This chapter describes the concept of enactive memory, which is quite new but increasingly discussed in contemporary philosophy of memory. Although the enactive approach has been used to investigate several memory sys- tems, e.g., procedural memory, episodic mem- ory, and autobiographical memory, this chapter focuses only on the enactive approach to epi- sodic memory because most of the current debate on enactive memory is about this mem- ory system. Section “Introduction” specifies what type of enactive memory is discussed in this (...) chapter. Section “The Concept of Enactive Memory” introduces the concept of enactive memory, clarifies its central theoretical com- mitments and goals, and describes how enactivists have explained episodic remember- ing. Section “The Philosophical Context of Enactive Memory” provides a brief contextu- alization of the enactive approach to memory with respect to approaches and theories with which, for one reason or another, it shares some theoretical insights, like the embodied, the extended, and the distributed approach, and the simulation theory. Section “Forgetting as a Challenge for Enactive Memory” explains why forgetting poses an important explanatory challenge to the enactive approach to memory and describes one philosophical proposal that has been developed to address this challenge. Section “Summary” provides a summary of the chapter, mentions some ongoing projects on enactive memory, and identifies some topics that advocates of the enactive approach to memory may want to investigate in the future.

If we are free to imagine what we choose, this is likely because our intentions determine what we are imagining. However, in a recent article, Munro and Strohminger (2021) argue that, in some cases of imagistic imagining, our intentions do not determine what we are imagining. They offer examples where, intuitively, a person intends to imagine one thing but, due to the causal source of the image used, imagine another. This paper acknowledges the challenge posed by these cases while arguing (...) on several grounds that, when present, intentions nevertheless always suffice to determine the object of one’s imaginings. A key claim is that, while we always imagine what we intend, we do not always imagine it as we intended. I conclude by explaining how intentions could fix the objects of episodic rememberings in much the same way as they do for imaginings, thereby bolstering the case that remembering is a kind of imagining.

In the philosophy of memory there is a tension between a preservationist and a constructivist view of memory reflected in the debate between causalism and simulationism. Causalism is not only committed to the claim that there must be an appropriate causal connection between the remembered event and the content represented at retrieval but also that such connection is possible because of a content-preserving memory trace. Simulationism, by contrast, rejects the need for an appropriate causal condition and, thereby, makes the appeal (...) to memory traces unnecessary. In this paper I argue that while the are strong conceptual arguments and empirical evidence to support a constructivist view of memory, the empirical evidence also suggest that the initial formulation of simulationism needs to be revised. In particular, I argue, first, that simulationism’s commitment to a single cognitive system for mental time travel is likely wrong, and second, that simulationism cannot get rid of memory traces altogether, as they are still explanatorily indispensable when it comes to explaining a large number of memory-related phenomena. At the end, I end up suggesting a way of thinking about memory traces that, I think, is compatible with simulationism and a constructivist view of memory. If the view I put forth is on the right track, then an updated version of simulationism can help to dispel the dichotomy between causalism and simulationism as a false one. (shrink)

The (dis)continuism debate—the debate over whether remembering is a form of imagining—is a prominent one in contemporary philosophy of memory. In recent work, Langland-Hassan (2021) has argued that this debate is best understood as a dispute over whether remembering is a form of constructive imagining. In this paper, I argue that remembering is not a form of constructive imagining because constructive processes in remembering and imagining are constrained, and hence controlled, in different ways at the level of consciousness. More specifically, (...) I argue that remembering and imagining differ in terms of the interventions we can make on the constructive processes as they unfold. If this is correct, then a form of discontinuism is vindicated: remembering and imagining are, on this view, processes of different kinds. (shrink)

Originally understood as memory for the “what”, the “when”, and the “where” of experienced past events, episodic memory has, in recent years, been redefined as a form of past-oriented mental time travel. Following a brief review of empirical research on memory as mental time travel, this introduction provides an overview of the contributions to the special issue, which explore the theoretical implications of that research.

