A new axiom is proposed, the Ground Axiom, asserting that the universe is not a nontrivial set forcing extension of any inner model. The Ground Axiom is first-order expressible, and any model of ZFC has a class forcing extension which satisfies it. The Ground Axiom is independent of many well-known set-theoretic assertions including the Generalized Continuum Hypothesis, the assertion V=HOD that every set is ordinal definable, and the existence of measurable and supercompact cardinals. The related Bedrock Axiom, asserting that the (...) universe is a set forcing extension of a model satisfying the Ground Axiom, is also first-order expressible, and its negation is consistent.

We present a class forcing notion, uniformly definable for ordinals η, which forces the ground model to be the ηth inner mantle of the extension, in which the sequence of inner mantles has length at least η. This answers a conjecture of Fuchs, Hamkins, and Reitz [1] in the positive. We also show that forces the ground model to be the ηth iterated of the extension, where the sequence of iterated s has length at least η. We conclude by (...) showing that the lengths of the sequences of inner mantles and of iterated s can be separated to be any two ordinals you please. (shrink)

Given an inner model and a regular cardinal κ, we consider two alternatives for adding a subset to κ by forcing: the Cohen poset Add(κ, 1), and the Cohen poset of the inner model. The forcing from W will be at least as strong as the forcing from V (in the sense that forcing with the former adds a generic for the latter) if and only if the two posets have the same cardinality. On the other hand, a sufficient condition (...) is established for the poset from V to fail to be as strong as that from W. The results are generalized to, and to iterations of Cohen forcing where the poset at each stage comes from an arbitrary intermediate inner model. (shrink)

A pointwise definable model is one in which every object is \loos definable without parameters. In a model of set theory, this property strengthens $V=\HOD$, but is not first-order expressible. Nevertheless, if \ZFC\ is consistent, then there are continuum many pointwise definable models of \ZFC. If there is a transitive model of \ZFC, then there are continuum many pointwise definable transitive models of \ZFC. What is more, every countable model of \ZFC\ has a class forcing extension that is pointwise definable. (...) Indeed, for the main contribution of this article, every countable model of Gödel-Bernays set theory has a pointwise definable extension, in which every set and class is first-order definable without parameters.

We introduce and consider the inner-model reflection principle, which asserts that whenever a statement \varphi(a) in the first-order language of set theory is true in the set-theoretic universe V, then it is also true in a proper inner model W \subset A. A stronger principle, the ground-model reflection principle, asserts that any such \varphi(a) true in V is also true in some non-trivial ground model of the universe with respect to set forcing. These principles each express a form of width (...) reflection in contrast to the usual height reflection of the Lévy–Montague reflection theorem. They are each equiconsistent with ZFC and indeed \Pi_2-conservative over ZFC, being forceable by class forcing while preserving any desired rank-initial segment of the universe. Furthermore, the inner-model reflection principle is a consequence of the existence of sufficient large cardinals, and lightface formulations of the reflection principles follow from the maximality principle MP and from the inner-model hypothesis IMH. We also consider some questions concerning the expressibility of the principles. (shrink)

Meet the Metaorganism is a web‐based learning app that combines three fundamental biological concepts (coevolution, community dynamics, and immune system) with latest scientific findings using the metaorganism as a central case study. In a transdisciplinary team of scientists, information designers, programmers, science communicators, and educators, we conceptualized and developed the app according to the latest didactic and scientific findings and aimed at setting new standards in visual design, digital knowledge transfer, and online education. A content management system allows continuous integration (...) of new findings, which enables us to expand the app with the dynamics of the research field. Students can thus gain a close insight and connection to current research, and at the same time learn that knowledge is not static but grows dynamically. Especially in the realm of the easily accessible metaorganism research, visualization plays an essential role to keep complex processes understandable and memorable. Meet the Metaorganism is freely available online and can be accessed here: www.metaorganism.app. (shrink)

