In this article, we report on eight grand challenges for value sensitive design, which were developed at a one-week workshop, Value Sensitive Design: Charting the Next Decade, Lorentz Center, Leiden, The Netherlands, November 14–18, 2016. A grand challenge is a substantial problem, opportunity, or question that motives sustained research and design activity. The eight grand challenges are: Accounting for Power, Evaluating Value Sensitive Design, Framing and Prioritizing Values, Professional and Industry Appropriation, Tech policy, Values and Human Emotions, Value Sensitive Design (...) and Intelligent Algorithms, and Value Tensions. Each grand challenge consists of a discussion of its importance and a set of tractable key questions. (shrink)

In this article, we introduce the Special Issue, Value Sensitive Design: Charting the Next Decade, which arose from a week-long workshop hosted by Lorentz Center, Leiden, The Netherlands, November 14–18, 2016. Forty-one researchers and designers, ranging in seniority from doctoral students to full professors, from Australia, Europe, and North America, and representing a wide range of academic fields participated in the workshop. The first article in the special issue puts forward eight grand challenges for value sensitive design to help guide (...) and shape the field. It is followed by 16 articles consisting of value sensitive design nuggets—short pieces of writing on a new idea, method, challenge, application, or other concept that engages some aspect of value sensitive design. The nuggets are grouped into three clusters: theory, method, and applications. Taken together the grand challenges and nuggets point the way forward for value sensitive design into the next decade and beyond. (shrink)

Drucilla Cornell engaged in scholarship and activism in South Africa for over a decade, and indeed she moved home from New York to Cape Town to participate more fully in the life and politics of the newly democratic country. This was not only a prolific period of scholarship and activism in her life, but also an inflection point in the country’s nascent constitutional jurisprudence. In this article, we memorialize Drucilla’s extraordinary contributions to the development of South Africa’s constitutional order and (...) of its legal academy. We situate these contributions in the broader set of concerns—about dignity and freedom, socialism and democracy, non-Western ideals, feminism, modernity, and the constitution of community—with which she had been engaged since the earliest days of her career. We include relevant anecdotes from her life in South Africa; not only her life as a scholar but also as a teacher, mentor, friend, and above all, a revolutionary activist. (shrink)

Peter Abelard (1079–1142 ce) was the most wide‐ranging philosopher of the twelfth century. He quickly established himself as a leading teacher of logic in and near Paris shortly after 1100. After his affair with Heloise, and his subsequent castration, Abelard became a monk, but he returned to teaching in the Paris schools until 1140, when his work was condemned by a Church Council at Sens. His logical writings were based around discussion of the “Old Logic”: Porphyry's Isagoge, aristotle'S Categories and (...) On Interpretation and boethius'S textbook on topical inference. They comprise a freestanding Dialectica (“Logic”; probably c.1116), a set of commentaries (known as the Logica [Ingredientibus], c. 1119) and a later (c. 1125) commentary on the Isagoge (Logica Nostrorum Petititoni Sociorum or Glossulae). In a work Abelard called his Theologia, issued in three main versions (between 1120 and c.1134), he attempted a logical analysis of trinitarian relations and explored the philosophical problems surrounding God's claims to omnipotence and omniscience. The Collationes (“Debates,” also known as “Dialogue between a Christian, a Philosopher and a Jew”; probably c.1130) present a rational investigation into the nature of the highest good, in which the Christian and the Philosopher (who seems to be modeled on a philosopher of pagan antiquity) are remarkably in agreement. The unfinished Scito teipsum (“Know thyself,” also known as the “Ethics”; c.1138) analyses moral action. (shrink)

This paper examines two cosmological models of quantum gravity to investigate the foundational and conceptual issues arising from quantum treatments of the big bang. While the classical singularity is erased, the quantum evolution that replaces it may not correspond to classical spacetime: it may instead be a non-spatiotemporal region, which somehow transitions to a spatiotemporal state. The different kinds of transition involved are partially characterized, the concept of a physical transition without time is investigated, and the problem of empirical incoherence (...) for regions without spacetime is discussed.

