Can God create a stone too heavy for him to lift? Can time have a beginning? Which came first, the chicken or the egg? Riddles, paradoxes, conundrums--for millennia the human mind has found such knotty logical problems both perplexing and irresistible. Now Roy Sorensen offers the first narrative history of paradoxes, a fascinating and eye-opening account that extends from the ancient Greeks, through the Middle Ages, the Enlightenment, and into the twentieth century. When Augustine asked what God was doing (...) before He made the world, he was told: "Preparing hell for people who ask questions like that." A Brief History of the Paradox takes a close look at "questions like that" and the philosophers who have asked them, beginning with the folk riddles that inspired Anaximander to erect the first metaphysical system and ending with such thinkers as Lewis Carroll, Ludwig Wittgenstein, and W.V. Quine. Organized chronologically, the book is divided into twenty-four chapters, each of which pairs a philosopher with a major paradox, allowing for extended consideration and putting a human face on the strategies that have been taken toward these puzzles. Readers get to follow the minds of Zeno, Socrates, Aquinas, Ockham, Pascal, Kant, Hegel, and many other major philosophers deep inside the tangles of paradox, looking for, and sometimes finding, a way out. Filled with illuminating anecdotes and vividly written, A Brief History of the Paradox will appeal to anyone who finds trying to answer unanswerable questions a paradoxically pleasant endeavor.

In _Plato on Democracy and Political technē_ Anders Dahl Sørensen offers an in-depth investigation of Plato’s discussions of democracy’s ‘epistemic potential’, arguing that this question is far more central to his political thought than is usually assumed.

Are there are normative reasons to have – or refrain from having – certain emotions? The dominant view is that there are. I disagree. In this paper, I argue for Strong Eliminativism – the view that there are no reasons for emotions. My argument for this claim has two premises. The first premise is that there is a deliberative constraint on reasons: a reason for an agent to have an attitude must be able to feature in that agent’s deliberation to (...) that attitude. My argument for this premise is that in order to have reasons for an attitude, we need to be able to exhibit some relevant form of control over this attitude, and this relevant form of control is deliberative control. The second premise is that no one can deliberate to any emotion. My argument for this premise turns on the claim that there is no deliberative question that is settled by forming (or giving up) an emotion. I contend that this is so due to the well-known phenomenon of recalcitrant emotions: for any deliberative question that can be settled, there is no guarantee that the relevant emotional state will follow (or be revised). Strong Eliminativism follows from these two premises. (shrink)

An entertaining history of the idea of nothing - including absences, omissions, and shadows - from the Ancient Greeks through the 20th century How can nothing cause something? The absence of something might seem to indicate a null or a void, an emptiness as ineffectual as a shadow. In fact, 'nothing' is one of the most powerful ideas the human mind has ever conceived. This short and entertaining book by Roy Sorensen is a lively tour of the history and (...) philosophy of nothing, explaining how various thinkers throughout history have conceived and grappled with the mysterious power of absence -- and how these ideas about shadows, gaps, and holes have in turned played a very positive role in the development of some of humankind's most important ideas. Filled with Sorensen's characteristically entertaining mix of anecdotes, puzzles, curiosities, and philosophical speculation, the book is ordered chronologically, starting with the Taoists, the Buddhists, and the ancient Greeks, moving forward to the middle ages and the early modern period, then up to the existentialists and present day philosophy. The result is a diverting tour through the history of human thought as seen from a novel and unusual perspective. (shrink)

John Adams vs Thomas Paine: Rival Plans for the Early Republic by historian Jett B. Conner explores how the two rivals helped shape America's first constitutions--the Articles of Confederation and those of several states-- and how they continued contributing to American political thought as it developed during the so-called "critical period" between the adoption of the Articles of Confederation and the start of the Constitutional Convention of 1787. It also focuses on the creation of our democratic republic and compares (...) Paine's and Adams's approaches to structuring constitutions to ensure free government while guarding against abuses of power and the excesses of democratic majorities. (shrink)

