By the middle of the seventeenth century we that find that algebra is able to offer proofs in its own right. That is, by that time algebraic argument had achieved the status of proof. How did this transformation come about?

Brendan Larvor finds that the Archbishop of Canterbury's recent arguments about religious education are a curate's egg.

Peter Williams complains that Richard Dawkins wraps his naturalism in ‘a fake finery of counterfeit meaning and purpose’. For his part, Williams has wrapped his complaint in an unoriginal and inapt analogy. The weavers in Hans Christian Andersen's fable announce that the Emperor's clothes are invisible to stupid people; almost the whole population pretends to see them for fear of being thought stupid . Fear of being thought stupid does not seem to trouble Richard Dawkins. Moreover, Williams offers no reason (...) to think that such fear motivates any of Dawkins' readers. Perhaps all we are supposed to take from the fable is that Dawkins' naturalism is obviously lacking in meaning and purpose. If that is the intended reading, then by using this analogy, Williams has given himself an unnecessarily difficult task. Surely, it would be achievement enough for him to show that Dawkins' naturalism lacks meaning and purpose. There is no reason for Williams to make the extra claim that it obviously lacks meaning and purpose. After all, there is an obvious difficulty with arguing over several pages that something is obviously the case. (shrink)

Why is there Philosophy of Mathematics at all? Ian Hacking. in Metascience (2015).

The schism between analytic and continental philosophy resists repair because it is not confined to philosophers. It is a local manifestation of a far more profound and pervasive division. In 1959 C.P. Snow lamented the partition of intellectual life in to `two cultures': that of the scientist and that of the literary intellectual. If we follow the practice of most universities and bundle historical and literary studies together in the faculty of humanities on the one hand, and count pure mathematics (...) among the sciences on the other, then it is fair to say that the mutual ignorance and occasional hostility between scientists and humanists decried by Snow is still with us. And it runs through the middle of philosophy. Philosophy aspires to say something about everything, so it is unsurprising that philosophers have reproduced in miniature the division between the arts and the sciences. What is worrying is that we have failed to overcome it. (shrink)

Recent work in moral philosophy has emphasized the foundational role played by interpersonal accountability in the analysis of moral concepts such as moral right and wrong, moral obligation and duty, blameworthiness, and moral responsibility (Darwall 2006; 2013a; 2013b). Extending this framework to the field of moral psychology, we hypothesize that our moral attitudes, emotions, and motives are also best understood as based in accountability. Drawing on a large body of empirical evidence, we argue that the implicit aim of the central (...) moral motives and emotions is to hold people - whether oneself or others - accountable for compliance with the demands of morality. Moral condemnation is based in a motive to get perpetrators to hold themselves accountable for their wrongdoing, not, as is commonly supposed, a mere retributive motive to make perpetrators suffer (�2). And moral conscience is based in a genuine motive to hold oneself accountable for behaving in accordance with moral demands, not, as is commonly supposed, a mere egoistic motive to appear moral to others (�3). The accountability-based theory of the moral motives and emotions we offer provides better explanations of the extant empirical data than any of the major alternative theories of moral motivation. Moreover, conceiving of moral psychology in this way gives us a new and illuminating perspective on what makes morality distinctive: its essential connection to our practice of holding one another accountable (�4).

We pose two arguments for the view that sentences containing definite descriptions semantically express multiple propositions: a general proposition as Russell suggested, and a singular proposition featuring the individual who uniquely satisfies the description at the world-time of utterance. One argument mirrors David Kaplan's arguments that indexicals express singular propositions through a context-sensitive character. The second argument mirrors Kent Bach's and Stephen Neale's arguments for pluralist views about terms putatively triggering conventional implicatures, appositive, and nonrestrictive relative clauses. After presenting these (...) arguments, we show that rival explanations (appeals to implicature, referential use, presupposition, etc.) do not offer equally compelling explanations of the data, and defend the methodology employed in the arguments against some criticisms.

"Ethical Explorations: Moral Dilemmas in a Universe of Possibilities" by Brendan Shea is an open access textbook that provides a comprehensive study of ethical philosophy. Shea makes it his task to chart the sprawling landscape of moral thought from ancient times to the present, employing a straightforward, easily accessible style. -/- In the book, each chapter addresses a distinct ethical theory. Shea discusses everything from Plato's allegorical Cave to contemporary issues in bioethics. The text features relatable narratives, clear explanations (...) of core concepts, thought-provoking questions, and handy glossaries to help readers grasp the subject matter. -/- Among the topics, you'll find the principles of utilitarianism through the adventures of a princess, an exploration of duty via a story about a golem, and a look at natural law theory through an engaging science-fiction tale. Contemporary themes also make an appearance, including discussions on Marxism, Nietzsche's radical ideas, Simone de Beauvoir's intersection of feminism and existentialism, and racial theories from W.E.B. Du Bois and Martin Luther King. -/- As an open access (CC-BY) textbook, "Ethical Explorations" is freely available to everyone, making the study of moral philosophy accessible to all. It's a tool that gives its readers the means to wrestle with ethical questions in an ever-changing world. (shrink)

This paper argues that promises are proposals in joint practical deliberation, the activity of deciding together what to do. More precisely: to promise to ϕ is to propose (in a particular way) to decide together with your addressee(s) that you will ϕ. I defend this deliberative theory by showing that the activity of joint practical deliberation naturally gives rise to a speech act with exactly the same properties as promises. A certain kind of proposal to make a joint decision regarding (...) one's own actions turns out to have the very same normative effects, under the very same conditions, as a promise. I submit that this cannot be a coincidence: we should conclude that promises and the relevant kind of proposals in joint practical deliberation are one and the same. (shrink)

Gilbert Harman’s famous principle of Clutter Avoidance commands that “one should not clutter one’s mind with trivialities". Many epistemologists have been inclined to accept Harman’s principle, or something like it. This is significant because the principle appears to have robust implications for our overall picture of epistemic normativity. Jane Friedman (2018) has recently argued that one potential implication is that there are no genuine purely evidential norms on belief revision. In this paper, we present some new objections to a suitably (...) formulated version of the clutter principle qua norm on belief revision. Moreover, we argue that the clutter principle is best understood as a norm on non-doxastic stages of inquiry. In our view, it is a norm of asking and considering questions rather than a norm of settling on an answer to a question by forming a belief. (shrink)

