Do university ethics classes influence students’ real-world moral choices? We aimed to conduct the first controlled study of the effects of ordinary philosophical ethics classes on real-world moral choices, using non-self-report, non-laboratory behavior as the dependent measure. We assigned 1332 students in four large philosophy classes to either an experimental group on the ethics of eating meat or a control group on the ethics of charitable giving. Students in each group read a philosophy article on their assigned topic and optionally (...) viewed a related video, then met with teaching assistants for 50-minute group discussion sections. They expressed their opinions about meat ethics and charitable giving in a follow-up questionnaire (1032 respondents after exclusions). We obtained 13,642 food purchase receipts from campus restaurants for 495 of the students, before and after the intervention. Purchase of meat products declined in the experimental group (52% of purchases of at least $4.99 contained meat before the intervention, compared to 45% after) but remained the same in the control group (52% both before and after). Ethical opinion also differed, with 43% of students in the experimental group agreeing that eating the meat of factory farmed animals is unethical compared to 29% in the control group. We also attempted to measure food choice using vouchers, but voucher redemption rates were low and no effect was statistically detectable. It remains unclear what aspect of instruction influenced behavior. (shrink)

Are Confucian and Buddhist ethical views closer to Kantian, Consequentialist, or Virtue Ethical ones? And how can such comparisons shed light on the unique aspects of Confucian and Buddhist views? This essay (i) provides a historically grounded framework for distinguishing western views, (ii) identifies a series of questions that we can ask in order to clarify the philosophic accounts of ethical motivation embedded in the Buddhist and Confucian traditions, and (iii) then critiques Lee Ming-huei’s claim that Confucianism is closer to (...) Kantianism than virtue ethics and Charles Goodman’s claim that Buddhism is closer to Consequentialism than virtue ethics. (shrink)

After distinguishing three conceptions of virtue and its impact on ordinary attachments to external goods such as social status, power, friends, and wealth, this paper argues that the Confucian Analects is most charitably interpreted as endorsing the wholehearted internalization conception, on which virtue reforms but does not completely extinguish ordinary attachments to external goods. I begin by building on Amy Olberding’s attack on the extinguishing attachments conception, but go on to criticize her alternative, resolute sacrifice conception, on which the virtuous (...) retain their ordinary attachments to external goods but are able to master them and willingly settle for virtue. I argue that we should reject this view because, unlike the wholehearted internalization conception, it cannot capture the facts that virtue silences or attenuates attachment to viciously obtained external goods and that virtue grounds positive emotional and cognitive self-assessments that are incompatible with some ordinary attachments to external goods. (shrink)

Building on work by Steve Darwall, I argue that standard virtue ethical accounts of moral motivation are defective because they don't include accounts of social morality. I then propose a virtue ethical account of social morality, and respond to one of Darwall's core objections to the coherence of any such (non-Kantian) account.

This paper concerns the central virtue ethical thesis that the ethical quality of an agent's actions is a function of her dispositional character. Skeptics have rightly urged us to distinguish between an agent's particular intentions or occurrant motives and dispositional facts about her character, but they falsely contend that if we are attentive to this distinction, then we will see that the virtue ethical thesis is false. In this paper I present a new interpretation and defense of the virtue ethical (...) thesis and show how to rebuff the skeptical attacks advanced by Thomas Hurka, Julia Markovits, and Roger Crisp. The key, I contend, is for virtue ethicists to adopt an embodied value conception of character instead of the aretaic trait conception suggested by Aristotle. (shrink)

This book is a methodological guide for the emerging, interdisciplinary science of virtue traits and their value. The authors situate this emerging empirical field in the history of psychology, critically survey existing work, defend the scientific validity of virtue science, and develop a general model that can guide, unify, and catalyze future research. In addition, chapters discuss how philosophy and philosophers can contribute to empirical inquiry and how a mature science of virtue could inform moral philosophy. The book is co-authored (...) by two psychologists and a philosopher who pursued joint empirical work on fairness and then began to discuss larger methodological issues raised by that collaboration. -/- o Expected publication date: January 31, 2024 o Paperback ISBN: 1108747981.

