The Problem of Iterated Ground is to explain what grounds truths about ground: if Γ grounds φ, what grounds that Γ grounds φ? This paper develops a novel solution to this problem. The basic idea is to connect ground to explanatory arguments. By developing a rigorous account of explanatory arguments we can equip operators for factive and non-factive ground with natural introduction and elimination rules. A satisfactory account of iterated ground falls directly out of the resulting logic: non- factive grounding (...) claims, if true, are zero-grounded in the sense of Fine. (shrink)

I discuss three recent counterexamples to the transitivity of grounding due to Jonathan Schaffer. I argue that the counterexamples don’t work and draw some conclusions about the relationship between grounding and explanation.

Most authors on metaphysical grounding have taken full grounding to be an internal relation in the sense that it's necessary that if the grounds and the grounded both obtain, then the grounds ground the grounded. The negative part of this essay exploits empirical and provably nonparadoxical self-reference to prove conclusively that even immediate full grounding isn't an internal relation in this sense. The positive, second part of this essay uses the notion of a “completely satisfactory explanation” to shed light on (...) the logic of ground in the presence of self-reference. This allows us to develop a satisfactory logic of ground and recover a sense in which grounding is still an internal relation. (shrink)

This paper evaluates the proof-theoretic definition of ground developed by Poggiolesi in a range of recent publications and argues that her proposed definition fails. The paper then outlines an alternative approach where logical consequence relations and the logical operations are defined in terms of ground.

I systematically defend a novel account of the grounds for identity and distinctness facts: they are all uniquely zero‐grounded. First, this Null Account is shown to avoid a range of problems facing other accounts: a relation satisfying the Null Account would be an excellent candidate for being the identity relation. Second, a plenitudinist view of relations suggests that there is such a relation. To flesh out this plenitudinist view I sketch a novel framework for expressing real definitions, use this framework (...) to give a definition of identity, and show how the central features of the identity relation can be deduced from this definition.

A logic of grounding where what is grounded can be a collection of truths is a “many-many” logic of ground. The idea that grounding might be irreducibly many-many has recently been suggested by Dasgupta. In this paper I present a range of novel philosophical and logical reasons for being interested in many-many logics of ground. I then show how Fine’s State-Space semantics for the Pure Logic of Ground can be extended to the many-many case, giving rise to the Pure Logic (...) of Many-Many Ground. In the second, more technical, part of the paper, I do two things. First, I present an alternative formalization of plg; this allows us to simplify Fine’s completeness proof for plg. Second, I formalize plmmg using an infinitary sequent calculus and prove that this formalization is sound and complete. (shrink)

Fine (2012) is a pluralist about grounding. He holds that there are three fundamentally distinct notions of grounding: metaphysical, normative, and natural. Berker (2017) argues for monism on the grounds that the pluralist cannot account for certain principles describing how the distinct notions of grounding interact. This paper defends pluralism. By building on work by Fine (2010) and Litland (2015) I show how the pluralist can systematically account for Berker's interaction principles.

Wilhelm has recently shown that widely accepted principles about immediate ground are inconsistent with some principles of propositional identity. This note responds to this inconsistency by developing two ground-theoretic accounts of propositional individuation. On one account some of the grounding principles are incorrect; on the other account, the principles of propositional individuation are incorrect.

Could φ’s partially grounding ψ itself be a partial ground for ψ? I show that it follows from commonly accepted principles in the logic of ground that this sometimes happens. It also follows from commonly accepted principles that this never happens. I show that this inconsistency turns on different principles than the puzzles of ground already discussed in the literature, and I propose a way of resolving the inconsistency.

This paper develops a novel theory of abstraction—what we call collective abstraction. The theory solves a notorious problem for noneliminative structuralism. The noneliminative structuralist holds that in addition to various isomorphic systems there is a pure structure that can be abstracted from each of these systems; but existing accounts of abstraction fail for nonrigid systems like the complex numbers. The problem with the existing accounts is that they attempt to define a unique abstraction operation. The theory of collective abstraction instead (...) simultaneously defines a collection of distinct abstraction operations, each of which maps a system to its corresponding pure structure. The theory is precisely formulated in an essentialist language. This allows us to throw new light on the question to what extent structuralists are committed to symmetric dependence. Finally, we apply the theory of collective abstraction to solve a problem about converse relations. (shrink)

How does vagueness interact with metaphysical modality and with restrictions of it, such as nomological modality? In particular, how do definiteness, necessity (understood as restricted in some way or not), and actuality interact? This paper proposes a model-theoretic framework for investigating the logic and semantics of that interaction. The framework is put forward in an ecumenical spirit: it is intended to be applicable to all theories of vagueness that express vagueness using a definiteness (or: determinacy) operator. We will show how (...) epistemicists, supervaluationists, and theorists of metaphysical vagueness like Barnes and Williams (2010) can interpret the framework.  We will also present a complete axiomatization of the logic we recommend to both epistemicists and local supervaluationists. .

