Kevin Lynch's books are the classic underpinnings of modern urban planning and design, yet they are only a part of his rich legacy of ideas about human purposes and values in built form. City Sense and City Design brings together Lynch's remaining work, including professional design and planning projects that show how he translated many of his ideas and theories into practice. An invaluable sourcebook of design knowledge, City Sense and City Design completes the record of one of (...) the foremost environmental design theorists of our time and leads to a deeper understanding of his distinctively humanistic philosophy. The editors, both former students of Lynch, provide a cogent summary of his career and of the role he played in shaping and transforming the American urban design profession during the 1950s, the 1960s, and the 1970s. Each of the seven thematic groupings of writings and projects that follow begins with a short introduction explaining their content and their background. The essays in part I focus on the premises of Lynch's work: his novel reading of large-scale built environments and the notion that the design of an urban landscape should be as meaningful and intimate as the natural landscape. In part II, excerpts from Lynch's travel journals reveal his early ideas on how people perceive and interpret their surroundings—ideas that culminated in his seminal work, The Image of the City. This part of the book also presents Lynch's experiments with children and his assessment of environmental-perception research. The examples of both small-scale and large-scale analysis of visual form in part III are followed by three parts on city design. These include Lynch's more theoretical works on complex planning decisions involving both functional (spatial and structural organization) and normative (how the city works in human terms) approaches, articles discussing the principles that guided Lynch's teaching and practice of city design, and descriptions of Lynch's own projects in the Boston area and elsewhere. The book concludes with essays written late in Lynch's career, fantasy pieces describing utopias and offering new design freedoms and scenarios warning of horrifying "cacotopias.". (shrink)

This article discusses a kind of knowledge classifiable as knowledge-wh but which seems to defy analysis in terms of the standard reductive theory of knowledge-wh ascriptions, according to which they are true if and only if one knows that p, where this proposition is an acceptable answer to the wh-question ‘embedded’ in the ascription. Specifically, it is argued that certain cases of knowing what an experience is like resist such treatment. I argue that in some of these cases, one can (...) know that p, where an acceptable answer to the question ‘What’s the experience like?’ is that p, but where one does not know what the experience is like. This could point to the distinctiveness of this sort of knowledge. (shrink)

Willful ignorance is an important concept in criminal law and jurisprudence, though it has not received much discussion in philosophy. When it is mentioned, however, it is regularly assumed to be a kind of self-deception. In this article I will argue that self-deception and willful ignorance are distinct psychological kinds. First, some examples of willful ignorance are presented and discussed, and an analysis of the phenomenon is developed. Then it is shown that current theories of self-deception give no support to (...) the idea that willful ignorance is a kind of self-deception. Afterwards an independent argument is adduced for excluding willful ignorance from this category. The crucial differences between the two phenomena are explored, as are the reasons why they are so easily conflated. (shrink)

We consider emergence from the perspective of dynamics: states of a system evolving with time. We focus on the role of a decomposition of wholes into parts, and attempt to characterize relationships between levels without reference to whether higher-level properties are “novel” or “unexpected.” We offer a classification of different varieties of emergence, with and without new ontological elements at higher levels. -/- Submitted to a volume on Real Patterns (Tyler Milhouse, ed.), to be published by MIT Press.

Shows that the very same asymmetries that arise for intentionally also arise from deciding, desiring, in favor of, opposed to, and advocating. It seems that the phenomenon is not due to anything about the concept of intentional action in particular. Rather, the effects observed for the concept of intentional action should be regarded as just one manifestation of the pervasive impact of moral judgment.

The self-deception debate often appears polarized between those who think that self-deceivers intentionally deceive themselves (‘intentionalists’), and those who think that intentional actions are not significantly involved in the production of self-deceptive beliefs at all. In this paper I develop a middle position between these views, according to which self-deceivers do end up self-deceived as a result of their own intentional actions, but where the intention these actions are done with is not an intention to deceive oneself. This account thus (...) keeps agency at the heart of self-deception, while also avoiding the paradox associated with other agency-centered views. (shrink)

Like William James before him, Huw Price has influentially argued that truth has a normative role to play in our thought and talk. I agree. But Price also thinks that we should regard truth-conceived of as property of our beliefs-as something like a metaphysical myth. Here I disagree. In this paper, I argue that reflection on truth's values pushes us in a slightly different direction, one that opens the door to certain metaphysical possibilities that even a Pricean pragmatist can love.

