The fields of machine learning (ML) and cognitive science have developed complementary approaches to computationally modeling human behavior. ML's primary concern is maximizing prediction accuracy; cognitive science's primary concern is explaining the underlying mechanisms. Cross-talk between these disciplines is limited, likely because the tasks and goals usually differ. The domain of e-learning and knowledge acquisition constitutes a fruitful intersection for the two fields’ methodologies to be integrated because accurately tracking learning and forgetting over time and predicting future performance based (...) on learning histories are central to developing effective, personalized learning tools. Here, we show how a state-of-the-art ML model can be enhanced by incorporating insights from a cognitive model of human memory. This was done by exploiting the predictive performance equation's (PPE) narrow but highly specialized domain knowledge with regard to the temporal dynamics of learning and forgetting. Specifically, the PPE was used to engineer timing-related input features for a gradient-boosted decision trees (GBDT) model. The resulting PPE-enhanced GBDT outperformed the default GBDT, especially under conditions in which limited data were available for training. Results suggest that integrating cognitive and ML models could be particularly productive if the available data are too high-dimensional to be explained by a cognitive model but not sufficiently large to effectively train a modern ML algorithm. Here, the cognitive model's insights pertaining to only one aspect of the data were enough to jump-start the ML model's ability to make predictions—a finding that holds promise for future explorations.

The aim of the paper is to consider from the perspective of contemporary anthropological linguistics the plausibility of universal, self-evident truths based on innate principles of cognition as they were propounded by Th omas Reid in his philosophy of common sense. The key problem is whether it is possible to trace any innate principles that would underlie common sense, practical knowledge and comprise truths which are selfevident, clear and directly accessible to all members of homo sapiens. Reid’s (...) assumptions are considered in the light of contemporary research on the conceptualization of colour, basic emotions, ethnobotany and spatial cognition. (shrink)

This paper presents a “frame” representation for common sense knowledge and uses it to formalize our knowledge of “mundane” painting (walls; not portraits). These frames. while designed to aid a computer program to understand stories about the painting process, should be of use to programs which attempt to actually carry out the activity. The paper stresses a “deep” understanding of the activity so that the representation indicates not only what steps to carry out, but also how to (...) do them, and why they should be done. To accomplish this, while at the same time preserving modularity and nonredundancy, a system of interframe pointers is introduced (the COMES‐FROM and LEADS‐TO pointers) which explain how or why something is done in tens of knowledge given in other frames. The paper proceeds by steadily deepening an initial English‐like description of the activity, and a context free grammar for the representation is included. (shrink)

Two kinds of epistemological sceptical paradox are reviewed and a shared assumption, that warrant to accept a proposition has to be the same thing as having evidence for its truth, is noted. 'Entitlement', as used here, denotes a kind of rational warrant that counterexemplifies that identification. The paper pursues the thought that there are various kinds of entitlement and explores the possibility that the sceptical paradoxes might receive a uniform solution if entitlement can be made to reach sufficiently far. Three (...) kinds of entitlement are characterized and given prima facie support, and a fourth is canvassed. Certain foreseeable limitations of the suggested antisceptical strategy are noted. The discussion is grounded, overall, in a conception of the sceptical paradoxes not as directly challenging our having any warrant for large classes of our beliefs but as crises of intellectual conscience for one who wants to claim that we do.

Anthropologists, through participant observation, play a large role in creating the very locus of their research: socio-cultural context. Challenges to the social-scientific ‘objectivity’ of this process draw strength from historical precedent, and serve a vital role in the larger anthropological project of confronting, as both critic and product of Western thought, its inherent tensions. In this paper, I focus on two types of epistemological bias that construct and reinforce the validity of objective knowledge: objectivism and literalism. An analysis of (...) ethnographic treatments of the philosophical concerns of metaphor theory and phenomenology of the senses illustrates both the difficulty and utility of taking on the epistemological underpinnings of social science.

