Rationale: Deep brain stimulation (DBS) of the hippocampus is proposed for enhancement of memory impaired by injury or disease. Many pre-clinical DBS paradigms can be addressed in epilepsy patients undergoing intracranial monitoring for seizure localization, since they already have electrodes implanted in brain areas of interest. Even though epilepsy is usually not a memory disorder targeted by DBS, the studies can nevertheless model other memory-impacting disorders, such as Traumatic Brain Injury (TBI). Methods: Human patients undergoing Phase II invasive monitoring for (...) intractable epilepsy were implanted with depth electrodes capable of recording neurophysiological signals. Subjects performed a delayed-match-to-sample (DMS) memory task while hippocampal ensembles from CA1 and CA3 cell layers were recorded to estimate a multi-input, multi-output (MIMO) model of CA3-to-CA1 neural encoding and a memory decoding model (MDM) to decode memory information from CA3 and CA1 neuronal signals. After model estimation, subjects again performed the DMS task while either MIMO-based or MDM-based patterned stimulation was delivered to CA1 electrode sites during the encoding phase of the DMS trials. Each subject was sorted (post hoc) by prior experience of repeated and/or mild-to-moderate brain injury (RMBI), TBI, or no history (control) and scored for percentage successful delayed recognition (DR) recall on stimulated vs. non-stimulated DMS trials. The subject’s medical history was unknown to the experimenters until after individual subject memory retention results were scored. Results: When examined compared to control subjects, both TBI and RMBI subjects showed increased memory retention in response to both MIMO and MDM-based hippocampal stimulation. Furthermore, effects of stimulation were also greater in subjects who were evaluated as having pre-existing mild-to-moderate memory impairment. Conclusion: These results show that hippocampal stimulation for memory facilitation was more beneficial for subjects who had previously suffered a brain injury (other than epilepsy), compared to control (epilepsy) subjects who had not suffered a brain injury. This study demonstrates that the epilepsy/intracranial recording model can be extended to test the ability of DBS to restore memory function in subjects who previously suffered a brain injury other than epilepsy, and support further investigation into the beneficial effect of DBS in TBI patients.

Damn Great Empires! offers a new perspective on the works of William James by placing his encounter with American imperialism at the center of his philosophical vision. This book reconstructs James's overlooked political thought by treating his anti-imperialist Nachlass -- his speeches, essays, notes, and correspondence on the United States' annexation of the Philippines -- as the key to unlocking the political significance of his celebrated writings on psychology, religion, and philosophy. It shows how James located a craving for authority (...) at the heart of empire as a way of life, a craving he diagnosed and unsettled through his insistence on a modern world without ultimate foundations. Livingston explores the persistence of political questions in James's major works, from his writings on the self in The Principles of Psychology to the method of Pragmatism, the study of faith and conversion in The Varieties of Religious Experience, and the metaphysical inquiries in A Pluralistic Universe. Against the conventional view of James as a thinker who remained silent on questions of politics, this book places him in dialogue with a transatlantic critique of modernity, as well as with champions and critics of American imperialism, from Theodore Roosevelt to W. E. B. Du Bois, in order to excavate James's anarchistic political vision. Bringing the history of political thought into conversation with contemporary debates in political theory, Damn Great Empires! offers a fresh and original reexamination of the political consequences of pragmatism as a public philosophy.

Why does Aristotle not use the copulative wording for categorical propositions, but instead the clumsier terminological formulations (e. g. the B belongs to every A) in his syllogistic? The proposed explanations by Alexander, Lukasiewicz and Patzig: Aristotle wants to make clear the difference between subject and predicate, seems to be insufficient. In quantified categorical propositions, this difference is always sufficiently clear by the use of the pronouns going with the subject expressions. Aristotle opts for the terminological wording because in (...) premiss pairs of figures two and three he can thus suppress the middle term in one of the premisses and connect the major and minor term, using connecting particles. This renders the syllogisms more transparent. Had he used the copulative wording instead, he would have run into difficulties, in particular with o-propositions among the premisses (i. e. in Baroco and Bocardo) because in these cases the pronoun expressing the quantification would have to go with the subject term, the negation with the predicate.

Journal in the Night by THEODOR HAECKER Translated from the German by Alexander Dm PANTHEON BOOKS Printed in Great Britain for Pantheon Books Inc., 333 Sixth ...

