We construct an existentially undecidable complete discretely valued field of mixed characteristic with existentially decidable residue field and decidable algebraic part, answering a question by Anscombe–Fehm in a strong way. Along the way, we construct an existentially decidable field of positive characteristic with an existentially undecidable finite extension, modifying a construction due to Kesavan Thanagopal.

We introduce and study a natural class of fields in which certain first-order definable sets are existentially definable, and characterise this class by a number of equivalent conditions. We show that global fields belong to this class, and in particular obtain a number of new existential predicates over global fields.

We study when the property that a field is dense in its real and p-adic closures is elementary in the language of rings and deduce that all models of the theory of algebraic fields have this property.

Husserlian phenomenology, as the study of conscious experience, has often been accused of solipsism. Husserl’s method, it is argued, does not have the resources to provide an account of consciousness of other minds. This chapter will address this issue by providing a brief overview of the multiple angles from which Husserl approached the theme of intersubjectivity, with specific focus on the details of his account of the concrete interpersonal encounter – “empathy.” Husserl understood empathy as a direct, quasi-perceptual form of (...) intentionality through which the sense of the Other is constituted. Furthermore, his account of empathy is holistically integrated with his overall theory of intersubjectivity, including his discussions of the objectivity of nature, and the social, historical, and communal aspects of subjectivity. Husserl’s theory of empathy continues to cast a long shadow, influencing both the analytic and continental approaches to the problem of other minds, as well as contemporary account of social cognition in the cognitive sciences.

This article draws on the antebellum political thought of Black abolitionists Frederick Douglass and Martin Delany in critically assessing the efficacy of reasonableness in advancing the aims of emancipatory politics in political discourse. I argue, through a reading of Douglass and Delany, that comporting oneself reasonably in the face of oppressive ideology can be counterproductive, if one’s aim is to undermine such ideology and the institutions it supports. Douglass and Delany, I argue, also provide us with a framework for evaluating (...) alternative discursive strategies we might wish to employ in light of the limited value of reasonableness for emancipatory politics.

For liberal contractarians, moral and political principles are justified if agreeable to persons as free and equals. But for critics of liberal contractarianism, this justification applies only to those capable of agreement. Understanding why contractarianism suffers from the problem of exclusion helps up understand the distinctive character of contractarianism and the importance of agreement in particular. I suggest contractarianism need not be objectionably exclusive. I first consider why agreement is important in contractarianism, and then introduce the main versions of contemporary (...) contractarianism and their different understandings of agreement. I discuss how agreement results in exclusion in each, and distinguish two kinds of response to the problem of exclusion: differential inclusion and permissive inclusion. Differential inclusion is unsuccessful because it offers those not fully capable of agreement unequal status. Permissive inclusion may either make the circumstances of agreement more open, or characterize the capacities required for inclusion more permissively. I advocate the latter as the most promising response to the problem of exclusion. I outline a more inclusive contractualism based on the capacity to share goals. (shrink)

The _Platform Sutra_ records the teachings of Hui-neng, the Sixth Patriarch, who is revered as one of the two great figures in the founding of Ch'an (Zen) Buddhism. This translation is the definitive English version of the eighth-century Ch'an classic. Phillip B. Yampolsky has based his translation on the Tun-huang manuscript, the earliest extant version of the work. A critical edition of the Chinese text is given at the end of the volume. Dr. Yampolsky also furnishes a lengthy and detailed (...) historical introduction which contains much information hitherto unavailable even to scholars, and provides the context essential to an understanding of Hui-neng's work. He gives an account of the history and legends of Ch'an Buddhism, with particular attention to the traditions associated with Hui-neng, quoting or summarizing the most important narratives. He then discusses the various texts of the _Platform Sutra_, and analyzes its contents. (shrink)

ABSTRACT Constitutive panpsychism is the doctrine that macro-level consciousness—that is, consciousness of the sort possessed by certain composite things such as humans—is built out of irreducibly mental features had by some or all of the basic physical constituents of reality. On constitutive panpsychism, changes in macro-level consciousness amount to changes in either the way that micro-conscious entities ‘bond’ or the way that micro-conscious qualities ‘blend’. I pose the ‘Selection Problem’ for constitutive panpsychism—the problem of explaining how high-level functional states of (...) the brain ‘select’ micro-conscious qualities for bonding or blending. I argue that there are no empirically plausible solutions to this problem. (shrink)

