Draws on a broad range of scientific evidence to theorize an evolutionary basis for religion, considering how religion may have served as an essential component of early society survival and that the brain may be inherently inclined toward religious behavior.

Many who think that naked statistical evidence alone is inadequate for a trial verdict think that use of probability is the problem, and something other than probability – knowledge, full belief, causal relations – is the solution. I argue that the issue of whether naked statistical evidence is weak can be formulated within the probabilistic idiom, as the question whether likelihoods or only posterior probabilities should be taken into account in our judgment of a case. This question also identifies a (...) major difference between the Process Reliabilist and Probabilistic Tracking views of knowledge and other concepts. Though both are externalist, and probabilistic, epistemic theories, Tracking does and Process Reliabilism does not put conditions on likelihoods. So Tracking implies that a naked statistic is not adequate evidence about an individual, and does not yield knowledge, whereas the Reliabilist thinks it gives justified belief and knowledge. Not only does the Tracking view imply that naked statistical evidence is insufficient for a verdict, but it gives us resources to explain why, in terms of risk and the special conditions of a trial.

From 1945 on for two decades, Father William Wade was Chairman of the Department of Philosophy at St. Louis University. This volume, a recovery of his own 1935 Ph.D dissertation, was originally written under the direction of Vernon J. Bourke, later himself a renowned interpreter of both St. Augustine and St. Thomas Aquinas. In his dissertation, Wade displays deep understanding of relationships between Greek and medieval thought as well as of the different influences of Plato and Aristotle by (...) way of Augustine and Thomas.

Sherrilyn Roush defends a new theory of knowledge and evidence, based on the idea of "tracking" the truth, as the best approach to a wide range of questions about knowledge-related phenomena. The theory explains, for example, why scepticism is frustrating, why knowledge is power, and why better evidence makes you more likely to have knowledge. Tracking Truth provides a unification of the concepts of knowledge and evidence, and argues against traditional epistemological realist and anti-realist positions about scientific theories and (...) for a piecemeal approach based on a criterion of evidence, a position Roush calls "real anti-realism." Epistemologists and philosophers of science will recognize this as a significant original contribution. (shrink)

Pezdek and Lam [Pezdek, K. & Lam, S. . What research paradigms have cognitive psychologists used to study “False memory,” and what are the implications of these choices? Consciousness and Cognition] claim that the majority of research into false memories has been misguided. Specifically, they charge that false memory scientists have been misusing the term “false memory,” relying on the wrong methodologies to study false memories, and misapplying false memory research to real world situations. We review each of these claims (...) and highlight the problems with them. We conclude that several types of false memory research have advanced our knowledge of autobiographical and recovered memories, and that future research will continue to make significant contributions to how we understand memory and memory errors.

People frequently report that, at times, their thought has a vocal character. Thinking commonly appears to be accompanied or constituted by silently ‘talking’ to oneself in inner speech. In this paper, we explore the specifically epistemic role of inner speech in conscious reasoning. A plausible position—but one I argue is ultimately wrong—is that inner speech plays asolelyfacilitative role that is exhausted by (i) serving as the vehicle of representation for conscious reasoning, and/or (ii) allowing one to focus on certain types (...) of objects or relations, e.g., causal relations, abstracta, counterfactuals, etc., or to consciously entertain structured propositional contents that it would be hard (or impossible) to focus on or entertain with representations in other (e.g., imagistic) formats. According to this position, inner speech doesn't figure as a justificatory element in our reasoning or as the partial epistemic basis of our conclusions—it merely facilitates reasoning through (i) and/or (ii). In contrast to the view that inner speech is amerefacilitator, I establish that (outside of potentially playing roles (i) and/or (ii)) the language we use itself serves as a crucial source of information in reasoning. In other words, we reason from propositions about the language we use in inner speech as opposed to exclusively reasoning from the semantic contents of the speech. My conclusion follows from how we use language as a cognitive tool to keep track of information, e.g., the contents of premises, lemmas, previous reasoning results, etc., in reasoning. (shrink)

