Using formal systems to represent and reason about uncertainty.

Recent work in psychology and experimental philosophy has shown that judgments of actual causation are often influenced by consideration of defaults, typicality, and normality. A number of philosophers and computer scientists have also suggested that an appeal to such factors can help deal with problems facing existing accounts of actual causation. This article develops a flexible formal framework for incorporating defaults, typicality, and normality into an account of actual causation. The resulting account takes actual causation to be both graded and (...) comparative. We then show how our account would handle a number of standard cases. 1 Introduction2 Causal Models3 The HP Definition of Actual Causation4 The Problem of Isomorphism5 Defaults, Typicality, and Normality6 Extended Causal Models7 Examples7.1 Omissions7.2 Knobe effects7.3 Causes versus background conditions7.4 Bogus prevention7.5 Causal chains7.6 Legal doctrines of intervening causes7.7 Pre-emption and short circuits8 Conclusion.

We propose a new definition of actual causes, using structural equations to model counterfactuals. We show that the definition yields a plausible and elegant account of causation that handles well examples which have caused problems for other definitions and resolves major difficulties in the traditional account.

"Although the task of formulating an appropriate policy response to the problem of anthropogenic climate change is one that raises a number of very difficult normative issues, environmental ethicists have not played an influential role in government deliberations. This is primarily due to their rejection of many of the assumptions that structure the debates over policy. This book offers a philosophical defense of these assumptions, in order to overcome the major conceptual barriers to the participation of philosophers in these debates. (...) There are five important barriers: First, the policy debate presupposes a stance of liberal neutrality, as a result of which it does not privilege any particular set of environmental values over other concerns. Second, it assumes ongoing economic growth, along with a commitment to what is sometimes called a weak sustainability framework when analyzing the value of the bequest being made to future generations. Third, it treats climate change as fundamentally a collective action problem, not an issue of distributive justice. Fourth, there is the acceptance of cost-benefit analysis, or more precisely, the view that a carbon pricing regime should be guided by our best estimate of the social cost of carbon. And finally, there is the view that when this calculation is undertaken, it is permissible to discount costs and benefits, depending on how far removed they are from the present. This book attempts to make explicit and defend these presuppositions, and in so doing offer philosophical foundations for the debate over climate change policy"--. (shrink)

Joseph Grange's beautifully written book provides a unique synthesis of two major figures of world philosophy, John Dewey and Confucius, and points the way to a global philosophy based on American and Confucian values. Grange concentrates on the major themes of experience, felt intelligence, and culture to make the connections between these two giants of Western and Eastern thought. He explains why the Chinese called Dewey "A Second Confucius," and deepens our understanding of Confucius's concepts of the way (dao) (...) of human excellence (ren). The important dimensions of American and Chinese cultural philosophy are welded into an argument that calls for the liberation of what is finest in both traditions. The work gives a new appreciation of fundamental issues facing Chinese and American relations and brings the opportunities and dangers of globalization into focus. (shrink)

One of the most influential ideas in the field of business ethics has been the suggestion that ethical conduct in a business contextshould be analyzed in terms of a set of fiduciary obligations toward various “stakeholder” groups. Moral problems, according to this view, involve reconciling such obligations in cases where stakeholder groups have conflicting interests. The question posed in this paper is whether the stakeholder paradigm represents the most fruitful way of articulating the moral problems that arise in business. By (...) way of contrast, I outline two other possible approaches to business ethics: one, a more minimal conception, anchored in the notion of a fiduciary obligation toward shareholders; and the other, a broader conception, focused on the concept of market failure. I then argue that the latter offers a more satisfactory framework for the articulation of the social responsibilities of business. (shrink)

Introduction -- Instrumental rationality -- Social order -- Deontic constraint -- Intentional states -- Preference noncognitivism -- A naturalistic perspective -- Transcendental necessity -- Weakness of will -- Normative ethics.

There is an idea, extremely common among social contract theorists, that the primary function of social institutions is to secure some form of cooperative benefit. If individuals simply seek to satisfy their own preferences in a narrowly instrumental fashion, they will find themselves embroiled in collective action problems – interactions with an outcome that is worse for everyone involved than some other possible outcome. Thus they have reason to accept some form of constraint over their conduct, in order to achieve (...) this superior, but out-of-equilibrium outcome. A social institution can be defined as a set of norms that codify these constraints.1 Simplifying somewhat, one can then say that social institutions exist in order to secure gains in Pareto-efficiency.

