In this important book, a distinguished legal scholar examines how the legal culture and institutions in Anglo-American countries affect the way in which evidence is gathered, sifted, and presented to the courts.

"Philosophical Foundations of Evidence Law presents a cross-disciplinary overview of the core issues in the theory and methodology of adjudicative evidence and factfinding, assembling the major philosophical and interdisciplinary insights that define evidence theory, as related to law, in a single book. The volume presents contemporary debates on truth, knowledge, rational beliefs, proof, argumentation, explanation, coherence, probability, economics, psychology, bias, gender, and race. It covers different theoretical approaches to legal evidence, including the Bayesian approach, scenario theory, (...) and inference to the best explanation. The volume’s contributions come from scholars spread across three continents and twelve different countries, whose common interest is evidence theory as related to law"-- from publisher's website.

This article reviews contemporary response to several contrasting strands of recent empirical work. It begins with discussing the scope and rationale of evidence law. Experimental studies on eyewitness memory and testimony illustrate the potential value of empirical studies to the practice of investigations, prosecutions, and appeals. This article discusses several lines of empirical inquiry employing diverse methodologies, experiments, surveys, and approaches and reviews their limitations, and implications and significance for the understanding and practice of law. Many of the contributions (...) from empirical legal studies are provisional and their precise value for practice is uncertain or ambiguous, but they raise important issues worthy of serious consideration. By identifying problems with eyewitness evidence and the limitations of many of the forensic sciences, and in many other ways, empirical and experimental studies have substantially outpaced legal experience. Indifference to empirical legal study is likely to reduce the social legitimacy of legal institutions. (shrink)

This is the first book to systematically examine the underlying theory of evidence in Anglo-American legal systems. Stein develops a detailed and innovative theory which sets aside the traditional vision of evidence law as facilitating the discovery of the truth. Combining probability theory, epistemology, economic analysis, and moral philosophy, he argues instead that the fundamental purpose of evidence law is to apportion the risk of error in conditions of uncertainty.

This book examines the legal and moral theory behind the law of evidence and proof, arguing that only by exploring the nature of responsibility in fact-finding can the role and purpose of much of the law be fully understood. Ho argues that the court must not only find the truth to do justice, it must do justice in finding the truth.

The vast majority of Biblical historians believe there is evidence sufficient to place Jesus’ existence beyond reasonable doubt. Many believe the New Testamentdocuments alone suffice firmly to establish Jesus as an actual, historical figure. I question these views. In particular, I argue (i) that the three most popular criteria by which various non-miraculous New Testament claims made about Jesus are supposedly corroborated are not sufficient, either singly or jointly, to place his existence beyond reasonable doubt, and (ii) that a (...) prima facie plausible principle concerning how evidence should be assessed—a principle I call the contamination principle—entails that, given the large proportion of uncorroborated miracle claims made about Jesus in the New Testament documents, we should, in the absence of good independent evidence for an historical Jesus, remain sceptical about his existence.

We all know that we have and are our bodies. But might it be possible to leave this common place? In the present article we try to do this by attending to the way we do our bodies. The site where we look for such action is that of handling the hypoglycaemias that sometimes happen to people with diabetes. In this site it appears that the body, active in measuring, feeling and countering hypoglycaemias is not a bounded whole: its boundaries (...) leak. Bits and pieces of the outside get incorporated within the active body; while the centre of some bodily activities is beyond the skin. The body thus enacted is not self-evidently coherent either. There are tensions between the body’s organs; between the control under which we put our bodies and the erratic character of their behaviour; and between the various needs and desires single bodies somehow try to combine. Thus to say that a body is a whole, or so we conclude, skips over a lot of work. One does not hang together as a matter of course: keeping oneself together is something the embodied person needs to do. The person who fails to do so dies. (shrink)

