There is considerable likelihood that Gottlob Frege began writing his Foundations of Arithmetic with the expectation that he could introduce his numbers, not with sets, but through some algebraic techniques borrowed from earlier writers of the Gottingen school. These rewriting techniques, had they worked, would have required strong philosophical justification provided by Frege's celebrated "context principle," which otherwise serves little evident purpose in the published Foundations.

Stereological techniques allow biologists to create quantitative, three-dimensional descriptions of biological structures from two- dimensional images of tissue viewed under the microscope. For example, they can accurately estimate the size of a particular organelle, the total length of a mass of capillaries, or the number of neurons or synapses in a particular region of the brain. This book provides a practical guide to designing and critically evaluating stereological studies of the nervous system and other tissues. It explains the basic (...) concepts behind design-based stereology and how to get started. Also included are detailed descriptions of how to prepare tissue appropriately, perform pilot studies and decide on the appropriate sampling strategy, and account for phenomena such as tissue shrinkage. Numerous examples of applications of stereological methods that are applicable to studies of the central system and a wide variety of other tissues are explained. The book is therefore essential reading for neurobiologists and cell biologists interested in generating accurate representations of cell and tissue architecture. (shrink)

Particularists in ethics emphasize that the normative is holistic, and invite us to infer with them that it therefore defies generalization. This has been supposed to present an obstacle to traditional moral theorizing, to have striking implications for moral epistemology and moral deliberation, and to rule out reductive theories of the normative, making it a bold and important thesis across the areas of normative theory, moral epistemology, moral psychology, and normative metaphysics. Though particularists emphasize the importance of the holism of (...) the normative, however, it is not something that they have been able to explain. In this paper I’ll show how to use a small number of simple and, I’ll argue, independently compelling assumptions in order to both predict and explain the holistic features of the normative with respect to the non-normative. The basic idea of the paper is simple. It is that normative claims are holistic because they are general, rather than because they defy generalization. (shrink)

The paper rehearses arguments for and against the prediction of massive technological unemployment. The main argument in favor is that robots are entering a large number of industries; making more expensive human labor redundant. The main argument against the prediction is that for two hundred years we have seen a massive increase in productivity with no long term structural unemployment caused by automation. The paper attempts to move past this argumentative impasse by asking what humans contribute to the supply (...) side of the economy. Historically; humans have contributed muscle and brains to production but we are now being outcompeted by machinery; in both areas; in many jobs. It is argued that this supports the conjecture that massive unemployment is a likely result. It is also argued that a basic income guarantee is a minimal remedial measure to mitigate the worst effects of technological unemployment. (shrink)

Doxastic voluntarism is the thesis that our beliefs are subject to voluntary control. While there’s some controversy as to what “voluntary control” amounts to (see 1.2), it’s often understood as direct control: the ability to bring about a state of affairs “just like that,” without having to do anything else. Most of us have direct control over, for instance, bringing to mind an image of a pine tree. Can one, in like fashion, voluntarily bring it about that one believes a (...) specific proposition? Doxastic voluntarists hold that, at least in some circumstances—such as when the evidence is ambiguous—we can. Doxastic involuntarists, in contrast, maintain that we cannot. Some involuntarists hold that the concept of belief itself precludes the possibility of believing voluntarily. Others hold that the impossibility of voluntary belief is a contingent psychological fact. Historically, the issue of doxastic voluntarism has been connected to how many think about religious commitment: a prominent view of faith is that it is a voluntary decision to believe. Furthermore, the issue of voluntarism has also been viewed as having bearing on fundamental questions in epistemology. For example, are epistemic norms duties to believe in certain ways? Are there practical or moral reasons to believe? If the answer to either question is “yes,” it seems some measure of voluntary doxastic control is required. -/- In section 1, we expand on the definition of doxastic voluntarism, and survey various kinds of control (e.g. direct, indirect, long-range) and the doxastic attitudes we might control (e.g. outright belief, withholding, credences). In section 2, we discuss a number of historical views on doxastic voluntarism. In section 3, we survey motivations for rejecting doxastic voluntarism. There are two general strategies: arguments that appeal to psychological considerations, and conceptual arguments regarding the nature of belief. In section 4, we survey five approaches to defending voluntarism: those that appeal to epistemic permissivism, doxastic compatibilism, skepticism, one-off considerations, and non-standard views of belief. In section 5, we cover empirical work on doxastic voluntarism. The last two sections discuss two implications of voluntarism. In section 6, we discuss voluntarism’s implications for the ethics of belief, and in section 7, we discuss issues at the intersection of voluntarism and religious faith. (shrink)

