Decision theory has had a long-standing history in the behavioural and social sciences as a tool for constructing good approximations of human behaviour. Yet as artificially intelligent systems (AIs) grow in intellectual capacity and eventually outpace humans, decision theory becomes evermore important as a model of AI behaviour. What sort of decision procedure might an AI employ? In this work, I propose that policy-based causal decision theory (PCDT), which places a primacy on the decision-relevance of predictors and simulations of agent (...) behaviour, may be such a procedure. I compare this account to the recently-developed functional decision theory (FDT), which is motivated by similar concerns. I also address potentially counterintuitive features of PCDT, such as its refusal to condition on observations made at certain times. (shrink)

This book is a collection of eleven essays by one of the most interesting moral philosophers currently writing. It examines challenges to liberal thought posed by the changing circumstances of the modern world such as the conflicting tendencies toward global integration, and greater ethnic and communal identification. The author considers whether liberal principles of justice can accommodate social and global interdependencies while reaffirming the importance of individual responsibility and acknowledging the significance of people's diverse personal and communal allegiances.

This paper addresses the extent to which both Julian Barbour‘s Machian formulation of general relativity and his interpretation of canonical quantum gravity can be called timeless. We differentiate two types of timelessness in Barbour‘s (1994a, 1994b and 1999c). We argue that Barbour‘s metaphysical contention that ours is a timeless world is crucially lacking an account of the essential features of time—an account of what features our world would need to have if it were to count as being one in which (...) there is time. We attempt to provide such an account through considerations of both the representation of time in physical theory and in orthodox metaphysical analyses. We subsequently argue that Barbour‘s claim of timelessness is dubious with respect to his Machian formulation of general relativity but warranted with respect to his interpretation of canonical quantum gravity. We conclude by discussing the extent to which we should be concerned by the implications of Barbour‘s view. (shrink)

The threat of bioterrorism, the emergence of the SARS epidemic, and a recent focus on professionalism among physicians, present a timely opportunity for a review of, and renewed commitment to, physician obligations to care for patients during epidemics. The professional obligation to care for contagious patients is part of a larger "duty to treat," which historically became accepted when 1) a risk of nosocomial infection was perceived, 2) an organized professional body existed to promote the duty, and 3) the public (...) came to rely on the duty. Physicians' responses to epidemics from the Hippocratic era to the present suggests an evolving acceptance of the professional duty to treat contagious patients, reaching a long-held peak between 1847 and the1950's. There has been some professional retrenchment against this duty to treat in the last 40 years but, we argue, conditions favoring acceptance of the duty are met today. A renewed embrace of physicians' duty to treat patients during epidemics, despite conditions of personal risk, might strengthen medicine's relationship with society, improve society's capacity to prepare for threats such as bioterrorism and new epidemics, and contribute to the development of a more robust and meaningful medical professionalism.

If the force on a particle fails to satisfy a Lipschitz condition at a point, it relaxes one of the conditions necessary for a locally unique solution to the particle’s equation of motion. I examine the most discussed example of this failure of determinism in classical mechanics—that of Norton’s dome—and the range of current objections against it. Finding there are many different conceptions of classical mechanics appropriate and useful for different purposes, I argue that no single conception is preferred. Instead (...) of arguing for or against determinism, I stress the wide variety of pragmatic considerations that, in a specific context, may lead one usefully and legitimately to adopt one conception over another in which determinism may or may not hold.

I argue that Spinoza endorses "conceptual dependence monism," the thesis that all forms of metaphysical dependence (such as causation, inherence, and existential dependence) are conceptual in kind. In the course of explaining the view, I further argue that it is actually presupposed in the proof for his more famed substance monism. Conceptual dependence monism also illuminates several of Spinoza’s most striking metaphysical views, including the intensionality of causal contexts, parallelism, metaphysical perfection, and explanatory rationalism. I also argue that this priority (...) of the conceptual does not commit Spinoza to forms of idealism or mentalism. The question of how to understand different kinds of metaphysical dependence is quite controversial in Spinoza studies; I address major alternative readings in the notes. But there I also try to draw connections to the growing debate in contemporary discussions about metaphysical dependence, as this topic is a happy point of shared interest between Spinoza and contemporary metaphysicians alike.

We consider two reasons why firms should be owned and run democratically by their workers. The first concerns accountability : Because the employment relationship involves the exercise of power, its governance should on democratic grounds be accountable to those most directly affected. The second concerns efficiency : The democratic firm uses a lower level of inputs per unit of output than the analogous capitalist firm.

Events and event prediction are pivotal concepts across much of cognitive science, as demonstrated by the papers in this special issue. We first discuss how the study of events and the predictive processing framework may fruitfully inform each other. We then briefly point to some links to broader philosophical questions about events.