A prevalent assumption among philosophers who believe that people can intentionally deceive themselves (intentionalists) is that they accomplish this by controlling what evidence they attend to. This article is concerned primarily with the evaluation of this claim, which we may call ‘attentionalism’. According to attentionalism, when one justifiably believes/suspects that not-p but wishes to make oneself believe that p, one may do this by shifting attention away from the considerations supportive of the belief that not-p and onto considerations supportive of (...) the belief that p. The details of this theory are elaborated, its theoretical importance is pointed out, and it is argued that the strategy is supposed to work by leading to the repression of one’s knowledge of the unwelcome considerations. However, I then show that the assumption that this is possible is opposed by the balance of a relevant body of empirical research, namely, the thought-suppression literature, and so intentionalism about self-deception cannot find vindication in the attentional theory.

Some modern cosmological models predict the appearance of Boltzmann Brains: observers who randomly fluctuate out of a thermal bath rather than naturally evolving from a low-entropy Big Bang. A theory in which most observers are of the Boltzmann Brain type is generally thought to be unacceptable, although opinions differ. I argue that such theories are indeed unacceptable: the real problem is with fluctuations into observers who are locally identical to ordinary observers, and their existence cannot be swept under the rug (...) by a choice of probability distributions over observers. The issue is not that the existence of such observers is ruled out by data, but that the theories that predict them are cognitively unstable: they cannot simultaneously be true and justifiably believed.

Alfred Mele's deflationary account of self-deception has frequently been criticised for being unable to explain the “tension” inherent in self-deception. These critics maintain that rival theories can better account for this tension, such as theories which suppose self-deceivers to have contradictory beliefs. However, there are two ways in which the tension idea has been understood. In this article, it is argued that on one such understanding, Mele's deflationism can account for this tension better than its rivals, but only if we (...) reconceptualize the self-deceiver's attitude in terms of unwarranted degrees of conviction rather than unwarranted belief. This new way of viewing the self-deceiver's attitude will be informed by observations on experimental work done on the biasing influence of desire on belief, which suggests that self-deceivers don’t manage to fully convince themselves of what they want to be true. On another way in which this tension has been understood, this account would not manage so well, since on this understanding the self-deceiver is best interpreted as knowing, but wishing to avoid, the truth. However, it is argued that we are under no obligation to account for this since it is a characteristic of a different phenomenon than self-deception, namely, escapism. (shrink)

Stubborn belief, like self-deception, is a species of motivated irrationality. The nature of stubborn belief, however, has not been investigated by philosophers, and it is something that poses a challenge to some prominent accounts of self-deception. In this paper, I argue that the case of stubborn belief constitutes a counterexample to Alfred Mele’s proposed set of sufficient conditions for self-deception, and I attempt to distinguish between the two. The recognition of this phenomenon should force an amendment in this account, and (...) should also make a Mele-style deflationist think more carefully about the kinds of motivational factors operating in self-deception.

Many philosophers take understanding to be a distinctive kind of knowledge that involves grasping dependency relations; moreover, they hold it to be particularly valuable. This paper aims to investigate and address two well-known puzzles that arise from this conception: (1) the nature of understanding itself—in particular, the nature of “grasping”; (2) the source of understanding’s distinctive value. In what follows, I’ll argue that we can shed light on both puzzles by recognizing first, the importance of the distinction between the act (...) of coming to understand and the state of understanding; and second, that coming to understand is a creative act.

It is commonplace in discussions of modern cosmology to assert that the early universe began in a special state. Conventionally, cosmologists characterize this fine-tuning in terms of the horizon and flatness problems. I argue that the fine-tuning is real, but these problems aren't the best way to think about it: causal disconnection of separated regions isn't the real problem, and flatness isn't a problem at all. Fine-tuning is better understood in terms of a measure on the space of trajectories: given (...) reasonable conditions in the late universe, the fraction of cosmological histories that were smooth at early times is incredibly tiny. This discussion helps clarify what is required by a complete theory of cosmological initial conditions. (shrink)

