According to the variety of evidence thesis items of evidence from independent lines of investigation are more confirmatory, ceteris paribus, than, for example, replications of analogous studies. This thesis is known to fail (Bovens and Hartmann; Claveau). However, the results obtained by Bovens and Hartmann only concern instruments whose evidence is either fully random or perfectly reliable; instead, for Claveau, unreliability is modelled as deterministic bias. In both cases, the unreliable instrument delivers totally irrelevant information. We present a model that (...) formalizes both reliability and unreliability differently. Our instruments either are reliable, but affected by random error, or are biased but not deterministically so.Bovens and Hartmann’s results are counter-intuitive in that in their model a long series of consistent reports from the same instrument does not raise suspicion of ‘too-good-to-be-true’ evidence. This happens precisely because they contemplate neither the role of systematic bias, nor unavoidable random error of reliable instruments. In our model, the variety of evidence thesis fails as well, but the area of failure is considerably smaller than for Bovens and Hartmann and Claveau, and holds for (the majority of) realistic cases (that is, where biased instruments are very biased). The essential mechanism that triggers variety of evidence thesis failure is the rate of false to true positives for the two kinds of instruments. Our emphasis is on modelling beliefs about sources of knowledge and their role in hypothesis confirmation in interaction with dimensions of evidence, such as variety and consistency. (shrink)

The problem discussed here is to find a basis for a uniform treatment of the relation between pronouns and their antecedents, taking into account both linguists' and philosophers' approaches. The two main candidates would appear to be the linguists' notion of coreference and the philosophers' notion of pronouns as variables. The notion of coreference can be extended to many but not all cases where the antecedent is non-referential. The pronouns-as-variables approach appears to come closer to full generality, but there are (...) some examples of pronouns of laziness which appear to resist either of the two approaches. (shrink)

Understanding what numbers are means knowing several things. It means knowing how counting relates to numbers (called the cardinal principle or cardinality); it means knowing that each number is generated by adding one to the previous number (called the successor function or succession), and it means knowing that all and only sets whose members can be placed in one-to-one correspondence have the same number of items (called exact equality or equinumerosity). A previous study (Sarnecka & Carey, 2008) linked children's understanding (...) of cardinality to their understanding of succession for the numbers five and six. This study investigates the link between cardinality and equinumerosity for these numbers, finding that children either understand both cardinality and equinumerosity or they understand neither. This suggests that cardinality and equinumerosity (along with succession) are interrelated facets of the concepts five and six, the acquisition of which is an important conceptual achievement of early childhood.

Philosophical discussions have critically analysed the methodological pitfalls and epistemological implications of evidence assessment in medicine, however they have mainly focused on evidence of treatment efficacy. Most of this work is devoted to statistical methods of causal inference with a special attention to the privileged role assigned to randomized controlled trials (RCTs) in evidence based medicine. Regardless of whether the RCT’s privilege holds for efficacy assessment, it is nevertheless important to make a distinction between causal inference of intended and unintended (...) effects, in that the unknowns at stake are heterogonous in the two contexts. However, although “lower level” evidence is increasingly acknowledged to be a valid source of information contributory to assessing the risk profile of medications on theoretical or empirical grounds, current practices have difficulty in assigning a precise epistemic status to this kind of evidence because they are more or less implicitly parasitic on the (statistical) methods developed to test drug efficacy. My thesis is that (1) “lower level” evidence is justified on distinct grounds and at different conditions depending on the different epistemologies which one wishes to endorse, in that each impose different constraints on the methods we adopt to collect and evaluate evidence; (2) such constraints ought to be understood to be different in the case of evidence for risk versus benefit assessment for a series of reasons which I will illustrate on the basis of the recent debate on the causal association between acetaminophen (a.k.a. paracetamol) and asthma.

Elementary set theory accustoms the students to mathematical abstraction, includes the standard constructions of relations, functions, and orderings, and leads to a discussion of the various orders of infinity. The material on logic covers not only the standard statement logic and first-order predicate logic but includes an introduction to formal systems, axiomatization, and model theory. The section on algebra is presented with an emphasis on lattices as well as Boolean and Heyting algebras. Background for recent research in natural language semantics (...) includes sections on lambda-abstraction and generalized quantifiers. Chapters on automata theory and formal languages contain a discussion of languages between context-free and context-sensitive and form the background for much current work in syntactic theory and computational linguistics. The many exercises not only reinforce basic skills but offer an entry to linguistic applications of mathematical concepts. For upper-level undergraduate students and graduate students in theoretical linguistics, computer-science students with interests in computational linguistics, logic programming and artificial intelligence, mathematicians and logicians with interests in linguistics and the semantics of natural language.

