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)

Conscious recollection, of the kind characterised by sensory mental imagery, is often thought to involve ‘episodically’ recalling experienced events in one’s personal past. One might wonder whether this overlooks distinctive ways in which we sometimes recall ordinary, persisting objects. Of course, one can recall an object by remembering an event in which one encountered it. But are there acts of recall which are distinctively objectual in that they are not about objects in this mediated way (i.e., by way of being (...) about events in which they featured)? This question has broad implications, not least for understanding the nature and role of imagery in remembering, the requirements of memory-based singular thought about objects, and the sense in which remembering involves ‘mental time travel’ through which one ‘relives’ past events. In this paper, I argue that we sometimes do recall objects from our past without remembering events in which they featured. The positive view of such cases I go on to propose draws on a wide body of empirical work in its support and accommodates a more nuanced picture of the role of imagery in remembering. In a slogan: remembering might essentially involve a kind of ‘re-experiencing’, but it need not involve ‘reliving’. (shrink)

Recently, a view I refer to as “hypothetical continuism” has garnered some favour among philosophers, based largely on empirical research showing substantial neurocognitive overlaps between episodic memory and imagination. According to this view, episodically remembering past events is the same kind of cognitive process as sensorily imagining future and counterfactual events. In this paper, I first argue that hypothetical continuism is false, on the basis of substantive epistemic asymmetries between episodic memory and the relevant kinds of imagination. However, I then (...) propose and defend an alternative form of continuism, according to which episodic memory is continuous with a capacity I call “actuality-oriented imagination.” Because of the deep epistemic affinities between episodic memory and actuality-oriented imagination, it makes sense to think of them as cognitive processes of the same kind.

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.

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)

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.