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Neo-Baroque Aesthetics and Contemporary EntertainmentTheodore GracykNeo-Baroque Aesthetics and Contemporary Entertainment, by Angela Ndalianis. Cambridge, MA, and London: MIT Press, 2004, 323 pp., $34.95 cloth.Like the cliché about not judging a book by its cover, the prominence of the term "aesthetics" in a book's title is no indication of what one will find inside. Has the term become so elastic that it will now cover everything cultural? Or is (...) it the case, as in Angela Ndalianis's discussions of theme park rides and computer games, that the term applies to anything that has a parallel in earlier practices covered by this rubric? Ndalianis may be stretching it too far, for the book in question emphasizes parallels with baroque practices that predate Alexander Baumgarten's 1735 proposal to use "aesthetics" as the name of an emerging discipline concerned [End Page 115] with perception. We are alternately informed that the book explores the poetics, semiotics, and the "logic of contemporary media." But because Ndalianis holds that recent visual media involve a "specific system of perception" that arises from a "radical cultural transformation" (22-23), the term "aesthetics" may be as good as any other in conveying her purposes. For she is not concerned with artistic style—presumably the province of art historians. She is theorizing broadly about visual media by examining an assortment of media strategies found in the two eras and aims to identify their common "morphology" (19). Her sources are Fredric Jameson, Walter Benjamin, and Gilles Deleuze rather than, say, Kendall Walton, Noël Carroll, or Gregory Currie.Ndalianis's main idea is that there is a strong but not exact parallel between our own times and the visual forms favored in the seventeenth century. (For Ndalianis, the baroque period stretches from 1492 to the 1680s.) The two epochs involve similar cultural sensibilities and artistic practices, so if we understand baroque art and visual media, we will better understand what is going on in contemporary media. In short, the framing assumption is Shelley's dictum that art is the expression of the spirit of its time. More specifically, the design of modern entertainment media is argued to be very similar to a wide range of baroque entertainment and representational practice. But the similarity is not due to either awareness or imitation of baroque style. Each "logically emerged as a result of systemic and cultural transformations" peculiar to its own time (17). The similar "logic" of each period is thus seen as evidence that there are parallels in the "general tendencies" and consequent "dominant cultural sensibilities" of the two periods (17-21). Because hindsight is more reliable than precognition, a backward glance at the baroque may help us to better grasp our own historical and cultural context.Having outlined these proposals in a lengthy introduction, Ndalianis offers five chapters, each devoted to a specific parallel. All five chapters share a similar strategy. A different aspect of neo-baroque communication is highlighted, and one type of baroque art or entertainment is compared and contrasted with its neo-baroque counterpart, with at least one neo-baroque example explored in considerable detail.The introduction focuses on Jurassic Park (both the film and the theme park ride). Chapter 1 focuses on neo-baroque "narrative strategies," as first Don Quixote and its sequel and then the palace at Versailles are compared to the various Alien films and comic books. The main focus is "serial" art as an outgrowth of capitalism, generating "an aesthetics of repetition" enriched by its "rampant self-reflexivity" (69). Chapter 2 shifts to the baroque love of labyrinthine structure, with its "enforced circuitousness, planned chaos, choice among paths, intricacy, complexity, and an invitation to the audience to engage reflexively" in exploring the labyrinth (84). Ndalianis's baroque case is Pietro de Cortona's elaborate painted ceiling for the Palazzo Barberini in Rome. The neo-baroque counterpart is the Doom video game and its sequel, Doom II. Inexplicably, for a book with numerous illustrations, there are no visuals to display Doom for those unfamiliar with such games. Chapter 3 examines baroque cartography as a background for discussing geographic discovery and colonization, leading to the neo-baroque... (shrink)

Walter Benjamin's influence on Theodor Adorno centers on the former's early philosophy of language, which drew on manifold sources, including importantly the theological writings of Johann Georg Hamann. Adorno adapts this “expressivist” philosophy of language as part of a critique of Hegel's dialectic that forms the basis for Adorno's understanding of epistemology and social criticism. The result of this tempered influence is that Benjamin's and Adorno's projects share a great deal of common ground and vocabulary, but diverge in fundamental ways. (...) These tensions come to the fore in Adorno's 1930s criticisms of Benjamin's unfinished Arcades Project. Of particular import are their respective understandings of Benjamin's notion of a constellation. For Adorno the constellation is a response to the dialectical tension in the relation between subject and object, while for Benjamin it transcends that relation. (shrink)

