Physicians have a sacred commitment to dedicate themselves through their art and through science to the improvement of the human condition. They have the solemn responsibility to focus on both the prevention and the cure of disease. The human genome project, a 15-year effort to draw the first detailed map in human DNA, will inevitably lead to the widespread implementation of human-gene therapy for the treatment and prevention of disease. We are on the verge of nothing less than a biomedical (...) revolution, the likes of which have not been encountered before. The human genome project will lead to profound changes in the ability to manipulate genes. It will change the way we are born, how we live, how we die, and how we view ourselves in relation to our destiny. Before us lies a difficult transition. (shrink)

Substantivism is a general philosophical methodology advocating a substantive approach to philosophical theorizing. In this article, I present an overview of this methodology with a special emphasis on the field of truth. I begin with a framework for understanding what is at stake in the substantivist–deflationist debate and describe the substantivist critique of deflationism. I then proceed to discuss contemporary substantivism as a positive methodology, present examples of recent substantivist theories of truth, delineate several principles of philosophical substantivism, and connect (...) it to contemporary thought about the nature and methods of philosophy. Due to limitations of space, I am unable to discuss all the forms contemporary substantivism has taken. But I try to give a clear sense of the central principles, challenges, and promise of this methodology. (shrink)

Two central themes of Douglas Edwards’s The Metaphysics of Truth are anti-deflationism and substantial pluralism. In Part I of this paper I discuss Edwards’s grounds for rejecting deflationism and suggest a few additional grounds. In Part II I discuss Edward's truth-pluralism and respond to his criticism of my correspondence-pluralism. While these pluralisms share significant features, their differences also raise several important questions.

Artificial Intelligence in the form of different machine learning models is applied to Big Data as a way to turn data into valuable knowledge. The rhetoric is that ensuing predictions work well—with a high degree of autonomy and automation. We argue that we need to analyze the process of applying machine learning in depth and highlight at what point human knowledge production takes place in seemingly autonomous work. This article reintroduces classification theory as an important framework for understanding such seemingly (...) invisible knowledge production in the machine learning development and design processes. We suggest a framework for studying such classification closely tied to different steps in the work process and exemplify the framework on two experiments with machine learning applied to Facebook data from one of our labs. By doing so we demonstrate ways in which classification and potential discrimination take place in even seemingly unsupervised and autonomous models. Moving away from concepts of non-supervision and autonomy enable us to understand the underlying classificatory dispositifs in the work process and that this form of analysis constitutes a first step towards governance of artificial intelligence.

The present crisis of truth, the "post-truth" crisis, puts the philosophy of truth in a new light. It calls for a reexamination of the tasks of the philosophy of truth and sets a new adequacy condition on this philosophy. One of the central roles of the philosophy of truth is to explain the importance of truth for human life and civilization. Among other things, it has to explain what is, or will be, lost in a post-truth era. Clearly, the deflationist (...) answer that the role of truth is to serve as a tool of generalization and oblique endorsement will not do. My account of truth in this paper addresses this task. Truth, I argue, is first and foremost a human value. Its importance to our life/civilization lies, not exclusively, but principally, in the centrality of this value to our humanity. I investigate the ramifications of this answer to the issues discussed in the contemporary philosophy of truth, and I end with a comparison of the substantivist and deflationist approaches to truth in light of this new perspective.

The problem that motivates me arises from a constellation of factors pulling in different, sometimes opposing directions. Simplifying, they are: (1) The complexity of the world; (2) Humans’ ambitious project of theoretical knowledge of the world; (3) The severe limitations of humans’ cognitive capacities; (4) The considerable intricacy of humans’ cognitive capacities . Given these circumstances, the question arises whether a serious notion of truth is applicable to human theories of the world. In particular, I am interested in the questions: (...) (a) Is a substantive standard of truth for human theories of the world possible? (b) What kind of standard would that be? (shrink)