Mark Jago presents an original philosophical account of meaningful thought: in particular, how it is meaningful to think about things that are impossible. We think about impossible things all the time. We can think about alchemists trying to turn base metal to gold, and about unfortunate mathematicians trying to square the circle. We may ponder whether God exists; and philosophers frequently debate whether properties, numbers, sets, moral and aesthetic qualities, and qualia exist. In many philosophical or mathematical debates, when one (...) side of the argument gets things wrong, it necessarily gets them wrong. As we consider both sides of one of these philosophical arguments, we will at some point think about something that’s impossible. Yet most philosophical accounts of meaning and content hold that we can’t meaningfully think or reason about the impossible. -/- In The Impossible, Jago argues that we often gain new information, new beliefs, and, sometimes, fresh knowledge through logic, mathematics, and philosophy. That is why logic, mathematics, and philosophy are useful. We therefore require accounts of knowledge and belief, of information and content, and of meaning which allow space for the impossible. Jago’s aim in this book is to provide such accounts. He gives a detailed analysis of the concept of hyperintensionality, whereby logically equivalent contents may be distinct, and develops a theory in terms of possible and impossible worlds. Along the way, he provides a theory of what those worlds are and how they feature in our analysis of normative epistemic concepts: knowledge, belief, information, and content. (shrink)

This introduction to the philosophy of mathematics focuses on contemporary debates in an important and central area of philosophy. The reader is taken on a fascinating and entertaining journey through some intriguing mathematical and philosophical territory, including such topics as the realism/anti-realism debate in mathematics, mathematical explanation, the limits of mathematics, the significance of mathematical notation, inconsistent mathematics and the applications of mathematics. Each chapter has a number of discussion questions and recommended further reading from both the contemporary literature (...) and older sources. Very little mathematical background is assumed and all of the mathematics encountered is clearly introduced and explained using a wide variety of examples. The book is suitable for an undergraduate course in philosophy of mathematics and, more widely, for anyone interested in philosophy and mathematics. (shrink)

In his contribution, Mark Alfano lays out a new (to virtue theory) naturalistic way of determining what the virtues are, what it would take for them to be realized, and what it would take for them to be at least possible. This method is derived in large part from David Lewis’s development of Frank Ramsey’s method of implicit definition. The basic idea is to define a set of terms not individually but in tandem. This is accomplished by assembling all and (...) only the common sense platitudes that involve them (e.g., typically, people want to be virtuous), conjoining those platitudes, and replacing the terms in question by existentially quantified variables. If the resulting sentence is satisfied, then whatever satisfies are the virtues. If it isn’t satisfied, there are a couple of options. First, one could just admit defeat by saying that people can’t be virtuous. More plausibly, one could weaken the conjunction by dropping a small number of the platitudes from it (and potentially adding some others). Alfano suggests that the most attractive way to do this is by dropping the platitudes that deal with cross-situational consistency and replacing them with platitudes that involve social construction: basically, people are virtuous (when they are) at least in part because other people signal their expectations of virtuous conduct, which induces virtuous conduct, which in turn induces further signals of expected virtuous conduct, and so on.

After 1989, capitalism has successfully presented itself as the only realistic political-economic system - a situation that the bank crisis of 2008, far from ending, actually compounded. The book analyses the development and principal features of this capitalist realism as a lived ideological framework. Using examples from politics, films, fiction, work and education, it argues that capitalist realism colours all areas of contemporary experience. But it will also show that, because of a number of inconsistencies and glitches internal to (...) the capitalist reality program capitalism in fact is anything but realistic. (shrink)

Experimental moral philosophy began to emerge as a methodology inthe last decade of the twentieth century, a branch of the largerexperimental philosophy approach. From the beginning,it has been embroiled in controversy on a number of fronts. Somedoubt that it is philosophy at all. Others acknowledge that it isphilosophy but think that it has produced modest results at best andconfusion at worst. Still others think it represents an important advance., Before the research program can be evaluated, we should have someconception (...) of its scope. But controversy surrounds questionsabout its boundaries as well. Uncontroversially, the distinctionbetween experimental and non-experimental philosophy is not identicalto the distinction between a posteriori and a prioriphilosophy.

