We argue that cognitive models can provide a common ground between human users and deep reinforcement learning (Deep RL) algorithms for purposes of explainable artificial intelligence (AI). Casting both the human and learner as cognitive models provides common mechanisms to compare and understand their underlying decision-making processes. This common grounding allows us to identify divergences and explain the learner's behavior in human understandable terms. We present novel salience techniques that highlight the most relevant features in each model's decision-making, as well (...) as examples of this technique in common training environments such as Starcraft II and an OpenAI gridworld.

Katzav and Vaesen have argued that control by analytic philosophers of key journals, philosophy departments and at least one funding body plays a substantial role in explaining the emergence of analytic philosophy into dominance in the Anglophone world and the corresponding decline of speculative philosophy. They also argued that this use of control suggests a characterisation of analytic philosophy as, at the institutional level, a sectarian form of critical philosophy. I test these hypotheses against data about philosophy job hires at (...) key philosophy departments in the USA during the period 1930-1979, and against data about PhD completions during the period 1956-1965. I argue, further, that Katzav and Vaesen’s hypotheses can fully explain the data and are more fully able to do so than are some other key accounts of the emergence of analytic philosophy in the USA.

As technology improves, artificial systems are increasingly able to behave in human-like ways: holding a conversation; providing information, advice, and support; or taking on the role of therapist, teacher, or counsellor. This enhanced behavioural complexity, we argue, encourages deeper forms of affective engagement on the part of the human user, with the artificial agent helping to stabilise, subdue, prolong, or intensify a person's emotional condition. Here, we defend a fictionalist account of human/AI interaction, according to which these encounters involve an (...) elaborate practise of imaginative pretence: a make-believe in which the artificial agent is attributed a life of its own. We attend, specifically, to the temporal characteristics of these fictions, and to what we imagine artificial agents are doing when we are not looking at them. (shrink)

In the contemporary debate on free will, most philosophers assume that the defense of libertarianism implies the defense of the notion of alternative possibilities. This article discusses this presupposition by showing that it is possible to build a libertarianism without alternative possibilities, apparently more robust than libertarianism with alternative possibilities. Inspired by Bergson, this nonclassical libertarianism challenges the idea that all causation implies the actualization of a predetermined possibility (an idea shared by determinism and classical libertarianism). Moreover, it challenges the (...) idea that free will is a mere choice between prefixed possibilities: for this libertarianism, free will is the result of a creative process of the mind—an entirely causal process whose outcome is not, however, predetermined. This nonclassical libertarianism describes the process of forming a will in a more realistic way than classical libertarianism does. Furthermore, it is not threatened by the problem of chance.

An introduction to the philosophy of mathematics grounded in mathematics and motivated by mathematical inquiry and practice. In this book, Joel David Hamkins offers an introduction to the philosophy of mathematics that is grounded in mathematics and motivated by mathematical inquiry and practice. He treats philosophical issues as they arise organically in mathematics, discussing such topics as platonism, realism, logicism, structuralism, formalism, infinity, and intuitionism in mathematical contexts. He organizes the book by mathematical themes--numbers, rigor, geometry, proof, computability, incompleteness, (...) and set theory--that give rise again and again to philosophical considerations.

Grace A. de Laguna was an American philosopher of exceptional originality. Many of the arguments and positions she developed during the early decades of the twentieth century later came to be central to analytic philosophy. These arguments and positions included, even before 1930, a critique of the analytic-synthetic distinction, a private language argument, a critique of type physicalism, a functionalist theory of mind, a critique of scientific reductionism, a methodology of research programs in science and more. Nevertheless, de Laguna identified (...) herself as a defender of the speculative vision of philosophy, a vision which, in her words, “analytic philosophy condemns.” I outline her speculative vision of philosophy as well as what is, in effect, an argument she offers against analytic philosophy. This is an argument against the view that key parts of established opinion, e.g., our best theoretical physics or most certain common sense, should be assumed to be true in order to answer philosophical questions. I go on to bring out the implications of her argument for the approaches to philosophy of Bertrand Russell, Willard V. Quine and David Lewis, and I also compare the argument to recent, related arguments against analytic philosophy. I will suggest that de Laguna offers a viable critique of analytic philosophy and an alternative approach to philosophy that meets this critique. (shrink)

Drawing upon the life and work of S. Kay Toombs, I explore the impact and import of phenomenological accounts of disability for the existentialist tradition. Through the case of multiple sclerosis, a noncongenital, late-onset, and degenerative disability, I show how the general structures that emerge from its lived experience largely support a mere-difference view of disability and highlight the need for an equitably habitable world. I further argue that phenomenological accounts of disability demonstrate accessibility to be the defining feature of (...) what it means to be embodied as we are. I conclude with a discussion of the more general philosophical relationship between disability, embodiment, and existentialism. (shrink)