In this paper, we contend that the psychology of addiction is similar to the psychology of ordinary, non-addictive temptation in important respects, and explore the ways in which these parallels can illuminate both addiction and ordinary action. The incentive salience account of addiction proposed by Robinson and Berridge (1993; 2001; 2008) entails that addictive desires are not in their nature different from many of the desires had by non-addicts; what is different is rather the way that addictive desires are acquired, (...) which in turn affects their strength. We examine these “incentive salience” desires, both in addicts and non-addicts, contrasting them with more cognitive desires. On this account, the self-control challenge faced by addicted agents is not different in kind from that faced by non-addicted agents – though the two may, of course, differ greatly in degree of difficulty. We explore a general model of self-control for both the addict and the non-addict, stressing that self-control may be employed at three different stages, and examining the ways in which it might be strengthened. This helps elucidate a general model of intentional action. (shrink)

In this thesis, I give a metascientific account of causality in medicine. I begin with two historical cases of causal discovery. These are the discovery of the causation of Burkitt’s lymphoma by the Epstein-Barr virus, and of the various viral causes suggested for cervical cancer. These historical cases then support a philosophical discussion of causality in medicine. This begins with an introduction to the Russo- Williamson thesis (RWT), and discussion of a range of counter-arguments against it. Despite these, I argue (...) that the RWT is historically workable, given a small number of modifications. I then expand Russo and Williamson’s account. I first develop their suggestion that causal relationships in medicine require some kind of evidence of mechanism. I begin with a number of accounts of mechanisms and produce a range of consensus features of them. I then develop this consensus position by reference to the two historical case studies with an eye to their operational competence. In particular, I suggest that it is mechanistic models and their representations which we are concerned with in medicine, rather than the mechanism as it exists in the world. -/- I then employ these mechanistic models to give an account of the sorts of evidence used in formulating and evaluating causal claims. Again, I use the two human viral oncogenesis cases to give this account. I characterise and distinguish evidence of mechanism from evidence of difference-making, and relate this to mechanistic models. I then suggest the relationship between types of evidence presents us with a means of tackling the reference-class problem. This sets the scene for the final chapter. Here, I suggest the manner in which these two different classes of evidence become integrated is also reflected in the way that developing research programmes change as their associated causal claims develop.

In its original form, Nozick’s experience machine serves as a potent counterexample to a simplistic form of hedonism. The pleasurable life offered by the experience machine, its seems safe to say, lacks the requisite depth that many of us find necessary to lead a genuinely worthwhile life. Among other things, the experience machine offers no opportunities to establish meaningful relationships, or to engage in long-term artistic, intellectual, or political projects that survive one’s death. This intuitive objection finds some support in (...) recent research regarding the psychological effects of phenomena such as video games or social media use. After a brief discussion of these problems, I will consider a variation of the experience machine in which many of these deficits are remedied. In particular, I’ll explore the consequences of a creating a virtual world populated with strongly intelligent AIs with whom users could interact, and that could be engineered to survive the user’s death. The presence of these agents would allow for the cultivation of morally significant relationships, and the world’s long-term persistence would help ground possibilities for a meaningful, purposeful life in a way that Nozick’s original experience machine could not. While the creation of such a world is obviously beyond the scope of current technology, it represents a natural extension of the existing virtual worlds provided by current video games, and it provides a plausible “ideal case” toward which future virtual worlds will move. While this improved experience machine would seem to represent progress over Nozick’s original, I will argue that it raises a number of new problems stemming from the fact that that the world was created to provide a maximally satisfying and meaningful life for the intended user. This, in turn, raises problems analogous in some ways to the problem(s) of evil faced by theists. In particular, I will suggest that it is precisely those features that would make a world most attractive to potential users—the fact that the AIs are genuinely moral agents whose well-being the user can significantly impact—that render its creation morally problematic, since they require that the AIs inhabiting the world be subject to unnecessary suffering. I will survey the main lines of response to the traditional problem of evil, and will argue that they are irrelevant to this modified case. I will close by considering by consider what constraints on the future creation of virtual worlds, if any, might serve to allay the concerns identified in the previous discussion. I will argue that, insofar as the creation of such worlds would allow us to meet morally valuable purposes that could not be easily met otherwise, we would be unwise to prohibit it altogether. However, if our processes of creation are to be justified, they must take account of the interests of the moral agents that would come to exist as the result of our world creation. (shrink)

In this reflection I draw out Richard J. Bernstein’s claim that he was a ‘scavenger’ and put it to use in revisiting main themes of his engagements with pragmatism, hermeneutics, Hegel, and critical theory. This piece is included in a memorial issue of Dewey Studies on Bernstein.

In this article, I begin by giving a brief history of melanoma causation. I then discuss the current manner in which malignant melanoma is classified. In general, these systems of classification do not take account of the manner of tumour causation. Instead, they are based on phenomenological features of the tumour, such as size, spread, and morphology. I go on to suggest that misclassification of melanoma is a major problem in clinical practice. I therefore outline an alternative means of classifying (...) these tumours based on causal factors. By analogy with similar systems that have recently emerged for other cancers, I suggest that this causal classification is likely to be both workable and helpful, even in the absence of a full causal-mechanistic understanding of the aetiology of the tumour.

Karl Popper (1902-1994) was one of the most influential philosophers of science of the 20th century. He made significant contributions to debates concerning general scientific methodology and theory choice, the demarcation of science from non-science, the nature of probability and quantum mechanics, and the methodology of the social sciences. His work is notable for its wide influence both within the philosophy of science, within science itself, and within a broader social context. Popper’s early work attempts to solve the problem of (...) demarcation and offer a clear criterion that distinguishes scientific theories from metaphysical or mythological claims. Popper’s falsificationist methodology holds that scientific theories are characterized by entailing predictions that future observations might reveal to be false. When theories are falsified by such observations, scientists can respond by revising the theory, or by rejecting the theory in favor of a rival or by maintaining the theory as is and changing an auxiliary hypothesis. In either case, however, this process must aim at the production of new, falsifiable predictions. While Popper recognizes that scientists can and do hold onto theories in the face of failed predictions when there are no predictively superior rivals to turn to. He holds that scientific practice is characterized by its continual effort to test theories against experience and make revisions based on the outcomes of these tests. By contrast, theories that are permanently immunized from falsification by the introduction of untestable ad hoc hypotheses can no longer be classified as scientific. Among other things, Popper argues that his falsificationist proposal allows for a solution of the problem of induction, since inductive reasoning plays no role in his account of theory choice. Along with his general proposals regarding falsification and scientific methodology, Popper is notable for his work on probability and quantum mechanics and on the methodology of the social sciences. Popper defends a propensity theory of probability, according to which probabilities are interpreted as objective, mind-independent properties of experimental setups. Popper then uses this theory to provide a realist interpretation of quantum mechanics, though its applicability goes beyond this specific case. With respect to the social sciences, Popper argued against the historicist attempt to formulate universal laws covering the whole of human history and instead argued in favor of methodological individualism and situational logic.