The US populace appears to be increasingly polarized on partisan lines. Political fissures bifurcate the country even on empirical matters like vaccine safety and anthropogenic climate change. There now exists an ever-expanding interdisciplinary research program in which theorists attempt to explain increases in political polarization and myriad other phenomena collected under the “post-truth” heading by appeal to social-epistemic structures, like echo chambers and epistemic bubbles, that affect the flow and uptake of information in various communities. In this paper, I critically (...) analyze C. Thi Nguyen’s important and popular analysis of echo chambers and epistemic bubbles. As I demonstrate, the explanatory mechanisms on which Nguyen focuses are, arguably, overly cognitive and obscure significant effects of social-epistemic structures on our affective lives. The broader lesson to draw from my discussion is the following: commonly used expressions intended to refer to social-epistemic problems, like “political polarization”, possess no univocal definition across theorists, and various ways of making the terms precise are differentially successful in characterizing verifiable phenomena. Theorizing about social-epistemic structures should be responsive to relevant empirical work on various phenomena that we have good reason to believe constitute real and substantive problems that result from the flow and uptake of information.

People frequently report that their thought has, at times, a vocal character. Thinking commonly appears to be accompanied or constituted by silently ‘talking’ to oneself in inner speech. In this paper, I argue that inner speech ‘utterances’ can constitute occurrent propositional attitudes, e.g., occurrent judgments, suppositions, etc., and, thereby, we can consciously reason through tokening a series of inner speech utterances in working memory. As I demonstrate, the functional role a mental state plays in working memory is determined in a (...) flexible and context sensitive manner by metacognitive monitoring and control procedures. An inner speech utterance functions as an occurrent judgment (and, thus, as a premise, lemma, or conclusion in a line of conscious reasoning) when it is experienced with a level of certainty that exceeds one’s threshold of confidence for acceptance. In virtue of an agent experiencing an inner speech utterance with a sufficient level of certainty, the utterance plays the functional role of an occurrent judgment through, e.g., terminating inquiry and causing overt actions (like overtly asserting the words rehearsed in inner speech).

Before we can resolve or avoid an ethical dilemma, we need to understand what makes something ethical. Practical and Professional Ethics : Key Concepts introduces us to a series of real cases where the stakes can be high, the situations complex, and the ethical issues often difficult to see. Drawing on examples from medicine, law and science, it offers a practical approach to thinking critically about the ethical problems that occur in our professions, teaching us how to: focus on the (...) ethical aspects of any situation distinguish between different kinds of ethical problems tailor our response to the kind of problem we face construct arguments we can plausibly attribute to those involved identify the role of power, discretion and moral blindness By guiding us through the concepts, issues and skills at play when we face an ethical problem, we learn how to find a solution. Ideal for students or professionals, this book provides the grounding required to become a more complex moral thinker, a quality that can be applied in a number of fields and jobs. (shrink)

In light of recent social psychological literature, I expand Miranda Fricker’s important notion of testimonial injustice. A fair portion of Fricker’s account rests on an older paradigm of stereotype and prejudice. Given recent empirical work, I argue for what I dub prescriptive credibility deficits in which a backlash effect leads to the assignment of a diminished level of credibility to persons who act in counter-stereotypic manners, thereby flouting prescriptive stereotypes. The notion of a prescriptive credibility deficit is not merely an (...) interesting conceptual addendum that can be appended to Fricker’s theory without need for further emendation. I develop the wider implications of prescriptive credibility deficits and argue that they pose a challenge to Fricker’s conception of the function of credibility assignments in conversational exchange and how a virtuous listener should respond to the potential threat of a prejudicial stereotype affecting her credibility assignments.