Can art, religion, or philosophy afford ineffable insights? If so, what are they? The idea of ineffability has puzzled philosophers from Laozi to Wittgenstein. In Ineffability and its Metaphysics: The Unspeakable in Art, Religion and Philosophy, Silvia Jonas examines different ways of thinking about what ineffable insights might involve metaphysically, and shows which of these are in fact incoherent. Jonas discusses the concepts of ineffable properties and objects, ineffable propositions, ineffable content, and ineffable knowledge, examining the metaphysical pitfalls (...) involved in these concepts. Ultimately, she defends the idea that ineffable insights as found in aesthetic, religious, and philosophical contexts are best understood in terms of self-acquaintance, a particular kind of non-propositional knowledge. Ineffability as a philosophical topic is as old as the history of philosophy itself, but contributions to the exploration of ineffability have been sparse. The theory developed by Jonas makes the concept tangible and usable in many different philosophical contexts. (shrink)

​In Abwandlung eines Satzes von Luhmann ließe sich über Gesellschaften der Gegenwart sagen: Fast alles könnte anders sein, und fast nichts können wir kollektiv ändern. Wie rasch sich umweltschädliche Technologien auf dem Globus ausbreiten, welche Unternehmen und welche Ausbeutungsformen erfolgreich sind, welche Ungleichheiten trotz formeller Gleichheit reproduziert werden, entzieht sich großenteils staatlichen und erst recht demokratisch legitimierten Entscheidungen. Stattdessen scheinen unkontrollierbare gesellschaftliche Wechselwirkungen, namentlich die des krisenhaften Weltmarkts bestimmend zu sein. Das stellt offenkundig eine Herausforderung für die politische Theorie dar. (...) Eine wichtige Antwort besteht darin, dass sie vermehrt jenseits der Zentren ansetzt, die offiziell für Entscheidungen zuständig sind, und sich dezentralen Auseinandersetzungen zuwendet. Zugleich sollte sie jedoch genauer als bisher der Annahme nachgehen, dass die Grenzen und Grundstrukturen des kollektiv nicht Gestaltbaren selbst keineswegs klar sind und (proto-)politisch umkämpft bleiben​.

My aim in this essay is largely defensive. I aim to discuss some problems for moral error theory and to offer plausible solutions. A full positive defense of moral error theory would require substantial investigations of rival metaethical views, but that is beyond the scope of this essay. I will, however, try to motivate moral error theory and to clarify its commitments. Moral error theorists typically accept two claims – one conceptual and one ontological – about moral facts. The conceptual (...) claim is that moral facts are or entail facts about categorical reasons (and correspondingly that moral claims are or entail claims about categorical reasons); the ontological claim is that there are no categorical reasons – and consequently no moral facts – in reality. I accept this version of moral error theory and I try to unpack what it amounts to in Section 2.1 In the course of doing so I consider two preliminary objections: that moral error theory is (probably) false because its implications are intuitively unacceptable (what I call the Moorean objection) and that the general motivation for moral error theory is self-undermining in that it rests on a hidden appeal to norms. The above characterization seems to entail the standard formulation of moral error theory, according to which first-order moral claims are uniformly false. Critics have argued that the standard formulation is incoherent since – by the law of excluded middle – the negation of a false claim is true. Hence if ‘Torture is wrong’ is false, ‘Torture is not wrong’ is true. Contrary to what moral error theorists contend, then, moral error theory seems to carry first-order moral implications that by the theory’s own lights are uniformly false. In Section 3 I suggest a formulation that is consistent with the standard formulation of moral error theory, free of first-order moral implications, and subject to no logical difficulties. In Section 4 I consider and rebut Stephen Finlay’s recent attack on moral error theory. According to Finlay the conceptual claim is false because all moral claims – and indeed all normative claims – are, or should be understood as, relativized to some moral standard or system of ends. Moral error theorists thus attribute to ordinary speakers an error that simply isn’t there. I argue that Finlay’s view has some very implausible implications and that it does not avoid commitment to various forms of error theory. This becomes especially clear when we focus on fundamental moral claims. In Section 5 I consider the worry that error theorists’ rejection of categorical reasons proves too much; in particular, the worry that error theorists’ qualms about categorical reasons apply equally to claims about hypothetical reasons, that is, claims to the effect that there is reason to take the means to one’s ends. In my view error theorists such as Mackie and Joyce have failed to pay due consideration to this problem. What the challenge establishes, I submit, is that error theorists cannot just take for granted that hypothetical reasons are metaphysically unproblematic; they must offer an account of hypothetical reasons that shows that they are. I argue that the only plausible account available to error theorists is one according to which claims about hypothetical reasons reduce to non-normative claims about relations between means and ends.