Can we know anything for certain? There are those who think we can (traditionally labeled the "dogmatists") and those who think we cannot (traditionally labeled the "skeptics"). The theory of knowledge, or epistemology, is the great debate between the two. This book is an introductory and historically-based survey of the debate. It sides for the most part with the skeptics. It also develops out of skepticism a third view, fallibilism or critical rationalism, which incorporates an uncompromising realism about perception, (...) science, and the nature of truth. (shrink)

Subjectivists, taking the “collapse” of the observation-interpretation contrast much too seriously, are led to imagine that even perceptual knowledge is active. And therefore subject dependent. Turning the tables on this popular trend, I argue that even conceptual knowledge is passive. Kant’s epistemology is conceptual. But if also active, then incoherent. If synthetic a priori truths are to follow upon our mental activity, they were neither true nor, far less, a priori before that activity. “A priori” and “active” are (...) contradictory attributes of knowledge. As, indeed, are “a priori” and “subject-dependent” to begin with. Nothing a priori can be dependent on anything except itself, and least of all on the human subject. Kant does consider the active aspect of thought. The difference is that for him the more active it becomes, the less it is to be trusted. For we are no longer in the province of the Understanding, and its necessary truths, but in the realm of Pure Reason and its dialectical antinomies. Cognition activists who take a liking to Kant have simply mistaken Reason for the Understanding. And Reason is to Kant “the seat of all transcendental illusion”. (shrink)

What does an understanding of the first person pronoun “I” contribute to the understanding of a sentence involving “I”? This paper emphasizes that the first person pronoun is typically used as a tool of communication. We need to think not just about what it is to use the first person pronoun with understanding, but also what it is to understand someone else’s use of the first person pronoun. A plausible principle governing linguistic understanding via the conditions of adequacy upon reporting (...) speech entails what I call the symmetry constraint, which is that an account of the sense of “I” must leave open the possibility of sentences involving “I” saying the same thing as sentences involving “you”. One immediate consequence of the symmetry constraint is that we need to make a distinction between token-sense and type-sense, discussed in sections 1 and 2. A number of authors, most prominently Gareth Evans in his influential book The Varieties of Reference, have proposed that the sense of “I” needs to be elucidated, at least in part, in terms of the speaker’s sensitivity to forms of self-specifying information that have the property of being immune to error through misidentification relative to the first person pronoun. As emerges in section 3, however, this way of thinking about the sense of “I” is not compatible with the symmetry constraint, since it makes the sense of “I” private and unshareable. This leads in section 4 to an alternative proposal for doing justice to the insight that the sense of “I” reflects a distinctive way of being presented to oneself. On this proposal, the distinctive way in which I am presented to myself can be systematically related to the distinctive way in which I am presented to you. What matters is not that I am in receipt of distinctive types of information about myself, but rather that I have a distinctive ability to locate myself in objective space. On a plausible way of thinking about the individuation of cognitive abilities, this is an ability that you also can have and that underwrites both your understanding of “you” when you address me, and your understanding of “I” as uttered by me.

There is a social or collective sense of ‘knowledge’, as used, for example, in the phrase ‘the growth of scientific knowledge’. In this paper I show that social knowledge does not supervene on facts about what individuals know, nor even what they believe or intend, or any combination of these or other mental states. Instead I develop the idea that social knowing is an analogue to individual knowing, where the analogy focuses on the functional role of (...) social and individual knowing. (shrink)

The knowledge account of assertion (KAA) is the view that assertion is governed by the norm that the speaker should know what s/he asserts. It is not the purpose of this article to examine all the criticisms nor to try to give a full defence of KAA, but only to defend it against the charge of being normatively incorrect. It has been objected that assertion is governed by other norms than knowledge, or by no norm at all. It (...) seems to me, however, that a number of these criticisms are based on a number of misunderstandings of the notion of a norm and of the way it can regulated a given practice. Once we spell out in what sense knowledge can play a normative role in this context, the KAA appears much more plausible. (shrink)

The Kantian project of investigating the necessary structure of experience presupposes answers to three questions: what is the purpose of such an investigation, what is the source of necessary features of experience, and by what means is it possible to establish the necessary structure of experience? This paper is a critical examination of Strawson's answers to these questions in The Bounds of Sense and his later work. The realism that is implicit in The Bounds of Sense is much (...) more explicit in Strawson's later work but relies on problematic assumptions about the relationship between epistemology and metaphysics.

Claims concerning processes, claims of the form “xisφing”, have been the subject of renewed interest in recent years in the philosophy of action. However, this interest has frequently limited itself to noting certain formal features such claims have, and has not extended to a discussion of when they are true. This article argues that a claim of the form “xisφing” is true when what is happening withxis such that, if it is not interrupted, a φing will occur. It then applies (...) itself more directly to the case of action, arguing that when “xisφing” describesx's intentional action, it is true iffxis acting from a method she knows to be sufficient to φ, in the sense that if she is not interrupted in carrying out this method, she will φ. I use this criterion to argue that the carbon‐copier example Donald Davidson gives in “Intending” fails to refute Elizabeth Anscombe's claim that an agent who is φing intentionally knows that she is, because the agent in Davidson's example is not intentionally making the copies.

