Is truth objective or relative? What exists independently of our minds? The essays in this book debate these two questions, which are among the oldest of philosophical issues and have vexed almost every major philosopher, from Plato, to Kant, to Wittgenstein. Fifteen eminent contributors bring fresh perspectives, renewed energy, and original answers to debates of great interest both within philosophy and in the culture at large.

In this paper we discuss three different kinds of disagreement that have been, or could reasonably be, characterized as deep disagreements. Principle level disagreements are disagreements over the truth of epistemic principles. Sub-principle level deep disagreements are disagreements over how to assign content to schematic norms. Finally, framework-level disagreements are holistic disagreements over meaning not truth, that is over how to understand networks of epistemic concepts and the beliefs those concepts compose. Within the context of each of these kinds of (...) disagreement it is not possible for the parties to the dispute to rationally persuade one another through only offering epistemic reasons for their conflicting points of view. However, in spite of the inability to rationally persuade, we explore how it may nevertheless be possible to rationally navigate each of these varieties of deep disagreement. (shrink)

Can we give objective reasons for our most basic standards of reason-- our fundamental epistemic principles? I argue, against several forms of skepticism about reason, that we can, but that the reasons we can give for epistemic principles are ultimately practical, not epistemic.

ABSTRACTDemocracies, Dewey and others have argued, are ideally spaces of reasons – they allow for an exchange of reasons both practical and epistemic by those willing to engage in that discourse. That requires that citizens have convictions they believe in, but it also requires that they be willing to listen to each other. This paper examines how a particular psychological attitude, “epistemic arrogance,” can undermine the achievement of these goals. The paper presents an analysis of this attitude and then examines (...) four arguments for how its adoption – especially by the powerful – undermines the ideal of democracy as a space of reasons.

Imagine you had the functions of your smartphone miniaturized to a cellular level and accessible by your neural network. Reflection on this possibility suggests that we should not just concern ourselves with whether our knowledge is extending “out” to our devices; our devices are extending in, and with them, possibly the information that they bring. If so, then the question of whether knowledge is “extended” becomes wrapped up with the question of whether knowing is something we do, or something we (...) can share with, or outsource to, instruments. And that in turn raises the two questions of this paper: First, to what extent does such technology put pressure on the idea that we might have more than one conception of knowledge? And second, what is the value of states that fit these conceptions of knowledge? (shrink)

Why does reason matter, if in the end everything comes down to blind faith or gut instinct? Why not just go with what you believe even if it contradicts the evidence? Why bother with rational explanation when name-calling, manipulation, and force are so much more effective in our current cultural and political landscape? Michael Lynch's In Praise of Reason offers a spirited defense of reason and rationality in an era of widespread skepticism--when, for example, people reject scientific evidence about (...) such matters as evolution, climate change, and vaccines when it doesn't jibe with their beliefs and opinions. In recent years, skepticism about the practical value of reason has emerged even within the scientific academy. Many philosophers and psychologists claim that the reasons we give for our most deeply held views are often little more than rationalizations of our prior convictions. _In_ _Praise of Reason_ gives us a counterargument. Although skeptical questions about reason have a deep and interesting history, they can be answered. In particular, appeals to scientific principles of rationality are part of the essential common currency of any civil democratic society. The idea that everything is arbitrary--that reason has no more weight than blind faith--undermines a key principle of a civil society: that we owe our fellow citizens explanations for what we do. Reason matters--not just for the noble ideal of truth, but for the everyday world in which we live. (shrink)

Humility is a vital aspect of political discussion, social media and self-help, whilst recent empirical research has linked humility to improved well-being, open-mindedness and increased accuracy in assessing persuasive messages. It is also a topic central to research and discussion in philosophy, applied ethics and religious studies. The Routledge Handbook of Philosophy of Humility is the first collection to present a comprehensive overview the philosophy of humility, whilst also covering important interdisciplinary topics. Comprising forty-one chapters by an international team of (...) contributors, the Handbook is divided into seven parts: Theories of Humility The Ethics of Humility The Politics of Humility Humility in Religious Thought The Epistemology of Humility The Psychology of Humility Humility: Applications to the Social World. Essential reading for students and researchers in ethics, epistemology, political philosophy, and philosophy of mind and psychology, this Handbook will also be extremely useful for those in related disciplines such as psychology, religious studies and law.

One of the most influential analytic philosophers of the late twentieth century, William P. Alston is a leading light in epistemology, philosophy of religion, and the philosophy of language. In this volume, twelve leading philosophers critically discuss the central topics of his work in these areas, including perception, epistemic circularity, justification, the problem of religious diversity, and truth.