This paper proposes a refocusing of consent for clinical genetic testing, moving away from an emphasis on autonomy and information provision, towards an emphasis on the virtues of healthcare professionals seeking consent, and the relationships they construct with their patients. We draw on focus groups with UK healthcare professionals working in the field of clinical genetics, as well as in-depth interviews with patients who have sought genetic testing in the UK’s National Health Service. We explore two aspects of consent: first, (...) how healthcare professionals consider the act of ‘consenting’ patients; and second how these professional accounts, along with the accounts of patients, deepen our understanding of the consent process. Our findings suggest that while healthcare professionals working in genetic medicine put much effort into ensuring patients’ understanding about their impending genetic test, they acknowledge, and we show, that patients can still leave genetic consultations relatively uninformed. Moreover, we show how placing emphasis on the informational aspect of genetic testing is not always reflective of, or valuable to, patients’ decision-making. Rather, decision-making is socially contextualised – also based on factors outside of information provision. A more collaborative on-going consent process, grounded in virtue ethics and values of honesty, openness and trustworthiness, is proposed. (shrink)

According to the attentional resources account, mind wandering (or “task-unrelated thought”) is thought to compete with a focal task for attentional resources. Here, we tested two key predictions of this account: First, that mind wandering should not interfere with performance on a task that does not require attentional resources; second, that as task requirements become automatized, performance should improve and depth of mind wandering should increase. Here, we used a serial reaction time task with implicit- and explicit-learning groups to test (...) these predictions. Providing novel evidence for the attentional resource account’s first prediction, results indicated that depth of mind wandering was negatively associated with learning in the explicit, but not the implicit, group, indicating that mind wandering is associated with impaired explicit, but not implicit, learning. Corroborating the attention resource account’s second prediction, we also found that, overall, performance improved while at the same time depth of mind wandering increased. From an implicit learning perspective, these results are consistent with the claim that explicit learning is impaired under attentional load, but implicit learning is not. (shrink)

Recently there has been a growing literature on the concept of moral certainty. This concept, which is inspired by Wittgenstein’s reflections in On Certainty, is most prominently argued for by Nigel Pleasants. Pleasants contends that there is a meaningful parallel to be drawn between the epistemic certainties discussed by Wittgenstein and moral certainties. These moral certainties are unreflective, non-propositional, and show in the ways that we act. In addition, these certainties cannot be doubted by a reasonable moral agent. In a (...) recently published article, Fairhurst is critical of Pleasants’ account. Fairhurst argues that there are problems with Pleasants’ example of a moral certainty, 'it is wrong to kill innocent non-threatening people'. Fairhurst appeals to euthanasia as an example of when a reasonable person could meaningfully doubt that it is wrong to kill innocent, non-threatening people. If this is a certainty, then a doubt such as this should not be possible. In addition, he argues that Pleasants’ claim that moral certainties are natural is not well substantiated. In this article, I attempt to defend an account of moral certainty against Fairhurst’s criticisms. I divide his criticisms into two parts. His first set of criticisms deal with Pleasants’ example of a moral certainty. I argue that some of his criticisms are inconsistent while others can be addressed by making a small amendment to Pleasants’ account. His second criticism deals with Pleasants’ claim that moral certainties are natural. In order to address this criticism, I appeal to Machery’s Nomological Account of human nature and use it as a basis that allows us to consistently make the claim that there are natural moral certainties.

The four authors present their speculations about the future developments of mathematical logic in the twenty-first century. The areas of recursion theory, proof theory and logic for computer science, model theory, and set theory are discussed independently.

Understanding inductive reasoning is a problem that has engaged mankind for thousands of years. This problem is relevant to a wide range of fields and is integral to the philosophy of science. It has been tackled by many great minds ranging from philosophers to scientists to mathematicians, and more recently computer scientists. In this article we argue the case for Solomonoff Induction, a formal inductive framework which combines algorithmic information theory with the Bayesian framework. Although it achieves excellent theoretical results (...) and is based on solid philosophical foundations, the requisite technical knowledge necessary for understanding this framework has caused it to remain largely unknown and unappreciated in the wider scientific community. The main contribution of this article is to convey Solomonoff induction and its related concepts in a generally accessible form with the aim of bridging this current technical gap. In the process we examine the major historical contributions that have led to the formulation of Solomonoff Induction as well as criticisms of Solomonoff and induction in general. In particular we examine how Solomonoff induction addresses many issues that have plagued other inductive systems, such as the black ravens paradox and the confirmation problem, and compare this approach with other recent approaches.