I probe the judgments of the agreeable that we make about food and drink. I first separate different concerns that we might have with food and drink. After that, I address expressive language by first sketching an evolutionary language-game-theoretic approach for referential language. I then try to extend it to expressive language, showing how expressive signaling might be likely to evolve. Given an account of expressive prediction, and its point, I turn to the Frege-Geach problem for the agreeable. I show (...) how a proper understanding of what expression is, in the evolutionary language-game-theoretic framework, allows us to side-step a central aspect the problem. (shrink)

Most of the debate for and against aesthetic formalism in the twentieth century has been little more than a sequence of assertions, on both sides. But there is one discussion that stands out for its argumentative subtlety and depth, and that is Kendall Walton’s paper ‘Categories of Art’.1 In what follows I shall defend a certain version of formalism against the antiformalist arguments which Walton deploys. I want to show that while Walton’s arguments do indeed create insurmountable difficulties for an (...) extreme version of formalism, he has not shown that a moderate version is problematic or inadequate. (I have no space to address anti-formalist arguments other than Walton’s.2) I shall defend moderate formalism rather than put forward positive considerations in its favour, although some of its attractions will become apparent as a side-effect. I pursue the positive case for moderate formalism elsewhere.3 I. FORMAL PROPERTIES AND FORMALISMS I.1. Walton begins his paper by raising an issue about whether those who make aesthetic judgements should only be concerned with what can be directly perceived in works of art. The issue of formalism has often been described in these terms. But Walton rightly distances himself from setting up a debate in that way. He moves on to take as his target the view that ‘Circumstances connected with a work’s origin ... have no essential bearing on an assessment of its aesthetic nature’ (p. 334). (shrink)

I defend extreme formalism about the aesthetics of inorganic nature. I outline the general issue over aesthetic formalism as it manifests itself in the visual arts. The main issue is over whether we need to know about the history of artworks in order to appreciate them aesthetically. I then turn to nature and concede that with organic nature we need to know a thing's biological kinds if we are fully to appreciate it. However, with in organic nature I deny that (...) we need to know the deeper nature of the things we experience. What is important, I argue, are the appearances of those things not their real natures. I consider the beauty of clouds, which depends on an illusion of solidity, and I argue that scientific knowledge does not reveal beauty that is not available to the ignoramous. There is only the beauty of appearances, and it does not matter whether those appearances are accurate or illusory. (shrink)

This paper examines the impact of neoreactionary (NRx) thinking – that of Curtis Yarvin, Nick Land, Peter Thiel and Patri Friedman in particular – on contemporary political debates manifest in ‘architectures of exit’. We specifically focus on Urbit, as an NRx digital architecture that captures how post-neoliberal politics imagines notions of freedom and sovereignty through a micro-fracturing of nation-states into ‘gov-corps’. We trace the development of NRx philosophy – and situate this within contemporary political and technological change to (...) theorize the significance of exit manifest within the notion of ‘dynamic geographies’. While technological programmes such as Urbit may never ultimately succeed, we argue that these, and other speculative investments such as ‘seasteading’, reflect broader post-neoliberal NRx imaginaries that were, perhaps, prefigured a quarter of a century ago in The Sovereign Individual.

Recently it has been increasingly popular to argue that knowledge is the norm of belief. I present an argument against this view. The argument trades on the epistemic situation of the subject in the bad case. Notably, unlike with other superficially similar arguments against knowledge norms, knowledge normers preferred strategy of appealing to the distinction between permissibility and excusability cannot help them to rebut this argument.

Addressing a wide range of topics, from Newton to Post-Kuhnian philosophy of science, these essays critically examine themes that have been central to the influential work of philosopher Michael Friedman.

This paper considers three arguments by David Shugarman and Maureen Ramsay for why dirty hands cannot be democratic. The first argues that it is contradictory, in principle, to use undemocratic means to pursue democratic ends. There is a conceptual connection between means and ends such that getting one’s hands dirty is incompatible with acting in accordance with democratic ends. The second claims that using dirty-handed means, in practice, will undermine democracy more than it promotes it and therefore cannot be justified. (...) The final criticism states that politicians with dirty hands are a sign that politics is no longer meeting the criteria necessary to be called democratic. The paper shows that such rejections of democratic dirty hands are based on misunderstandings of the nature of dirty hands and democratic politics. (shrink)