Ian Stoner has recently argued that we ought not to colonize Mars because doing so would flout our pro tanto obligation not to violate the principle of scientific conservation, and there is no countervailing considerations that render our violation of the principle permissible. While I remain agnostic on, my primary goal in this article is to challenge : there are countervailing considerations that render our violation of the principle permissible. As such, Stoner has failed to establish that we ought not (...) to colonize Mars. I close with some thoughts on what it would take to show that we do have an obligation to colonize Mars and related issues concerning the relationship between the way we discount our preferences over time and projects with long time horizons, like space colonization.

(1968 [1922]). It amounts to the claim that social phenomena must be explained by showing how they result from individual actions, which in turn must be explained through reference to the intentional states that motivate the individual actors. It involves, in other words, a commitment to the primacy of what Talcott Parsons would later call “the action frame of reference” (Parsons 1937: 43-51) in social-scientific explanation. It is also sometimes described as the claim that explanations of “macro” social phenomena must (...) be supplied with “micro” foundations, ones that specify an action-theoretic mechanism (Alexander, 1987).

False belief tasks have enjoyed a monopoly in the research on children’s development of a theory of mind. They have been granted this status because they promise to deliver an unambiguous assessment of children’s understanding of the representational nature of mental states. Their poor cousins, true belief tasks, have been relegated to occasional service as control tasks. That this is their only role has been due to the universal assumption that correct answers on true belief tasks are inherently ambiguous regarding (...) the level of the child’s understanding of mental states. It has also been due to the universal assumption that nothing in the child’s developing theory of mind would lead to systematically incorrect answers on true belief tasks. We review new findings that 4- and 5-year-olds do err, systematically and profoundly, on the true belief versions of all the extant belief tasks. This reveals an intermediate level of understanding in the development of children’s theory of mind. Researchers have been unaware of this intermediate level because it produces correct answers in false belief tasks. A simple two-task battery—one true belief task and one false belief task—is sufficient to remove the ambiguity from each task. The new findings show that children do not acquire an understanding of beliefs, and hence a representational theory of mind, until after 6 years of age, or 2 years later than most developmental psychologists have concluded. This raises the question of how to interpret other new findings that infants are able to pass false belief tasks. We review these new infant studies, as well as recent studies on chimpanzees, in light of older children’s failure on true belief tasks, and end with some speculation about how all of these new findings might be reconciled.

The use of agency theory remains highly controversial among business ethicists. While some regard it as an essential tool for analyzing and understanding the recent spate of corporate ethics scandals, others argue that these scandals might not even have occurred had it not been for the widespread teaching of agency theory in business schools. This paper presents a qualified defense of agency theory against these charges, first by identifying the theoretical commitments that are essential to the theory (in order to (...) distinguish between agency theory itself and certain incorrect interpretations that have been widely promulgated), and second, by specifying more clearly the different ways that agency theory can be used to analyze relations within the firm. The recommendation that follows from this analysis is that agency theory be used as a critical-diagnostic tool, to identify the points at which both firms and markets will be vulnerable to breakdown in the absence of moral constraint.

What experimental game theorists may have demonstrated is not that people are systematically irrational but that human rationality is heavily scaffolded. Remove the scaffolding, and we do not do very well. People are able to get on because they “offload” an enormous amount of practical reasoning onto their environment. As a result, when they are put in novel or unfamiliar environments, they perform very poorly, even on apparently simple tasks. -/- This observation is supported by recent empirically informed shifts in (...) philosophy of mind toward a view of cognition as (to cite the current slogan) “embodied, embedded, enactive, extended.” Andy Clark and others have made a very plausible case for the idea that a proper assessment of human cognitive competence must include environmental components. To limit our attention to what lies within the skin-skull boundary is, in effect, to miss the big story on human rationality. Insofar as we are rational, it is often because of our ingenuity at developing “work-arounds” to the glitches in the fast-and-frugal heuristic problem-solving capabilities that natural selection has equipped us with. And these work-arounds often involve a detour through the environment (so-called offloading of cognitive burdens). -/- When it comes to practical rationality, things are no different. Yet in many discussions of “the will,” there is still a tendency to put too much emphasis on what goes on inside the agent’s head. Our objective in this chapter is to articulate this conception of “the extended will” more clearly, using the strategies that people employ to overcome procrastination for the central set of examples. Procrastination, in our view, constitutes a particular type of self-control problem, one that is particularly amenable to philosophical reflection, not only because of the high volume of psychological research on the subject but also because of the large quantity of “self-help” literature in circulationa literature that provides an invaluable perspective on the everyday strategies that people use in order to defeat (or, better yet, circumvent) this type of self-defeating behavior pattern. In general, what we find is that the internalist bias that permeates discussions of the will gives rise to a set of practical recommendations that overemphasize changing the way one thinks about a task, while ignoring the much richer set of strategies that are available in the realm of environmental scaffolding. In the concluding section, we highlight some of the policy implications of this, particularly regarding social trends involving the dismantling of support structures. (shrink)