Since Michael Polanyi coined the term “tacit knowledge” in 1958, a huge amount of literature has been produced on this topic. Gascoigne and Thornton’s monograph represents one of the most recent attempts to clarify the concept of tacit knowledge.For other recent publications on tacit knowledge see Collins , Yu and Turner . In their engagement with various thinkers, most notably Polanyi, Ryle, Heidegger, Wittgenstein, John Searle, Hubert Dreyfus, and John McDowell, etc., the authors make impressive efforts to (...) situate the discussion of tacit knowledge in the context of mainstream philosophy. They shed new light on the concept of tacit knowledge by embedding it in contemporary debates, such as those on knowing how, rule-following, conceptualism, language maste .. (shrink)

We present a representation for reasoning and planning with an incomplete state description (open-world) called PSIPLAN-S. The presented formalism has several properties critical for application domains with a large degree of incompleteness in the state description, particularly, in domains with a large or unknown set of all objects. The formalism offers (1) considerably expressive state and goal description language, that includes limited universal quantification, (2) representation of sensing actions and knowledge goals, (3) a correct and complete state update procedure, (...) and (4) complete reasoning within a substantial subset of the language. The approach is illustrated by examples from a working system. (shrink)

Michael Dummett holds that the sense of a natural language proper name is part of its linguistic meaning. I argue that this view sits uncomfortably with Frege's observation that the sense of a natural language proper name varies from speaker to speaker. Moreover, the thesis under discussion is not supported by Frege's views on communication. Recently Richard Heck has tried to develop an argument which is intended to show that assertoric communication with sentences containing proper names is only (...) possible if Dummett's thesis or a version of it is true. I will challenge this argument and argue that it does not support Dummett's thesis. (shrink)

This work identifies Kant’s doctrine of inner sense as a central element within the ‘architectonic of pure reason’ of the first Critique, exposes its variant construals, and considers the implications of its problematicity for Kant’s theoretical philosophy most generally.

A commentary on a target article by Alison Gopnik (1993) How we know our minds: the illusion of first-person knowledge of intentionality. Focusing on evidence of how children acquire a theory of mind, this commentary argues that there are internal inconsistencies in theories that both argue for the functional role of conscious experiences and the irreducibility of those experiences to third-person viewable information processing.

The work of Michel Serres has been of significant value, yet remains under-utilized across the social sciences. In this review article the long-awaited translation of his The Five Senses is explored, with particular interest in its offerings for contemporary theories of the materiality of the human condition. Serres invites the reader into a diverse and rich world of sense, from localized sites of individual bodies to global landscapes of cities and countrysides. Not reducible to individual bodies or language, (...) class='Hi'>sense becomes the primary mode of relationality through which experience is produced. Such insights are explored in light of contemporary concerns regarding the constitution of bodies and materiality, which emphasize notions of movement and process. The distinction Serres makes between sense and language is argued to be valuable in terms of theories of virtuality that frame material embodiment as ineffable and beyond language. The article concludes by suggesting that Serres can aid re-attunement to sense, although not in a generalistic fashion, but as part of disciplinary specific engagements. (shrink)

The author presents a philosophical critique of the basic ideas of logical semantics, as developed by Frege, Russell, and Wittgenstein. He argues that these logicians understated the importance of the sense of linguistic expressions.

A team of leading contributors from both philosophical and literary backgrounds have been brought together in this impressive book to examine how works of literary fiction can be a source of knowledge. Together, they analyze the important trends in this current popular debate. The innovative feature of this volume is that it mixes work by literary theorists and scholars with work of analytic philosophers that combined together provide a comprehensive statement of the variety of ways in which works of (...) fiction can engage questions of worldly interest. It uses the problem of cognitive value to explore: literature’s contribution to ethical life literature’s ability to engage in social and political critique the role narrative plays in opening up possibilities of moral, aesthetic, experience and selfhood This remarkable volume will attract the attention of both literature and philosophy scholars with its statement of the various ways that literature and life take an interest in one another.

By taking the collective character of scientific research seriously, some philosophers have claimed that scientific knowledge is indeed collective knowledge. However, there is little clarity on what exactly is meant by collective knowledge. In this article, I argue that there are two notions of collective knowledge that have not been well distinguished: irreducibly collective knowledge (ICK) and jointly committed knowledge (JCK). The two notions provide different conditions under which it is justified to ascribe (...) class='Hi'>knowledge to a group. It is argued that ICK and JCK need to be approached independently, each of which can shed light on different aspects of science, knowledge production, and acceptance. (shrink)