Evidentialism as an account of epistemic justification is the position that a doxastic attitude, D, towards a proposition, p, is justified for an intentional agent, S, at a time, t, iff having D towards p fits S’s evidence at t, where the fittingness of an attitude on one’s evidence is typically analyzed in terms of evidential support for the propositional contents of the attitude. Evidentialism is a popular and well-defended account of justification. In this paper, I raise a problem for (...) evidentialism on the grounds that there can be epistemic circumstances in which a proposition is manifestly and nonmisleadingly supported by an agent’s total evidence, and yet believing the proposition is not justified for the agent. As I argue, in order for an agent to have justification to believe a proposition, it needs to be the case that the belief as possessed by the agent could exhibit certain epistemic good making features, e.g., the propositional content of the belief as possessed by the agent would be supported by the agent’s evidence. As I demonstrate, the fact that a proposition, p, is supported by an agent’s total evidence at a time, t, doesn’t guarantee that a belief in p as possessed by the agent at t could exhibit any epistemic good making features, including having propositional contents (i.e., p) that would be supported by the agent’s evidence. Thus, the fact that a proposition is supported by an agent’s evidence doesn’t guarantee that the agent has justification to believe the proposition. (shrink)

Our conscious thought, at least at times, seems suffused with language. We may experience thinking as if we were “talking in our head”, thus using inner speech to verbalize, e.g., our premises, lemmas, and conclusions. I take inner speech to be part of a larger phenomenon I call inner semiotics, where inner semiotics involves the subjective experience of expressions in a semiotic (or symbol) system absent the overt articulation of the expressions. In this paper, I argue that inner semiotics allows (...) us to bootstrap our way into entertaining thoughts about exact numbers and quantities that we couldn't prior to our competence with a numeric code. I establish that our arithmetic thoughts literally occur as (internal ‘articulations’ of) expressions in a numeric code. However, a problem arises for my view: just as we can slip in overt speech, producing an utterance that deviates from what we mean to say, there is very good evidence that we can slip in inner speech as well. If our arithmetic thought occurs in a numeric code, it's far from clear how we determine when a covert utterance constitutes a slip. In closing, I provide an account of what makes an inner speech utterance a slip. (shrink)

How confident does the history of science allow us to be about our current well-tested scientific theories, and why? The scientific realist thinks we are well within our rights to believe our best-tested theories, or some aspects of them, are approximately true.2 Ambitious arguments have been made to this effect, such as that over historical time our scientific theories are converging to the truth, that the retention of concepts and claims is evidence for this, and that there can be no (...) other serious explanation of the success of science than that its theories are approximately true. There is appeal in each of these ideas, but making such strong claims has tended to be hazardous, leaving us open to charges that many typical episodes in the history of science just do not fit the model. (See, e.g., Laudan 1981.) Arguing for a realist attitude via general claims – properties ascribed to sets of theories, trends we see in progressions of theories, and claimed links between general properties like success and truth that apply or fail to apply to any theory regardless of its content – is like arguing for or via a theory of science, which brings with it the obligation to defend that theory. I think a realist attitude toward particular scientific theories for which we have evidence can be maintained rationally without such a theory, even in the face of the pessimistic induction over the history of science. The starting point at which questions arise as to what we have a right to believe about our theories is one where we have theories and evidence for them, and we are involved in the activity of apportioning our belief in each particular theory or hypothesis in accord with the strength of the particular evidence.3 The devil’s advocate sees our innocence and tries his best to sow seeds of doubt. If our starting point is as I say, though, the innocent believer in particular theories does not have to play offense and propose sweeping views about science in general, but only to respond to the skeptic’s challenges; the burden of initial argument is on the skeptic..