To understand logic is, first and foremost, to understand logical consequence. This Element provides an in-depth, accessible, up-to-date account of and philosophical insight into the semantic, model-theoretic conception of logical consequence, its Tarskian roots, and its ideas, grounding, and challenges. The topics discussed include: the passage from Tarski's definition of truth to his definition of logical consequence, the need for a non-proof-theoretic definition, the idea of a semantic definition, the adequacy conditions of preservation of truth, formality, and necessity, the nature, (...) structure, and totality of models, the logicality problem that threatens the definition of logical consequence, a general solution to the logicality, formality, and necessity problems/challenges, based on the isomorphism-invariance criterion of logicality, philosophical background and justification of the isomorphism-invariance criterion, and major criticisms of the semantic definition and the isomorphism-invariance criterion.

What is death and why does it matter to us? How should the knowledge of our finitude affect the living of our lives and what are the virtues suitable to mortal beings? Does death destroy the meaningfulness of lives, or would lives that never ended be eternally and absurdly tedious? Should we reconcile ourselves to the fact of our forthcoming death, or refuse to "go gently into that good night"? Can death really be an evil if, after death, we no (...) longer exist as subjects of goods or evils? How should we respond to the deaths of others and do we have any duties towards the dead? These, and many other, questions are addressed in Geoffrey Scarre's book, which draws upon a wide variety of philosophical and literary sources to offer an up-to-date and highly readable study of some major ethical and metaphysical riddles concerning death and dying.

This paper is a critical discussion of the recent tendency to moralize various aspects of life that were previously viewed as private and discretionary. The paper takes as its starting point six recently unearthed moral prohibitions, and it examines the prospects for defending each as an extension of some familiar moral requirement. Its conclusion is not only that none of the extended prohibitions are defensible, but also that each impedes morality's function by limiting the ability of those whose lives it (...) governs to pursue their own aims as they see fit.

In the early part of the 20th century the logical positivists launched a powerful attack on traditional philosophy, rejecting the very idea of philosophy as a substantive discipline and replacing it with a practical, conventionalist, meta-theoretical view of philosophy. The positivist critique was based on a series of dichotomies: the analytic vs. the synthetic, the external vs. the internal, the apriori vs. the empirical, the meta-theoretical vs. the object- theoretical, the conventional vs. the factual. Quine's attack on the positivists' dichotomies (...) was, by extension (if not by intention), also an attack on their critique of philosophy. Quine's own theory, however, in time took an extreme naturalistic turn that, if anything, deepened the schism between philosophy and knowledge. -/- In this paper I show that many of Quine's early philosophical ideas - his denial of the analytic-synthetic distinction, his thesis of the interconnectedness of knowledge, his universal revisability thesis, his principle of the inseparability of language and theory, his methodological pragmatism, and his realism - are in fact compatible with a substantive philosophy. Moreover, certain inner tensions in Quine's theory naturally lead to a new model of knowledge in which philosophy plays a substantive role: not as a "first philosophy", or as a "meta-science", or as a "chapter in psychology", but as an independent discipline in its own right, alongside, continuous with, and complementary to, science.

Dissent is a word we come across frequently these days. We read it in the newspapers, use it in discussions with friends and colleagues—perhaps even engage in the activity ourselves. And yet for all of its popularity, few of us, if pressed, would be able to pin down exactly what dissent is. It is this question I wish to explore in this paper. In particular my aim will be to provide a conceptual analysis of the idea of dissent such that (...) we may more cleanly distinguish it from other related forms of disagreement. I use a recent book written on the topic by Ronald Collins and David Skover as an argumentative foil. (shrink)

The paper seeks to answer two new questions about truth and scientific change: What lessons does the phenomenon of scientific change teach us about the nature of truth? What light do recent developments in the theory of truth, incorporating these lessons, throw on problems arising from the prevalence of scientific change, specifically, the problem of pessimistic meta-induction?

