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)

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)

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. I suggest that our current knowledge of physics should make us skeptical of hypothetical modifications of the known rules, and that without such modifications it’s hard to imagine how intrinsically mental aspects could (...) play a useful explanatory role.

The production of scientific instruments in America was neither a postwar phenomenon nor dramatically different from that of several other developed countries. It did, however, undergo a step-change in direction, size and style during and after the war. The American scientific instrument industry after 1945 was intimately dependent on, and shaped by, prior American and European experience. This was true of the specific genres of instrument produced commercially; to links between industry and science; and, just as importantly, to manufacturing practices (...) and cultures. I will argue that, despite the new types of instrument commercialized after the war, this historical continuity of links with science and scientists guided and constrained the design and manufacture of these products. Nevertheless, new designers, manufacturers and customers gradually transformed the culture of scientific instruments in the second half of the century. -/- This chapter deals with a subset of the American instrument industry, namely the measuring and monitoring instruments manufactured for scientific use. Even with the specification of ‘scientific’ instruments, however, these borders are rather artificial and unclear: instrument making from the seventeenth through the twentieth century has generally involved the fabrication of both standard products and custom-made devices for scientific use.2 In this context of sales quantities, ‘scientific’ instruments have often been defined as low-volume, special-order or custom devices. In a similar vein, ‘scientific’ instruments were commonly distinguished from ‘production’ instruments by context of usage, namely their very absence from – and indeed irrelevance to – production environments. This demarcation according to customer and environment was mirrored in at least one furth er respect: the training of their users. The classification into ‘scientific’ and ‘engineering’ applications was as fluid as the relationship between American universities and technical industries themselves.Despite these complementary definitions, the notion of the ‘scientific instrument’ was beginning to prove inadequate even at the turn of the twentieth century, and dramatically so when discussing the post-Second World War period. Definitions altered qualitatively after the Second World War in at least three further ways: (a) new genres of device altered the scope of the scientific instrument; (b) the contribution of State and military sponsorship of new forms of instrument became significant; and, (c) the postwar demand for specialist instruments increased rapidly, owing to wartime innovation, new applications and new customers. I will explore the evolution of instrument manufacturing in this changing context of new technology, funding, development and markets. (shrink)

This chapter offers a general outline of Schopenhauer’s peculiarly named concept of the 'acquired character’ and explains its basic function in his ethical thought. For Schopenhauer, a person of acquired character is someone who knows the ways of acting (Handlungsweise) that are most expressive of their individuality and who allows that self-knowledge to structure their practical and emotional life. In keeping with certain elements of his psychological determinism, acquired character is not the acquisition of a ‘new’ character; rather, it is (...) the acquisition of self-knowledge of one’s essentially fixed empirical character. It is part of the argument of this chapter that by introducing the acquired character into his reflections on human action and agency Schopenhauer weaves a certain view of individual flourishing (eudaimonia) into his ethics. There are two central ingredients of Schopenhauer’s conception of eudaimonia, and both are linked to the acquired character. The first is self-knowledge; the second is a sense of personal autonomy that follows in the wake of the first. The chapter ends with a brief attempt to connect Schopenhauer’s concept of acquired character to contemporary debates in ethics concerning autonomy, practical identity, and what some call the ‘normative significance of self’.

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)

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)

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’.

Our culture is dominated by digital documents in ways that are easy to overlook. These documents have changed our worldviews about science and have raised our expectations of them as tools for knowledge justification. This article explores the complexities surrounding the digital document by revisiting Michael Polanyi’s theory of tacit knowledge—the idea that “we can know more than we can tell.” The theory presents to us a dilemma: if we can know more than we can tell, then this means that (...) the communication of science via the document as a primary form of telling will always be incomplete. This dilemma presents significant challenges to the open science movement. (shrink)