Evidentialism as an account of theoretical rationality is a popular and well-defended position. However, recently, it's been argued that misleading higher-order evidence (HOE) – that is, evidence about one's evidence or about one's cognitive functioning – poses a problem for evidentialism. Roughly, the problem is that, in certain cases of misleading HOE, it appears evidentialism entails that it is rational to adopt a belief in an akratic conjunction – a proposition of the form “p, but my evidence doesn't support p” (...) – despite it being the case that believing an akratic conjunction appears to be clearly irrational. In this paper, I diffuse the problem for evidentialism using the distinction between propositional and doxastic rationality. I argue that, although it can be propositionally rational to believe an akratic conjunction (according to evidentialism), one cannot inferentially base an akratic belief in one's evidence, and, thus, one cannot doxastically rationally possess an akratic belief. In addition, I address the worry that my solution to the puzzle commits evidentialists to the possibility of epistemic circumstances in which a proposition, p, is propositionally rational to believe (namely, an akratic conjunction), yet one cannot, in principle, (doxastically) rationally believe p. As I demonstrate, cases of misleading HOE are not the only types of cases that force evidentialists to accept that propositional rationality does not entail the possibility of doxastic rationality. There are no new problems raised by misleading HOE that weren't already present in cases involving purely first-order evidence. (shrink)

More than 10,000 people have died in the Japanese tsunami, and the survivors are cold and hungry. But the media concentrate on nuclear radiation from which no one has died—and is unlikely to. Nuclear radiation at very high levels is dangerous, but the scale of concern that it evokes is misplaced. Nuclear technology cures countless cancer patients everyday—and a radiation dose given for radiotherapy in hospital is no different in principle to a similar dose received in the environment. What of (...) Three Mile Island? There were no known deaths there. And Chernobyl? The most recent UN report confirms the known death toll—28 fatalities among emergency workers plus 15 fatal cases of child thyroid cancer—which would have been avoided if iodine tablets had been taken. And in each case, the numbers are minute compared with the 3,800 people at Bhopal in 1984 who died as a result of a leak of chemicals from the Union Carbide pesticide plant. (shrink)

This paper defends the naïve thesis that the method of experiment has per se an epistemic superiority over the method of computer simulation, a view that has been rejected by some philosophers writing about simulation, and whose grounds have been hard to pin down by its defenders. I further argue that this superiority does not come from the experiment’s object being materially similar to the target in the world that the investigator is trying to learn about, as both sides of (...) dispute over the epistemic superiority thesis have assumed. The superiority depends on features of the question and on a property of natural kinds that has been mistaken for material similarity. Seeing this requires holding other things equal in the comparison of the two methods, thereby exposing that, under the conditions that will be specified, the simulation is necessarily epistemically one step behind the corresponding experiment. Practical constraints like feasibility and morality mean that scientists do not often face an other-things- equal comparison when they choose between experiment and simulation. Nevertheless, I argue, awareness of this superiority and of the general distinction between experiment and simulation is important for maintaining motivation to seek answers to new questions.

David Kaplan’s analysis of the factors that determine what words someone has used in a given utterance requires that a speaker can only use a word through producing an utterance performed with a particular, related intention directed at speaking that word. This account, or any that requires a speaker to have an intention to utter a specific word, proves inconsistent with models of speech planning in psycholinguistics as informed by data on slips-of-the-tongue. Kaplan explicitly aims to formulate a theory of (...) words that elides the details of the processes responsible for speech planning and production. Though it may superficially seem that the picture of speech planning and production offered by psycholinguistics can add no insight into our analysis—on closer inspection—we find a rich body of empirical data that should be integrated into any viable account of what words someone has used in a given utterance.

When we get evidence that tells us our belief-forming mechanisms may not be reliable this presents a thorny set of questions about whether and how to revise our original belief. This article analyzes aspects of the problem and a variety of approaches to its solution.

I develop a general framework with a rationality constraint that shows how coherently to represent and deal with second-order information about one's own judgmental reliability. It is a rejection of and generalization away from the typical Bayesian requirements of unconditional judgmental self-respect and perfect knowledge of one's own beliefs, and is defended by appeal to the Principal Principle. This yields consequences about maintaining unity of the self, about symmetries and asymmetries between the first- and third-person, and a principled way of (...) knowing when to stop second-guessing oneself. Peer disagreement is treated as a special case where one doubts oneself because of news that an intellectual equal disagrees. This framework, and variants of it, imply that the typically stated belief that an equally reliably peer disagrees is incoherent, and thus that pure rationality constraints without further substantive information cannot give an answer as to what to do. The framework also shows that treating both ourselves and others as thermometers in the disagreement situation does not imply the Equal Weight view. (shrink)

The results of the analysis determined that the NSCOA is predominantly a one-dimensional (exterior), two quadrant (behaviors and systems) policy.