We defend the reliability of Hurlburt's Descriptive Experi-ence Sampling method against some of Schwitzgebel's attacks. But we agree with Schwitzgebel that the method could be used much more widely than it has been, helping to answer questions about the nature and structure of consciousness in addition to cataloguing the latter's contents. We sketch a number of potential lines of further enquiry.

Mathematical fictionalism (or as I'll call it, fictionalism) is best thought of as a reaction to mathematical platonism. Platonism is the view that (a) there exist abstract mathematical objects (i.e., nonspatiotemporal mathematical objects), and (b) our mathematical sentences and theories provide true descriptions of such objects. So, for instance, on the platonist view, the sentence ‘3 is prime’ provides a straightforward description of a certain object—namely, the number 3—in much the same way that the sentence ‘Mars is red’ provides (...) a description of Mars. But whereas Mars is a physical object, the number 3 is (according to platonism) an abstract object. And abstract objects, platonists tell us, are wholly nonphysical, nonmental, nonspatial, nontemporal, and noncausal. Thus, on this view, the number 3 exists independently of us and our thinking, but it does not exist in space or time, it is not a physical or mental object, and it does not enter into causal relations with other objects. This view has been endorsed by Plato, Frege (1884, 1893-1903, 1919), Gödel (1964), and in some of their writings, Russell (1912) and Quine (1948, 1951), not to mention numerous more recent philosophers of mathematics, e.g., Putnam (1971), Parsons (1971), Steiner (1975), Resnik (1997), Shapiro (1997), Hale (1987), Wright (1983), Katz (1998), Zalta (1988), and Colyvan (2001).

Abstract: Recently, the experimental philosopher Joshua Knobe has shown that the folk are more inclined to describe side effects as intentional actions when they bring about bad results. Edouard Machery has offered an intriguing new explanation of Knobe's work—the 'trade-off hypothesis'—which denies that moral considerations explain folk applications of the concept of intentional action. We critique Machery's hypothesis and offer empirical evidence against it. We also evaluate the current state of the debate concerning the concept of intentionality, and argue that, (...) given the number of variables at play, any parsimonious account of the relevant data is implausible.

Measuring gene expression on a global scale has been one of the vexing problems of cell biology. Velculescu et al.(1) recently proposed a system for identifying gene expression levels based on very short sequence tags – about nine base pairs – located at a specific site within a gene transcript. By coupling the strategy to current automated sequencing machines and the large expressed sequence tag databases, it should be possible to follow changes in gene expression for large numbers of genes (...) economically and accurately.

This volume brings together a number of related contributions on the topic of expertise and education. Expertise is a topic that is beginning to receive more attention in the Philosophy of Education and discussions are closely related to the epistemological debate concerning the nature of know-how which has also burgeoned in recent years within ‘mainstream’ epistemology. More specifically, this volume focuses on the relevance of expertise to professional education and practice, with the aim on shedding light on what is (...) involved in professional expertise and the implications of a sound understanding of professional expertise for professional education. Although all contributions have roots in philosophical discussion, there is an element of cross-disciplinarity among them, reflecting the advances that have been made to our understanding of expertise from psychology in particular.

We present statistical analyses of the large‐scale structure of 3 types of semantic networks: word associations, WordNet, and Roget's Thesaurus. We show that they have a small‐world structure, characterized by sparse connectivity, short average path lengths between words, and strong local clustering. In addition, the distributions of the number of connections follow power laws that indicate a scale‐free pattern of connectivity, with most nodes having relatively few connections joined together through a small number of hubs with many connections. (...) These regularities have also been found in certain other complex natural networks, such as the World Wide Web, but they are not consistent with many conventional models of semantic organization, based on inheritance hierarchies, arbitrarily structured networks, or high‐dimensional vector spaces. We propose that these structures reflect the mechanisms by which semantic networks grow. We describe a simple model for semantic growth, in which each new word or concept is connected to an existing network by differentiating the connectivity pattern of an existing node. This model generates appropriate small‐world statistics and power‐law connectivity distributions, and it also suggests one possible mechanistic basis for the effects of learning history variables (age of acquisition, usage frequency) on behavioral performance in semantic processing tasks.