Immanuel Kant’s moral philosophy is organized around an exclusive disjunction of dignity or price, equality or equivalence. In his 1797 Doctrine of Right, however, Kant places enslaved black people on the wrong side of this disjunction when he speculates that their status as currency may offer insight into the origins of money. Recent work in black studies has begun to speculate on the link between blackness and money in modernity, and this paper draws attention to Kant’s role as an unlikely (...) and unwitting precursor for monetary theories of blackness. Precisely in his attempt to secure the priceless and unconditional character of freedom and dignity, it argues, Kant ends up demonstrating the positional value of both. (shrink)

We study the question of how to decompose Hilbert space into a preferred tensor-product factorization without any pre-existing structure other than a Hamiltonian operator, in particular the case of a bipartite decomposition into "system" and "environment." Such a decomposition can be defined by looking for subsystems that exhibit quasi-classical behavior. The correct decomposition is one in which pointer states of the system are relatively robust against environmental monitoring (their entanglement with the environment does not continually and dramatically increase) and remain (...) localized around approximately-classical trajectories. We present an in-principle algorithm for finding such a decomposition by minimizing a combination of entanglement growth and internal spreading of the system. Both of these properties are related to locality in different ways. This formalism could be relevant to the emergence of spacetime from quantum entanglement. (shrink)

Selective scientific realists disagree on which theoretical posits should be regarded as essential to the empirical success of a scientific theory. A satisfactory account of essentialness will show that the (approximate) truth of the selected posits adequately explains the success of the theory. Therefore, (a) the essential elements must be discernible prospectively; (b) there cannot be a priori criteria regarding which type of posit is essential; and (c) the overall success of a theory, or ‘cluster’ of propositions, not only individual (...) derivations, should be explicable. Given these desiderata, I propose a “unification criterion” for identifying essential elements. (shrink)

In this essay, I examine four different reasons for thinking that political dissent has epistemic value. The realization of this epistemic value hinges in part on what I’ll loosely call the epistemic environment, or the environment in which individuals come to believe, reason, inquire, and debate. In particular, to the degree that our social practices encourage and even embody an attitude of epistemic arrogance, the epistemic value of dissent will be difficult to realize. Ironically, it is precisely then that dissent (...) is most often needed. (shrink)

The notion of basic action has recently come under attack based on the idea that any putative basic action can always be divided into more basic sub-actions. In this paper it is argued that this criticism ignores a key aspect of the idea of basic action, namely, the ‘anything else’ part of the idea that basic actions are not done by doing anything else. This aspect is clarified, and it is argued that doing the sub-actions of which a putative basic (...) action consists does not amount to doing something different from doing that putative basic action.

On one popular view, the general covariance of gravity implies that change is relational in a strong sense, such that all it is for a physical degree of freedom to change is for it to vary with regard to a second physical degree of freedom. At a quantum level, this view of change as relative variation leads to a fundamentally timeless formalism for quantum gravity. Here, we will show how one may avoid this acute ‘problem of time’. Under our view, (...) duration is still regarded as relative, but temporal succession is taken to be absolute. Following our approach, which is presented in more formal terms in, it is possible to conceive of a genuinely dynamical theory of quantum gravity within which time, in a substantive sense, remains. 1 Introduction1.1 The problem of time1.2 Our solution2 Understanding Symmetry2.1 Mechanics and representation2.2 Freedom by degrees2.3 Voluntary redundancy3 Understanding Time3.1 Change and order3.2 Quantization and succession4 Time and Gravitation4.1 The two faces of classical gravity4.2 Retaining succession in quantum gravity5 Discussion5.1 Related arguments5.2 Concluding remarks.

The Principle of Sufficient Reason (PSR) holds that, for everything that exists or occurs or holds true, there is a reason why that is the case. I consider three possible ways of relating physics to the PSR: past states as reasons for present states, reasons why the laws of physics take the form that they do, and reasons why there is anything at all. In each case I suggest that the PSR is not the best way of thinking about how (...) and why physics works. -/- Invited reflection for The Principle of Sufficient Reason (Oxford Philosophical Concepts), Eds.

