This essay explores the role of informal logicand its application in the context of currentdebates regarding evidence-based medicine. This aim is achieved through a discussion ofthe goals and objectives of evidence-basedmedicine and a review of the criticisms raisedagainst evidence-based medicine. Thecontributions to informal logic by StephenToulmin and Douglas Walton are explicated andtheir relevance for evidence-based medicine isdiscussed in relation to a common clinicalscenario: hypertension management. This essayconcludes with a discussion on the relationshipbetween clinical reasoning, rationality, andevidence. It is argued that (...) informal logic hasthe virtue of bringing explicitness to the roleof evidence in clinical reasoning, and bringssensitivity to understanding the role ofdialogical context in the need for evidence inclinical decision making.

My dissertation is a systematic defense of the claim that what it is to be rational is to correctly respond to the reasons you possess. The dissertation is split into two parts, each consisting of three chapters. In Part I--Coherence, Possession, and Correctly Responding--I argue that my view has important advantages over popular views in metaethics that tie rationality to coherence (ch. 2), defend a novel view of what it is to possess a reason (ch. 3), and defend a novel (...) view about what it is to act and hold attitudes for normative reasons (ch. 4). In Part II--Foundationalism, Deception, and The Importance of Being Rational--I argue that foundationalists about epistemic rationality should think that the foundational beliefs are held for sufficient reasons (ch. 5), argue that my view solves the New Evil Demon problem for externalism (and solves a related and underapprieciated problem) (ch. 6), and argue that my view can vindicate the thought that we ought to be rational (ch. 7).

Errol Lord explores the boundaries of epistemic normativity. He argues that we can understand these better by thinking about which mental states are competitors in rationality’s competition. He argues that belief, disbelief, and two kinds of suspension of judgment are competitors. Lord shows that there are non-evidential reasons for suspension of judgment. One upshot is an independent motivation for a certain sort of pragmatist view of epistemic rationality.

Errol Lord offers a new account of the nature of rationality: what it is for one to be rational is to correctly respond to the normative reasons one possesses. Lord defends novel views about what it is to possess reasons and what it is to correctly respond to reasons, and dispels doubts about whether we ought to be rational.

Objectivists about obligation hold that obligations are determined by all of the normatively relevant facts. Perspectivalists, on the other hand, hold that only facts within one’s perspective can determine what we are obligated to do. This chapter argues for a perspectivalist view. It argues that what you are obligated to do is determined by the normative reasons you possess. This view is anchored in the thought that our obligations have to be action-guiding in a certain sense—we have to be able (...) to act for the reasons that obligate us. The chapter argues that we have this ability—the ability to act for the right reasons—only if we possess those reasons. Thus, objectivism is false. The second half of the chapter argues that problems having to do with new information do not plague the particular perspectival view presented. (shrink)

It is a truism that we ought to be rational. Despite this, it has become popular to think that it is not the case that we ought to be rational. In this paper I argue for a view about rationality—the view that what one is rationally required to do is determined by the normative reasons one possesses—by showing that it can vindicate that one ought to be rational. I do this by showing that it is independently very plausible that what (...) one ought to do is determined by the normative reasons one possesses. Thus, the paper also makes a contribution tos the debate about the nature of our obligations. (shrink)

It’s an undeniable fact about our moral lives that we are partial towards certain people and projects. Despite this, it has traditionally been very hard to justify partiality. In this paper I defend a novel partialist theory. The context of the paper is the debate between three different views of how partiality is justified. According to the first view, partiality is justified by facts about our ground projects. According to the second view, partiality is justified by facts about our relationships (...) with the things that we are partial towards. And according to the third view, partiality is justified by facts about the things that we are partial towards. I argue that all three views contain part of the truth. We can see this by adopting a more sophisticated view of the weight of reasons. Once we do this, it will be clear that both facts about individuals and facts about relationships play a role in explaining why we often have stronger reason to act well towards those things we are partial towards. Further, I argue, facts about projects help explain why facts about relationships play the role that they do in determining the strength of our reasons. (shrink)

Normative reasons have become a popular theoretical tool in recent decades. One helpful feature of normative reasons is their weight. The fourteen new essays in this book theorize about many different aspects of weight. Topics range from foundational issues to applications of weight in debates across philosophy.

