The Morris water maze has been put forward in the philosophy of neuroscience as an example of an experimental arrangement that may be used to delineate the cognitive faculty of spatial memory (e.g., Craver and Darden, Theory and method in the neurosciences, University of Pittsburgh Press, Pittsburgh, 2001; Craver, Explaining the brain: Mechanisms and the mosaic unity of neuroscience, Oxford University Press, Oxford, 2007). However, in the experimental and review literature on the water maze throughout the history (...) of its use, we encounter numerous responses to the question of “what” phenomenon it circumscribes ranging from cognitive functions (e.g., “spatial learning”, “spatial navigation”), to representational changes (e.g., “cognitive map formation”) to terms that appear to refer exclusively to observable changes in behavior (e.g., “water maze performance”). To date philosophical analyses of the water maze have not been directed at sorting out what phenomenon the device delineates nor the sources of the different answers to the question of what. I undertake both of these tasks in this paper. I begin with an analysis of Morris’s first published research study using the water maze and demonstrate that he emerged from it with an experimental learning paradigm that at best circumscribed a discrete set of observable changes in behavior. However, it delineated neither a discrete set of representational changes nor a discrete cognitive function. I cite this in combination with a reductionist-oriented research agenda in cellular and molecular neurobiology dating back to the 1980s as two sources of the lack of consistency across the history of the experimental and review literature as to what is under study in the water maze.

William Lane Craig modified Bertrand Russell’s Tristram Shandy example in order to derive an absurdity that would demonstrate the finitude of the past. Although his initial attempt at such an argument faltered, further developments in the literature suggested that such an absurdity was indeed in the offing provided that a couple extra statements were also shown to be true. This article traces the development of a particular line of argument that arose from Craig’s Tristram Shandy example before advancing an argument (...) of its own that attempts to fill in the relevant gaps so as to yield a new argument for the finitude of the past.

Meta-ethical attempts to define concepts such as 'goodness', ‘right and wrong’, ‘ought’ and ‘ought not’, have proved largely futile, even over-ambitious. Morality, it is argued, should therefore be directed primarily at the reduction of suffering, principally because the latter is more easily recognisable and accords with an objective view and requirements of the human condition. All traditional and contemporary perspectives are without suitable criteria for evaluating moral dilemmas and without such guidance we face the potent threat of sliding to a (...) destructive moral nihilism. This book presents a possible set of defining characteristics for the foundation of future moral evaluations and engagements, taking into consideration that the historically maligned female gender may be better disposed to ethical leadership.

William Lane Craig has revived interest in the medieval kalām argument to the point where it is now one of the most discussed arguments for God’s existence in the secondary literature. Still, the reception of Craig’s argument among philosophers of religion has been mostly critical. In the interest of developing an argument that more philosophers of religion would be inclined to support, I will lay the philosophical groundwork for a new kalām cosmological argument that, in contrast with Craig’s argument, does (...) not adopt such controversial positions as the dynamic theory of time and the metaphysical impossibility of an actual infinite.

I describe two traditions of philosophical accounts of evidence: one characterizes the notion in terms of signs of success, the other characterizes the notion in terms of conditions of success. The best examples of the former rely on the probability calculus, and have the virtues of generality and theoretical simplicity. The best examples of the latter describe the features of evidence which scientists appeal to in practice, which include general features of methods, such as quality and relevance, and general features (...) of evidence, such as patterns in data, concordance with other evidence, and believability of the evidence. Two infamous episodes from biomedical research help to illustrate these features. Philosophical characterization of these latter features—conditions of success—has the virtue of potential relevance to, and descriptive accuracy of, practices of experimental scientists. (shrink)

In this paper it is analyzed from the informational perspective the relation between mind and body, an ancient philosophic issue defined as a problem, which still did not receive up to date an adequate solution. By introducing/using the concept of information, it is shown that this concept includes two facets, one of them referring to the common communications and another one referring to a hidden/structuring matter-related information, effectively acting in the human body and in the living systems, which determines the (...) dynamic inter-change of information between specific structures of the organism by electric/electronic/chemical agents and genetic/epigenetic processes. It is shown that the maintenance of body, permanently and obligatory depending on the external matter (foods, air, water) resources, needed to provide both the structuring/restructuring basic material and energy, determines the necessary existence of an info-managing system, administrating the internal mechano-chemical/physical processes. As a natural consequence, such a system should organize and assure own survival by an effective informational operability to detect the external food resources, to select the appropriate interest information and to decide as a function of circumstances. One important component in such an informational system is memory, allowing to dispose of the reference informational data for analysis/comparison and the selection between good and bad binary possible decisions. The memory receives and stores therefore signals from external reality and from the body itself, referring to the emotional reaction, digestion status, creation, and inherited predilections, within specific info-neural communication circuits between the brain and body execution/sensitive organs, the human body appearing as an integrated info-matter self-managed dynamic system. The specific body components memorize information with different degrees of info-integration: short/long-term integration, emotive/action reaction, info-abilities, culminating with the integration in the chromosomal structures by epigenetic processes. The new acquired information is transgenerationally transmissible, and is manifested as new traits, showing the adaptation capability of the human and close relation between mind and body. Analyzing the results of such a mind-body informational model in comparison with the earlier assumed/proposed/asserted archaic, Greek and Occidental philosophies, which represent only partial aspects of this relation, it is shown that this informational model, elaborated in terms of information on the basis of scientific reasons and arguments, constitutes a general, realist, and coherent model of the mind-body relation, able to integrate and/or explain most of the others.