This volume presents cutting edge research by many of the leading researchers in the field of religious epistemology, a field that has seen major development in recent years. This book attempts to answer the questions of: how reasonable is belief in God? Can a good evidential case be made either for the existence of God, or against the existence of God? Does the existence of enormous suffering, or religious disagreement, provide significant evidence against the existence of God? How might (...) we best come to know God? What's required for religious belief to qualify as rational? All of the papers included in this volume aim to be accessible to the interested layperson. (shrink)

This paper asks whether geographically localised, or ‘hyperlocal’, uses of Twitter succeed in creating peer-to-peer neighbourhood networks or simply act as broadcast media at a reduced scale. Literature drawn from the smart cities discourse and from a UK research project into hyperlocal media, respectively, take on these two opposing interpretations. Evidence gathered in the case study presented here is consistent with the latter, and on this basis we criticise the notion that hyperlocal social media can be seen as a (...) community in itself. We demonstrate this by creating a network map of Twitter followers of a popular hyperlocal blog in Brockley, southeast London. We describe various attributes of this network including its average degree and clustering coefficient to suggest that a small and highly connected cluster of visible local entities such as businesses form a clique at the centre of this network, with individual residents following these but not one another. We then plot the locations of these entities and demonstrate that sub-communities in the network are formed due to close geographical proximity between smaller sets of businesses. These observations are illustrated with qualitative evidence from interviews with users who suggest instead that rather than being connected to one another they benefit from what has been described as ‘neighbourhood storytelling’. Despite the limitations of working with Twitter data, we propose that this multi-modal approach offers a valuable way to investigate the experience of using social media as a communication tool in urban neighbourhoods.

Here's an overview of one of the more ingenious attempts to criticize religious belief. Antony Flew argues that if the religious won't allow anything to count as evidence against what they believe, then they don't actually believe anything. The religious aren't making false claims; rather, they're not making any claims at all.

Is truth in the law just plain truth - or something sui generis? Is a trial a search for truth? Do adversarial procedures and exclusionary rules of evidence enable, or impede, the accurate determination of factual issues? Can degrees of proof be identified with mathematical probabilities? What role can statistical evidence properly play? How can courts best handle the scientific testimony on which cases sometimes turn? How are they to distinguish reliable scientific testimony from unreliable hokum? These interdisciplinary (...) essays explore such questions about science, proof, and truth in the law. With her characteristic clarity and verve, Haack brings her original and distinctive work in theory of knowledge and philosophy of science to bear on real-life legal issues. She includes detailed analyses of a wide variety of cases and lucid summaries of relevant scientific work, of the many roles of the scientific peer-review system, and of relevant legal developments.

Drawing on recently published correspondence as well as on a survey of Polish and international philosophical activity published in 1937 and details concerning the publisher and bookseller Aleksander Mazzucato, I provide evidence that, contrary to some recent assertions (but in line with older bibliographical entries), Tarski's ‘Der Wahrheitsbegriff in den formalisierten Sprachen’ was not published in journal form until 1936, although preprints, lacking two corrections and a small addendum, were likely available in the late months of 1935.

Despite the long history of beliefs about the therapeutic properties of work for people with mental ill health, rarely has therapeutic work itself been a focus for historical analysis. In this article, the development of a therapeutic work ethic (1813—1979) is presented, drawing particular attention to the changing character and quality of beliefs about therapeutic work throughout time. From hospital factories to radical ‘antipsychiatric’ communities, the article reveals the myriad forms of activities that have variously been considered fit work for (...) people with mental health problems. While popular stereotypes of basket-weaving paint a hapless portrait of institutional work, a more nuanced reading of therapeutic work and its political and philosophical commitments is advanced. The article concludes by arguing that the non-linear and inherently contested development of therapeutic work is less the effect of paradigmatic shifts within the therapeutic professions, but rather evidence of a broader human struggle with work.