Using only uncontentious principles from the logic of ground I construct an infinitely descending chain of ground without a lower bound. I then compare the construction to the constructions due to Dixon and Rabin and Rabern.

Seemingly natural principles about the logic of ground generate cycles of ground; how can this be if ground is asymmetric? The goal of the theory of decycling is to find systematic and principled ways of getting rid of such cycles of ground. In this paper—drawing on graph-theoretic and topological ideas—I develop a general framework in which various theories of decycling can be compared. This allows us to improve on proposals made earlier by Fine and Litland. However, it turns out (...) that there is no unique method of decycling. An important upshot is that the notion of asymmetric ground may be indeterminate. (shrink)

Jon Erling Litland’s “Meta-Ground” is concerned with the question: If A grounds B, what grounds the fact that A grounds B? His chapter begins by discussing what turns on this question. The chapter then compares the two main existing solutions to the problem of meta-ground. It ends by discussing how the problem of meta-ground is connected to other issues in the theory of ground and what are the main issues for future research.

This article develops the Pure Logic of Iterated Full Ground (PLIFG), a logic of ground that can deal with claims of the form “ϕ grounds that (ψ grounds θ)”—what we call iterated grounding claims. The core idea is that some truths Γ ground a truth ϕ when there is an explanatory argument (of a certain sort) from premisses Γ to conclusion ϕ. By developing a deductive system that distinguishes between explanatory and nonexplanatory arguments we can give introduction rules for operators (...) for factive and nonfactive full ground, as well as for a propositional “identity” connective. Elimination rules are then found by using a proof-theoretic inversion principle. (shrink)

In “Proof-Theoretic Justification of Logic”, building on work by Dummett and Prawitz, I show how to construct use-based meaning-theories for the logical constants. The assertability-conditional meaning-theory takes the meaning of the logical constants to be given by their introduction rules; the consequence-conditional meaning-theory takes the meaning of the logical constants to be given by their elimination rules. I then consider the question: given a set of introduction rules \, what are the strongest elimination rules that are validated by an assertability (...) conditional meaning-theory based on \? I prove that the intuitionistic introduction rules are the strongest rules that are validated by the intuitionistic elimination rules. I then prove that intuitionistic logic is the strongest logic that can be given either an assertability-conditional or consequence-conditional meaning-theory. In “Grounding Grounding” I discuss the notion of grounding. My discussion revolves around the problem of iterated grounding-claims. Suppose that \ grounds \; what grounds that \ grounds that \? I argue that unless we can get a satisfactory answer to this question the notion of grounding will be useless. I discuss and reject some proposed accounts of iterated grounding claims. I then develop a new way of expressing grounding, propose an account of iterated grounding-claims and show how we can develop logics for grounding. In “Is the Vagueness Argument Valid?” I argue that the Vagueness Argument in favor of unrestricted composition isn’t valid. However, if the premisses of the argument are true and the conclusion false, mereological facts fail to supervene on non-mereological facts. I argue that this failure of supervenience is an artifact of the interplay between the necessity and determinacy operators and that it does not mean that mereological facts fail to depend on non-mereological facts. I sketch a deflationary view of ontology to establish this. (shrink)

This book is a creative, original argument about the variety of forms of expression across the history of philosophy.

Søren Kierkegaard: Subjectivity, Irony, and the Crisis of Modernity examines the thought of Søren Kierkegaard, a unique figure, who has inspired, provoked, fascinated, and irritated people ever since he walked the streets of Copenhagen. At the end of his life, Kierkegaard said that the only model he had for his work was the Greek philosopher Socrates. This work takes this statement as its point of departure. Jon Stewart explores what Kierkegaard meant by this and to show how different aspects of (...) his writing and argumentative strategy can be traced back to Socrates. The main focus is The Concept of Irony, which is a key text at the beginning of Kierkegaard's literary career. Although it was an early work, it nevertheless played a determining role in his later development and writings. Indeed, it can be said that it laid the groundwork for much of what would appear in his later famous books such as Either/Or and Fear and Trembling. (shrink)

