Proposals to make us smarter than the greatest geniuses or to add thousands of years to our life spans seem fit only for the spam folder or trash can. And yet this is what contemporary advocates of radical enhancement offer in all seriousness. They present a variety of technologies and therapies that will expand our capacities far beyond what is currently possible for human beings. In _Humanity's End,_ Nicholas Agar argues against radical enhancement, describing its destructive consequences. Agar examines (...) the proposals of four prominent radical enhancers: Ray Kurzweil, who argues that technology will enable our escape from human biology; Aubrey de Grey, who calls for anti-aging therapies that will achieve "longevity escape velocity"; Nick Bostrom, who defends the morality and rationality of enhancement; and James Hughes, who envisions a harmonious democracy of the enhanced and the unenhanced. Agar argues that the outcomes of radical enhancement could be darker than the rosy futures described by these thinkers. The most dramatic means of enhancing our cognitive powers could in fact kill us; the radical extension of our life span could eliminate experiences of great value from our lives; and a situation in which some humans are radically enhanced and others are not could lead to tyranny of posthumans over humans.

In the first in-depth philosophical study of the subject, Nicholas Gier examines the published and unpublished writings of Ludwig Wittgenstein, to show the striking parallels between Wittgenstein and phenomenology. Between 1929 and 1933, the philosopher proposed programs that bore a detailed resemblance to dominant themes in the phenomenology of Husserl and some “life-world” phenomenologists. This sound, thoroughly readable study examines how and why he eventually moved away from it. Gier demonstrates, however, that Wittgenstein’s phenomenology continues as his “grammar” of (...) the post-1933 works, which continue to present instructive parallels with Heidegger and Merleau-Ponty.

This volume is about abstract objects and the ways we refer to them in natural language. Asher develops a semantical and metaphysical analysis of these entities in two stages. The first reflects the rich ontology of abstract objects necessitated by the forms of language in which we think and speak. A second level of analysis maps the ontology of natural language metaphysics onto a sparser domain--a more systematic realm of abstract objects that are fully analyzed. This second level reflects the (...) commitments of real metaphysics. The models for these commitments assign truth conditions to natural language discourse.

This book is a general introduction to the philosophy of John Locke, one of the most influential thinkers in modern times. Nicholas Jolley aims to show the fundamental unity of Locke's thought in his masterpiece, the Essay Concerning Human Understanding. In this work Locke advances a coherent theory of knowledge; as against Descartes he argues that knowledge is possible to the extent that it concerns essences which are constructions of the human mind.

Are bacteriophage T4 and the long-nosed elephant fish valuable in their own right? Nicholas Agar defends an affirmative answer to this question by arguing that anything living is intrinsically valuable. This claim challenges received ethical wisdom according to which only human beings are valuable in themselves. The resulting biocentric or life-centered morality forms the platform for an ethic of the environment. -/- Agar builds a bridge between the biological sciences and what he calls "folk" morality to arrive at a (...) workable environmental ethic and a new spectrum--a new hierarchy--of living organisms. The book overturns common-sense moral belief as well as centuries of philosophical speculation on the exclusive moral significance of humans. Spanning several fields, including philosophy of psychology, philosophy of science, and other areas of contemporary analytic philosophy, Agar analyzes and speaks to a wide array of historic and contemporary views, from Aristotle and Kant, to E. O. Wilson, Holmes Rolston II, and Baird Callicot. The result is a challenge to prevailing definitions of value and a call for a scientifically-informed appreciation of nature. (shrink)