Sledging, or ‘trash talk’ or ‘chirping’, as it’s known in other parts of the world, has long been part of competitive sport. However, more recent times have seen the issue of sledging, and its place in sport, debated with many athletes, fans and academics arguing that sledging has moved outside the notion of ‘sportsmanship’ and gone beyond light hearted, good natured banter. They argue it is now characterized as hurtful, insulting, offensive and intimidating – a tactic that has moved beyond (...) fair play and, in many instances, no longer acceptable. This paper seeks to explore this issue in greater depth. In particular, this paper seeks to ask, ‘is sledging part of play, or is it a characteristic of play’s corruption?’ The argument proceeds by adopting a conception of play grounded in the work of Johan Huizinga. Play may be understood as a core component of even professional sport, not least in that play lies at the moral core of the ‘spirit of sport’ in fairplay and respect for one’s opponents. Using...

The role or function of experimental and observational replication within empirical science has implications for how replication should be measured. Broadly, there seems to be consensus that replication’s central goal is to confirm or vouchsafe the reliability of scientific findings. I argue that if this consensus is correct, then most of the measures of replication used in the scientific literature are actually poor indicators of this reliability or confirmation. Only meta-analytic measures of replication align functionally with the goals of replication. (...) I conclude by addressing some objections to meta-analysis. (shrink)

This paper will develop the concept of semiogenesis – a process of novel sign generation – and how instances of this process, such as agency, relate to their built environment and beyond. Section two will build on Hoffmeyer’s discussion of swarms, specifically the idea of overlapping swarms and its manifestation in the creation of termite mounds, in order to introduce three types of structure. Building upon this real-world example explored in section two, the third section will present a heuristic for (...) semiogenesis: a neuromorphic dynamic system model grounded in information and thermodynamic theory. Through the lens of this heuristic model, the penultimate section will more rigorously characterize the similarities and differences between termite and human agency in their respective built milieus.

We began with the observation that language is often held to enact the world. We have examined several instances of this notion, beginning with a discussion of the folk etymology of certain words, moving through an example of Freud, to Morgenstern, Lettvin, and Stevens. The method shared by these examples assumes that words are literally saturated with meaning; that what appears arbitrary or senseless in them can be made to render up its sense and its motivation through a kind of (...) inspired analysis. Our intent has been to show how this principle of folk etymology lies behind some sophisticated creative thinking. In Freud, it is hypothesized to be a psychological mechanism of some depth. In Morgenstern and Lettvin, it forms the basis for a resonant poetic joke, while in Stevens it appears to have the same major status as the mythic principle of creation-through-language illustrated in our first examples from Egyptian mythology and from Genesis. Stevens, of course, uses the principle to create poetry, not religion; for as he says in section 5 of "The Man with the Blue Guitar": Poetry Exceeding music must take the placeOf empty heaven and its hymns . . . Samuel Jay Keyser, head of the department of linguistics and philosophy at the Massachusetts Institute of Technology and editor of Linguistic Inquiry, is the coauthor of English Stress: Its Form, Its Growth and Its Role in Verse and of Beginning English Grammar. Alan Prince, an assistant professor of linguistics at the University of Massachusetts at Amherst, has written on stress and linguistic rhythm and is currently working, with Keyser, on the poetry of Wallace Stevens.

Like process theism, Christian theology affirms the immanence of God in the world and of the world in God. Unlike process theism, it also affirms the ontological priority of God over the world. As a result, Christian theologians will object to describing God’s relation to the world by analogy with the mind’s relation to the body or in terms of whole-part relations. In Christian history, the God-world relation has been more often described in terms of “participation.” The world is said (...) to participate in God, keeping in mind that this language is highly metaphorical. The idea of participation is a development of themes enunciated by Plato and Aristotle, but adapted by Christian theologians to trinitarian ends. The created world participates in God by reflecting the trinitarian life of identity and difference. This establishes an organic and internal relation between God and the world. (shrink)

The central subject of Aristotle's ethics is happiness or living well. Most people in his day (as in ours), eager to enjoy life, impressed by worldly success, and fearful of serious loss, believed that happiness depends mainly on fortune in achieving prosperity and avoiding adversity. Aristotle, however, argues that virtuous conduct is the governing factor in living well and attaining happiness. While admitting that neither the blessings not the afflictions of fortune are unimportant, he maintains that the virtuous find life (...) more satisfying than other people do and, with only modest good fortune, they lead happy, enjoyable lives. Combining philological precision with philosophical analysis, the author reconstructs Aristotle's defense of these bold claims. By examining how Aristotle develops his position in response to the prevailing hopes and anxieties of his age, the author shows why Aristotle considers happiness important for ethics and why he thinks it necessary to revise popular and traditional views. Paying close attention throughout to the internalist dimension of Aristotle's approach - his emphasis on how the virtuous view their own lives and actions - the author advances new interpretations of Aristotle's accounts of several major virtues, including temperance, courage, liberality, and 'greatness of soul'. This work sets Aristotle in the broader cultural context of his time, tracing his attemps to accommodate and amend rival views. The author examines literary and historical sources as well as philosophical texts, showing the inherited values and traditional ideals that inform Aristotle's discussions and provide some of the basis for his conclusions. Presupposing no knowledge of Greek or specialized philosophical terminology, the book is designed to be accessible to all students of philosophy or classical antiquity. All quotations from ancient texts are translated. (shrink)