Cosmological models that invoke a multiverse - a collection of unobservable regions of space where conditions are very different from the region around us - are controversial, on the grounds that unobservable phenomena shouldn't play a crucial role in legitimate scientific theories. I argue that the way we evaluate multiverse models is precisely the same as the way we evaluate any other models, on the basis of abduction, Bayesian inference, and empirical success. There is no scientifically respectable way to do (...) cosmology without taking into account different possibilities for what the universe might be like outside our horizon. Multiverse theories are utterly conventionally scientific, even if evaluating them can be difficult in practice. (shrink)

Although Alston believed epistemically circular arguments were able to justify their conclusions, he was also disquieted by them. We will argue that Alston was right to be disquieted. We explain Alston’s view of epistemic circularity, the considerations that led him to accept it, and the purposes he thought epistemically circular arguments could serve. We then build on some of Alston’s remarks and introduce further limits to the usefulness of such arguments and introduce a new problem that stems from those limits. (...) The upshot is that adopting Alston’s view that epistemically circular arguments can be used to justify their conclusions is more costly than even he thought. (shrink)

Economic policy evaluations require social welfare functions for variable-size populations. Two important candidates are critical-level generalized utilitarianism (CLGU) and rank-discounted critical-level generalized utilitarianism, which was recently characterized by Asheim and Zuber (2014) (AZ). AZ introduce a novel axiom, existence of egalitarian equivalence (EEE). First, we show that, under some uncontroversial criteria for a plausible social welfare relation, EEE suffices to rule out the Repugnant Conclusion of population ethics (without AZ’s other novel axioms). Second, we provide a new characterization of CLGU: (...) AZ’s set of axioms is equivalent to CLGU when EEE is replaced by the axiom same-number independence. (shrink)

This paper investigates whether we can know how to do basic actions, from the perspective according to which knowing how to do something requires knowledge of a way to do it. A key argument from this perspective against basic know-how is examined and is found to be unsound, involving the false premise that there are no ways of doing basic actions. However, a new argument along similar lines is then developed, which contends that there are no ways of doing basic (...) actions in any sense that matters for acquiring knowledge-how. This requires coming to a deeper understanding of ways of doing things than has hitherto been sought, which should be useful for further theorizing in this area. It is concluded that analyses of knowing-how in terms of knowledge of ways are inconsistent with the common assumption that there is basic know-how. (shrink)

According to Russellianism (or Millianism), the two sentences ‘Ralph believes George Eliot is a novelist’ and ‘Ralph believes Mary Ann Evans is a novelist’ cannot diverge in truth-value, since they express the same proposition. The problem for the Russellian (or Millian) is that a puzzle of Kaplan’s seems to show that they can diverge in truth-value and that therefore, since the Russellian holds that they express the same proposition, the Russellian view is contradictory. I argue that the standard Russellian appeal (...) to “ways of thinking” or “propositional guises” is not necessary to solve the puzzle. Rather than this retrograde concession to Fregeanism, appeal should be made to second-order belief. The puzzle is solved, and the contradiction avoided, by maintaining that both sentences are indeed true in addition to the sentence ‘Ralph (mistakenly) believes that he does not believe Mary Ann Evans/George Eliot is a novelist’.

Drawing on Roberto Esposito’s conceptualization of ‘affirmative biopolitics’, this article examines the relationship between bedbugs and humans in the Glasgow neighbourhood of Govanhill. Through an analysis of ethnographic field notes and interviews with people who live in the area, this article traces their experiences from first encounters. The trajectory of this experience shows a shift from a desire to immunize their homes through total annihilation of the creatures to the more pragmatic position of learning how to live with them through (...) an orientation toward ‘shared vulnerability’. This case study raises interesting questions for biopolitical theory: how can we conceive of affirmative biopolitics when the limitations of species being are evident, and is it possible to conceive of a multi or even interspecies munus or obligation?

Physical boundaries and the earliest topologists. Topology has a relatively short history; but its 19th century roots are embedded in philosophical problems about the nature of extended substances and their boundaries which go back to Zeno and Aristotle. Although it seems that there have always been philosophers interested in these matters, questions about the boundaries of three-dimensional objects were closest to center stage during the later medieval and modern periods. Are the boundaries of an object actually existing, less-than-three-dimensional parts of (...) the object—that is, are solids bounded by two-dimensional surfaces, surfaces by one-dimensional “edges” or “physical lines”, edges by dimensionless “simples”? If not, how does a perfectly spherical object manage to touch a perfectly flat object—what part of the sphere is in immediate contact with the plane, if the sphere has no unextended parts? But if such parts be admitted, are we not then saddled with “actual infinities” of simples, lines, and surfaces spread throughout each continuous object—the boundaries of all the object’s internal parts? Does it help to say that these internal boundaries exist only “potentially”? (shrink)