Objectivists about obligation hold that obligations are determined by all of the normatively relevant facts. Perspectivalists, on the other hand, hold that only facts within one's perspective can determine what we are obligated to do. In this paper I argue for a perspectivalist view. On my view, what you are obligated to do is determined by the normative reasons you possess. My argument for my view is anchored in the thought that our obligations have to be action-guiding in a certain (...) sense--we have to be able to act for the reasons that obligate us. I argue that we have this ability--the ability to act for the right reasons--only if we possess those reasons. Thus, objectivism is false. In the second half of the paper I argue that problems having to do with new information do not plague my particular perspectival view. (shrink)

There are parallel debates in metaethics and aesthetics about the rational merits of deferring to others about ethics and aesthetics. In both areas it is common to think that there is something amiss about deference. A popular explanation of this in aesthetics appeals to the importance of aesthetic acquaintance. This kind of explanation has not been explored much in ethics. This chapter defends a unified account of what is amiss about ethical and aesthetic deference. According to this account, deference is (...) a non-ideal way of thinking about ethics and aesthetics because it does not allow us to possess the full range of reasons provided by the ethical and aesthetic facts. It has this feature because it does not acquaint us with ethical and aesthetic facts. It is argued further that despite this defect, there is no general obligation not to defer. The upshot is a moderate optimism about ethical and aesthetic deference. (shrink)

Investigates Aristotle's views on the ontological status of artifacts in the Metaphysics, with implications for a variety of metaphysical problems.

It is often assumed that believing that p for a normative reason consists in nothing more than (i) believing that p for a reason and (ii) that reason’s corresponding to a normative reason to believe that p, where (i) and (ii) are independent factors. This is the Composite View. In this paper, we argue against the Composite View on extensional and theoretical grounds. We advocate an alternative that we call the Prime View. On this view, believing for a normative reason (...) is a distinctive achievement that isn’t exhausted by the mere conjunction of (i) and (ii). Its being an achievement entails that (i) and (ii) are not independent when one believes for a normative reason: minimally, (i) must hold because (ii) holds. Apart from its intrinsic interest, our discussion has important upshots for central issues in epistemology, including the analysis of doxastic justification, the epistemology of perception, and the place of competence in epistemology.

It’s natural to say that when it’s rational for me to φ, I have reasons to φ. That is, there are reasons for φ-ing, and moreover, I have some of them. Mark Schroeder calls this view The Factoring Account of the having reasons relation. He thinks The Factoring Account is false. In this paper, I defend The Factoring Account. Not only do I provide intuitive support for the view, but I also defend it against Schroeder’s criticisms. Moreover, I show that (...) it helps us understand the requirements of substantive rationality, or what we are rationally required to do when responding to reasons. (shrink)

The post-Gettier literature contained many views that tried to solve the Gettier problem by appealing to the notion of defeat. Unfortunately, all of these views are false. The failure of these views greatly contributed to a general distrust of reasons in epistemology. However, reasons are making a comeback in epistemology, both in general and in the context of the Gettier problem. There are two main aims of this paper. First, I will argue against a natural defeat based resolution of the (...) Gettier problem. Second, I will defend my own defeat based solution. This solution appeals to a modal anti-luck condition. I will argue that this condition captures anti-luck intuitions and has virtues that rival modal anti-luck conditions lack. (shrink)

In this paper I'm interested in the prospects for the Right Reasons theory of creditworthiness. The Right Reasons theory says that what it is for an agent to be creditworthy for X-ing is for that agent to X for the right reasons. The paper has a negative goal and a positive goal. The negative goal is to show that a class of Right Reasons theories are doomed. These theories all have a Conceptualization Condition on acting for the right reasons. Conceptualization (...) Conditions demand that agents who act for the right reasons deploy or be able to deploy certain normative concepts in acting. I argue that views of this type run into a host of overintellectualization problems. The positive aim is to argue for my Right Reasons view, which appeals to know-how to avoid overintellectualization. (shrink)

Conciliationists about peer disagreement hold that when one disagrees with an epistemic peer about some proposition p, one should significantly change one's view about p. Many arguments for conciliationism appeal to a principle Christensen [2011] dubs Independence. Independence says that evaluations of the beliefs of those with whom one disagrees should not be made on the basis of one's initial reasoning about p. In this paper, I show that this principle is false. I also show that two weaker principles that (...) vindicate conciliationism are either false, unmotivated, or both. (shrink)