Three experiments investigated the contrasting predictions of the evolutionary and decision-theoretic approaches to deontic reasoning. Two experiments embedded a hazard management (HM) rule in a social contract scenario that should lead to competition between innate modules. A 3rd experiment used a pure HM task. Threatening material was also introduced into the antecedent, p, of a deontic rule, if p then must q. According to the evolutionary approach, more HM responses (Cosmides & Tooby, 2000) are predicted when p is threatening, whereas (...) decision theory predicts fewer. All 3 experiments were consistent with decision theory. Other theories are discussed, and it is concluded that they cannot account for the behavior observed in these experiments. (shrink)

his paper explores the relationship between Kant’s views on the metaphysical foundations of Newtonian mathematical physics and his more general transcendental philosophy articulated in the Critique of pure reason. I argue that the relationship between the two positions is very close indeed and, in particular, that taking this relationship seriously can shed new light on the structure of the transcendental deduction of the categories as expounded in the second edition of the Critique.Author Keywords: Kant; Mathematical physics; Transcendental deduction.

Sandplay is one of the fastest growing therapies. What are its origins, who were it pioneers, and how have they influenced the current practice of sandplay? What does the future hold? Rie Rogers Mitchell and Harriet S. Friedman have written a unique book that answers all these questions and many more. They give an overview of the historical origins of sandplay, including biographical profiles of the innovators together with discussions of their seminal writings. The five main therapeutic trends are (...) explored, and in a final chapter the future of sandplay is discussed through addressing emerging issues and concerns. A special feature is a comprehensive international bibliography as well as a listing of sandtray videotapes and audiotapes. (shrink)

I defend the view that strong psychophysical superveniences is necessary and sufficient to explain the causal efficacy of mental properties. I employ factual and counterfactual conditionals as defeasible criteria of causal efficacy. And I also deal with certain problems arising from disjunctive and conjunctive properties.

In his paper "Supervenience Revisisted", Simon Blackburn redeployed his novel modal argument against moral realism as an argument against Donald Davidson's position of 'anomalous monism' in the philosophy of mind (Blackburn 1985).' I shall assess this redeployment. In the first part of this paper, I shall lay out Blackburn's argument. In the second and longer part I shall examine Davidson's denial of psychophysical laws in the light of this argument.

I defend the view that morality depends on God against the Euthyphro dilemma by arguing that the reasons that God has for determining the moral-natural dependencies might be personal reasons that have non-moral content. I deflect the 'arbitrary whim' worry, but I concede that the account cannot extend to the goodness of God and His will. However, human moral-natural dependencies can be explained by God's will. So a slightly restricted version of divine commandment theory is defensible.

I develop a theory of social virtue around the concept of a "social opening" and argue that a range of contemporary terms track various modes of success and failure with respect to social openings: ‘awesome’, ‘down’, ‘chill’, ‘sucks’, ‘wack’, ‘lame’, ‘douchebag’, and others. A basic idea is that the normative character of contemporary social life cannot be fully understood in traditional philosophical terms: ‘obligation’, ‘demand’, ‘duty’, ‘right’, ‘just’, ‘requirement’. ‘Sucks’ and ‘awesome’ (and their ilk) capture a special mode of interpersonal (...) critique. Old modes of critique fall short because contemporary social life embodies a concern for cultivating, expressing, and appreciating individuality. This is partly an aesthetic affair, which flavors the modes of response and critique that constitute the normative framework. I detail how our interest in the "ethics of awesomeness" has influenced a range of post-’60s cultural practices, including art, charity, athletics, public life, and others. (shrink)

I exist. That is something I know. Most philosophers think that Descartes was right that each of us knows that we exist. Furthermore most philosophers agree with Descartes that there is something special about how we know it. Agreement ends there. There is little agreement about exactly what is special about this knowledge. I shall present an account that is in some respects Cartesian in spirit, although I shall not pursue interpretive questions very far. On this account, I know that (...) I exist a priori; and I shall advance an explanation of how this a priori knowledge is possible and actual. I then consider the question of whether the belief that I exist is justified and, if so, how. I argue that the situation is different in important ways from the knowledge that I exist. (shrink)

