The importance of Georg Cantor’s religious convictions is often neglected in discussions of his mathematics and metaphysics. Herein I argue, pace Jan ́e (1995), that due to the importance of Christianity to Cantor, he would have never thought of absolutely infinite collections/inconsistent multiplicities,as being merely potential, or as being purely mathematical entities. I begin by considering and rejecting two arguments due to Ignacio Jan ́e based on letters to Hilbert and the generating principles for ordinals, respectively, showing that my reading (...) of Cantor is consistent with that evidence. I then argue that evidence from Cantor’s later writings shows that he was still very religious later in his career, and thus would not have given up on the reality of the absolute, as that would imply an imperfection on the part of God.

In Winter 2017, the first author piloted a course in formal logic in which we aimed to (a) improve student engagement and mastery of the content, and (b) reduce maths anxiety and its negative effects on student outcomes, by adopting student oriented teaching including peer instruction and classroom flipping techniques. The course implemented a partially flipped approach, and incorporated group-work and peer learning elements, while retaining some of the traditional lecture format. By doing this, a wide variety of student learning (...) preferences could be provided for. (shrink)

G. Genzten’s 1938 proof of the consistency of pure arithmetic was hailed as a success for finitism and constructivism, but his proof requires induction along ordinal notations in Cantor normal form up to the first epsilon number, ε0. This left the task of giving a finitisically acceptable proof of the well-ordering of those ordinal notations, without which Gentzen’s proof could hardly be seen as a success for finitism. In his seminal book Proof Theory G. Takeuti provides such a proof. After (...) a brief philosophical introduction, we provide a reconstruction of Takeuti’s proof including corrections, comments, re-organization and notational adjustments for the sake of clarity. The result is a much longer, but much more tractable proof of the well-ordering of ordinal notations in Cantor normal form less than ε0, that nevertheless follows Takeuti’s strategy closely. We end with some more general comments about that proof strategy and the notion of accessibility more generally. (shrink)

The question of the analyticity of Hume’s Principle (HP) is central to the neo-logicist project. We take on this question with respect to Frege’s definition of analyticity, which entails that a sentence cannot be analytic if it can be consistently denied within the sphere of a special science. We show that HP can be denied within non-standard analysis and argue that if HP is taken to depend on Frege’s definition of number, it isn’t analytic, and if HP is taken to (...) be primitive there is only a very narrow range of circumstances where it might be taken to be analytic. The latter discussion also sheds some light on the connections between the Bad Company and Caesar objections. (shrink)

If it could be shown that one of Gentzen's consistency proofs for pure number theory could be shown to be finitistically acceptable, an important part of Hilbert's program would be vindicated. This paper focuses on whether the transfinite induction on ordinal notations needed for Gentzen's second proof can be finitistically justified. In particular, the focus is on Takeuti's purportedly finitistically acceptable proof of the well-ordering of ordinal notations in Cantor normal form. The paper begins with a historically informed discussion of (...) finitism and its limits, before introducing Gentzen and Takeuti's respective proofs. The rest of the paper is dedicated to investigating the finitistic acceptability of Takeuti's proof, including a small but important fix to that proof. That discussion strongly suggests that there is a philosophically interesting finitist standpoint that Takeuti's proof, and therefore Gentzen's proof, conforms to. (shrink)