Reasons fundamentalists maintain that we can analyze all derivative normative properties in terms of normative reasons. These theorists famously encounter the Wrong Kind of Reasons problem, since not all reasons for reactions seem relevant for reasons-based analyses. Some have argued that this problem is a general one for many theorists, and claim that this lightens the burden for reasons fundamentalists. We argue in this paper that the reverse is true: the generality of the problem makes life harder for reasons fundamentalists. (...) We do this in two stages. First, we show that reflection on the generality of the distinction between wrong-kind reasons and right-kind reasons shows that not all right-kind reasons are normative reasons. So, not only do reasons-based analyses require a distinction between right-kind reasons and wrong-kind reasons, they also need a distinction between normative right-kind reasons from nonnormative right-kind reasons. We call this the Right Kind of Reasons Problem. In the second stage of the paper, we argue that reasons fundamentalism places tight constraints on its proper solution: in particular, it forbids one from appealing to anything normative to distinguish normative RKRs from nonnormative RKRs. It hence seems that reasons fundamentalists can only appeal to natural facts to solve the problem, but it is unclear which ones can do the job. So, reflection on the generality of the distinction only multiplies the fundamentalist’s problems. We end by exploring several solutions to these problems, and recommend a form of constitutivism as the best. (shrink)

Normative theory aims to understand the commonalities between ethics, prudence, epistemology, aesthetics and political philosophy (among others). One central question in normative theory is what is fundamental to the normative. The reasons-first approach holds that normative reasons are fundamental to the normative domain. This view has been challenged by proponents of alternative X-first views such as value, fittingness and ought. This paper examines the debate about the analysis of normative reasons and argues for a new form of reductive naturalism that (...) analyses normative reasons in terms of fittingness, ought and value. I argue that this view is compatible with Reasons First because fittingness and the type of ought and value appealed to are not robustly normative notions. It is also extensionally and explanatorily plausible, and thus has much to recommend it on both first-order and second-order grounds. (shrink)

You are irrational when you are akratic. On this point most agree. Despite this agreement, there is a tremendous amount of disagreement about what the correct explanation of this data is. Narrow-scopers think that the correct explanation is that you are violating a narrow-scope conditional requirement. You lack an intention to x that you are required to have given the fact that you believe you ought to x. Wide-scopers disagree. They think that a conditional you are required to make true (...) is false. You aren’t required to have any particular attitudes. You’re just required to intend to x or not believe you ought to x. Wide-scope accounts are symmetrical insofar as they predict that you are complying with the relevant requirement just so long as the relevant conditional is true. Some narrow-scopers object to this symmetry. However, there is disagreement about why the symmetry is objectionable. This has led wide-scopers to defend their view against a number of different symmetry objections. I think their defenses in the face of these objections are, on the whole, plausible. Unfortunately for them, they aren’t defending their view against the best version of the objection. In this paper I will show that there is a symmetry objection to wide-scope accounts that both hasn’t been responded to and is a serious problem for wide-scope accounts. Moreover, my version of the objection will allow us to see that there is at least one narrow-scope view that has been seriously underappreciated in the literature. (shrink)

Can one know aesthetic facts on the basis of testimony? Optimists say that we can. Pessimists say that we cannot. Daniel Whiting has recently put forth a new argument for pessimism about the epistemic power of aesthetic testimony. He seeks to establish pessimism by arguing that testimonial beliefs cannot justify the downstream reactions that would otherwise be justified if one had aesthetic knowledge. In this paper, I will show that there is a plausible alternative explanation of the data that Whiting (...) appeals to. The views that provide this explanation are not only compatible with optimism, but they also provide a nice explanation of why it is plausible that we often know aesthetic facts on the basis of testimony.

