This paper addresses some apparent philosophical tensions between realism and enactivism by means of Charles Peirce’s pragmatism. Enactivism’s Mind-Life Continuity thesis has been taken to commit it to some form of anti-realist ‘world-construction’ which has been considered controversial. Accordingly, a new realist enactivism is proposed by Zahidi (Phenomenology and the Cognitive Sciences 13(3), 2014), drawing on Ian Hacking’s ‘entity realism’, which places subjects in worlds comprised of the things that they can successfully manipulate. We review this attempt, and argue that (...) whilst Zahidi rightly urges enactivists towards ‘internal realism’, he cannot sustain a non-negotiable aspect of realism that is crucial for scientific progress – the claim that multiple subjects inhabit the same world. We explore Peirce’s pragmatism as an alternative solution, foregrounding his distinction between existence and reality, and his inquiry-based account of cognition. These theoretical innovations, we argue, fruitfully generalize Zahidi’s manipulation-based enactivist realism to a richer, inquiry-based enactivist realism. We explore how this realism’s pan-species monism about truth encourages and supports the investigation of non-human animal cognition, and conclude by considering some implications of our discussion for long-standing realism debates within pragmatism.

The viability of a naïve realist theory of memory was a lively debate for philosophers of mind in the first half of the twentieth century. More recently, though, naïve realism has been largely abandoned as a non-starter in the memory literature, with representationalism being the standard view held by philosophers of memory. But rather than being carefully argued, the dismissal of naïve realism is an assumption that sits at the back of much recent theorizing in the philosophy of memory. In (...) this paper, we identify three reasons why philosophers of memory have felt compelled to outright reject naïve realism. We argue that none of those reasons are successful. Thus, far from being a non-starter, we argue that naïve realism is a theoretical perspective that needs to be given serious consideration in current philosophy of memory debates. (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 questions of whether episodic memory is a propositional attitude, and of whether it has propositional content, are central to discussions about how memory represents the world, what mental states should count as memories, and what kind of beings are capable of remembering. Despite its importance to such topics, these questions have not been addressed explicitly in the recent literature in philosophy of memory. In one of the very few pieces dealing with the topic, Fernández (2006) provides a positive answer (...) to the initial questions by arguing that the propositional attitude view of memory, as I will call it, provides a simple account of how memory possesses truth-conditions. A similar suggestion is made by Byrne (2010) when he proposes that perception and episodic memory have the same kind of content, differing only in degree. Against the propositional attitude view, I will argue that episodic memory does not have propositional content, and therefore, that it is not a propositional attitude. My project here is, therefore, mainly critical. I will show that, if empirical work is to inform our philosophical theories of memory in any way, we have good reasons to deny, or at least to be skeptical, of the prospects of the propositional attitude view of episodic memory.

Alethism is the view that successful remembering only requires an accurate representation of a past event. It opposes the truth-and-authenticity view, according to which successful remembering requires both an accurate representation of a past event and an accurate representation of a past experience of that event. Alethism is able to handle problematic cases faced by the truth-and-authenticity view, but it faces an important challenge of its own: If successful remembering only requires accurately representing past events, then how is it possible (...) that our memories are also experienced as originating in past experiences of those events? I call this the puzzle of alethic memory. I argue that alethism can be reconciled with the claim that memories are experienced as originating in past experiences of those events—what I call the experience of first-handedness—if we conceive of the phenomenology of remembering in metacognitive terms. According to the metacognitive approach that I favor, the phenomenology of remembering is partly explained by what memory represents and partly explained by the existence of a metacognitive feeling that accompanies memory representations. I argue that accounting for the feeling of first-handedness in terms of the metacognitive feeling that accompanies memory representations allows us to solve the puzzle of alethic memory. (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).

This paper aims to provide a psychologically-informed philosophical account of the phenomenology of episodic remembering. The literature on epistemic or metacognitive feelings has grown considerably in recent years, and there are persuasive reasons, both conceptual and empirical, in favour of the view that the phenomenology of remembering—autonoetic consciousness, as Tulving influentially referred to it, or the feeling of pastness, as we will refer to it here—is an epistemic feeling, but few philosophical treatments of this phenomenology as an epistemic feeling have (...) so far been proposed. Building on insights from the psychological literature, we argue that a form of feeling-based metacognition is involved in episodic remembering and develop an integrated metacognitive feeling-based view that addresses several key aspects of the feeling of pastness, namely, its status as a feeling, its content, and its relationship to the first-order memories the phenomenology of which it provides.