Understood as a psychological phenomenon, there has been very little discussion of cryptomnesia in the philosophical literature. Cryptomnesia presents us with a strange phenomenon in which we take ourselves to be imagining, but the thought or idea that we entertain actually involves remembered content. In this paper, we argue for a three-factor account of cryptomnesia, according to which it is a mnemonic phenomenon that involves imagination. We provide an account of both the ‘mnemonic’ and ‘imaginative’ aspects of cryptomnesia in terms (...) of the attitude, the content, and the metacognitive processes involved in those states. In addition, we show how our three-factor account is better suited to account for cryptomnesia than competing philosophical theories of episodic memory. We conclude by discussing how the three-factor account sheds light on a range of other mnemonic and imaginative phenomena. (shrink)

The current dispute between causalists and simulationists in philosophy of memory has led to opposing attempts to characterize the relationship between memory and imagination. In a recent overview of this debate, Perrin and Michaelian have suggested that the dispute over the continuity between memory and imagination boils down to the question of whether a causal connection to a past event is necessary for remembering. By developing an argument based on an analogy to perception, I argue that this dispute should instead (...) be viewed as a dispute about the nature of the attitudes involved in remembering and imagining. The focus on attitudes, rather than on causal connections, suggests a new way of conceiving of the relationship between memory and imagination that has been overlooked in recent philosophy of memory.

The Simulation Theory of Memory states that to remember an episode is to simulate it in the imagination (Michaelian, 2016a, b), making memory thus reducible to the act of imagining. This paper examines Simulation Theory’s resources to account for our ability to distinguish episodic memory from free imagination. The theory suggests that we can reliably do so because of the distinctive phenomenology episodic memory comes with (i.e., a feeling of remembering), which other episodic imaginings lack. I will raise two objections (...) to how the feeling of remembering is engineered in the theory, followed by an exhaustive exploration of the theory’s resources to ground the mechanism underlying the elicitation of such feeling. I will conclude that the Simulation Theory cannot simultaneously defend the simulational character of episodic memory and ground our ability to discriminate between memories and imaginings. (shrink)

Une relation causale appropriée à une scène vécue dans le passé est-elle nécessaire pour qu’une représentation de cette scène en soit le souvenir épisodique? Le présent article expose les réponses qui sont actuellement apportées à ce débat central en philosophie de la mémoire. Il introduit d’abord les conditions définitionnelles avancées par la théorie causale standard, avant d’examiner les critiques qui ont été formulées à leur encontre. L’article présente et discute alors deux familles de théories qui ont été proposées en réaction (...) à ces critiques : les théories causales réformatrices, d’une part, et la théorie anti-causale simulationniste, d’autre part.

I suggest that the theories of remembering one finds in the philosophy of memory literature are best characterised as theories principally operating at three different levels of inquiry. Simulationist views are theories of the psychofunctional process type remembering. Causalist views are theories of referential remembering. Epistemic views are theories of successful remembering. Insofar as there is conflict between these theories, it is a conflict of integration rather than—as widely presented—head‐on disagreement. Viewed in this way, we can see the previous awareness (...) condition and preservationism as principles applying at only some of the corresponding levels of inquiry. Where either principle has been rejected, it is, I claim, due to arguments which slip between these different levels. While the view of the landscape I offer does not dissolve ongoing disputes about the nature of remembering, it clarifies the dialectical rules of engagement, helping to clear the path for future, collaborative progress to be made. The view enables us to see less conflict in the recent philosophy of memory literature than there seems at face value to be. (shrink)

The origin of memories is thought to be found in sensory perception. This conception is central to how the memory sciences characterize encoding. This paper considers how novel memory traces can be formed independently of external sensory inputs. I present a case study in which memory traces are created without sensory perception using a technique I call optogenetic memory implantation. Comparing this artificial process with normal memory encoding, I consider its implications for rethinking the causal chain that leads to remembering.

Mental imagery often occurs during testimonial belief transmission: a testifier often episodically remembers or imagines a scene while describing it, while a listener often imagines that scene as it’s described to her. I argue that getting clear on imagery’s psychological roles in testimonial belief transmission has implications for some fundamental issues in the epistemology of testimony. I first appeal to imagery cases to argue against a widespread “internalist” approach to the epistemology of testimony. I then appeal to the same sort (...) of case to argue for an alternative, externalist view. (shrink)

Amongst philosophers, there is ongoing debate about what successful event remembering requires. Causal theorists argue that it requires a causal connection to the past event. Simulation theorists argue, in contrast, that successful remembering requires only production by a reliable memory system. Both views must contend with the fact that people can remember past events they have experienced with varying degrees of accuracy. The debate between them thus concerns not only the account of successful remembering, but how each account explains the (...) various forms of memory error as well. Advancing the debate therefore must include exploration of the cognitive architecture implicated by each view and whether that architecture is capable of producing the range of event representations seen in human remembering. Our paper begins by exploring these architectures, framing casual theories as best suited to the storage of event instances and simulation theories as best suited to store schemas. While each approach has its advantages, neither can account for the full range of our event remembering abilities. We then propose a novel hybrid theory that combines both instance and schematic elements in the event memory. In addition, we provide an implementation of our theory in the context of a cognitive architecture. We also discuss an agent we developed using this system and its ability to remember events in the blocks world domain. (shrink)