Formal semantics is an approach to SEMANTICS1, the study of meaning, with roots in logic, the philosophy of language, and linguistics, and since the 1980’s a core area of linguistic theory. Characteristics of formal semantics to be treated in this article include the following: Formal semanticists treat meaning as mind-independent (though abstract), contrasting with the view of meanings as concepts “in the head” (see I-LANGUAGE AND E-LANGUAGE and MEANING EXTERNALISM AND INTERNALISM); formal semanticists distinguish semantics from knowledge of semantics (Lewis (...) 1975, Cresswell 1978), which has consequences for the notion of semantic COMPETENCE. A central part of the meaning of a sentence on this approach is its TRUTH CONDITIONS, and most although not all formal semantics is model-theoretic, relating linguistic expressions to model-theoretically constructed semantic values cast in terms of truth, REFERENCE, and possible worlds. This sets formal semantics apart from approaches which view semantics as relating a sentence just to a representation on another linguistic “level” (LOGICAL FORM) or a representation in an innate LANGUAGE OF THOUGHT. The formal semanticist could accept such representations as an aspect of semantics but would insist on asking what the model-theoretic semantic interpretation of the given representationlanguage is (Lewis 1970). Formal semantics is centrally concerned with COMPOSITIONALITY at the SYNTAX-SEMANTICS INTERFACE, how the meanings of larger constituents are built up from the meanings of their parts on the basis of their syntactic structure, and with the relation between compositional SENTENCE MEANING and meaning in discourse.

Formal semantics and pragmatics as they have developed since the late 1960's have been shaped by fruitful interdisciplinary collaboration among linguists, philosophers, and logicians, among others, and in turn have had noticeable effects on developments in syntax, philosophy of language, computational linguistics, and cognitive science.In this paper I describe the environment in which formal semantics was born and took root, highlighting the differences in ways of thinking about natural language semantics in linguistics and in philosophy and logic. With Montague as (...) a central but not solo player in the story, I reflect on crucial developments in the 1960's and 70's in linguistics and philosophy, and the growth of formal semantics and formal pragmatics from there. I discuss innovations, key players, and leading ideas that shaped the development of formal semantics and its relation to syntax, to pragmatics, and to the philosophy of language in its early years, and some central aspects of its early impact on those fields.

The problem of collecting, analyzing and evaluating evidence on adverse drug reactions (ADRs) is an example of the more general class of epistemological problems related to scientific inference and prediction, as well as a central problem of the health-care practice. Philosophical discussions have critically analysed the methodological pitfalls and epistemological implications of evidence assessment in medicine, however they have mainly focused on evidence of treatment efficacy. Most of this work is devoted to statistical methods of causal inference with a special (...) attention to the privileged role assigned to randomized controlled trials in Evidence Based Medicine. Regardless of whether the RCT’s privilege holds for efficacy assessment, it is nevertheless important to make a distinction between causal inference of intended and unintended effects, in that the unknowns at stake are heterogonous in the two contexts. This point has been emphasized by epidemiologists in the last decade. Their main focus is methodological, and regards the fact that bias and confounding do not affect studies on intended and unintended effects in the same way. However, deeper concerns ground the intuition for such a distinction; these are related to the constraints which we impose on evidence and their epistemological justification. My thesis is that such constraints ought to be understood to be different in the case of evidence for risk vs. benefit assessment. I present the recent debate on the causal association between acetaminophen and asthma in order to illustrate the point at issue. (shrink)

The goal of this paper is to argue for the fruitfulness for linguistic theory of an approach to semantics that has been developed primarily by logicians and philosophers. That the theory of possible worlds semantics has been extremely fruitful for logic and philosophy is widely if not universally accepted, and I will not try to convince remaining skeptics on that score. But the goals of linguistics are sufficiently different from those of philosophy and logic that there are independent and highly (...) reasonable grounds for skepticism about the appropriateness of such a theory for linguistics, and I will address what seem to me the most important of these in addition to offering positive evidence in favor of such an approach to semantics.

