Professional didactic engineering is essentially based on didactic analyses of work activities in order to design or improve training devices, focusing on the problem of competencies in characteristic situation classes. This article proposes an enrichment of this approach by focusing on professional concerns, either in a pedagogical adjustment approach or to understand specific organizers of the activity. In this second perspective, this contribution submits a multi-agenda generic analysis model of professional concerns, with a view to professional didactics.

There are many alleged problems with trusting another person’s moral testimony, perhaps the most prominent of which is that it fails to deliver moral understanding. Without moral understanding, one cannot do the right thing for the right reason, and so acting on trusted moral testimony lacks moral worth. This chapter, however, argues that moral advice differs from moral testimony, differs from it in a way that enables a defender of moral advice to parry this worry about moral worth. The basic (...) idea is that an advisor and an advisee can together constitute a joint agent, and that this joint agent’s action can indeed have moral worth. So while the advisee himself might not do the right thing for the right reason (this because all alone he lacks the right reason), and while the advisor herself might not do the right thing for the right reason (this because all alone she does not do the right thing), they together do the right for the right reason.

This article examines Harold Ramis’s 2005 noir comedy _The Ice Harvest_ as the critically dystopian counter-panel to his beloved 1993 film _Groundhog Day_, a film frequently discussed within the paradigm of utopia. While starkly different in genre, tone, and reception, the two films comprise a dialectical dyad that registers the historical transition from the utopian cultural effervescence of the early 1990s to the tragic foreclosure of imaginative horizons and the dystopian transformation of economic, political, and social landscapes in the new (...) millennium. In _The Ice Harvest_, the author argues, this is achieved through a strategic reactivation of film noir as a variant of the critical dystopia. (shrink)

During his career, Ronald Dworkin wrote extensively on an impressive range of issues in moral, political, and legal philosophy, but, like many of his contemporaries, international law remained a topic of relative neglect. His most sustained work on international law is a posthumously published article, “A New Philosophy for International Law” (2013), which displays some familiar aspects of his views in general jurisprudence, in addition to some novel (though perhaps surprising) arguments as well. This paper argues that the moralized account (...) of international law we might have expected is conspicuously missing from this posthumous article; with Dworkin advancing an argument based on a form of political realism instead.

In the philosophy of climate science, debate surrounding the issue of variety of evidence has mostly taken the form of attempting to connect these issues in climate science and climate modeling with philosophical accounts of what has come to be known as “robustness analysis.” I argue that an “explanatory” conception of robustness is the best candidate for understanding variety of evidence in climate science. I apply the analysis to both examples of model agreement, as well at to the convergence of (...) evidence from both model and non-model sources. (shrink)

According to Eric Olson, the Thinking Animal Argument (TAA) is the best reason to accept animalism, the view that we are identical to animals. A novel criticism has been advanced against TAA, suggesting that it implicitly employs a dubious epistemological principle. I will argue that other epistemological principles can do the trick of saving the TAA, principles that appeal to recent issues regarding disagreement with peers and experts. I conclude with some remarks about the consequence of accepting these modified principles, (...) drawing out some general morals in defending animalism. (shrink)

In computer simulations of physical systems, the construction of models is guided, but not determined, by theory. At the same time simulations models are often constructed precisely because data are sparse. They are meant to replace experiments and observations as sources of data about the world; hence they cannot be evaluated simply by being compared to the world. So what can be the source of credibility for simulation models? I argue that the credibility of a simulation model comes not only (...) from the credentials supplied to it by the governing theory, but also from the antecedently established credentials of the model building techniques employed by the simulationists. In other words, there are certain sorts of model building techniques which are taken, in and of themselves, to be reliable. Some of these model building techniques, moreover, incorporate what are sometimes called “falsifications.” These are contrary-to-fact principles that are included in a simulation model and whose inclusion is taken to increase the reliability of the results. The example of a falsification that I consider, called artificial viscosity, is in widespread use in computational fluid dynamics. Artificial viscosity, I argue, is a principle that is successfully and reliably used across a wide domain of fluid dynamical applications, but it does not offer even an approximately “realistic” or true account of fluids. Artificial viscosity, therefore, is a counter-example to the principle that success implies truth – a principle at the foundation of scientific realism. It is an example of reliability without truth.