According to the Public Justification Principle, legitimate laws must be justifiable to all reasonable citizens. Proponents of this principle assume that its satisfaction requires speakers to offer justifications that are representable as arguments that feature premises which reasonable listeners would accept. I develop the concept of dark knowledge to show that this assumption is false. Laws are often justified on the basis of premises that many reasonable listeners know, even though they would reject these premises on the basis of the (...) further considerations that speakers implicitly rely on for their support. Accommodating the fact of dark knowledge requires us to consider the civic virtue of speakers to be more important for public justification than the acceptability of their arguments to reasonable citizens. I sketch an alternative conception of public justification that incorporates these results and argue that it provides a rationale for ignoring the otherwise sound contributions of some participants in political deliberation.

In his new book, Knowledge: The Philosophical Quest in History, Steve Fuller returns to core themes of his program of social epistemology that he first outlined in his 1988 book, Social Epistemology. He develops a new, unorthodox theology and philosophy building upon his testimony in Kitzmiller v. Dover Area School District in defense of intelligent design, leading to a call for maximal human experimentation. Beginning from the theological premise rooted in the Abrahamic religious tradition that we are created in the (...) image of God, Fuller argues that the spark of the divine within us distinguishes us from animals. I argue that Fuller’s recent work takes us away from key insights of his original work. In contrast, I advocate for a program of social epistemology rooted in evolutionary science rather than intelligent design, emphasize a precautionary and ecological approach rather than a proactionary approach that favors risky human experimentation, and attend to our material and sociological embeddedness rather than a transhumanist repudiation of the body.

We have a much better understanding of physics than we do of consciousness. I consider ways in which intrinsically mental aspects of fundamental ontology might induce modifications of the known laws of physics, or whether they could be relevant to accounting for consciousness if no such modifications exist.

Quine introduced a famous distinction between the ‘notional’ sense and the ‘relational’ sense of certain attitude verbs. The distinction is both intuitive and sound but is often conflated with another distinction Quine draws between ‘dyadic’ and ‘triadic’ (or higher degree) attitudes. I argue that this conflation is largely responsible for the mistaken view that Quine’s account of attitudes is undermined by the problem of the ‘exportation’ of singular terms within attitude contexts. Quine’s system is also supposed to suffer from the (...) problem of ‘suspended judgement with continued belief’. I argue that this criticism fails to take account of a crucial presupposition of Quine’s about the connection between thought and language. The aim of the paper is to defend the spirit of Quine’s account of attitudes by offering solutions to these two problems. (shrink)

I defend the extremist position that the fundamental ontology of the world consists of a vector in Hilbert space evolving according to the Schrödinger equation. The laws of physics are determined solely by the energy eigenspectrum of the Hamiltonian. The structure of our observed world, including space and fields living within it, should arise as a higher-level emergent description. I sketch how this might come about, although much work remains to be done.

Emotional hardcore and other music genres featuring screamed vocals are puzzling for the appreciator. The typical fan attaches appreciative value to musical screams of emotional pain, all the while acknowledging it would be inappropriate to hold similar attitudes towards their sonically similar everyday counterpart: actual human screaming. Call this the screamed vocals problem. To solve the problem, I argue we must attend to the anti-sublimating aims that get expressed in the emotional hardcore vocalist’s choice to scream the lyrics. Screamed vocals (...) help us see the value in rejecting (a) restrictive social norms of emotional expressiveness and (b) restrictive artistic norms about how one ought to express or represent pain in art—namely that if one is going to do so, one must ensure the pain has been ‘beautified’. In developing this second point, I argue that emotional hardcore is well-suited (although not individually so) for putting pressure on longstanding views in the history of aesthetics about the formal relationship between art and human pain.