I argue for the possibility of posthumous harm based on an account of the harm of murder. I start with the deep-seated intuition that when someone is murdered he (or she) is harmed (over and above the pain of injury or dying), and argue that Feinberg's account that assumes that harm is an invasion of an interest cannot plausibly accommodate this intuition. I propose a new account of the harm of murder: it is an irreversible loss of functions necessary for (...) worthwhile existence. I suggest a (partial) loss analysis of harm in general, and then go on to apply it to posthumous harm and defend the idea that there can be posthumous losses. (shrink)

_Retrieving Political Emotion _engages the reader in an excursion through our ancient Greek heritage to recover a concept of emotion useful for enriching political philosophy today. Focusing on _thumos_, Barbara Koziak reveals misinterpretations of the concept that have hampered recognition of its possibilities for normative theory. Then, drawing especially on Aristotle's construal of it as a general capacity for emotion and relating this to contemporary multidisciplinary work on emotion, she reformulates _thumos_ to provide a more adequate theory of political (...) emotion, as an antidote to the modern fixation on rational self-interest as the key to explaining political behavior. The book proceeds by recounting the way _thumos_ is used in Homer's _Iliad_ and Plato's _Republic_ and then showing how, while borrowing from both, Aristotle went substantially beyond them. From the _Nicomachean Ethics and Politics_ we can see the activity of _thumos_—how a person with good _thumos_ acts and through which institutions. Through the _Poetics_ we observe the characteristic disposition of _thumos_—what patterns and objects typify a person's emotional capacity in the best regime. Her reconstructed Aristotelian theory of political emotion allows Koziak in the concluding chapter to show how it can help us better understand political behavior today, as manifested in recent congressional debates on welfare reform, and through constructive engagement with feminist thinking on the "ethics of care" lead political theory to pay more attention to the importance of passions in political life.

How should biological behaviour be modelled? A relatively new approach is to investigate problems in neuroethology by building physical robot models of biological sensorimotor systems. The explication and justification of this approach are here placed within a framework for describing and comparing models in the behavioural and biological sciences. First, simulation models – the representation of a hypothesis about a target system – are distinguished from several other relationships also termed “modelling” in discussions of scientific explanation. Seven dimensions on which (...) simulation models can differ are defined and distinctions between them discussed: 1. Relevance: whether the model tests and generates hypotheses applicable to biology. 2. Level: the elemental units of the model in the hierarchy from atoms to societies. 3. Generality: the range of biological systems the model can represent. 4. Abstraction: the complexity, relative to the target, or amount of detail included in the model. 5. Structural accuracy: how well the model represents the actual mechanisms underlying the behaviour. 6. Performance match: to what extent the model behaviour matches the target behaviour. 7. Medium: the physical basis by which the model is implemented. No specific position in the space of models thus defined is the only correct one, but a good modelling methodology should be explicit about its position and the justification for that position. It is argued that in building robot models biological relevance is more effective than loose biological inspiration; multiple levels can be integrated; that generality cannot be assumed but might emerge from studying specific instances; abstraction is better done by simplification than idealisation; accuracy can be approached through iterations of complete systems; that the model should be able to match and predict target behaviour; and that a physical medium can have significant advantages. These arguments reflect the view that biological behaviour needs to be studied and modelled in context, that is, in terms of the real problems faced by real animals in real environments. Key Words: animal behaviour; levels; models; neuroethology; realism; robotics; simulation. (shrink)

The paper considers the legal tools that have been developed in German pharmaceutical regulation as a result of the precautionary attitude inaugurated by the Contergan decision. These tools are the notion of “well-founded suspicion”, which attenuates the requirements for safety intervention by relaxing the requirement of a proved causal connection between danger and source, and the introduction of the reversal of proof burden in liability norms. The paper focuses on the first and proposes seeing the precautionary principle as an instance (...) of the requirement that one should maximise expected utility. In order to maximise expected utility certain probabilities are required and it is argued that objective Bayesianism offers the most plausible means to determine the optimal decision in cases where evidence supports diverging choices.

In a provocative book, Andrew Carstairs- McCarthy argues that the apparently universal distinction in human languages between sentences and noun phrases cannot be assumed to be inevitable for languages with the expressive power of human languages, but needs explaining. His work suggests, but does not explicitly state, that there is also no conceptual necessity for the distinction between basic types e and t, a distinction argued for by Frege and carried into formal semantics through the work of Montague. Pragmatic distinctions (...) among various kinds of speech acts, including asserting, questioning, commanding, and pointing things out are assumed in Carstairs- McCarthy ’s work, as are expressions of functional types; what is questioned is whether a syntacticized sentence-NP distinction is essential.

