Scientific models describe natural phenomena at different levels of abstraction. Abstract descriptions can provide the basis for interventions on the system and explanation of observed phenomena at a level of granularity that is coarser than the most fundamental account of the system. Beckers and Halpern (2019), building on work of Rubenstein et al. (2017), developed an account of abstraction for causal models that is exact. Here we extend this account to the more realistic case where an abstract causal model offers (...) only an approximation of the underlying system. We show how the resulting account handles the discrepancy that can arise between low- and high-level causal models of the same system, and in the process provide an account of how one causal model approximates another, a topic of independent interest. Finally, we extend the account of approximate abstractions to probabilistic causal models, indicating how and where uncertainty can enter into an approximate abstraction. (shrink)

Causal models have proven extremely useful in offering formal representations of causal relationships between a set of variables. Yet in many situations, there are non-causal relationships among variables. For example, we may want variables LDL, HDL, and TOT that represent the level of low-density lipoprotein cholesterol, the level of lipoprotein high-density lipoprotein cholesterol, and total cholesterol level, with the relation LDL+HDL=TOT. This cannot be done in standard causal models, because we can intervene simultaneously on all three variables. The goal of (...) this paper is to extend standard causal models to allow for constraints on settings of variables. Although the extension is relatively straightforward, to make it useful we have to define a new intervention operation that disconnects a variable from a causal equation. We give examples showing the usefulness of this extension, and provide a sound and complete axiomatization for causal models with constraints. (shrink)

As autonomous systems rapidly become ubiquitous, there is a growing need for a legal and regulatory framework to address when and how such a system harms someone. There have been several attempts within the philosophy literature to define harm, but none of them has proven capable of dealing with with the many examples that have been presented, leading some to suggest that the notion of harm should be abandoned and "replaced by more well-behaved notions". As harm is generally something that (...) is caused, most of these definitions have involved causality at some level. Yet surprisingly, none of them makes use of causal models and the definitions of actual causality that they can express. In this paper we formally define a qualitative notion of harm that uses causal models and is based on a well-known definition of actual causality (Halpern, 2016). The key novelty of our definition is that it is based on contrastive causation and uses a default utility to which the utility of actual outcomes is compared. We show that our definition is able to handle the examples from the literature, and illustrate its importance for reasoning about situations involving autonomous systems. (shrink)

We consider a sequence of successively more restrictive definitions of abstraction for causal models, starting with a notion introduced by Rubenstein et al. (2017) called exact transformation that applies to probabilistic causal models, moving to a notion of uniform transformation that applies to deterministic causal models and does not allow differences to be hidden by the "right" choice of distribution, and then to abstraction, where the interventions of interest are determined by the map from low-level states to high-level states, and (...) strong abstraction, which takes more seriously all potential interventions in a model, not just the allowed interventions. We show that procedures for combining micro-variables into macro-variables are instances of our notion of strong abstraction, as are all the examples considered by Rubenstein et al. (shrink)

It is argued that Nuyen's objectivist perspective on the method of the natural sciences is misleading, failing to capture its primary feature: maintaining a separation between two levels--a level takes as observations and data and a level taken as conceptually integrated theory--and at the same time working between these two levels in a manner that draws them together. Appropriately articulated this feature gives a perspective that (i) sees in the natural sciences an essential relation between knower and known similar to (...) that attributed by Nuyen to the human sciences; and (ii) specifies the function of generalization in the natural sciences in a manner that specifies crucial questions challenging Nuyen's contrast of the natural and human sciences.

