Kant's Reason develops a novel interpretation of Kant’s conception of reason and its philosophical significance, focusing on two claims. First, it argues that Kant presents a powerful model for understanding the unity of theoretical and practical reason as two manifestations of a unified capacity for theoretical and practical understanding (or “comprehension”). This model allows us to do justice to the deep commonalities between theoretical and practical rationality, without reducing either to the other. In particular, through it, we see why the (...) activities of both theoretical and practical reason are governed by a version of the Principle of Sufficient Reason, while also seeing why reason is essentially autonomous. At the same time, Kant's Reason also reads Kant as presenting us with a compelling picture of the role that reason (as a capacity or power) should play in a systematic approach to foundational philosophical questions. In doing so, it argues for an account of the fundamental norms that apply to rational beings that treats as fundamental neither substantive reasons or values nor merely structural rationality, but instead a robust conception of reason as a power or capacity — namely, the capacity for theoretical and practical understanding. The result is a form of “rational constitutivism” – one which contrasts both with the forms of “reasons fundamentalism” that are currently fashionable and the forms of “agency-first constitutivism” that have dominated much of Kantian metaethics. In this sense, the aim of the book is to vindicate Kant’s insistence that his philosophy represents nothing more or less than reason’s implicit self-understanding coming to explicit and systematic self-consciousness.

Quantum Theory and the Schism in Physics is one of the three volumes of Karl Popper’s Postscript to the Logic of scientific Discovery . The Postscript is the culmination of Popper’s work in the philosophy of physics and a new famous attack on subjectivist approaches to philosophy of science. Quantum Theory and the Schism in Physics is the third volume of the Postscript . It may be read independently, but it also forms part of Popper’s interconnected argument in the (...) Postscript . It presents Popper’s classic statement on quantum physics and offers important insights into his thinking on problems of method within science and physics as a whole. (shrink)

Realism and the Aim of Science is one of the three volumes of Karl Popper’s Postscript to the Logic of scientific Discovery. The Postscript is the culmination of Popper’s work in the philosophy of physics and a new famous attack on subjectivist approaches to philosophy of science. Realism and the Aim of Science is the first volume of the Postcript . Popper here formulates and explains his non-justificationist theory of knowledge: science aims at true explanatory theories, yet it can (...) never prove, or justify, any theory to be true, not even if is a true theory. Science must continue to question and criticise all its theories, even those that happen to be true. Realism and the Aim of Science presents Popper’s mature statement on scientific knowledge and offers important insights into his thinking on problems of method within science. (shrink)

This essay develops an interpretation of Kant’s conception of the faculty of reason as the capacity for what he calls "comprehension" (Begreifen). In doing so, it first discusses Kant's characterizations of reason in relation to what he describes as the two highest grades of cognition—insight and comprehension. Then it discusses how the resulting conception of reason relates to more familiar characterizations as the faculty for inference and the faculty of principles. In doing so, it focuses on how the idea of (...) reason as aiming at comprehension expresses the modesty about reason that is essential to Kant’s critical philosophy. It concludes by showing how this grounds an elegant account of the unity of theoretical and practical reason—one that does justice both to the "primacy" that Kant assigns to practical reason and the fact that this "primacy" is grounded in a more basic unity.

A central claim in abortion ethics is what might be called the Harm Claim – the claim that abortion harms the fetus. In this article, we put forward a simple and straightforward reason to reject the Harm Claim. Rather than invoking controversial assumptions about personal identity, or some nonstandard account of harm, as many other critics of the Harm Claim have done, we suggest that the aborted fetus cannot be harmed for the simple reason that it does not occupy any (...) well-being level.

According to internalism about rationality, the ir/rationality of a subject depends only on how things appear from her subjective perspective. According to culpabilism, rationality is a normative standard such that violations of rationality are (at least sometimes) blameworthy. According to a classical line of reasoning, culpabilism entails internalism. I argue that, to the contrary, culpabilism entails that internalism is false. The internalist cannot accommodate the possibility of culpable irrationality.