This paper investigates the mathematical representation of time in physics. In existing theories time is represented by the real numbers, hence their formal proper- ties represent properties of time: these are surveyed. The central question of the paper is whether the existing representation of time is adequate, or whether it can or should be supplemented: especially, do we need a physics incorporating some kind of ‘dynamical passage’ of time? The paper argues that the existing mathematical framework is resistant to such (...) changes, and might have to be rejected by anyone seeking a physics of passage. Then it rebuts two common arguments for incorporating passage into physics, especially the claim that it is an element of experience. Finally the paper investigates whether, as has been claimed, ‘causal set theory’ provides a physics of passage. (shrink)

Through hearing we learn about source events: events in which objects move or interact so that they vibrate and produce sound waves, such as when they roll, collide, or scrape together. It is often claimed that we do not simply hear sounds and infer what event caused them, but hear source events themselves, through hearing sounds. Here I investigate how the idea that we hear source events should be understood, with a focus on how hearing an event relates to hearing (...) the objects involved in that event. I argue that whereas we see events such as rollings and collisions by seeing objects move through space, this cannot be how we hear them, and go on to examine two other possible models. On the first, we hear events but not their participant objects. On the second, to hear an event is to hear the appearance of an object to change. I argue that neither is satisfactory and endorse a third option: to hear a source event is to hear an object as extending through time. (shrink)

“Sentential reflection” in the sense of [Fr03] is based on reflecting down from a category of classes. “Elemental sentential reflection” is based on reflecting down from a category of elemental classes. We present various forms of elemental sentential reflection, which are shown to interpret and be interpretable in certain set theories with large cardinal axioms.

We present two forms of “sentential reflection”, which are shown to be mutually interpretable with Z2 and ZFC, respectively.

Gödel's legacy is still very much in evidence. We will not attempt to properly discuss the full impact of his work and all of the ongoing important research programs that it suggests. This would require a book length manuscript. Indeed, there are several books discussing the Gödel legacy from many points of view, including, for example, (Wang 1987, 1996), (Dawson 2005), and the historically comprehensive five volume set (Gödel 1986-2003).

In 1995 Visser, van Benthem, de Jongh, and Renardel de Lavalette introduced NNIL-formulas, showing that these are exactly the formulas preserved under taking submodels of Kripke models. In this article we show that NNIL-formulas are up to frame equivalence the formulas preserved under taking subframes of frames, that NNIL-formulas are subframe formulas, and that subframe logics can be axiomatized by NNIL-formulas. We also define a new syntactic class of ONNILLI-formulas. We show that these are the formulas preserved in monotonic images (...) of frames and that ONNILLI-formulas are stable formulas as introduced by Bezhanishvili and Bezhanishvili in 2013. Thus, ONNILLI is a syntactically defined set of formulas axiomatizing all stable logics. This resolves a problem left open in 2013. (shrink)

Erich Fromm was a political activist, psychologist, psychoanalyst, philosopher, and one of the most important intellectuals of the twentieth century. Known for his theories of personality and political insight, Fromm dissected the sadomasochistic appeal of brutal dictators while also eloquently championing love--which, he insisted, was nothing if it did not involve joyful contact with others and humanity at large. Admired all over the world, Fromm continues to inspire with his message of universal brotherhood and quest for lasting peace. The first (...) systematic study of Fromm's influences and achievements, this biography revisits the thinker's most important works, especially _Escape from Freedom_ and _The Art of Loving_, which conveyed important and complex ideas to millions of readers. The volume recounts Fromm's political activism as a founder and major funder of Amnesty International, the National Committee for a Sane Nuclear Policy, and other peace groups. Consulting rare archival materials across the globe, Lawrence J. Friedman reveals Fromm's support for anti-Stalinist democratic movements in Central and Eastern Europe and his efforts to revitalize American democracy. For the first time, readers learn about Fromm's direct contact with high officials in the American government on matters of war and peace while accessing a deeper understanding of his conceptual differences with Freud, his rapport with Neo-Freudians like Karen Horney and Harry Stack Sullivan, and his association with innovative artists, public intellectuals, and world leaders. Friedman elucidates Fromm's key intellectual contributions, especially his innovative concept of "social character," in which social institutions and practices shape the inner psyche, and he clarifies Fromm's conception of love as an acquired skill. Taking full stock of the thinker's historical and global accomplishments, Friedman portrays a man of immense authenticity and spirituality who made life in the twentieth century more humane than it might have been.