Philosophers of memory have approached the relationship between memory and imagination from two very different perspectives. Advocates of the causal theory of memory, on the one hand, have motivated their preferred theory by appealing to the intuitive contrast between successfully remembering an event and merely imagining it. Advocates of the simulation theory, on the other hand, have motivated their preferred theory by appealing to empirical evidence for important similarities between remembering the past and imagining the future. Recently, causalists have argued (...) that simulationism is unable to accommodate the difference between successful remembering and forms of unsuccessful remembering or mere imagining such as confabulating. This paper argues that, while these arguments fail, simulationism, in its current form, is indeed unable to provide a fully adequate account of unsuccessful remembering. Rather than suggesting a return to causalism, the paper proposes a new form of simulationism, a virtue theory of memory modelled not on the process reliabilist epistemology that has so far served as the inspiration for the simulation theory but instead on virtue reliabilist epistemology, and shows that this new theory grounds a more adequate account of unsuccessful remembering.

Grief is a complex emotional experience or process, which is typically felt in response to the death of a loved one, most typically a family member, child, or partner. Yet the way in which grief manifests is much more complex than this. The things we grieve over are multiple and diverse. We may grieve for a former partner after the breakup of a relationship; parents sometimes report experiencing grief when their grown-up children leave the family home. We can also experience (...) grief for people we have never met. Indeed, it is not just persons that we may grieve for. People report feeling grief over the death of their pets, or about the destruction the natural environment. In all these cases one factor that seems to stand out is loss. Despite being about very different things, these various forms of grief all involve a loss of some sort. Yet there is a further aspect of grief, which, on the face of it, does not quite follow this pattern. Grief can also be experienced before a loss has occurred. Grief can be experienced while the person that one is grieving for is still living and before one has (fully) suffered the loss. This phenomenon is known as anticipatory grief. The experience of anticipatory grief is a complex phenomenon, which resists easy classification. Nonetheless, we suggest that mental time travel, our ability to mentally project ourselves into the personal past (episodic memory) and personal future (episodic prospection), is a key mechanism that underpins experiences of anticipatory grief. Anticipatory grief can still be understood in terms of loss, but it is a loss that is brought to mind through memory and imagination. (shrink)

We argue that the causal theory of memory and the simulation theory of memory are not as straightforwardly incompatible as they are usually taken to be. Following a brief review of the theories, we describe alternative normative and descriptive perspectives on memory, arguing that the causal theory aligns better with the normative perspective and the simulation theory with the descriptive perspective. Taking explanatory contextualism about perception as our starting point, we then develop a form of explanatory contextualism about memory, arguing (...) that, depending on the context in which we find ourselves, either the normative perspective or the descriptive perspective may be appropriate. It follows that, while the causal theory and the simulation theory cannot both be right with respect to a given perspective, and while it is necessary to choose one perspective or the other in a given context, there an important sense in which we need not choose between causalism and simulationism. We conclude by differentiating our position from and critiquing a related position developed by Craver (2020) and defending our position against objections. (shrink)

Martin and Deutscher’s causal theory of remembering holds that a memory trace serves as a necessary causal link between any genuine episode of remembering and the event it enables one to recall. In recent years, the causal theory has come under fire from researchers across philosophy and cognitive science, who argue that results from the scientific study of memory are incompatible with the kinds of memory traces that Martin and Deutscher hold essential to remembering. Of special note, these critics observe, (...) is that a single memory trace can be shaped by multiple past experiences. This appears to prevent traces from underwriting Martin and Deutscher’s distinction between remembering an event and merely forming an accurate representation of it. This paper accepts such criticisms of the standard causal theory and, through considering the phenomenon forgetting through repetition, raises several others. A substantially revised causal theory is then developed, compatible with the thesis that individual memory traces are shaped by multiple past experiences. The key strategy is to conceive of episodic remembering not as the simple retrieval and projection of a static memory trace, but as a complex quasi-inferential process that makes use of multiple forms of information and cues—“prop-like” memory traces included—in generating the experience known as episodic remembering. When remembering is understood as a multi-componential process, there are a variety of ways in which a representation of the past may be appropriately causally dependent upon a prior experience of the event remembered.