: The main threads of Emmanuel Levinas's theory of ethics, developed in his philosophical works, Totality and Infinity (1969), and Otherwise than Being or Beyond Essence (1998), instruct that ethics require transcendence of being and nature, which he describes in terms of a transcendence of animality to the human. This apparent devaluation of the nonhuman would seem to preclude the development of Levinasian environmental ethics. However, a deconstructive reading of Levinas recognizes a subtext that interrupts the main threads of his (...) argument running against the inclusion of nonhuman others in ethics. Through a critical reconstructive reading of Levinas, I develop an ethic extraneous to Levinas's transcendent ethics, an ethic outside his "otherwise than being.". (shrink)

A lengthy debate in the philosophy of the cognitive sciences has turned on whether the phenomenon known as ‘systematicity’ of language and thought shows that connectionist explanatory aspirations are misguided. We investigate the issue of just which phenomenon ‘systematicity’ is supposed to be. The much-rehearsed examples always suggest that being systematic has something to do with ways in which some parts of expressions in natural languages (and, more conjecturally, some parts of thoughts) can be substituted for others without altering well-formedness. (...) We show that under one construal this yields a grossly weak claim that is not just compatible with a narrow version of associationist psychology but essentially coincides with a formalization of its descriptive power. Under another construal we get a claim (apparently unintended) that requires natural languages to fall within the context-free class, a claim that most linguists regard as too strong. Looking more closely at this proposed reconstruction of systematicity leads us to endorse, with further illustrations, the suggestion of Johnson (2004) that systematicity as a matter of substitutability of co-categorial constituents for one another does not appearto hold of natural languages at all. The appeal of the ill-delineated notion of systematicity may lie in the fact that within certain subclasses of lexical items mutual intersubstitutability does seem to hold, and theexplanation for that lies in a limitation on human memory: we simply cannot learn separate privileges of syntactic distribution for all of the huge number of words and phrases that we know.

Dworkin's theoretical disagreement argument, developed in Law's Empire, is presented in that work as the motivator for his interpretive account of law. Like Dworkin's earlier arguments critical of legal positivism, the argument from theoretical disagreement has generated a lively exchange with legal positivists. It has motivated three of them to develop innovative positivist positions. In its original guise, the argument from theoretical disagreement is presented as ‘the semantic sting argument’. However, the argument from theoretical disagreement has more than one version. (...) This article briefly discusses two versions and the leading replies to them, then focuses on the most influential version, directed at Hartian positivism. The article surveys the leading positivist rejoinders to the recast version, indicating key Dworkinian replies or assessing the strength of these rejoinders, and concludes with a rejoinder of its own, making a new case that the argument from theoretical disagreement isn't fatal for Hartian legal positivism.

A familiar jurisprudential view is that a judicial decision functions as a legal precedent by laying down a rule and that the content of this rule is set by officials. Precedents can be followed only by acting in accordance with this rule. This view is mistaken on all counts. A judicial decision functions as a precedent by being an example. At its best, it is an example both for officials and for a target population. Even precedents outside of law function (...) as examples when they have conduct-guiding significance. Examples may be rule-like in their scope, but need not be. Their import is independent of their justification; this point has implications for coherence theories of precedent meaning. The content and scope of a legal decision’s extension is not set exclusively by officials. It is socially set and depends upon social salience. (shrink)

Artificial insemination and other fertilization techniques are today considered central to the history of reproductive medicine. The medical treatment of infertile couples, however, constitutes just a small part of the whole story of artificial fertilization. Lazzaro Spallanzani in particular, said to have been the inventor of artificial insemination, did not develop this method for medical purposes. He belonged to a generation of naturalists to whom artificial insemination was part of a heterogeneous series of investigations that were undertaken to explore the (...) natural history of animal generation. Questions concerning conception, the role of the gametes, the definition of species, the production of hybrids or livestock breeding were all included in these investigations. Thus, no one strain of thought, nor single set of ideas or interests, entirely shaped the development of artificial fertilization. (shrink)

The paper addresses charges of risk and loss aversion as well as of irrationality directed against the precautionary principle, by providing an epistemic analysis of its specific role in the safety law system. In particular, I contend that: 1) risk aversion is not a form of irrational or biased behaviour; 2) both risk and loss aversion regard the form of the utility function, whereas PP rather regards the information on which to base the decision; 3) thus PP has formally nothing (...) to do with risk or loss aversion but rather with risk awareness; 4) PP removes a fictional construct in the legal system, according to which any hazard should be ignored and denied until it is scientifically proven; 5) the quandary originates in the tension between current methods of evidence evaluation, and the logic underlying PP which demands for a probabilistic epistemology.