Finally, recommendations are made to incorporate the principles of the Integral model into the workings (...) of the NSCOA. (shrink)

Previous accounting ethics research berates auditors for ethical lapses that contribute to the failure of Andersen (e.g., Duska, R.: 2005, Journal of Business Ethics 57, 17–29; Staubus, G.: 2005, Journal of Business Ethics 57, 5–15; however, some of the blame must also fall on regulatory and professional bodies that exist to mitigate auditors’ ethical lapses. In this paper, we consider the ethical and economic context that existed and facilitated Andersen’s failure. Our analysis is grounded in Akerlof’s (1970, Quarterly Journal of (...) Economics August, 488–500) Theory of the Market for Lemons and we characterize the market for audit reports as a market for lemons. Consistent with Akerlof’s model, we consider the appropriateness of the countervailing mechanisms that existed at the time of Andersen’s demise that appeared to have effectively failed in counteracting Andersen’s ethical shortcomings. Finally, we assess the appropriateness of the remedies proposed by the Sarbanes–Oxley Act of 2002 (SOA) to ensure that similar ethical lapses will not occur in the future. Our analysis indicates that the SOA regulatory reforms should counteract some of the necessary conditions of the Lemons Model, and thereby mitigate the likelihood of audit failures. However, we contend that the effectiveness of the SOA critically depends upon the focus and attention of the␣Public Companies Accounting Oversight Board (PCAOB) towards assessing the ethical climates of public accounting firms. Assessments by the PCAOB of public accounting firm’s ethical climate are needed to sufficiently ensure that public accounting firms effectively promote and maintain audit quality in situations where unconscious bias or economic incentives may erode the public accounting firm’s independence.

Self-knowledge has always played a role in healthcare since a person needs to be able to accurately assess her body or behaviour in order to determine whether to seek medical help. But more recently it has come to play a larger role, as healthcare has moved from a more paternalistic model to one where patients are expected to take charge of their health; as we realise that early detection, and hence self-examination, can play a crucial role in outcomes; as medical (...) science improves and makes more terminal illnesses into chronic conditions requiring self-management; as genetic testing makes it possible to have more information about our futures; and with the advent of personal electronic devices that make it easy for a person to gather accurate real-time information about her body. It can be hard to get good information about oneself, and even harder to know what to do it. Sometimes self-knowledge is needed for a good outcome, but sometimes it is useless, or worse. For instance, breast self-examination can lead to over-treatment, learning that one has a predisposing gene can create a detrimental illusion of knowing more about the future than one does, and data about one’s vital signs can be meaningless if taken out of a context of interpretation. This collection explores how these and other issues play out in a variety of medical specialities. (shrink)

There is a widespread view that in order to be rational we must mostly know what we believe. In the probabilistic tradition this is defended by arguments that a person who failed to have this knowledge would be vulnerable to sure loss, or probabilistically incoherent. I argue that even gross failure to know one's own beliefs need not expose one to sure loss, and does not if we follow a generalization of the standard bridge principle between first-order and second-order beliefs. (...) This makes it possible for a subject to use probabilistic decision theory to manage in a rational way cases of potential failure of this self-knowledge, as we find in implicit bias. Through such cases I argue that it is possible for uncertainty about what our beliefs are to be not only rationally permissible but advantageous. (shrink)

This paper argues that if knowledge is defined in terms of probabilistic tracking then the benefits of epistemic closure follow without the addition of a closure clause. (This updates my definition of knowledge in Tracking Truth 2005.) An important condition on this result is found in "Closure Failure and Scientific Inquiry" (2017).