Ethical extensionism is a common argument pattern in environmental and animal ethics, which takes a morally valuable trait already recognized in us and argues that we should recognize that value in other entities such as nonhuman animals. I exposit ethical extensionism’s core argument, argue for its validity and soundness, and trace its history to 18th century progressivist calls to expand the moral community and legal franchise. However, ethical extensionism has its critics. The bulk of the paper responds to recent criticisms, (...) including (1) environmental ethicists’ objection against its austere conception of moral value (2), feminist ethicists’ claim that extensionism fails to account for the moral significance of difference, (3) disability theorists’ concern that ethical extensionist arguments are offensive, and (4) animal rights theorists’ lament that extensionism is a practical failure. While something is to be gained from each criticism, I argue that they ultimately fail and that extensionism remains compelling. (shrink)

I develop Tetsurō Watsuji’s relational model of the self as “betweenness”. I argue that Watsuji’s view receives support from two case studies: solitary confinement and dementia. Both clarify the constitutive interdependence between the self and the social and material contexts of “betweenness” that define its lifeworld. They do so by providing powerful examples of what happens when the support and regulative grounding of this lifeworld is restricted or taken away. I argue further that Watsuji’s view helps see the other side (...) of this deprivation, how reconstructing aspects of betweenness is, at the same time, a reconstruction of the self. I conclude by briefly indicating further consequences of this view. (shrink)

Some theorists, ranging from W. James to contemporary psychologists, have argued that forgetting is the key to proper functioning of memory. The authors elaborate on the notion of beneficial forgetting by proposing that loss of information aids inference heuristics that exploit mnemonic information. To this end, the authors bring together 2 research programs that take an ecological approach to studying cognition. Specifically, they implement fast and frugal heuristics within the ACT-R cognitive architecture. Simulations of the recognition heuristic, which relies on (...) systematic failures of recognition to infer which of 2 objects scores higher on a criterion value, demonstrate that forgetting can boost accuracy by increasing the chances that only 1 object is recognized. Simulations of the fluency heuristic, which arrives at the same inference on the basis of the speed with which objects are recognized, indicate that forgetting aids the discrimination between the objects' recognition speeds.

Biocentrism, a prominent view in environmental ethics, is the notion that all and only individual biological organisms have moral status, which is to say that their good ought to be considered for its own sake by moral agents. I argue that biocentrism suffers two serious problems: the Origin Problem and the Normativity Problem. Biocentrism seeks to avoid the absurdity that artifacts have moral status on the basis that organisms have naturalistic origins whereas artifacts do not. The Origin Problem contends that, (...) contra biocentrism, an entity’s origin is not relevant to whether that entity has moral status. The Normativity Problem is that biocentrists are preoccupied with accounting for the goods or interests of nonsentient organisms yet fail to establish why interests so construed confer moral status; biocentrism fails to bridge the good-ought gap. It is shown how these problems emerge in three prominent book-length works representative of the biocentrists’ positions over three decades: Paul Taylor’s Respect for Nature, Gary Varner’s In Nature’s Interests?, and Nicholas Agar’s Life’s Intrinsic Value. At minimum, these criticisms suggest that biocentrism is crucially incomplete as a moral framework at present and, optimistically, where more work remains to be done. If biocentrism really is dead, then moral status should be restricted to a more plausible locus such as sentience or rationality, the value of organisms needs a different expression, and environmental ethics needs an axiological foundation different than bare life.

Since the publication of Wahrheit und Methode in 1960 (Tfibingen), Gadamer's hermeneutics has called forth a varied and fruitful response from the Continent, without receiving anything near the same attention from the English-speaking world. Though E. D. Hirsch thought Gadamer sufficiently important in 1965 to merit an early rebuttal and rehabilitation (Validity in Interpretation [New Haven, Conn., 1967], pp. 245-64), Wahrheit und Methode remained unread in England and America, partly because a translation was not available until 1975 (Truth and Method, (...) ed. Garrett Barden and John Cumming [New York]). Even after that date, Gadamer's influence on Anglo-American debate has been largely secondhand, filtering in through such figures as Paul Ricoeur and Jiurgen Habermas. But a renewed interest in the question of what we are to make of tradition, no doubt spurred in large measure by deconstruction's effort to unmake it, has lent Gadamer a new pertinence. One sign that his stock is on the rise is the publication of Joel Weinsheimer's Gadamer's Hermeneutics, a much needed and admirably written introduction to Truth and Method that should push its value even higher. -- JSTOR (June 12, 2012.).