Dans un monde qui a commencé à prendre feu, la stratégie à adopter se pose à présent comme une question vitale. Il n'y a plus le droit à l'erreur, chaque échec stratégique peut coûter extrêmement cher. En nous rappelant de grandes victoires de l'histoire des luttes non-violentes, mais aussi des campagnes plus récentes comme celles des 'Décrocheurs de portraits' ou des 'grèves scolaires pour le climat,' l'auteur nous invite à cesser d'être spectateur et à devenir acteur de l'histoire. Comment agir (...) face à l'urgence climatique et à l'inaction de nos dirigeants? Avec quelles méthodes? Comment lutter efficacement contre le capitalisme et provoquer des changements culturels de grande ampleur? Comment résister à la répression? La Bataille du siècle--véritable manuel d'action civique et politique--propose des stratégies d'action concrètes pour faire émerger un mouvement citoyen de masse: désobéissance civile, non-violence radicale, convergence des luttes climatiques et sociales, complémentarité des alternatives et des résistances, réconciliation du local et du global... Jon Palais nous appelle à transformer la sidération en espérance, car, il en est convaincu, un autre monde est possible.."--Page 4 of cover. (shrink)

In his Lectures on the Philosophy of Religion, Hegel treats the religions of the world under the rubric "the determinate religion." This is a part of his corpus that has traditionally been neglected since scholars have struggled to understand what philosophical work it is supposed to do. In Hegel's Interpretation of the Religions of the World, Jon Stewart argues that Hegel's rich analyses of Buddhism, Hinduism, Zoroastrianism, Judaism, Egyptian and Greek polytheism, and the Roman religion are not simply irrelevant historical (...) material, as is often thought. Instead, they play a central role in Hegel's argument for what he regards as the truth of Christianity. Hegel believes that the different conceptions of the gods in the world religions are reflections of individual peoples at specific periods in history. These conceptions might at first glance appear random and chaotic, but there is, Hegel claims, a discernible logic in them. Simultaneously, a theory of mythology, history, and philosophical anthropology, Hegel's account of the world religions goes far beyond the field of philosophy of religion. The controversial issues surrounding his treatment of the non-European religions are still very much with us today and make his account of religion an issue of continued topicality in the academic landscape of the twenty-first century.

In recent years interest in the thought of Kierkegaard has grown dramatically, and with it the body of secondary literature has expanded so quickly that it has become impossible for even the most conscientious scholar to keep pace. The problem of the explosion of secondary literature is made more acute by the fact that much of what is written about Kierkegaard appears in languages that most Kierkegaard scholars do not know. Kierkegaard has become a global phenomenon, and new research traditions (...) have emerged in different languages, countries, and regions. The present volume is dedicated to trying to help to resolve these two problems in Kierkegaard studies. Its purpose is, first, to provide book reviews of some of the leading monographic studies in the Kierkegaard secondary literature so as to assist the community of scholars to become familiar with the works that they have not read for themselves. The aim is thus to offer students and scholars of Kierkegaard a comprehensive survey of works that have played a more or less significant role in the research. Second, the present volume also tries to make accessible many works in the Kierkegaard secondary literature that are written in different languages and thus to give a glimpse into various and lesser-known research traditions. The six tomes of the present volume present reviews of works written in Catalan, Chinese, Czech, Danish, Dutch, English, Finnish, French, Galician, German, Greek, Hebrew, Hungarian, Italian, Japanese, Norwegian, Polish, Portuguese, Romanian, Russian, Slovak, Spanish, and Swedish.

In this essay I distinguish categories of animals by their mental capacities. I then discuss whether punishment can be appropriate for animals of each category, and if so what form punishment may appropriately take for animals of each category. The aim is to illuminate each type of punishment through comparison and contrast with the others. This both forestalls the overintellectualization of punishment which arises from viewing humans as the only paradigm case and forestalls the underintellectualization of human punishment which results (...) from making no essential reference, in an account of human punishment, to the human capacity for specifically critical reasoning.

Across the array of topics explored in this comprehensive volume, philosopher and psychoanalyst Jon Mills argues for a fundamental return to the question and meaning of existence. Drawing on the traditions of German Idealism, existentialism, and onto-phenomenology, he offers a rich tapestry of insight and critique into the foundations of psyche, human nature, and society.

In Walter Chatton on Future Contingents, Jon Bornholdt presents the first full-length translation, commentary, and analysis of the various attempts by Chatton (14th century C.E.) to solve the ancient problem of the status and significance of statements about the future. At issue is the danger of so-called logical determinism: if it is true now that a human will perform a given action tomorrow, is that human truly free to perform or refrain from performing that action? Bornholdt shows that Chatton constructed (...) an original (though problematic) formal analysis that enabled him to canvass various approaches to the problem at different stages of his career, at all times showing an unusual sensitivity to the tension between formalist and metaphysical types of solution.