This paper argues that under some conditions, when one person acts on the direction of another person, the two of them thereby act together, and that this explains why both the director and the directee can be responsible for what is done. In other words, a director and a directee can be a joint agent, one whose members are responsible for what they together do. This is most clearly so when the directive is a command. But it is also sometimes (...) so when the directive is a bit of advice. (shrink)

We use Nietzsche’s On the Genealogy of Morality as a touchstone for comprehending Trump’s appeal and victory. Following Nietzsche’s concerns, the most noteworthy puzzle is that of Trump’s peculiar popularity, especially given his impolitic statements and policy proposals that often appear in tension with the interests of his voter base. While Nietzsche’s discussions of power and resentment would seem obvious starting points to examine the success of Trump and Trumpism, we contend that these provide largely superficial and, at best, incomplete (...) explanations. Instead, informed by Nietzsche’s moral psychology, we analyze Trump’s strategy in the context of the instinctual need for self-preservation. Trump’s amplification of this need through his rhetoric and cultivation of negative emotions, including resentment, has led to a revaluation that diminishes humanity. We conclude by drawing out the implications of Nietzsche’s view, revealing a forceful Nietzschean critique of Trump’s methods and values. (shrink)

Even though Kant’s theory of cognition (Erkenntnis) is central to his Critique of Pure Reason, it has rarely been asked what exactly Kant means by the term “cognition”. Against the widespread assumption that cognition (in the most relevant sense of that term) can be identified with knowledge or if not, that knowledge is at least a species of cognition, we argue that the concepts of cognition and knowledge in Kant are not only distinct, but even disjunct. To show this, we (...) first (I) investigate Kant’s explicit characterizations of the nature of cognition. As it turns out, he introduces several different notions that must be carefully distinguished before identifying the one that is central to his project in the first Critique. We then (II) consider the basic features of Kant’s conception of knowledge, indicating both how it involves assent and objective justification and how it relates to our contemporary conception. Next (III), we compare and contrast Kant’s understanding of cognition and his conception of knowledge in a way that allows us to present their fundamental differences and connections. We argue that while cognition, in the most relevant sense, is a species of representation that differs from other representations in that it involves the conceptual determination of a sensibly given object, knowledge (for Kant) is a kind of assent to a judgment that requires consciousness of a sufficient epistemic ground. Finally (IV), by appreciating the differences between cognition and knowledge, we explain several of the implications this conception of cognition has for some of Kant’s main claims in the Critique of Pure Reason as a whole. Among other things, we show how Kant can deny cognition of specific things in themselves while allowing philosophical knowledge about things in themselves in general (e.g. that they exist, are not in space and time, etc.).

In a large and impressive body of published work, Quayshawn Spencer has meticulously articulated and defended a metaphysical project aimed at resuscitating a biological conception of race—one free from many of the pitfalls of biological essentialism. If successful, such a project would be highly rewarding, since it would provide a compelling response to philosophers who have denied the genuine existence of race while avoiding the very dangers that they sought to avoid. The aim of this paper is to subject those (...) moves to careful scrutiny and thereby appraise the prospects for a new biologism about race. (shrink)

Self-deception poses longstanding and fascinating paradoxes. Philosophers have questioned whether, and how, self-deception is even possible; evolutionary theorists have debated whether it is adaptive. For Sigmund Freud self-deception was a fundamental key to understanding the unconscious, and from The Bible to The Great Gatsby literature abounds with characters renowned for their self-deception. But what exactly is self-deception? Why is it so puzzling? How is it performed? And is it harmful? ...

kant’s critique of pure reason undertakes a systematic investigation of the possibility of synthetic cognition a priori so as to determine whether this kind of cognition is possible in the case of traditional metaphysics.1 While much scholarly attention has been devoted to the distinction between analytic and synthetic judgments as well as to that between the a priori and the a posteriori, less attention has been devoted to understanding exactly what cognition is for Kant. In particular, it is often insufficiently (...) clear what kind of mental state cognition is, what the exact nature of the conditions on cognition is, and how they are satisfied in the case of human beings. To bring greater clarity to... (shrink)