The interactivist model has explored a number of consequences of process metaphysics. These include reversals of some fundamental metaphysical assumptions dominant since the ancient Greeks, and multiple further consequences throughout the metaphysics of the world, minds, and persons. This article surveys some of these consequences, ranging from issues regarding entities and supervenience to the emergence of normative phenomena such as representation, rationality, persons, and ethics.

Philosophy of ecology has been slow to become established as an area of philosophical interest, but it is now receiving considerable attention. This area holds great promise for the advancement of both ecology and the philosophy of science. Insights from the philosophy of science can advance ecology in a number of ways. For example, philosophy can assist with the development of improved models of ecological hypothesis testing and theory choice. Philosophy can also help ecologists understand the role and limitations (...) of mathematical models in ecology. On the other side, philosophy of science will be advanced by having ecological case studies as part of the stock of examples. Ecological case studies can shed light on old philosophical topics as well as raise novel issues for the philosophy of science. For example, understanding theoretical terms such as “biodiversity” is important for scientific reasons, but such terms also carry political importance. Formulating appropriate definitions for such terms is thus not a purely scientific matter, and this may prompt a reevaluation of philosophical accounts of defining theoretical terms. We consider some of the topics currently receiving attention in the philosophy of ecology and other topics in need of attention. Our aim is to prompt further exchange between ecology and philosophy of science and to help set the agenda for future work in the philosophy of ecology. The topics covered include: the role of mathematical models, environmental problem formulation, biodiversity, and environmental ethics. (shrink)

Several researchers have recently argued that p values lose their meaning in exploratory analyses due to an unknown inflation of the alpha level (e.g., Nosek & Lakens, 2014; Wagenmakers, 2016). For this argument to be tenable, the familywise error rate must be defined in relation to the number of hypotheses that are tested in the same study or article. Under this conceptualization, the familywise error rate is usually unknowable in exploratory analyses because it is usually unclear how many hypotheses (...) have been tested on a spontaneous basis and then omitted from the final research report. In the present article, I argue that it is inappropriate to conceptualize the familywise error rate in relation to the number of hypotheses that are tested. Instead, it is more appropriate to conceptualize familywise error in relation to the number of different tests that are conducted on the same null hypothesis in the same study. Under this conceptualization, alpha level adjustments in exploratory analyses are (a) less necessary and (b) objectively verifiable. As a result, p values do not lose their meaning in exploratory analyses. (shrink)

The dominant assumptions -- throughout contemporary philosophy, psychology, cognitive science, and artificial intelligence -- about the ontology underlying intentionality, and its core of representationality, is that of encodings -- some sort of informational or correspondence or covariation relationship between the represented and its representation that constitutes that representational relationship. There are many disagreements concerning details and implementations, and even some suggestions about claimed alternative ontologies, such as connectionism (though none that escape what I argue is the fundamental flaw in these (...) dominant approaches). One assumption that seems to be held by all, however, usually without explication or defense, is that there is _one_ singular underlying ontology to representationality. In this paper, I argue that there are in fact quite a number of ontologies that manifest representationality -- levels of representationality -- and that _none_ of them are the standard "manipulations of encoded symbols" ontology, nor any other variation on the informational approach to representation. Collectively, these multiple representational ontologies constitute a framework for cognition, whether natural or artificial. (shrink)

Contemporary bioethics has been somewhat skewed by its focus on high-tech medicine and the resulting development of ethical frameworks based on an acute-care model of healthcare. Research and scholarship in bioethics have payed only cursory attention to ethical issues related to disability. I argue that bioethics should concern itself with the full range of theoretical and practical issues related to disability. This encounter with the disability community will enrich bioethics and, potentially, society as well. I suggest a number of (...) items that the bioethics agenda should include, such as the development of a casuistry of the right to healthcare and to community integration and an advocacy role in fostering an understanding among the public and policy makers of the need to reform research and treatment related to disability.