Anti-luck epistemology is an approach to analyzing knowledge that takes as a starting point the widely-held assumption that knowledge must exclude luck. Call this the anti-luck platitude. As Duncan Pritchard (2005) has suggested, there are three stages constituent of anti-luck epistemology, each which specifies a different philosophical requirement: these stages call for us to first give an account of luck; second, specify the sense in which knowledge is incompatible with luck; and finally, show what conditions must be satisfied in order (...) to block the kind of luck with which knowledge was argued to be incompatible. What I’ll show here is that the modal account of luck offers a plausible story at the first stage and leads naturally to equally plausible lines to take at the second and third stages, at which a safety condition on knowledge is squarely motivated. There are, however, recent challenges—advanced by Jonathan Kvanvig (Philosophy and Phenomenological Research 77: 272–281, 2008); Kelly Becker (2007); and Jennifer Lackey (Australasian Journal of Philosophy 86(2):255–267, 2008), among others—to the plausibility of the safety-based anti-luck project I’ve sketched here at each of its three stages of development. Once I’ve made precise the challenges, I’ll show why none implies that we abandon the commitments of the safety-based anti-luck project at any of its stages. What we should conclude, then, is that a safety-condition on knowledge is motivated by independently defensible accounts of (1) what luck is; and (2) just how knowledge should be thought incompatible with it.

José Benardete developed a famous paradox involving a beginningless set of items each member of which satisfies some predicate just in case no earlier member satisfies it. The Grim Reaper version of this paradox has recently been employed in favor of various finitist metaphysical theses, ranging from temporal finitism to causal finitism to the discrete nature of time. Here, I examine a new challenge to these finitist arguments—namely, the challenge of implying that the future cannot be endless. In particular, I (...) develop future-oriented Benardete paradoxes and examine their epistemic symmetry with past-oriented paradoxes. (shrink)

As scholars envision a new regulatory or statutory neurorights schema it is important to imagine unintended consequences if reforms are implemented before their implications are fully understood. This paper critically evaluates provisions proposed for a new Chilean Constitution and evaluates this movement against efforts to improve the diagnosis of, and treatment for, individuals with disorders of consciousness within the broader context of disability law, international human rights, and a capabilities approach to health justice as advanced by Amartya Sen and Martha (...) Nussbaum. Framed in this way, any neurorights regime would need to satisfy several criteria. First it would be obliged to balance both positive and negative rights in the furtherance of human capabilities. Second, it would need to be future oriented and informed about the science it sought to regulate and not fall prey to science fiction fantasies that remain ungrounded in reality. Third, it would need to be specific and avoid generalizations that would lead to conceptual confusion and litigation that could delay scientific progress. Finally, it would need to harmonize novel neurorights with long-established norms in international disability and human rights law. A failure to meet these criteria will destine any novel neurorights regime to the periphery. At this juncture Chile’s nascent constitutional venture into neurorights fails to satisfy these criteria. While there yet may be a role for a more capacious and bivalent articulation of neurorights that account for capabilities and precedent, the current Chilean neurorights reforms are vague and premature. As such they should undergo additional scholarly scrutiny and should not be adopted by other jurisdictions. (shrink)

The idea that payment for research participation can be coercive appears widespread among research ethics committee members, researchers, and regulatory bodies. Yet analysis of the concept of coercion by philosophers and bioethicists has mostly concluded that payment does not coerce, because coercion necessarily involves threats, not offers. In this article we aim to resolve this disagreement by distinguishing between two distinct but overlapping concepts of coercion. Consent-undermining coercion marks out certain actions as impermissible and certain agreements as unenforceable. By contrast, (...) coercion as subjection indicates a way in which someone’s interests can be partially set back in virtue of being subject to another’s foreign will. While offers of payment do not normally constitute consent-undermining coercion, they do sometimes constitute coercion as subjection. We offer an analysis of coercion as subjection and propose three possible practical responses to worries about the coerciveness of payment. (shrink)

