One of the more serious criticisms of the B-theory is that by denying the passage of time or maintaining that passage is a mind-dependent illusion or appearance, the B-theory gives rise to a static, block universe and thereby removes what is most distinctively timelike about time. The aim of this paper is to discuss the R-theory of time, after Russell, who Richard Gale calls “the father of the B-theory,” and explain how the R-theory can respond to the criticisms just (...) raised, and others. In the course of my discussion I shall clarify differences between versions of the A-, B- and R-theories of time, and argue that McTaggart’s conception of the B-series and more specifically, the B-relations that generate it, has been instrumental in misconstruing the A-/B-theory debate resulting in criticisms of the B-theory that can be seen to be fallacious when applied to the R-theory.

This article evaluates an emerging element in popular debate and inquiry: DYOR. (Haven’t heard of the acronym? Then Do Your Own Research.) The slogan is flexible and versatile. It is used frequently on social media platforms about topics from medical science to financial investing to conspiracy theories. Using conceptual and empirical resources drawn from philosophy and psychology, we examine key questions about the slogan’s operation in human cognition and epistemic culture.

What makes for a good education? What does one need to count as well-educated? Knowledge, to be sure. But knowledge is easily forgotten, and today's knowledge may be obsolete tomorrow. Skills, particularly in critical thinking, are crucial as well. But absent the right motivation, graduates may fail to put their skills to good use. In this book, Nathan King argues that intellectual virtues-traits like curiosity, intellectual humility, honesty, intellectual courage, and open-mindedness-are central to any education worthy of the name. (...) Further, such virtues are crucial to our functioning well in everyday life, in areas as diverse as personal relationships, responsible citizenship, civil discourse, and personal success. Our struggles in these areas often result from a failure to think virtuously. Drawing upon recent work in philosophy and psychology, King paints a portrait of virtuous intellectual character-and of the vices such a character opposes. Filled with examples and applications, this book introduces readers to the intellectual virtues: what they are, why they matter, and how we can grow in them. (shrink)

I argue that reflection on philosophers who could have been working among us but aren’t can lead us to give up our philosophical beliefs.

Some epistemologists hold that exploration and elaboration of the nature of luck will allow us to better understand knowledge. I argue this is a mistake.

While a growing body of scholarship identifies urban agriculture’s broad suite of benefits and drivers, it remains unclear how motivations to engage in urban agriculture (UA) interrelate or how they differ across cities and types of organizations. In this paper, we draw on survey responses collected from more than 250 UA organizations and businesses from 84 cities across the United States and Canada. Synthesizing the results of our quantitative analysis of responses (including principal components analysis), qualitative analysis of textual data (...) excerpted from open-ended responses, and a review of existing literature, we describe six motivational frames that appear to guide organizations and businesses in their UA practice: Entrepreneurial, Sustainable Development, Educational, Eco-Centric, DIY Secessionist, and Radical. Identifying how practitioners stack functions and frame their work is a first step in helping to differentiate the diverse and often contradictory efforts transforming urban food environments. We demonstrate that a wide range of objectives drive UA and that political orientations and discourses differ by geography, organizational type and size, and funding regime. These six paradigms provide a basic framework for understanding UA that can guide more in-depth studies of the gap between intentions and outcomes, while helping link historically and geographically specific insights to wider social and political economic processes.

History and philosophy complement and overlap each other in subject matter, but the two disciplines exhibit conflict over methodology. Since Hempel's challenge to historians that they should adopt the covering law model of explanation, the methodological conflict has revolved around the respective roles of the general and the particular in each discipline. In recent years, the revival of narrativism in history, coupled with the trend in philosophy of science to rely upon case studies, joins the methodological conflict anew. So long (...) as contemporary philosophy of science relies upon history's methodology to construct its case studies, it subjects itself to a paradoxical situation: the better the history, the worse the philosophy. An example of the methodological conflict is presented in the case of Antoine Lavoisier. This example also serves our ultimateconclusion, which is that distinctively philosophical methods of case-study design promise enhanced prescriptive powers for philosophy of science. (shrink)

This paper concerns the semantics of coordinated if-clauses, as in (1)-(2). It is argued that the meanings of such sentences are explained straightforwardly on theories of conditionals that tie their non- monotonic behaviour to the if-clause itself (e.g. Schlenker 2004, but not theories that tie it to a (covert) modal operator (e.g. Kratzer 1981; 1991). Coordinated if-clauses are revealing of the fine-grained compositional semantics of conditionals.

