When Genotype × Environment (G × E) interactions are present, heritability estimates are not interpretable. Mealey cites abundant evidence for G × E interactions in the etiology of sociopathy, thereby completely undermining estimates of the heritability of sociopathy which form the foundation of her model. Without proper evidence for a genetic basis of sociopathy, Mealey's sociobiological model collapses under its own great weight.

From obnoxious public figures to online trolling and accusations of “fake news”, almost no one seems able to disagree without hostility. But polite discord sounds farfetched when issues are so personal and fundamental that those on opposing sides appear to have no common ground. How do you debate the “enemy”? Philosophers Scott Aikin and Robert Talisse show that disagreeing civilly, even with your sworn enemies, is a crucial part of democracy. Rejecting the popular view that civility requires a polite (...) and concessive attitude, they argue that our biggest challenge is not remaining calm in the face of an opponent, but rather ensuring that our political arguments actually address those on the opposing side. Too often politicians and pundits merely simulate political debate, offering carefully structured caricatures of their opponents. These simulations mimic political argument in a way designed to convince citizens that those with whom they disagree are not worth talking to. Good democracy thrives off conflict, but until we learn the difference between real and simulated arguments we will be doomed to speak at cross-purposes. Aikin and Talisse provide a crash course in political rhetoric for the concerned citizen, showing readers why understanding the structure of arguments is just as vital for a healthy democracy as debate over facts and values. But there’s a sting in the tail - no sooner have we learned rhetorical techniques for better disagreement than these techniques themselves become weapons with which to ignore our enemies, as accusations like “false equivalence” and “ad hominem” are used to silence criticism. Civility requires us to be eternally vigilant to the ways we disagree. (shrink)

An examination of the history and arguments behind W.K. Clifford and William James's landmark essays and subsequent impact on the importance of knowledge-based evidence.

In the last decade, the familiar problem of the regress of reasons has returned to prominent consideration in epistemology. And with the return of the problem, evaluation of the options available for its solution is begun anew. Reason’s regress problem, roughly put, is that if one has good reasons to believe something, one must have good reason to hold those reasons are good. And for those reasons, one must have further reasons to hold they are good, and so a regress (...) of reasons looms. In this new study, Aikin presents a full case for infinitism as a response to the problem of the regress of reasons. Infinitism is the view that one must have a non-terminating chain of reasons in order to be justified. The most defensible form of infinitism, he argues, is that of a mixed theory – that is, epistemic infinitism must be consistent with and integrate other solutions to the regress problem. (shrink)

This paper offers an account of a fallacy we will call bothsiderism, which is to mistake disagreement on an issue for evidence that either a compromise on, suspension of judgment regarding, or continued discussion of the issue is in order. Our view is that this is a fallacy of a unique and heretofore untheorized type, a fallacy of meta-argumentation. The paper develops as follows. After a brief introduction, we examine a recent bothsiderist case in American politics. We use this as (...) a pivot point to survey the theoretical literature on the fallacy. The most prominent theory is that bothsiderism is a case of dialogue-shifting. This view fails, we maintain, to explain how bothsiderism might be persuasive. We argue, rather, bothsiderism is a kind of meta-argumentative fallacy. (shrink)

The Routledge Companion to Pragmatism offers 44 cutting-edge chapters--written specifically for this volume by an international team of distinguished researchers--that assess the past, present, and future of pragmatism. Going beyond the exposition of canonical texts and figures, the collection presents pragmatism as a living philosophical idiom that continues to devise promising theses in contemporary debates. The chapters are organized into four major parts: Pragmatism's History and Figures Pragmatism and Plural Traditions Pragmatism's Reach Pragmatism's Relevance Each chapter provides up-to-date research tools (...) for philosophers, students, and others who wish to locate pragmatist options in their contemporary research fields. As a whole, the volume demonstrates that the vitality of pragmatism lies in its ability to build upon, and transcend, the ideas and arguments of its founders. When seen in its full diversity, pragmatism emerges as one of the most successful and influential philosophical movements in Western philosophy. (shrink)

What follows is a taxonomy of arguments that regresses of inferential justification are vicious. They fall out into four general classes: conceptual arguments from incompleteness, conceptual arguments from arbitrariness, ought-implies-can arguments from human quantitative incapacities, and ought-implies can arguments from human qualitative incapacities. They fail with a developed theory of "infinitism" consistent with valuational pluralism and modest epistemic foundationalism.