Cornell realists maintain that irreducible moral properties have earned a place in our ontology in virtue of the indispensable role they play in a variety of explanations. These explanations can be divided into two groups: those that employ thin ethical concepts and those that employ thick ethical concepts. Recent work on thick concepts suggests that they are not inherently evaluative in their meaning. If correct, this creates problems for the moral explanations of Cornell realists, since the most persuasive moral explanations (...) are those that employ thick concepts. If thick concepts are not inherently evaluative, then the most plausible explanations on offer cannot support Cornell realism. Moral explanations employing thin concepts, however, are too flimsy to support the view. Unless proponents can develop a compelling story about thick concepts or thin explanations, Cornell realism is in trouble. (shrink)

Fictional realists hold that fictional characters are real entities. However, Anthony Everett [“Against Fictional Realism”, Journal of Philosophy (2005)] notes that some fictions leave it indeterminate whether character A is identical to character B, while other fictions depict A as simultaneously identical and distinct from B. Everett argues that these fictions commit the realist to indeterminate and impossible identity relations among actual entities, and that as such realism is untenable. This paper defends fictional realism: for fictions depicting non-classical identity between (...) A and B, the realist should hold that there are two salient fragments, one with a single character (named both ‘A’ and ‘B’) and the other with two (named ‘A’ and ‘B’, respectively). Truth according to the fiction depicting indeterminate identity is determined by supervaluating over truth according to those salient fragments. For fictions depicting impossible identity, truth is determined by subvaluating over truth according to those two salient fragments. (shrink)

Political conspiracy theories—e.g., unsupported beliefs about the nefarious machinations of one’s cunning, powerful, and evil opponents—are adopted enthusiastically by a great many people of widely varying political orientations. In many cases, these theories posit that there exists a small group of individuals who have intentionally but secretly acted to cause economic problems, political strife, and even natural disasters. This group is often held to exist “in the shadows,” either because its membership is unknown, or because “the real nature” of its (...) members’ allegiances, motives, and methods has been concealed from the public at large. Paradigmatic examples of these political conspiracy theories include anti-Semitic beliefs of the sort associated with The Protocols of the Elder of Zion, the “Red Scare” of the 1950s, claims about the “New World Order,” and many others. -/- Why do these theories attract so many adherents? In this essay, I’ll attempt to spread some light on this issue by applying Kahneman and Tversky’s highly influential work on reasoning under uncertainty. I’ll proceed by first providing a brief introduction to Kahneman and Tversky’s work on reasoning under uncertainty, and the way in which this relates to standard economic and philosophic accounts of rational behavior, as well as philosophical ideas about the role of intuition. Next, I’ll move onto some specific interconnected aspects of this work that are relevant to understanding conspiracy theories, including errors involving probabilistic reasoning (“Prospect Theory”), those involving the inappropriate use of heuristics, and those related to the “framing” of certain outcomes as losses from a baseline. This essay will conclude by making two related points. First, some of the most important reasoning errors committed by adherents of conspiracy theories are errors that many of us regularly commit. Given that self-awareness of these errors provides only minimal protection from committing them, this suggests that many of use may be more vulnerable to conspiratorial reasoning than we may like to believe. Second, in the light of this danger, I will outline a few steps that might be taken to help inoculate ourselves against the appeal of these theories, and to help respond to the conspiratorial arguments of others.

Over the course of the Twilight series, Bella strives to and eventually succeeds in convincing Edward to turn her into a vampire. Her stated reason for this is that it will allow her to be with Edward forever. In this essay, I consider whether this type of immortality is something that would be good for Bella, or indeed for any of us. I begin by suggesting that Bella's own viewpoint is consonant with that of Leo Tolstoy, who contends that one (...) could not have meaningful life without immortality, because only immortality could allow one to make a permanent difference in the world. I argue that this characterization of a meaningful life is problematic, however, insofar as (1) immortality is neither sufficient nor necessary for having such an impact and (2) there is little reason to think that having such an impact is constitutive of a meaningful life. I go on to consider Edward's fear that vampires lack a soul as it relates to Martha Nussbaum's claim that immortal beings would be less capable of certain paradigmatic human values and virtues such as courage, love, or self-sacrifice. I suggest, contra Nussbaum, that Carlisle provides an example of an immortal who displays recognizably human virtues. However, the possibility of Carlisle's being virtuous in this way depends on the existence of other creatures who are mortal. -/- I close by considering the problem of boredom, as articulated by Bernard Williams. According to Williams, a meaningful human life is constituted by certain categorical desires such as the desire to raise children or to create art. The projects aimed at accomplishing these desires are necessarily finite in length, and cannot be repeated indefinitely without losing their value. I argue that many, though perhaps not all, of the immortals described in the series suffer from such boredom. For example, Edward and Rosalie struggle to find meaning in their lives and most werewolves choose to age and die normally after a certain time. Perhaps more significantly, many of the non-"vegetarian" vampires seem to have become entirely divorced from any recognizably human projects or values, and have become focused entirely on satisfying their immediate desires. These examples provide some reason to think that many of Bella's reasons for living, which are essentially tied to her mortality, are not likely to be met by becoming immortal. While this does not show that her choice to become a vampire will leave her ultimately unhappy, it does suggest that her doing so represents a considerable sacrifice. (shrink)