Let us begin with Lethe, a river in Hades whose waters caused forgetfulness to dead souls who drank from it. The daughter of Eris, Lethe was the sister of Thanatos , and with Zeus she bore the Graces/Charites. According to some myths, she was the mother of Dionysus. She was the goddess of oblivion and the river with the same name. When someone died and went to Hades, they had to drink from her water so they would forget their (...) previous existence on earth. Once they had drunk from the waters of Lethe, they were left with nothing to reminisce about for eternity. If ever anybody was allowed back to life, again they had to drink from the river so they would not remember the afterlife. One of memory’s earliest myths proclaims that at the dawn of philosophy, at the oracle of Lebadeia, a descent into Hades required that the questor be first taken to Lethe, the spring of forgetfulness, and then to Mnemosyne, the mother of the Muses, the second spring, the spring of remembrance. Jean Pierre Vernant recounts the legend thus: Before venturing into the mouth of hell, the questor, who had already undergone rites of purification, was taken to two springs named respectively Lethe and Mnemosoune. He drank from the first and immediately forgot everything to do with his human life and, like a dead man, he entered the realm of Night. The water of the second spring was to enable him to remember all that he had seen and heard in the other world. When he returned he was no longer restricted to knowledge of the present moment: contact with the beyond had revealed both past and future to him. 2 Two questions that immediately come to mind are concerned with the anteriority of forgetting in relation to memory. Why was the initiate taken first to Lethe? What was the motivation behind this unusual ritual in the cavern of Trophonius in Boetia that demands forgetfulness as the first step? Secondly, why is the power of memory, which enables him to remember what “he had seen and heard in the other world,” constituted as the second step – though unmistakably a step, an unmistakable step – toward knowledge? The dip in the Lethe cleanses the initiate from the distracting and unmitigated sorrows of the past like a clean slate. It is well known that for the ancient Greeks, knowledge, a source of immortality, derived from memory. One could ask, is the knowledge that memory brings to us the knowledge that memory is the first presence of what was before it, namely forgetting? (shrink)

The art of Simon Finn has always had a markedly temporal dynamic. Vast structures built and annihilated again and again across different media, their fragmentation across space and time simultaneously methodical and darkly chaotic. Roiling waters and eldritch surfaces held captive in their unrest. Finn’s works render cycles of construction and disintegration, of stasis and motion, in ways that shed light upon the underlying structures of our experience of time while shattering simplistic notions of linearity. This is nowhere more apparent (...) than in Instability, through which Finn allows us to explore the intertwining of personal and historical time, ancestral memory and radical futurity, artefactual form and temporal function.

In this paper I argue in favor of the compatibility of semantic externalism with privileged self-knowledge by showing that an argument for incompatibilism from switching scenarios fails. Given the inclusion theory of self-knowledge, the hypothesis according to which I am having twater thoughts while thinking that I have water thoughts simply isn't a (entertainable) possibility. When I am on Earth thinking earthian concepts, I cannot believe that I am thinking that twater is wet for I don't have the concept (...) of twater available; so this concept cannot figure in any of my mental states. Analogously, when I am on Twin Earth, I cannot mistakenly believe that I am entertaining water thoughts. No matter how often I am switched between Earth and Twin Earth, I will never erroneously think that I am having water thoughts while in fact I am having twater thoughts and vice versa. Privileged self-knowledge is therefore immune to skeptical arguments from switching and twinning scenarios. (shrink)

Clinical evidence has shown that physical exercise during pregnancy may alter brain devel- opment and improve cognitive function of offspring. However, the mechanisms through which maternal exercise might promote such effects are not well understood. The present study examined levels of brain-derived neurotrophic factor (BDNF) and absolute cell num- bers in the hippocampal formation and cerebral cortex of rat pups born from mothers exer- cised during pregnancy. Additionally, we evaluated the cognitive abilities of adult offspring in different behavioral paradigms (exploratory (...) activity and habituation in open field tests, spatial memory in a water maze test, and aversive memory in a step-down inhibitory avoid- ance task). Results showed that maternal exercise during pregnancy increased BDNF lev- els and absolute numbers of neuronal and non-neuronal cells in the hippocampal formation of offspring. No differences in BDNF levels or cell numbers were detected in the cerebral cortex. It was also observed that offspring from exercised mothers exhibited better cognitive performance in nonassociative (habituation) and associative (spatial learning) mnemonic tasks than did offspring from sedentary mothers. Our findings indicate that maternal exer- cise during pregnancy enhances offspring cognitive function (habituation behavior and spa- tial learning) and increases BDNF levels and cell numbers in the hippocampal formation of offspring.