A distinction can be made between those who think that self-deception is frequently intentional and those who don’t. I argue that the idea that self-deception has to be intentional can be partly traced to a particular invalid method for analyzing reflexive expressions of the form ‘Ving oneself’ (where V stands for a verb). However, I take the question of whether intentional self-deception is possible to be intrinsically interesting, and investigate the prospects for such an alleged possibility. Various potential strategies of (...) intentional self-deception are examined in relation to Alfred Mele’s suggestion that doing something intentionally implies doing it knowingly. It is suggested that the best prospects for an intentionalist theory of self-deception lie with a strategy involving the control of attention. (shrink)

It seems natural to ask why the universe exists at all. Modern physics suggests that the universe can exist all by itself as a self-contained system, without anything external to create or sustain it. But there might not be an absolute answer to why it exists. I argue that any attempt to account for the existence of something rather than nothing must ultimately bottom out in a set of brute facts; the universe simply is, without ultimate cause or explanation.

The identity theory’s rise to prominence in analytic philosophy of mind during the late 1950s and early 1960s is widely seen as a watershed in the development of physicalism, in the sense that whereas logical behaviourism proposed analytic and a priori ascertainable identities between the meanings of mental and physical-behavioural concepts, the identity theory proposed synthetic and a posteriori knowable identities between mental and physical properties. While this watershed does exist, the standard account of it is misleading, as it is (...) founded in erroneous intensional misreadings of the logical positivists’—especially Carnap’s—extensional notions of translation and meaning, as well as misinterpretations of the positivists’ shift from the strong thesis of translation-physicalism to the weaker and more liberal notion of reduction-physicalism that occurred in the Unity of Science programme. After setting the historical record straight, the essay traces the first truly modern identity theory to Schlick’s pre-positivist views circa 1920 and goes on to explore its further development in Feigl, arguing that the fundamental difference between the Schlick-Feigl identity theory and the more familiar and influential Place-Smart-Armstrong identity theory has resurfaced in the deep and seemingly unbridgeable gulf in contemporary philosophy of consciousness between inflationary mentalism and deflationary physicalism.

According to the pragmatic hypothesis testing theory, how much evidence we require before we believe something varies depending on the expected costs of falsely believing and disbelieving it. This theory has been used in the self-deception debate to explain our tendencies towards self-deceptive belief formation. This article argues that the application of this theory in the self-deception debate has overlooked the distinction between belief and acceptance, and that the theory in all likelihood models acceptance rather than belief, in which case (...) it is probably not relevant to the explanation of self-deception. It is suggested, however, that doxastic error costs might be relevant to explaining some types of self-deception, though they feature in an evolutionary explanation of it rather than a psychological one.

Propositionalism is the view that intentional attitudes, such as belief, are relations to propositions. Propositionalists argue that propositionalism follows from the intuitive validity of certain kinds of inferences involving attitude reports. Jubien (2001) argues powerfully against propositions and sketches some interesting positive proposals, based on Russell’s multiple relation theory of judgment, about how to accommodate “propositional phenomena” without appeal to propositions. This paper argues that none of Jubien’s proposals succeeds in accommodating an important range of propositional phenomena, such as the (...) aforementioned validity of attitude-report inferences. It then shows that the notion of a predication act-type, which remains importantly Russellian in spirit, is sufficient to explain the range of propositional phenomena in question, in particular the validity of attitude-report inferences. The paper concludes with a discussion of whether predication act-types are really just propositions by another name. (shrink)

A crucial part of the contemporary interest in logicism in the philosophy of mathematics resides in its idea that arithmetical knowledge may be based on logical knowledge. Here an implementation of this idea is considered that holds that knowledge of arithmetical principles may be based on two things: (i) knowledge of logical principles and (ii) knowledge that the arithmetical principles are representable in the logical principles. The notions of representation considered here are related to theory-based and structure-based notions of representation (...) from contemporary mathematical logic. It is argued that the theory-based versions of such logicism are either too liberal (the plethora problem) or are committed to intuitively incorrect closure conditions (the consistency problem). Structure-based versions must on the other hand respond to a charge of begging the question (the circularity problem) or explain how one may have a knowledge of structure in advance of a knowledge of axioms (the signature problem). This discussion is significant because it gives us a better idea of what a notion of representation must look like if it is to aid in realizing some of the traditional epistemic aims of logicism in the philosophy of mathematics.