This volume contains thirteen papers that were presented at the 2017 Annual Meeting of the Canadian Society for History and Philosophy of Mathematics/Société canadienne d’histoire et de philosophie des mathématiques, which was held at Ryerson University in Toronto. It showcases rigorously reviewed modern scholarship on an interesting variety of topics in the history and philosophy of mathematics from Ancient Greece to the twentieth century. A series of chapters all set in the eighteenth century consider topics such as John Marsh’s techniques (...) for the computation of decimal fractions, Euler’s efforts to compute the surface area of scalene cones, a little-known work by John Playfair on the practical aspects of mathematics, and Monge’s use of descriptive geometry. After a brief stop in the nineteenth century to consider the culture of research mathematics in 1860s Prussia, the book moves into the twentieth century with an examination of the historical context within which the Axiom of Choice was developed and a paper discussing Anatoly Vlasov’s adaptation of the Boltzmann equation to ionized gases. The remaining chapters deal with the philosophy of twentieth-century mathematics through topics such as an historically informed discussion of finitism and its limits; a reexamination of Mary Leng’s defenses of mathematical fictionalism through an alternative, anti-realist approach to mathematics; and a look at the reasons that mathematicians select specific problems to pursue. Written by leading scholars in the field, these papers are accessible to not only mathematicians and students of the history and philosophy of mathematics, but also anyone with a general interest in mathematics.

Prior research on the influence of various ways of framing anthropogenic climate change do not account for the organized ACC denial in the U.S. media and popular culture, and thus may overestimate these frames' influence in the general public. We conducted an experiment to examine how Americans' ACC views are influenced by four promising frames for urging action on ACC —when these frames appear with an ACC denial counter-frame. This is the first direct test of how exposure to an ACC (...) denial message influences Americans' ACC views. Overall, these four positive frames have little to no effect on ACC beliefs. But exposure to an ACC denial counter-frame does significantly reduce respondents' belief in the reality of ACC, belief about the veracity of climate science, awareness of the consequences of ACC, and support for aggressively attempting to reduce our nation's GHG emissions in the near future. Furthermore, as expected by the Anti-Reflexivity Thesis, exposure to the ACC denial counter-frame has a disproportionate influence on the ACC views of conservatives, effectively activating conservatives' underlying propensity for anti-reflexivity.

Building on influential work in virtue ethics, this collection of essays examines the categories of self, person, and anthropology as foci for comparative analysis. The papers unite reflections on theory and method with descriptive work that addresses thinkers from the modern West, Christian and Jewish Late Antiquity, early China, and other settings. The introduction sets out central methodological issues that are subsequently taken up in each essay, including the origin of the categories through which comparison proceeds, the status of these (...) categories in the process of comparison, and the goals of comparison. In considering the question of goals, the introduction draws connections between comparative study and historical study within one tradition. Both types of analysis can bridge the gap between historical and normative work by attending to the ways in which the questions a scholar asks - not just the answers found - vary from one context to another.

This article proposes a formal model that integrates cognitive and psychodynamic psychotherapeutic models of psychopathy to show how two major psychopathic traits called lacks remorse and self-aggrandizing can be understood as a form of abnormal Bayesian inference about the self. This model draws on the predictive coding (i.e., active inference) framework, a neurobiologically plausible explanatory framework for message passing in the brain that is formalized in terms of hierarchical Bayesian inference. In summary, this model proposes that these two cardinal psychopathic (...) traits reflect entrenched maladaptive Bayesian inferences about the self, which defend against the experience of deep-seated, self-related negative emotions, specifically shame and worthlessness. Support for the model in extant research on the neurobiology of psychopathy and quantitative simulations are provided. Finally, we offer a preliminary overview of a novel treatment for psychopathy that rests on our Bayesian formulation. (shrink)