The rapid developments in technologies -- especially computing and the advent of many 'smart' devices, as well as rapid and perpetual communication via the Internet -- has led to a frequently voiced view which Nicholas Agar describes as 'radical optimism'. Radical optimists claim that accelerating technical progress will soon end poverty, disease, and ignorance, and improve our happiness and well-being. Agar disputes the claim that technological progress will automatically produce great improvements in subjective well-being. He argues that radical optimism (...) 'assigns to technological progress an undeserved pre-eminence among all the goals pursued by our civilization'. Instead, Agar uses the most recent psychological studies about human perceptions of well-being to create a realistic model of the impact technology will have. Although he accepts that technological advance does produce benefits, he insists that these are significantly less than those proposed by the radical optimists, and aspects of such progress can also pose a threat to values such as social justice and our relationship with nature, while problems such as poverty cannot be understood in technological terms. He concludes by arguing that a more realistic assessment of the benefits that technological advance can bring will allow us to better manage its risks in future. (shrink)

The experience of having to suffer debilitating pain is far too common in the United States, and many patients continue to be inadequately treated by their doctors. Although many physicians freely admit that their pain management practices may have been somewhat lacking, many more express concern that the prescribing of heightened levels of opioid analgesics may result in closer regulatory scrutiny, criminal investigation, or even criminal prosecution.Although several researchers have examined the regulatory environment and the threat of sanction or harm (...) it poses to physicians and patients, few have examined the likelihood of investigation or prosecution stemming from the aggressive use of opioids in physician-directed pain management. Accordingly, in an effort to assess whether the fear of prosecution is realistic and, if so, what factors contribute to its likelihood, we surveyed chief prosecutors in four states about their knowledge, opinions, and attitudes concerning opioids and the prosecution of physicians stemming from the treatment of patients who were either terminally ill or suffering from chronic noncancer pain.

I hope I have convinced the reader that DR theory offers at least some exciting potential when applied to the semantics of belief reports. It differs considerably from other approaches, and it makes intuitively acceptable predictions that other theories do not. The theory also provides a novel approach to the semantics of other propsitional attitude reports. Further, DR theory enables one to approach the topic of anaphora within belief and other propositional attitude contexts in a novel way, thus combining the (...) semantics developed here with one of the theory's original motivations (Kamp, 1981a). However, these are unfortunately topics that I must reserve for another time. (shrink)

Gottfried Wilhelm Leibniz was hailed by Bertrand Russell as 'one of the supreme intellects of all time'. A towering figure in seventeenth-century philosophy, his complex thought has been championed and satirized in equal measure, most famously in Voltaire's _Candide_. In this outstanding introduction to his philosophy, Nicholas Jolley introduces and assesses the whole of Leibniz's philosophy. Beginning with an introduction to Leibniz's life and work, he carefully introduces the core elements of Leibniz's metaphysics: his theories of substance, identity and (...) individuation; monads and space and time; and his important debate over the nature of space and time with Newton's champion, Samuel Clarke. He then introduces Leibniz's theories of mind, knowledge, and innate ideas, showing how Leibniz anticipated the distinction between conscious and unconscious states, before examining his theory of free will and the problem of evil. An important feature of the book is its introduction to Leibniz's moral and political philosophy, an overlooked aspect of his work. The final chapter assesses legacy and the impact of his philosophy on philosophy as a whole, particularly on the work of Immanuel Kant. Throughout, Nicholas Jolley places Leibniz in relation to some of the other great philosophers, such as Descartes, Spinoza and Locke, and discusses Leibniz's key works, such as the _Monadology_ and _Discourse on Metaphysics_.

In this paper, we address several puzzles concerning speech acts, particularly indirect speech acts. We show how a formal semantictheory of discourse interpretation can be used to define speech acts and to avoid murky issues concerning the metaphysics of action. We provide a formally precise definition of indirect speech acts, including the subclass of so-called conventionalized indirect speech acts. This analysis draws heavily on parallels between phenomena at the speech act level and the lexical level. First, we argue that, just (...) as co-predication shows that some words can behave linguistically as if they're `simultaneously' of incompatible semantic types, certain speech acts behave this way too. Secondly, as Horn and Bayer (1984) and others have suggested, both the lexicon and speech acts are subject to a principle of blocking or "preemption by synonymy": Conventionalized indirect speech acts can block their `paraphrases' from being interpreted as indirect speech acts, even if this interpretation is calculable from Gricean-style principles. We provide a formal model of this blocking, and compare it with existing accounts of lexical blocking. (shrink)