This paper explores the idea that many “simple minded” invertebrates are “natural zombies” in that they utilize their senses in intelligent ways, but without phenomenal awareness. The discussion considers how “first-order” representationalist theories of consciousness meet the explanatory challenge posed by blindsight. It would be an advantage of first-order representationalism, over higher-order versions, if it does not rule out consciousness in most non-human animals. However, it is argued that a first-order representationalism which adequately accounts for blindsight also implies that most (...) non-mammals are not conscious. The example of the honey bee is used to illuminate these claims. Although there is some reason to think that bees have simple beliefs and desires, nevertheless, their visually-mediated cognizing is comparable to that of an animal with blindsight. There is also reason to think that the study of blindsight can also help determine how consciousness is distributed in the animal world. (shrink)

In his monograph *Happiness for Humans*, Daniel C. Russell argues that someone’s happiness is constituted by her virtuous engagement in a certain special sort of activity, which he calls *embodied activity*. An embodied activity is one which depends for its identity on things which lie outside of the agent’s control. What this means is that whether or not it is possible for the activity to continue is not completely up to the agent. A motivating example is my activity of living (...) alongside my spouse. Whether or not it is possible for this activity to continue is not entirely within my control, because my spouse might die, or otherwise become unavailable to me. To defend the view that it’s embodied activities which are constitutive of happiness, Russell defends what he calls the *embodied conception* of the self. This is the view that the boundaries of the self whose happiness is at stake include all the constitutive parts of our embodied activities. In response, I provide two arguments. Firstly, I show that while Russell makes a good case for the relevance of embodied *activities* to happiness, he doesn’t establish that we must adopt the embodied conception of the *self* in order to obtain those insights. Secondly, I argue that to draw the boundaries of the self in accordance with the embodied conception involves forming beliefs in a way that is not epistemically responsible. In making this argument I rely on the claim that there is a strong, particular sense in which other people are unknowable to us, a claim which is developed in the fiction of Haruki Murakami.

For those familiar with Machiavelli’s texts, Foucault’s interpretation of Macchiavelli in his 1978 lecture series Sécurité, Territoire, Population1 is surprising. Although Machiavelli figures prominently in five of the thirteen lectures,2 Foucault treats Machiavelli as if he were the author of only one book—The Prince—and his reading treats this complex text as if it covered only one topic: how to guarantee the security of the Prince. Clearly Foucault did not intend his interpretation of Machiavelli as a close exegesis. Other discussions of (...) Foucault’s treatment of Machiavelli have acknowledged the role Machiavelli plays in these lectures and even note the inadequacy of the interpretation given by Foucault, but most commentators do not pursue Foucault’s reading further.3 This investigation is not concerned with whether Foucault got Machiavelli right. Rather, Foucault’s reading of Machiavelli is noteworthy because it is partial and incomplete in a way reminiscent of Foucault’s reading of Hobbes in, Il faut défendre la société. This fragmentary character of Foucault’s inscription of Machiavelli as a forerunner of the history of biopolitique allows an innovative reading of the Florentine that connects Machiavelli’s thinking, however indirectly, on a trajectory that encounters, for instance, Foucault’s analysis of populations, the police state, and even his reading of liberalism during the 1978-­‐ 1979 lectures. My argument here is that the specific way Foucault’s inscribes Machiavelli in the history of gouvernementalité, while seeming to reject him, in fact acts to resuscitate, and thereby relay, a reading of Machiavelli as a thinker who articulates encounters among political practices engaged within a horizon of radical immanence.

This paper examines the notion of the biopolitical body from the standpoint of Foucault’s logic of the security mechanism and the history he tells of vaccine technology. It then investigates how the increasing importance of the genetic code for determining the meaning and limits of the human in the field of 20th century cell biology has been a cause for ongoing transformation in the practices that currently extend vaccine research and development. I argue that these transformations mark the emergence of (...) a new kind of medical subject – the stabilized and infinitely reproducible human cell line – and that the practices and markets exploiting this new form of organism have had a destabilizing effect on the very biopolitical structures that engendered them and, in fact, mark a new way of conceiving the possibilities of cellular life. I call these new ways of organizing power that intervene in the logic of the security measure by mediating the relationship between populations and persons the microbiopolitical. (shrink)