This paper defends a new, role-differentiated account of the virtues of compassion. My main thesis is that in order to understand compassion’s value and advance debate about its ethical importance we need to recognize that the virtue of compassion involves substantively different dispositions and attitudes in different spheres of life – for example in our personal, professional, and civic lives. In each sphere, compassion is an apt and distinctive form of good-willed responsiveness to the value of living beings and their (...) characteristic struggles to live good lives, but the relevant forms of good-willed responsiveness vary because in different contexts there are different types of living beings involved and different relations between the compassionate person and the being to whom she is compassionate. My specific focus is on compassion in human relations; I argue that, in different role and relationship contexts, the virtues of compassion involve different forms of good-willed responsiveness to human struggles to live well. In developing my account I critically engage with the emotion-focused accounts defended by Martha Nussbaum and Roger Crisp and explain how my more plausible account can shed light on the nature and value of compassion for oneself.

This article discusses the vice of self-centeredness, argues that it inhibits our ability to treat humanity as an end in itself, and that Kantian moral theory cannot account for this fact. After in this way arguing that Kantian theory fails to provide a fully adequate account of agents who live up to the formula of humanity, I discuss Buddhist resources for developing a better account.

Adding to growing debate about the role of rebirth in Buddhist ethics, Dale S. Wright has recently advocated distinguishing and distancing the concept of karma from that of rebirth. In this paper, I evaluate Wright’s arguments in the light of Immanuel Kant’s views about supernatural beliefs. Although Kant is a paradigmatic Enlightenment critic of metaphysical speculation and traditional dogmas, he also offers thought-provoking practical arguments in favor of adopting supernatural (theistic) beliefs. In the light of Kant’s views, I argue we (...) can assuage most of Wright’s worries about the traditional concept of rebirth and better identify the outstanding philosophic questions on which the debate between traditionalists and reformers rests. I conclude by expressing doubts about whether the karma controversy can be settled at a general level; I argue that it can be adequately discussed and resolved only within particular Buddhist traditions.

Summary of Nussbaum's book. Raises worries about the political neutrality of her psychoanalytic assumptions and about whether her compassion promoting policies can adequately mitigate problems like racism, selfishness, and partiality.

Although fairness is a key moral trait, limited research focuses on participants' observed fairness behavior because moral traits are generally measured through self-report. This experiment focused on day-to-day interpersonal fairness rather than impersonal justice, and fairness was assessed as observed behavior. The experiment investigated whether a self-reported fairness trait would moderate a situational influence on observed fairness behavior, such that individuals with a stronger fairness trait would be less affected by a situational influence than those with a weaker fairness trait. (...) We used an iterated resource game in which participants could withdraw resources as they chose, and we manipulated the number of resources bogus players withdrew. The number of resources participants withdrew was the behavioral measure of fairness. Results confirmed the expected moderation of the unfairness manipulation by a fairness trait on observed behavior. Those reporting a stronger fairness trait were unaffected by the manipulation, whereas those reporting a weaker fairness trait were more strongly influenced. (shrink)

As ever more advanced digital systems are created, it becomes increasingly likely that some of these systems will be digital minds, i.e. digital subjects of experience. With digital minds comes the risk of digital suffering. The problem of digital suffering is that of mitigating this risk. We argue that the problem of digital suffering is a high stakes moral problem and that formidable epistemic obstacles stand in the way of solving it. We then propose a strategy for solving it: Access (...) Monitor Prevent (AMP). AMP uses a ‘dancing qualia’ argument to link the functional states of certain digital systems to their experiences—this yields epistemic access to digital minds. With that access, we can prevent digital suffering by only creating advanced digital systems that we have such access to, monitoring their functional profiles, and preventing them from entering states with functional markers of suffering. After introducing and motivating AMP, we confront limitations it faces and identify some options for overcoming them. We argue that AMP fits especially well with—and so provides a moral reason to prioritize—one approach to creating such systems: whole brain emulation. We also contend that taking other paths to digital minds would be morally risky. (shrink)

Some physical theories predict that almost all brains in the universe are Boltzmann brains, i.e. short-lived disembodied brains that are accidentally assembled as a result of thermodynamic or quantum fluctuations. Physicists and philosophers of physics widely regard this proliferation as unacceptable, and so take its prediction as a basis for rejecting these theories. But the putatively unacceptable consequences of this prediction follow only given certain philosophical assumptions. This paper develops a strategy for shielding physical theorizing from the threat of Boltzmann (...) brains. The strategy appeals to a form of phenomenal externalism about the physical basis of consciousness. Given that form of phenomenal externalism, the proliferation of Boltzmann brains turns out to be benign. While the strategy faces a psychophysical fine-tuning problem, it both alleviates cosmological fine-tuning concerns that attend physics-based solutions to Boltzmann brain problems and pays explanatory dividends in connection with time’s arrow.