Contemporary Western culture is experiencing a heightened awareness of religious diversity. This article surveys a range of possible responses to such diversity, and distinguishes between responses that concern the salvation or moral transformation of persons (soteriological views) and those that concern the alethic or epistemic status of religious beliefs (doctrinal views). After providing a brief taxonomy of these positions and their possible relations to one another, the article focuses primarily on competing views about the truth and rationality of religious beliefs (...) (e.g., pluralism, exclusivism, and skepticism). Here a heavy emphasis is placed on arguments for and against the rationality and moral propriety of retaining one's religious beliefs in the face of disagreement. The article surveys some of the more prominent arguments from the literature on this topic and closes with suggestions for further research. (shrink)

The coming of mathematicians to the United States fleeing the spread of Nazism presented a serious problem to the American mathematical community. The persistence of the Depression had endangered the promising growth of mathematics in the United States. Leading mathematicians were concerned about the career prospects of their students. They feared that placing large numbers of refugees would exacerbate already present nationalistic and anti-Semitic sentiments. The paper surveys a sequence of events in which the leading mathematicians reacted to the foreign-born (...) and to the spread of Nazism, culminating in the decisions by the American Mathematical Society to found the journal Mathematical reviews and to form a War Preparedness Committee in September 1939. The most obvious consequence of the migration was an enlarged role for applied mathematics. (shrink)

In this candid autobiographical essay, Nathan Salmon recounts and assesses the impact of various philosophers and events on his philosophical development.

The ‘species problem’ can be characterized, to a first approximation, as the task of providing a viable species concept —that is, a functional analysis that picks out the ‘right’ kind of biological entities. After decades of debate and centuries of taxonomic practice, no overarching consensus has been reached. The individuation and definition of the units of evolution and classification, species included, remains controversial. If anything, there now seems to be more disagreement than ever before.

This paper is designed to help people rationally engage moral issues regarding the treatment of animals, specifically uses of animals in medical and psychological experimentation, basic research, drug development, education and training, consumer product testing and other areas.

This essay presents a model-theoretic account of dispositional properties, according to which dispositions are not ordinary properties of real entities; dispositions capture the behavior of abstract, idealized models. This account has several payoffs. First, it saves the simple conditional analysis of dispositions. Second, it preserves the general connection between dispositions and regularities, despite the fact that some dispositions are not grounded in actual regularities. Finally, it brings together the analysis and the explanation of dispositions under a unified framework.

Six recently discussed problems in discrete probabilistic sample space, which have been found puzzling and even paradoxical, are reexamined. The importance is stressed of a sharp distinction between the formalization of mathematical problems and their formal solution that, applied to probability theory, must lead through the explicit partitioning of a sample space. If this approach is consistently followed, such problems reveal themselves to be either inherently ambiguous, and therefore without solution, or quite straightforward. In both cases nothing remains of any (...) sense of paradox. (shrink)

_Introduction:_ Clinically relevant information can go uncaptured in the conventional scoring of a verbal fluency test. We hypothesize that characterizing the temporal aspects of the response through a set of time related measures will be useful in distinguishing those with MCI from cognitively intact controls. _Methods:_ Audio recordings of an animal fluency test administered to 70 demographically matched older adults (mean age 90.4 years), 28 with mild cognitive impairment (MCI) and 42 cognitively intact (CI) were professionally transcribed and fed into (...) an automatic speech recognition (ASR) system to estimate the start time of each recalled word in the response. Next, we semantically cluster participant generated animal names and through a novel set of time-based measures, we characterize the semantic search strategy of subjects in retrieving words from animal name clusters. This set of time-based features along with standard count-based features (e.g., number of correctly retrieved animal names) were then used in a machine learning algorithm trained for distinguishing those with MCI from CI controls. _Results:_ The combination of both count-based and time-based features, automatically derived from the test response, achieved 77% on AUC-ROC of the support vector machine (SVM) classifier, outperforming the model trained only on the raw test score (AUC, 65%), and well above the chance model (AUC, 50%). _Conclusion:_ This approach supports the value of introducing time-based measures to the assessment of verbal fluency in the context of this generative task differentiating subjects with MCI from those with intact cognition.