Following Henkin's discovery of partially-ordered (branching) quantification (POQ) with standard quantifiers in 1959, philosophers of language have attempted to extend his definition to POQ with generalized quantifiers. In this paper I propose a general definition of POQ with 1-place generalized quantifiers of the simplest kind: namely, predicative, or "cardinality" quantifiers, e.g., "most", "few", "finitely many", "exactly α", where α is any cardinal, etc. The definition is obtained in a series of generalizations, extending the original, Henkin definition first to a general (...) definition of monotone-increasing (M↑) POQ and then to a general definition of generalized POQ, regardless of monotonicity. The extension is based on (i) Barwise's 1979 analysis of the basic case of M↑ POQ and (ii) my 1990 analysis of the basic case of generalized POQ. POQ is a non-compositional Ist-order structure, hence the problem of extending the definition of the basic case to a general definition is not trivial. The paper concludes with a sample of applications to natural and mathematical languages. (shrink)

Just how realistic about human nature and real possibilities must a theory of justice, or a moral theory, more generally, be? Lines have been drawn, with some holding that idealizing away from reality is indispensable and others maintaining that utopian thinking is not just useless but irrelevant. In Utopophobia David Estlund defends the value of utopian theory. At his most modest, Estlund claims that it is a legitimate approach, not ruled out of court by anti-idealists on entirely inadequate grounds—merely “by (...) assumption or definition” as he puts it. Yet he also argues against what we call real world theory, which takes account of human imperfection and feasible options. It invites complacency and undermines aspiration, he argues, and he accepts Rawls’ claim that it will of necessity be unsystematic, thanks to its realism. We accept that the utopian approach is neither useless nor irrelevant. Yet we press hard against the charges against real world theory, maintaining that, properly understood, it invites neither complacency nor aspiration and can perfectly well offer a systematic and principled account of normative concepts, including justice specifically.

Knowledge requires both freedom and friction . Freedom to set up our epistemic goals, choose the subject matter of our investigations, espouse cognitive norms, design research programs, etc., and friction (constraint) coming from two directions: the object or target of our investigation, i.e., the world in a broad sense, and our mind as the sum total of constraints involving the knower. My goal is to investigate the problem of epistemic friction, the relation between epistemic friction and freedom, the viability of (...) foundationalism as a solution to the problem of friction, an alternative solution in the form of a neo-Quinean model, and the possibility of solving the problem of friction as it applies to logic and the philosophy of logic within that model.

The paper compares two theories of the nature of logic: Penelope Maddy's and my own. The two theories share a significant element: they both view logic as grounded not just in the mind (language, concepts, conventions, etc.), but also, and crucially, in the world. But the two theories differ in significant ways as well. Most distinctly, one is an anti-holist, "austere naturalist" theory while the other is a non-naturalist "foundational-holistic" theory. This methodological difference affects their questions, goals, orientations, the scope (...) of their investigations, their logical realism (the way they ground logic in the world), their explanation of the modal force of logic, and their approach to the relation between logic and mathematics. The paper is not polemic. One of its goal is a perspicuous description and analysis of the two theories, explaining their differences as well as commonalities. Another goal is showing that and how (i) a grounding of logic is possible, (ii) logical realism can be arrived at from different perspectives and using different methodologies, and (iii) grounding logic in the world is compatible with a central role for the human mind in logic.

In responding to an essay by Marianne Hirsch and Leo Spitzer about photographs taken in the streets of Chernivitsi in the 1940s, and thus in the midst of the Holocaust, this paper seeks to link their concerns to a broader consideration of photography as a modern phenomenon. In the process, the paper provides a brief history of street photography, a genre virtually ignored in standard histories of the photographic medium. The author suggests that Hirsch and Spitzer’s paper bravely reminds us (...) that our fascination with photographs is based not on truth, but on a combination of desire and faith . Their account of street photography in Czernowitz thereby amounts to an interpretation of photographs as dynamic modes of apprehension rather than as static objects from the past that veridically represent it. It is precisely this aspect of photographs that makes them such unusually complicated, ambiguous, and incongruous historical objects. (shrink)

"The four essays in this volume constitute Derrida's most explicit and sustained reflection on the art work as pictorial artifact, a reflection partly by way of philosophical aesthetics, partly by way of a commentary on art works and art scholarship. The illustrations are excellent, and the translators, who clearly see their work as both a rendering and a transformation, add yet another dimension to this richly layered composition. Indispensable to collections emphasizing art criticism and aesthetics."—Alexander Gelley, _Library Journal_.