This paper analyses the Verlagsanzeige of the humanist, mathematician, astronomer and publisher Johannes Regiomontanus. How is humanism expressed in this famous document from German early printing and what is its relationship to philosophy? The article shows that Regiomontanus advocated a special form of humanism that went beyond the standard humanism that he valued, with ‘truth’ as its most important aspect. From the epistemological perspective of the history of philosophy in Regiomontanus’s publishing programme, the ‘truth’ of mathematics is seen, analogous to (...) some predecessors, as a paradigm of programmatic testimony. The integration of philosophy is evident in this, as in another specified way as well. (shrink)

The epistemological analysis offered in this paper reveals that a combination of pieces of evidence, none of them sufficient by itself to warrant a causal conclusion to the legally required degree of proof, may do so jointly. The legal analysis offered here, interlocking with this, reveals that Daubert’s requirement that courts screen each item of scientific expert testimony for reliability can actually impede the process of arriving at the conclusion most warranted by the evidence proffered.

We argue that legal argumentation, as the subject matter as well as a special subfield of Argumentation Studies (AS), has to be examined by making skilled use of the full panoply of tools such as argumentation and story schemes which are at the forefront of current work in AS. In reviewing the literature, we make explicit our own methodological choices (particularly regarding the place of normative deliberation in practical reasoning) and then illustrate the implications of such an approach through the (...) analysis of a case study in the English law of evidence. We argue that a clear distinction must be drawn between practical argumentation and stories. Because of the institutional separation between legal judgment and fact-finding in common-law jury trials, we argue for the combination of argument and story-based analysis. (shrink)

Recent work in artificial intelligence has increasingly turned to argumentation as a rich, interdisciplinary area of research that can provide new methods related to evidence and reasoning in the area of law. Douglas Walton provides an introduction to basic concepts, tools and methods in argumentation theory and artificial intelligence as applied to the analysis and evaluation of witness testimony. He shows how witness testimony is by its nature inherently fallible and sometimes subject to disastrous failures. At the same time (...) such testimony can provide evidence that is not only necessary but inherently reasonable for logically guiding legal experts to accept or reject a claim. Walton shows how to overcome the traditional disdain for witness testimony as a type of evidence shown by logical positivists, and the views of trial sceptics who doubt that trial rules deal with witness testimony in a way that yields a rational decision-making process.

During the COVID-19 pandemic, the race to find an effective vaccine or treatment saw an ‘extraordinary number’ of clinical trials being conducted. While there were some key success stories, not all trials produced results that informed patient care. There was a significant amount of waste in clinical research during the pandemic which is said to have hampered an evidence-based response. Conducting trials which could have been predicted to fail to answer the research question (e.g. because they are not large (...) enough to provide a definitive result) is not only a waste of resources but also a breach of research participants’ trust and a violation of research ethics. The issues seen in COVID-19 clinical trials are symptomatic of a wider trial design crisis where many trials do not provide informative results. This paper examines the roles of key stakeholders in delivering ethical and informative trials and whether guidance published by ‘The Good Clinical Trials Collaborative’ could be used to align key stakeholder groups and enable a joined-up approach to improve clinical trial design.

In Mengzi 6A4, Gaozi states that “yì 義 (propriety, rightness) is external, not internal.” In 6A5, Meng Jizi says of yì that “...it is on the external, not from the internal.” Their defenses are met with Mengzi’s resistance. What does he perceive and resist in these statements? Focusing on several key passages, I compare six promising interpretations. 6A4 and a relevant part of 2A2 can be rendered comparably sensible under each of the six. However, what Gaozi says in 6A1 clearly (...) is evidence to Mengzi that, of the six views, Gaozi holds three although he does not convey them in his statement. As for Meng Jiz’s defense of his statement, Meng Jizi cites a special occasion where one is required to act one way even though one would feel a different way. Mengzi’s response has been traditionally interpreted as boiling down to a dissenting opinion about empirical psychology, that the agent on that special occasion would in fact feel the same way as they ought to act. But on a more charitable reading, the point Mengzi makes is conceptual: Though the satisfaction of yì may not require that the feeling and the act align perfectly in this case, cases where the alignment obtains are conceptually prior. This not only refutes Meng Jizi’s statement but also enables a more elegant explanation of why the Mengzi rightly has no record of Mengzi affirming that yì is internal. I conclude that 6A5 itself uniquely favors one interpretation, as far as Meng Jizi’s position is concerned: How one feels is irrelevant to whether one satisfies yì. (shrink)