Given immunity’s general role in the organism’s economy—both in terms of its internal environment as well as mediating its external relations—immune theory has expanded its traditional formulation of preserving individual autonomy to one that includes accounting for nutritional processes and symbiotic relationships that require immune tolerance. When such a full ecological alignment is adopted, the immune system becomes the mediator of both defensive and assimilative environmental intercourse, where a balance of immune rejection and tolerance governs the complex interactions of the (...) organism’s ecological relationships. Accordingly, immunology, which historically had affiliated with the biology of individuals, now becomes a science concerned with the biology of communities. With this translocation, the ontological basis of the organism is undergoing a profound change. Indeed, the recent recognition of the ubiquity of symbiosis has challenged the traditional notions of biological individuality and requires a shift in the metaphysics undergirding biology, in which a philosophy of the organism must be characterized by ecological dialectics “all-the-way-down.”.

Deep disagreements are disagreements wherein the dialectical conditions for fruitful argumentative exchange do not obtain. One view from within these disagreements is that the other side has been duped or is so deeply ignorant of and complacent with some illusion, there is no hope for exchange. The Dark Enlightenment's critique of liberal democracy and progressive politics (which gave rise to the alt‐right movement) proceeds on this premise, calling their critical philosophy ‘the red pill’ and terming the opposition's program ‘the Cathedral’. (...) Despite the depth of their disagreement with progressives, there is evidence for an optimistic program of critical dialogue in this instance of deep disagreement. (shrink)

Developmental biology is a theory of interpretation. Developmental signals are interpreted differently depending on the previous history of the responding cell. Thus, there is a context for the reception of a signal. While this conclusion is obvious during metamorphosis, when a single hormone instructs some cells to proliferate, some cells to differentiate, and other cells to die, it is commonplace during normal development. Paracrine factors such as BMP4 can induce apoptosis, proliferation, or differentiation depending upon the history of the responding (...) cells. In addition, organisms have evolved to alter their development in response to differences in temperature, diet, the presence of predators, or the presence of competitors. This allows them to develop the phenotype, within the limits imposed by the genotype, best suited for the immediate habitat of the organism. Most developing organisms have also evolved to expect developmental signals from symbionts, and these organisms develop abnormally if the symbiont signals are not present. Thus Hoffmeyer’s “vertical semiotic system” of genetic communication and “horizontal semiotic system” of ecological communication are integrated during development. (shrink)

Arguments are weakly meta-argumentative when they call attention to themselves and purport to be successful as arguments. Arguments are strongly metaargumentative when they take arguments (themselves or other arguments) as objects for evaluation, clarification, or improvement and explicitly use concepts of argument analysis for the task. The ambitious meta-argumentation thesis is that all argumentation is weakly argumentative. The modest meta-argumentation thesis is that there are unique instances of strongly meta-argumentative argument. Here, we show how the two theses are connected and (...) both are plausible. (shrink)

I will assume here the defenses of epistemic infinitism are adequate and inquire as to the variety standpoints within the view. I will argue that infinitism has three varieties depending on the strength of demandingness of the infinitist requirement and the purity of its conception of epistemic justification, each of which I will term strong pure, strong impure, and weak impure infinitisms. Further, I will argue that impure infinitisms have the dialectical advantage.

Although Caenorhabditis elegans was chosen and modified to be an organism that would facilitate a reductionist program for neurogenetics, recent research has provided evidence for properties that are emergent from the neurons. While neurogenetic advances have been made using C. elegans which may be useful in explaining human neurobiology, there are severe limitations on C. elegans to explain any significant human behavior.

My objective in this paper is to compare two philosophical problems, the problem of the criterion and the problem of deep disagreement, and note a core similarity which explains why many proposed solutions to these problems seem to fail along similar lines. From this observation, I propose a kind of skeptical solution to the problem of deep disagreement, and this skeptical program has consequences for the problem as it manifests in political epistemology and metaphilosophy.