International agencies have contributed significantly to the promotion of capital-intensive fisheries development programs in many Third World nations. Activities of both bilateral and multilateral development assistance agencies are examined and shown to have certain common features, notably production-oriented programs typified by the introduction of powerful new fishing technologies, and the promotion of fishery exports as a means of increasing foreign exchange earnings. The argument is advanced that these programs have been largely detrimental to the best interests of recipient nations because (...) they have ignored both resource limitations and the distributional consequences of such development.Fisheries development programs in the Third World are seen as being shaped by a convergence of institutional and class interests between national and international agencies. The perspective of political economy is used to examine these interests and explain their relation to policy outcomes. Evidence is presented to show that international agencies have contributed to dualistic patterns of industry growth which have skewed development benefits towards a narrow urban elite. Rural small-scale fishers have been increasingly marginalized as a result of their inability to compete over a limited and, in some cases, depleted resource.Fisheries development and resource management need to be seen as complementary aspects of a single process rather than as separate activities. Central to fisheries management is the question of resource allocation between competing users. Suggestions are offered by which international development agencies can play an important role in encouraging resource use patterns which are both biologically sustainable and socially just.

By examining how particular ecologies of fashion are connected to the formation of gender, class, and generational identities, this series establishes a new methodology for recording and understanding identity and its connection to style.

Psychedelic or ecodelic medicines (e.g., psilocybin, ayahuasca, iboga) for the care and treatment of addiction, post‐traumatic stress disorder, cancer, cluster headaches, anxiety, and depression have surged to the forefront of discussions about mental health in the US, leading to the emergence of well‐capitalized biotech companies offering multimillion‐dollar IPOs. Venture capital website Pitchbook reports “continuing investor interest and growing acceptance of what until recently was seen as a fringe area of medicine.” As scholars, activists, and practitioners who have been healed by (...) these medicines and applaud the recent wave of decriminalization after a long, strange trip of mass incarceration and widespread dangerous misinformation, we look forward to a culture that makes these medicines available in a safe and affordable way that respects the lineages of the knowledges that are essentially and not accidentally bundled with these plants—Indigenous and counterculture wisdoms for whom these medicines were never “fringe,” but always foundational. In place of corporadelia's pursuit of standardization, we emphasize the care and wisdom of the Indigenous and countercultural teachings—traditions that have made psychedelics available to the emerging corporate/research partnership in the first place. These knowledge traditions offer foils to the ongoing translation of university peer‐reviewed research into market copy, technical articles, and IPOs, and the concomitant emergence of psychedelic pundits. In particular, we examine instances where prominent researchers have overstated the findings of existing clinical trials in public‐facing representations of the field. We argue that these corporate priorities and tactics are being aided by a new wave of psychedelic “thought leaders” who seek to delegitimize non‐hierarchical approaches to knowledge production and community support within a psychedelic commons. While prominent psychedelic psychiatrists and behaviorists are focused on rooting out and transforming individual habits of mind, we argue that there is another, latent potential for psychedelics to draw attention to—and transform—the invisible, hegemonic infrastructures and ideologies that subtly naturalize and perpetuate deeply unequal societies.

You face two buttons. Pushing one will destroy Greensboro. Pushing the other will save it. There is no way for you to know which button saves and which destroys. What ought you to do? Answer: You ought to make the correct guess and push the button that saves Greensboro. Second question: Do you have an obligation to push the correct button?

Can merely thinking about an imaginary situation provide evidence for how the world actually is--or how it ought to be? In this lively book, Roy A. Sorensen addresses this question with an analysis of a wide variety of thought experiments ranging from aesthetics to zoology. Presenting the first general theory of thought experiment, he sets it within an evolutionary framework and integrates recent advances in experimental psychology and the history of science, with special emphasis on Ernst Mach and Thomas (...) Kuhn. Sorensen explores what thought experiments are, how they work, and what their virtues and vices are. In his view, philosophy differs from science in degree, but not in kind. For this reason, he claims, it is possible to understand philosophical thought experiments by concentrating on their resemblance to scientific relatives. Sorensen assesses the hazards of thought experiments and grants that there are interesting ways in which the method leads us astray, but attacks most scepticism about thought experiments as arbitrary. He maintains that they should be used--as they generally are--as part of a diversified portfolio of techniques, creating a network of cross-checks that make for impressive reliability. (shrink)

In Sacred Nature Jerome Stone gives us an informative, earnest introduction to religious naturalism with a focus on its relevance for environmentalism. Environmentalism today often dwells upon warnings about the dire consequences if certain prescribed actions are not taken. Stone takes a different tack. He quotes Aldo Leopold: “Prudence never kindled a fire in the human mind; I have no hope for a conservation born of fear.” Stone’s approach—an engaging one, in my view—is to connect environmentalism with the hope and (...) passion of religious feeling. But Stone’s religious vision does not entail belief in the personalistic, supernatural deity of traditional monotheism. Rather, a sense of the sacred is discovered within... (shrink)

