For many epistemologists, and for many philosophers more broadly, it is axiomatic that rationality requires you to take the doxastic attitudes that your evidence supports. Yet there is also another current in our talk about rationality. On this usage, rationality is a matter of the right kind of coherence between one's mental attitudes. Surprisingly little work in epistemology is explicitly devoted to answering the question of how these two currents of talk are related. But many implicitly assume that (...) class='Hi'>evidence -responsiveness guarantees coherence, so that the rational impermissibility of incoherence will just fall out of the putative requirement to take the attitudes that one's evidence supports, and so that coherence requirements do not need to be theorized in their own right, apart from evidential reasons. In this paper, I argue that this is a mistake, since coherence and evidence -responsiveness can in fact come into conflict. More specifically, I argue that in cases of misleading higher-order evidence, there can be a conflict between believing what one's evidence supports and satisfying a requirement that I call “inter-level coherence ”. This illustrates why coherence requirements and evidential reasons must be separated and theorized separately. (shrink)

In this paper, I propose and defend a pair of necessary conditions on evidence-based knowledge which bear resemblance to the troubled sensitivity principles defended in the philosophical literature. We can think of the traditional principles as simple but inaccurate approximations of the new proposals. Insofar as the old principles are intuitive and used in scientific and philosophical contexts, but are plausibly false, there’s a real need to develop precise and correct formulations. These new renditions turned out to be more (...) cautious, so they won’t be able to do everything the old principled promised they could. For example, they respect closure for knowledge. But these sober formulations, or something like them, might be the best that we can do with respect to sensitivity. And there’s value in understanding the limits to these types of principles.

This book is concerned with the role of intuitions in the justification of philosophical theory. The author begins by demonstrating how contemporary philosophers, whether engaged in case-driven analysis or seeking reflective equilibrium, rely on intuitions as evidence for their theories. The author then provides an account of the nature of philosophical intuitions and distinguishes them from other psychological states. Finally, the author defends the use of intuitions as evidence by demonstrating that arguments for skepticism about their evidential value (...) are either self-defeating or guilty of arbitrary and unjustified partiality towards non-intuitive modes of knowledge.

Sensitivity-type principles are prominent in epistemology. They have the promise to explain our intuitive and considered reactions to a wide range of important cases in everyday life, science and philosophy. Despite this promise, philosophers have raised a number of very serious objections to the principles. Accordingly, I propose a different type of sensitivity account which, I believe, gets around these serious objections. An important feature of the new approach is that the principle I propose need not be true. Rather, it (...) should be understood as a cognitive heuristic that tells us when something is not known—a type of doubt. A second feature is that the principle does not care about what one’s belief would be like in counter-factual situations. Instead, it cares about what the bases or causes for the belief would be like in those situations. (shrink)

Many people have recently argued that we need to distinguish between experiences and seemings and that this has consequences for views about how perception provides evidence. In this article I spell out my take on these issues by doing three things. First, I distinguish between mere sensations like seeing pitch black all around you and perceptual experiences like seeing a red apple. Both have sensory phenomenology in presenting us with sensory qualities like colors, being analog in Dretske's sense, and (...) being fine-grained. However, only the latter have furthermore a perceptual phenomenology characterized by objectification and related dualities of perspectivality/completion and variation/constancy. Second, I elaborate on the reasons for thinking that both mere sensations and perceptual experiences need to be distinguished from accompanying seemings that passively assign things into conceptual categories and thereby tell you something about them. For example, when you look at a red apple and have the relevant recognitional abilities it will also normally seem to you that this is an apple. Finally, I argue that the best version of the popular dogmatist view about evidence is one which claims that it's neither experiences nor seemings by themselves, but rather the right sorts of composites of experiences and seemings that provide evidence.