The article examines the formal properties of Romeo and Juliet's encounter-sonnet, and suggests that Shakespeare included the sonnet for readers he hoped would be repeat play-goers. There are two parts of the case: 1) The first part takes up Romeo and Juliet's first encounter and examines it as a sonnet, orienting the analysis of its poetics through a historicized understanding of poetic form, book culture and theatrical performance; 2) the second asks how a member of Shakespeare's own play audience would (...) have known that the sonnet is one, arguing that s/he might not have without having read the play beforehand. The relationship between quarto-reading and play-going perhaps encouraged audiences to see the play again after reading it. The article concludes by defending the return to form in Shakespeare Studies. (shrink)

The debate over the possibility of Christian philosophy remains largely intractable because of the modern assumption of a sharp distinction between philosophy and theology. The metaphysical basis of this assumption is an understanding of the world's relationship to God that emphasizes efficient causality and thus introduces a hiatus between the world and God. This contrastive understanding of transcendence parallels insistence on the disciplinary distinction between philosophy and theology. ;St. Gregory Palamas , in his two major works, the Triads and One (...) Hundred and Fifty Chapters, articulates a metaphysics according to which all beings participate in God as their formal principle. This metaphysics maintains God's transcendence in a non-contrastive manner such that it coincides with divine immanence. The possibility to be explored is whether this metaphysics may support an alternative approach to the Christian philosophy debate. ;In Chapter One I argue that the prevailing, anti-philosophical reading of Palamas is misled by his rhetoric and therefore fails to recognize that the target of his criticism is not philosophy in general, but a nascent Byzantine modernism. Chapter Two details the nature of this target as presented by Palamas's main opponent, Barlaam of Calabria. In Chapter Three I examine the metaphysics of participation, which presents the coincidence of transcendence and immanence that is the basis both of Palamas's well-known distinction between God's ousia and activities and of Palamas's radical Dionysian apophaticism. ;In Chapter Four I develop the implication of this metaphysics: the world is radically and thoroughly theophanic or symbolic. The proper comportment of one's soul before such a reality must be contemplative. Therefore, I argue in Chapter Five, the soul must be transformed by the spiritual exercises that constitute philosophy as such a way of life. For Palamas, philosophy is intrinsically constituted by the soul's eros for God. In Chapter Six I argue that once philosophy is understood in this way, the assumed disciplinary distinction between philosophy and theology disappears. Palamas's antimodern stance, then, undermines the modern presuppositions of the Christian philosophy debate and thus may provide an alternative solution. (shrink)

In this paper, I argue for three theses. First, that the problem of Deep Disagreement is usefully understood as an instance of the skeptical Problem of the Criterion. Second, there are structural similarities between proposed optimistic answers to deep disagreement and the problem of the criterion. Third, in light of these similarities, there are both good and bad consequences for proposed solutions to the problem of deep disagreement.

The straw man fallacy consists in inappropriately constructing or selecting weak versions of the opposition’s arguments. We will survey the three forms of straw men recognized in the literature, the straw, weak, and hollow man. We will then make the case that there are examples of inappropriately reconstructing stronger versions of the opposition’s arguments. Such cases we will call iron man fallacies. The difference between appropriate and inappropriate iron manning clarifies the limits of the virtue of open-mindedness.

Free speech fallacies are errors of meta-argument. One commits a free speech fallacy when one argues that since there are apparent restrictions on one’s rights of free expression, procedural rules of critical exchange have been broken, and consequently, one’s preferred view is dialectically better off than it may otherwise seem. Free speech fallacies are meta-argumentative, since they occur at the level of assessing the dialectical situation in terms of norms of argument and in terms of meta-evidential principles of interpreting how (...) and why people follow (or fail to follow) argumentative rules. Our plan here is to begin with a brief explanation of meta-argument and meta-argumentative fallacy. We will then turn to the variety of forms of the free speech fallacy, which we will explain as meta-argumentatively erroneous. (shrink)

The theistic argument from beauty has what we call an 'evil twin', the argument from ugliness. The argument yields either what we call 'atheist win', or, when faced with aesthetic theodicies, 'agnostic tie' with the argument from beauty.