Recently, a cottage industry has formed with the goal of analyzing reasoning. The relevant notion of reasoning in which philosophers are expressly interested is fixed through an epistemic functional description: reasoning—whatever it is—is our personal-level, rationally evaluable means of meeting our rational requirements through managing and updating our attitudes. Roughly, the dominant view in the extant literature as developed by Paul Boghossian, John Broome, and others is that reasoning is a rule-governed operation over propositional attitudes that results in a change (...) in attitude. In this paper, I argue that our personal-level operations over mental models and visuospatial imagery, which are representations in a non-propositional/analogue format, can be rationally evaluable processes of managing our attitudes and, thus, should be considered reasoning in the relevant sense. Furthermore, I show that if reasoning can occur through operations over mental models and imagery, then the dominant rule-following account mischaracterizes the cognitive operations and representational states assumed to be constitutive of reasoning and what grounds the rational status of a line of reasoning.

This is a new release of the original 1949 edition.

In updating our beliefs on the basis of our background attitudes and evidence we frequently employ objects in our environment to represent pertinent information. For example, we may write our premises and lemmas on a whiteboard to aid in a proof or move the beads of an abacus to assist in a calculation. In both cases, we generate extramental (that is, occurring outside of the mind) representational states, and, at least in the case of the abacus, we operate over these (...) states in light of their contents (e.g., the integers represented by the beads) to generate new representations. In this paper, I argue that our belief updating processes and the grounds of their rational evaluation are partly constituted by extramental representations and operations. In other words, we don’t merely update our attitudes through an internal process of reasoning on the basis of available evidence. If we are to accurately understand and rationally evaluate our belief updating processes and resultant attitudes, we need to examine how we representationally appropriate our extramental environment in the updating process.

ABSTRACT Ethical and political attitudes are not randomly distributed in a population. Attitudes of family members, for example, tend to be more similar than those of a random sample of the same size. In the fields of social psychology and political science, the historically standard explanation for these attitude distribution patterns was that social and political attitudes are a function of environmental factors like parental socialization and prevailing social norms. This received view is, however, complicated by more recent work in (...) behavioral genetics, which consistently and repeatedly demonstrates that certain ethical and political attitudes dealing with issues like censorship, abortion, capital punishment, and immigration policy have a significant heritability coefficient, to wit, a substantial percentage of attitude variance in a population can be attributed to genetic variance, independent of environmental factors. In this paper, I argue that the genetic influence on our ethical and political attitudes is mediated by what we can agree to be irrelevant and distorting factors that can lead moral reasoning astray. Further, I argue that we should significantly lower our credences in ethical and political attitudes that fall within the domains of belief that involve significant genetic influence. (shrink)

It is received wisdom that the skeptic has a devastating line of argument in the following. You probably think, he says, that you know that you have hands. But if you knew that you had hands, then you would also know that you were not a brain in a vat, a brain suspended in fluid with electrodes feeding you perfectly coordinated impressions that are generated by a supercomputer, of a world that looks and moves just like this one. You would (...) know you weren’t in this state if you knew you had hands, since having hands implies you are no brain in a vat. You obviously don’t know you’re not a brain in a vat, though—you have no evidence that would distinguish that state from the normal one you think you’re in. Therefore, by modus tollens, you don’t know you have hands. At least, the skeptic has a devastating argument, it is thought, if we grant him closure of knowledge under known implication, which many of us are inclined to do: roughly, if you know p, and you know that p implies q, then you know q.

Recently, a cottage industry has formed with the expressed intent of analyzing the nature of personal-level reasoning and inference. The dominant position in the extant philosophical literature is that reasoning consists in rule-governed operations over propositional attitudes. In addition, it is widely assumed that our attitude updating procedures are purely cognitive. Any non-cognitive activity performed in service of updating our attitudes is external to the updating process—at least in terms of rational evaluation. In this paper, I argue that whether one (...) has rationally updated one’s attitudes and whether the resultant attitudes are rational can (at least partially) depend on one’s interactions with one’s environment and body to scaffold one’s ability to arrive at attitudes that are rationally appropriate given one’s evidence.