Consider the opening sentence of Tolkien’s The Hobbit: In a hole in the ground there lived a hobbit. By writing this sentence, Tolkien is making a fictional statement. There are two influential views of the nature of such statements. On the pretense view, fictional discourse amounts to pretend assertions. Since the author is not really asserting, but merely pretending, a statement such as Tolkien’s is devoid of illocutionary force altogether. By contrast, on the alternative make-believe view, fictional discourse prescribes that (...) the reader make-believe the content of the statement. In this paper, we argue that neither of these views is satisfactory. They both fail to distinguish the linguistic act of creating the fiction, for instance Tolkien writing the sentence above, from the linguistic act of reciting it, such as reading The Hobbit out loud for your children. As an alternative to these views, we propose that the essential feature of the author’s speech act is its productive character, that it makes some state of affairs obtain in the fiction. Tolkien’s statement, we argue, has the illocutionary force of a declaration. (shrink)

Teleosemantics has an indeterminacy problem. In an earlier publication, I argued that teleosemanticists may afford to be realists about indeterminacy, pointing to the phenomenon of vagueness as a case of really-existing semantic indeterminacy. Here, I continue that project by proposing two criteria of adequacy that a semantically indeterminate theory should meet: a criterion of theoretical adequacy and a criterion of extensional adequacy. I present reasons to think that indeterminate versions of teleosemantics can meet these criteria. I end by discussing vagueness, (...) concluding that it most likely is not the same kind of phenomenon as the semantic indeterminacy afflicting teleosemantics. (shrink)

In The Lesson of this Century Popper's purpose is to warn us against the increasing violence and egoism of our society. What solutions can we offer to the problems of the environment, demography and corruption? How can we prevent the violence our society engenders? How can we preserve our democratic system while at the same time paving the way for global peace? Popper believes that the philosopher has a duty to intervene in politics and he utters a clear call to (...) all of us to recognise our responsibilities. He reminds us that it is our actions which will create the world of tomorrow. The interviews in this volume were originally given to the Italian journalist Giancarlo Bosetti. The volume also includes the transcript of an interview about the moral dangers of television not previously available in English. (shrink)

This paper introduces deontic logic based on inquisitive semantics. A semantics for action formulas is introduced where each action formula is associated with a set of alternatives. Deontic operators are then interpreted as quantifying over all alternatives associated with the action formulas within their scope. It is shown how this construction provides solutions to problems related to free choice permissions and obligations, including issues concerning Hurford disjunctions. The main technical result is a complete axiomatization of the logic.

Freedom of information laws promote transparency by permitting individuals and organizations to obtain government documents. However, exemptions from disclosure are necessary to protect privacy and to permit government officials to deliberate freely. Deliberative language is often the most challenging and burdensome exemption to detect, leading to high processing costs and delays in responding to open-records requests. This paper describes a novel deliberative-language detection model trained on a new annotated training set. The deliberative-language detection model is a component of a decision-support (...) system for open-records requests under the US Freedom of Information Act, the FOIA Assistant, that ingests documents responsive to an open-records requests, suggests passages likely to be subject to deliberative language, privacy, or other exemptions, and assists analysts in rapidly redacting suggested passages. The tool’s interface is based on extensive human-factors and usability studies with analysts and is currently in operational testing by multiple US federal agencies. (shrink)

This article examines the relationship between epistemic freedom, and epistemic injustice and epistemic oppression. I situate epistemic freedom within the larger project of epistemic decolonisation and argue that epistemic freedom is central to both its positive and negative programme. Through exploring the intersections of the notion of epistemic freedom and the scholarship on epistemic injustice and oppression, I argue that one can think of epistemic injustices and oppression as infringements on epistemic freedom. I identify shared themes between the theorisation of (...) epistemic freedom and the literature on epistemic injustice and epistemic oppression, including silencing, active ignorance, and epistemic exploitation. I briefly explore each of these themes, identifying both intersections and divergences. Lastly, I draw on the literature on epistemic injustice and oppression to sharpen Ndlovu-Gatsheni’s (2018. Epistemic Freedom in Africa: Deprovincialization and Decolonization. London: Routledge) general conception of epistemic freedom and develop a tripartite structure for what substantial epistemic freedom entails. I argue that being epistemically free entails being able to choose one’s epistemic endeavours, having the means to pursue them, as well as being able to meaningfully partake in the shared endeavours of the epistemic communities that one belongs to.

In this paper, the (possible) role of model theory forstructuralism and structuralist definitions of ``reduction'' arediscussed. Whereas it is somewhat undecisive with respect tothe first point – discussing some pro's and con's ofthe model theoretic approach when compared with a syntacticand a structuralist one – it emphasizes that severalstructuralist definitions of ``reducibility'' do not providegenerally acceptable explications of ``reducibility''. This claimrests on some mathematical results proved in this paper.