Die Demut wird gegenwärtig entweder als ein verstaubtes Erbe des Christentums wahrgenommen oder vermehrt als ein säkulares „Modewort“ verstanden, das als mahnender Aufruf für die Rückgewinnung eines verlorenen Maßes zum Einsatz kommt. Jonas Puchta unternimmt den Versuch, unter Berücksichtigung der christlichen Tradition und ihrer Kritiker die Demut auf Grundlage einschlägiger Erfahrungen des Menschseins auf den Begriff zu bringen.

This chapter focuses exclusively on normative reasons. Normative reasons count in favor of actions and attitudes like beliefs, desires, feelings, and emotions. Section 11.2 explores the common ground concerning the metaphysics of reasons. We shall see that the really controversial metaphysical issues in metanormative theorizing about reasons arise with respect to the metaphysics of the reason relation. The two subsequent sections therefore go beyond the common ground and consider competing accounts of the reason relation. Robust and quietist versions of non-naturalism (...) are considered in section 11.3 and naturalism is considered in section 11.4. Section 11.5 summarizes and gives a brief comparative assessment of the accounts considered. (shrink)

erster Teilband. Grundlegung -- zweiter Teilband. Tragweite und Aktualität einer Zukunftsethik.

Jonas Olson presents a critical survey of moral error theory, the view that there are no moral facts and so all moral claims are false. Part I explores the historical context of the debate; Part II assesses J. L. Mackie's famous arguments; Part III defends error theory against challenges and considers its implications for our moral thinking.

Experiences—visual, emotional, or otherwise—play a role in providing us with justification to believe claims about the world. Some accounts of how experiences provide justification emphasize the role of the experiences’ distinctive phenomenology, i.e. ‘what it is like’ to have the experience. Other accounts emphasize the justificatory role to the experiences’ etiology. A number of authors have used cases of cognitively penetrated visual experience to raise an epistemic challenge for theories of perceptual justification that emphasize the justificatory role of phenomenology rather (...) than etiology. Proponents of the challenge argue that cognitively penetrated visual experiences can fail to provide the usual justification because they have improper etiologies. However, extant arguments for the challenge’s key claims are subject to formidable objections. In this paper, I present the challenge’s key claims, raise objections to previous attempts to establish them, and then offer a novel argument in support of the challenge. My argument relies on an analogy between cognitively penetrated visual and emotional experiences. I argue that some emotional experiences fail to provide the relevant justification because of their improper etiologies and conclude that analogous cognitively penetrated visual experiences fail to provide the relevant justification because of their etiologies, as well.

Critical thinking is considered to be a central epistemic aim of education. The claim may be about skills, but also about the state of justified belief. In opposition to this latter view, Alvin Goldman claimed that justification is only a means to true belief and that the only fundamental epistemic aim of education is true belief. Harvey Siegel’s response defended the view that justified belief is in fact a fundamental epistemic aim of education. In a recent article, Alessia Marabini and (...) Luca Moretti analyse Siegel’s arguments, reject all of them, and provide two new ones. I defend one of Siegel’s arguments against their objection, raise some doubts about one of their own arguments, and give an additional argument against Goldman’s view. (shrink)

This paper revisits Richard Price’s Review of the Principal Questions in Morals. Price was a defender of rationalism about ethics and he anticipated many views and arguments that became influential as the metaethical and ethical debates evolved over the later centuries. The paper explores and assesses Price’s arguments in favour of rationalism and against sentimentalism, with a view to how they bear on the modern metaethical debate.