Critics of reliability theories of epistemic justificationoften claim that the `generality problem' is an insurmountabledifficulty for such theories. The generality problem is theproblem of specifying the level of generality at which abelief-forming process is to be described for the purposeof assessing its reliability. This problem is not asintractable as it seems. There are illuminating solutionsto analogous problems in the ethics literature. Reliabilistsought to attend to utilitarian approaches to choices betweeninfinite utility streams; they also ought to attend towelfarist approaches to social (...) choice situations that donot demand full aggregation of individual welfares.These analogies suggest that the traditional `single number'approach to reliability is misguided. I argue that a newapproach – the `vector reliability' approach – is preferable.Vector reliability theories associate target beliefs withreliability vectors – that is, structured collections ofreliability numbers – and construct criteria of epistemicjustification that appeal to these vectors. The bulk of thetheoretical labor involved in a reliability account of epistemicjustification is thus transferred from picking a uniquereliability number to constructing a plausible criterionof epistemic justification.

The first part of the essay describes how mathematics, in particular mathematical concepts, are applicable to nature. mathematical constructs have turned out to correspond to physical reality. this correlation between the world and mathematical concepts, it is argued, is a true phenomenon. the second part of this essay argues that the applicability of mathematics to nature is mysterious, in that not only is there no known explanation for the correlation between mathematics and physical reality, but there is a good reason (...) to except no such correlation. it is argued that there is a subjective element in the decision as to what constitutes a mathematical concept. a number of purported solutions to the mystery of the applicability of mathematics to nature are discarded, until we are left with eugene wigner's thesis that we are here confronted with a "miracle that we neither understand nor deserve.".

Owing to a genral dissatisfaction with hedonistic theories of value, a number of recent discussions have sought to identify an agent's selfinterest, individual utility, or personal welfare with what the agent most wants to do, all things considered. Two features of these accounts merit special attention for the argument in this paper. First, on such accounts any desire or aversion which persists in the face of complete information is logically relevant to the determination of an agent's self interest. This (...) includes apparently altruistic desires like a desire for another's happiness as well as more narrow and self-regarding desires like a desire to eat a good meal. Second, when the agent finds himself in a situation where he must choose between incompatible desires, his informed preference determines the act which is most in his self-interest. (shrink)

We all believe an unbounded number of things about the way the world is and about the way the world works. For example, I believe that if I move this book into the other room, it will not change color -- unless there is a paint shower on the way, unless I carry an umbrella through that shower, and so on; I believe that large red trucks at high speeds can hurt me, that trucks with polka dots can hurt (...) me, and so on; that if I move this book, the room will stay in place -- unless there is a pressure switch under the book attached to a bomb, unless the switch communicates to the bomb by radio and there is shielding in the way, and so on; that the moon is not made of green cheese, that the moon is not made of caviar, that the moon is not made of gold, and so on. The problems involved in accounting for such infinite proliferations of beliefs -- and the computations and inferences that take them into account -- are collectively called the Frame Problems, and are considered by some to constitute a major discovery of a new philosophical problem. How could we possibly learn them all? How could the brain possibly hold them all? The problems appear insoluble, impossible. Yet we all learn and hold such unbounded numbers of beliefs; in particular, children do. Something must be wrong. I wish to argue that the frame problem arises from a fundamental presupposition about the nature of representation -- a false presupposition. Yet, it is a presupposition that dominates contemporary developmental psychology (and psychology more broadly, and cognitive science, artificial intelligence, philosophy of mind, and so on). In particular, I will offer an alternative model of the nature of representation within which the frame problem does not arise -- within which such unboundedness is natural. (shrink)

