In the philosophy of memory, singularism is the view that episodic memories are singular mental states about unique personally experienced past events. In this paper, I present an empirical challenge to singularism. I examine three distinct lines of evidence from the psychology of memory, concerning general event memories, the transformation of memory traces and the minimized role temporal information plays in major psychological theories of episodic memory. I argue that singularist views will have a hard time accommodating this evidence, facing (...) a problem of transitional gradation. I then look at some potential consequences for the larger debate, highlighting the way in which singularism has featured in three important recent arguments in the philosophy of memory. (shrink)

Re-encountering certain kinds of artworks in the present (re-listening to music, re- reading novels) can often occasion a kind of recollection akin to episodic recollection, but which may be better cast as ‘phasic’, at least insofar as one can be said to remember ‘what it was like’ to be oneself at some earlier stage or phase in one’s personal history. The kinds of works that prompt such recollection, I call ‘still lives’ - they are limited wholes whose formal properties are (...) stable over time. In the first part of the paper, I spell out a way of making sense of the peculiar power that certain artworks have to occasion such recollection – it is, as I explain, a power or ductus that derives from the form of the artwork, though possession of such a power is not limited to art. I then detail three dimensions along which episodic recollection and phasic recollection as occasioned by re-encountering ‘still lives’ differ: metaphysical, phenomenological, and descriptive. In the second half, I explore a challenge for my account of phasic recollection, which in turn helps make more vivid my proposal as well as the spectral analogy at the heart of it: Just as one can see regions behind one by looking in the direction of a mirror located in the same space in which one is, sometimes by re-encountering certain kinds of artworks now, past intervals or phases ‘behind one’ can be ‘made present’ in a way that the paper aims to make plain. I also explain to what extent phasic recollection might be understood as a form of mental time travel, and what the attendant phenomenology of ‘transportation’ involves. (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.

The construct “remembering” is equivocal between an epistemic sense, denoting a distinctive ground for knowledge, and empirical sense, denoting the typical behavior of a neurocognitive mechanism. Because the same kind of equivocation arises for other psychologistic terms, the effort to spot and remedy the confusion in the case of remembering might prove generally instructive. The failure to allow these two senses of remembering equal play in their respective domains leads, I argue, to unnecessary confusion about memory externalism, the possibility of (...) episodic memory in non-human species, and the thesis of memory continuism. By distinguishing these equivocal senses of remembering, we thus gain leverage on understanding how the distinctive epistemic norms that define many of our psychologic terms are more plausibly related to the capacities studied by empirical science, given that neither identity nor elimination are possible.

Mental time travel is defined as projecting the self into the past and the future. Despite growing evidence of the similarities of remembering past and imagining future events, dominant theories conceive of these as distinct capacities. I propose that memory and imagination are fundamentally the same process – constructive episodic simulation – and demonstrate that the ‘simulation system’ meets the three criteria of a neurocognitive system. Irrespective of whether one is remembering or imagining, the simulation system: acts on the same (...) information, drawing on elements of experience ranging from fine-grained perceptual details to coarser-grained conceptual information and schemas about the world; is governed by the same rules of operation, including associative processes that facilitate construction of a schematic scaffold, the event representation itself, and the dynamic interplay between the two ; and is subserved by the same brain system. I also propose that by forming associations between schemas, the simulation system constructs multi-dimensional cognitive spaces, within which any given simulation is mapped by the hippocampus. Finally, I suggest that simulation is a general capacity that underpins other domains of cognition, such as the perception of ongoing experience. This proposal has some important implications for the construct of ‘MTT’, suggesting that ‘time’ and ‘travel’ may not be defining, or even essential, features. Rather, it is the ‘mental’ rendering of experience that is the most fundamental function of this domain-general simulation system enabling humans to re-experience the past, pre-experience the future, and also comprehend the complexities of the present.

Bringing research on collective memory together with research on episodic future thought, Szpunar and Szpunar :376–389, 2016) have recently developed the concept of collective future thought. Individual memory and individual future thought are increasingly seen as two forms of individual mental time travel, and it is natural to see collective memory and collective future thought as forms of collective mental time travel. But how seriously should the notion of collective mental time travel be taken? This article argues that, while collective (...) mental time travel is disanalogous in important respects to individual mental time travel, the concept of collective mental time travel nevertheless provides a useful means of organizing existing findings, while also suggesting promising directions for future research.

It is natural to think of remembering in terms of causation: I can recall a recent dinner with a friend because I experienced that dinner. Some fifty years ago, Martin and Deutscher (1966) turned this basic thought into a full-fledged theory of memory, a theory that came to dominate the landscape in the philosophy of memory. Remembering, Martin and Deutscher argue, requires the existence of a specific sort of causal connection between the rememberer's original experience of an event and his (...) later representation of that event: a causal connection sustained by a memory trace. In recent years, it has become apparent that this reference to memory traces may be out of step with memory science. Contemporary proponents of the causal theory are thus confronted with the question: is it possible to develop an empirically adequate version of the theory, or is it time to move beyond it? This chapter traces the recent history of the causal theory, showing how increased awareness of the theory’s problems has led to the development of modified version of the causal theory and ultimately to the emergence of postcausal theories.

Remembering is one of the most characteristic and most puzzling of human activities. Personal memory, in particular - the ability mentally to travel back into the past, as leading psychologist Endel Tulving puts it - often has intense emotional or moral significance: it is perhaps the most striking manifestation of the peculiar way human beings are embedded in time, and of our limited but genuine freedom from our present environment and our immediate needs. Memory has been significant in the history (...) of philosophy as much in relation to ethics and to epistemology as in theories of psyche, mind, and self. (shrink)