Our universe features a harmonious match between laws and states: applying its laws to its states generates other states. This is a striking fact. Matters might have been otherwise. The universe might have been stillborn in a state unengaged by its laws. The problem of nomological harmony is that of explaining the noted striking fact. After introducing and developing this problem, we canvass candidate solutions and identify some of their virtues and vices. Candidate solutions invoke the likes of a designer, (...) axiarchic meta-laws, multiverses, essential causal powers, and Humean laws. (shrink)

This article argues that we should be prudentially and morally biased toward earlier events: other things equal, we should prefer for good events to occur earlier and disprefer for bad events to occur earlier. The argument contends that we should accord at least some credence—if only a small one—to a theoretical package featuring the growing block theory of time and that that package generates a presumptive bias toward earlier events. Rival theoretical packages are considered. Under reasonable allocations of credence to (...) them, the presumptive bias escapes defeat. The argument has several corollaries: other things equal, we should be biased toward the past over the future, the further past over the nearer past, and the nearer future over the further future.

Uniqueness appears to enhance intrinsic value. A unique stamp sells for millions of dollars; Stradivarius violins are all the more precious because they are unlike any others. This observation has not gone overlooked in the value theory literature: uniqueness plays a starring role recalibrating the dominant Moorean understanding of the nature of intrinsic value. But the thesis that uniqueness enhances intrinsic value is in tension with another deeply plausible and widely held thesis, namely the thesis that there is a pro (...) tanto reason to promote the good. It is argued that there is a second, distinct type of uniqueness that plays a more interesting and important axiological role: uniqueness imparts irreplaceable value. This gives occasion to develop the surprisingly undertheorized notion of irreplaceable value. (shrink)

In Achievement, I suggest that failures can be just as good as achievements. Achievements are valuable because of their effort and competence, and some failures have these features too, and are therefore valuable for the same reasons. While that may be true, surely it’s also true that failures are, or can be, genuinely bad – not merely a privation of the good of achievement, but themselves intrinsically bad. As is the case for many bads, it is surprisingly difficult to give (...) an account that is not merely privative: viewed one way, a failure is simply a privation of attaining an end. This challenge is compounded by perfectionist theory of value, which may yield the most plausible account of achievement, but traditionally only offers an account of bads as privative. In this paper, I develop an account of failure as a robust bad by appealing to contrastive ends and the framework of tripartite perfectionism. (shrink)

Morality is intrapersonally permissive: cases abound in which an agent has more than one morally permitted option. In contrast, there is a dearth of cases in which an agent has more than one epistemically permitted response to her evidence. Given the structural parallels between morality and epistemology, why do sources of moral permissiveness fail to have parallel permissive effects in the epistemic domain? This asymmetry between morality and epistemology cries out for explanation. The paper's task is to offer an answer (...) to that call. We explain the asymmetry by tracing moral permissiveness to two factors to which rationality is morally but not epistemically sensitive. (shrink)

This is a presentation on Charles Sanders Peirce's pragmatic philosophy, and the ay that it functions in his conception of epistemology.

Andy Clark once remarked that we make the world smart so we don’t have to be (Clark, 1997). What he meant was that human beings (along with many other animals) alter and transform their environments in order to accomplish certain tasks that would prove difficult (or indeed impossible) without such transformations. This remarkable insight goes a long way towards explaining many aspects of human culture, ranging from linguistic notational systems to how we structure our cities. It also provides the basis (...) for Mark Rowlands’ thought-provoking and insightful book, The New Science of the Mind. (shrink)

Bradford Hill (1965) highlighted nine aspects of the complex evidential situation a medical researcher faces when determining whether a causal relation exists between a disease and various conditions associated with it. These aspects are widely cited in the literature on epidemiological inference as justifying an inference to a causal claim, but the epistemological basis of the Hill aspects is not understood. We offer an explanatory coherentist interpretation, explicated by Thagard's ECHO model of explanatory coherence. The ECHO model captures the (...) complexity of epidemiological inference and provides a tractable model for inferring disease causation. We apply this model to three cases: the inference of a causal connection between the Zika virus and birth defects, the classic inference that smoking causes cancer, and John Snow’s inference about the cause of cholera.