Research Ethics Committees (RECs) play a critical gatekeeping role in clinical trials. This role is meant to ensure that only those trials that meet certain ethical thresholds proceed through their gate. Two of these thresholds are that the potential benefits of trials are reasonable in relation to risks and that trials are capable of producing a requisite amount of social value. While one ought not expect perfect execution by RECs of their gatekeeping role, one should expect routine success in it. (...) This article reviews a range of evidence showing that substantial numbers of ethically tainted trials are receiving REC approvals. Many of the trials are early phase trials that evidence shows have benefits that may not be reasonable compared with their risks and many others are later trials that evidence shows may lack sufficient social value. The evidence pertains to such matters as methodologically inadequate preclinical studies incapable of supporting the inferences that REC members must make about the prospects for potential benefit needed to offset the risks in early phase trials and sponsorship bias that can cause improperly designed, conducted, analysed and reported later phase trials. The analysis of the evidence makes clear that REC practices need to be strengthened if they are to adequately fulfil their gatekeeping role. The article also explores options that RECs could use in order to improve their gatekeeping function. (shrink)

The rapid, recent emergence of new medical knowledge models has engendered a dizzying number of new medical initiatives, programs and approaches. Fields such as evidence-based medicine and translational medicine all promise a renewed relationship between knowledge and medicine. The question for philosophy and other fields has been whether these new models actually achieve their promises to bring about better kinds of medical knowledge—a question that compels scholars to analyze each model’s epistemic claims. Yet, these analyses may miss critical components (...) that explain how these models actually work and function. Using the case of translational medicine, this paper suggests that analyses which treat these models as a primarily epistemic interventions miss the way that new approaches are increasingly shaped by specific financial and commercial agendas. Ultimately, social epistemological analyses that are attentive to market forces are required to make sense of emerging bioscientific research models, which are increasingly tethered to or a manifestation of increasingly financialized models of science research and innovation.

Teaching graduate students how to do research can be a challenge for many instructors because "research education" is not an established field of research like other areas of teaching such as mathematics education, nursing education, science education, and statistics education. There are no scholarly journals devoted solely to teaching research methods; these sources are instead scattered across disciplines and journals (e.g., Nurse Researcher, Volume 13, Number 2, 2005; Sociology, Volume 15, Issue 4, 1981; and Scandinavian Journal of Educational Research, (...) Volume 49, Issue 1, 2005). Furthermore, even though research methods courses are a staple in most graduate training programs, instructors were rarely taught how to teach research methods as part of their own graduate programs. Left to their own devices, instructors of research courses must rely on a network of peers, scattered research literature, and much trial-and-error as they develop and improve upon their own research methods courses.

This book includes ten essays that trace the notion of unconcealment as it develops from Heidegger's early writings to his later work, shaping his philosophy of truth, language and history. 'Unconcealment' is the idea that what entities are depends on the conditions that allow them to manifest themselves. This concept, central to Heidegger's work, also applies to worlds in a dual sense: first, a condition of entities manifesting themselves is the existence of a world; and second, worlds themselves are disclosed. (...) The unconcealment or disclosure of a world is the most important historical event, and Heidegger believes there have been a number of quite distinct worlds that have emerged and disappeared in history. Heidegger's thought as a whole can profitably be seen as working out the implications of the original understanding of unconcealment. (shrink)

When it comes to using patient data from the National Health Service for research, we are often told that it is a matter of trust: we need to trust, we need to build trust, we need to restore trust. Various policy papers and reports articulate and develop these ideas and make very important contributions to public dialogue on the trustworthiness of our research institutions. But these documents and policies are apparently constructed with little sustained reflection on the nature of trust (...) and trustworthiness, and therefore are missing important features that matter for how we manage concerns related to trust. We suggest that what we mean by ‘trust’ and ‘trustworthiness’ matters and should affect the policies and guidance that govern data sharing in the NHS. We offer a number of initial, general reflections on the way in which some of these features might affect our approach to principles, policies and strategies that are related to sharing patient data for research. This paper is the outcome of a ‘public ethics’ coproduction activity which involved members of the public and two academic ethicists. Our task was to consider collectively the accounts of trust developed by philosophers as they applied in the context of the NHS and to coproduce an argumentative position relevant to this context.