In A Question of Time, Joel Pearl offers a new reading of the foundations of psychoanalytic thought, indicating the presence of an essential lacuna that has been integral to psychoanalysis since its inception. Pearl returns to the moment in which psychoanalysis was born, demonstrating how Freud had overlooked one of the most principal issues pertinent to his method: the question of time. The book shows that it is no coincidence that Freud had never methodically and thoroughly discussed time and (...) that the metaphysical assumption of linear time lies at the very heart of Freudian psychoanalysis. Pearl’s critical reading of Freud develops through an original dialogue that he creates with the philosophy of Martin Heidegger and, specifically, with the German philosopher’s notion of temporality. Pearl traces the encounter between Freud and Heidegger by observing the common inspiration shaping their thinking: philosopher Franz Brentano, who taught both Freud and Edmund Husserl, Heidegger’s mentor. The book travels down an alternate path, one overlooked by Freudian thought – a path leading from Brentano, through Husserl and onto Heidegger’s notion of time, which is founded on the ecstatic’ interrelation of past, present and future.

Introspection is paradoxical in that it is simultaneously so compelling yet so elusive. This paradox emerges because although experience itself is indisputable, our ability to explicitly characterize experience is often inadequate. Ultimately, the accuracy of introspective reports depends on individuals' imperfect ability to take stock of their experience. Although there is no ideal yardstick for assessing introspection, examination of the degree to which self-reports systematically covary with the environmental, behavioural, and physiological concomitants of experience can help to establish the correspondence (...) between meta-consciousness and experience. We illustrate the viability of such an approach in three domains, imagery, mind-wandering, and hedonic appraisal, identifying both the situations in which introspections appear to be accurate and those in which they seem to diverge from underlying experience. We conclude with a discussion of the various factors that may cause meta-consciousness to misrepresent experience. (shrink)

Given that as much as half of human thought arises in a stimulus independent fashion, it would seem unlikely that such thoughts would play no functional role in our lives. However, evidence linking the mind-wandering state to performance decrement has led to the notion that mind-wandering primarily represents a form of cognitive failure. Based on previous work showing a prospective bias to mind-wandering, the current study explores the hypothesis that one potential function of spontaneous thought is to plan and anticipate (...) personally relevant future goals, a process referred to as autobiographical planning. The results confirm that the content of mind-wandering is predominantly future-focused, demonstrate that individuals with high working memory capacity are more likely to engage in prospective mind-wandering, and show that prospective mind-wandering frequently involves autobiographical planning. Together this evidence suggests that mind-wandering can enable prospective cognitive operations that are likely to be useful to the individual as they navigate through their daily lives. (shrink)

This paper pursues two main aims. First, it distinguishes two kinds of improvisation: expert and inexpert. Expert improvisation is a (usually artistic) practice that the agent consciously sets as their goal and is evaluated according to (usually artistic) standards of improvisation. Inexpert improvisation, by contrast, supports and structures the agent’s action as it moves them towards their (usually everyday life) goals and is evaluated on its success leading the agent to the achievement of those goals. The second aim is to (...) describe inexpert improvisation as a robustly distributed affair, one that involves the ongoing integration of embodied practices with social and material resources within our surrounding environments. On the wide approach to improvisation fostered in this paper, inexpert improvisation is claimed to be our default way of inhabiting our world. (shrink)

Contrastive epistemologists say knowledge displays the ternary relation “S knows p rather than q”. I argue that “S knows p rather than q” is often equivalent to “S knows p rather than not-p” and hence equivalent to “S knows p”. The result is that contrastive knowledge is often binary knowledge disguised.

Simple heuristics exploit basic human abilities, such as recognition memory, to make decisions based on sparse information. Based on the relative speed of recognizing two objects, the fluency heuristic infers that the one recognized more quickly has the higher value with respect to the criterion of interest. Behavioral data show that reliance on retrieval fluency enables quick inferences. Our goal with the present functional magnetic resonance imaging study was to isolate fluency-heuristic-based judgments to map the use of fluency onto specific (...) brain areas that might give a better understanding of the heuristic’s underlying processes. Activation within the claustrum for fluency heuristic decisions was found. Given that claustrum activation is thought to reflect the integration of perceptual and memory elements into a conscious gestalt, we suggest this activation correlates with the experience of fluency.