Bald-faced lies are on the uptick by political leaders in democracies worldwide. In the United States, for example, we are becoming numb not only to outrageous falsehoods, but to the bizarre self-assurance with which they are pronounced. We were told crowds were bigger than they were, that the sun shined when it didn’t, that Trump won in a landslide—and that was just in the first few days after his election. What has shocked so many is the fearlessness in the face (...) of the facts, the willingness to simply deny reality outright, and the apparent toleration—even joy—with which Trump’s followers greet the practice. Bald-faced lying by political leaders is an important phenomenon, but it is easy to misunderstand in ways that undermine our ability to combat its strange effectiveness. In this paper, I aim to first analyze political bald-faced lies and then examine the threat they pose to the norms of democratic discourse. My goal is not to answer the empirical question of how frequently denials of obvious facts occur in politics; it is the normative question of understanding what harms they cause — particularly when they are made by those — in political power. Nonetheless, I think it is important to resist the temptation to think that what we are talking about here are a few isolated and extreme examples. As Hannah Arendt noted, there are times in political life when truth, “if it happens to oppose a given group’s profit or pleasure, is greeted with greater hostility.” Arguably we are living in one of those times.

What is truth? Michael Lynch defends a bold new answer to this question. Traditional theories hold that all truths are true in the same way. More recent theories claim that the concept of truth is of no real importance. Lynch argues against both these extremes: truth is a functional property whose function can be performed in more than one way.

When payment is offered for controlled human infection model research, ethical concerns may be heightened due to unfamiliarity with this study design as well as perceptions—and misperceptions—regarding risk. Against this backdrop, we commend Grimwade et al 1 for their careful handling of the relevant issues, coupling empirical and conceptual approaches. We agree with foundational elements of the authors’ analysis, including the acceptability of payment for research risk.1 However, in our view, it is preferable to treat payment for risk as a (...) discretionary incentive to achieve adequate recruitment and retention, rather than compensation owed as a matter of fairness. Grimwade et al 1 note that although their ‘Payment for Risk Model’ was ‘created specifically in the context of CHIM research, it has the potential to inform payment in other areas of medical research.’ We agree and would go further: we do not need a special payment framework for CHIMs because there is nothing so novel about them compared with other types of research as to demand a distinct approach. Any successful payment framework must address the following ethical issues: preserving informed consent ; treating participants fairly ; encouraging adequate recruitment and retention; avoiding deception by participants; and preserving public trust.2 Some of these issues may have particular salience in the context of CHIMs, but this study design does not demand consideration of entirely distinct ethical factors when evaluating offers of payment.2 We also agree with Grimwade et al 1 about several other key points.2 Given the burdens involved and ….

The primary purpose of Institutional Review Boards (IRBs) is to protect the rights and welfare of human research participants. Evaluation and measurement of how IRBs satisfy this purpose and other important goals are open questions that demand empirical research. Research on IRBs, and the Human Research Protection Programs (HRPPs) of which they are often a part, is necessary to inform evidence-based practices, policies, and approaches to quality improvement in human research protections. However, to date, HRPP and IRB engagement in empirical (...) research about their own activities and performance has been limited. To promote engagement of HRPPs and IRBs in self-reflective research on HRPP and IRB quality and effectiveness, barriers to their participation need to be addressed. These include: extensive workloads, limited information technology systems, and few universally accepted or consistently measured metrics for HRPP/irb quality and effectiveness. Additionally, institutional leaders may have concerns about confidentiality. Professional norms around the value of participating in this type of research are lacking. Lastly, obtaining external funding for research on IRBs and HRPPs is challenging. As a group of HRPP professionals and researchers actively involved in a research consortium focused on IRB quality and effectiveness, we identify potential levers for supporting and encouraging HRPP and IRB engagement in research on quality and effectiveness. We maintain that this research should be informed by the core principles of patient- and community-engaged research, in which members and key stakeholders of the community to be studied are included as key informants and members of the research team. This ensures that relevant questions are asked and that data are interpreted to produce meaningful recommendations. As such, we offer several ways to increase the participation of HRPP professionals in research as participants, as data sharers, and as investigators. (shrink)

Human microbiome research makes causal connections between entire microbial communities and a wide array of traits that range from physiological diseases to psychological states. To evaluate these causal claims, we first examine a well-known single-microbe causal explanation: of Helicobacter pylori causing ulcers. This apparently straightforward causal explanation is not so simple, however. It does not achieve a key explanatory standard in microbiology, of Koch’s postulates, which rely on manipulations of single-microorganism cultures to infer causal relationships to disease. When Koch’s postulates (...) are framed by an interventionist causal framework, it is clearer what the H. pylori explanation achieves and where its explanatory strengths lie. After assessing this ‘simple’, single-microbe case, we apply the interventionist framework to two key areas of microbiome research, in which obesity and mental health states are purportedly explained by microbiomes. Despite the experimental data available, interventionist criteria for explanation show that many of the causal claims generated by microbiome research are weak or misleading. We focus on the stability, specificity and proportionality of proposed microbiome causal explanations, and evaluate how effectively these dimensions of causal explanation are achieved in some promising avenues of research. We suggest some conceptual and explanatory strategies to improve how causal claims about microbiomes are made. (shrink)