Gwen Bradford has plausibly argued that one attains achievement only if one does something one finds difficult. It is also plausible that one must attain achievement to be worthy of “agential” praise, praise that is appropriately directed to someone on the basis of things that redound to their credit. These claims pose a challenge to classical theists who direct agential praise to God, since classical theism arguably entails that none of God’s actions are difficult for God. I consider responses (...) to this challenge and commend a view accord- ing to which God’s loving character is not necessitated by God’s nature but is a contingent and difficult achievement. I argue that this view can still satisfy the explanatory ambitions of natural theology. (shrink)

The epidemiologist Bradford Hill famously argued that in epidemiology, specificity of association (roughly, the fact that an environmental or behavioral risk factor is associated with just one or at most a few medical outcomes) is strong evidence of causation. Prominent epidemiologists have dismissed Hill’s claim on the ground that it relies on a dubious `one-cause one effect’ model of disease causation. The paper examines this methodological controversy, and argues that specificity considerations do have a useful role to play in (...) causal inference in epidemiology. More precisely, I argue that specificity considerations help solve a pervasive inferential problem in contemporary epidemiology: the problem of determining whether an exposure-outcome correlation might be due to confounding by a social factor. This examination of specificity has interesting consequences for our understanding of the methodology of epidemiology. It highlights how the methodology of epidemiology relies on local tools designed to address specific inference problems peculiar to the discipline, and shows that observational causal inference in epidemiology can proceed with little prior knowledge of the causal structure of the phenomenon investigated. I also argue that specificity of association cannot (despite claims to the contrary) be entirely explained in terms of Woodward’s well-known concept of “one-to-one” causal specificity. This is because specificity as understood by epidemiologists depends on whether an exposure (or outcome) is associated with a `heterogeneous’ set of variables. This dimension of heterogeneity is not captured in Woodward’s notion, but is crucial for understanding the evidential import of specificity of association. (shrink)

An astonishing volume and diversity of evidence is available for many hypotheses in the biomedical and social sciences. Some of this evidence—usually from randomized controlled trials (RCTs)—is amalgamated by meta-analysis. Despite the ongoing debate regarding whether or not RCTs are the ‘gold-standard’ of evidence, it is usually meta-analysis which is considered the best source of evidence: meta-analysis is thought by many to be the platinum standard of evidence. However, I argue that meta-analysis falls far short of that standard. Different meta-analyses (...) of the same evidence can reach contradictory conclusions. Meta-analysis fails to provide objective grounds for intersubjective assessments of hypotheses because numerous decisions must be made when performing a meta-analysis which allow wide latitude for subjective idiosyncrasies to influence its outcome. I end by suggesting that an older tradition of evidence in medicine—the plurality of reasoning strategies appealed to by the epidemiologist Sir Bradford Hill—is a superior strategy for assessing a large volume and diversity of evidence.

There are many putative counterexamples to the view that all scientific explanations are causal explanations. Using a new theory of what it is to be a causal explanation, Bradford Skow has recently argued that several of the putative counterexamples fail to be non-causal. This paper defends some of the counterexamples by showing how Skow’s argument relies on an overly permissive theory of causal explanations.

This paper examines perfectionist attempts to explain the prudential badness of pain (its badness for those who experience it). It starts by considering simple perfectionist explanations, finding them wanting, before considering the most sophisticated perfectionist attempt to explain prudential badness: Gwen Bradford’s tripartite perfectionism. The paper argues that Bradford’s view, though an improvement on earlier perfectionist proposals, still does not satisfactorily explain the full set of prudentially bad pains. It ends by showing how this provides grounds for a (...) general kind of pessimism about perfectionism and the badness of pain and how this case undermines a general purported advantage of perfectionism over the objective list theory.