This chapter argues that the space of the thermal pool is central to Tarkovsky’s exploration of the mystery of sacrifice and the pain of exile in Nostalghia. Spatially, the geometry and textures of the pool are echoed throughout the film’s interiors, in hotel corridors and cathedrals. I propose that we can see Tarkovsky’s aesthetic in Nostalgia as one of overflow. The water that initially fills the pool overflows into nearly every scene, as interiors of houses are flooded in dream-like (...) visions, and the echoing sound of dripping water is omnipresent. Thematically, the film explores the way in which past and present, memory and dream, and the spaces of home and exile flow into each other, using techniques of superimposition. I argue that such overflowing, in both theme and aesthetic, can be productively read in conjunction with Henri Bergson’s theories of duration, in which variegated temporal rhythms continually bleed into each other. Nostalgia’s pool forms a space of becoming, where place and identity is continually in flux. (shrink)

Easter is the most important solemnity (just before Christmas) of the Church. It is the first of the five cardinal feasts of the Catholic liturgical year. Easter commemorates the resurrection of Jesus Christ laid down by the Bible, the third day after his passion. The solemnity begins on Easter Sunday, which for Catholics mark the end of fasting of Lent, and lasts for eight days (Easter week, or week or radiant, or week of eight Sundays). Many customs dating back to (...) ancient times designed to accommodate the return of spring attached themselves to Easter. The egg is the symbol of germination occurs in early spring. Similarly, the hare is an ancient symbol which has always represented fertility. The custom of the Easter egg was found among Coptic Christians from the late fifth century, it is perhaps in memory of ardent eggs (ova ignita) with which the martyrs were tortured or red egg laid by an imperial hen the day of the birth of Alexander Severus in 208 BC. The tradition of offering eggs in spring dates back to antiquity: the Persians, the Egyptians offered, as a lucky, decorated hen eggs as renewal sign. The rabbit once symbolizing fertility and renewal (like spring), it was in Upper Germany where was born the tradition (Osterhase) before it spreads in the Germanic countries. Subsequently, this tradition is exported to the United States by German immigrants in the eighteenth century.

Given the close relatedness of local issues, water scarcity, and sustainability, this research sought to investigate the factors affecting residents’ willingness to reuse direct and indirect potable water in the arid region. Utilizing the Bayesian Mindsponge Framework (BMF), an analysis was undertaken with a sample of 1,831 water consumers in the City of Albuquerque, the most populous city in New Mexico, United States. The primary analysis revealed positive associations between local concerns about drought or water scarcity (...) and population growth with residents' willingness to reuse direct and indirect potable water. Conversely, concerns about water quality and water bills were found to be negatively associated with the willingness to utilize directly and indirectly recycled water for drinking. In light of these findings, the study explores the potential of fostering an eco-surplus culture by cultivating a sense of environmental responsibility and acknowledging the relationship between local issues and environmental conditions. Simultaneously, the study proposes collaboration between the government and residents to promote water reuse programs to conserve water resources effectively. (shrink)

In a recent study by Cai et al. about water shortages in Beijing-Tianjin-Hebei urban areas, virtual water has become the central concept of the groundwater security strategy by suggesting increasing imports of water-intensive agricultural products instead of utilizing the depleted groundwater resources for production. However, despite reviewing the content, we could not see how the authors discussed the households’ economic and financial issues from both production and consumption perspectives.

The Twin Earth thought experiment invites us to consider a liquid that has all of the superficial properties associated with water (clear, potable, etc.) but has entirely different deeper causal properties (composed of “XYZ” rather than of H2O). Although this thought experiment was originally introduced to illuminate questions in the theory of reference, it has also played a crucial role in empirically informed debates within the philosophy of psychology about people’s ordinary natural kind concepts. Those debates have sought to (...) accommodate an apparent fact about ordinary people’s judgments: Intuitively, the Twin Earth liquid is not water. We present results from four experiments showing that people do not, in fact, have this intuition. Instead, people tend to have the intuition that there is a sense in which the liquid is not water but also a sense in which it is water. We explore the implications of this finding for debates about theories of natural kind concepts, arguing that it supports views positing two distinct criteria for membership in natural kind categories – one based on deeper causal properties, the other based on superficial, observable properties.