The practice of taking hand-written notes in lectures has been rediscovered recently because of several studies on its learning efficacy in the mainstream media. Students are enjoined to ditch their laptops and return to pen and paper. Such arguments presuppose that notes are taken in order to be revisited after the lecture. Learning is seen to happen only after the event. We argue instead that student’s note-taking is an educational practice worthy in itself as a way to relate to the (...) live event of the lecture. We adopt a phenomenological approach inspired by Vilém Flusser’s phenomenology of gestures, which assumes that a gesture like note-taking is always an event of thinking with media in which a certain freedom is expressed. But Flusser’s description of note-taking focusses on the individual note-taker. What about students’ note-taking in a lecture hall as a collective gesture? Nietzsche considered note-taking ‘mechanical,’ as if students were automatons who mindlessly transcribed a verbal flow, while Benjamin considered it an inaesthetic gesture: at best, boring; at worst, ‘painful to watch.’ In contrast, we argue that the educational potentiality of note-taking—or better, note-making—can be grasped only if we account for its mediaticity (as writing that displaces the voice), together with but distinct from its political potentiality as a collective mediality (as a ‘means without end’). Note-taking enables us to see how collective thinking emerges in the lecture, a kind of thinking that belongs neither to the lecturer nor the student, but emerges in the relation of attention established between the lecturer, students and their object of thought.

In a recent article [AJP, 2013], Saul Smilansky argues that our own existence is regrettable and that we should prefer not to have existed at all. I show why Smilansky's argument is fallacious, if we understand terms like ‘regrettable’ and ‘prefer’ in a straightforward non-deviant way.

Many philosophers have held that we cannot say what it is like to be a bat as they present a fundamentally alien form of life. Another view held by some philosophers, bat scientists, and even many laypersons is that echolocation is, somehow, at least in part, a kind of visual experience. Either way, bat echolocation is taken to be something very mysterious and exotic. I utilize empirical and intuitive considerations to support an alternative view making a much more mundane contention (...) about bat phenomenology: echolocatory experience probably just has an auditory character. These points also call for further reflection on our intuitions about animal consciousness and standard arguments for the explanatory gap. (shrink)

A longstanding issue in attempts to understand the Everett (Many-Worlds) approach to quantum mechanics is the origin of the Born rule: why is the probability given by the square of the amplitude? Following Vaidman, we note that observers are in a position of self-locating uncertainty during the period between the branches of the wave function splitting via decoherence and the observer registering the outcome of the measurement. In this period it is tempting to regard each branch as equiprobable, but we (...) argue that the temptation should be resisted. Applying lessons from this analysis, we demonstrate (using methods similar to those of Zurek's envariance-based derivation) that the Born rule is the uniquely rational way of apportioning credence in Everettian quantum mechanics. In doing so, we rely on a single key principle: changes purely to the environment do not affect the probabilities one ought to assign to measurement outcomes in a local subsystem. We arrive at a method for assigning probabilities in cases that involve both classical and quantum self-locating uncertainty. This method provides unique answers to quantum Sleeping Beauty problems, as well as a well-defined procedure for calculating probabilities in quantum cosmological multiverses with multiple similar observers.