Fluorescent probe mixtures derived from total cellular messenger RNA (mRNA) hybridize to cognate elements on the array, allowing accurate measurement of the expression of the corresponding genes. Array densities of >1,000 cDNAs per cm2 enable quantitative expression monitoring of a large number of genes in a single hybridization. A (...) two‐color fluorescence detection scheme allows rapid and simultaneous differential expression analysis of independent biological samples. Mass‐produced microarrays provide a new tool for genome expression analysis that may revolutionize genetic dissection, drug discovery and human disease diagnostics. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Schopenhauer's Pessimism and the Unconditioned Good MARK MIGOTTI SCHOPENHAUERTOOK PESSIMISMtO be a profound doctrine that had long been accepted by the majority of humanity, albeit usually in the allegorical form given to it by one or another religious creed. Accordingly, he credited himself, not with the discovery of pessimism, but with the provision of a satisfactory philosophical exposition and defense of its claims. It was, he contended, only within (...) the context of his philosophy, animated by the "single thought" that "the world is the self-knowledge of the will,"' that the ultimate significance of pessimism and the arguments demonstrating its inescapability can be brought to light. If, nevertheless, he sometimes appears to protest too much, to defend pessimism as if it were a striking and novel affair, he would have attributed this to the fact that he was, unfortunately, writing in the midst of one of the most naively optimistic cultures known to world history. 2 The philosophical reception of Schopenhauer's pessimism since the publication of The World as Will and Representation in 1818 would, one suspects, have been taken by him as further evidence of modern Western philosophy's optimistic somnambulance. For while other, comparably fundamental aspects of his thought--for example, his theories of action, of the self, and his criticisms of Kant--have received a welcome amount of fruitful, critical attention, his I would like to thank John Atwell, David Schmidtz, Susan Haack, Rudolf Makkreel and, especially,two anonymous referees, for prompting me to make substantial improvements to an earlier draft of this paper.

Amongst enthusiastic followers it has sometimes been swallowed more or less whole, but from more independent-minded readers it has generally met with disdainful mockery or well-intentioned neglect.3 The aim of this paper is to help rectify' this imbalance. In the first of its four sections, I present an account of Schopenhauerian pessimism that can claim a good measure of textual support, and the essential features of which are found often enough in the secondary literature to warrant calling it the mainstream interpretation.4 In section 2 I show that, as critics have charged, the arguments for pessimism on this interpretation suffer from a pair of fatal ambiguities, and in section 3 I sketch an alternative argument for pessimism, one not so obviously open to the sort of knock-down refutation to which the first argument succumbs. In the paper's final section l explore further the philosophical consequences of this alternative argument for pessimism. 3Gyorg'yLukacs, "Schopenhauer," chapter ~,section 4 of The Destruction of Reason, trans.

It is shown that the probabilistic theories of coherence proposed up to now produce a number of counter-intuitive results. The last section provides some reasons for believing that no probabilistic measure will ever be able to adequately capture coherence. First, there can be no function whose arguments are nothing but tuples of probabilities, and which assigns different values to pairs of propositions {A, B} and {A, C} if A implies both B and C, or their negations, and if P(B)=P(C). (...) But such sets may indeed differ in their degree of coherence. Second, coherence is sensitive to explanatory relations between the propositions in question. Explanation, however, can hardly be captured solely in terms of probability. (shrink)

This article explores the affinities and parallels between Foucault's Nietzschean view of history and models of complexity developed in the physical sciences in the twentieth century. It claims that Foucault's rejection of structuralism and Marxism can be explained as a consequence of his own approach which posits a radical ontology whereby the conception of the totality or whole is reconfigured as an always open, relatively borderless system of infinite interconnections, possibilities and developments. His rejection of Hegelianism, as well as of (...) other enlightenment philosophies, can be understood at one level as a direct response to his rejection of the mechanical atomist, and organicist epistemological world views, based upon a Newtonian conception of a closed universe operating upon the basis of a small number of invariable and universal laws, by which all could be predicted and explained. The idea of a fully determined, closed universe is replaced; and in a way parallel to complexity theories, Foucault's own approach emphasises notions such as self‐organisation and dissipative structures; time as an irreversible, existential dimension; a world of finite resources but with infinite possibilities for articulation, or re‐investment; and characterised by the principles of openness, indeterminism, unpredictability, and uncertainty. The implications of Foucault's type of approach are then explored in relation to identity, creativity, and the uniqueness of the person. The article suggests that within a complexity theory approach many of the old conundrums concerning determinism and creativity, social constructionism and uniqueness, can be overcome. (shrink)