No início deste ano, contemporânea a uma edição comemorativa dos quarenta anos deexistência do lnstitutus-Rainnmdus-Lullus em Freiburg i. Br., um tanto atrasada, mas nem por isso menos importante, apareceu a tradução alemã do Liber de gentili et tribus sapientibus,. Duas circunstâncias tornaram importante o aparecimento deste livro para todos os que se interessam por Ramon Llull e pela cultura catalã. Em primeiro lugar, por ser esta não somente a primeira edição completa desta obra em alemão, que substitui a edição selecionada, (...) muito fragmentária, de Xosé e Elisabeth Scheible1 mas, ao mesmo tempo, por ser a primeira tradução completa em língua alemã desta obra.2 Além disso, o fato de este livro aparecer numa tão conhecida editora como a de Philipp Reklam indica que o Buch vom Heiden und den drei Weisen será, pelo menos nos próximos anos, a obra de Llull pela qual os leitores alemães terão o primeiro contato com o fascinante pensamento do maiorquino. Esta obra, que representa uma importante contribuição para o discurso inter-religioso na Idade Média, presta-se verdadeiramente como introdução ao pensamento do Doctor muminatus e apresenta as características essenciais da análise combinatória de sua Ars, de forma altamente explícita e igualmente estética e literária. Constituem seu guia e base narrativa os diálogos de três sábios, representando as três grandes religiões, enquanto caminham por uma selva até a descoberta dum locua amoenus, magistralmente descrito, em meio do qual encontram cinco grandes árvores, em cujas folhas se acham gravadas as combinações binárias dos princípios básicos Julianos. Aqui os três sábios, e com eles o leitor, são conduzidos pela dama Inteligência, e com ajuda das árvores, na funcionalidade da análise combinatória Juliana, antes de exporem racionalmente aos desconfiados pagãos a confortadora verdade salvífica da respectiva fé de cada um. Com isso o tradutor e editor Theodor Pindl, que já se distinguiu com diversos trabalhos, especialmente sobre o Breviculum, satisfaz na sua versão, com poucas exceções,3 as qualidades tanto filosóficas como literárias da obra e produz um texto bastante legível. No entretanto, nao baseou sua tradução na edição crítica do texto catalão feita por Antoni Bonner,4 publicada em 1993 na série Nova edició de les obres de Ramon Llull, mas recorreu à edição latina de 1721, de Ivo Salzinger, reeditada em 1965. O que é de se admirar, pois a edição feita em Mainz por Ivo Sa!zinger, como é sabido, sofreu numerosas modificações no que diz respeito à ordem das frases e à escolha das palavras feitas pelo editor.

A special issue of_ New German Critique_ The posthumous publication of Theodor W. Adorno’s works on music continues to reveal the special relationship between music and philosophy in his thinking. These important works have not, however, received as much scholarly attention as they deserve. Contributors to this issue seek to provide insight into some of the key themes raised in these works, including the sociology of musical genre, the historical transformation of music from the "heroic" or high-bourgeois era to late (...) modernity, the meaning of both performance and listening in the era of mass communication, and the specific challenges or deformations of the radio on musical form, a theme that implicates many of the digital practices of our own age. There is much left to discover in these new publications, and they pose again, with renewed vigor, the question of Adorno’s _Aktualität_—his polyvalent, untranslatable term for, among other things, the intellectual relationship between the present and the past.

This chapter interrogates the figure “without soil” in relation to pivotal concerns in Theodor W. Adorno's thought. Freedom, the element of philosophy, proves itself as much in the conscious dismissal as in the rescuing return. The return is not that of something repressed, a claim suppressed by another claim, by the blank refusal to have anything to do with something. The fact that Adorno's thinking draws on dialectical motifs means that the conscious dismissal turns against what exists, against what is (...) merely natural, isolated, abstract in life; the life of the spirit that has freed itself from abstraction no longer sets itself in opposition to death. It no longer takes control of death as negativity and, for that very reason, no longer succumbs to it. If one wanted to revert to Kantian terminology, one could say that philosophy is concerned with neither inclination nor respect, but with favor. (shrink)