This paper explores ethical issues raised by quadratic voting. We compare quadratic voting to majority voting from two ethical perspectives: the perspective of utilitarianism and that of democratic theory. From a utilitarian standpoint, the comparison is ambiguous: if voter preferences are independent of wealth, then quadratic voting out- performs majority voting, but if voter preferences are polarized by wealth, then majority voting may be superior. From the standpoint of democratic theory, we argue that assess- ments in terms of efficiency are (...) too narrow. Voting institutions and political institutions more generally face a legitimacy requirement. We argue that in the presence of inequalities of wealth, any vote buying mechanism, including quadratic voting, will have a difficult time meeting this requirement. (shrink)

Presidential addresses offer an opportunity to reflect on the history of our subject and where the history of science stands in our own day. Such reflections are particularly appropriate with the fiftieth anniversary of the founding of the British Society for the History of Science which is marked in 1997. Some may consider that looking back over our past is either an unacceptable luxury or an occasion for the kind of celebration that can all too easily degenerate into hagiography and (...) an excuse to rake over the past in a thoroughly uncritical manner. This address – and I trust the events of 1997 – will try to avoid such excesses and instead contribute to the historiography of our subject. (shrink)

Derrida's earlier work has a good deal to say about the question of metaphor. Very strikingly in view of Derrida's later thematic interest in the question of animality, metaphor is also presented in a piece on Edmond Jabès as an “animality of the letter,” as “the primary and infinite equivocality of the signifier as Life”. “White Mythology” argues for a certain irreducibility of “metaphor in the text of philosophy”. The trajectory of Derrida's thought here is especially difficult to capture, but (...) seems to be circling around the question of being itself and to involve a crucial detour via Heidegger, and more notably his notion of the als‐Struktur. This point of Derrida's thinking must also be thought beyond the reach of any ontology and of any “thinking of being,” to which the early remarks on metaphor might seem to be leading us, but which the thought of dissemination always resists.

Philosophers are divided on whether the proof- or truth-theoretic approach to logic is more fruitful. The paper demonstrates the considerable explanatory power of a truth-based approach to logic by showing that and how it can provide (i) an explanatory characterization —both semantic and proof-theoretical—of logical inference, (ii) an explanatory criterion for logical constants and operators, (iii) an explanatory account of logic’s role (function) in knowledge, as well as explanations of (iv) the characteristic features of logic —formality, strong modal force, generality, (...) topic neutrality, basicness, and (quasi-)apriority, (v) the veridicality of logic and its applicability to science, (v) the normativity of logic, (vi) error, revision, and expansion in/of logic, and (vii) the relation between logic and mathematics. The high explanatory power of the truth-theoretic approach does not rule out an equal or even higher explanatory power of the proof-theoretic approach. But to the extent that the truth-theoretic approach is shown to be highly explanatory, it sets a standard for other approaches to logic, including the proof-theoretic approach. (shrink)

In a critical scene deeply troubled by questions of justice and responsibility, and beset by political and moral scandals, no issue in recent years has been more urgent or more unsettled than the question of ethics. Geoffrey Galt Harpham, whose previous book, The Ascetic Imperative in Culture and Criticism, was one of the first to announce the critical renewal of ethics, attempts in this new book to explain why ethical questions resist settlement. He urges a new account of ethics (...) not as a stable set of principles, values, or prescriptions, but as a variable factor of "imperativity" immanent in language, analysis, narrative, and creation.