Violations of the Bell inequalities in EPR-Bohm type experiments have set the literature on the metaphysics of microscopic systems to flirting with some sort of metaphysical holism regarding spatially separated, entangled systems. The rationale for this behavior comes in two parts. The first part relies on the proof, due to Jon Jarrett [2] that the experimentally observed violations of the Bell inequalities entail violations of the conjunction of two probabilistic constraints. Jarrett called these two constraints locality and completeness. We prefer (...) the terminology of locality and factorizability.[3] The first part of the rationale for metaphysical holism urges that only Jarrett’s locality allows for “peaceful coexistence” between any model of EPR-Bohm type experiments and special relativity. Factorizability, it is suggested, must be jettisoned. (shrink)

At some point in the future – perhaps within the next few decades – it will be possible for foetuses to develop completely outside the womb. Ectogenesis, as this technology is called, raises substantial issues for the abortion debate. One such issue is that it will become possible for a woman to have an abortion, in the sense of having the foetus removed from her body, but for the foetus to be kept alive. We argue that while there is a (...) right to an abortion, there are reasons to doubt that there is a right to the death of the foetus. Our strategy in this essay is to consider and reject three arguments in favour of this latter right. The first claims that women have a right not to be biological mothers, the second that women have a right to genetic privacy, and the third that a foetus is one's property. Furthermore, we argue that it follows from rejecting the third claim that genetic parents also lack a right to the destruction of cryopreserved embryos used for in vitro fertilization. The conclusion that a woman possesses no right to the death of the foetus builds upon the claims that other pro-choice advocates, such as Judith Jarvis Thomson, have made. (shrink)

According to one interpretation of Aristotle’s famous thesis, to say that action is the conclusion of practical reasoning is to say that action is itself a judgment about what to do. A central motivation for the thesis is that it suggests a path for understanding the non-observational character of practical knowledge. If actions are judgments, then whatever explains an agent’s knowledge of the relevant judgment can explain her knowledge of the action. I call the approach to action that accepts Aristotle’s (...) thesis so understood Normativism. There are many reasons to doubt Normativism. My aim in this paper is to defend Normativism from a pair of arguments that purport to show that a normative judgment could not constitute an event in material reality and also the knowledge of such a happening. Both highlight a putative mismatch between the natures of, on the one hand, an agent’s knowledge of her normative judgment and, on the other, her knowledge of her own action. According to these objections, knowledge of action includes (a) perceptual knowledge and (b) knowledge of what one has already done. But knowledge of a normative judgment includes neither. Hence knowledge of action cannot simply be knowledge of a normative judgment. (shrink)

In his latest book, Eric Scerri presents a completely original account of the nature of scientific progress. It consists of a holistic and unified approach in which science is seen as a living and evolving single organism. Instead of scientific revolutions featuring exceptionally gifted individuals, Scerri argues that the "little people" contribute as much as the "heroes" of science. To do this he examines seven case studies of virtually unknown chemists and physicists in the early 20th century quest to discover (...) the structure of the atom. They include the amateur scientist Anton van den Broek who pioneered the notion of atomic number as well as Edmund Stoner a then physics graduate student who provided the seed for Pauli's Exclusion Principle. Another case is the physicist John Nicholson who is virtually unknown and yet was the first to propose the notion of quantization of angular momentum that was soon put to good use by Niels Bohr. Instead of focusing on the logic and rationality of science, Scerri elevates the role of trial and error and multiple discovery and moves beyond the notion of scientific developments being right or wrong. While criticizing Thomas Kuhn's notion of scientific revolutions he agrees with Kuhn that science is not drawn towards an external truth but is rather driven from within. The book will enliven the long-standing debate on the nature of science, which has increasingly shied away from the big question of "what is science?". (shrink)

A popular argument against direct duties for individuals to address climate change holds that only states and other powerful collective agents must act. It excuses individual actions as harmless since they are neither necessary nor sufficient to cause harm, arise through normal activity, and have no clear victims. Philosophers have challenged one or more of these assumptions; however, I show that this definition of harm also excuses states and other collective agents. I cite two examples of this in public discourse (...) and suggest we reconsider the notion of harmful action in our discussions about climate change. (shrink)

A recent solution to the Body-Minus problem, which is a problem of material constitution, claims that ordinary proper parts (such as left feet) exist, but the complements of these objects (such as left-foot complements) do not exist. In this paper, I examine a defense of this solution from the worry of arbitrariness and from its ineffectiveness against a revised version of the problem that focuses on the head, and I show that this defense fails.