Gott ( 1993 ) has used the ‘Copernican principle’ to derive a probability distribution for the total longevity of any phenomenon, based solely on the phenomenon’s past longevity. Leslie ( 1996 ) and others have used an apparently similar probabilistic argument, the ‘Doomsday Argument’, to claim that conventional predictions of longevity must be adjusted, based on Bayes’s Theorem, in favor of shorter longevities. Here I show that Gott’s arguments are flawed and contradictory, but that one of his conclusions is plausible (...) and mathematically equivalent to Laplace’s famous—and notorious—‘rule of succession’. On the other hand, the Doomsday Argument, though it appears consistent with some common‐sense grains of truth, is fallacious; the argument’s key error is to conflate future longevity and total longevity. Applying the work of Hill ( 1968 ) and Coolen ( 1998 , 2006 ) in the field of nonparametric predictive inference, I propose an alternative argument for quantifying how past longevity of a phenomenon does provide evidence for future longevity. In so doing, I identify an objective standard by which to choose among counting time intervals, counting population, or counting any other measure of past longevity in predicting future longevity. *Received May 2007; revised October 2008. †To contact the author, please e‐mail: [email protected].

Taxometric analyses were applied to the construct of psychopathy (as measured by the Psychopathy Checklist) and to several variables reflecting antisocial childhood, adult criminality, and criminal recidivism. Subjects were 653 serious offenders assessed or treated in a maximum-security institution. Results supported the existence of a taxon underlying psychopathy. Childhood problem behaviors provided convergent evidence for the existence of the taxon. Adult criminal history variables were continuously distributed and were insufficient in themselves to detect the taxon.

Original and penetrating, this book investigates of the notion of inference from signs, which played a central role in ancient philosophical and scientific method. It examines an important chapter in ancient epistemology: the debates about the nature of evidence and of the inferences based on it--or signs and sign-inferences as they were called in antiquity. As the first comprehensive treatment of this topic, it fills an important gap in the histories of science and philosophy.

Causal claims in biomedical contexts are ubiquitous albeit they are not always made explicit. This paper addresses the question of what causal claims mean in the context of disease. It is argued that in medical contexts causality ought to be interpreted according to the epistemic theory. The epistemic theory offers an alternative to traditional accounts that cash out causation either in terms of “difference-making” relations or in terms of mechanisms. According to the epistemic approach, causal claims tell us about which (...) inferences (e.g., diagnoses and prognoses) are appropriate, rather than about the presence of some physical causal relation analogous to distance or gravitational attraction. It is shown that the epistemic theory has important consequences for medical practice, in particular with regard to evidence-based causal assessment. (shrink)

This text draws on the evidence of Paul and the Gospels to present the case for accepting the historicity of the bodily resurrection of Jesus.

Amalgamating evidence of different kinds for the same hypothesis into an overall confirmation is analogous, I argue, to amalgamating individuals’ preferences into a group preference. The latter faces well-known impossibility theorems, most famously “Arrow’s Theorem”. Once the analogy between amalgamating evidence and amalgamating preferences is tight, it is obvious that amalgamating evidence might face a theorem similar to Arrow’s. I prove that this is so, and end by discussing the plausibility of the axioms required for the theorem.

Given the risks of misinformation, addressees need to calibrate their trust towards communicators effectively. One way to do this is to evaluate the evidence speakers rely on (their evidential warrant) or claim to have (their evidential claims) when providing testimony. We review key findings in experimental psychology and experimental pragmatics to uncover the mechanisms underlying this form of trust calibration. This will ultimately shed light on the psychological foundations of principles that guide the evaluation of testimony in legal contexts, (...) such as the law against hearsay. (shrink)

Statements are always under the threat of the potential counter-question How do you know? To pre-empt this question, language users often indicate what kind of access they had to the communicated content: Their own perception, inference from other information, 'hearsay', etc. Such expressions, grammatical or lexical, have been studied in recent years under the cover term of evidentiality research. The present volume contributes 11 new studies to this flourishing field, all exploring evidential phenomena in a range of languages (Dutch, Estonian, (...) Finnish, French, German, Khalkha Mongolian, Spanish, Tibetan, Yurakaré), using a variety of methodologies. Evidential meaning is discussed in relation to other semantic dimensions, such as epistemic modality, semantic roles, commitment, quotative meaning, and tense. The volume is of interest to scholars and students who are interested in up-to-date methods and frameworks for studying evidential meaning and the various ways it is expressed in the languages of the world.

The primacy in modern medical ethics of the principle of respect for autonomy has led to the widespread assumption that it is unethical to change someone’s beliefs, because doing so would constitute coercion or paternalism., In this Viewpoint we suggest that persuasion is not necessarily paternalistic and is an essential component of modern medical practice.

