memory is, typically, embodied and embedded. It is a form of involuntary, autobiographical memory that is neither implicit nor explicit, neither declarative nor procedural, neither episodic nor semantic, and not Freudian. While a discussion of the importance of Rilkean memory lies beyond the scope of this paper, I shall try to show that (...) admitting Rilkean memory into our ontology does point us in the direction of a very different conception of the mind and mental processes.

K.C. has been investigated extensively over some 20 years since a motorcycle accident left him with widespread brain damage that includes large bilateral hippocampal lesions, which caused a remarkable case of memory impairment. On standard testing, K.C.'s anterograde amnesia is as severe as that of any other case reported in the literature, including H.M. However, his ability to make use of knowledge and experiences from the time before his accident shows a sharp dissociation between semantic and episodic memory. A good (...) deal of his general knowledge of the world, including knowledge about himself, is preserved, but he is incapable of recollecting any personally experienced events. In displaying such “episodic amnesia,” which encompasses an entire lifetime of personal experiences, K.C. differs from many other amnesic cases. Here, we document for the first time the full extent of K.C.'s brain damage using MRI-based quantitative measurements. We then review the many investigations with K.C. that have contributed to our understanding not only of episodic and semantic memory but also to the development of other aspects of memory theory. These include the distinction between implicit and explicit memory, the prospect of new learning in amnesia, and the fate of recent and remote memory for autobiographical and public events, people, and spatial locations.

During the past decade there has been a very effective campaign against any explanation of remembering whose basic concept is that of a causally mediating trace. This paper attempts to provide such an explanation by presenting an explicit deductive argument for the existence of the memory trace. The conclusion is shown to follow from reasonable, empirical assumptions of which the most interesting is a spatiotemporal contiguity thesis. Set-theoretic techniques are used to provide a framework of analysis and probabilistic definitions of (...) some causal notions, as that of a causal chain, are presented. (shrink)

According to the Causal Theory of Memory, remembering a particular past event requires a causal connection between that event and its subsequent representation in memory, specifically, a connection sustained by a memory trace. The CTM is the default view of memory in contemporary philosophy, but debates persist over what the involved memory traces must be like. Martin and Deutscher argued that the CTM required memory traces to be structural analogues of past events. Bernecker and Michaelian, contemporary CTM proponents, reject structural (...) analogues in favor of memory traces as distributed patterns of event features. The proposals are understood as distinct accounts of how memory traces represent past events. But there are two distinct questions one could ask about a trace’s representational features. One might ask how memory traces, qua mental representations, have their semantic properties. Or, what makes memory traces, qua mental representations of memories, distinct from other mental representations. Proponents of the CTM, both past and present, have failed to keep these two questions distinct. The result is a serious but unnoticed problem for the CTM in its current form. Distributed memory traces are incompatible with the CTM. Such traces do not provide a way to track the causal history of individual memories, as the CTM requires. If memory traces are distributed patterns of event features, as Bernecker and Michaelian each claim, then the CTM cannot be right. (shrink)

The Archival and Constructive views of memory offer contrasting characterizations of remembering and its relation to memory errors. I evaluate the descriptive adequacy of each by offering a close analysis of one of the most prominent experimental techniques by which memory errors are elicited—the Deese-Roediger-McDermott paradigm. Explaining the DRM effect requires appreciating it as a distinct form of memory error, which I refer to as misremembering. Misremembering is a memory error that relies on successful retention of the targeted event. It (...) differs from both successful remembering and from confabulation errors, where the representation produced is wholly inaccurate. As I show, neither the Archival nor the Constructive View can account for the DRM effect because they are insensitive to misremembering’s unique explanatory demands. Fortunately, the explanatory limitations of the Archival and Constructive Views are complementary. This suggests a way.. (shrink)

Confabulation is a symptom central to many psychiatric diagnoses and can be severely debilitating to those who exhibit the symptom. Theorists, scientists, and clinicians have an understandable interest in the nature of confabulation—pursuing ways to define, identify, treat, and perhaps even prevent this memory disorder. Appeals to confabulation as a clinical symptom rely on an account of memory’s function from which cases like the above can be contrasted. Accounting for confabulation is thus an important desideratum for any candidate theory of (...) memory. Many contemporary memory theorists now endorse Constructivism, where memory is understood as a capacity for constructing plausible representations of past events. Constructivism’s aim is to account for and normalize the prevalence of memory errors in everyday life. Errors are plausible constructions that, on a particular occasion have led to error. They are not, however, evidence of malfunction in the memory system. While Constructivism offers an uplifting repackaging of the memory errors to which we are all susceptible, it has troubling implications for appeals to confabulation in psychiatric diagnosis. By accommodating memory errors within our understanding of memory’s function, Constructivism runs the risk of being unable to explain how confabulation errors are evidence of malfunction. After reviewing the literature on confabulation and Constructivism, respectively, I identify the tension between them and explore how different versions of Constructivism may respond. The paper concludes with a proposal for distinguishing between kinds of false memory—specifically, between misremembering and confabulation—that may provide a route to their reconciliation. (shrink)

Stanley Klein and Shaun Nichols describe the case of patient R.B., whose memories lacked the sense of “mineness” usually conveyed by memory. Klein and Nichols take R.B.’s case to show that the sense of mineness is merely a contingent feature of memory, which they see as raising two problems for memory-based accounts of personal identity. First, they see it as potentially undermining the appeal of memory-based accounts. Second, they take it to show that the conception of quasi-memory that underpins many (...) memory-based accounts is inadequate. I argue that Klein and Nichols’ characterization of R.B.’s experience is implausible; as a result, the problems that they describe for memory-based accounts of personal identity do not arise.