One goal of this paper is to argue that autobiographical memories are extended and distributed across embodied brains and environmental resources. This is important because such distributed memories play a constitutive role in our narrative identity. So, some of the building blocks of our narrative identity are not brain-bound but extended and distributed. Recognising the distributed nature of memory and narrative identity, invites us to find treatments and strategies focusing on the environment in which dementia patients are situated. A second (...) goal of this paper is to suggest various of such strategies, including lifelogging technologies such as SenseCams, life story books, multimedia biographies, memory boxes, ambient intelligence systems, and virtual reality applications. Such technologies allow dementia patients to remember their personal past in a way that wouldn’t be possible by merely relying on their biological memory, in that way aiding in preserving their narrative identity and positively contributing to their sense of well-being.

Richard Heersmink argues that self‐narratives are distributed across embodied organisms and their environment, given that their building blocks, autobiographical memories, are distributed. This argument faces two problems. First, it commits a fallacy of composition. Second, it relies on Marya Schechtman's narrative self‐constitution view, which is incompatible with the distributed cognition framework. To solve these problems, this article develops an alternative account of self‐narratives. On this account, we actively connect distributed autobiographical memories through distributed conversational and textual self‐narrative practices. This account (...) enhances our understanding of the memory–narrative nexus and has implications for philosophical conceptions of self. (shrink)

In recent years, philosophers of mind have explored the relationship between lived embodied experiences and self-narratives in bringing about a sense of self. This relationship has been vividly debated, with no consensus in the field. While some have argued that lived embodied experiences influence, but are not influenced by, self-narratives, others have maintained that lived embodied experiences and self-narratives influence each other across time. However, the very concept of ‘self-narrative’ and its scope of application has remained underspecified. The debate, I (...) will argue, can only be resolved if we arrive at a better theoretical understanding of self-narrative. Therefore, the purpose of this paper is to develop a conceptual account of the notion of ‘self-narrative’ and a descriptive account of its scope of application. It will then be shown how these accounts can pave the way towards resolving the debate on the experience-narrative nexus. (shrink)

I argue against mnemic reliabilism, an influential view that successful remembering must be produced by a reliable memory process. Drawing on empirical evidence from psychology and neuroscience, I refute mnemic reliabilism by demonstrating that: (1) patients with memory impairments (e.g., Alzheimer’s disease) can also successfully remember the past despite the unreliability of their corresponding memory processes; (2) some reliability-affecting factors (e.g., stress, divided attention, and insufficient encoding time) can render the memory processes of healthy individuals unreliable without preventing them from (...) occasionally resulting in successful remembering. Potential responses available for mnemic reliabilism are also evaluated. I show that those responses are susceptible to a challenge akin to the generality problem for process reliabilism. (shrink)

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.

This paper offers a modeling account of episodic representation. I argue that the episodic system constructsmental models: representations that preserve the spatiotemporal structure of represented domains. In prototypical cases, these domains are events: occurrences taken by subjects to have characteristic structures, dynamics and relatively determinate beginnings and ends. Due to their simplicity and manipulability, mental event models can be used in a variety of cognitive contexts: in remembering the personal past, but also in future-oriented and counterfactual imagination. As structural representations, (...) they allow surrogative reasoning, supporting inferences about their constituents which can be used in reasoning about the represented events. (shrink)

Debates about causation have dominated recent philosophy of memory. While causal theorists have argued that an appropriate causal connection to a past experience is necessary for remembering, their opponents have argued that this necessity condition needs to be relaxed. Recently, Jordi Fernández has attempted to provide such a relaxation. On his functionalist theory of remembering, a given state need not be caused by a past experience to qualify as a memory; it only has to realize the relevant functional role in (...) the subject’s mental economy. In this comment, I argue that Fernández’s theory doesn’t advance the debate about memory causation. I propose that this debate is best understood as being about the existence of systems, which support kinds of interactions that map onto the relations dictated by theories. Since Fernández’s functionalism tells us very little about this empirical question, the theoretical gains from endorsing it are minimal. (shrink)

Neste artigo apresentamos, de forma concisa e em português, alguns elementos-chave dos principais debates contemporâneos na filosofia da memória. Nosso principal objetivo é tornar essas discussões mais acessíveis aos leitores de língua portuguesa, fornecendo uma atualização importante para esforços anteriores (Sant’Anna & Michaelian, 2019a). Começamos introduzindo a noção de viagem no tempo mental, a qual estabelece a base empírica para a metodologia empregada em trabalhos recentes, antes de apresentar dois debates centrais. Primeiro, o debate entre causalistas e simulacionistas sobre a (...) teoria da lembrança filosoficamente correta (§2). Segundo, o debate entre continuístas e descontinuístas sobre a relação entre lembrança episódica e certas formas de imaginação (em particular, o pensamento episódico acerca do futuro) (§3). Na segunda parte do artigo, apresentamos e exploramos dois tópicos de discussão crescente: a natureza do sentimento de passado característico da memória episódica (§4) e questões de meta-nível relativas ao próprio caráter das controvérsias exploradas na primeira parte do artigo (§5).