Noncognitivism about normative judgment is the view that normative judgment is a distinctive kind of mental state, identical neither to belief or desire, but desire-like in its functional role and direction of fit. Noncognitivism about intention (also called the “distinctive practical attitude” theory) is the view that intention is a distinctive kind of mental state, identical neither to belief or desire, but desire-like in its functional role and direction of fit. While these theories are alike in several ways, they have (...) rarely been discussed in concert. This paper studies the relation between these two theories, focusing on the question of whether noncognitivism about intention faces an analogue of the well-known Frege-Geach problem for noncognitivism about normative judgment. I argue that whether it faces the Frege-Geach problem depends on how it treats the distinction between what Anscombe called expressions of intention and personal predictions. I show that there is substantial pressure to treat that distinction as semantic, and that a variant of the Frege-Geach problem arises for versions of noncognitivism about intention that go this route. Yet some philosophers of action may be willing to resist this pressure, and I develop a pragmatic account of the distinction that would allow such philosophers to avoid the Frege-Geach problem altogether. I argue that this pragmatic account has significant independent appeal. Notably, it provides a way for noncognitivists about intention to undercut the force of a recent argument for cognitivism due to Berislav Marušić and John Schwenkler. (shrink)

For the last fifty years, the United States healthcare system has done an extremely poor job of delivering healthcare in a just and fair manner. The United States holds the dubious distinction of being the only industrialized nation in the world lacking provisions to ensure universal coverage. We attempt to provide some of the reasons this dysfunctional system has persisted and show that healthcare should not be a commodity. We begin with a brief historical overview of healthcare delivery in the (...) United States since WWII. This is followed by a critical analysis of the for-profit model including reasons to support the view that healthcare should not be a free market commodity. We also demonstrate how special interest groups have been able to win support for their practices based on propaganda rather than fact. A brief analysis of the Affordable Care Act is offered along with critical comments regarding its ineffectiveness. We conclude with a brief overview of international approaches that have resulted in universal coverage and suggest the United States ought to adopt an approach similar to those outlined so that it no longer stands as the only industrialized nation to ignore the glaring problems that exist.

Peirce's Reality and Berkeley's Blunders LESLEY FRIEDMAN IN A NUMBER OF HIS LATE REMARKS, Peirce makes it clear that he holds Bishop Berkeley in the highest esteem. Hailed as the "father of all modern philoso- phy," Peirce argues that Berkeley, not Kant, "first produced an Erkenntnis- theorie, or 'principles of human knowledge', which was for the most part cor- rect in its positive assertions" ? This is not at all to say that Berkeley escapes rebuke; in spite of several laudatory (...) remarks, ~ Peirce takes him to task for two errors: his view of reality as actual perception, and his neglect of real possibility. Additionally, in some passages we find Berkeley both credited for some insight and admonished for some oversight.

Using psychosocial acceleration theory, this multimethod, multi-reporter study examines how early adversity adaptively shapes the development of a self-regulation construct: effortful control. Investigation of links between early life harshness and unpredictability and the development of effortful control could facilitate a nuanced understanding of early environmental effects on cognitive and social development. Using the Building Strong Families national longitudinal data set, aspects of early environmental harshness and early environmental unpredictability were tested as unique predictors of effortful control at age 3 using (...) multiple regression. Early harshness variables were financial harshness, mothers’ and fathers’ observed parenting, mothers’ and fathers’ reported use of harsh discipline, and harsh neighborhood conditions. Early unpredictability was measured by number of paternal transitions. Cues of harshness, specifically observed unresponsive parenting, observed harsh parenting, and neighborhood harshness, did significantly negatively predict effortful control. Paternal transitions also significantly predicted effortful control, but in the opposite (i.e., positive) direction. The results corroborate previous research linking quality of parenting to the development of children’s effortful control and place it within an evolutionary-developmental theoretical framework. Further, the results suggest that neighborhood harshness may also direct developmental trajectories of effortful control in young children, though the mechanisms through which this occurs are still unclear. This is the first study to explicitly investigate effortful control development in early childhood within the harshness and unpredictability framework. (shrink)