Disney’s Frozen (2013) and Frozen 2 (2019) are among the highest-grossing films of all time (IMDb 2021) and are arguably among the most influential works of fantasy produced in the last decade in any medium. The films, based loosely on Hans Christensen Andersen’s “The Snow Queen” (Andersen 2014) focus on the adventures of the sisters Anna and Elsa as they, together with their companions, seek to safeguard their people both from external threats and (importantly) from Elsa’s inabilities to control her (...) magical abilities to summon ice and snow. While Anna’s choices drive much of the action of both films, Elsa has undoubtedly been the more influential and popular of the two characters, as indicated by measures such as merchandise sales (Ellen Byron and Paul Ziobro 2014), Google search data (Play Like Mum 2020), and even baby name choices (Wolfers 2015). -/- Despite her popularity, Elsa is in many ways a paradoxical sort of hero, as she finds her actions all but predetermined by both external and internal forces. This is particularly the case in the first film, where we meet an Elsa who has been born with a power she cannot control, and which appears more as a force of nature than as anything that “belongs” to Elsa. The film’s action is driven, in large part, precisely by Elsa’s failures to exert control over her emotions and abilities. She begins the film by accidentally injuring Anna. This, in turn, causes Elsa to become fearful and withdrawn and to isolate herself from her sister, even after their parents die on a quest to find a cure for Elsa. Elsa's fear and lack of control lead to an even more dire outcome when she inadvertently calls down winter on Arendelle and abandons her people for the mountains. It is only through Anna's devoted quest to rescue her sister, first by pursuing her to the mountains, and later by throwing herself in front of the villainous Hans’ sword attack on her sister, that Elsa (and Arendelle) are saved. Elsa's most active contribution to this is to appreciate the import of Anna's sacrifice and to discover the power of "love" to overcome her fear. -/- What then, are we to make of Elsa as a character? It is the younger sister Anna who corresponds most closely to Gerda, the unquestioned protagonist of Andersen’s original tale, and her character arc fits neatly with the well-known “Hero’s Journey” model for describing myth (Campbell 2020). It is Anna, for example, who goes on a quest, meets a group of motley companions (the human Kristoff, the reindeer Sven, and the magical snowman Olaf), accepts advice from wise elders (the trolls), undergoes a severe trial, and even gets the "reward" of romantic love at the end. All of this has led some scholars (Niemiec and Bretherton 2015; Heit 2019) to hold up Anna, rather than Elsa, as something like the hero of the story. Existing scholarship on Elsa, by contrast, has focused largely on issues related to her gender and sexuality (Law 2014; Lee 2015; Steinhoff 2017; Streiff and Dundes 2017; Dundes, Streiff, and Streiff 2018; Dundes 2020; Llompart and Brugué 2020). In what follows, I’ll be taking a closer look at Elsa’s unique status as a protagonist, and what her struggles with fate reveal about the nature of free will and ethical responsibility. I’ll argue that Elsa provides a useful model of a “Stoic hero” and that her strengths and weaknesses as a character provide valuable insight into an often-misunderstood school of philosophy. My argument will proceed in several stages. I’ll begin by describing the basic tenets of Stoic philosophy, paying special attention to the role of fate and nature. I’ll then move on to a more detailed treatment of Stoic ethics, as exemplified by Elsa’s own character development. I’ll close by considering the infamous “Lazy Argument” against. (shrink)

Dr. Strange sees Dr. Stephen Strange abandon his once-promising medical career to become a superhero with the ability to warp time and space, and to travel through various dimensions. In order to make this transition, he is required to abandon many of his previous assumptions about the way the world works and learn to see things in a new way. Importantly, this is not merely a matter of learning a few facts, or of mastering new techniques. Instead, Dr. Strange is (...) required to alter his conception of the basic nature of the world and of how he relates to it. In time, this change extends to his values as well, as Strange comes to embrace his role in safeguarding the human world from interdimensional threats. -/- It is tempting to interpret Dr. Strange’s experience as one that shows the limits of rational, scientific inquiry, or even of human knowledge more generally. However, in this essay, I’d like to explore a different interpretation: that Strange’s experience can most fruitfully be thought of as a scientific revolution, in which Strange moves from one way of carrying out scientific inquiry to a different, incompatible way of doing it. In order to do this, I’ll be exploring the work of philosopher and historian of science Thomas Kuhn, who wrote a book—The Structure of Scientific Revolutions--about just this topic. Among other things, Kuhn’s work introduced the highly useful (though commonly misunderstood) notion of a paradigm shift. -/- We’ll begin by exploring what Kuhn describes as normal science, which consists of applying a set of well-understood concepts and methods to problems of interest. This “puzzle-solving” aspect of science is exemplified by Strange’s early successes in medicine. During this stage, scientists have good reasons to avoid questioning the basic validity of their paradigm, and to instead blame any problems that arise on other factors, such as human error. (As fans will know, Strange is quite good at assigning blame in just this way.) A crisis only occurs when significant, serious anomalies have accrued, such as those that Strange encounters in the aftermath of his accident. Even then, however, the old paradigm will only be abandoned only if a new paradigm can be found. Again, Strange’s experience bears this out, as he is able to move on only when the Sorcerer Supreme introduces him to the Mystic Arts. -/- Along the way, we’ll consider what it means for a practice to count as a scientific paradigm, and why it’s not just “anything goes.” Among other things, a paradigm requires that practitioners agree on which problems are most important, which techniques are appropriate to which problems, and what exemplary models of successful work look like. The Mystic Arts of Strange’s world, unlike the pseudoscientific theories of our own, plausibly do quite well on these sorts of criteria. (shrink)