I argue that zombies are inconceivable. More precisely, I argue that the conceivability-intuition that is used to demonstrate their possibility has been misconstrued. Thought experiments alleged to feature zombies founder on the fact that, on the one hand, they _must_ involve first-person imagining, and yet, on the other hand, _cannot_. Philosophers who take themselves to have imagined zombies have unwittingly conflated imagining a creature who lacks consciousness with imagining a creature without also imagining the consciousness it may or may not (...) possess.

What is group well-being? There is, as of yet, shockingly little philosophical literature explicitly aiming to answer this question. This essay sketches some of the logical space of possible answers, and nudges us to seriously consider certain overlooked options. There are several importantly different ways the well-being of a collective or a group could be related to the well-being of the individuals who constitute it: 1) eliminativism, 2) functionalism, 3) partialism, or 4) the independent view. If the relation between individual (...) and collective well-being is either functional or partial, then we face a further question: What is the direction of constitutive dependence? Does the well-being of a group depend upon the well-being of the well-being of the individuals who compose it, or does the well-being of an individual depend upon the well-being of the groups to which they belong? Or both? These questions raise some puzzles that I begin to resolve. I conclude that there might be a wide variety of ways the well-being of a collective obtains, only some of which are related to the well-being of the individuals who are its members. In the end, I hope to vindicate the thought that an injury to one is an injury to all. (shrink)

Scientific modelling is a value-laden process: the decisions involved can seldom be made using 'scientific' criteria alone, but rather draw on social and ethical values. In this paper, we draw on a body of philosophical literature to analyze a COVID-19 vaccination model, presenting a case study of social and ethical value judgments in health-oriented modelling. This case study urges us to make value judgments in health-oriented models explicit and interpretable by non-experts and to invite public involvement in making them.

During the last twenty years, Kant's theory of biology has increasingly attracted the attention of scholars and developed into a field which is growing rapidly in importance within Kant studies. The volume presents fifteen interpretative essays written by experts working in the field, covering topics from seventeenth- and eighteenth-century biological theories, the development of the philosophy of biology in Kant's writings, the theory of organisms in Kant's Critique of the Power of Judgment, and current perspectives on the teleology of nature.

It seems that we can know moral truths. We are also rather reluctant to defer to moral testimony. But it’s not obvious how moral cognitivism is compatible with pessimism about moral testimony. If moral truths are knowable, shouldn’t it be possible for others to know moral truths you don’t know, so that it is wise for you to defer to what they say? Or, alternatively, if it’s always reasonable to refuse to defer to the wisest among us, doesn’t this show (...) that morality is not genuinely cognitive? There is a tension in our commonsense moral epistemology. In this chapter I (a) explicate this tension, (b) criticize how others have attempted to resolve it, and finally (c) explain how Rossian deontology helps us see that the tension is only apparent: morality is indeed knowable, despite the fact that it is usually wise to refuse to defer to moral testimony.

This paper discusses an analogical argument for the compatibility of the evidential argument from evil and skeptical theism. The argument is based on an alleged parallel between the paradox of the preface and the case of apparently pointless evil. I argue that the analogical argument fails, and that the compatibility claim is undermined by the epistemic possibility of inaccessible reasons for permitting apparently pointless evils. The analogical argument fails, because there are two crucial differences between the case of apparently pointless (...) evil and the case of the preface. First, in the preface case, our non-cumulative evidence supports a claim of error, whereas the analogical argument is based on the idea that our non-cumulative evidence supports the success claim that there’s at least one instance of truly pointless evil. Second, our non-cumulative evidence of error in the case of the preface rests on a track record establishing author fallibility; in the case of apparently pointless evils, there is no relevant track record to support the claim that some apparently pointless evils are truly pointless. These differences, together with certain plausible assumptions about our fallibility and reliability with respect to propositions about evil, also indicate that inaccessible reasons for permitting apparently pointless evil are epistemically possible. Given the epistemic possibility of such reasons, we’re in no position to judge whether such reasons are present in every case no matter how large the set of such evils may be. (shrink)

We propose that doping be legalized under medical supervision. First, we discuss two motivations for allowing medically supervised doping. We reject the ‘compromised choice/harm minimization’ motivation as unlikely to win the support of athletes. We agree that it could lead to an arms race. Instead, we favor full acceptance of doping under medical supervision and answer Reid’s spirit of sport objection to medical manipulation. After presenting a set of guiding principles, we use them to answer the arms race objection and (...) rebut one of the most prominent objections in the literature about the safety of medically supervised doping, the game-theoretic objection.