This is the first article in a two-part series describing subject and family perspectives from the central thalamic deep brain stimulation for the treatment of traumatic brain injury using the Medtronic PC + S first-in-human invasive neurological device trial to achieve cognitive restoration in moderate to severe traumatic brain injury, with subjects who were deemed capable of providing voluntary informed consent. In this article, we report on interviews conducted prior to surgery wherein we asked participants about their experiences recovering from (...) brain injury and their perspectives on study enrollment and participation. We asked how risks and benefits were weighed, what their expectations and fears were, and how decisions were reached about trial participation. We found that informed consent and enrollment decisions are fraught. Subjects and families were often split, with subjects more focused on putative benefits and families concerned about incremental risk. Both subjects and families viewed brain injury as disruptive to personal identity and relationships. As decisions were made about study enrollment, families struggled with recognizing the re-emergent agency of subjects and ceding decision-making authority to subjects who had previously been dependent upon them for protection and guidance. Subjects and family members reported a hope for the relief of cognitive disabilities, improved quality of life, normalization of interpersonal interactions, and a return to work or school as reasons for study participation, along with altruism and a desire to advance science. Despite these aspirations, both subjects and families appreciated the risks of the intervention and did not suffer from a therapeutic misconception. A second essay to be published in the next issue of Cambridge Quarterly of Healthcare Ethics—Clinical Neuroethics will describe interviews conducted after surgery, the effects of cognitive restoration for subjects, families, and challenges presented to the social structures they will call upon to support them through recovery. This subsequent article will be available online prior to its formal publication in October 2023. (shrink)

The transcendental expectation of string theory is that the nature of the fundamental forces, particle spectra and masses, together with coupling constants, is uniquely determined by mathematical and logical consistency, non-empirically, that is by pure reason. However pluralism triumphed with the explosive emergence of the multiverse. String theorists have extended a long-sought dream to a landscape or a happy caparnaum. Proponents of string theory try to qualify their arguments via swampland conjectures while cosmologists retreat to their telescopes. We review the (...) current status of the string theory swampland.

That Descartes’ God is not a deceiver is amongst the canonical claims of early modern philosophy. The significance of this (purported) fact to the coherence of Descartes’ system is likewise canonical, infused in how we teach and think about the _Meditations_. Though prevalent, both ends of this narrative are suspect. We argue that Descartes’ color eliminativism, when coupled with his analysis of the cognitive structure of our sensory systems, entails that God is a deceiver. It’s doubtful that Descartes recognized this, (...) given his insistence that God is not a deceiver, and the role this plays in his system. But this is a concession Descartes can grant if we are careful about the kind of deception at play—a kind Descartes _does_ recognize, albeit not without some ambiguity. On our story, Descartes’ metaphysics and epistemology are not driven by concerns about deception _per se_, but by concerns about God’s _benevolence_. (shrink)

The essence of who we are depends on our brains. They enable us to think, to feel joy and sorrow, communicate through speech, reflect on the moments of our lives, and to anticipate, plan for, and worry about our imagined futures. Although some of our abilities are comparatively new, key features of our behavior have deep roots that can be traced to the beginning of life. By following the story of behavior, step-by-step, over its roughly four-billion-year trajectory, we come to (...) understand both how similar we are to all organisms that have ever lived, and how different we are from even our closest animal relatives. We care about our differences because they are ours. But differences do not make us superior; they simply make us different. (shrink)

The overarching goal in the seventh edition of this text remains what it was for the first edition: "to provide a clear, concise, and reasonably comprehensive introductory survey of the ethical choices available to us in business." This book arose from the challenges encountered in my own teaching of business ethics. Over the years I have taught business ethics in many settings and with many formats. I sometimes relied on an anthology of readings, other times I emphasized case studies.

This important collection of essays is a synthesis of foundational studies in Bayesian decision theory and statistics. An overarching topic of the collection is understanding how the norms for Bayesian decision making should apply in settings with more than one rational decision maker and then tracing out some of the consequences of this turn for Bayesian statistics. There are four principal themes to the collection: cooperative, non-sequential decisions; the representation and measurement of 'partially ordered' preferences; non-cooperative, sequential decisions; and pooling (...) rules and Bayesian dynamics for sets of probabilities. The volume will be particularly valuable to philosophers concerned with decision theory, probability, and statistics, statisticians, mathematicians, and economists. (shrink)

Over the past half century, our best scientific understanding of the immune system has been transformed. The immune system has turned out to be extremely sophisticated, densely connected to the central nervous system and cognitive capacities, deeply involved in the production of behaviour, and responsive to different kinds of psychosocial event. Such results have rendered the immune system part of the subject-matter of psychology and cognitive science. I argue that such results, alongside the history of psychoneuroimmunology, give us good reason (...) to be sceptical about the characterization of cognitive science and psychology as studying the mind and the mental.