Competitive quiz shows, and Jeopardy! in particular, occupy a unique place among TV game shows. The most successful Jeopardy! contestants—Ken Jennings, Brad Rutter, Frank Sparenberg, and so on—have appeared on late night talk shows, been given book contracts, and been interviewed by major newspapers. This sort of treatment is substantially different than, say, the treatment that the winners of The Price is Right or Deal or No Deal are afforded. The distinctive status of quiz shows is evidenced in other ways (...) as well; for instance, consider the widespread public outrage that accompanied the discovery of fixed quiz shows in the 1950s of the fact that, when IBM wanted to find a task to test the latest developments of artificial intelligence, they chose the game of Jeopardy. In this essay, I’ll take a look at Jeopardy! as an exemplar of a certain sort of game, and will suggest that part of what gives Jeopardy! its distinctive status is that it is a qualitatively good game—that is, it is a game that that fulfills just those functions a game is supposed to fulfill. I’ll begin by showing how Jeopardy! meets Bernard Suits’ (1967, 1988, 2005) definition of games, according to which games are characterized as activities that have certain sorts of rules and in which participants are required to have the right attitude toward these rules. Among other things, I’ll talk about the role played by some of Jeopardy’s distinctive rules (“remember to phrase your answer in the form of a question”) and about the possible differences a monetary reward makes to game players’ attitudes. I’ll then go on to talk about what distinguishes Jeopardy! from other, superficially similar sorts of games. I’ll concentrate on three factors in particular: (1) the fact that the skills required by Jeopardy! have value outside of the game, (2) the fact that observers in Jeopardy! can “play along” with the contestants on TV, and (3) the fact that success in the game is determined, to a very great extent, by the skills of the participant and not by other facts (such as luck). To close, I’ll talk more generally about the distinction between good games and not-so-good games, and will discuss why it is that good games are worth taking seriously. In this section, I’ll discuss some recent work on the value of games and sports, and will make some suggestions about how these accounts might be tailored to account for the specific virtues of a game like Jeopardy.

In this paper, I offer one example of conceptual change. Specifically, I contend that the discovery that viruses could cause cancer represents an excellent example of branch jumping, one of Thagard’s nine forms of conceptual change. Prior to about 1960, cancer was generally regarded as a degenerative, chronic, non-infectious disease. Cancer causation was therefore usually held to be a gradual process of accumulating cellular damage, caused by relatively non-specific component causes, acting over long periods of time. Viral infections, on the (...) other hand, were generally understood to be acute processes, whereby single, specific and necessary causal agents acted alone to produce disease. However, during the 1960s and 1970s, a number of cancers were discovered to have an infectious aetiology. Of particular note were two—Burkitt’s lymphoma and cervical cancer—which I will discuss in detail later in this piece. Together, these discoveries led, in the short term, to a tentative aetiological reclassification of some types of cancer as infectious diseases and, in the longer term, to a full-blown reclassification of cancer as an aetiological disease branch in its own right. This process of reclassification forms the empirical basis for my concluding remarks on the influence of classification upon causation in medicine. Through this, I aim to demonstrate that conceptual change, far from being a purely abstract concern of the philosopher of science, is of substantial import to scientific practitioners. (shrink)

This is the text of a paper (along with appendixes) delivered at the 2019 annual meeting of the Minnesota Philosophical Society on Oct 26 in Cambridge, MN. -/- Beauchamp and Childress’s “Four Principles” (or “Principlism”) approach to bioethics has become something of a standard not only in bioethics classrooms and journals, but also within medicine itself. In this teaching-focused workshop, I’ll be doing the following: (1) Introducing the basics of the “Four Principles” approach, with a special focus on its relation (...) to the common morality and the importance to weighing and balancing of competing norms. (2) Comparing and contrasting this to other potential approaches, such as those provided by virtue ethics, act utilitarianism, casuistry, and competing versions of principles-based ethics. (3) Considering the ways in which the principles-based approach can best be implemented for lower-level, introductory bioethics classes, where the average student may have little background knowledge in either philosophy or medicine. I’ll be presenting sample activities, case studies, and lesson plans. There will be considerable time reserved for discussion at the end, so that participants can exchange ideas relating to the teaching of both bioethics and other varieties of applied ethics. (shrink)

Over the course of its six seasons, the Netflix show the House of Cards (HOC) details the rise to power of Claire and Frank Underwood in a fictional United States. They achieve power not by winning free and fair elections, but by exploiting various weaknesses of the U.S. political system. Could such a thing happen to our own democracies? This chapter argues that it is a threat that should be taken seriously, as the structure of HOC’s democratic institutions closely mirrors (...) our own, and the flaws that the Underwoods exploit are precisely those that have allowed autocrats to capture democracies “from the inside.” Of even greater concern, these flaws may flow from the nature of democracy itself. This possibility is explored by considering the events of the HOC in the light of the anti-democratic arguments of Plato and Hobbes. The chapter concludes by briefly considering responses to these arguments. (shrink)

I argue that there are at least two concepts of law of nature worthy of philosophical interest: strong law and weak law. Strong laws are the laws investigated by fundamental physics, while weak laws feature prominently in the “special sciences” and in a variety of non-scientific contexts. In the first section, I clarify my methodology, which has to do with arguing about concepts. In the next section, I offer a detailed description of strong laws, which I claim satisfy four criteria: (...) (1) If it is a strong law that L then it also true that L; (2) strong laws would continue to be true, were the world to be different in some physically possible way; (3) strong laws do not depend on context or human interest; (4) strong laws feature in scientific explanations but cannot be scientifically explained. I then spell out some philosophical consequences: (1) is incompatible with Cartwright’s contention that “laws lie” (2) with Lewis’s “best-system” account of laws, and (3) with contextualism about laws. In the final section, I argue that weak laws are distinguished by (approximately) meeting some but not all of these criteria. I provide a preliminary account of the scientific value of weak laws, and argue that they cannot plausibly be understood as ceteris paribus laws. (shrink)

In this article, I use science-fiction scenarios drawn from Dan Simmons’ “Hyperion Cantos” (Hyperion, The Fall of Hyperion, Endymion, The Rise of Endymion) to explore a cluster of issues related to the evolutionary history and neural bases of human moral cognition, and the moral desirability of improving our ability to make moral decisions by techniques of neuroengineering. I begin by sketching a picture of what recent research can teach us about the character of human moral psychology, with a particular emphasis (...) on highlighting the importance of our evolutionary background as social mammals. I then consider how the moral psychology of intelligent machines might differ from our own, and argue that the differences would depend on the extent to which their evolutionary background resembled our own. I offer two very different case studies—the “Technocore AIs” that have evolved from early, parasitic computer programs, and the mysterious “Shrike,” who travels backward through time. I close by looking at the character of Aenea, a messianic figure that is a joint descendant of humans and machines. I argue that while the sort of “moral enhancement” she represents is far beyond the scope of either contemporary neuroscience or artificial intelligence research, it nevertheless represents a worthwhile goal.