The most cursory examination of the history of artificial intelligence highlights numerous egregious claims of its researchers, especially in relation to a populist form of ‘strong’ computationalism which holds that any suitably programmed computer instantiates genuine conscious mental states purely in virtue of carrying out a specific series of computations. The argument presented herein is a simple development of that originally presented in Putnam’s (Representation & Reality, Bradford Books, Cambridge in 1988 ) monograph, “Representation & Reality”, which if correct, (...) has important implications for turing machine functionalism and the prospect of ‘conscious’ machines. In the paper, instead of seeking to develop Putnam’s claim that, “everything implements every finite state automata”, I will try to establish the weaker result that, “everything implements the specific machine Q on a particular input set ( x )”. Then, equating Q ( x ) to any putative AI program, I will show that conceding the ‘strong AI’ thesis for Q (crediting it with mental states and consciousness) opens the door to a vicious form of panpsychism whereby all open systems, (e.g. grass, rocks etc.), must instantiate conscious experience and hence that disembodied minds lurk everywhere.

This paper is a contribution to a book symposium on my book Experiencing Time. I reply to comments on the book by Natalja Deng, Geoffrey Lee and Bradford Skow. Although several chapters of the book are discussed, the main focus of my reply is on Chapters 2 and 6. In Chapter 2 I argue that the putative mind-independent passage of time could not be experienced, and from this I develop an argument against the A-theory of time. In Chapter 6 (...) I offer one part of an explanation of why we are disposed to think that time passes, relating to the supposedly ‘dynamic’ quality of experienced change. Deng, Lee, and Skow’s comments help me to clarify several issues, add some new thoughts, and make a new distinction that was needed, and I acknowledge, as I did in the book, that certain arguments in Chapter 6 are not conclusive; but I otherwise concede very little regarding the main claims and arguments defended in the book.

This paper critically assesses existing accounts of the nature of difficulty, finds them wanting, and proposes a new account. The concept of difficulty is routinely invoked in debates regarding degrees of moral responsibility, and the value of achievement. Until recently, however, there has not been any sustained attempt to provide an account of the nature of difficulty itself. This has changed with Gwen Bradford’s Achievement, which argues that difficulty is a matter of how much intense effort is expended. But (...) while this account captures something important about the relationship between difficulty and achievement, it fails to account for the fact that part of what makes achievements great is that they are difficult in a moderately agent-neutral kind of way. Nor is this thought captured by any other extant account. I argue that to fill this gap we should think of difficulty in terms of low probability of success. (shrink)

The Harvard physiologists Alexander Forbes (1882-1965) and Walter Bradford Cannon (1871-1945) had an enormous impact on the physiology and neuroscience of the twentieth century. In addition to their voluminous scientific output, they also used literature to reflect on the nature of science itself and its social significance. Forbes wrote a novel, The Radio Gunner, a literary memoir, Quest for a Northern Air Route, and several short stories. Cannon, in addition to several books of popular science, wrote a literary memoir (...) in the last year of his life, The Way of an Investigator. The following will provide a brief overview of the life and work of Forbes and Cannon. It will then discuss the way that Forbes used literature to express his views about the changing role of communications technology in the military, and his evolving view of the nervous system itself as a kind of information-processing device. It will go on to discuss the way that Cannon used literature to articulate the horrors he witnessed on the battlefield, as well as to contribute to the philosophy of science, and in particular, to the logic of scientific discovery. Finally, it will consider the historical and philosophical value of deeper investigation of the literary productions of scientists. (shrink)

Recently, companions in guilt strategies have garnered significant philosophical attention as a response to arguments for moral error theory, the view that there are no moral facts and that our moral beliefs are thus systematically mistaken. According to Cuneo (The normative web: an argument for moral realism, Oxford University Press, Oxford, 2007), Das (Philos Q 66:152–160, 2016; Australas J Philos 95(1):58–69, 2017), Rowland (J Ethics Soc Philos 7(1):1–24, 2012; Philos Q 66:161–171, 2016) and others, epistemic facts would be just as (...) metaphysically problematic (or ‘guilty’) as moral facts. But since epistemic error theory is implausible, arguments for moral error theory prove too much and should be rejected. My aim is to argue that the success of this strategy is limited. In particular, the companions in guilt response fails against error-theoretic arguments motivated by concerns about explanatory dispensability, as recently developed by Joyce (The evolution of morality, MIT press, Bradford, 2005) and Olson (Moral error theory: history, critique, defence, Oxford University Press, Oxford, 2014: Ch. 7). To succeed, the response would require a prima facie plausible argument to the effect that epistemic facts are metaphysically dubious because they, too, are explanatorily dispensable. But, as I show, any such argument proves self-effacing: its premise commits us to believing in epistemic facts, while its conclusion forces us to deny their existence. Consequently, companions in guilt strategies don’t offer a panacea against arguments for moral error theory. (shrink)