The publication of 'Animal Rights and Souls in the 18th Century' will be welcomed by everyone interested in the development of the modern animal liberation movement, as well as by those who simply want to savour the work of enlightenment thinkers pushing back the boundaries of both science and ethics. At last these long out-of-print texts are again available to be read and enjoyed - and what texts they are! Gems like Bougeant's witty reductio of the Christian view of animals (...) are included together with path-breaking works of ethics such as Primatt's A Dissertation on the Duty of Mercy and Sin of Cruelty to Brute Animals . There are works I have never seen before, including the remarkable Cry of Nature by the Scottish revolutionary Jacobin, John Oswald. In this set, everyone will find something novel, delightful and truly enlightening. - Peter Singer The discussion of animal rights and the moral status of animals, so prevalent in the late twentieth century, has its roots in the mid to late eighteenth century. Some of the themes we consider of recent invention - the legal standing of animals, the ethical status of vegetarians, cruelty towards animals, ultimately resulting in cruelty to humans - are of long standing. But in the eighteenth-century literature they are interconnected with theological issues surrounding animal souls, the birth of the life sciences, the great chain of being and other peculiarly eighteenth-century problems. This collection explores the exciting early discussions of moral theories concerning animals, placing them within their historical and social context. It reveals that issues such as vivisection, animal souls and vegetarianism were very much live philosophical subjects 200 years ago. The six volumes reprinted here includes complete works and edited extracts from such key eighteenth-century thinkers as Oswald, Primatt, Smellie, Monboddo and Jenyns. Many of the materials are extremely rare and never previously reprinted. The collection, edited with a new introduction and bio-bibliography by Aaron V. Garrett provides valuable original source material to supplement contemporary discussions of animal rights. --18th-century material on the theme of animal rights and practical ethics --an important supplement to contemporary animal rights discussions --provides a broader account of early discussions of the 'science of human nature' through animals --widens our understanding of 18th-century ethics through an important area of practical ethics --includes many scarce texts, most of which have never been reprinted before.

The 21st Century Cures Act is a major act of legislation that contains numerous changes to drug and device regulation. The House of Representatives passed the Act after considerable interest group lobbying, but the bill and the key changes made during its drafting remain controversial. Using publicly disclosed records of written comments on the bill, we reviewed the key areas of lobbying activity and the compromises made in the final text. We focused on legislative provisions relating to management of the (...) National Institutes of Health, incentives for medical product development, and approval standards for new drugs and devices. By the end of the first comment period, the Committee received 118 comments. Most respondents were patient organizations, professional societies, and pharmaceutical and device companies. Overall, the majority of public comments were positive, although public health and consumer organizations were underrepresented in the number of submitted comments. As the legislative process continued, the draft bill underwent several changes relating to NIH funding, market exclusivity provisions, and scrutiny of regulatory evidentiary standards. Understanding the key statutory provisions and how they have evolved could help patients, researchers, and advocates make more informed comments on the bill and future health care legislation.

This paper argues against the continued practice of Confucian familism, even in its moderate form, in East Asian hospitals. According to moderate familism, a physician acting in concert with the patient's family may withhold diagnostic information from the patient, and may give it to the patient's family members without her prior approval. There are two main approaches to defend moderate familism: one argues that it can uphold patient's autonomy and protect her best interests; the other appeals to cultural relativism by (...) construing the principle of ‘family autonomy’ to be incommensurable with that of individual autonomy. We respond to the first approach by explaining how the familist arguments either depend on some unreasonable assumptions or simply fail to articulate. The critique of the second approach is based on our recent survey showing that there is no dichotomy of relevant values between the East and the West: we believe that the result can effectively block the familist's reliance on certain traditional or cultural values to explain their resistance to the incorporation of pluralist values. Despite our disagreement with familism, we consider the Eastern emphasis on the family to be conducive to the communication between patient, family members and medical personnel, which is indispensible to the patient's well being and autonomy. We conclude that respect for patient autonomy is perfectly consistent with the involvement of the family in making medical decision as long as the family plays a merely consultant role. (shrink)

This chapter focuses on the ethical theories of the early modern philosophers Thomas Hobbes, Justus Lipsius, Descartes, Spinoza, Benjamin Whichcote, Lord Shaftesbury, and Samuel Clarke.

Arguably the biggest challenge in analyzing English tense is to account for the double access interpretation, which arises when a present tensed verb is embedded under a past attitude—e.g., "John said that Mary is pregnant". Present-under-past does not always result in a felicitous utterance, however—cf. "John believed that Mary is pregnant". While such oddity has been noted, the contrast has never been explained. In fact, English grammars and manuals generally prohibit present-under-past. Work on double access, on the other hand, has (...) either disregarded the oddity (e.g., Abusch 1997: 39) or treated it as a reflex of a particular dialect (e.g., Kratzer 1998: 14). The goal of the paper is to argue—based on a corpus study—that a present-under-past sentence is grammatical, but modulated by two, interacting pragmatic phenomena: cessation and parentheticality.