Cats and dogs are the same kind of thing in being mammals, even if cats are not a kind of dog. In the same way, remembering and imagining might be the same kind of mental state, even if remembering is not a kind of imagining. This chapter explores whether episodic remembering, on the one hand, and future and counter-factual directed imagistic imagining, on the other, may be the same kind of mental state in being instances of the same cognitive attitude. (...) I outline a continuist position where all three involve the same judgment-like attitude and compare its advantages to a discontinuist alternative where remembering requires use of its own distinctive attitude. Reasons are given for favoring a version of the continuist position, though this chapter’s focus is on the metatheoretical questions of how to go about understanding remembering in terms of a content and attitude pair, and which considerations are relevant when deciding among competing content/attitude pairs.

Memory perspectives on past events allegedly take one of two shapes. In field memories, we recall episodes from a first-person point of view, while in observer memories, we look at a past scene from a third-person perspective. But this mere visuospatial dichotomy faces several practical and conceptual challenges. First, this binary distinction is not exhaustive. Second, this characterization insufficiently accounts for the phenomenology of observer memories. Third, the focus on the visual aspect of memory perspective neglects emotional, agential, and self-related (...) social aspects. Fourth, the focus on the time of recall neglects the fact that visual, emotional, agential, and social aspects of perspective can also be dissociated in the original experience. In this chapter, we move away from the standard visual dichotomy. Instead, we propose that memory perspective is better understood along four lines: visual, agential, emotional, and social. Drawing on empirical research, we argue that these dimensions predict a disposition to recall a past event based on the present situation of the memorizer. This account supports seeing episodic memory as a natural kind, supported by scenario construction mechanisms and minimal memory traces. By remapping the classic distinction between field and observer perspectives along four dimensions, our proposal provides explanatory advantages and secures practical gains by enabling testable hypotheses.

In this paper, I argue that causal theories of memory are typically committed to two independent, non-mutually entailing theses. The first thesis pertains to the necessity of appropriate causation in memory, specifying a condition token memories need to satisfy. The second pertains to the explanation of memory reliability in causal terms and it concerns memory as a type of mental state. Post-causal theories of memory can reject only the first (weak post-causalism) or both (strong post-causalism) theses. Upon this backdrop, I (...) examine Werning’s (2020) causalist argument from probabilistic correlation. I argue that it doesn’t establish the necessity of appropriate causation and thus it can only target strong post-causalist theories. I end up by presenting some general considerations, suggesting that memories may not always be causally linked to past experiences. (shrink)

Is an appropriate causal connection to the past experience it represents a necessary condition for a mental state to qualify as an episodic memory? For some years this issue has been the subject of an intense debate between the causalist theory of episodic memory (CTM) and the simulationist theory of episodic memory (STM). This paper aims at exploring the prospects for an embodied approach to episodic memory and assessing the potential case for causalism that could be founded on it. In (...) a critical section, it argues that the empirical data to which STM appeals are both incomplete and inconclusive, and on closer examination even provide support for a proceduralist version of CTM. In a constructive section, it elaborates on the notion of a necessary causal connection in terms of particular procedural patterns acquired at encoding and operative at retrieval, grounding this move on recent empirical data about eye movements in mnemonic mental imagery.

Traditionally, philosophers consider the question of whether episodic memory and imagination belong to the same kind (the (dis)continuism problem) as ultimately depending on the causality question - i.e., whether remembering requires a causal connection to the past event. In this framework, if memory is a simulation process (as claimed by simulationism) and does not require a causal connection, then it is sufficiently similar to imagination and, thus, continuism follows. On the other hand, if a causal connection is necessary for memory (...) (as defended by causalism), then there are fundamental differences between memory and imagination and, thus, discontinuism follows. In contrast with this framework, I will argue that such entanglement is due to a failure of clearly delineating issues of explanation and classification. By distinguishing these matters more explicitly, I conclude that continuism is the better alternative for classification purposes, while maintaining that causalism is still necessary for explaining how memory works.