Is it conceptually possible for one person to ‘remember’ the experiences of another person? Many philosophical discussions of personal identity suppose that this is possible. For example, some philosophers believe that our personal identity through time consists in the continuation of our mental lives, including the holding of memories over time. However, since a person’s memories are necessarily memories of her own experiences, a definition of personal identity in terms of memory risks circularity. To avoid this, we must invoke the (...) concept of ‘quasi-memory’. From my quasi-memory of doing x, I cannot infer that I did x; but I can infer that somebody did x. It is then a further question as to whether the person who did x is me, the answer to which will depend upon what we believe personal identity to consist in. Quasi-memory, then, allows us to separate the concept of memory from the concept of personal identity. (shrink)

_A leading contrarian thinker explores the ethical paradox at the heart of history's wounds_ The conventional wisdom about historical memory is summed up in George Santayana’s celebrated phrase, “Those who cannot remember the past are condemned to repeat it.” Today, the consensus that it is moral to remember, immoral to forget, is nearly absolute. And yet is this right? David Rieff, an independent writer who has reported on bloody conflicts in Africa, the Balkans, and Central Asia, insists that things are (...) not so simple. He poses hard questions about whether remembrance ever truly has, or indeed ever could, “inoculate” the present against repeating the crimes of the past. He argues that rubbing raw historical wounds—whether self-inflicted or imposed by outside forces—neither remedies injustice nor confers reconciliation. If he is right, then historical memory is not a moral imperative but rather a moral option—sometimes called for, sometimes not. Collective remembrance can be toxic. Sometimes, Rieff concludes, it may be more moral to forget. Ranging widely across some of the defining conflicts of modern times—the Irish Troubles and the Easter Uprising of 1916, the white settlement of Australia, the American Civil War, the Balkan wars, the Holocaust, and 9/11—Rieff presents a pellucid examination of the uses and abuses of historical memory. His contentious, brilliant, and elegant essay is an indispensable work of moral philosophy. (shrink)

Although episodic memory is a widely studied form of memory both in philosophy and psychology, it still raises many burning questions regarding its definition and even its acceptance. Over the last two decades, cross-disciplinary discussions between these two fields have increased as they tackle shared concerns, such as the phenomenology of recollection, and therefore allow for fruitful interaction. This editorial introduction aims to provide a comprehensive and up-to-date presentation of the main existing conceptions and issues on the topic. After delineating (...) Tulving’s chief theoretical import and multifaceted legacy, it goes on to chart the different attempts to capture the episodicity feature of memory according to three categories: a first approach aims to show the cognitive abilities required for a subject to episodically remember; the second defines episodicity as a stage-specific feature; the last explains episodicity in terms of the epistemological properties of episodic memory. This state of the art thereby sets the stage for the contributions of the present volume, which will be introduced in conclusion. (shrink)

Challenging, with several powerful arguments, some of our deepest beliefs about rationality, morality, and personal identity, Parfit claims that we have a false view about our own nature. It is often rational to act against our own best interersts, he argues, and most of us have moral views that are self-defeating. We often act wrongly, although we know there will be no one with serious grounds for complaint, and when we consider future generations it is very hard to avoid conclusions (...) that most of us will find very disturbing.

"Quasi-memories," necessarily presupposing a distinction between an "experiencing" and a "remembering" person, are considered by Parfit and Shoemaker as necessary and/or sufficient criteria for personal identity. However, the concept of "q-memories" is rejected by Schechtman since, according to her, neither "content" and "experience" can be separated from each other in "q-memories" ("principal inseparability") nor can they be distinguished from delusions/confabulations ("principal indistinguishability"). The purpose of the present paper is to demonstrate that, relying on a neurophilosophical approach, both arguments can be (...) rejected. Neuropsychological research shows that "contents" of memories are classified according to the accompanying psychological state such that the same "content" can be classified either as auto- or heterobiographical by the respective "experience." Since "content" and "experience" can be separated from each other, the argument of "principal inseparability" must be rejected on empirical grounds. In addition, as demonstrated in an example of a schizophrenic patient, "q-memories" can be distinguished from delusions/confabulations considering the ability to distinguish between different sources of autobiographical memories as a differential criterion. In conclusion, both arguments by Schechtman against the concept of "q-memories" have to be rejected on the basis of neurophilosophical considerations. Consequently, the concept of "q-memories" can be considered as compatible with current empirical knowledge. (shrink)

For cases in which to remember that p is to have (strict) nonbasic, unmixed memory knowledge that p; in which there is at most one prior time, t, from which one remembers; in which one knew at t that p; and in which there can arise a sensible question whether one remembers that p from t — a person, B, remembers that p from t if and only if: (1) There is a set of grounds a subset of which consists (...) of (i) only those grounds B has at both t and the present for B to be sure that p, and (ii) enough such grounds to make it reasonable at both t and the present for B to be sure that p (I call any such subset a set of “adequate original grounds dating from t”), and (2) there is no time prior to t such that B has a set of adequate original grounds dating from that time. The way in which the crucial terms in this explication are being used is explained. And the explication is defended by showing how it can deal with cases that are counterexamples to explications recently offered by Malcolm and by Munsat. (shrink)