We use Padoa's principle of independence of primitive symbols in axiomatic systems in order to show that time is dispensable in continuum thermodynamics, according to the axiomatic formulation of Gurtin and Williams. We also show how to define time by means of the remaining primitive concepts of Gurtin and Williams system. Finally, we introduce thermodynamics without time as a primitive concept.

The idea that episodic memory is a form of mental time travel has played an important role in the development of memory research in the last couple decades. Despite its growing importance in psychology, philosophers have only begun to develop an interest in philosophical questions pertaining to the relationship between memory and mental time travel. Thus, this paper proposes a more systematic discussion of the relationship between memory and mental time travel from the point of view of philosophy. I start (...) by discussing some of the motivations to take memory to be a form of mental time travel. I call the resulting view of memory the mental time travel view. I then proceed to consider important philosophical questions pertaining to memory and develop them in the context of the mental time travel view. I conclude by suggesting that the intersection of the philosophy of memory and research on mental time travel not only provides new perspectives to think about traditional philosophical questions, but also new questions that have not been explored before.

The idea that episodic memory is distinguished from semantic memory by the fact that it involves autonoetic consciousness, initially introduced by Tulving, has been influential not only in psychology but also in philosophy, where a variety of approaches to autonoesis and to its relationship to episodicity have been developed. This article provides a critical review of the available philosophical approaches. Distinguishing among representational, metacognitive, and epistemic accounts of autonoesis, it considers these in relation to objective and subjective conceptions of episodicity (...) and assesses them against immediacy and source criteria that any philosophical account of autonoesis should arguably aim to satisfy.

O que é o lembrar? Quando podemos dizer que um sujeito lembra um evento do passado? Essas são duas questões centrais na filosofia da memória, uma área que vem experimentando uma rápida expansão nos últimos anos. Por quase meio século, a teoria causal da memória, inicialmente proposta por Martin e Deutscher, dominou o debate sobre como devemos responder às duas questões iniciais. Mais recentemente, no entanto, a teoria causal se tornou alvo de duras críticas, o que motivou os filósofos da (...) memória a desenvolverem duas novas teorias sobre o lembrar: a teoria simulacionista e a teoria funcionalista. Neste artigo, exploramos essas teorias em mais detalhes com o objetivo de tornar mais claro quais são seus comprometimentos, assim como suas vantagens e desvantagens. (shrink)

Quasi-set theory $\cal Q$ allows us to cope with certain collections of objects where the usual notion of identity is not applicable, in the sense that $x = x$ is not a formula, if $x$ is an arbitrary term. $\cal Q$ was partially motivated by the problem of non-individuality in quantum mechanics. In this paper I discuss the range of explanatory power of $\cal Q$ for quantum phenomena which demand some notion of indistinguishability among quantum objects. My main focus is (...) on the double-slit experiment, a major physical phenomenon which was never modeled from a quasi-set-theoretic point of view. The double-slit experiment strongly motivates the concept of degrees of indistinguishability within a field-theoretic approach, and that notion is simply missing in $\cal Q$. Nevertheless, other physical situations may eventually demand a revision on quasi-set theory axioms, if someone intends to use it in the quantum realm for the purpose of a clear discussion about non-individuality. I use this opportunity to suggest another way to cope with identity in quantum theories. (shrink)

The 12 chapters cover 6 questions: I. What is the relationship between memory and imagination? II. Do memory traces have content? III. What is the nature of mnemonic confabulation? IV. What is the function of episodic memory? V. Do non-human animals have episodic memory? VI. Does episodic memory give us knowledge of the past?