How far has the Darwinian revolution come? To what extent have evolutionary ideas penetrated into the social sciences and humanities? Are the “science wars” over? Or do whole blocs of disciplines face off over an unbridgeable epistemic gap? To answer questions like these, contributors to top journals in 22 disciplines were surveyed on their beliefs about human nature, culture, and science. More than 600 respondents completed the survey. Scoring patterns divided into two main sets of disciplines. Genetic influences were emphasized (...) in the evolutionary social sciences, evolutionary humanities, psychology, empirical study of the arts, philosophy, economics, and political science. Environmental influences were emphasized in most of the humanities disciplines and in anthropology, sociology, education, and women's or gender studies. Confidence in scientific explanation correlated positively with emphasizing genetic influences on behavior, and negatively with emphasizing environmental influences. Knowing the current actual landscape of belief should help scholars avoid sterile debates and ease the way toward fruitful collaborations with neighboring disciplines. (shrink)

In “Is semantics possible?” Putnam connected two themes: the very possibility of semantics (as opposed to formal model theory) for natural languages and the proper semantic treatment of common nouns. Putnam observed that abstract semantic accounts are modeled on formal languages model theory: the substantial contribution is rules for logical connectives (given outside the models), whereas the lexicon (individual constants and predicates) is treated merely schematically by the models. This schematic treatment may be all that is needed for an account (...) of validity in a formal setting, but it does not help to understand how proper and common nouns function in reality (not in models). Putnam then initiated the empirical study of such nouns to indicate, (i), that the popular Frege-Carnap account of them as (“disguised” compound) predicates is empirically incorrect, and, (ii), that they offer a new paradigm for a naturalistic semantics of natural languages. We take Putnam’s program a couple of steps further. First, we investigate the semantics of common nouns and argue that they refer (to kinds), rather than apply by satisfaction/truth to a designation/denotation. Second, we point to general results about semantics as a theory whose fulcrum is the reference relation rather than satisfaction in models and validity across them. (shrink)

The history of philosophy is a history of moral circle expansion. This history correlates with a history of expansionism about consciousness. Recently, expansionism about consciousness has exploded: to invertebrates, to plants, to logic gates, and to fundamental entities. The last of these expansions stems from a surge of interest in panpsychism. In an exploratory spirit, this paper considers some largely uncharted territory: the ethical implications of panpsychism. Our conclusion is that while panpsychism probably does significantly expand our moral circle, it's (...) also probably short on anything of practical significance. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Friendship: The Future of an Ancient Gift by Claudia BaracchiJoseph GamacheBARACCHI, Claudia. Friendship: The Future of an Ancient Gift. Translated by Elena Bartolini and Catherine Fullarton. Bloomington: Indiana University Press, 2023. 146 pp. Paper, $30.00Friendship: The Future of an Ancient Gift offers a series of reflections on friendship that "outline thoughts, visions, stories." It is well to bear this in mind. There is no sustained discussion of (and (...) not many references to) other commentators or interpreters of the ancient Greeks. Nor is there, despite the title, a sustained philosophical treatment of friendship or its future. It is a series of reflections on ancient Greek texts. These reflections are unified by the theme of friendship, even when friendship seems to recede into the background. Each chapter is organized around a specific text, the reading of which is interspersed with the aforementioned thoughts, visions, and stories.The first chapter focuses on Plato's Timaeus. Friendship in its "most elementary sense" is "looking at the sky" and seeing not only myself, but "myself as us." This sort of cosmic friendship is a look, a "unitive force, a capacity for seeing the bonds and holding together the elements that form every living organism." The second chapter takes up the analogy of the soul and the city in the Republic. I am a friend to myself when the parts of my soul are in harmony.In the third and longest chapter, Baracchi takes up friendship between equals as discussed in the Nicomachean Ethics. The thematic focus is now friendship between persons, and we read that friendship is a "privileged place in which to be," that it "corroborates, strengthens, amplifies, and emphasizes" the friends, that it is the "condition and context for the utmost explication of human dynamis." Friends resemble each other like poetic images "that illuminate and elucidate one another." The third chapter also takes a swipe at "us moderns," whose notions of liberty undermine our ability to appreciate friendship. We moderns "struggle to contemplate seriousness, fidelity, and the depth they entail, without cynicism." The critique is familiar, and trades, at times, on what seems to be a conflation of Hobbes with the entirety of early modern philosophical anthropology. [End Page 535]Chapters 4 through 6 return to Plato, first with a reflection on the Apology and Symposium, and then with a discussion of Aristotle's friendship with Plato. The fifth chapter takes up the tension between the pursuit of truth and the love of one's friends, as that dilemma manifests in the life of a philosopher. Baracchi convincingly argues that Aristotle should be read as honoring the deeper teachings of Plato, and Socrates before him, that one should care about not who holds a belief but only whether the belief is true. Thus did Aristotle resolve the dilemma between truth and friendship. His pursuit of the truth, even when it caused disagreement with Plato, was an act of friendship.Chapter 6 focuses on the origin of the polis as described in the Republic. Baracchi shows how Socrates tries in the Republic to widen the circle of those who count as one's friends, from select others within the polis, to everyone within the polis, to the entire Greek world, as well as to push back against those who argue that enmity is the necessary foundation of the polis. The last three chapters of the book return to Aristotle's views about friendship: first, about the relationship between friendship and justice, second, about friendships between unequals, and lastly, about the embodied aspects of friendship, its sweetness, and pleasure.There are limits, however, to how helpful the work might be to philosophers interested in friendship. The language is often too abstract, as in the recommendation, "to learn to think human community in its entirety, without this entailing the elimination of differences, and without reducing the differences to identity-related and localistic velleities." Or in the claim that the difference between complete and derivative friendship is the former's ability to "to grasp the broader reasons in the finite, and thus to place the contingent in an otherwise articulated context." Too often there are exaggerations that obscure whatever point is... (shrink)