This monograph poses a series of key problems of evidential reasoning and argumentation. It then offers solutions achieved by applying recently developed computational models of argumentation made available in artificial intelligence. Each problem is posed in such a way that the solution is easily understood. The book progresses from confronting these problems and offering solutions to them, building a useful general method for evaluating arguments along the way. It provides a hands-on survey explaining to the reader how to use current (...) argumentation methods and concepts that are increasingly being implemented in more precise ways for the application of software tools in computational argumentation systems. It shows how the use of these tools and methods requires a new approach to the concepts of knowledge and explanation suitable for diverse settings, such as issues of public safety and health, debate, legal argumentation, forensic evidence, science education, and the use of expert opinion evidence in personal and public deliberations.

This is a study of the logic of the concept of evidence. Two distinct concepts of evidence will be explicated and analyzed: confirming evidence by means of which an hypothesis is established, and supporting evidence which does not establish the hypothesis, but merely renders it more tenable. The formal characteristics of each of these concepts of evidence will be examined in detail in Part II. In Part III these considerations are used as a basis for (...) a survey of rules of evidence in order to establish the systematic character of the evidential relationship from the standpoint of formal logic. Finally, the Conclusion appends a brief indication of the methodological bearing of the logical theory of evidence. (shrink)

_ Source: _Page Count 19 Epistemic akrasia refers to the possibility of forming an attitude that fails to conform to one’s best judgment. In this paper, I will be concerned with the question whether epistemic akrasia is rational and I will argue that it is not. Addressing this question, in turn, raises the question of the epistemic significance of higher-order evidence. After examining some of the views on this subject, I will present an argument to show why higher-order (...) class='Hi'>evidence is relevant to the epistemic status of the pertinent first-order beliefs. This helps to show why a standard argument for the rationality of epistemic akrasia does not work. Finally, I shall try to show how considerations involving Davidson’s theory of radical interpretation bear on the question of the rationality of epistemic akrasia. (shrink)

Literature on maternal exposures and the risk of epigenetic changes or diseases in the offspring is growing. Paternal contributions are often not considered. However, some animal and epidemiologic studies on various contaminants, nutrition, and lifestyle‐related conditions suggest a paternal influence on the offspring's future health. The phenotypic outcomes may have been attributed to DNA damage or mutations, but increasing evidence shows that the inheritance of environmentally induced functional changes of the genome, and related disorders, are (also) driven by epigenetic (...) components. In this essay we suggest the existence of epigenetic windows of susceptibility to environmental insults during sperm development. Changes in DNA methylation, histone modification, and non‐coding RNAs are viable mechanistic candidates for a non‐genetic transfer of paternal environmental information, from maturing germ cell to zygote. Inclusion of paternal factors in future research will ultimately improve the understanding of transgenerational epigenetic plasticity and health‐related effects in future generations. (shrink)

Modern science faces a series of problems that undermine confidence in its reliability. To solve these problems, we must reflect on what makes science work and what leads it astray. This book is about Science, its strengths and weaknesses. The papers that scientists write form a vast resource of evidence and theory that is doubling about every ten years, along with the number of scientists. The size of this resource makes it hard for it to be used effectively by (...) scientists, and along with this are growing concerns about its integrity and reliability. This book looks at the scientific method, as currently applied and as understood philosophically by scientists, the social structure of science, and the structure of scientific communication through journals. It includes case studies of controversies, and looks at how fields develop over time. (shrink)

To whatever extent the use of a behavioral, not an evidential, interpretation of decisions in the Lindley-Savage argument for Bayesian theory undermines its cogency as a criticism of typical standard practice, it also undermines the Neyman-Pearson theory as a support for typical standard practice. This leaves standard practice with far less theoretical support than Bayesian methods. It does nothing to resolve the anomalies and paradoxes of standard methods. (Similar statements apply to the common protestation that the models are not real (...) anyway.) The appropriate interpretation of tests as evidence, if possible at all, is difficult and counterintuitive. Any attempt to support tests as more than rules of thumb is doomed to failure. (shrink)

Nurses in Ghana believe that training, practise, practitioner and policy reforms are required for total nursing profession reform to be effective. Their views for role reformation in the nursing profession, which is currently needed, are not only academic but also clinically relevant in the pursuit of health equity and quality nursing care. We explored and described nurses’ views on their roles in the profession using data collected from 24 professional nurses in three regional hospitals in Ghana. Using an inductive descriptive (...) qualitative design, data were gathered and analysed using a qualitative content analysis to describe the views of the nurses. Four major themes, namely practise reforms, practitioner reforms, training reforms and policy reforms have emerged in relation to role reformation in the nursing profession. Three strategic areas, practitioner attitudes, new training modalities and policy realignment, must be reviewed and remodelled for better positioning of the nursing profession before its entire role reformation.