Roberto Frega’s Pragmatism and the Wide View of Democracy reformulates the question of democracy posed by our current historic conjuncture using the resources of a variety of pragmatic thinkers. He brings into the contemporary conversation regarding democracy’s fortunes both classical and somewhat neglected figures in the pragmatic tradition to deal with questions of power, ontology, and politics. In particular, Frega takes a social philosophical starting point and draws out the consequences of this fundamental shift in approach to questions of democratic (...) and political theory. This turn to social philosophy as a theoretically more sufficient conceptual vocabulary, extended in detail by Frega, raises questions regarding the work that a social ontology does in clarifying the role of economic and political approaches to democracy that are worth further exploration. Likewise, the practical proposals for moving beyond methodological nationalism with respect to forming publics for the sake of problem-solving, while providing a clarifying and fresh starting point, are still too beholden to models of agency and expressions of coordinated action that themselves are the very fruit of those systems which undermine democratic power in the first instance.

Alice encounters at least three distinct problems in her struggles to understand and navigate Wonderland. The first arises when she attempts to predict what will happen in Wonderland based on what she has experienced outside of Wonderland. In many cases, this proves difficult -- she fails to predict that babies might turn into pigs, that a grin could survive without a cat or that playing cards could hold criminal trials. Alice's second problem involves her efforts to figure out the basic (...) nature of Wonderland. So, for example, there is nothing Alice could observe that would allow her to prove whether Wonderland is simply a dream. The final problem is manifested by Alice's attempts to understand what the various residents of Wonderland mean when they speak to her. In Wonderland, "mock turtles" are real creatures and people go places with a "porpoise" (and not a purpose). All three of these problems concern Alice's attempts to infer information about unobserved events or objects from those she has observed. In philosophical terms, they all involve *induction*. -/- In this essay, I will show how Alice's experiences can be used to clarify the relation between three more general problems related to induction. The first problem, which concerns our justification for beliefs about the future, is an instance of David Hume's classic *problem of induction*. Most of us believe that rabbits will not start talking tomorrow -- the problem of induction challenges us to justify this belief. Even if we manage to solve Hume's puzzle, however, we are left with what W.V.O. Quine calls the problems of *underdetermination *and *indeterminacy.* The former problem asks us to explain how we can determine *what the world is really like *based on *everything that could be observed about the world. *So, for example, it seems plausible that nothing that Alice could observe would allow her to determine whether eating mushrooms causes her to grow or the rest of the world to shrink. The latter problem, which might remain even if resolve the first two, casts doubt on our capacity to determine *what a certain person means *based on *which words that person uses.* This problem is epitomized in the Queen's interpretation of the Knave's letter. The obstacles that Alice faces in getting around Wonderland are thus, in an important sense, the same types of obstacles we face in our own attempts to understand the world. Her successes and failures should therefore be of real interest. (shrink)

The early modern period (roughly, 1600–1800 ce) in Europe brought tremendous changes in intellectual, political, and cultural life. It was a period in which philosophical debates were inevitably bound up with questions about the nature and sources of religious truth. A chronological examination of some of the period’s major thinkers highlights two issues that were central to the development of philosophy of religion in the period. The first concerns the relations between God, the soul, and the body; the other concerns (...) the relationship between human reason and divine revelation. (shrink)

As any fan of Leonard Cohen will tell you, many of his songs are deeply “philosophical,” in the sense that they deal reflectively and intelligently with the many of the basic issues of everyday human life, such as death, sex, love, God, and the meaning of life. It may surprise these same listeners to discover that much of academic philosophy (both past and present) has relatively little in common with this sort of introspective reflection, but is instead highly abstract, methodologically (...) complex, and filled with technical terminology that can make it inaccessible to anyone except specialists. This is not true of all philosophy, however, and Cohen’s focus on the immediate problems facing ordinary humans has much in common with the theories and ideas proposed by the Hellenistic philosophers who dominated the intellectual life of Greek- and Roman-influenced Europe for almost a thousand years. In this essay, I’ll use Cohen’s songs to examine the three major branches of Hellenistic thought: Stoicism (That’s No Way to Say Goodbye, If It Be Your Will), Epicureanism (Everybody Knows, Closing Time), and Skepticism (Famous Blue Raincoat, Different Sides).

The methodological foundations of any scientific discipline are shaped by the goals towards which that discipline is aiming. While it is almost universally accepted that the goals of explanation and prediction of natural and non-human phenomena have been met with great success since the scientific revolution, it is almost just as universally accepted that the social sciences have not even come close to achieving these goals. This raises the question addressed in this paper, namely, what is economics, and social science (...) more broadly speaking, for? What is their aim, and how is it similar and dissimilar to that of the natural sciences as we have come to classify them? I take up this question from a pragmatic perspective in this paper, setting economics within the wider context of social inquiry. Specifically, I turn to Hilary Putnam and John Dewey as exemplars of the pragmatic critique of any economics that sees its goals in line with those of the natural sciences, that is, as aiming for explanation and prediction according to governing laws of human behaviour. NB: this is a preprint that underwent some minor edits. (shrink)

In this essay, I critically examine the ways in which the characters of Alias attempt to balance their impartial moral obligations (e.g. duties toward humanity) and their personal obligations (e.g. duties toward one's children). I specifically examine three areas of conflict: (1) choices between saving loved ones and maximizing consequences, (2) choices to maintain or sever relationships with characters who are vicious or immoral, and (3) choices to seek or not seek revenge on the behalf of loved ones. I conclude (...) that Sydney's and Jack's moral choices show that one can and should privilege loved ones to some extent, but that this privilege has limits. (shrink)

Miracle Max, it seems, is the only remaining miracle worker in all of Florin. Among other things, this means that he (unlike anyone else) can resurrect the recently dead, at least in certain circumstances. Max’s peculiar talents come with significant perks (for example, he can basically set his own prices!), but they also raise a number of ethical dilemmas that range from the merely amusing to the truly perplexing: -/- How much about Max’s “methods” does he need to reveal to (...) his patients? Is it really OK for Max to lie about Valerie’s being a witch, even though she really isn’t? Just how much of the “truth” does Max have to tell his patients? -/- Let’s suppose that Humperdinck had offered Max his old job back. Would it have been OK for Max to accept this offer? What about if Humperdinck wanted him to do experiments at “the Zoo”? -/- Is Max obligated to offer his services to everyone who needs them, such as the (mostly) dead Westley and friends? Or is he free to pick and choose? -/- In this chapter, I’ll consider how these questions might be addressed using concepts of medical ethics. As it turns out, Max’s dilemmas are not too different from the sorts of dilemmas that many medical professionals encounter in their daily lives, and exploring how Max could (or should) respond to them can help us figure out what we can do here in the “real” world.