Confronting the Liar Paradox is commonly viewed as a prerequisite for developing a theory of truth. In this paper I turn the tables on this traditional conception of the relation between the two. The theorist of truth need not constrain his search for a “material” theory of truth, i.e., a theory of the philosophical nature of truth, by committing himself to one solution or another to the Liar Paradox. If he focuses on the nature of truth (leaving issues of formal (...) consistency for a later stage), he can arrive at material principles that prevent the Liar Paradox from arising in the first place. I argue for this point both on general methodological grounds and by example. The example is based on a substantivist theory of truth that emphasizes the role of truth in human cognition. The key point is that truth requires a certain complementarity of “immanence” and “transcendence”, and this means that some hierarchical structure is inherent in truth. Approaching the Liar Paradox from this perspective throws new light on its existent solutions: their differences and commonalities, their purported ad-hocness, and the relevance of natural language and bivalence to truth and the Liar.

Kant is known for having said relatively little about truth in Critique of Pure Reason. Nevertheless, there are important lessons to be learned from this work about truth, lessons that apply to the contemporary debate on the nature and structure of truth and its theory. In this paper I suggest two such lessons. The first lesson concerns the structure of a substantive theory of truth as contrasted with a deflationist theory; the second concerns the structure of a correspondence theory of (...) truth. The first lesson warns us against conceiving of a substantive theory of truth in a way that led Kant to conclude that such a theory is unviable. In so doing it indirectly suggests what a viable substantive theory of truth would be like. The second lesson teaches us that a correspondence theory of truth need not be as naive and overly simplistic as it is usually thought to be, but can, and should be, far more complex. This lesson is based on a correspondence theory of truth incipient in the Critique, one whose structure reflects the complexity of the relation between mind and world in Kant’s theory. (shrink)

Considerable evidence has demonstrated that people are not only sensitive to the information contained in concrete imagistic gesture, but furthermore, that they combine this gestural information with the accompanying speech in order to understand the full semantic meaning that a speaker conveys in a message. There is, however, very little experimental evidence concerning how people deal with more abstract metaphoric gestures and whether they extract meaning from these gestures and combine this with the information in the accompanying speech. The two (...) studies reported here investigated this issue by comparing and contrasting the effects of metaphoric gesture-speech matches and mismatches on both semantic communication and social judgment. The studies found that individuals do combine the information contained in metaphoric gestures with that contained in speech and that the meaning of the utterance is demonstrably affected by the presence of a gesture-speech mismatch. The second study found that in messages in which there are gesture-speech mismatches, participants seemed to like the speaker less and were less likely to believe what they said. The implications of these studies for a range of domains, including advertising and politics, are discussed. (shrink)

In this paper I investigate Putnam’s model-theoretic argument from a transcendent standpoint, in spite of Putnam’s well-known objections to such a standpoint. This transcendence, however, requires ascent to something more like a Tarskian meta-level than what Putnam regards as a “God’s eye view”. Still, it is methodologically quite powerful, leading to a significant increase in our investigative tools. The result is a shift from Putnam’s skeptical conclusion to a new understanding of realism, truth, correspondence, knowledge, and theories, or certain aspects (...) thereof, based on, among other things, a better understanding of what models are designed (and not designed) to do.

The viability of metaphysics as a field of knowledge has been challenged time and again. But in spite of the continuing tendency to dismiss metaphysics, there has been considerable progress in this field in the 20th- and 21st- centuries. One of the newest − though, in a sense, also oldest − frontiers of metaphysics is the grounding project. In this paper I raise a methodological challenge to the new grounding project and propose a constructive solution. Both the challenge and its (...) solution apply to metaphysics in general, but grounding theory puts the challenge in an especially sharp focus. The solution consists of a new methodology, holistic grounding or holistic metaphysics. This methodology is modeled after a recent epistemic methodology, foundational holism, that enables us to pursue the foundational project of epistemology without being hampered by the problems associated with foundationalism.

In this paper I discuss Mark Steiner’s view of the contribution of mathematics to physics and take up some of the questions it raises. In particular, I take up the question of discovery and explore two aspects of this question – a metaphysical aspect and a related epistemic aspect. The metaphysical aspect concerns the formal structure of the physical world. Does the physical world have mathematical or formal features or constituents, and what is the nature of these constituents? The related (...) epistemic question concerns humans’ cognitive ability to reach the formal structure of the physical world. Among other things, I explore the interaction of mathematical and non-mathematical cognition in physical discovery. (shrink)