There are legitimate worries about gaps between scientific evidence of brain states and function (for example, as evidenced by fMRI data) and legal criteria for determining criminal culpability. In this paper I argue that behavioral evidence of capacity, motive and intent appears easier for judges and juries to use for purposes of determining criminal liability because such evidence triggers the application of commonsense psychological (CSP) concepts that guide and structure criminal responsibility. In contrast, scientific evidence of (...) neurological processes and function – such as evidence that the defendant has a large brain tumor – will not generally lead a judge or jury to directly infer anything that is relevant to the legal determination of criminal culpability . (Vincent 2008) In these cases, an expert witness will be required to indicate to the fact-finder what this evidence means with regard to mental capacity; and then another inference will have to be made from this possible lack of capacity to the legal criteria for guilt, cast in CSP terms.<br><br>To reliably link evidence of brain function and structure and assessment of criminal responsibility, we need to re-conceptualize the mental capacities necessary for responsibility, particularly those that are recognized as missing or compromised by the doctrines of “legal capacity” (Hart 1968) and “diminished capacity.” I argue that formulating these capacities as executive functions within the brain can provide this link. I further claim that it would be extremely useful to consider evidence of executive function as related to the diminished capacity doctrine at sentencing. This is because it is primarily at this stage in criminal proceedings where the use of the diminished capacity doctrine is most prevalent, as evidenced by the recent Supreme Court cases of Atkins v. Virginia (536 U.S. 304 (2002)) and Roper v. Simmons (543 U.S. 551 (2005)).<br>. (shrink)

Sometimes, a proposition is fictional in a story in virtue of the fact that other fictional truths are good evidence for it. Cases are presented in which this evidential rule, and not some rule that invokes counterfactuals or intentions, is what explains what is fictional. Applications are made to the question of interpretive pluralism and the problem of imaginative resistance. In the background is pluralism about fictionality: the evidential rule is one of a variety of rules that are needed (...) to account for what is fictional in a story. (shrink)

Governing nursing conduct: the rise of evidence‐based practice Drawing on the Foucauldian concept of ‘governmentality’ to analyse the evidence‐based movement in nursing, we argue that it is possible to identify the governance of nursing practice and hence nurses across two distinct axes; that of the political (governance through political and economic means) and the personal (governance of the self through the cultivation of the practices required by nurses to put evidence into practice). The evaluation of nursing work (...) through evidence‐based reviews provides detailed information that may enable governments to target and instruct nurses regarding their work in the interest of preserving the health of the population as a whole. Political governance of the nursing population becomes possible through centralised discursive mechanisms, such as evidence‐based reviews that present nursing practice as an intelligible field whose elements are connected in a more or less systematic manner. The identity of the evidence‐based nurse requires the modern nurse to develop new skills and attitudes. Evidence‐based nursing is an emerging technology of government that judges nursing research and knowledge and has the capacity to direct nursing practice at both the political and personal level.

It seems improbable that life would exist in a naturalistic universe. But if the universe were spatially infinite, then seemingly improbable events would be expected to happen; life would be expected to exist. It follows that the existence of life provides evidence that the universe is spatially infinite.