It is intuitive that free action depends on consciousness in some way, since behavior that is unconsciously generated is widely regarded as un-free. But there is no clear consensus as to what such dependence comes to, in part because there is no clear consensus about either the cognitive role of consciousness or about the essential components of free action. I divide the space of possible views into four: the Constitution View (on which free actions metaphysically consist, at least in part, (...) in phenomenally conscious episodes of a special sort), the Causal-Dependence View (on which free actions are necessarily caused by conscious episodes), the Counterfactaul-Dependence View (on which free actions necessarily counterfactually dependent on conscious episodes of certain types), and the Independence View (on which there are no necessary dependence-relations that hold between free action and conscious episodes). After surveying recent empirical literature that purports to show that consciousness plays a smaller role in generating action than is usually supposed, I conclude that it is plausible that free action depends on consciousness in two ways. First, free action causally depends on consciousness control. Second, free action counterfactually depends on the agent's being responsive to certain reasons. (shrink)

I discuss three tiers of technological innovation: mild innovation, or the acceleration by technology of a human activity aimed at a good; moderate innovation, or the obviation by technology of an activity aimed at a good; and radical innovation, or the altering by technology of the human condition so as to change what counts as a good. I argue that it is impossible to morally assess proposed innovations within any of these three tiers unless we rehabilitate a natural-law ethical framework. (...) And I offer some moral starting points within such a framework, in connection with innovations of each of the three types. (shrink)

Breaking off the ordinary flow of experience, the passions create a state of exception. In their suddenness and intensity, they map a personal world, fix and qualify our attention, and impel our actions. Outraged anger drives us to write laws that will later be enforced by impersonal justice. Intense grief at the death of someone in our life discloses the contours of that life to us. Wonder spurs scientific inquiry. The strong current of Western thought that idealizes a dispassionate world (...) has ostracized the passions as quaint, even dangerous. Intense states have come to be seen as symptoms of pathology. A fondness for irony along with our civic ideal of tolerance lead us to prefer the diluted emotional life of feelings and moods. Demonstrating enormous intellectual originality and generosity, Philip Fisher meditates on whether this victory is permanent-and how it might diminish us. From Aristotle to Hume to contemporary biology, Fisher finds evidence that the passions have defined a core of human nature no less important than reason or desire. Traversing the Iliad, King Lear, Moby Dick, and other great works, he discerns the properties of the high-spirited states we call the passions. Are vehement states compatible with a culture that values private, selectively shared experiences? How do passions differ from emotions? Does anger have an opposite? Do the passions give scale, shape, and significance to our experience of time? Is a person incapable of anger more dangerous than someone who is irascible? In reintroducing us to our own vehemence, Fisher reminds us that it is only through our strongest passions that we feel the contours of injustice, mortality, loss, and knowledge. It is only through our personal worlds that we can know the world. (shrink)

Im ersten Drittel des 20. Jahrhunderts ubte Henri Bergson insbesondere in Frankreich grossen Einfluss auf Philosophie, Wissenschaft und Literatur aus. Auch Henri Matisse, der den Philosophen zwar nie personlich traf, kannte dessen Gedankengut. Bereits 1908 tauchen in denSchriften Matisse' Formulierungen wie Tiefe des Gedankens, Verdichtung der Empfindungen, wesentlicher Charakter, dauerhaftere Interpretation auf, die allein durch die Philosophie Bergsons umfassend erlautert und begrundet werden konnen.Bei beiden sind Aspekte wie Intuition, Instinkt, Identifikation, Dauer, Entwicklung, Leben, Schopfung zentrale Gesichtspunkte. In der kunstgeschichtlichen Literatur (...) zu Matisse wurde zwar mehrfach auf den Bezug zu Bergson verwiesen, nun liegt jedoch erstmals eine eingehende Untersuchung dieser geistigen Begegnung vor. Der Autor stellt die zentralen Schriften Bergsons in ihren Grundzugen dar und akzentuiert die Gedanken, die mit Texten und Bildern von Matisse korrespondieren. Daneben eroffnet er weit reichende Einblicke in die kunstlerische und malerische Dimension des Werkes von Matisse. (shrink)

Husserl introduces a phenomenological concept called “motivation” early in the First Investigation of his magnum opus, the Logical Investigations. The importance of this concept has been overlooked since Husserl passes over it rather quickly on his way to an analysis of the meaningful nature of expression. I argue, however, that motivation is essential to Husserl’s overall project, even if it is not essen- tial for defining expression in the First Investigation. For Husserl, motivation is a relation between mental acts whereby (...) the content of one act make some fur- ther meaningful content probable. I explicate the nature of this relation in terms of “evidentiary weight” and differentiate it from Husserl’s notion of Evidenz, often translated as “self-evidence”. I elucidate the importance of motivation in Husserl’s overall phenomenological project by focusing on his analyses of thing-perception and empathy. Through these examples, we can better understand the continuity between the Logical Investigations and Husserl’s later work. (shrink)

