Causal reductionism is the widespread assumption that there is no room for additional causes once we have accounted for all elementary mechanisms within a system. Due to its intuitive appeal, causal reductionism is prevalent in neuroscience: once all neurons have been caused to fire or not to fire, it seems that causally there is nothing left to be accounted for. Here, we argue that these reductionist intuitions are based on an implicit, unexamined notion of causation that conflates causation with prediction. (...) By means of a simple model organism, we demonstrate that causal reductionism cannot provide a complete and coherent account of ‘what caused what’. To that end, we outline an explicit, operational approach to analyzing causal structures. (shrink)

The application of machine learning in health care holds great promise for improving care. Indeed, our own team is collaborating with experts in machine learning and statistical modeling to bu...

We model the forgetting of propositional variables in a modal logical context where agents become ignorant and are aware of each others’ or their own resulting ignorance. The resulting logic is sound and complete. It can be compared to variable-forgetting as abstraction from information, wherein agents become unaware of certain variables: by employing elementary results for bisimulation, it follows that beliefs not involving the forgotten atom(s) remain true.

Rapid advancements in artificial intelligence and machine learning (AI/ML) in healthcare raise pressing questions about how much users should trust AI/ML systems, particularly for high stakes clinical decision-making. Ensuring that user trust is properly calibrated to a tool’s computational capacities and limitations has both practical and ethical implications, given that overtrust or undertrust can influence over-reliance or under-reliance on algorithmic tools, with significant implications for patient safety and health outcomes. It is, thus, important to better understand how variability in trust (...) criteria across stakeholders, settings, tools and use cases may influence approaches to using AI/ML tools in real settings. As part of a 5-year, multi-institutional Agency for Health Care Research and Quality-funded study, we identify trust criteria for a survival prediction algorithm intended to support clinical decision-making for left ventricular assist device therapy, using semistructured interviews (n=40) with patients and physicians, analysed via thematic analysis. Findings suggest that physicians and patients share similar empirical considerations for trust, which were primarilyepistemicin nature, focused on accuracy and validity of AI/ML estimates. Trust evaluations considered the nature, integrity and relevance of training data rather than the computational nature of algorithms themselves, suggesting a need to distinguish ‘source’ from ‘functional’ explainability. To a lesser extent, trust criteria were also relational (endorsement from others) and sometimes based on personal beliefs and experience. We discuss implications for promoting appropriate and responsible trust calibration for clinical decision-making use AI/ML. (shrink)

When the Supreme Court in 2003 struck down a Texas law prohibiting homosexual sodomy, it cited the right to privacy based on the guarantee of "substantive due process" embodied by the Constitution. But did the court act undemocratically by overriding the rights of the majority of voters in Texas? Scholars often point to such cases as exposing a fundamental tension between the democratic principle of majority rule and the liberal concern to protect individual rights. Democratic Rights challenges this view by (...) showing that, in fact, democracy demands many of these rights. Corey Brettschneider argues that ideal democracy is comprised of three core values--political autonomy, equality of interests, and reciprocity--with both procedural and substantive implications. These values entitle citizens not only to procedural rights of participation but also to substantive rights that a "pure procedural" democracy might not protect. What are often seen as distinctly liberal substantive rights to privacy, property, and welfare can, then, be understood within what Brettschneider terms a "value theory of democracy." Drawing on the work of John Rawls and deliberative democrats such as Jürgen Habermas, he demonstrates that such rights are essential components of--rather than constraints on--an ideal democracy. Thus, while defenders of the democratic ideal rightly seek the power of all to participate, they should also demand the rights that are the substance of self-government. (shrink)

Drawing on the work of Robert Nozick and Johann Gottlieb Fichte, the author argues that human self-consciousness cannot be explained in naturalistic terms. Instead, it is a spontaneous phenomenon.

Luck, Value, and Commitment comprises eleven new essays which engage with, or take their point of departure from, the influential work in moral and political philosophy of Bernard Williams (1929-2003).