In the conclusion to this multi-part article I first review the discussions carried out around the six essential questions in psychiatric diagnosis – the position taken by Allen Frances on each question, the commentaries on the respective question along with Frances’ responses to the commentaries, and my own view of the multiple discussions. In this review I emphasize that the core question is the first – what is the nature of psychiatric illness – and that in some manner all further (...) questions follow from the first. Following this review I attempt to move the discussion forward, addressing the first question from the perspectives of natural kind analysis and complexity analysis. This reflection leads toward a view of psychiatric disorders – and future nosologies – as far more complex and uncertain than we have imagined. (shrink)

Thinking is a dynamic process resulting from practices of integration. Thought encounters in openness, wonder, receptivity, and contemplation confer upon us intellectual work that is uniquely our own. Digital patterns, however, distract us from these creative encounters. Our intellectual searching is weakened and fragmented by frenetic consumption of information. We miss out on reason's innate pull toward integration and concrete reality. This book is an invitation to enter into openness, wonder, receptivity, and contemplation with deeper understanding and intentionality. We can (...) do this by considering exemplars, persons who lived out the integrity of their hard-won beliefs, such as Thomas Merton, Eva Saulitis, Malcom X and St. Anselm. Each process of integration is applied also, so that practical knowledge and practice become a way into this intellectual restoration. We need deeper knowledge won in the slow orbit of encounters. Encounters in thought are precisely what each generation needs to apprehend the cosmos, nature, authority, truth, and moral action. Responsibility to this ecologic age requires a reform of reason; this book is just one attempt to convey a way toward this restoration. (shrink)

William Sharp Macleay developed the quinarian system of classification in his Horæ Entomologicæ, published in two parts in 1819 and 1821. For two decades, the quinarian system was widely discussed in Britain and influenced such naturalists as Charles Darwin, Richard Owen, and Thomas Huxley. This paper offers the first detailed account of Macleay’s development of the quinarian system. Macleay developed his system under the shaping influence of two pressures: (1) the insistence by followers of Linnaeus on developing artificial systems (...) at the expense of the natural system and (2) the apparent tension between the continuity of organic nature and the failure of linear classification schemes (which continuity seemed to require). Against what he perceived as dogmatic indolence on the part of the Linnaeans, Macleay developed a philosophy of science in which hypotheses that exceeded the available evidence should be proposed and subjected to severe tests. He also developed a novel comparative anatomical methodology, the method of variation, to aid in his search for the natural system. Using this method, he developed an intricate system that showed how organic nature could be continuous without being linear. A failure to appreciate these facets of Macleay’s thought has led to several misunderstandings of him and his work, most notably that he was an idealist. These misunderstandings are here rebutted.

In face of the multiple controversies surrounding the DSM process in general and the development of DSM-5 in particular, we have organized a discussion around what we consider six essential questions in further work on the DSM. The six questions involve: 1) the nature of a mental disorder; 2) the definition of mental disorder; 3) the issue of whether, in the current state of psychiatric science, DSM-5 should assume a cautious, conservative posture or an assertive, transformative posture; 4) the role (...) of pragmatic considerations in the construction of DSM-5; 5) the issue of utility of the DSM - whether DSM-III and IV have been designed more for clinicians or researchers, and how this conflict should be dealt with in the new manual; and 6) the possibility and advisability, given all the problems with DSM-III and IV, of designing a different diagnostic system. Part I of this article will take up the first two questions. With the first question, invited commentators express a range of opinion regarding the nature of psychiatric disorders, loosely divided into a realist position that the diagnostic categories represent real diseases that we can accurately name and know with our perceptual abilities, a middle, nominalist position that psychiatric disorders do exist in the real world but that our diagnostic categories are constructs that may or may not accurately represent the disorders out there, and finally a purely constructivist position that the diagnostic categories are simply constructs with no evidence of psychiatric disorders in the real world. The second question again offers a range of opinion as to how we should define a mental or psychiatric disorder, including the possibility that we should not try to formulate a definition. The general introduction, as well as the introductions and conclusions for the specific questions, are written by James Phillips, and the responses to commentaries are written by Allen Frances.