Quine (1960, "Word and object". Cambridge, Mass.: MIT Press, ch. 2) claims that there are a variety of equally good schemes for translating or interpreting ordinary talk. 'Rabbit' might be taken to divide its reference over rabbits, over temporal slices of rabbits, or undetached parts of rabbits, without significantly affecting which sentences get classified as true and which as false. This is the basis of his famous 'argument from below' to the conclusion that there can be no fact of the (...) matter as to how reference is to be divided. Putative counterexamples to Quine's claim have been put forward in the past (see especially Evans (1975, "Journal of Philosophy", LXXII(13), 343-362. Reprinted in McDowell (Ed.), "Gareth Evans: Collected papers." Oxford: Clarendon Press.), Fodor (1993, "The elm and the expert: Mentalese and its semantics." Cambridge, MA: Bradford)), and various patches have been suggested (e. g. Wright (1997, The indeterminacy of translation. In C. Wright & B. Hale (Eds.), "A companion to the philosophy of language" (pp. 397-426). Oxford: Blackwell)). One lacuna in this literature is that one does not find any detailed presentation of what exactly these interpretations are supposed to be. Drawing on contemporary literature on persistence, the present paper sets out detailed semantic treatments for fragments of English, whereby predicates such as 'rabbit' divide their reference over four-dimensional continuants (Quine's rabbits), instantaneous temporal slices of those continuants (Quine's rabbitslices) and the simple elements which compose those slices (undetached rabbit parts) respectively. Once we have the systematic interpretations on the table, we can get to work evaluating them. (shrink)

I bought this thinking anything from Bradford books and MIT must be good. Instead it's a boring, stupid, incompetent, antiscientific and antirational piece of closet creationist trash. Heads should roll at Bradford for this atrocity! If you must then start by reading the last chapter first as he conceals a frank statement of his anti-rationality til the end. I made detailed notes on it as I thought it was a serious work of science and was going to do (...) a long page by page refutation but why bother! The praise from some Science and Nature reviewers shows they did not read it and/or have as little understanding of behavior as Buller. The positive comments from the jacket by Sterelny, Wilson, Sober and Caporael are due to the fact that they all share Buller's retro antirational blank slate views that human nature is due to our culture and the delusion of group selection (see my review of Wilson's The Social Conquest of Earth). The first part of the book is dull repeats of basic biology cribbed from intro texts and unrelieved by photos or drawings. Along the way there are some incredibly bizarre takes on the use of language and scientific method. Then you find an attempt to refute some well known studies of stepchild abuse. As you get to the end he lets his anti-science and anti-rationality out in the open, telling us that regardless of whether our behavior is innate we should not investigate it! The fact that our brain is no different from our other organs and it's functions a product of genes and evolution continues to be resisted or just ignored not only by academics but by the general public. Nevertheless the basics of our behavior are as innate as our heartbeat and detailed evidence (for those who have trouble with the obvious) is all around us everywhere we look once our eyes are opened-just watch people doing anything or turn on the tv (or see the huge and rapidly growing scientific literature). Novices can start with Pinker's "The Blank Slate" but there are now dozens of good popular and scientific books on evolutionary psychology and hundreds of articles in the literature of philosophy, psychology, economics etc. The articles in Buss's The Handbook of Evolutionary Psychology and some at the end of Gazzinaga's The Cognitive Neurosciences 3 are good starting points for the serious reader., and science are all manifestations of our innate psychology (with the minor extensions we call culture and civilization), you can look almost anywhere in literature or life to study our adapted mind except here. -/- Those wishing a comprehensive up to date framework for human behavior from the modern two systems view may consult my book ‘The Logical Structure of Philosophy, Psychology, Mind and Language in Ludwig Wittgenstein and John Searle’ 2nd ed (2019).