Background Meaningfully evaluating the quality of institutional review boards (IRBs) and human research protection programs (HRPPs) is a long-recognized challenge. To be accredited by the Association for the Accreditation of Human Research Protection Programs (AAHRPP), organizations must demonstrate that they measure and improve HRPP “quality, effectiveness, and efficiency” (QEE). We sought to learn how AAHRPP-accredited organizations interpret and satisfy this standard, in order to assess strengths, weaknesses, and gaps in current approaches and to inform recommendations for improvement.Methods We conducted 3 (...) small-group interviews with a total of 19 participant representatives of accredited organizations at the 2019 AAHRPP annual meeting. Participants were eligible if they had familiarity with their organization’s approach to satisfying the relevant QEE standard.Results Participants reported lacking clear definitions for HRPP quality or effectiveness but described various approaches to assessing QEE, typically focused on turnaround time, compliance, and researcher satisfaction. Evaluation of IRB members was described as relatively superficial and information regarding research subject experience was not reported as central to QEE assessment, although participants described several efforts to improve consideration of patient, subject, and community perspectives in IRB review. Participants also described efforts to educate and build relationships with key stakeholders as important features of a high-quality HRPP. While generally satisfied with their approaches, participants expressed concern about resource and time constraints that pushed them to be reactive and automatic about QEE, rather than proactive and critical.Conclusions The relevant AAHRPP accreditation standard may obscure critical gaps in defining and measuring QEE elements. We recommend that AAHRPP: (1) offer a definition of QEE or require accredited organizations to provide their own, to help clarify the rationale and goals behind assessment and improvement efforts, and (2) require accredited organizations to establish QEE objectives and measures focused on participant outcomes and deliberative quality during protocol review.

Gene–environment covariance is the phenomenon whereby genetic differences bias variation in developmental environment, and is particularly problematic for assigning genetic and environmental causation in a heritability analysis. The interpretation of these cases has differed amongst biologists and philosophers, leading some to reject the utility of heritability estimates altogether. This paper examines the factors that influence causal reasoning when G–E covariance is present, leading to interpretive disagreement between scholars. It argues that the causal intuitions elicited are influenced by concepts of agency (...) and blame-worthiness, and are intimately tied with the conceptual understanding of the phenotype under investigation. By considering a phenotype-specific approach, I provide an account as to why causal ascriptions can differ depending on the interpreter. Phenotypes like intelligence, which have been the primary focus of this debate, are more likely to spark disagreement for the interpretation of G–E covariance cases because the concept and ideas about its ‘normal development’ relatively ill-defined and are a subject of debate. I contend that philosophical disagreement about causal attributions in G–E covariance cases are in essence disagreements regarding how a phenotype should be defined and understood. This moves the debate from one of an ontological flavour concerning objective causal claims, to one concerning the conceptual, normative and semantic dependencies. (shrink)

This paper responds to recent work in the philosophy of Homotopy Type Theory by James Ladyman and Stuart Presnell. They consider one of the rules for identity, path induction, and justify it along ‘pre-mathematical’ lines. I give an alternate justification based on the philosophical framework of inferentialism. Accordingly, I construct a notion of harmony that allows the inferentialist to say when a connective or concept is meaning-bearing and this conception unifies most of the prominent conceptions of harmony through category theory. (...) This categorical harmony is stated in terms of adjoints and says that any concept definable by iterated adjoints from general categorical operations is harmonious. Moreover, it has been shown that identity in a categorical setting is determined by an adjoint in the relevant way. Furthermore, path induction as a rule comes from this definition. Thus we arrive at an account of how path induction, as a rule of inference governing identity, can be justified on mathematically motivated grounds. (shrink)