Based on his military work, Wiener developed a general mathematical theory of control and feedback system. We discuss the origins of control and feedback theory in Germany , showing that it arose in a very different context.Hermann Schmidt , the principal actor in Germany, though trained as a physicist, formulated his version of control theory based on his extensive hands-on experience with control mechanisms gained during his work as a patent officer in the late 1930s at the German State Patent Office.

Arendt Contra Sociology re-assesses the relationship between Hannah Arendt's work and the theoretical foundations of sociology, bringing her insights to bear on key themes within contemporary theoretical sociology. Departing from the view of Arendt as a political theorist who sought to rescue politics from society, and political theory from the social sciences, this book re-examines her distinctions between labour, fabrication and action as a theory of the fundamental ontology of human societies, revisiting her criticism of the tendency of many sociological (...) paradigms to conflate the activity of fabrication with that of action.

In late March of 2020, a new hashtag, #FilmYourHospital, made its first appearance on social media. The hashtag encouraged people to visit local hospitals to take pictures and videos of empty hospitals to help “prove” that the COVID-19 pandemic is an elaborate hoax. Using techniques from Social Network Analysis, this case study examines how this conspiracy theory propagated on Twitter and whether the hashtag virality was aided by the use of automation or coordination among Twitter users. We found that while (...) much of the content came from users with limited reach, the oxygen that fueled this conspiracy in its early days came from a handful of prominent conservative politicians and far right political activists on Twitter. These power users used this hashtag to build awareness about the campaign and to encourage their followers to break quarantine and film what is happening at their local hospitals. After the initial boost by a few prominent accounts, the campaign was mostly sustained by pro-Trump accounts, followed by a secondary wave of propagation outside the U.S. The rise of the #FilmYourHospital conspiracy from a single tweet demonstrates the ongoing challenge of addressing false, viral information during the COVID-19 pandemic. While the spread of misinformation can be potentially mitigated by fact-checking and directing people to credible sources of information from public health agencies, false and misleading claims that are driven by politics and supported by strong convictions and not science are much harder to root out.

The notion of risk plays a central role in economics, finance, health, psychology, law and elsewhere, and is prevalent in managing challenges and resources in day-to-day life. In recent work, Duncan Pritchard (2015, 2016) has argued against the orthodox probabilistic conception of risk on which the risk of a hypothetical scenario is determined by how probable it is, and in favour of a modal conception on which the risk of a hypothetical scenario is determined by how modally close it is. (...) In this article, we use Pritchard’s discussion as a springboard for a more wide-ranging discussion of the notion of risk. We introduce three different conceptions of risk: the standard probabilistic conception, Pritchard’s modal conception, and a normalcy conception that is new (though it has some precursors in the psychological literature on risk perception). Ultimately, we argue that the modal conception is ill-suited to the roles that a notion of risk is required to play and explore the prospects for a form of pluralism about risk, embracing both the probabilistic and the normalcy conceptions.

This is the first complete English translation of Gottlob Frege's Grundgesetze der Arithmetik, with introduction and annotation. The importance of Frege's ideas within contemporary philosophy would be hard to exaggerate. He was, to all intents and purposes, the inventor of mathematical logic, and the influence exerted on modern philosophy of language and logic, and indeed on general epistemology, by the philosophical framework.

The paper asks: are all tautologies true in a language with truth-value gaps? It answers that they are not. No tautology is false, of course, but not all are true. It also contends that not all contradictions are false in a language with truth-value gaps, though none are true.

This paper develops a philosophical account of moral disruption. According to Robert Baker, moral disruption is a process in which technological innovations undermine established moral norms without clearly leading to a new set of norms. Here I analyze this process in terms of moral uncertainty, formulating a philosophical account with two variants. On the harm account, such uncertainty is always harmful because it blocks our knowledge of our own and others’ moral obligations. On the qualified harm account, there is no (...) harm in cases where moral uncertainty is related to innovation that is “for the best” in historical perspective or where uncertainty is the expression of a deliberative virtue. The two accounts are compared by applying them to Baker’s historical case of the introduction of mechanical ventilation and organ transplantation technologies, as well as the present-day case of mass data practices in the health domain.