When can a Bayesian investigator select an hypothesis H and design an experiment to make certain that, given the experimental outcome, the posterior probability of H will be lower than its prior probability? We report an elementary result which establishes sufficient conditions under which this reasoning to a foregone conclusion cannot occur. Through an example, we discuss how this result extends to the perspective of an onlooker who agrees with the investigator about the statistical model for the data but who (...) holds a different prior probability for the statistical parameters of that model. We consider, specifically, one-sided and two-sided statistical hypotheses involving i.i.d. Normal data with conjugate priors. In a concluding section, using an "improper" prior, we illustrate how the preceding results depend upon the assumption that probability is countably additive. (shrink)

Frankfurt‐style action cases have been immensely influential in the free will and moral responsibility literatures because they arguably show that an agent can be morally responsible for a behavior despite lacking the ability to do otherwise. However, even among the philosophers who accept Frankfurt‐style action cases, there remains significant disagreement about whether also to accept Frankfurt‐style omission cases – cases in which an agent omits to do something, is unable to do otherwise, and is allegedly morally responsible for that omission. (...) Settling this debate about Frankfurt‐style omission cases is significant because the resolution entails an important fact about moral responsibility: whether there is there a moral asymmetry between actions and omissions with respect to the ability to do otherwise. My proposal is that both Frankfurt‐style action cases and omission cases involve the same type of causal structure: causal preemption. However, the preemptor and the preemptee differ. In action cases, the Frankfurted agent preempts the neuroscientist and is causally and morally responsibility for the effect. In omission cases, Frankfurted agent is neither causally nor morally responsible for the effect. Instead, the neuroscientist preempts the Frankfurted agent. Thus, there are no Frankfurt‐style omission cases. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Dramatization of Absolute Idealism:Gabriel Marcel and F. H. BradleyJoseph GamacheI. IntroductionThis paper consists of an observation, a suggestion, and an illustration. First, the observation: in the English-language literature on the philosophy of Gabriel Marcel, there is, so far as I have discovered, a lack of attention paid to the relationship between Marcel and the British philosopher F. H. Bradley (1846–1924).1 Why might be this be? I speculate (this (...) is not the suggestion previously advertised) that the following are possible reasons for this omission. First, Bradley's influence is neglected in favor of what some might regard as the more obvious influence of Josiah Royce (1855–1916). After all, Marcel wrote a series of articles on Royce early in his career that were subsequently published as a monograph and eventually translated into English as Royce's Metaphysics. Second, there is the confluence of narratives concerning Marcel's philosophical development and the dethronement of Bradley and of idealism by figures such as Russell and Moore. According to the former narrative, Marcel's idealist phase ends with the first part of the Metaphysical Journal (about 1915).2 Since Bradley is less widely read these days and is treated simply as one more (even if the chief) representative of British idealism, it is easy to infer that, when he shed his idealism, Marcel also shed any connection with Bradley.But all that I have achieved thus far is the articulation of two reasons why people interested in Marcel have not also been interested in Bradley. Are there any reasons to believe that Marcel was influenced by Bradley in a positive way? Here, we can do no better than to gather some selected texts. In his