Several tasks in artificial intelligence require the ability to find models about knowledge dynamics. They include belief revision, fusion and belief merging, and abduction. In this paper, we exploit the algebraic framework of mathematical morphology in the context of propositional logic and define operations such as dilation or erosion of a set of formulas. We derive concrete operators, based on a semantic approach, that have an intuitive interpretation and that are formally well behaved, to perform revision, fusion and abduction. Computation (...) and tractability are addressed, and simple examples illustrate the main results. (shrink)

Food security policy, programs, and infrastructure have been incorporated into Public Health and other areas of the Provincial Government in British Columbia, including the adoption of food security as a Public Health Core Program. A policy analysis of the integration into Public Health is completed by merging findings from 48 key informant interviews conducted with government, civil society, and food supply chain representatives involved in the initiatives along with relevant documents and participant/direct observations. The paper then examines the results within (...) the context of historic and international trends and theoretical models of food policy, community food security, and applied policy research. Public Health re-emerged as a driver of food security in BC—both as a key player and in positing the public’s health as a driver in food security and food systems. While Public Health’s lead role supported an increase in legitimacy for food security in BC, interviewees described a clash of cultures between Public Health and civil society. The clash of cultures occurred partly as a result of Public Health’s limited food security mandate and top down approach. Consequently civil society voice at the provincial level was marginalized. A social policy movement toward a new political paradigm—regulatory pluralism—calls for greater engagement of civil society, and for all sectors to work together toward common goals. A new, emerging policy map is proposed for analyzing the dynamics of food security and health promotion initiatives in BC. (shrink)

The principles whereby the reason operates in ethically complicated situations has been subject to long-standing debates in Catholic Philosophy. A classic text which exemplifies this is Aquinas’s consideration of self-defensive killing. In this paper I clarify two central issues in double-effect reasoning debates surrounding this text. Both issues are connected to the seemingly simple but actually complex task of accounting for the “chosen means” of self-defense. The first issue is whether the “chosen means” are also able to be considered a (...) “proximate end,” to which the intention is directed. The second is determining whether the assailant’s death is related to the “chosen means” per se and therefore to the rest of the moral action. Resolving these issues will provide grounds for answering the broader question implicit in the situation of self-defensive killing: what is to be done when human actions would inevitably entail that some evil is instrumentally tied to realizing some good?

Sir Ernst Gombrich and the Barber from Tuscany In the spirit of Sir Ernst Gombrich, this essay uses an anecdote—a chat between Gombrich and a barber from Tuscany—to illustrate a deeper point, namely, how cultural memory, tradition, and a canon give rise to an implied language of culture and cultural value. Gombrich staunchly defended tradition against relativism. By relativism, he meant something like "radical subjectivism." To his mind, subjectivism (in the cultural and social sense of the term) is not only (...) impossible, since meaning is conferred through culture and society, but it is also dangerous (in the cultural and ethical sense of the term), since it denies the existence of shared values. Against consensus on the one hand and radical subjectivism on the other, Gombrich advocated a middle way: criticism and self-criticism to ensure latitude; the search for "truth" to ensure a limited plurality of interpretations.

A deaf scientist, who teaches deaf physics students, writes about deaf people throughout history who overcame negative attitudes to contribute significantly to various fields of science. He also discusses education, including the establishment of Gallaudet University, and suggests ways representation of deaf people could be increased in the scientific community.

The history of Western philosophy is predominantly a history of written texts, but philosophers have lived in that history and looked back at it as if a dependence on such unusual and complex artifacts had nothing to do with the work of philosophy itself. The assumption behind this notion of a literary “museum without walls” is that philosophical meaning is self-generating and transparent—that both the medium and form of philosophical texts as they appear to the reader are accidental causes, with (...) no significant consequences for philosophical meaning itself.

Biblical Christianity should be a powerful, life-forming, paradigm-shifting experience leading to increasing levels of Christlikeness. Unfortunately, the experience of many Christians today is far short of the transformation described in Scripture. This article reports on a portion of mixed-methods research examining the transformative learning reported by alumni of a 22-lesson discipleship process called the Immersion Experience by Aphesis Group Ministries. Holistic spiritual health involves listening to our emotions, confronting toxic shame, addressing childhood defenses, and untangling our distorted spirituality.