Elselijn Kingma argues that Christopher Boorse’s biostatistical theory (the BST) does not show how the reference classes it uses are objective and naturalistic. Recently, philosophers of medicine have attempted to rebut Kingma’s concerns. I argue that these rebuttals are theoretically unconvincing, and that there are clear examples of physicians adjusting their reference classes according to their prior knowledge of health and disease. I focus on the use of age-adjusted reference classes to diagnose low bone mineral density in children. In addition (...) to using the BST’s age, sex, and species, physicians also choose to use other factors to define reference classes, such as pubertal status, bone age, body size, and muscle mass. I show that physicians calibrate the reference classes they use according to their prior knowledge of health and disease. Reference classes are also chosen for pragmatic reasons, such as to predict fragility fractures. (shrink)

Socrates' attitude towards falsehood is quite puzzling in the Republic. Although Socrates is clearly committed to truth, at several points he discusses the benefits of falsehood. This occurs most notably in Book 3 with the "noble lie" (414d-415c) and most disturbingly in Book 5 with the "rigged sexual lottery" (459d-460c). This raises the question: What kinds of falsehoods does Socrates think are beneficial, and what kinds of falsehoods does he think are harmful? And more broadly: What can this tell us (...) about the relationship between ethics and epistemology? The key to answering these questions lies in an obscure and paradoxical passage in Book II; at 382a-d Socrates distinguishes between "true falsehoods" and "impure lies." True falsehoods are always bad, but impure lies are sometimes beneficial. Despite Socrates' insistence that he is not saying anything deep, his distinction is far from straightforward. Nevertheless, in order to determine why some falsehoods are beneficial and why some are always harmful, we must understand what exactly true falsehoods are and how they differ from impure lies. In this paper, I argue that true falsehoods are a restricted class of false beliefs about ethics; they are false beliefs about how one should live and what one should pursue. I refer to these beliefs as "normative commitments." False normative commitments are always pernicious because they create and sustain psychological disharmony. Unlike true falsehoods, impure lies can be about anything. Nevertheless, they are only beneficial when they help produce and sustain true normative commitments. I argue that the upshot of this is that practical concerns have a kind of primacy over theoretical concerns. (shrink)

Supervaluational accounts of vagueness have come under assault from Timothy Williamson for failing to provide either a sufficiently classical logic or a disquotational notion of truth, and from Crispin Wright and others for incorporating a notion of higher-order vagueness, via the determinacy operator, which leads to contradiction when combined with intuitively appealing ‘gap principles’. We argue that these criticisms of supervaluation theory depend on giving supertruth an unnecessarily central role in that theory as the sole notion of truth, rather than (...) as one mode of truth. Allowing for the co-existence of supertruth and local truth, we define a notion of local entailment in supervaluation theory, and show that the resulting logic is fully classical and allows for the truth of the gap principles. Finally, we argue that both supertruth and local truth are disquotational, when disquotational principles are properly understood. (shrink)

Attempting to compare scientific theories requires a philosophical model of meaning. Yet different scientific theories have at times—particularly in early chemistry—pre-supposed disparate theories of meaning. When two theories of meaning are incommensurable, we must say that the scientific theories that rely upon them are meta-incommensurable. Meta- incommensurability is a more profound sceptical threat to science since, unlike first-order incommensurability, it implies complete incomparability.

In this paper we explore how compositional semantics, discourse structure, and the cognitive states of participants all contribute to pragmatic constraints on answers to questions in dialogue. We synthesise formal semantic theories on questions and answers with techniques for discourse interpretation familiar from computational linguistics, and show how this provides richer constraints on responses in dialogue than either component can achieve alone.