In this paper, I deploy an argument that I have developed in a number of recent papers in the service of three projects. First, I show that the most influential version of legal positivism – that associated with H.L.A. Hart – fails. The argument’s engine is a requirement that a constitutive account of legal facts must meet. According to this rational-relation requirement, it is not enough for a constitutive account of legal facts to specify non-legal facts that modally determine (...) the legal facts. The constitutive determinants of legal facts must provide reasons for the obtaining of the legal facts (in a sense of “reason” that I develop). I show that the Hartian account is unable to meet this requirement. That officials accept a rule of recognition does not by itself constitute a reason why the standards specified in that rule are part of the law of the community. I argue that it is false that understanding the explanatory significance of officials’ acceptance of a rule is part of our reflective understanding of the nature of law. The second project of the paper is to respond to a family of objections that challenge me to explain why normative facts and descriptive facts together are better placed to provide reasons for legal facts than descriptive facts alone. A unifying theme of the objections is that explanations have to stop somewhere; descriptive facts, it is suggested, are no worse a stopping place than normative facts. Third, the paper spells out a consequence of the rational-relation requirement: if an account of what, at the most basic level, determines legal facts is true in any possible legal system, it is true in all possible legal systems. For example, if a Hartian account of legal facts is true in any possible legal system, it is true in all possible legal systems. I use this all-or-nothing result in my critique of a Hartian account, but the result is of interest in its own right. (shrink)

Philosophers from Plato and Augustine to Heidegger, Nozick, and Baudrillard have warned us of the dangers of living on too heavy a diet of illusion and make-believe. But contemporary cultural life provides broader, more attractive opportunities to do so than have existed at any other point in history. The gentle forms of self-deceit that such experiences require of us, and that so many have regarded as ethically unwholesome or psychologically self-destructive, can in fact serve as vital means to political reconciliation, (...) cultural enrichment, and even (a kind of) utopia. -/- The first half of the book provides a highly schematic definition of simulated experience and compares it with some claims about the nature of simulation made by other philosophers about what it is for one thing to be a simulation of another. The author then provides a critical survey of the views of some major authors about the value of certain specific types of simulated experience, mainly in order to point out the many puzzling inconsistencies and ambiguities that their thoughts upon the topic often exhibit. In the second half of the book, the author defends an account of the positive social value of simulated experience and compares his own position to the ideas of a number of utopian political thinkers, as well as to Plato's famous doctrine of the "noble lie." He then makes some tentative practical suggestions about how a proper appreciation of the value of simulated experience might influence public policy decisions about such matters as the justification of taxation, paternalistic "choice management," and governmental transparency.

In Book I, part iv, section 2 of the Treatise, "Of scepticism with regard to the senses," Hume presents two different answers to the question of how we come to believe in the continued existence of unperceived objects. He rejects his first answer shortly after its formulation, and the remainder of the section articulates an alternative account of the development of the belief. The account that Hume adopts, however, is susceptible to a number of insurmountable objections, which motivates a (...) reassessment of his original proposal. This paper defends a version of Hume's initial explanation of the belief in continued existence and examines some of its philosophical implications. (shrink)

Integrated assessment models (IAMs) of climate and the economy provide estimates of the social cost of carbon and inform climate policy. With the Nested Inequalities Climate Economy model (NICE) (Dennig et al. PNAS 112:15,827–15,832, 2015), which is based on Nordhaus’s Regional Integrated Model of Climate and the Economy (RICE), but also includes inequalities within regions, we investigate the comparative importance of several factors—namely, time preference, inequality aversion, intraregional inequalities in the distribution of both damage and mitigation cost and the damage (...) function. We do so by computing optimal carbon price trajectories that arise from the wide variety of combinations that are possible given the prevailing range of disagreement over each factor. This provides answers to a number of questions, including Thomas Schelling’s conjecture that properly accounting for inequalities could lead the inequality aversion parameter to have an effect opposite to what is suggested by the Ramsey equation.