A natural view of testimony holds that a source's statements provide one with evidence about what the source believes, which in turn provides one with evidence about what is true. But some theorists have gone further and developed a broadly analogous view of memory. According to this view, which this essay calls the “diary model,” one's memory ordinarily serves as a means for one's present self to gain evidence about one's past judgments, and in turn about the truth. (...) This essay rejects the diary model's analogy between memory and testimony from one's former self, arguing first that memory and a diary differ with respect to their psychological roles, and second that this psychological difference underwrites important downstream epistemic differences. The resulting view stands opposed to prominent discussions of memory and testimony, which either, like the diary model, treat memory by analogy to what we naively wish to say about testimony, or which instead attempt to extend to testimony the epistemically preservative role of memory.

This paper will focus on a famous nineteenth century debate over the physiology of perception between Ewald Hering and Hermann von Helmholtz. This debate is often explained as a contest between empiricism (Helmholtz) and nativism (Hering) about perception. I will argue that this is only part of the picture. Hering was a pioneer of Lamarckian explanations, arguing for an early version of the biogenetic law. Hering explains physical processes, including perception, in terms of ‘organic memory’ that is supported by (...) ‘vital forces’ located throughout the body. Helmholtz, on the other hand, argues that vital forces are in direct conflict with the results he and others proved in the 1840s and 50s on the conservation of force. The battleground of the debate was the interpretation of Johannes Müller’s ‘law of specific nerve energies’, which Hering interpreted in terms of vital forces, and Helmholtz interpreted using a naturalized neo-Kantian approach. In the end, the debate revealed deep fissures in nineteenth century accounts of scientific explanation, as well as in the conception of how physiology, psychology, physics, and philosophy are related.

Optogenetics is an invasive neuromodulation technology involving the use of light to control the activity of individual neurons. Even though optogenetics is a relatively new neuromodulation tool whose various implications have not yet been scrutinized, it has already been approved for its first clinical trials in humans. As optogenetics is being intensively investigated in animal models with the aim of developing novel brain stimulation treatments for various neurological and psychiatric disorders, it appears crucial to consider both the opportunities and dangers (...) such therapies may offer. In this review, we focus on the memory-modifying potential of optogenetics, investigating what it is capable of and how it differs from other memory modification technologies. We then outline the safety challenges that need to be addressed before optogenetics can be used in humans. Finally, we re-examine crucial neuroethical concerns expressed in regard to other MMTs in the light of optogenetics and address those that appear to be unique to the memory-modifying potential of optogenetic technology.

In this paper, we evaluate the pragmatic turn towards embodied, enactive thinking in cognitive science, in the context of recent empirical research on the memory palace technique. The memory palace is a powerful method for remembering yet it faces two problems. First, cognitive scientists are currently unable to clarify its efficacy. Second, the technique faces significant practical challenges to its users. Virtual reality devices are sometimes presented as a way to solve these practical challenges, but currently fall short (...) of delivering on that promise. We address both issues in this paper. First, we argue that an embodied, enactive approach to memory can better help us understand the effectiveness of the memory palace. Second, we present design recommendations for a virtual memory palace. Our theoretical proposal and design recommendations contribute to solving both problems and provide reasons for preferring an embodied, enactive account over an information-processing treatment of the memory palace.

One distinct interest in self-knowledge concerns whether one can know about one’s own mental states and processes, how much, and by what methods. One broad distinction is between accounts that centrally claim that we look inward for self-knowledge (introspective methods) and those that claim that we look outward for self-knowledge (transparency methods). It is here argued that neither method is sufficient, and that we see this as soon as we move beyond questions about knowledge of one’s beliefs, focusing instead on (...) how one distinguishes, for oneself, one’s veridical visual memories from mere (non-veridical) visual images. Given robust psychological and phenomenal similarities between episodic memories and mere imagery, the following is a genuine question that one might pose to oneself: “Do I actually remember that happening, or am I just imagining it?” After critical analysis of the transparency method (advocated by Byrne 2010, following Evans 1982) to this latter epistemological question, a brief sketch is offered of a more holistic and inferential method for acquisition of broader self-knowledge (broadly following the interpretive-sensory access account of Carruthers 2011). In a slogan, knowing more of the mind requires using more of the mind. (shrink)

Water quality assessment is critical for environmental sustainability and public health.

Water is the source of life for our planet, guided the ancient civilizations, and formed its current footprint on the earth. Water has always been a crucial element of our biological survival; consequently, humankind has permanently settled around it while carrying the responsibility of protecting it.