A classicist, philosopher, and poet, Poul Martin Møller was an important figure in the Danish Golden Age. The traumatic event of the death of his wife led him to think more profoundly about the question of the immortality of the soul. In 1837 he published his most important philosophical treatise, "Thoughts on the Possibility of Proofs of Human Immortality," presented here in English for the first time. It was read and commented upon by the leading figures of the Golden Age, (...) such as Søren Kierkegaard. It proved to be the last important work that Møller wrote before his death in March of 1838 at the age of 43. (shrink)

Cultivating trusting psychotherapy bonds is complex, challenging, and a critically important topic. In Trusting in Psychotherapy, the author posits that trusting cannot be understood apart from trustworthiness and that therapists should give equal attention to the task of becoming trustworthy to their patients. Blending developmental science and ethical thought, the author elucidates such topics as what it means to trust in the practice of psychotherapy; the many facets of trusting and trustworthiness; attachment relationships; the central role of hope in trust; (...) and the ethical-moral basis of trusting and trustworthiness.

Aesthetic judgements formed on the basis of testimony are commonly held to be defective, illegitimate, or otherwise problematic. This first book-length treatment of the debate surrounding aesthetic testimony argues for the surprising conclusion that this widespread view is mistaken. Aesthetic testimony is in no way inferior as a source of judgement when compared to either first-hand aesthetic judgement, or testimony concerning non-aesthetic matters. Alongside establishing this position (an extreme form of ‘optimism concerning aesthetic testimony’) this work also responds to the (...) most prominent arguments for the opposing view (‘pessimism concerning aesthetic testimony’). Along the way, it also re-examines our understanding of the norms which govern both judgement and assertion in aesthetics. (shrink)

The Danish Golden Age of the first half of the nineteenth century endured in the midst of a number of different kinds of crisis -- political, economic, and cultural. The many changes of the period made it a dynamic time, one in which artists, poets, philosophers, and religious thinkers were constantly reassessing their place in society. This book traces the different aspects of the cultural crisis of the period through a series of case studies of key figures, including Johan Ludvig (...) Heiberg, Hans Lassen Martensen, and Søren Kierkegaard. Far from just a historical analysis, however, the book shows that many of the key questions that Danish society wrestled with during the Golden Age remain strikingly familiar today."--Publisher's website.

With contributions by scholars from different religions and specializations, this volume explores the potential of nondualism as a fundamentally unifying concept. In every case, we find that nondualism is universal in its relevance yet distinctive and original in its contribution.

Language maps signals onto meanings through the use of two distinct types of structure. First, the space of meanings is discretized into categories that are shared by all users of the language. Second, the signals employed by the language are compositional: The meaning of the whole is a function of its parts and the way in which those parts are combined. In three iterated learning experiments using a vast, continuous, open-ended meaning space, we explore the conditions under which both structured (...) categories and structured signals emerge ex nihilo. While previous experiments have been limited to either categorical structure in meanings or compositional structure in signals, these experiments demonstrate that when the meaning space lacks clear preexisting boundaries, more subtle morphological structure that lacks straightforward compositionality—as found in natural languages—may evolve as a solution to joint pressures from learning and communication.

The semeiotic of Charles Sanders Peirce is irreducibly triadic, positing that a sign mediates between the object that determines it and the interpretant that it determines. He eventually holds that each sign has two objects and three interpretants, standardizing quickly on immediate and dynamical for the objects but experimenting with a variety of names for the interpretants. The two most prominent terminologies are immediate/dynamical/final and emotional/energetic/logical, and scholars have long debated how they are related to each other. This paper seeks (...) to shed new light on the matter by reviewing the numerous manuscript drafts where Peirce develops the latter nomenclature while attempting to introduce his pragmatism to a general audience. It then goes on to examine an additional set of interpretants, intentional/effectual/communicational, and shows that the three different trichotomies can be understood as complementary, rather than redundant or conflicting.

Modern philosophy recognizes two major ethical theories: deontology, which encourages adherence to rules and fulfillment of duties or obligations; and consequentialism, which evaluates morally significant actions strictly on the basis of their actual or anticipated outcomes. Both involve the systematic application of universal abstract principles, reflecting the culturally dominant paradigm of technical rationality. Professional societies promulgate codes of ethics with which engineers are expected to comply, while courts and the public generally assign liability to engineers primarily in accordance with the (...) results of their work, whether intended or unintended. A third option, prominent in ancient philosophy, has reemerged recently: virtue ethics, which recognizes that sensitivity to context and practical judgment are indispensable in particular concrete situations, and therefore rightly focuses on the person who acts, rather than the action itself. Beneficial character traits—i.e., virtues—are identified within a specific social practice in light of the internal goods that are unique to it. This paper proposes a comprehensive framework for implementing virtue ethics within engineering. (shrink)