It is generally agreed that the method of explication consists in replacing a vague, presystematic notion (the explicandum) with a precise notion (the explicatum) formulated in a systematic context. However, Carnap and others who have used this and related terms appear to hold inconsistent views as to what constitutes an adequate explication. The central feature of the present explication of 'explication' is the correspondence condition: permitting the explicandum to deviate from some established "ordinary-language" conventions but, at the same time, requiring (...) that the explicatum correspond (via an effective translation) to the chosen "definitive intension" of the explicandum. (In effect, the first stages of an explication provide an informal characterization of a vague and possibly inconsistent language convention.) The present account of explication contrasts sharply with that sketched by Quine in Word and Object (although Quine accepts a correspondence condition of a sort). The terms `explication 1 ' and `explication 2 ' are used to indicate these quite different senses of the term. In Kaplan's terminology, explication 1 is intended to remedy "external vagueness" while explication 2 is intended to remedy "internal vagueness.". (shrink)

The appropriateness of S5 as a logic of knowledge has been attacked at some length in the philosophical literature. Here one particular attack based on the interplay between knowledge and belief is considered: Suppose that knowledge satisfies S5, belief satisfies KD45, and both the entailment property (knowledge implies belief) and positive certainty (if the agent believes something, she believes she knows it) hold. Then it can be shown that belief reduces to knowledge: it is impossible to have false beliefs. While (...) the entailment property has typically been viewed as perhaps the least controversial of these assumptions, an argument is presented that it can plausibly be viewed as the culprit. More precisely, it is shown that this attack fails if we weaken the entailment property so that it applies only to objective (nonmodal) formulas, rather than to arbitrary formulas. Since the standard arguments in favor of the entailment property are typically given only for objective formulas, this observation suggests that care must be taken in applying intuitions that seem reasonable in the case of objective formulas to arbitrary formulas.

We propose new definitions of (causal) explanation, using structural equations to model counterfactuals. The definition is based on the notion of actual cause, as defined and motivated in a companion article. Essentially, an explanation is a fact that is not known for certain but, if found to be true, would constitute an actual cause of the fact to be explained, regardless of the agent's initial uncertainty. We show that the definition handles well a number of problematic examples from the literature.

ABSTRACT I begin by developing a challenge for the Higher-Order Thought variant of Higher-Order representational theories of consciousness. The challenge is to account for the distinctive phenomenal character of visual experience—its presentational character. After setting out the challenge, I articulate a novel form of Higher-Order theory that can account for presentational character—the Map Theory of consciousness. The theory’s distinctive claim is that the relevant higher-order representations have a cartographic format.

Pitt :735–741, 2017) has argued that reductive representationalism entails an absurdity akin to the “paramechanical hypothesis” Ryle attributed to Descartes. This paper focuses on one version of reductive representationalism: the property-complex theory. We contend that at least insofar as the property-complex theory goes, Pitt is wrong. The result is not just a response to Pitt, but also a clarification of the aims and structure of the property-complex theory.

Within any adversarial rule-governed system, it often takes time for strategically motivated agents to discover effective exploits. Once discovered, these strategies will soon be copied by all other participants. Unless it is possible to adjust the rules to preclude them, the result will be a degradation of the performance of the system. This is essentially what has happened to public political discourse in democratic states. Political actors have discovered, not just that the norm of truth can be violated in specific (...) ways, but that many of the norms governing rational deliberation can also be violated, not just without penalty, but often for significant political gain. As a result, the level of noise has come to drown out the signal. The post-truth political condition is the cumulative result of innovations developed by actors who adopt an essentially strategic orientation toward political communications. (shrink)

On the other hand, a slight generalization of recursive models, models where all equations have unique solutions, is shown to be incomparable in expressive power to counterfactual structures, despite the fact that the Galles and Pearl arguments should apply to them as well. The problem with the Galles and Pearl argument is identified: an axiom that they (...) viewed as irrelevant, because it involved disjunction (which was not in their language), is not irrelevant at all.