RESUMEN: El propósito del presente escrito es preguntarnos por el campo complejo que se abre en la confluencia de las trayectorias de Alexander Kluge y Theodor W. Adorno. Desarrollaremos, en primer lugar, algunos hitos históricos que permitan situarnos en el contexto de ese acercamiento. Luego, tomando como punto de partida el problema clave de la referencialidad de la imagen que, tanto para Kluge como para Adorno es central en las reflexiones sobre una estética propia del cine, abordaremos cuatro temas (...) que consideramos nos permiten repensar las relaciones de los dos teóricos: palabra e imagen, la idea de montaje, imagen y experiencia subjetiva y la cuestión de la recepción. ABSTRACT: The aim of this paper is to explore the complex convergence between the trajectories of Alexander Kluge and Theodor W. Adorno. In the first place, we develop some historical milestones that allow us to describe the context of this closeness. Then, taking as a starting point the key problem of the image referential -which for Kluge and Adorno is the main concern in the reflections on a particular aesthetics of film-, we will address four issues that let us rethink the relationship of the two of them: the idea of ​​montage, narrative and image, subjective experience and the matter of reception.

Four- Dimensionalism defends the thesis that the material world is composed of temporal as well as spatial parts. This defense includes a novel account of persistence over time, new arguments in favour of the four-dimensional ontology, and responses to the challenges four- dimensionalism faces." "Theodore Sider pays particular attention to the philosophy of time, including a strong series of arguments against presentism, the thesis that only the present is real. Arguments offered in favour of four- dimensionalism include novel arguments based (...) on time travel, the debate between spacetime substantivalists and relationalists, and vagueness. Also included is a comprehensive discussion of the paradoxes of coinciding material objects, and a novel resolution of those paradoxes based on temporal counterpart theory. In conclusion Sider replies to prominent objections to four- dimensionalism, including discussion of the problem of the rotating homogenous disk. (shrink)

Logic begins but does not end with the study of truth and falsity. Within truth there are the modes of truth, ways of being true: necessary truth and contingent truth. When a proposition is true, we may ask whether it could have been false. If so, then it is contingently true. If not, then it is necessarily true; it must be true; it could not have been false. Falsity has modes as well: a false proposition that could not have been (...) true is impossible or necessarily false; one that could have been true is merely contingently false. The proposition that some humans are over seven feet tall is contingently true; the proposition that all humans over seven feet tall are over six feet tall is necessarily true; the proposition that some humans are over seven feet tall and under six feet tall is impossible, and the proposition that some humans are over nine feet tall is contingently false. Of these four modes of truth, let us focus on necessity, plus a fifth: possibility. A proposition is possible if it is or could have been true; hence propositions that are either necessarily true, contingently true, or contingently false are possible. Notions that are similar to the modes of truth in being concerned with what might have been are called modal. Dispositions are modal notions, for example the disposition of fragility. Relatedly, there are counterfactual conditionals, for example “if this glass were dropped, it would break.” And the notion of supervenience is modal.1 But let us focus here on necessity and possibility. Modal words are notoriously ambiguous (or at least context-sensitive2). I may reply to an invitation to give a talk in England by saying “I can’t come; I have to give a talk in California the day before”. This use of “can’t” is perfectly appropriate. But it would be equally appropriate for me to say that I could cancel my talk in California (although that would be rude) and give the talk in England instead. What I cannot do is give both talks..

While it might seem prima facie plausible that divine foreknowledge is all that is needed for prophecy, this seems incorrect. To issue a prophecy, God hasto know not just how someone will act, but how someone would act were the prophecy issued. This makes some think that Middle Knowledge is required.I argue that Thomas Flint’s two Middle Knowledge based accounts of prophecy are unsatisfactory, but one of them can be repaired. However the resources needed for repair also yield a sketch (...) of a foreknowledge-only account of prophecy. (shrink)

Traditional debate on the metaphysics of gender has been a contrast of essentialist and social-constructionist positions. The standard reaction to this opposition is that neither position alone has the theoretical resources required to satisfy an equitable politics. This has caused a number of theorists to suggest ways in which gender is unified on the basis of social rather than biological characteristics but is “real” or “objective” nonetheless – a position I term social objectivism. This essay begins by making explicit the (...) motivations for, and central assumptions of, social objectivism. I then propose that gender is better understood as a real kind with a historical essence, analogous to the biologist’s claim that species are historical entities. I argue that this proposal achieves a better solution to the problems that motivate social objectivism. Moreover, the account is consistent with a post-positivist understanding of the classificatory practices employed within the natural and social sciences. (shrink)