The Real Food Challenge is a national student movement in the United States that aims to shift $1 billion—roughly 20%—of college and university food budgets across the country towards local, ecologically sound, fair, and humane food sources—what they call “real” food—by 2020. The University of Vermont was the fifth university in the U.S. to sign the Real Food Campus Commitment, pledging to shift at least 20% of its own food budget towards “real” food by 2020. In order to examine student (...) preference for “real” food on the UVM campus, we analyzed a survey of 904 undergraduate students that used contingent valuation to evaluate students’ willingness-to-pay for the “real” attribute. We found that a majority of students are willing to pay a positive premium for “real” food. Furthermore, we found that student characteristics and attitudes significantly influence WTP. Specifically, gender, residency, college, and attitudes about price and origin of food are significant predictors of WTP. (shrink)

Seizing the opportunity to apply what they had learned, the students declared a cheating competition. Outspoken participants (future lawyers, politicians, and captains of industry) bragged about their ruses. But to their chagrin, an ethics student prevailed.

Verisimilitude has the potential to deepen the understanding of mathematical progress, the principle of charity, and the psychology of regret. One obstacle is the widely held belief that two statements can vary in truthlikeness only if they vary in what they entail. This obstacle is removed with four types of counterexamples. The first concerns necessarily coextensive measurements that differ only with respect to their units (specifically length, area, and volume). The second class ofcounterexamples is composed of mathematical falsehoods. The third (...) class features inconsistent scientific theories. The fourth class of cases features statements that are instructive but meaningless. (shrink)

Drawing inspiration from the ethical pluralism of G. E. Moore's Principia Ethica, I contend that one empty world can be morally better than another. By ?empty? I mean that it is devoid of concrete entities (things that have a position in space or time). These worlds have no thickets or thimbles, no thinkers, no thoughts. Infinitely many of these worlds have laws of nature, abstract entities, and perhaps, space and time. These non-concrete differences are enough to make some of them (...) better than others. 1I thank Walter Sinnott-Armstrong, John Carroll, and Gideon Rosen for their comments and suggestions.

The vanishing point is a representational gap that organizes the visual field. Study of this singularity revolutionized art in the fifteenth century. Further reflection on the vanishing point invites the conjecture that the self is an absence. This paper opens with perceptual peculiarities of the vanishing point and closes with the metaphysics of personal identity.

THE PURPOSE OF THIS ARTICLE IS TO SHOW HOW HUME’S SCEPTICISM ABOUT MIRACLES GENERATES "EPISTEMOLOGICAL" SCEPTICISM ABOUT TIME TRAVEL. SO THE PRIMARY QUESTION RAISED HERE IS "CAN ONE KNOW THAT TIME TRAVEL HAS OCCURED?" RATHER THAN "CAN TIME TRAVEL OCCUR?" I ARGUE THAT ATTEMPTS TO SHOW THE EXISTENCE OF TIME TRAVEL WOULD FACE THE SAME METHODOLOGICAL PROBLEMS AS THE ONES CONFRONTING ATTEMPTS TO DEMONSTRATE THE EXISTENCE OF PARANORMAL EVENTS. SINCE HUMEAN SCEPTICISM EXTENDS TO THE STUDY OF PARANORMAL EVENTS (PARAPSYCHOLOGY), HUMEANS (...) ARE COMMITTED TO SCEPTICISM ABOUT THE STUDY OF TIME TRAVEL ("PARAHISTORY"). (shrink)

Charitable interpreters of David Hume set aside his sprinkles of piety. Better to read him as lying than as clumsily inconsistent. We argue that the attribution of lies can pay dividends in historical scholarship no matter how strongly the theorist condemns lying. Accordingly, we show that our approach works even with one of the strongest condemners of lying: Immanuel Kant. We argue that Kant lied in his scholarly work and even in the first Critique. And we defend the claim that (...) this lie attribution, strange as it may sound, amounts to a kind of scholarly charity. (shrink)