Everyone agrees that law is a constituent of social reality. Law seems to be a system by which conduct is governed and guided. Its usefulness consists, in part, on its ability to govern and guide conduct in its characteristic way. If laws guides the conduct of lay law subjects, then it must be (really) possible for the content of the laws governing their conduct to be known by them under standard social conditions. Moreover, if some degree of efficacy in guiding (...) and governing the conduct of lay law subjects is an existence condition for a legal system, then in existing legal systems enough of the content of directive law is epistemically accessed by enough law subjects so that they can apply it to their situations and correctly determine the act-tokens required of them. In this chapter, I argue that these modest epistemic reflections have important implications for a theory of legal content that have been largely ignored. Holistic theories of legal content, such as Greenberg’s and Dworkin’s, are inconsistent with an adequate account of epistemic access. After demonstrating the same problem in two mainstream non-holistic theories of legal content -- the view that legal content is set entirely by official interpretive conventions, and the view that legal content is set entirely by official intentions – I propose a theory of legal content that meets the epistemic access challenge. On my approach, law is, at its core, centered upon the understandings of law subjects. (This view is meant to exempt constitutional provisions.) More precisely, the legal content of statutes and judicial decisions is built around, and preserves, a core of understandings and meaning-assignments that is the province of anyone with sufficient linguistic ability and relevant socialization. The details of this view are, roughly: (1) in the case of judicial decisions in a common law system, the social salience of the example the decision sets concerning behavior sets the default legal content; (2) in the case of statutory directives, the set of socially salient applications (behavior in situations) sets the default legal content. I say `default’ because my account of legal content is a two-stage account beginning with the default content and permitting a second stage in which considerations from other sources can operate on the default. Yet if a certain amount of efficacy in guiding lay law subjects’ behavior is a requirement for the existence of a legal system, there must be a core of legal content undistorted from its default social salience by a second stage operation. There is and must be a `law of the street’. -/- . (shrink)

In the special section ‘Body Hacking: Self-Made Cyborgs and Visions of Transhuman Corporeality’, attention is drawn to cyborgism, a set of cultural and very personal practices of experimentation with the human body that often take place outside the confines of institutionalised technoscience.

They consider the (...) body a highly malleable material, a transformable, improvable, augmentable entity. The collection of papers in this special section encompasses first-hand accounts of cyborg practices as well as intellectual reflections on their implications. (shrink)

This essay develops its idiosyncrasy by concentrating primarily on the trend of body hacking. The practitioners, self-defined as body hackers, self-made cyborgs or grinders, work in different ways to develop functional and physiological modifications through the contributions of technology. Their goal is to develop by themselves an empirically man-technique fusion. These dynamic “scientific” subcultures are producing astonishing innovations. From pocket-sized kits that sample human DNA, microchip implants that keep tabs on our internal organs, blood sugar levels or moods, and even (...) 3D printers that produce tailored hip replacements, the technical innovations of the body hacking trend are beginning to filter into mainstream use, and the repertoire increases every day. These physical transformations with intersecting techniques actively challenge long-held normative beliefs about what bodies do, what they should look like and how they should behave. They provide an alternative discourse on man’s correlation with the world and its biocenosis. Sculpting oneself has become an existential data. Medical technoscience crystallizes the effectiveness of new powers over the organism. Scientific temptation to recreate and enhance the human according to its normative principles has brought up experimental practices that have become the edge of a radical activism operating in the core of western societies, which will be the theme of this paper.

This paper will examine the effects of gender, age, work experience, academic status and legality on certain ethical decisions. Six scenarios representing ethical dilemmas were presented to both undergraduate and MBA students in an attempt to determine if various demographic factors influenced ethical decision making. While some past studies have suggested that gender has an important effect on ethical decision making, this study does not completely support this conclusion and suggests that age and/or length of work experience should be included (...) in any study of ethical decision making.The legality of the decisions was determined and compared to the reason given by the students for their decisions. In some cases the choice made by a majority of the students was not the one that was supported by the legal authorities which suggests that there may be conflicts between the ethical system of the respondents and the behavior expected of them by society.

Risk communication has been generally categorized as a warning act, which is performed in order to prevent or minimize risk. On the other side, risk analysis has also underscored the role played by information in reducing uncertainty about risk. In both approaches the safety aspects related to the protection of the right to health are on focus. However, it seems that there are cases where a risk cannot possibly be avoided or uncertainty reduced, this is for instance valid for the (...) declaration of side effects associated with pharmaceutical products or when a decision about drug approval or retirement must be delivered on the available evidence. In these cases, risk communication seems to accomplish other tasks than preventing risk or reducing uncertainty. The present paper analyzes the legal instruments which have been developed in order to control and manage the risks related to drugs – such as the notion of “development risk” or “residual risk” – and relates them to different kinds of uncertainty. These are conceptualized as epistemic, ecological, metric, ethical, and stochastic, depending on their nature. By referring to this taxonomy, different functions of pharmaceutical risk communication are identified and connected with the legal tools of uncertainty management. The purpose is to distinguish the different functions of risk communication and make explicit their different legal nature and implications. (shrink)