It is a truism that agents can do the right action for the right reason. To put the point in terms more familiar to ethicists, it is a truism that one’s motivating reason can be one’s normative reason. In this short note, I will argue that Jonathan Dancy’s preferred view about how this is possible faces a dilemma. Dancy has the choice between accounting for two plausible constraints while at the same time holding an outlandish philosophy of mind by his (...) own lights or giving up his view's central tenet. At the end, I will suggest a view similar to Dancy’s that avoids the dilemma. (shrink)

Harris elucidates the important philosophical implications of the Anthropic Principle. Tracing the continuous development of the principle from physics through biology and psychology, he examines the case for the thesis that intelligent life is necessarily involved from the very beginning of physical reality and that the entire process of natural evolution comes to consciousness of itself in the human mind.

Eukaryotic cells are able to mount several genetically complex cellular responses to DNA damage. The yeast Saccharomyces cerevisiae is a genetically well characterized organism that is also amenable to molecular and biochemical studies. Hence, this organism has provided a useful and informative model for dissecting the biochemistry and molecular biology of DNA repair in eukaryotes.

It is generally agreed that many types of attitudinal incoherence are irrational, but there is controversy about why they are. Some think incoherence is irrational because it violates certain wide-scope conditional requirements, others (‘narrow-scopers’) that it violates narrow-scope conditional requirements. In his paper ‘The Scope of Rational Requirements’, John Brunero has offered a putative counter-example to narrow-scope views. But a narrow-scoper should reject a crucial assumption which Brunero makes, namely, the claim that we always violate conditional narrow-scope requirements when we (...) do not comply with them. I show how Brunero's objection can be met by denying this claim, and I provide independent arguments in favour of denying it. (shrink)

This paper examines whether corporate environmental responsibility is influenced by regional differences in climate change denial. While there is an overwhelming consensus among scientists that climate change is happening, recent surveys still indicate widespread climate change denial across societies. Given that corporate activity causing climate change is fundamentally rooted in individual beliefs and societal institutions, we examine whether local perceptions about climate change matter for firms’ engagement in environmental responsibility. We use climate change perception surveys conducted in the U.S. to (...) compute a novel measure of climate change denial for each U.S. county. We find that firms located in counties with higher levels of climate change denial have weaker environmental performance ratings, are more likely to commit environmental violations, and impose greater environmental costs on society. Regional differences in religiosity, social capital, political leaning, or county-level demographic characteristics cannot explain these results. Furthermore, we document that strong corporate governance mechanisms and corporate culture moderate the negative relationship between climate change denial and corporate environmental responsibility. Overall, our findings offer new insights into how local beliefs and perceptions about climate change may influence firm-level sustainability practices. (shrink)

Cockayne syndrome is a rare autosomal recessive disease characterized by a complex clinical phenotype. Most Cockayne syndrome cells are hypersensitive to killing by ultraviolet radiation. This observation has prompted a wealth of studies on the DNA repair capacity of Cockayne syndrome cells in vitro. Many studies support the notion that such cells are defective in a DNA repair mode(s) that is transcription‐dependent. However, it remains to be established that this is a primary molecular defect in Cockayne syndrome cells and that (...) it explains the complex clinical phenotype associated with the disease. An alternative hypothesis is that Cockayne syndrome cells have a defect in transcription affecting the expression of certain genes, which is compatible with embryogenesis but not with normal post‐natal development. Defective transcription may impair the normal processing of DNA damage during transcription‐dependent repair.‘“Curiouser and curiouser” cried Alice.’ (Lewis Carroll, Alice's Adventures in Wonderland).

McKenzie Seeds is a crown corporation owned by the people of Manitoba. In 1983, the company was rocked by a scandal involving its senior management. During the course of the controversy, George F. MacDowell resigned as chairman of the McKenzie Seeds board of directors. He subsequently wrote a pamphlet which attempted to provide a context for understanding events at McKenzie Seeds. This paper provides a brief history of the company and a discussion of MacDowell's pamphlet. A postscript provides information on (...) some recent developments, which suggests that the issues raised by the scandal and identified in the pamphlet remain unresolved. (shrink)

This sequel to the highly acclaimed "Cosmos and Anthropos" demonstrates the impact on social, ethical, and theological doctrines of the twentieth-century scientific revolution, particularly the Anthropic Principle. Harris reviews the main arguments put forward in the Western philosophical tradition for the existence of God, as well as the critique of those arguments, and shows that the conflict between religion and science since the seventeenth century has resulted more from the implications of the Copernican-Newtonian scientific paradigm than from any insuperable divergence (...) of dogma or ultimate aim.