What is the relation between moral reasons and moral requirement? Specifically: what relation does an action have to bear to one’s moral reasons in order to count as morally required? This paper defends the following answer to this question: an action is morally required just in case the moral reasons in favor of that action are enough on their own to outweigh all of the reasons, moral and nonmoral, to perform any alternative. I argue that this decisive moral reason view (...) satisfies three key desiderata: it is compatible with either affirming or denying the existence of moral options; it vindicates moral rationalism, the thesis that an action can be morally required only if one ought to do it all things considered; and most distinctively, it explains why unexcused moral wrongdoing necessarily shows disregard for moral reasons.

Over the past 50 years, there has been a great deal of philosophical interest in laws of nature, perhaps because of the essential role that laws play in the formulation of, and proposed solutions to, a number of perennial philosophical problems. For example, many have thought that a satisfactory account of laws could be used to resolve thorny issues concerning explanation, causation, free-will, probability, and counterfactual truth. Moreover, interest in laws of nature is not constrained to metaphysics or philosophy of (...) science; claims about laws play essential roles in areas as diverse as the philosophy of religion (e.g., in the argument from design) and the philosophy of mind (e.g., in the formulation of Davidson’s anomalous monism). In my dissertation, I consider and reject the widely-held thesis that the facts concerning laws can be reduced to the facts concerning the particular entities that the laws “govern,” and that the laws thus have no independent existence. I instead defend a version of nomic primitivism, according to which the facts about laws cannot be reduced to facts that are themselves non-nomic – i.e., to facts that do not fundamentally involve laws, counterfactuals, causes, etc. Insofar as the truth or falsity of reductionism about laws has implications for many of the problems mentioned above, I think that this result should be of interest even to those who who do not work in metaphysics or the philosophy of science. My methodology, which I lay out and defend in Chapter One, is a version of Carnapian explication. This method emphasizes the importance of articulating and maintaining clear distinctions between (1) the vague concept (or concepts) law of nature inherent in ordinary language and scientific practice and (2) the precise analyses of “law of nature” that philosophers have proposed as potential replacements for this concept. I argue that metaphysics-as-explication has clear advantages over rival conceptions of metaphysical methodology; in particular, it allows us to formulate evaluative criteria for metaphysical claims. In Chapter Two, I offer an example of how careful attention to concepts already in use can help resolve philosophical debate. Specifically, I argue that much recent literature has mistakenly assumed that there is only one concept of “law of nature” in use, while there are in fact at least two. Strong laws are the principles pursued by fundamental physics: they are true, objective, and bear distinctive relationships to counterfactuals and explanation. Weak laws, by contrast, lack at least one of these distinctive characteristics but play central roles in both the “special sciences” and in everyday life. In Chapters Three and Four, I offer extended arguments against the two most prominent versions of reductionism about laws – Humeanism and law necessitarianism. According to philosophical Humeans, the laws of nature supervene upon the non-modal, non-nomic facts concerning the behavior of particular things at particular times and places. Law necessitarians, by contrast, argue that the laws are in fact metaphysically necessary, and that which laws there are is determined by a class of primitive, modally loaded facts concerning the essences, natures, or dispositions. I argue that both of these views are mistaken insofar as they disagree with well-entrenched scientific practices and those in favor of reductionism have failed to provided sufficient reason for thinking that these practices should be revised. Much of my argument is focused on the role played by a number of supposed methodological principles, including appeals to intuition, parsimony, and methodological naturalism. While the conclusions of this dissertation are explicitly constrained to laws, many of the arguments should be of interest to those who are concerned about philosophical methodology (especially in the role of intuition in philosophical argument) or the appropriate relation between metaphysics, science, and the philosophy of science.

If asked to explain why the Golds’ treatment of other colors in Red Rising is wrong, it is tempting to say something like “they are all human beings, and it is wrong to treat humans in this way!” In this essay, I’ll argue that this simple answer is considerably complicated by the fact that the different colors might not be members of the same biological species, and it is in fact unclear whether any of them are the same species as (...) current humans. Explaining why exactly this is so will lead us to an exploration the long-running debate in biology and philosophy over what exactly it means for two organisms to be “members of the same species.” I’ll begin by discussing the biological essentialism of Aristotle and his followers, who held that an individual organism’s species was determined by essence. One can easily imagine that the Golds might find this attractive, since it would suggest that their “superior” mental and physical capacities made them a different (and probably “higher”) species of humanity than the other colors. Unfortunately for Aristotle, this turns out to be inconsistent with Charles Darwin’s account of evolution by natural selection. This development has led many modern biologists and philosophers of biology to conceptualize species not as an abstract “form” that serves to classify organisms, but rather as a concrete collection of organisms relatively close to each other in space and time. In contrast to biological essentialism, this view of “species as concrete individual” might seem to support the Reds’ claim to the “same species” as the Gold, since they are both part of the same overarching society. Next, I’ll consider how we might tell where one species “ends” and another one “begins.” As it turns out, biologists have many ways of answering his question, each of which makes different judgments about the species of Red Rising’s characters. So, for example, the “Biological Species Concept” bases judgements about species membership on the ability to produce fertile offspring. This concept is far from perfect, however, for reasons that Red Rising makes clear: it doesn’t deal clearly with cases where reproduction is possible but very difficult (a Red and a Gold having a child) or for organisms that do not reproduce sexually (such as Pinks). I’ll then explore a few prominent alternatives to BSC, including both genetically and ecologically based species concepts, and consider their consequences for the society of Red Rising. I’ll conclude by advocating for a “pluralism” about species membership, and will suggest that the people of Red Rising (as well as in the real world) should beware of basing arguments for moral or political equality on the all-too-slippery notion of “shared humanity.” Instead, they should focus on the qualities that make the lives of the individuals (regardless of their species) worth caring about, such as their shared desires to avoid suffering and to lead fulfilling, meaningful lives.