What is a discourse? What makes a discourse coherent or incoherent? Investigation into these difficult questions has yielded so many sophisticated proposals that a short, comprehensive survey is well out of reach.

Which intermediate propositional logics can prove their own completeness? I call a logic reflexive if a second-order metatheory of arithmetic created from the logic is sufficient to prove the completeness of the original logic. Given the collection of intermediate propositional logics, I prove that the reflexive logics are exactly those that are at least as strong as testability logic, that is, intuitionistic logic plus the scheme $\neg φ ∨ \neg\neg φ. I show that this result holds regardless of whether Tarskian (...) or Kripke semantics is used in the definition of completeness. I also show that the operation of creating a second-order metatheory is injective, thereby insuring that I am actually considering each logic independently. (shrink)

Regarding Cicero’s “sincerity” in the Pro Marcello (46 BCE), interpretative ore resides in Ad familiares 4.4, an artfully composed letter to Servius Sulpicius from fall 46, preserved in a posthumously edited letter-book (Ad familiares Book 4) about civil war and its aftermath. In these minor-key renditions of the dramatic senate scene, Caesar’s pardon of Marcellus, and Cicero’s subsequent speech of thanks, darker themes evoke dissonant, despondent voicings, and Cicero’s response to Caesar’s act rings less sincere than ironic. Read in this (...) vein, Fam. 4.4 reveals the different roles Cicero performs in speech and letter—wise counselor, despairing dissident—and the issue becomes Cicero’s performance of sincerity in context, as well as the editor’s framing of Cicero’s report of his performance. Indeed, these three texts—speech, letter, letter in letter-book—constitute diverse configurations of a single historical event, and the variance among them yields a richer find in the sediments of Roman history.

The law of armed conflict prevents the coerced extraction of information from Prisoners of War (PoWs). We claim, however, that the letter of that law involves too broad a concept of coercion. On a natural reading, there is a sense in which any extraction of information—by any method—is coercive. We respect the notion that PoWs ought not be treated poorly, but we argue “coercion” should not be understood so broadly. With respect to its use in international law, we favor a (...) moralized notion of “coercion,” as opposed to a non-moralized one. We explain what this means, and argue why this is a better reading of the law. We think a moralized notion of coercion is more intuitive, is more in line with both actual practice and the intent of the framers of international law, and has practical benefits as well. (shrink)

In his reply to the Nobis-Graham review of Tibor Machan's book, Putting Humans First, John Altick defends Machan's and Rand's theories of moral rights, specifically as they relate to the rights of non-human animals and non-rational human beings. Nobis and Graham argue that Altick's defense fails and that it would be wrong to eat, wear, and experiment on non-rational—yet conscious and sentient—human beings. Since morally relevant differences between these kinds of humans and animals have not been identified to justify a (...) difference in treatment or consideration, it is wrong to harm animals for these purposes also.

Short-term international medical outreach experiences are becoming more popular among medical students. As the popularity of these trips grows, participants, scholars, and institutions have become more aware of the potential pitfalls of such experiences. Loyola University Chicago Stritch School of Medicine has an approximately 20-year international service immersion program that has sent more than 1,400 participants to more than 30 countries. Recently, ISI programming has been adjusted to provide students more formal sessions exploring the ethics of the ISI trips. Students (...) are required to attend both pre- and post-trip educational sessions covering a wide range of relevant global health topics as well as participating in in-country reflections and post-trip debriefings. This recent adjustment has evolved further to become the foundation for the SSOM’s four-year Global Health Honors program that not only encourages an ethical foundation for the student’s ISI experience but also hopes to provide a foundation for students as they look toward a future career in global health.