"This work springs from a conviction of the unity of nature, expressed here in a single principle. In its earliest form this conviction was merely the sense of a hidden unity of form in nature, which the intellect had not yet identified. At that stage it had little value, except in creating the need to find a rational justification for the a-rational feeling. Soon I realised that the discovery of a universal form of process was hindered by the intellectual separation (...) of the processes of subjective experience from those of the external world. It was necessary to bring into closer relation the scientific conception of the forms of external nature and the subjective sense of the forms of experience. This in turn led to the recognition that the methods of exact science had paid inadequate attention to the irreversible or one-way character of process, which is unmistakable in the subjective realm, but is also evident in many inorganic and organic processes, such as those do which form is developed. I expressed this view in a sketch of the outlook of the sciences, entitled Archimedes, or the Future of Physics (1927). The next step was the observation that one principle only could account for the development of regular spatial forms: the principle that asymmetry decreases in isolable processes. This concept of one-way process appeared to me to be the most general conception of spatial process conceivable at the present time, so that all other types of process should be capable of being represented as special cases. I called it the Unitary Principle and determined to use it as the basis of a comprehensive scientific method."--The preface. (shrink)

However little that various disciplines in the humanities and social sciences might seem to have in common, they share certain interests in methodological problems relating to evidence, inference, and interpretation. By pursuing these shared interests across divergent topics and fields, the contributors to this book advance our understanding of how such truth-seeking, proof-finding methods work, and of what it means to prove something in a range of contexts. Coedited by William Twining, one of the world's outstanding evidence scholars, (...) and Lain HempsherMonk, a leading political theorist, the volume considers intriguing questions from different realms--Assyriology, theatre iconography, musicology, criminology, the history of ideas and colonial history--as it reveals how particular concepts, lines of questioning, and techniques of reasoning and analysis developed in one context can be fruitfully applied in others.

Informal science learning sites create opportunities for children to learn about science outside of the classroom. This study analyzed children’s learning behaviors in ISLS using video recordings of family visits to a zoo, children’s museum, or aquarium. Furthermore, parent behaviors, features of the exhibits and the presence of an educator were also examined in relation to children’s behaviors. Participants included 63 children and 44 parents in 31 family groups. Results showed that parents’ science questions and explanations were positively related to (...) children observing the exhibit. Parents’ science explanations were also negatively related to children’s science explanations. Furthermore, children were more likely to provide science explanations when the exhibit was not interactive. Lastly there were no differences in children’s behaviors based on whether an educator was present at the exhibit. This study provides further evidence that children’s interactions with others and their environment are important for children’s learning behaviors. (shrink)

In Beck, focus intervention is used as an argument for reducing Hamblin’s semantics for questions to Rooth’s focus semantics. Drawing on novel empirical evidence from Mandarin and English, we argue that this reduction is unwarranted. Maintaining both Hamblin’s original semantics and Rooth’s focus semantics not only allows for a more adequate account for focus intervention in questions, but also correctly predicts that focus intervention is a very general phenomenon caused by interaction of alternatives in different dimensions.