In this paper I argue for the relevance of the philosophy of Hans-Georg Gadamer for contemporary feminist scholarship on epistemic injustice and oppression. Specifically, I set out to argue for the Gadamerian notion of hermeneutical openness as an important hermeneutic virtue, and a potential remedy for existing epistemic injustices. In doing so I follow feminist philosophers such as Linda Martín Alcoff and Georgia Warnke that have adopted the insights of Gadamer for the purpose of social and feminist philosophy. Further, this (...) paper is positioned in relation to a recent book chapter by Cynthia Nielsen and David Utsler in which they argue for the complementarity, and intersecting themes and concerns of Gadamer's hermeneutics and Miranda Fricker's work on epistemic injustice. However, Nielsen and Utsler solely focus on Fricker's conception of epistemic injustice and the two forms of epistemic injustice, testimonial injustice and hermeneutical injustice, that she identifies. In this paper I expand their analysis by considering other forms of epistemic injustice such as wilful hermeneutical ignorance and contributory injustice. Thus, this paper contributes to the budding literature on the relevance of Gadamer's work for the debates pertaining to epistemic injustice and oppression by expanding such analysis to other forms of epistemic injustice, and by further arguing for the strength of Gadamer's work in terms of offering relevant insights for the reduction and remedy of existing epistemic injustices.

Several recent discussions of metaphysics disavow existence-questions, claiming that they are metaphysically uninteresting because trivially settled in the affirmative by Moorean facts. This is often given as a reason to focus metaphysical debate instead on questions of grounding. I argue that the strategy employed to undermine existence-questions fails against its usual target: Quineanism. The Quinean can protest that the formulation given of their position is a straw man: properly understood, as a project of explication, Quinean metaphysics does not counsel us (...) to choose between obvious ordinary-language claims and absurd revisionist claims, even if appeal to Moorean facts is permitted.

Written in political exile during the Second World War and first published in 1945, Karl Popper's The Open Society and Its Enemies is one of the most influential books of the twentieth century. Hailed by Bertrand Russell as a 'vigorous and profound defence of democracy', its now legendary attack on the philosophies of Plato, Hegel and Marx exposed the dangers inherent in centrally planned political systems. Popper's highly accessible style, his erudite and lucid explanations of the thought of great (...) philosophers and the recent resurgence of totalitarian regimes around the world are just three of the reasons for the enduring popularity of The Open Society and Its Enemies , and for why it demands to be read both today and in years to come. This is the second of two volumes of The Open Society and Its Enemies. (shrink)

This paper investigates inquisitive extensions of normal modal logic with an existential modal operator taken as primitive. The semantics of the existential modality is generalized to apply to questions, as well as statements. When the generalized existential modality is applied to a question, the result is a statement that roughly expresses that each way of resolving the question is consistent with the available information. I study the resulting logic both from a semantic and from a proof-theoretic point of view. I (...) argue that it can be used for reasoning about a general notion of ignorance, and for reasoning about choice-offering permissions and obligations. The main technical results are sound and complete axiomatizations, both for the class of all Kripke frames, and for any class of frames corresponding to a canonical normal modal logic. (shrink)

This paper is a very early and very preliminary report of some of the findings from the research project, "Prehistoric Myths in Modern Political Philosophy." The project eventually lead to two books: "Prehistoric Myths in Modern Political Philosophy" and "the Prehistory of Private Property" (both coauthored by Grant S. McCall). The basic argument of the project is that influential, modern political theories often rely on dubious claims about prehistory. It examines the political philosophy literature to show how these claims are (...) used as essential premises in influential arguments. It then examines evidence from anthropology, archaeology, and history to show that these claims are dubious. This paper previews some of the early findings of the project that became those books. Please cite the books rather than this preliminary report. For info or access to the books, contact Karl at widerquist dot com. (shrink)

Zusammenfassung Die „romantische Liebe“ bildet unter modernen Bedingungen eine zentrale Quelle sozialer Anerkennung. Ihr nicht selten durch die Verwendung religiöser Semantik signalisierter Bedeutungszuwachs sorgt aber zugleich für eine Steigerung der Verletzlichkeit des einzelnen. Der damit beschriebenen spannungsvollen Eigenart, die der Anerkennungssphäre der Liebe unter modernen Bedingungen zukommt, wird in diesem Text nachgegangen. Dabei stehen zwei Autorinnen der Gegenwart, die sich mit den Ambivalenzen heutiger Liebesbeziehungen besonders eindrücklich auseinandergesetzt haben, im Fokus: die Kultursoziologin Eva Illouz und die Schriftstellerin Sally Rooney. Nach (...) einem einführenden Blick auf die den beiden Autorinnen gemeinsame Thematik, geht es um spezifische Unsicherheitserfahrungen, die sich mit dem Aufstieg der Liebe zu einer zentralen Anerkennungssphäre verbinden. Dann wird die für romantische Beziehungen ebenfalls charakteristische Spannung zwischen Anerkennung und Autonomie ins Auge gefasst. Es folgen schließlich theologische Überlegungen, die an Illouz‘ eigene Ausführungen zur religiösen Dimension der Liebe anknüpfen. (shrink)

In this reply, I show that his attempt to address the challenge (...) does not succeed. (shrink)