In the 1980s, philosophical, historical and social studies of science underwent a change which later evolved into a turn to practice. Analysts of science were asked to pay attention to scientific practices in meticulous detail and along multiple dimensions, including the material, social and psychological. Following this turn, the interest in scientific practices continued to increase and had an indelible influence in the various fields of science studies. No doubt, the practice turn changed our conceptions and approaches of science, but (...) what did it really teach us? What does it mean to study scientific practices? What are the general lessons, implications, and new challenges? This volume explores questions about the practice turn using both case studies and theoretical analysis. The case studies examine empirical and mathematical sciences, including the engineering sciences. The volume promotes interactions between acknowledged experts from different, often thought of as conflicting, orientations. It presents contributions in conjunction with critical commentaries that put the theses and assumptions of the former in perspective. Overall, the book offers a unique and diverse range of perspectives on the meanings, methods, lessons, and challenges associated with the practice turn. (shrink)

Why do humans make music? Theories of the evolution of musicality have focused mainly on the value of music for specific adaptive contexts such as mate selection, parental care, coalition signaling, and group cohesion. Synthesizing and extending previous proposals, we argue that social bonding is an overarching function that unifies all of these theories, and that musicality enabled social bonding at larger scales than grooming and other bonding mechanisms available in ancestral primate societies. We combine cross-disciplinary evidence from archeology, anthropology, (...) biology, musicology, psychology, and neuroscience into a unified framework that accounts for the biological and cultural evolution of music. We argue that the evolution of musicality involves gene–culture coevolution, through which proto-musical behaviors that initially arose and spread as cultural inventions had feedback effects on biological evolution because of their impact on social bonding. We emphasize the deep links between production, perception, prediction, and social reward arising from repetition, synchronization, and harmonization of rhythms and pitches, and summarize empirical evidence for these links at the levels of brain networks, physiological mechanisms, and behaviors across cultures and across species. Finally, we address potential criticisms and make testable predictions for future research, including neurobiological bases of musicality and relationships between human music, language, animal song, and other domains. The music and social bonding hypothesis provides the most comprehensive theory to date of the biological and cultural evolution of music. (shrink)

"'There is only one thing that is certain, namely that we can have nothing certain; and therefore it is not certain that we can have nothing certain,' Samuel Butler once said, expressing in that mindbloggler all the elements required to form a classical paradox.

This modern, advanced textbook reviews modal logic, a field which caught the attention of computer scientists in the late 1970's.

A popular and enduring approach to the liar paradox takes the concept of truth to be inconsistent. Very roughly, truth is an inconsistent concept if the central principles of this concept (taken together) entail a contradiction, where one of these central principles is Tarski's T-schema for truth: a sentence S is true if and only if p, (where S says that p). This article targets a version of Inconsistentism which: retains classical logic and bivalence; takes the truth-predicate “is true” to (...) pick out a property (and determine a non-empty extension relative to a given world); and holds that liar sentences exhibit a certain kind of indeterminacy in truth-value. Call such a view Modest Inconsistentism since it is somewhat more conservative in its outlook than various other forms of Inconsistentism. Such a modest view has its attractions: we retain the thesis that the liar sentence is meaningful; we get to respect the claims that there are truths and that there is a property of truth; we get to keep classical logic and bivalence; and, prima facie, no strengthened liar paradox is in the offing. The main aim in this paper is to show that Modest Inconsistentism, despite its initial attractions, is in deep trouble—because it does, after all, give rise to a strengthened liar paradox. We shall also see that there are related kinds of theory which are also subject to the same worry. (shrink)

Inductively defined structures are ubiquitous in mathematics; their specification is unambiguous and their properties are powerful. All fields of mathematical logic feature these structures prominently: the formula of a language, the set of theorems, the natural numbers, the primitive recursive functions, the constructive number classes and segments of the cumulative hierarchy of sets. -/- This dissertation gives a mathematical characterization of a species of inductively defined structures, called accessible domains, which include all of the above examples except the set of (...) theorems. The concept of an accessible domain comes from Wilfried Sieg's analysis of proof-theoretic practices, starting with his dissertation. In particular, he noticed the special epistemological character of elements of an accessible domain: they can always be uniquely identified with their build-up. Generally, the unique build-up of elements justifies the principles of induction and recursion. -/- I use category theory to give an abstract characterization of accessible domains. I claim that accessible domains are all instances of initial algebras for endofunctors. Grounded in the historical roots of Sieg's discussions, this dissertation shows how the properties of initial algebras for endofunctors and accessible domains coincide in a satisfying and natural way. -/- Filling out this characterization, I show how important examples of accessible domains fit into this broad characterization. I first characterize some accessible domains by relatively simple functors (e.g. finite, polynomial, those that preserve certain colimits) where we can see how iterating the functor can produce the accessible domain. Then I describe accessible domains that result from more involved specifications (e.g. ordinals and segments of the cumulative hierarchies associated with CZF, IZF, and ZF) by relying heavily on algebraic set theory. I end with a discussion of some of the methodological features of category theory in particular that helped characterize accessible domains. (shrink)