This volume makes available in English for the first time Adorno’s lectures on metaphysics. It provides a unique introduction not only to metaphysics but also to Adorno’s own intellectual standpoint, as developed in his major work Negative Dialectics. Metaphysics for Adorno is defined by a central tension between concepts and immediate facts. Adorno traces this dualism back to Aristotle, whom he sees as the founder of metaphysics. In Aristotle it appears as an unresolved tension between form and matter. This basic (...) split, in Adorno’s interpretation, runs right through the history of metaphysics. Perhaps not surprisingly, Adorno finds this tension resolved in the Hegelian dialectic. Underlying this dualism is a further dichotomy, which Adorno sees as essential to metaphysics: while it dissolves belief in transcendental worlds by thought, at the same time it seeks to rescue belief in a reality beyond the empirical, again by thought. It is to this profound ambiguity, for Adorno, that the metaphysical tradition owes its greatness. The major part of these lectures, given by Adorno late in his life, is devoted to a critical exposition of Aristotle’s thought, focusing on its central ambiguities. In the last lectures, Adorno’s attention switches to the question of the relevance of metaphysics today, particularly after the Holocaust. He finds in metaphysical experiences, which transcend rational discourse without lapsing into irrationalism, a last precarious refuge of the humane truth to which his own thought always aspired. This volume will be essential reading for anyone interested in Adorno’s work and will be a valuable text for students and scholars of philosophy and social theory. (shrink)

The Ukrainian translation of the work of the German neo-Marxist philosopher Theodor Adorno "Education after Auschwitz" is dedicated to the 75th anniversary of the liberation of prisoners of the Nazi concentration camp Auschwitz. In this work, which Theodor Adorno read as a report on Hesse Radio on April 18, 1966, the previous theme of special importance – the cultivation of a new, anti-ideological education in post-totalitarian society as a means of humanistic educational influence on this society – was continued. Adorno (...) suggested that his listeners see as a humanistic need for a post-totalitarian society to spread in its cultural space through the education the each person's understanding of own guilt for the Auschwitz tragedy. According to the philosopher, in this way, it is possible to restore the civilization of the coexistence of man and society, and it will make it impossible to repeat the horrors of the Auschwitz concentration camp. Another factor that should prevent the return of Auschwitz crimes, Adorno called the presence of knowledge about the genesis of an authoritarian character, which is the socio-psychological cause of the suffering of innocent people. Having considered the socio-cultural and anthropological factors of the emergence of an authoritarian character, Adorno identified the undoubted psychological dependence of the bearers of a manipulative character on the authoritarian government. The origins of the authoritarian government German philosopher found in the current state of European culture as one that has lost the spiritual energy needed for its own transformation. In accordance with his basic philosophical and educational beliefs, Adorno postulated the new education as an anti-ideological enlightenment, as knowledge that educates primarily politically aware young citizens, as an effective means of preventing the return of authoritarian government and, consequently, the repetition of Auschwitz.

In einem Brief nennt Adorno die "Negative Dialektik" kurz nach ihrem Erscheinen unter seinen Schriften "das philosophische Hauptwerk, wenn ich so sagen darf“. Dieser herausgehobenen Bedeutung, die das Werk für Adorno hatte, entspricht nicht nur die lange Zeit, die er mit der Abfassung des Buchs beschäftigt war, sondern auch die lange Geschichte, die ihre zentralen Motive in seinem Denken haben. Philosophische Begriffsklärung, die Arbeit an "Begriff und Kategorien“ einer negativen Dialektik, versteht Adorno dabei als dialektischen Übergang in inhaltliches Denken – (...) und so betreibt er sie auch hier. Das hat Konsequenzen für die Form des kooperativen Kommentars, der in diesem Band versucht wird. Adornos "Negative Dialektik" zu kommentieren, kann nur in dem Bewußtsein der unüberbrückbaren Kluft gelingen, die den Kommentar von diesem Text trennt. (shrink)

These seventeen lectures given in 1963 focus largely on Kant, 'a thinker in whose work the question of morality is most sharply contrasted with other spheres of existence'. After discussing a number of the Kantian categories of moral philosophy, Adorno considers other, seemingly more immediate general problems, such as the nature of moral norms, the good life, and the relation of relativism and nihilism. In the course of the lectures, Adorno addresses a wide range of topics, including: theory and practice, (...) ethics as bad conscience, the repressive character, the problem of freedom, dialectics in Kant and Hegel, the nature of reason, the moral law as a given, psychoanalysis, the element of the Absurd, freedom and law, the Protestant tradition of morality, Hamlet, self-determination, phenomenology, the concept of the will, the idea of humanity, The Wild Duck, and Nietzsche's critique of morality.