Ever since Jeremy Bentham wrote his scathing critique of the law of evidence, both philosophers and legal scholars have criticized the exclusionary rules of evidence, arguing that formal rules excluding entire classes of evidence for alleged unreliability violate basic epistemological maxims mandating that all relevant evidence be considered. Although particular pieces of evidence might be excluded as unreliable, they argue, it is a mistake to make such judgments for entire categories, as opposed to making them (...) only in the context of particular pieces of evidence offered for specific purposes. This paper challenges these claims, arguing that rule-based exclusions serve similar purposes to those served by rules in rule-consequentialist moral theories, and that, even more importantly, they are entirely consistent with the exclusionary nature of legal rules in general. Indeed, once we see the role that exclusionary rules might serve in legal epistemology, we can see that they might have a role to play in epistemic appraisal more generally. (shrink)

This article sets out to investigate aspects of the uptake of Renaissance law and medicine from some of the logical and natural-philosophical components of the university arts course. Medicine is shown to have a much laxer operative logic than law, reflecting its commitment to the theory of idiosyncrasy as opposed to the demands made upon the law by the need for a uniform application of justice. Symptomatic of the different uptake arc the contrasting meanings of "regulariter" and "generaliter" in the (...) two disciplines. Whereas the law treats the rule as inviolable and the exception as only valid if made explicit in due legal form, medicine is able to conceive of a nature as a field of knowledge broader than that encompassed by its rules of art. Both law and medicine approach evidence. (shrink)

Over several decades, ethics and law have been applied to medical education and practice in a way that reflects the continuation during the twentieth century of the strong distinction between facts and values. We explain the development of applied ethics and applied medical law and report selected results that reflect this applied model from an empirical project examining doctors’ decisions on withdrawing/withholding treatment from patients who lack decision-making capacity. The model is critiqued, and an alternative “constitutive” model is supported on (...) the basis that medicine, medical law, and medical ethics exemplify the inevitable entanglement of facts and values. The model requires that ethics and law be taught across the medical education curriculum and integrated with the basic and clinical sciences and that they be perceived as an integral component of medical evidence and practice. Law, in particular, would rank as equal in normative authority to the relevant clinical scientific “facts” of the case, with graduating doctors having as strong a basic command of each category as the other. The normalization of legal knowledge as part of the clinician’s evidence base to be utilized in practice may provide adequate consolation for clinicians who may initially resent further perceived incursions on their traditional independence and discretion.

Evidence suggests that the incidence of research misconduct is not in decline despite efforts to improve awareness, education and governance mechanisms. Two responses to this problem are favoured: first, the promotion of an agent-centred ethics approach to enhance researchers’ personal responsibility and accountability, and second, a change in research culture to relieve perceived pressures to engage in misconduct. This article discusses the challenges for both responses and explains how normative coherence through values alignment might assist. We argue that research (...) integrity and research ethics convey mixed messages, which are likely to contribute to a form of normative confusion. For the successful adoption of an agent-centred approach, normative coherence is needed between the two. To facilitate normative coherence, we propose that research ethics and research integrity be underpinned by a shared set of moral values that can be enacted via codes and guidelines and imbue research environments. Furthermore, to facilitate culture change, the same normative coherence is necessary at all levels of an institution. Only via values alignment between institutional aims, management, institutional practices and researchers can an ethical culture become truly embedded in research institutions. (shrink)

In recent years, foreign language learning has been proposed as a possible cognitive intervention for older adults. However, the brain network and cognitive functions underlying FLL has remained largely unconfirmed in older adults. In particular, older and younger adults have markedly different cognitive profile—while older adults tend to exhibit decline in most cognitive domains, their semantic memory usually remains intact. As such, older adults may engage the semantic functions to a larger extent than the other cognitive functions traditionally considered the (...) most important. Using anatomical measurements and a cognitive test battery, the present study examined this hypothesis in twenty cognitively normal older adults, who participated in a two-month Italian learning programme. Results showed that the immediate learning success and long-term retention of Italian vocabularies were most consistently predicted by the anatomical measures of the left pars orbitalis and left caudal middle frontal cortex, which are implicated in semantic and episodic memory functions. Convergent evidence was also found based on the pattern of cognitive associations. Our results are consistent with a prominent role of semantic and episodic memory functions in vocabulary learning in older learners. (shrink)