The most constructive response to the crisis in moral theory has been the revival of virtue ethics, which has the advantages of being personal, contextual, and, as will be argued, normative as well. It is also proposed that the best way to refound virtue ethics is to return to the Greek concept of technē tou biou, literally "craft of life." The ancients did not distinguish between craft and fine art, and the meaning of technē, even in its Latin form, ars, (...) still retains the meaning of skillful crafting and discipline. In Greco-Roman culture, techniques were very specific, covering dietetics, economics, and erotics. In ancient China, moral cultivation was intimately connected to the arts, from archery to poetry, music, and dance, such that virtually every activity would have both moral and aesthetic meaning. Using R. D. Collingwood's distinction between craft and fine art, it is proposed that the latter, particularly the performing arts of music and dance, can serve as a model for virtue ethics in our times.

In this paper, we offer a novel analysis of bridging, paying particular attention to definite descriptions. We argue that extant theories don't do justice to the way different knowledge resources interact. In line with Hobbs (1979), we claim that the rhetorical connections between the propositions introduced in the text play an important part. But our work is distinct from his in that we model how this source of information interacts with compositional and lexical semantics. We formalize bridging in a framework (...) known as SDRT (Asher 1993). We demonstrate that this provides a richer, more accurate interpretation of definite descriptions than has been offered so far.

Free choice permission, a crucial test case concerning the semantics/ pragmatics boundary, usually receives a pragmatic treatment. But its pragmatic features follow from its semantics. We observe that free choice inferences are defeasible, and defend a semantics of free choice permission as strong permission expressed in terms of a modal conditional in a nonmonotonic logic.

This paper presents a nonmonotonic deontic logic based on commonsense entailment. It establishes criteria a successful account of obligation should satisfy, and develops a theory that satisfies them. The theory includes two conditional notions of prima facie obligation. One is constitutive; the other is epistemic, and follows nonmonotonically from the constitutive notion. The paper defines unconditional notions of prima facie obligation in terms of the conditional notions.

This paper examines Plato’s conception of shame and the role intoxication plays in cultivating it in the Laws. Ultimately, this paper argues that there are two accounts of shame in the Laws. There is a public sense of shame that is more closely tied to the rational faculties and a private sense of shame that is more closely tied to the non-rational faculties. Understanding this division between public and private shame not only informs our understanding of Plato’s moral psychology, but (...) his political and ethical theory as well. (shrink)

The measurement of diagnostic accuracy is an important aspect of the evaluation of diagnostic tests. Sometimes, medical researchers try to discover the set of observations that are most accurate of all by directly inspecting diseased and not-diseased patients. This method is perhaps intuitively appealing, as it seems a straightforward empirical way of discovering how to identify diseased patients, which amounts to trying to correlate the results of diagnostic tests with disease status. I present three examples of researchers who try to (...) produce definitive diagnostic criteria by directly inspecting diseased and not diseased patients. Despite this method’s intuitive appeal, I will argue that it is impossible to carry out. Before researchers can inspect these patients to discover definitive diagnostic criteria, they must be able to distinguish diseased and not-diseased patients; and they do not know how to do this, because this is what they are trying to discover. I suspect the intuitive appeal of directly inspecting patients makes this difficult to appreciate. To counter this difficulty, I present this problem as a manifestation of ‘Meno’s paradox’, which was described in classical antiquity, and of ‘the problem of nomic measurement’, described more recently. Considering these philosophical problems may help researchers address the methodological issues they face when evaluating diagnostic tests. (shrink)

Plato’s attitude towards drunkenness (μέθη) is surprisingly positive in the Laws, especially as compared to his negative treatment of intoxication in the Republic. In the Republic, Plato maintains that intoxication causes cowardice and intemperance (3.398e-399e, 3.403e, and 9.571c-573b), while in the Laws, Plato holds that it can produce courage and temperance (1.635b, 1.645d-650a, and 2.665c-672d). This raises the question: Did Plato change his mind, and if he did, why? Ultimately, this paper answers affirmatively and argues that this marks a substantive (...) shift in Plato’s attitude towards anti-rational desires. More precisely, this paper argues that in the Republic, Plato holds that anti-rational desires are always detrimental to health and virtue, while in the Laws, Plato maintains that anti-rational desires can be instrumental to health and virtue.