Error theories have been proposed and defended in several different areas of philosophy. In addition to ethics, there are error theories about numbers, color, free will, and personal identity. Moral error theories differ in scope. Theories at one end of the spectrum take normative judgments in general—of which moral judgments are a subclass—to be uniformly false, whereas theories at the other end of the spectrum take only a subclass of moral judgments—example those concerning duty and obligation, but not those concerning (...) virtue and vice—to be uniformly false. Moral error theorists typically join forces with non-naturalist realists, against naturalism and non-cognitivism. Facts that are normative in the reason-implying sense are irreducibly normative, and they are very different. Many non-naturalist realists and error theorists maintain that it is impossible to give a plausible naturalistic account of moral facts, precisely because they are irreducibly normative; moral naturalism therefore falls prey to the "normativity objection".

Recognizing yourself in literature cannot only help you to get a clearer grasp of what you already think and feel. It can also deeply unsettle your vision of yourself. This article examines a hitherto neglected mechanism to this effect: learning by way of seeing yourself in others’ blindness. I show that In Search of Lost Time epitomizes this phenomenon. Confronting characters oblivious to their old age makes the protagonist realize that he, too, has aged without noticing it, and invites readers (...) to analogous insights. The paper contributes to the discussion on how you can learn from literature and adds a twist to Proust’s claim that the purpose of literature is that readers recognize themselves in it. (shrink)

Moral nihilism is the view that there are no moral facts or moral truths. It is the ontological component of moral error theory, which is the best-known and most comprehensive metaethical theory that involves moral nihilism. My main aim is to discuss some consequences of endorsing moral error theory or believing to some degree that moral error theory is true. In §2, I consider the implications for ordinary moral thought and discourse and the epistemological consequences for moral theorizing. In §3, (...) I consider a recent challenge, according to which moral judgments do not have the epistemic profile that moral error theory alleges. I shall argue in §3–5 that the challenge can be met and that there is evidence that moral error theory is in fact correct about the epistemic profile of moral judgments. (shrink)

The book develops the metaphysics of meaning along the lines set up by Paul Grice, defining the three central notions of what is meant, said and implicated. The Gricean notion of what is said is threatened by semantic underdetermination: If the sentence underdetermines the thought it is used to express, what is said cannot be the proposition expressed by the sentence and meant by the speaker. This leads to a number of questions: How far does semantic underdetermination reach? Do we (...) have to extend or restrict the Gricean notion? Is what is said semantic or pragmatic? Keeping these metaphysical questions separate from the epistemological question of how the hearer understands what is meant, which is best explained by generalizing the Gricean theory of implicature derivation and combining it with a game-theoretic model, the book provides an original defense of a Gricean view in the ongoing debate about semantics and pragmatics.

This paper concerns how extant theorists of predictive coding conceptualize and explain possible instances of cognitive penetration. §I offers brief clarification of the predictive coding framework and relevant mechanisms, and a brief characterization of cognitive penetration and some challenges that come with defining it. §II develops more precise ways that the predictive coding framework can explain, and of course thereby allow for, genuine top-down causal effects on perceptual experience, of the kind discussed in the context of cognitive penetration. §III develops (...) these insights further with an eye towards tracking one extant criterion for cognitive penetration, namely, that the relevant cognitive effects on perception must be sufficiently direct. Throughout these discussions, we extend the analyses of the predictive coding models, as we know them. So one open question that surfaces is how much of the extended analyses are genuinely just part of the predictive coding models, or something that must be added to them in order to generate these additional explanatory benefits. In §IV, we analyze and criticize a claim made by some theorists of predictive coding, namely, that (interesting) instances of cognitive penetration tend to occur in perceptual circumstances involving substantial noise or uncertainty. It is here that our analysis is most critical. We argue that, when applied, the claim fails to explain (or perhaps even be consistent with) a large range of important and uncontroversially interesting possible cases of cognitive penetration. We conclude with a general speculation about how the recent work on the predictive mind may influence the current dialectic concerning top-down effects on perception. (shrink)