Experiences, by definition, have phenomenal character. But many experiences have a specific type of phenomenal character: presentational character. While both visual experience and conscious thought make us aware of their objects, only in visual experience do objects seem present before the mind and available for direct access. I argue that Higher-Order Thought (HOT) theories of consciousness have a particularly steep hill to climb in accommodating presentational character.

The question of whether knowledge is definable in terms of belief, which has played an important role in epistemology for the last 50 years, is studied here in the framework of epistemic and doxastic logics. Three notions of definability are considered: explicit definability, implicit definability, and reducibility, where explicit definability is equivalent to the combination of implicit definability and reducibility. It is shown that if knowledge satisfies any set of axioms contained in S5, then it cannot be explicitly defined in (...) terms of belief. S5 knowledge can be implicitly defined by belief, but not reduced to it. On the other hand, S4.4 knowledge and weaker notions of knowledge cannot be implicitly defined by belief, but can be reduced to it by defining knowledge as true belief. It is also shown that S5 knowledge cannot be reduced to belief and justification, provided that there are no axioms that involve both belief and justification. (shrink)

This book analyses tensions that arise between the principles of social justice and the need for cooperation to advance collective goals.

Critical response to John Rawls's The Law of Peopleshas been surprisingly harsh) Most of the complaints centre on Rawls's claim that there are no obligations of distributive justice among nations. Many of Rawls's critics evidently had been hoping for a global application of the difference principle, so that wealthier nations would be bound to assign lexical priority to the development of the poorest nations, or perhaps the primary goods endowment of the poorest citizens of any nation. Their subsequent disappointment reveals (...) that, while the reception of Rawls's political philosophy has been very broad, it has not been especially deep. Rawls has very good reason for denying that there are obligations of distributive justice in an international context. (shrink)

The primary aim of a theory of consciousness is to articulate existence conditions for conscious states, i.e. the conditions under which a mental state is conscious rather than unconscious. There are two main broad approaches: The Higher-Order approach and the First-Order approach. Higher-Order theories claim that a mental state is conscious only if it is the object of a suitable state of higher-order awareness. First-Order theories reject this necessary condition. However, both sides make the following claim: for any mental state (...) M of a subject S, M is conscious if there is something it is like for S to be in M. This is the Nagelian Conception of consciousness. Taking the Nagelian Conception as a starting point, I contend that the best rationalizing explanation for the ways in which Higher-Order and First-Order theorists contribute to their dispute is to see those contributions as consistent responses to two distinct questions.

That Descartes’ God is not a deceiver is amongst the canonical claims of early modern philosophy. The significance of this (purported) fact to the coherence of Descartes’ system is likewise canonical, infused in how we teach and think about the _Meditations_. Though prevalent, both ends of this narrative are suspect. We argue that Descartes’ color eliminativism, when coupled with his analysis of the cognitive structure of our sensory systems, entails that God is a deceiver. It’s doubtful that Descartes recognized this, (...) given his insistence that God is not a deceiver, and the role this plays in his system. But this is a concession Descartes can grant if we are careful about the kind of deception at play—a kind Descartes _does_ recognize, albeit not without some ambiguity. On our story, Descartes’ metaphysics and epistemology are not driven by concerns about deception _per se_, but by concerns about God’s _benevolence_. (shrink)

In this article I argue that the conception of discourse ethics that Jürgen Habermas advances in his seminar paper, ‘Discourse Ethics: Notes on a Program of Philosophical Justification’, is subject to significant revision in later work. The central difference has to do with the status of the universalization principle and its relationship to the ‘rightness’ validity claim. The earlier view is structured by a desire to provide a weak-transcendental defense of the universalization principle. The later revision, however, essentially undercuts the (...) basis of this argument, because it severs the conception of practical discourse from the analysis of speech acts. As a way of responding to the difficulties this creates, I propose a ‘reboot’ of the discourse ethics program. This involves reverting to the earlier, more Durkheimian and less Kantian, formulation of the theory. The result is a program that is no longer encumbered by sterile debates about the correct formulation of the universalization principle, but can plausibly claim to provide insight into the role that language-dependence plays in the development and entrenchment of increasingly pro-social behavior patterns within our institutions.