preface to the English translation of the Metaphysical Journal, Marcel writes: [End Page 17]Meditations on the implications of the word "with" and on metaphysical fruitfulness must in my opinion be counted among the most valuable contributions of the Metaphysical Journal. Later, in the collected writings published under the title Du Refus à l'invocation [translated into English as Creative Fidelity], I was to submit to similar analyses the relations, or rather the super-relations, implies by the French word "chez." Here, unless I am mistaken, I made use of the word super-relation for the first time. The vigorous criticism made by F. H. Bradley (in Appearance and Reality) of the current notion of relation—considered as a pure makeshift—is there extended, and I think I will be never be able to recognize too explicitly what I owe to that great thinker.(Marcel, Metaphysical Journal xii)In the foreword to his pre-Metaphysical Journal works published as Philosophical Fragments 1909–1914, Marcel writes of his early (idealist) phase:I find it hard to understand today how, during the years immediately following the reception of my aggregation degree, and even after having had the privilege of hearing Henri Bergson at the College de France, I could still feel the need to undertake a groping inquiry in such a rarefied atmosphere and with the help of tools borrowed from post-Kantian philosophy. Bradley—I had read Appearance and Reality—should have helped me shake off the strait jacket in which my thought was so tightly bound.(Marcel, Philosophical Fragments 23)In addition to these quotations, I might also add (a) that Marcel had wanted to write a thesis on Bradley, but that the idea had already been claimed by a fellow student (Marcel, Awakenings 74; "Autobiographical Essay" 18), and (b) the existence of a correspondence between Marcel and Bradley in the year 1920, which includes Marcel's sharing with Bradley his articles on Royce.3 Putting this all together, the following picture emerges. Bradley influenced Marcel as a student and in his idealist years, and beyond his idealist years, as the above references suggest.So much for the observation; now for the suggestion. I suggest that Marcel can be read as, in various places throughout his corpus, dramatizing certain Bradleyan themes, thereby drawing out the ontological weight—to use Marcel's phrase—of Bradley's philosophical positions. There is some evidence for this suggestion in Marcel's self-reflection in The Existential... (shrink)

Does the Second Amendment protect those who threaten others by negligently or recklessly wielding firearms? What line separates constitutionally legitimate gun displays from threatening activities that can be legally proscribed?

Van Leeuwen’s Religion as Make-Believe, A Theory of Belief, Imagination, and Group Identity argues that religious and political beliefs are fundamentally different from mundane, factual beliefs and represent a cognitive attitude more akin to imagining. To ground this difference, Van Leeuwen proposes four principles defining factual beliefs: ‘involuntariness’ mandates that people cannot choose what they believe; ‘no compartmentalization’ says that factual – but not religious – beliefs guide behavior in all domains; ‘cognitive governance’ requires that inferences be readily drawn from (...) factual beliefs; ‘evidential vulnerability' entails that beliefs are revised given contradictory evidence. While factual beliefs are supposed to meet these standards, Van Leeuwen marshals evidence that religious and tribal beliefs – or “credences” – fail to obey these four principles. In this commentary, I argue that beliefs – both factual and religious – are often much more complicated than Van Leeuwen assumes. This complexity makes perfect conformity to the four principles unlikely, even for factual beliefs. I review Van Leeuwen’s evidence for credences and suggest that this evidence is compatible with the null hypothesis: that religious beliefs are simply beliefs. (shrink)