This paper critically analyzes Sherrilyn Roush’s (2005) definition of evidence and especially her powerful defence that in the ideal, a claim should be probable to be evidence for anything. We suggest that Roush treats not one sense of ‘evidence’ but three: relevance, leveraging and grounds for knowledge; and that different parts of her argument fare differently with respect to different senses. For relevance, we argue that probable evidence is sufficient but not necessary for Roush’s own two (...) criteria of evidence to be met. With respect to grounds for knowledge, we agree that high probability evidence is indeed ideal for the central reason Roush gives: When believing a hypothesis on the basis of e it is desirable that e be probable. But we maintain that her further argument that Bayesians need probable evidence to warrant the method they recommend for belief revision rests on a mistaken interpretation of Bayesian conditionalization. Moreover, we show that attempts to reconcile Roush’s arguments with Bayesianism fail. For leveraging, which we agree is a matter of great importance, the requirement that evidence be probable suffices for leveraging to the probability of the hypothesis if either one of Roush’s two criteria for evidence are met. Insisting on both then seems excessive. To finish, we show how evidence, as Roush defines it, can fail to track the hypothesis. This can remedied by adding a requirement that evidence be probable, suggesting another rationale for taking probable evidence as ideal – but only for a grounds-for-knowledge sense of evidence.

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.

To what extent does the design of statistical experiments, in particular sequential trials, affect their interpretation? Should postexperimental decisions depend on the observed data alone, or should they account for the used stopping rule? Bayesians and frequentists are apparently deadlocked in their controversy over these questions. To resolve the deadlock, I suggest a three‐part strategy that combines conceptual, methodological, and decision‐theoretic arguments. This approach maintains the pre‐experimental relevance of experimental design and stopping rules but vindicates their evidential, postexperimental irrelevance. †To (...) contact the author, please write to: Tilburg Center for Logic and Philosophy of Science, Tilburg University, P.O.

I offer a critical treatment of the contrastivist response to the problem of radical scepticism. In particular, I argue that if contrastivism is understood along externalist lines then it is unnecessary, while if it is understood along internalist lines then it is intellectually dissatisfying. Moreover, I claim that a closer examination of the conditions under which it is appropriate to claim knowledge reveals that we can accommodate many of the intuitions appealed to by contrastivists without having to opt for this (...) particular brand of epistemological revisionism.

Case studies of science concerning the interpretation of specific theories and the nature of theory change over time are often presented as evidence for or against forms of selective realism: versions of scientific realism that advocate belief in connection with certain components of theories as opposed to their content as a whole. I consider the question of how probative case studies can be in this sphere, focusing on two prominent examples of selectivity: explanationist realism, which identifies realist commitment with (...) components of theories that are putatively required to explain their empirical success; and entity realism, which identifies realist commitment with certain putatively causally efficacious entities. I argue that while case studies are essential to debates about these positions, they are not compelling in the way that their intended use suggests. Regarding explanationism, concerns about the “neutrality” of historical evidence are ultimately indefeasible. Regarding entity realism, arguments for and against naturally dissolve into disputes about the reference of theoretical terms which are insulated from the details of cases. I conclude by suggesting that the morals of this discussion extend to other forms of selective realism, namely structural realism and semirealism. (shrink)

Although scientists dating back to Darwin have noted the importance of the body in communicating emotion, current research on emotion communication tends to emphasize the face. In this article we review the evidence for bodily expressions of emotions—that is, the handful of emotions that are displayed and recognized from certain bodily behaviors. We also review the previously developed coding systems available for identifying emotions from bodily behaviors. Although no extant coding system provides an exhaustive list of bodily behaviors known (...) to communicate a panoply of emotions, our review provides the foundation for developing such a system.

In his paper "The Design Argument," Elliott Sober predicts that "human beings will eventually build organisms from nonliving materials."[1] In that case, we could obtain clear evidence that certain organisms resulted from intelligent design whereas earlier we might have thought they were due to a Darwinian process. I consider a similar possibility in chapter 6 of No Free Lunch.

The new evidence scholarship addresses three distinct approaches: legal probabilism, Bayesian decision theory and relative plausibility theory. Each has major insights to offer, but none seems satisfactory as it stands. This paper proposes that relative plausibility theory be modified in two substantial ways. The first is by defining its key concept of plausibility, hitherto treated as primitive, by generalising the standard axioms of probability. The second is by complementing the descriptive component of the theory with a normative decision theory (...) adapted to legal process. Because this version of decision theory is based on plausibilities rather than probabilities, it generates plausibilistic expectations as outputs. Because these outputs are comparable, they function as relative plausibilities. Hence the resulting framework is an extension of relative plausibility theory, but it retains deep ties to legal probabilism, through the proposed definition of plausibility, and to Bayesian decision theory, through the normative use of decision theory.