According to the standard analysis, humor theories can be classified into three neatly identifiable groups:incongruity, superiority, and relief theories. Incongruity theory is the leading approach and includes historical figures such as Immanuel Kant, Søren Kierkegaard, and perhaps has its origins in comments made by Aristotle in the Rhetoric. Primarily focusing on the object of humor, this school sees humor as a response to an incongruity, a term broadly used to include ambiguity, logical impossibility, irrelevance, and inappropriateness. The paradigmatic Superiority theorist (...) is Thomas Hobbes, who said that humor arises from a “sudden glory” felt when we recognize our supremacy over others. Plato and Aristotle are generally considered superiority theorists, who emphasize the aggressive feelings that fuel humor. The third group, Relief theory, is typically associated with Sigmund Freud and Herbert Spencer, who saw humor as fundamentally a way to release or save energy generated by repression. In addition, this article will explore a fourth group of theories of humor: play theory. Play theorists are not so much listing necessary conditions for something’s counting as humor, as they are asking us to look at humor as an extension of animal play. (shrink)

Compelling research in international relations and international political economy on global warming suggests that one part of any meaningful effort to radically reverse current trends of increasing green house gas (GHG) emissions is shared policies among states that generate costs for such emissions in many if not most of the world’s regions. Effectively employing such policies involves gaining much more extensive global commitments and developing much stronger compliance mechanism than those currently found in the Kyoto Protocol. In other words, global (...) warming raises the prospect that we need a global form of political authority that could coordinate the actions of states in order to address this environmental threat. This in turn suggests that any serious effort to mitigate climate change will entail new limits on the sovereignty of states. In this book I focus on the normative question of whether or not we have clear moral reasons to bind ourselves together in such a supranational form of political association. I argue that one can employ familiar liberal arguments for the moral legitimacy of political order at the state level to show that we do have a duty to support such a global political project. Even if one adopts the premises employed by the most influential forms of liberal scepticism to the ideas of global political and distributive justice, such as those advanced by John Rawls and Thomas Nagel, it is clear that the threat of global warming has expanded the scope of justice. We now have a global and demanding duty of justice to create the political conditions that would allow us to collectively address our impact on the Earth’s atmosphere. (shrink)

The concept of virtual practical knowledge is overlooked even by most “traditional” Thomists, and yet I have found that virtual practical knowledge is Thomas’s richest explanation of how God knows the possibles because it incorporates the principles that Thomas introduces in his general theory of divine knowledge.

My purpose is to examine how Kuhn and Polanyi might be mutually supportive and corrective so as to join forces in providing a more comprehensive understanding of the progress of science. My presentation will be divided into three parts: (I) The common ground Kuhn shares with Polanyi; (II) Four soft spots in Kuhn and their remedy; (III) Clarifying and upgrading Polanyi appeal to "objective reality.".

After commending Moleski for his excellent study, I focus attention on three areas that merit further clarification: (1) that Michael Polanyi’s quest for public recognition was legitimate and not the effect of a runaway vanity, (2) that Kuhn’s straining to define his dependence upon Polanyi was blocked by the unspecifiability clouding the discovery process and by his notion that Polanyi appealed to ESP to explain the dynamics of· discovery, and (3) that Kuhn’s success in gaining public recognition for his paradigm (...) shift was understandable. In the end, I list five areas wherein Kuhn’s account of scientific revolutions could be substantially improved by joining forces with Polanyi. (shrink)