In «Naturalized Epistemology and the Law of Evidence Revisited», the original target article for the various refutations that I comment on here, I revisited through a slightly different lens the subject of the article that I coauthored with Brian Leiter close to twenty years ago. That article has prompted four responses from Professors Pardo, Spellman, Muffato, and Enoch. Professors Pardo and Spellman basically accept the implications of the original article and offer useful but friendly amendments. Prof. Muffato apparently does (...) not want to dispute over my ground and so changes the subject, and in doing so offers a number of interesting points. Only the fourth, Prof. Enoch, has the same doubts about the utility of my original article as I do of the genre that gave rise to it. I can thus be quite brief in discussing professors Pardo, Spellman, and Muffato, but it will take bit more effort to lay out the limits of Prof. Enoch’s analysis. (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.

A noticeable shift in focus has occurred in public discourse from What is our best course of action? to What are the true facts of the situation? At the center of these debates are questions on the proper use of evidence, Legal scholar Schauer offers clarity based on how legal systems grapple with these questions-and by drawing insights from psychology, philosophy, economics, history, and decision theory.

When we hear about a transgression, we may consider whether the perpetrator’s individual circumstances make their transgression more understandable or excusable. Mitigating circumstances may reduce the severity of punishment that is deemed appropriate, both intuitively and legally. But importantly, in courts of public opinion and of law, mitigating information is typically presented only after information about a perpetrator’s transgression. We explore whether this sequence influences the force of mitigating evidence. Specifically, in two studies, we examined whether presenting evidence (...) about a perpetrator’s background before or after evidence of their violation influenced how severely U.S. participants punished perpetrators. In Study 1 (N = 132), evidence about the perpetrator’s mitigating circumstances reduced punishment only when it was presented before evidence about the perpetrator’s violation. Study 2 (N = 316) additionally revealed this moderating effect of presentation order across a variety of premeditated and impulsive violations. These findings are consistent with person-centered theories of punishment and with the Story Model of adjudication. (shrink)

Evidence-based law seeks to make best use of evidence to assess the effectiveness of laws and regulations. The question arises as to how exactly to make best use of evidence. This paper argues that Evidential Pluralism provides an answer to this question and can thus provide philosophical foundations for evidence-based law. Evidential Pluralism is a theory of causal enquiry which maintains that one needs to scrutinise mechanistic studies alongside the experimental and observational studies that are the (...) focus of present-day evidence-based medicine and evidence-based policy. The paper develops a new approach to evidence-based law, called EBL+, based on the principles of Evidential Pluralism. Three examples show how the proposed methods work: banning hand-held mobile phone use while driving, sugar tax, and face-mask mandates for controlling Covid-19. (shrink)

We revisit Naturalized Epistemology and the Law of Evidence, published twenty years ago. The evolution of the relative plausibility theory of juridical proof is offered as evidence of the advantage of a naturalized approach to the study of the field and law evidence. Various alternative explanations of aspects of juridical proof from other disciplines are examined and their shortcomings described. These competing explanations are similar in their reductive, a priori approaches that are at odds with an empirically (...) oriented naturalized approach. The shortcomings of the various a priori approaches are driven by their common methodological commitments to employing weird hypotheticals to engage in intuition mining about the American legal systems that in turn ignore important aspects of the actual legal systems and consistently make impossible epistemological demands. As a result, both their descriptions of and prescriptions for American legal systems are implausible, unlike the relative plausibility theory. (shrink)

Attempts at quantification turn up in many areas within the modern courtroom, but nowhere more than in the realm of toxic tort law. Evidence, in these cases, is routinely presented in statistical form. The vagueness inherent in phrases such as 'balance of probabilities' and 'more likely than not' is reinterpreted to correspond to precise mathematical values. Standing alone these developments would not be a cause for great concern. But in practice courts and commentators have routinely mixed up incompatible quantities, (...) leading to grave injustice. I argue that these confusions result from an unjustified assumption of universal causal determinism. (shrink)