Why We Argue : A Guide to Political Disagreement in an Age of Unreason presents an accessible and engaging introduction to the theory of argument, with special emphasis on the way argument works in public political debate. The authors develop a view according to which proper argument is necessary for one's individual cognitive health; this insight is then expanded to the collective health of one's society. Proper argumentation, then, is seen to play a central role in a well-functioning democracy. Written (...) in a lively style and filled with examples drawn from the real world of contemporary politics, and questions following each chapter to encourage discussion, Why We Argue reads like a guide for the participation in, and maintenance of, modern democracy. An excellent student resource for courses in critical thinking, political philosophy, and related fields, Why We Argue is an important contribution to reasoned debate. What's New in the Second Edition: Updated examples throughout the book, including examples from the 2016 U.S. election and first years of the Trump presidency; Expanded coverage of dialectical fallacies, including coverage of new types of fallacies and of sites where such fallacies thrive ; Revised For Further Thought questions and definitions of Key Terms, included at the end of each chapter; The addition of five new chapters: Deep Disagreement Argument by Analogy Argument between the Ads The Owl of Minerva Argumentative Responsibility and Repair.

In lieu of an abstract, here is a brief excerpt of the content:Perelmanian Universal Audience and the Epistemic Aspirations of ArgumentScott F. AikinIThe notion of universality in argumentation is as fecund as is it is controversial. Chaïm Perelman and Lucie Olbrechts-Tyteca’s notion of universal audience (UA), given their requirement that all arguments be evaluated in terms of their audiences, clearly promises a rich account of argumentative norms. It equally yields a variety of questions. For the most part, the questions come (...) in three forms: what, precisely, is the universal audience; whether it is, in the end, a coherent notion; and how its norms actually constrain argument. Many objections to the notion claim that it is either incoherent or too empty to constrain. My objective here is to provide an account of Perelman’s notion of UA that avoids these objections. I will argue that the UA can be clarified with a distinction between two functions it plays in argumentation— one pragmatic and another epistemic. Perelman and Olbrechts-Tyteca do not explicitly disambiguate these roles themselves, though they do use the notion in two distinct ways in The New Rhetoric (TNR [1969]), and so it seems clear that although the view in the end may be Perelmanian, it is arguably not Perelman’s. No matter. The purpose of this essay is not to exhume Perelman but to resurrect and exercise his views. That is, historical work in philosophy must straddle the demands of two distinct goals— fidelity to the author in question and defensibility of the views developed. My case [End Page 238] will jointly depend on the comparative plausibility of my account as an interpretation of Perelman’s universal audience and of the view as correct regarding argumentative norms in relation to the other competing interpretations of Perelman’s UA. So if my argument for a divided universal audience is at least Perelmanian in spirit, and if it survives the objections to UA that other interpretations do not survive, it should be the philosophically preferable interpretation.IIThe first principle of Perelmanian rhetoric is that arguments are addressed to audiences for the purpose of inducing or increasing adherence to a view (TNR, 14). Consequently, the less reliant arguments are on a specific audience’s idiosyncratic commitments, the more effective the arguments will be in generating assent and resolving disagreements in wider and wider groups of people. Perelman describes the universal audience in The Realm of Rhetoric (RR [1982]) as “itself... made up of an infinite variety of particular audiences” (14). The UA is the regulative ideal of maximal intersubjective agreement. That is, we see both the relative weakness of arguments that depend on the commitments of particular audiences and “the value attached to opinions that enjoy unanimous approval” (TNR, 31). This unanimity is reached at its highest point in the universal audience. As such, UA is an agglomerative notion that functions as a criterion for how widely an argument may be given credence. Call this trajectory toward unanimity the pragmatic element of UA.However, the universal audience’s assent is used to define facts for arguments, and as such, it is a marker of the objectivity of a conclusion, not just the breadth of the effectiveness of an argument. Perelman and Olbrechts-Tyteca stipulate that “from the standpoint of argumentation, we are confronted with a fact only if we can postulate uncontroverted, universal agreement with respect to it” (TNR, 67). Facts and truths are defined in terms of the “agreement of the universal audience” (TNR, 67). This, of course, is not to say that arguments make facts but, instead, that their universal acceptability is a criterion for whether some purported fact is or is not the case. Agreement on this level does not play a metaphysical role of explanation but, rather, a cognitive role of justification for taking a commitment as a premise for further argument. The agreement in a universal audience, further, must be uncontroverted, which means that this UA must have some shared commitment that survives scrutiny (or at least is [End Page 239] not defeated): “The agreement of a universal audience is... a matter, not of fact, but of right” (TNR, 31). And further, this right has a very powerful normative element: “Argumentation... (shrink)