We provide a derivation of the Born Rule in the context of the Everett (Many-Worlds) approach to quantum mechanics. Our argument is based on the idea of self-locating uncertainty: in the period between the wave function branching via decoherence and an observer registering the outcome of the measurement, that observer can know the state of the universe precisely without knowing which branch they are on. We show that there is a uniquely rational way to apportion credence in such cases, which (...) leads directly to the Born Rule. Our analysis generalizes straightforwardly to cases of combined classical and quantum self-locating uncertainty, as in the cosmological multiverse. (shrink)

Though the psychoanalytic method of interpretation is seen by psychoanalysts as a reliable scientific tool for investigating the unconscious mind, its reputation has long been marred by what’s known as the consensus problem: where different analysts fail to reach agreement when they interpret the same phenomena. This has long been thought, by both practitioners and observers of psychoanalysis, to undermine its claim to scientific status. The causes of this problem, however, are dimly understood. In this paper I attempt to illuminate (...) one important cause of the consensus problem by investigating the role which reliance on ‘associative evidence’ has in generating consensus failures. Various options for overcoming the difficulties with this form of clinical evidence are then examined. It is argued that these problems can be mitigated by the notion of overall associative fit, though they are exacerbated by certain loose standards used for what counts as acceptable associative evidence. The possibility of using more rigorous standards is discussed. (shrink)

Effective Field Theory (EFT) is the successful paradigm underlying modern theoretical physics, including the "Core Theory" of the Standard Model of particle physics plus Einstein's general relativity. I will argue that EFT grants us a unique insight: each EFT model comes with a built-in specification of its domain of applicability. Hence, once a model is tested within some domain (of energies and interaction strengths), we can be confident that it will continue to be accurate within that domain. Currently, the Core (...) Theory has been tested in regimes that include all of the energy scales relevant to the physics of everyday life (biology, chemistry, technology, etc.). Therefore, we have reason to be confident that the laws of physics underlying the phenomena of everyday life are completely known. (shrink)

Variable-Value axiologies avoid Parfit’s Repugnant Conclusion while satisfying some weak instances of the Mere Addition principle. We apply calibration methods to two leading members of the family of Variable-Value views conditional upon: first, a very weak instance of Mere Addition and, second, some plausible empirical assumptions about the size and welfare of the intertemporal world population. We find that such facts calibrate these two Variable-Value views to be nearly totalist, and therefore imply conclusions that should seem repugnant to anyone who (...) opposes Total Utilitarianism only due to the Repugnant Conclusion.

Political scientists' failure to pay careful attention to the content (as opposed to the operationalization) of their chosen definition of 'democracy' can make them liable to draw invalid inferences from their empirical research. With this problem in mind, we argue for the following proposition: if one wishes to conduct empirical research that contributes to an existing conversation about democracy, then one must choose a definition of 'democracy' that picks out the topic of that conversation as opposed to some other (perhaps (...) nearby) topic of conversation. We show that, as a practical matter, one of the most effective methods for preserving "topic continuity" is to choose a definition of `democracy' that concurs with prevailing judgments about how to classify particular regimes, emphasizing the superiority (in this regard) of judgments about stylized hypothetical scenarios as opposed to judgments about the actual regimes we observe in our datasets.

I ask whether what we know about the universe from modern physics and cosmology, including fine-tuning, provides compelling evidence for the existence of God, and answer largely in the negative.

We study the conservation of energy, or lack thereof, when measurements are performed in quantum mechanics. The expectation value of the Hamiltonian of a system changes when wave functions collapse in accordance with the standard textbook treatment of quantum measurement, but one might imagine that the change in energy is compensated by the measuring apparatus or environment. We show that this is not true; the change in the energy of a state after measurement can be arbitrarily large, independent of the (...) physical measurement process. In Everettian quantum theory, while the expectation value of the Hamiltonian is conserved for the wave function of the universe, it is not constant within individual worlds. It should therefore be possible to experimentally measure violations of conservation of energy, and we suggest an experimental protocol for doing so. (shrink)

The Pneumatist school of medicine has the distinction of being the only medical school in antiquity named for a belief in a part of a human being. Unlike the Herophileans or the Asclepiadeans, their name does not pick out the founder of the school. Unlike the Dogmatists, Empiricists, or Methodists, their name does not pick out a specific approach to medicine. Instead, the name picks out a belief: the fact that pneuma is of paramount importance, both for explaining health and (...) disease, and for determining treatments for the healthy and sick. In this paper, we re-examine what our sources say about the pneuma of the Pneumatists in order to understand what these physicians thought it was and how it shaped their views on physiology, diagnosis and treatment.