Despite the adverse effects of the Covid-19 pandemic on education, international researchers contribute to the studio in a beneficial and diversified manner with the effective use of online tools. As a result of the literature review and the online, multidisciplinary education, and research-based design requirements, a new studio method was developed. Water-based case studies worldwide produced enriched outputs. While creating new discussion environments, the diversified outcomes of the studio "Around Water" contributed to the creation of cumulative studio knowledge. (shrink)

Memory of past episodes provides a sense of personal identity — the sense that I am the same person as someone in the past. We present a neurological case study of a patient who has accurate memories of scenes from his past, but for whom the memories lack the sense of mineness. On the basis of this case study, we propose that the sense of identity derives from two components, one delivering the content of the memory and the (...) other generating the sense of mineness. We argue that this new model of the sense of identity has implications for debates about quasi-memory. In addition, articulating the components of the sense of identity promises to bear on the extent to which this sense of identity provides evidence of personal identity. (shrink)

The clash between Galileo and the Catholic Inquisition has been discussed, studied, and written about for many decades. The scientific, theological, political, and social implications have all been carefully analysed and appreciated in all their interpretative fruitfulness. The relatively recent trend in this kind of scholarship however seems to have underestimated the fact that Galileo in this debate, as in his earlier debates, showed a particular style marked by overconfidence. If we keep in mind the Lakatosian account of scientific development, (...) it is of course perfectly understandable that scientists at times stick to their convictions by producing auxiliary hypotheses as buffers against contrary evidence. And elements of this are detectable in the arguments of both Galileo and his opponents. But one still needs to ask: To what extent did Galileo depend on auxiliary hypotheses? How insecure did they render his position? And how ad hoc were they? These are important questions because Galileo’s particular way of dealing with auxiliary hypotheses can throw light on the broader question of when and how auxiliary hypotheses are needed within scientific practice in general. It can even indicate some way of conceiving degrees of ad hocness. In this paper, I explore this issue by comparing two important debates in which Galileo was involved: one about the nature of water and buoyancy, the other about cosmology. I revisit not only the scientific content of these debates but also the cultural context in which they took place, especially their dependence on patronage and their theological repercussions. The results indicate that scholarship on Galileo can still be useful in clarifying currently relevant aspects of scientific practice, and is thus still far from its expiry date. (shrink)

This paper explores the implications of the psychology of constructive memory for philosophical theories of the metaphysics of memory and for a central question in the epistemology of memory. I first develop a general interpretation of the psychology of constructive memory. I then argue, on the basis of this interpretation, for an updated version of Martin and Deutscher's influential causal theory of memory. I conclude by sketching the implications of this updated theory for the question (...) of memory 's status as a generative epistemic source. (shrink)

Through the philosophies of Bergson and Deleuze, my paper explores a different theory of time. I reconstitute Deleuze’s paradoxes of the past in Difference and Repetition and Bergsonism to reveal a theory of time in which the relation between past and present is one of coexistence rather than succession. The theory of memory implied here is a non-representational one. To elaborate this theory, I ask: what is the role of the “virtual image” in Bergson’s Matter and Memory? Far (...) from representing the simple afterimage of a present perception, the “virtual image” carries multiple senses. Contracting the immediate past for the present, or expanding virtually to hold the whole of memory (and even the whole of the universe), the virtual image can form a bridge between the present and the non-representational past. This non-representational account of memory sheds light not only on the structure of time for Bergson, but also on his concepts of pure memory and virtuality. The rereading of memory also opens the way for Bergsonian intuition to play an intersubjective role; intuition becomes a means for navigating the resonances and dissonances that can be felt between different rhythms of becoming or planes of memory, which constitute different subjects.

Memory seems intuitively to consist in the preservation of some proposition (in the case of semantic memory) or sensory image (in the case of episodic memory). However, this intuition faces fatal difficulties. Semantic memory has to be updated to reflect the passage of time: it is not just preservation. And episodic memory can occur in a format (the observer perspective) in which the remembered image is different from the original sensory image. These difficulties indicate that (...) memory cannot be preserved content. It is proposed that what is preserved in memory isan underlying "trace", and that in every act of remembering, memorial content is reconstructed from the preserved trace. (shrink)

I argue that our current practice of ascribing the term “ memory ” to mental states and processes lacks epistemic warrant. Memory, according to the “received view”, is any state or process that results from the sequential stages of encoding, storage and retrieval. By these criteria, memory, or its footprint, can be seen in virtually every mental state we are capable of having. This, I argue, stretches the term to the breaking point. I draw on phenomenological, historical (...) and conceptual considerations to make the case that an act of memory entails a direct, non-inferential feeling of re-acquaintance with one’s past. It does so by linking content retrieved from storage with autonoetic awareness during retrieval. On this view, memory is not the content of experience, but the manner in which that content is experienced. I discuss some theoretical and practical implications and advantages of adopting this more nuanced view of memory. -/-. (shrink)

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.