There is growing support for the view that social categories like men and women refer to “objective types” (Haslanger 2000, 2006, 2012; Alcoff 2005). An objective type is a similarity class for which the axis of similarity is an objective rather than nominal or fictional property. Such types are independently real and causally relevant, yet their unity does not derive from an essential property. Given this tandem of features, it is not surprising why empirically-minded researchers interested in fighting oppression and (...) marginalization have found this ontological category so attractive: objective types have the ontological credentials to secure the reality (and thus political representation) of social categories, and yet they do not impose exclusionary essences that also naturalize and legitimize social inequalities. This essay argues that, from the perspective of these political goals of fighting oppression and marginalization, the category of objective types is in fact a Trojan horse; it looks like a gift, but it ends up creating trouble. I argue that objective type classifications often lack empirical adequacy, and as a result they lack political adequacy. I also provide, and in reference to the normative goals described above, several arguments for preferring a social ontology of natural kinds with historical essences. (shrink)

The present study investigated whether individual differences between psychologists in thinking styles are associated with accuracy in diagnostic classification. We asked novice and experienced clinicians to classify two clinical cases of clients with two co-occurring psychological disorders. No significant difference in diagnostic accuracy was found between the two groups, but when combining the data from novices and experienced psychologists accuracy was found to be negatively associated with certain decision making strategies and with a higher self-assessed ability and preference for a (...) rational thinking style. Our results underscore the idea that it might be fruitful to look for explanations of differences in the accuracy of diagnostic judgments in individual differences between psychologists (such as in thinking styles or decision making strategies used), rather than in experience level.

A property, F, is maximal iff, roughly, large parts of an F are not themselves Fs.' Maximality makes trouble for a recent analysis of intrinsicality by Rae Langton and David Lewis.

There is broad agreement among social researchers and social ontologists that the project of dividing humans into social kinds should be guided by at least two methodological commitments. First, a commitment to what best serves moral and political interests, and second, a commitment to describing accurately the causal structures of social reality. However, researchers have not sufficiently analyzed how these two commitments interact and constrain one another. In the absence of that analysis, several confusions have set in, threatening to undermine (...) shared goals for the responsible modeling of social kinds of humans. This essay first explains the source and substance of these confusions. Then, by distinguishing different value-laden investigative questions into the classification of social kinds of humans, it sets out specific relations of dependence and constraint between empirically-driven investigations and value-driven investigations into social kinds of humans. The result is a more detailed and fruitful framework for thinking about the classification of social kinds that respects both normative interests and mind-independent causal regularities. (shrink)

For a novice this book is a mathematically-oriented introduction to modal logic, the discipline within mathematical logic studying mathematical models of reasoning which involve various kinds of modal operators. It starts with very fundamental concepts and gradually proceeds to the front line of current research, introducing in full details the modern semantic and algebraic apparatus and covering practically all classical results in the field. It contains both numerous exercises and open problems, and presupposes only minimal knowledge in mathematics. A specialist (...) can use the book as a source of references. Results and methods of many directions in propositional modal logic, from completeness and duality to algorithmic problems, are collected and systematically presented in one volume. (shrink)

In domains like stock brokerage, clinical psychiatry, and long‐term political forecasting, experts generally fail to outperform novices. Empirical researchers agree on why this is: experts must receive direct or environmental learning feedback during training to develop reliable expertise, and these domains are deficient in this type of feedback. A growing number of philosophers resource this consensus view to argue that, given the absence of direct or environmental philosophical feedback, we should not give the philosophical intuitions or theories of expert philosophers (...) greater credence than those of novice philosophers. This article has three objectives. The first is to explore several overlooked issues concerning the strategy of generalizing from empirical studies of non‐philosophical expertise to the epistemic status of philosophical expertise. The second is to explain why empirical research into a causal relationship between direct learning feedback and enhanced expert performance does not provide good grounds for abandoning a default optimism about the epistemic superiority of expert philosophical theories. The third is to sketch a positive characterization of learning feedback that addresses developmental concerns made salient by the empirical literature on expert performance for specifically theory‐driven or “armchair” domains like philosophy.