BackgroundThe use of electronic nicotine delivery systems, also known as vaping, is becoming popular among young adults. Few studies have explored the psychological factors that predict ENDS use and susceptibility in young adults, in addition to known demographic predictors.MethodIn a cross-sectional survey design, 521 young adults, ages 18–25 from the United States, were recruited via Amazon’s Mechanical Turk in 2019, to answer an online survey measuring demographic characteristics and psychological characteristics related to mental health and the Big Five personality traits. (...) The survey also included measures of ENDS ever-use, current use, and susceptibility, which we predicted from the demographic and psychological measures using independent and multiple binary logistic regression analyses.ResultsOf those surveyed, 282 were ENDS ever-users, 93 were current ENDS users, and 61 were ENDS susceptible; 62 were current smokers. Demographically, young adults lower in adulthood socioeconomic-status, not pursuing education further than high school, and current smokers were more likely to be ENDS users. Psychologically, young adults higher in anxiety and lower in conscientiousness more likely to have ever-used ENDS. Lower conscientiousness further predicted current ENDS use and ENDS susceptibility.ConclusionIn this sample of MTurk workers, young adults with experience in vaping were more demographically and psychologically vulnerable than young adults with no experience in vaping. Young adults interested in vaping, but without prior experience, were less conscientious than their non-interested peers. Interventions to target vaping use should focus on economically disadvantaged young adults and those lower in conscientiousness. (shrink)

If a spinning sphere casts a shadow, does the shadow also spin? This riddle is the point of departure for an investigation into the nature of shadow movement. A general theory of motion will encompass all moving things, not just physical objects. Ultimately, I argue that round shadows do indeed spin. Shadows are followers of the objects that cast them. Parts of the shadow correspond to parts of the leader, so motion of the caster's parts accounts for motions of the (...) shadow's parts. I conclude with a discussion of how the dynamic aspects of shadows impose subtle constraints on other puzzles about shadows. (shrink)

We review the use of introspective and phenomenological methods in experimental settings. We distinguish different senses of introspection, and further distinguish phenomenological method from introspectionist approaches. Two ways of using phenomenology in experimental procedures are identified: first, the neurophenomenological method, proposed by Varela, involves the training of experimental subjects. This approach has been directly and productively incorporated into the protocol of experiments on perception. A second approach may have wider application and does not involve training experimental subjects in phenomenological method. (...) It requires front-loading phenomenological insights into experimental design. A number of experiments employing this approach are reviewed. We conclude with a discussion of the implications for both the cognitive sciences and phenomenology. (shrink)

Both individuals with diagnosed with Autism Spectrum Disorder and individuals high in psychopathic traits show reduced susceptibility to contagious yawning; that is, yawning after seeing or hearing another person yawn. Yet it is unclear whether the same underlying processes are responsible for the relationship between reduced contagion and these very different types of clinical traits. College Students watched videos of individuals yawning or scratching while their eye movements were tracked. They completed the Interpersonal Reactivity Index, the Autism-Spectrum Quotient, the Psychopathy (...) Personality Inventory-Revised, and the Adolescent and Adult Sensory Processing Disorder Checklist. Both psychopathic traits and autistic traits showed an inverse relationship to contagious yawning, consistent with previous research. However, the relationship between autistic traits and contagious yawning was moderated by eye gaze. Furthermore, participants high in autistic traits showed typical levels of contagious itching whereas adults high in psychopathic traits showed diminished itch contagion. Finally, only psychopathic traits were associated with lower overall levels of empathy. The findings imply that the underlying processes contributing to the disruptions in contagious yawning amongst individuals high in autistic vs. psychopathic traits are distinct. In contrast to adults high in psychopathic traits, diminished contagion may appear amongst people with high levels of autistic traits secondary to diminished attention to the faces of others, and in the absence of a background deficit in emotional empathy.

Sorensen here offers a unified solution to a large family of philosophical puzzles and paradoxes through a study of "blindspots": consistent propositions that cannot be rationally accepted by certain individuals even though they might by true.

Social studies of science and technology are dominated by action and macro approaches. This has led to a neglect of institutions and institutional arrangements at the meso level, which are important, in particular to the student of technology. The transfer of concepts and methods from social studies of science to technology studies has conserved this lack of concern with the meso level. This article suggests a more critical evaluation of this transfer, along with a review of the now popular assumption (...) of a high degree of similarity between science and technology. Two case studies show how meso-level considerations are important to an understanding of the nature of technological innovation and illustrate the lack of similarity between scientific and technological development.