It has long been known that memory need not be a literal reproduction of the past but may be a constructive process. To say that memory is a constructive process is to say that the encoded content may differ from the retrieved content. At the same time, memory is bound by the authenticity constraint which states that the memory content must be true to the subject's original perception of reality. This paper addresses the question of how (...) the constructive nature of visual memory can be reconciled with the authenticity constraint. In what respect and to what extent may the content of a visual memory differ from the original perceptual state while still adequately reflecting the subject's original perception? (shrink)

In this chapter, I present and explore various arguments for skepticism that are related to memory. My focus will be on the aspects of the arguments that are unique to memory, which are not shared, for example, by the more often explored skeptical arguments related to perception. -/- Here are some interesting upshots. First, a particular problem for justifiably concluding that one's memory is reliable is that any reasoning in favor of this conclusion will either result in (...) epistemically circularity or not be sufficient to justify the conclusion. Second, since many beliefs stored in memory do not appear to be based on evidence, it might also appear to follow that they are not justified. Third, although many stored memory beliefs are not based on stored memory experiences in the same way that perceptual beliefs are based on perceptual experiences, skeptical scenarios loom just as problematically for memory beliefs as they do for perceptual beliefs.

The expression “repressed memory” was introduced over 100 years ago as a theoretical term purportedly referring to an unobservable psychological entity postulated by Freud’s seduction theory. That theory, however, and its hypothesized cognitive architecture, have been thoroughly debunked—yet the term “repressed memory” seems to remain. In this paper I offer a philosophical evaluation of the meaning of this theoretical term as well as an argument to question its scientific status by comparing it to other cases of theoretical terms (...) that have either survived scientific change—such as “atom” or “gene”—or that have perished, such as “black bile”. Ultimately, I argue that “repressed memory” is more like “black bile” than “atom” or “gene” and, thus, recommend its demotion from our scientific vocabulary. (shrink)

Earth and every living organism on this planet require water for survival and without water there would be no life. Drinking water should be clean that means it should be free from micro-organisms, free from harmful chemical and other pollutants. Consuming unsafe drinking water may lead to several water borne diseases, and other long term and chronic health problems. Water conservation encompasses the policies, strategies and activities to manage fresh water as a sustainable (...) resource to protect the water environment and to meet current and future human demand. Water conservation in simple words, is an effort to save water and ultimately save the planet. Water conservation is needed to protect the ecosystem and to restore its fast deterioration and to overcome the threats of environmental degradation, to meet the unavoidable emergency of shortage for drinking and domestic water in near future.

Remembering seems, to philosophers and scientists, one of the most mystifying of human activities. Yet natural language users have no problem understanding what is meant by ‘memory’. Memory is simply the ability to recall personally experienced events and certain kinds of information such as facts, names, or faces; or how to perform certain actions, like riding a bike or playing chess. It is on this basis that people sometimes make claims about themselves or others having a good or (...) bad memory, especially for things like names, numbers, or faces. Why then is memory such a mystery? Because, firstly, of its diversity: memory enables us to perform a plethora of different tasks, including the continuous interpretation of every moment of consciousness. Secondly, different forms of memory have different standards of accuracy, and often dramatically different criteria for success. (shrink)

Memory skepticism denies our memory beliefs could have any notable epistemic good. One route to memory skepticism is to challenge memory’s epistemic trustworthiness, that is, its functioning in a way necessary for it to provide epistemic justification. In this paper we develop and respond to this challenge. It could threaten memory in such a way that we altogether lack doxastic attitudes. If it threatens memory in this way, then the challenge is importantly self-defeating. If (...) it does not threaten memory in this way, then the challenge leaves a foundation for an inference to the best explanation response, one we articulate and support. (shrink)

Episodic memory is sometimes described as mental time travel. This suggests three ideas: that episodic memory offers us access to the past that is quasi-experiential, that it is a source of knowledge of the past, and that it is, at root, passive. I offer an account of episodic memory that rejects all three ideas. The account claims that remembering is a matter of representing the past to oneself, in a way suitably responsive to how one experienced the (...) remembered episode to be. I argue that episodic memory is active, in the way this view suggests. I clarify the idea that it is, as the view also implies, not a source of knowledge but an expression of knowledge the subject already has. And I suggest the view need not limit memories to states that are in any way experience-like. This position offers a way to articulate the relations between episodic memory and related phenomena: factual memory, generic memory, remembering-how and anticipation. And it allows us to explain how we know which aspects of our episodic memory states to take seriously and which (such as the shift to an observer perspective on the remembered events) to treat as merely incidental.