When two people engage in a conversation, knowingly or unknowingly, they are playing a game. Players of such games have diverse objectives, or winning conditions: an applicant trying to convince her potential employer of her eligibility over that of a competitor, a prosecutor trying to convict a defendant, a politician trying to convince an electorate in a political debate, and so on. We argue that infinitary games offer a natural model for many structural characteristics of such conversations. We call such (...) games message exchange games, and we compare them to existing game theoretic frameworks used in linguistics—for example, signaling games—and show that message exchange games are needed to handle non-cooperative conversation. In this paper, we concentrate on conversational games where players’ interests are opposed. We provide a taxonomy of conversations based on their winning conditions, and we investigate some essential features of winning conditions like consistency and what we call rhetorical cooperativity. We show that these features make our games decomposition sensitive, a property we define formally in the paper. We show that this property has far-reaching implications for the existence of winning strategies and their complexity. There is a class of winning conditions for which message exchange games are equivalent to Banach- Mazur games, which have been extensively studied and enjoy nice topological results. But decomposition sensitive goals are much more the norm and much more interesting linguistically and philosophically. (shrink)

A comparative philosophical consideration of the extremes of humanism, or "Titanism," this book critiques trends in Eastern and Western philosophy and examines solutions to them.

In this essay Nicholas C. Burbules reviews his experiences and the lessons he learned as editor of Educational Theory for more than twenty years, and he explores some of the normative choices that are inevitably made by any editor in carrying out his or her role. Burbules examines the relationship of a journal to its intellectual field; the review process; communications and interactions with authors; the process of editing and revising manuscripts; questions of representativeness in a theoretically pluralistic field; (...) the business of journal publishing; and the dilemmas that confront an editor in terms of his or her own position and identity within a field. In all of these reflections, he examines the ethical and political background of the choices made, and how these in turn reveal deeper assumptions about the nature and purpose of academic publishing. The result is to “lift up the curtain” and reveal how one philosophically reflective and self-questioning editor handled his responsibilities. (shrink)

This seminal paper, which marks a turning point of the chemical revolution, is presented for the first time in a complete English translation. In this first half Lavoisier undermines phlogiston chemistry by arguing that his French contemporaries had replaced Stahl’s original theory with radically different systems that conceptualised the phlogiston principle in completely incompatible ways. He refutes their claims by showing that these later models were riddled with inconsistencies as to phlogiston’s weight, its ability to penetrate glass and its role (...) as a source of colour and odour in chemical compounds.

In both the Laches (191d-e) and the Laws (1.633c-d, 1.634a-b, and 1. 635d), Plato has his protagonist defend the claim that courage (andreia) is not simply a matter of resisting pain and fear but about overcoming pleasure and desire as well. In this paper, I argue that Plato took the expansive view of courage seriously and that there are several reasons why we should too.

Plato’s Pragmatism offers the first comprehensive defense of a pragmatist reading of Plato. According to Plato, the ultimate rational goal is not to accumulate knowledge and avoid falsehood but rather to live an excellent human life. The book contends that a pragmatic outlook is present throughout the Platonic corpus. The authors argue that the successful pursuit of a good life requires cultivating certain ethical commitments, and that maintaining these commitments often requires violating epistemic norms. In the course of defending the (...) pragmatist interpretation, the authors present a forceful Platonic argument for the conclusion that the value of truth has its limits, and that what matters most are one’s ethical commitments and the courage to live up to them. Their interpretation has far-reaching consequences in that it reshapes how we understand the relationship between Plato’s ethics and epistemology. Plato’s Pragmatism will appeal to scholars and advanced students of Plato and ancient philosophy. It will also be of interest to those working on current controversies in ethics and epistemology.