The concept of free will is fraught with controversy, as readers of this volume likely know. Philosophers disagree about what free will is, whether we have it, what mitigates or destroys it, and what it's good for. Indeed, philosophers even disagree about how to fix the referent of the term 'free will' for purposes of describing and exploring these disagreements. What one person considers a reasonably neutral working definition of 'free will' is often considered question-begging or otherwise misguided by another. (...) Such disputes make it difficult to summarize the problem of free will, roughly the debate over the nature and existence of free will, in a clear and uncontentious way. In generic terms, however, the two basic solutions to the problem of free will are free-willism, the view that we have free will, and free-will denialism, i.e. the view that we do not have free will. As stated here, neither denialism nor free-willism constitutes a complete solution to the problem of free will; to be complete, a proposed solution must also tell us a convincing story about what free will is and that, as it turns out, is a very difficult task indeed. One historically popular way of approaching the problem of free will is to ask about the relationship between free will and determinism: "Does free will stand in relation R to determinism: yes or no?" This is just a template for a question, of course. To transform this template-question into a substantive question with a clear meaning, we need to flesh out the template's free-will relatum, its determinism relatum, and give a precise value to relation R. There is, however, no uncontroversial way to do this. In addition to the standard difficulties raised by fixing the referent of 'free will', philosophers hold radically different views about what is-or should be-meant by 'determinism', Shabo ), and they identify relations which are as substantively different as correlation and causation when characterizing relation R. In practical terms, then, it may be best to think of the problem of determinism as a loose collection of disagreements about how to best spell out and answer the template-question, and how asking and answering such questions would help us to solve the problem of free will.

Directional deep brain stimulation contacts provide greater spatial flexibility for therapy than traditional ring-shaped electrodes, but little is known about longitudinal changes of impedance and orientation. We measured monopolar and bipolar impedance of DBS contacts in 31 patients who underwent unilateral subthalamic nucleus deep brain stimulation as part of a randomized study. At different follow-up visits, patients were assigned new stimulation configurations and impedance was measured. Additionally, we measured the orientation of the directional lead during surgery, immediately after surgery, and (...) 1 year later. Here we contrast impedances in directional versus ring contacts with respect to local anatomy, active stimulation contact, and over time. Directional contacts display larger impedances than ring contacts. Impedances generally increase slightly over the first year of therapy, save for a transient decrease immediately post-surgery under general anesthesia during pulse generator placement. Local impedances decrease at active stimulation sites, and contacts in closest proximity to internal capsule display higher impedances than other anatomic sites. DBS leads rotate slightly in the immediate postoperative period but otherwise remain stable over the following year. These data provide useful information for setting clinical stimulation parameters over time. (shrink)

This article examines the benefits of incorporating religious reflection into the psychology of religion and vice versa. By applying Bayes’ theorem, we discover that scientists and theologians can collaborate without sharing prior beliefs. Instead, rationality requires updating our beliefs before data collection in response to the degree of surprise generated by the data. Moreover, although people who start with different beliefs may become more aligned after data collection, rationality does not entail a convergence to identical beliefs. To illustrate the potential (...) for growth in understanding from greater collaboration between theologians and scientists, I examine a longitudinal investigation of religion after a natural disaster. This case study illustrates how conversations between theological and psychological perspectives on religion can lead to a more comprehensive understanding of virtue cultivation, benefiting both science and theology.

There are few industries in which decisions are so intently scrutinized by millions of Canadians as the healthcare industry. Each and every day important decisions concerning the funding and delivery of healthcare are made away from the clinic and in the offices of administrators and policy makers. This book is designed to assist the current and future healthcare administrator to render effective and ethical decisions. Health administration ethics functions as a bridge between business ethics and clinical ethics. This book forges (...) the essential link between the foundational concepts of ethics theories, principles, and codes and the science of decision making. It takes a case study approach and introduces a new, user-friendly decision-making model. There is currently no Canadian textbook designed to guide administration decisions within the Canadian healthcare system, making this textbook unique in the market. (shrink)