This book offers a philosophical account of memory. Memory is remarkably interesting from a philosophical point of view. Our memories interact with mental states of other types in a characteristic way. They also have some associated feelings that other mental states lack. Our memories are special in terms of their representational capacity too, since we can have memories of objective events, and we can have memories of our own past experiences. Finally, our memories are epistemically special, in that (...) beliefs formed on the basis of our memories are protected from certain errors of misidentification and justified in a way which does not rely on any cognitive capacity other than memory. The aim of the book is to explain these features of memory. It proposes that memories have a particular functional role which involves past perceptual experiences and beliefs about the past and suggests that memories have a particular content as well; they represent themselves as having a certain causal origin. The book then accounts for the feelings associated with our memories as the experience of some of the things that our memories represent; things such as our own past experiences, or the fact the memories originate in those experiences. It also accounts for the special justification for belief afforded by our memories in terms of the content that memories have. The resulting picture is a unified account of several philosophically interesting aspects of memory. (shrink)

One striking feature of the contemporary modeling practice is its interdisciplinarity: the same function forms and equations, and mathematical and computational methods are being transferred across disciplinary boundaries. Within philosophy of science this interdisciplinary dimension of modeling has been addressed by both analogy and template-based approaches that have proceeded separately from each other. We argue that a more fully-blown account of model transfer needs both perspectives. We examine analogical reasoning and template application through a detailed case study on the transfer (...) of the Ising model from physics into neuroscience. Our account combines the analogy and template-based approaches through the notion of a model template that highlights the conceptual side of model transfer. (shrink)

In Tulving’s initial characterization, episodic memory was one of multiple memory systems. It was postulated, in pursuit of explanatory depth, as displaying proprietary operations, representations, and substrates such as to explain a range of cognitive, behavioural, and experiential phenomena. Yet the subsequent development of this research program has, paradoxically, introduced surprising doubts about the nature, and indeed existence, of episodic memory. On dominant versions of the ‘common system’ view, on which a single simulation system underlies both remembering (...) and imagining, there are no processes unique to memory to support robust generalizations with inductive potential. Eliminativism about episodic memory seems to follow from the claim that it has no dedicated neurocognitive system of its own. After identifying this under-noticed threat, we push back against modern eliminativists by surveying recent evidence that still indicates specialized mechanisms, computations, and representations that are distinctly mnemic in character. We argue that contemporary realists about episodic memory can retain lessons of the common system approach while resisting the further move to eliminativism. (shrink)

Are those judgments that we make on the basis of our memories immune to error through misidentification? In this paper, I discuss a phenomenon which seems to suggest that they are not; the phenomenon of observer memory. I argue that observer memories fail to show that memory judgments are not IEM. However, the discussion of observer memories will reveal an interesting fact about the perspectivity of memory; a fact that puts us on the right path towards explaining (...) why memory judgments are indeed IEM. The main tenet in the account of IEM to be proposed is that this aspect of memory is grounded, on the one hand, on the intentionality of perception and, on the other hand, on the relation between the intentionality of perception and that of memory.

Radical enactivism, an increasingly influential approach to cognition in general, has recently been applied to memory in particular, with Hutto and Peeters New directions in the philosophy of memory, Routledge, New York, 2018) providing the first systematic discussion of the implications of the approach for mainstream philosophical theories of memory. Hutto and Peeters argue that radical enactivism, which entails a conception of memory traces as contentless, is fundamentally at odds with current causal and postcausal theories, which (...) remain committed to a conception of traces as contentful: on their view, if radical enactivism is right, then the relevant theories are wrong. Partisans of the theories in question might respond to Hutto and Peeters’ argument in two ways. First, they might challenge radical enactivism itself. Second, they might challenge the conditional claim that, if radical enactivism is right, then their theories are wrong. In this paper, we develop the latter response, arguing that, appearances to the contrary notwithstanding, radical enactivism in fact aligns neatly with an emerging tendency in the philosophy of memory: radical enactivists and causal and postcausal theorists of memory have begun to converge, for distinct but compatible reasons, on a contentless conception of memory traces.

Working memory, an important posit in cognitive science, allows one to temporarily store and manipulate information in the service of ongoing tasks. Working memory has been traditionally classified as an explicit memory system – that is, as operating on and maintaining only consciously perceived information. Recently, however, several studies have questioned this assumption, purporting to provide evidence for unconscious working memory. In this paper, we focus on visual working memory and critically examine these studies as (...) well as studies of unconscious perception that seem to provide indirect evidence for unconscious working memory. Our analysis indicates that current evidence does not support an unconscious working memory store, though we offer independent reasons to think that working memory may operate on unconsciously perceived information.

Traces of many past events are often layered or superposed, in brain, body, and world alike. This often poses challenges for individuals and groups, both in accessing specific past events and in regulating or managing coexisting emotions or attitudes. We sometimes struggle, for example, to find appropriate modes of engagement with places with complex and difficult pasts. More generally, there can appear to be a tension between what we know about the highly constructive nature of remembering, whether it is drawing (...) on neural or worldly resources or both, and the ways that we need and use memory to make claims on the past, and to maintain some appropriate causal connections to past events. I assess the current state of work on situated affect and distributed memory, and the recent criticisms of the ‘dogma of harmony’ in these fields. I then deploy these frameworks to examine some affective dimensions of place memory, sketching a strongly distributed conception of places as sometimes partly constituting the processes and activities of feeling and remembering. These approaches also offer useful perspectives on the problems of how to engage – politically and aesthetically – with difficult pasts and historically burdened heritage. In assessing artistic interventions in troubled places, we can seek responsibly to do justice to the past while fully embracing the dynamic and contested constructedness of our present emotions, memories, and activities.