The first decade of event-related potential (ERP) research had established that the most consistent correlates of the onset of visual consciousness are the early visual awareness negativity (VAN), a posterior negative component in the N2 time range, and the late positivity (LP), an anterior positive component in the P3 time range. Two earlier extensive reviews ten years ago had concluded that VAN is the earliest and most reliable correlate of visual phenomenal consciousness, whereas LP probably reflects later processes associated with (...) reflective/access consciousness. This article provides an update to those earlier reviews. ERP and MEG studies that have appeared since 2010 and directly compared ERPs between aware and unaware conditions are reviewed, and important new developments in the field are discussed. The result corroborates VAN as the earliest and most consistent signature of visual phenomenal consciousness, and casts further doubt on LP as an ERP correlate of phenomenal consciousness. (shrink)

Is the procreation asymmetry intuitively supported? According to a recent article in this journal, an experimental study suggests the opposite. Dean Spears (2020) claims that nearly three-quarters of participants report that there is a reason to create a person just because that person’s life would be happy. In reply, I argue that various confounding factors render the study internally invalid. More generally, I show how one might come to adopt the procreation asymmetry for the wrong reasons by misinterpreting one’s intuitions.

The main goal of this paper is to work out Quine's account of explication. Quine does not provide a general account, but considers a paradigmatic example which does not fit other examples he claims to be explications. Besides working out Quine's account of explication and explaining this tension, I show how it connects to other notions such as paraphrase and ontological commitment. Furthermore, I relate Quinean explication to Carnap's conception and argue that Quinean explication is much narrower because its main (...) purpose is to be a criterion of theory choice. (shrink)

Clearing up the confusion about religion, re-visioning the core elements of spiritual traditions, and transcending the fault line of secular-versus-religious.

Racial animosities are being mobilized today by right-wing voices in the US media. Resurgent racism requires intelligent analysis and societal intervention. This essay discusses how the classic, five-volume series Studies in Prejudice, undertaken by Max Horkheimer and others in the Frankfurt School, including Herbert Marcuse, furnishes a critical foundation. The mobilization of bias with regard to historical anti-Semitic abuses was seen to depend in definite ways upon an authoritarian type of personality structure. Herbert Marcuse strengthened the analysis by emphasizing that (...) prejudice formation must be understood as well within concrete socioeconomic conflicts and the requirements of repressive political forces.

We will look critically at three essays by Cora Diamond concerning Peter Winch's views on the possibility of communication and criticism between language-games. We briefly present our understanding of Winch's approach to philosophy. Then, we argue that Diamond misidentifies Winch's views, taking them to imply language-game relativism or linguistic idealism. When she does raise valid criticisms against language-game relativism, her critical points mainly coincide with things that Winch has already stressed in his own work. That leaves us with the question (...) what their real disagreement amounts to. Finally, we suggest that at the bottom of Diamond's objections lies her failure to appreciate Winch's insights about the place of logic in human intercourse. (shrink)

A timely addition to Henry Giroux's Critical Interventions series, Ecology and Revolution is grounded in the Frankfurt School critical theory of Herbert Marcuse. Its task is to understand the economic architecture of wealth extraction that undergirds today's intensifying inequalities of class, race, and gender, within a revolutionary ecological frame. Relying on newly discovered texts from the Frankfurt Marcuse Archive, this book builds theory and practice for an alternate world system. Ecology and radical political economy, as critical forms of systems analysis, (...) show that an alternative world system is essential - both possible and feasible - despite political forces against it. Our rights to a commonwealth economy, politics, and culture reside in our commonworks as we express ourselves as artisans of the common good. It is in this context, that Charles Reitz develops a GreenCommonWealth Counter-Offensive, a strategy for revolutionary ecological liberation with core features of racial equality, women's equality, liberation of labor, restoration of nature, leisure, abundance, and peace.