Developmental biology is expanding into several new areas. One new area of study concerns the production of adult-onset phenotypes by exposure of the fetus or neonate to environmental agents. These agents include maternal nutrients, developmental modulators (endocrine disruptors), and maternal care. In all three cases, a major mechanism for the generation of the altered phenotype is chromatin modification. Nutrient conditions, developmental modulators, and even maternal care appear to alter DNA methylation and other associated changes in chromatin that regulate gene expression. (...) This brings a new, under-appreciated, dimension of gene regulation into developmental biology, and it also demonstrates the poverty of the nature versus nurture framework for discussing phenotype production. Moreover, while such epigenetic mechanisms undermine genetic determinism, they add a layer of probabilistic biological causality for the maintenance of social inequalities. (shrink)

Embryology is an intensely visual field, and it has provided the public with images of human embryos and fetuses. The responses to these images can be extremely powerful and personal, and the images (as well as our reactions to them) are conditioned by social and political agendas. The image of the 'autonomous fetus' abstracts the fetus from the mother, the womb, and from all social contexts, thereby emphasizing 'individuality'. The image of 'sacred DNA' emphasizes DNA as the unmoved mover, the (...) eidos, the soul of the human being. Since fertilization involves the forming of a new constellation of DNA in the zygote, the act of fertilization is being perceived as the secular and technical equivalent of ensoulment. This privileges fertilization above the other possible scientifically valued times when 'human life' begins. (shrink)

In this paper, I will argue for a complex of three theses. First, that the problem of deep disagreement is an instance of the regress problem of justification. Second, that the problem of deep disagreement, as a regress problem, depends on a dialecticality requirement for arguments. Third, that the dialecticality requirement is plausible and defensible.

This essay summarizes the research program developed in our new book, Why We Argue (And How We Should): A Guide to Political Disagreement (Routledge, 2014). Humans naturally want to know and to take themselves as having reason on their side. Additionally, many people take democracy to be a uniquely proper mode of political arrangement. There is an old tension between reason and democracy, however, and it was first articulated by Plato. Plato’s concern about democracy was that it detached political decision (...) from reason. Epistemic democrats attempt to show how the two can be re-attached. What is necessary is to couple the core democratic liberties with norms of rational exchange. Thus epistemology and argument provides a basis for democratic politics. Why We Argue (And How We Should) makes a case for the connection and develops a toolkit for maintaining it. (shrink)

A common argument for evidentialism is that the norms of assertion, specifically those bearing on warrant and assertability, regulate belief. On this assertoric model of belief, a constitutive condition for belief is that the believing subject take her belief to be supported by sufficient evidence. An equally common source of resistance to these arguments is the plausibility of cases in which a speaker, despite the fact that she lacks warrant to assert that p, nevertheless attributes to herself the belief that (...) p. In the following, I will outline a variety of ways a speaker may contrastively attribute a belief to herself. In light of what these contrastive statements communicate, cases of attributing beliefs with little or no warrant to oneself offer no substantive counter-example to the evidentialist argument from assertion.

Pragmatism’s naturalism is inconsistent with the phenomenological tradition’s anti-naturalism. This poses a problem for the methodological consistency of phenomenological work in the pragmatist tradition. Solutions such as phenomenologizing naturalism or naturalizing phenomenology have been proposed, but they fail. As a consequence, pragmatists and other naturalists must answer the phenomenological tradition’s criticisms of naturalism.

Xenophanes famously noted that if horses could draw, they would draw their gods as horses. This connection between those who depict the gods and how the gods are depicted is posed as part of a critical theological program. What follows is an argumentative reconstruction of how these observations determine the extent and content of Xenophanes’ theological reforms. In light of the strength of the critical epistemic program, it is likely Xenophanes posed ambitious theological reforms.