This paper introduces a new, expanded range of relevant cognitive psychological research on collaborative recall and social memory to the philosophical debate on extended and distributed cognition. We start by examining the case for extended cognition based on the complementarity of inner and outer resources, by which neural, bodily, social, and environmental resources with disparate but complementary properties are integrated into hybrid cognitive systems, transforming or augmenting the nature of remembering or decision-making. Adams and Aizawa, noting this distinctive complementarity (...) argument, say that they agree with it completely: but they describe it as “a non-revolutionary approach” which leaves “the cognitive psychology of memory as the study of processes that take place, essentially without exception, within nervous systems.” In response, we carve out, on distinct conceptual and empirical grounds, a rich middle ground between internalist forms of cognitivism and radical anti-cognitivism. Drawing both on extended cognition literature and on Sterelny’s account of the “scaffolded mind” (this issue), we develop a multidimensional framework for understanding varying relations between agents and external resources, both technological and social. On this basis we argue that, independent of any more “revolutionary” metaphysical claims about the partial constitution of cognitive processes by external resources, a thesis of scaffolded or distributed cognition can substantially influence or transform explanatory practice in cognitive science. Critics also cite various empirical results as evidence against the idea that remembering can extend beyond skull and skin. We respond with a more principled, representative survey of the scientific psychology of memory, focussing in particular on robust recent empirical traditions for the study of collaborative recall and transactive social memory. We describe our own empirical research on socially distributed remembering, aimed at identifying conditions for mnemonic emergence in collaborative groups. Philosophical debates about extended, embedded, and distributed cognition can thus make richer, mutually beneficial contact with independently motivated research programs in the cognitive psychology of memory.

Though researchers often refer to memory as if it were a unitary phenomenon, a natural kind, the apparent heterogeneity of the various "kinds" of memory casts doubt on this default view. This paper argues, first, that kinds of memory are individuated by memory systems. It argues, second, for a view of the nature of kinds of memory informed by the tri-level hypothesis. If this approach to kinds of memory is right, then memory is (...) not in fact a natural kind. (shrink)

Many authors claim that being conscious constitutively involves being self-conscious, or conscious of oneself. This claim appears to be threatened by reports of `selfless' episodes, or conscious episodes lacking self-consciousness, recently described in a number of pathological and nonpathological conditions. However, the credibility of these reports has in turn been challenged on the following grounds: remembering and reporting a past conscious episode as an episode that one went through is only possible if one was conscious of oneself while undergoing it. (...) Call this the Memory Challenge. This paper argues that the Memory Challenge fails to undermine the credibility to reports of selfless episodes, because it rests on problematic assumptions about episodic memory. The paper further argues that we should distinguish between several kinds of self-representation that may be involved in the process of episodic remembering, and that once we do so, it is no longer mysterious how one could accurately remember and report a selfless episode as an episode that one went through. Thus, we should take reports of this kind seriously, and view them as credible counter-examples to the claim that consciousness constitutively involves self-consciousness. (shrink)

Collaborative remembering, in which two or more individuals cooperate to remember together, is an ordinary occurrence. Ordinary though it may be, it challenges traditional understandings of remembering as a cognitive process unfolding within a single subject, as well as traditional understandings of memory knowledge as a justified memory belief held within the mind of a single subject. Collaborative memory has come to be a major area of research in psychology, but it has so far not been investigated (...) in epistemology. In this chapter, we attempt an initial exploration of the epistemological implications of collaborative memory research, taking as our starting point the “extended knowledge” debate which has resulted from the recent encounter between extracranialist theories of cognition and externalist theories of knowledge (Carter et al., 2014; Carter et al., forthcoming). Various forms of socially and technologically augmented memory have played important roles in the extended knowledge debate, but the debate has so far not taken collaborative memory, in particular, into account. We will argue that collaborative memory supports a novel externalist theory of knowledge: distributed reliabilism. Distributed reliabilism departs in two important respects from both traditional reliabilism (Goldman, 2012) and updated theories such as extended (Goldberg, 2010) and social reliabilism (Goldman, 2014). First, it acknowledges that belief-forming processes may extend extracranially to include processing performed both by other subjects and by technological artifacts. Second, it acknowledges that distributed sociotechnical systems themselves may be knowing subjects. Overall, then, the main aim of the chapter is to draw out the philosophical implications of psychological research on collaborative memory. But our argument will also suggest that it may be useful to broaden the standard conception of collaborative memory to include not only the sorts of direct interactions among subjects that have been the focus of psychological research so far but also a range of more indirect, technology-supported and -mediated interactions, and it thus has implications for psychology as well.