The subject of this two-part article is the bearing of Søren Kierkegaard’s writings, and of their reception, upon the development of Religionswissenschaft or the comparative study of religion. This first part opens by taking account of Kierkegaard’s own awareness of, and relationship to, “non-Christian” religions, including his late reading of Schopenhauer; then considers Kierkegaard in juxtaposition with his contemporary F. Max Müller, the Sanskritist and foundational pioneer of comparative religion, and the two men’s contrasting relations to F.W.J. Schelling; and finally (...) examines the interest taken in Kierkegaard by William James, Max Weber, and Gerardus van der Leeuw as early twentieth-century contributors through three different disciplines to the study of comparative religion.

This interdisciplinary work is a collection of major essays on reasoning: deductive, inductive, abductive, belief revision, defeasible, cross cultural, conversational, and argumentative. They are each oriented toward contemporary empirical studies. The book focuses on foundational issues, including paradoxes, fallacies, and debates about the nature of rationality, the traditional modes of reasoning, as well as counterfactual and causal reasoning. It also includes chapters on the interface between reasoning and other forms of thought. In general, this last set of essays represents growth (...) points in reasoning research, drawing connections to pragmatics, cross-cultural studies, emotion and evolution. (shrink)

"The king is dead. Long live the king!" In early modern Europe, the king's body was literally sovereign—and the right to rule was immediately transferrable to the next monarch in line upon the king's death. In The Royal Remains, Eric L. Santner argues that the "carnal" dimension of the structures and dynamics of sovereignty hasn't disappeared from politics. Instead, it migrated to a new location—the life of the people—where something royal continues to linger in the way we obsessively track and (...) measure the vicissitudes of our flesh. Santner demonstrates the ways in which democratic societies have continued many of the rituals and practices associated with kingship in displaced, distorted, and usually, unrecognizable forms. He proposes that those strange mental activities Freud first lumped under the category of the unconscious—which often manifest themselves in peculiar physical ways—are really the uncanny second life of these "royal remains," now animated in the body politic of modern neurotic subjects. Pairing Freud with Kafka, Carl Schmitt with Hugo von Hofmannsthal,and Ernst Kantorowicz with Rainer Maria Rilke, Santner generates brilliant readings of multiple texts and traditions of thought en route to reconsidering the sovereign imaginary. Ultimately, The Royal Remains locates much of modernity—from biopolitical controversies to modernist literary experiments—in this transition from subjecthood to secular citizenship. This major new work will make a bold and original contribution to discussions of politics, psychoanalysis, and modern art and literature. (shrink)

Some key political challenges today, e.g. climate change, are future oriented. The intergenerational setting differs in some notable ways from the intragenerational one, creating obstacles to theorizing about intergenerational justice. One concern is that as the circumstances of justice do not pertain intergenerationally, intergenerational justice is not meaningful. In this paper, I scrutinize this worry by analysing the presentations of the doctrine of the circumstances of justice by David Hume and John Rawls. I argue that we should accept the upshot (...) of their idea, that justice is context sensitive, even if this at first sight seems to invalidate intergenerational justice. On the basis of moral constructivism, I subsequently provide a fresh reading of the doctrine according to which it conveys the idea that justice is the solution to a practical problem. However, as the problem background is evolving, we need to properly characterize the relevant practical problem in order to make ethical theorizing relevant. Contrary to what has been claimed, the circumstances of justice do not then clash with intergenerational justice, but are the necessary presuppositions for its advancement. (shrink)

This essay argues that Plato in the Republic needs an account of why and how the three distinct parts of the soul are parts of one soul, and it draws on the Phaedrus and Gorgias to develop an account of compositional unity that fits what is said in the Republic.