This paper aims to mobilize the concept of “aleatory materialism” from Althusser’s posthumous work “The Underground Current of the Materialism of the Encounter” to theorize the emergence of a capitalist mode of production and analyze theoretical problems of thinking through the emergence of a communist mode of production out of capitalism. A “materialism of the encounter,” with its non-teleological account of causality can theorize the emergence of such a complicated object and help think through transitions without recourse to necessity or (...) sufficient reason. Retroactively, we can identify the discreet encounters that have “taken hold” in the institution of the capitalist mode of production, but we cannot trace with any necessity the islets that would form a communist mode of production.

One of the classic debates in cognitive science is between nativism and empiricism about the development of psychological capacities. In principle, the debate is empirical. However, in practice nativist hypotheses have also been challenged for relying on an ill-defined, or even unscientific, notion of innateness as that which is “not learned”. Here this minimal conception of innateness is defended on four fronts. First, it is argued that the minimal conception is crucial to understanding the nativism-empiricism debate, when properly construed; Second, (...) various objections to the minimal conception—that it risks overgeneralization, lacks an account of learning, frustrates genuine explanations of psychological development, and fails to unify different notions of innateness across the sciences—are rebutted. Third, it is argued that the minimal conception avoids the shortcomings of primitivism, the prominent view that innate capacities are those that are not acquired via a psychological process in development. And fourth, the minimal conception undermines some attempts to identify innateness with a natural kind. So in short, we have little reason to reject, and good reason to accept, the minimal conception of innateness in cognitive science. (shrink)

It is widely thought that functionalism and the qualia theory are better positioned to accommodate the ‘affective’ aspect of pain phenomenology than representationalism. In this paper, we attempt to overturn this opinion by raising problems for both functionalism and the qualia theory on this score. With regard to functionalism, we argue that it gets the order of explanation wrong: pain experience gives rise to the effects it does because it hurts, and not the other way around. With regard to the (...) qualia theory, we argue that it fails to capture the sense in which pain 's affective phenomenology rationalises various bodily-directed beliefs, desires, and behaviours. Representationalism, in contrast, escapes both of these problems: it gets the order of explanation right and it explains how pain 's affective phenomenology can rationalise bodily-directed beliefs, desires, and behaviours. For this reason, we argue that representationalism has a significant advantage in the debates about pain 's affective phenomenology. We end the paper by examining objections, including the question of what representationalists should say about so-called ‘disassociation cases’, such as pain asymbolia. (shrink)

The medium‐independence of computational descriptions has shaped common conceptions of computational explanation. So long as our goal is to explain how a system successfully carries out its computations, then we only need to describe the abstract series of operations that achieve the desired input–output mapping, however they may be implemented. It is argued that this abstract conception of computational explanation cannot be applied to so‐called real‐time computing systems, in which meeting temporal deadlines imposed by the systems with which a device (...) interfaces are constitutive of the computing tasks that a device performs. Instead, real‐time computing reveals the need for alternative conceptions of computational explanation, as well as computational implementation, that eschew medium‐independence. (shrink)

A review of Daniel Dennett's Intuition Pumps (W.V. Norton: 2013).

Common everyday materials such as textiles, foodstuffs, soil or skin can have complex, mutable and varied appearances. Under typical viewing conditions, most observers can visually recognize materials effortlessly, and determine many of their properties without touching them. Visual material perception raises many fascinating questions for vision researchers, neuroscientists and philosophers, yet has received little attention compared to the perception of color or shape. Here we discuss some of the challenges that material perception raises and argue that further philosophical thought should (...) be directed to how we see materials. (shrink)

Martin Peterson’s The Ethics of Technology: A Geometric Analysis of Five Moral Principles offers a welcome contribution to the ethics of technology, understood by Peterson as a branch of applied ethics that attempts ‘to identify the morally right courses of action when we develop, use, or modify technological artifacts’ (3). He argues that problems within this field are best treated by the use of five domain-specific principles: the Cost-Benefit Principle, the Precautionary Principle, the Sustainability Principle, the Autonomy Principle, and the (...) Fairness Principle. These principles are, in turn, to be understood and applied with reference to the geometric method. This method is perhaps the most interesting and novel part of Peterson’s book, and I’ll devote the bulk of my review to it. (shrink)

Joint practical deliberation is the activity of deciding together what to do. In this dissertation, I argue that several speech acts that we can use to alter our moral obligations – promises, offers, requests, demands, commands, and agreements – are moves within joint practical deliberation. -/- The dissertation begins by investigating joint practical deliberation. The resulting account implies that joint deliberation is more flexible than we usually recognize, in two ways. First, we can make joint decisions not only about what (...) we will do together, but also about what you or I will do alone. Second, we can deliberate by means of two distinct methods: propose-and-ratify, in which a proposed joint decision must be explicitly accepted to come into effect, and propose-and-challenge, in which a proposed joint decision comes into force unless it is explicitly challenged. -/- Varying these parameters generates a botany of different kinds of proposals we can make within joint deliberation. When we look at these proposals more closely, we make a surprising discovery: for each kind of proposal we can make in joint practical deliberation, there is an everyday speech act with the very same properties. A certain kind of proposal to make a joint decision regarding one’s own actions has the same normative effects, under the same conditions, as a promise. One kind of proposal to make a joint decision regarding one’s addressee’s actions has all the essential features of a command; another kind of deliberative proposal – with the same content but a different method of evaluation – looks exactly like a request. And so on. -/- These similarities are too systematic to be coincidental. The only explanation, I argue, is that these ordinary speech acts are identical to their doppelgängers within joint practical deliberation. Promises and offers are proposals to make joint decisions about what I will do. Commands, demands, and requests are proposals to make joint decisions about what you will do. And agreements are joint decisions about what we will do. Call this the deliberative theory of these speech acts. -/- Considering each speech act in turn, I defend the deliberative theory by arguing that it provides a uniquely powerful explanation of its targets’ social and moral significance. Once we see how naturally these speech acts fall out of our practice of joint deliberation, theories that treat them as sui generis – as many moral philosophers now do – will come to seem redundant and nonexplanatory. Conversely, thinking of promises, offers, commands, demands, requests, and agreements as moves within joint practical deliberation allows us to give an elegant and generative theory of these phenomena that have confounded moral philosophers for so long.