As research on mind wandering has accelerated, the construct’s defining features have expanded and researchers have begun to examine different dimensions of mind wandering. Recently, Christoff and colleagues have argued for the importance of investigating a hitherto neglected variety of mind wandering: “unconstrained thought,” or, thought that is relatively unguided by executive-control processes. To date, with only a handful of studies investigating unconstrained thought, little is known about this intriguing type of mind wandering. Across two experiments, we examined, for the (...) first time, whether changes in task demand influence rates of constrained versus unconstrained thoughts. In both experiments, participants completed either an easy (0-back) or hard (2-back) task and responded to intermittently presented thought probes that gauged thought constraint throughout the task. In Experiment 1, we found that participants completing the easy task engaged in unconstrained thoughts more frequently than those completing the difficult task. In Experiment 2, we replicated this result and further demonstrated manipulations of unconstrained thought while also measuring task-relatedness (a common dimension of mind wandering). Finally, exploratory analyses showed associations between constrained thought and age, verbal intelligence, and an assessment of flow (‘deep effortless concentration’), thereby adding further evidence to indicate a dissociation between task-relatedness and constraint. We discuss the methodological and theoretical applications of our findings to the burgeoning field of research on unconstrained thought. (shrink)

This book is concerned with the role of intuitions in the justification of philosophical theory. The author begins by demonstrating how contemporary philosophers, whether engaged in case-driven analysis or seeking reflective equilibrium, rely on intuitions as evidence for their theories. The author then provides an account of the nature of philosophical intuitions and distinguishes them from other psychological states. Finally, the author defends the use of intuitions as evidence by demonstrating that arguments for skepticism about their evidential value are either (...) self-defeating or guilty of arbitrary and unjustified partiality towards non-intuitive modes of knowledge.

[This piece is written for those working in social gerontology and aging studies, with the aim of bringing insights from disability studies and philosophy of disability to bear on enduring debates in those fields.] The guiding question of humanistic age-studies—What does it mean to grow old?—cannot be answered without reflecting on disability. This is not simply because growing old invariably means becoming impaired in various ways, but also because the discriminations and stigmas involved in ageism are often rooted in ableism. (...) We here draw on research in the philosophy of disability as well as the interdisciplinary field of disability studies to explore the relationship between ageism and ableism. (shrink)

This entry addresses the nature and epistemological role of intuition by considering the following questions: (1) What are intuitions?, (2) What roles do they serve in philosophical (and other “armchair”) inquiry?, (3) Ought they serve such roles?, (4) What are the implications of the empirical investigation of intuitions for their proper roles?, and (5) What is the content of intuitions prompted by the consideration of hypothetical cases?

Blasius of Parma deals with intensification and remission of accidental forms, and the related concept of « latitude » in at least three texts : the Questiones de latitudinibus formarum, the Questio disputata de intensione et remissione formarum and Question 10 on Book V of the Physics. The paper is focussed on the two last. Blasius discusses theses about the ontological status of qualities and their relation to their subject of inherence through the issue of their intensification or weakening, at (...) the borderline of physics and metaphysics. In the same time, he takes sides for the calculating procedures that were on debate since the beginning of the 14th century. In binding the quality and its subject closely together, Blasius does not go as far as the Oxford Calculators in the mathematisation of intensive magnitudes. Nonetheless, he does attempt to integrate the new tools into his physics and his ontology. (shrink)

This chapter canvases a number of ways that issues surrounding disability intersect with social epistemology. We begin with a discussion of how social epistemology as a field and debates concerning epistemic injustice in particular would benefit from further (a) engaging the fields of disability studies and philosophy of disability and (b) more directly addressing the problem of ableism. In section two, we turn to issues of testimony, “intuitive horribleness,” and their relationship to debates concerning disability and well-being. We address how (...) the regular lack of uptake of disabled people’s testimony can lead to a number of structural rather than merely individual epistemic injustices, and we also consider how the very nature of some disabilities make testimonial issues more complicated. We conclude by discussing various norms of social interaction and how they can systematically disadvantage Autistic people in particular with respect to all the issues discussed herein. (shrink)

This article is one in a series that develops the concept of logomachy. Logomachy is a philosophy of semantics or sense that takes into consideration the thermodynamic status of things in the world (their quamity). In particular, this article, looks at Gilbert Simondon’s claim that the laws of thought (Identity, Contradiction and the Excluded Middle) do not hold once certain thermodynamic states such as metastability (in between stability and instability) are taken into account. This article formulates, through a method I (...) term transduction (the mutual development of concepts between domains), novel logical laws that fit more adequately the way things thermodynamically are in the world. To do this, the article turns to the presocratic philosopher Heraclitus to rethink the logos as a conflictual site of meaning where things, and their capacity to make-sense, is conditioned by energetic investment, where difference is the condition of sameness.

This book offers an introduction to critical thinking for sociologists. Critical thinking involves the evaluation of arguments. Because sociologists tend to use particular forms of argumentation, it is helpful to consider how such arguments might be evaluated. Taking these matters into consideration can improve sociological arguments.