This chapter demonstrates how Sophie de Grouchy (1764–1822) anticipates the famous modern-day distinction between positive and negative liberty in her late eighteenth-century writings. It is argued that, on these grounds, De Grouchy deserves a rightful place in the history of the liberal tradition, a tradition that is typically depicted as the exclusive province of men. To support this claim, this chapter examines De Grouchy’s ideas in comparison with Rousseau’s and Adam Smith’s views on justice and property rights. This sets the (...) context in which De Grouchy introduces her distinction between positive and negative rights, a distinction that maps onto the modern-day divide between negative and positive liberty. It is shown how, in her writings, political issues of rights and justice intersect with moral issues to do with virtue and with the proper education of virtuous citizens who are also free. (shrink)

Social referencing informs and regulates one’s relation with the environment as a function of the perceived appraisals of social partners. Increased emphasis on relational and social contexts in the study of emotion makes this interpersonal process particularly relevant to the field. However, theoretical conceptualizations and empirical operationalizations of social referencing are disjointed across domains and populations of study. This article seeks to unite and refine the study of this construct by providing a clear and comprehensive definition of social referencing. Our (...) perspective presents social referencing and social appraisal as coterminous processes and emphasizes the importance of a relational and interpersonal approach to the study of emotion. We conclude by outlining possible lines of research on this construct. (shrink)

This volume provides English translations of texts that form the essential background to Kant's Critique of Pure Reason. Presenting the projects of Kant's predecessors and contemporaries in eighteenth-century Germany, it enables readers to understand the positions that Kant might have identified with 'pure reason', the criticisms of pure reason that had developed prior to Kant's, and alternative attempts at synthesizing empiricist elements within a rationalist framework. The volume contains chapters on Christian Wolff, Martin Knutzen, Alexander Baumgarten, Christian Crusius, Leonhard Euler, (...) Johann Lambert, Marcus Herz, Johann Eberhard, and Johann Tetens. Each chapter includes a brief introduction that provides succinct biographical and bibliographical information on these authors, a concise account of their projects, and information on the importance of these projects to Kant's First Critique. Extensive references to the First Critique, brought together in a concordance, highlight the potential relevance of each text. (shrink)

This is a study of Plato's use of the character Socrates to model what philosophy is. The study focuses on the Apology, and finds that philosophy there is the love of wisdom, where wisdom is expertise about how to live, of the sort that only gods can fully have, and where Socrates loves wisdom in three ways, first by honoring wisdom as the gods' possession, testing human claims to it, second by pursuing wisdom, examining himself as he examines others, to (...) achieve a more well justified set of beliefs about how to live, and third by trying to live wisely, insofar as he can, which includes exhorting others to care about living wisely than anything else. The essay also includes some suggestions about how Plato criticizes and revises this model of philosophy outside the Apology. (shrink)

The notion of domain specificity plays a central role in some of the most important debates in cognitive science. Yet, despite the widespread reliance on domain specificity in recent theorizing in cognitive science, this notion remains elusive. Critics have claimed that the notion of domain specificity can't bear the theoretical weight that has been put on it and that it should be abandoned. Even its most steadfast proponents have highlighted puzzles and tensions that arise once one tries to go beyond (...) an initial intuitive sketch of what domain specificity involves. In this paper, we address these concerns head on by developing an account of what it means for a cognitive mechanism to be domain specific that overcomes the obstacles that have made domain specificity seem so problematic. We then apply this understanding of domain specificity to one of the key debates that it has figured prominently in—the rationalism-empiricism debate concerning the origins of cognitive traits—and introduce several related theoretical notions that work alongside domain specificity in helping to clarify what makes a view more (or less) rationalist. This example illustrates how the notion of domain specificity can, and should, continue to play a central role in ongoing debates in cognitive science. (shrink)

Bellʼs 1964 theorem causes a severe problem for the notion that correlations require explanation, encapsulated in Reichenbachʼs principle of common cause. Despite being a hallmark of scientific thought, dropping the principle has been widely regarded as much less bitter medicine than the perceived alternative—dropping relativistic causality. Recently, however, some authors have proposed that modified forms of Reichenbachʼs principle could be maintained even with relativistic causality. Here we break down Reichenbachʼs principle into two independent assumptions—the principle of common cause proper and (...) factorization of probabilities. We show how Bellʼs theorem can be derived from these two assumptions plus relativistic causality and the law of total probability for actual events, and we review proposals to drop each of these assumptions in light of the theorem. In particular, we show that the non-commutative common causes of Hofer-Szabó and Vecsernyés fail to have an analogue of the notion that the common causes can explain the observed correlations. Moreover, we show that their definition can be satisfied trivially by any quantum product state for any quantum correlations. We also discuss how the conditional states approach of Leifer and Spekkens fares in this regard. (shrink)