In this essay I will argue that natural selection is more important to functional explanations than what has been thought in some of the literature in philosophy of biology. I start by giving a brief overview of the two paradigms cases of functional explanations: etiological functions and causal-role functions. i then consider one particular attempt to conciliate both perspectives given by David Buller. Buller's trial to conciliate both etiological functions and causal-role functions results in what he calls a weak etiological (...) theory. I argue that Buller has not succeeded in his construal of the weak etiological theory: he underestimates the role that selective processes have in functional explanations and so his theory may not be classified as an etiologial theory. As an alternative, I consider the account of etiological functions given by Ruth Millikan and I argue that Millikan's theory is more comprehensive to assess contentious case in biology like exaptations. Finally, I conclude by analyzing where the adoption of Millikan's theory leave us. I argue, contrary to Millikan and others, that once we assume the importance of natural selection in functional explanations, there is no strong reason to resist a linguistic reform of the word function and hence that the attempts to conciliate both etiological functions and causal-role functions are misplaced.

The structure of natural languages is usually studied from three major different but interconnected points of view: syntax, semantics, and pragmatics. If we consider that the main purpose of natural languages is communication, we should consider another dimension for languages, which deals with the influence of internal states of communicating individuals on meanings. Such a dimension we refer to as internalism. Within this context, internalism cannot be confused with psycholinguistics, in the same way pragmatics cannot be confused with sociolinguistics. In (...) particular, we argue, language is tied to its systematic use. This view leads us to a non-realist perspective on linguistics. We analyze the role of natural languages into dialogues, by comparing our proposal to the dialogical approach to logic, which considers a dialogue as a game. Within our approach, there is no way to guarantee that two parties involved in a dialogue are playing the same game, due to unavoidable differences in their respective internal states. Another contribution of this paper is to argue that semantics plays a more fundamental role than syntax in the cognitive acquisition of languages. (shrink)

We present an axiomatic framework for semantics that can be applied to natural and formal languages. Our main goal is to suggest a very simple mathematical model that describes fundamental cognitive aspects of the human brain and that can still be applied to artificial intelligence. One of our main results is a theorem that allows us to infer syntactical properties of a language out of its corresponding semantics. The role of pragmatics in semantics in our mathematical framework is also discussed.

I briefly discuss the epistemological role of quasi-set theory in mathematics and theoretical physics. Quasi-set theory is a first order theory, based on Zermelo-Fraenkel set theory with Urelemente. Nevertheless, quasi-set theory allows us to cope with certain collections of objects where the usual notion of identity is not applicable, in the sense that $x = x$ is not a formula, if $x$ is an arbitrary term. Basically, quasi-set theory offers us some sort of logical apparatus for questioning the need for (...) identity in some branches of mathematics and theoretical physics. I also use this opportunity to discuss a misunderstanding about quasi-sets due mainly to Nicholas J. J. Smith, who argues, in a general way, that sense cannot be made of vague identity. (shrink)

We recently showed that it is possible to deal withcollections of indistinguishable elementary particles (in thecontext of quantum mechanics) in a set-theoretical framework, byusing hidden variables. We propose in the presentpaper another axiomatics for collections of indiscernibleswithout hidden variables, where hidden predicates are implicitlyassumed. We also discuss the possibility of a quasi-settheoretical picture for quantum theory. Quasi-set theory, basedon Zermelo-Fraenkel set theory, was developed for dealing withcollections of indistinguishable, but, not identical objects.

Our main purpose here is to make some considerations about the definability of physical concepts like mass, force, time, space, spacetime, and so on. Our starting motivation is a collection of supposed definitions of closed system in the literature of physics and philosophy of physics. So, we discuss the problem of definitions in theoretical physics from the point of view of modern theories of definition. One of our main conclusions is that there are different kinds of definitions in physics that (...) demand different approaches. Within this context, we strongly advocate the use of the axiomatic method in order to discuss some issues concerning definitions. (shrink)

Quasi-set theory provides us a mathematical background for dealing with collections of indistinguishable elementary particles. In this paper, we show how to obtain the usual statistics (Maxwell–Boltzmann, Bose–Einstein, and Fermi–Dirac) into the scope of quasi-set theory. We also show that, in order to derive Maxwell–Boltzmann statistics, it is not necessary to assume that the particles are distinguishable or individuals. In other words, Maxwell–Boltzmann statistics is possible even in an ensamble of indistinguishable particles, at least from the theoretical point of view. (...) The main goal of this paper is to provide the mathematical grounds of a quasi-set theoretical framework for statistical mechanics. (shrink)