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 42.1 (2004) 113-115 [Access article in PDF] Wilhelm Dilthey. The Formation of the Historical World in the Human Sciences. Edited with an Introduction by Rudolf A. Makkreel and Frithjof Rodi. Princeton: Princeton University Press, 2002. Pp xiii + 399. Cloth $55.00. The first complete English translation of Wilhelm Dilthey's (1833-1911) most important mature work—a seminal work for hermeneutics, phenomenology, critical theory, and the (...) philosophy of history and the human sciences—is to be greatly welcomed. This excellent translation conveys the subtlety and richness of Dilthey's German. Its innovative translations of key terms will provide renewed stimulus to interpreting Dilthey's works.This edition includes Dilthey's investigation of the structures of consciousness in his three preliminary "Studies toward the Foundation of the Human Sciences," his exploration [End Page 113] of the import of the productive systems of historical life for knowledge in The Formation of the Historical World in the Human Sciences, and his final and perhaps best formulation of hermeneutics in "The Understanding of Other Persons and Their Manifestations of Life."Although Carnap and others utilized the word Aufbau in the sense of epistemic "construction," Makkreel and Rodi clarify how Dilthey used it in the sense of "formation." The formation of the historical world refers to its articulation in the human sciences which themselves theoretically reflect this historical world (GSW3: 1). They also argue that Dilthey's theory of the human sciences is not merely an epistemology (Erkenntnistheorie), but a theory of knowledge (Theorie des Wissens) that relates knowing to its context. Whereas epistemology seeks to establish the foundations of conceptual cognition (Erkenntnis), Dilthey places the epistemology of the human sciences within a larger context of the knowledge (Wissen) embodied in social practices and historical forms of life. Knowledge encompasses not only the conceptual cognition of reality, but also the values and purposes established about it.Dilthey accordingly situated the human sciences, which are determined by their respective object and how the object is given (SW3: 38), in relation to a pretheoretical life-nexus and its forms of elementary or ordinary understanding. These are tied up with the temporality, historicity, and structures of social life; with an epochal "objective spirit." Objective spirit indicates the ways in which the past has been objectified and continues to shape contemporary practices and it is analyzed in the human sciences as cultural systems and the external organization of society. A significant characteristic of the Formation is the development of the notion of "productive system or nexus." This new translation of Wirkungszusammenhang suggests a historical efficacy or productivity prior to any analysis of it as either causal or teleological (SW3: 4).The human sciences include the study of dynamic interconnected systems that articulate the intersection of meaning, value, purpose, and force. Dilthey interpreted these temporally, such that meaning primarily concerns how humans are determined by their past, value is based on their present feeling of life, and purpose is projective striving into the future in the face of productive forces (Kräfte) which cannot always be predicted or controlled.For Dilthey, understanding (verstehen) is intrinsically interpretive. Humans can cognize themselves and others only indirectly (SW3: 108), since we are conscious and reflective beings who are bound to the facticity of our bodies and world. Given that we know ourselves and others primarily through actions, life-expressions, and their effects—rather than through introspection or intuition—and that everyday understanding can face breakdowns and what seems distant or strange, elementary understanding leads to higher forms of understanding and interpretation; i.e., hermeneutics. Dilthey's project of a critique of historical reason proceeds from the context of life in all of its complexity and concreteness to the conceptual cognition of the sciences and, finally, to reflective awareness (Besinnung). This reflection is made possible by the prereflective reflexivity (Innesein or Innewerden) of the human subject and, with its double meaning of "sense" (Sinn) as meaning and bodily awareness, constitutes the basic movement of Dilthey's thought.Understanding provides more than scientific access to...

The use of mobile devices has generated a new way of communication by using unique abbreviations and grammatical shortcuts. This method of communicating has been commonly used by teenagers to socialize with other people in their generation. The use of these texts has alarmed parents and teachers. This study was conducted to discover the correlation of this method of communication called “Tech Speak” to a student's English proficiency. The researcher has surveyed grade 10 students, that has a total of 28 (...) students, at Santiago National high school. The researcher used 10 words that are commonly misspelled as a parameter of the spelling test to measure the proficiency of both techspeak and non-techspeak students. The results yield an average of 8 and 7.7, thus making the students using Tech Speak more proficient in spelling than the students that are categorized as non-techspeak. The findings have led the researchers to conclude that the use of techspeak has no negative effects but rather it improves the student’s spelling proficiency. (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)

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 they must ensure the pain has been ‘beautified’. In developing this second point I argue that emotional hardcore is well-suited (though not individually so) for putting pressure on longstanding views in the history of aesthetics about the formal relationship between art and human pain.

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.

Reichenbach's 'principle of the common cause' is a foundational assumption of some important recent contributions to quantitative social science methodology but no similar principle appears in econometrics. Reiss (2005) has argued that the principle is necessary for instrumental variables methods in econometrics, and Pearl (2009) builds a framework using it that he proposes as a means of resolving an important methodological dispute among econometricians. We aim to show, through analysis of the main problem instrumental variables methods are used to resolve, (...) that the relationship of the principle to econometric methods is more nuanced than implied by previous work, but nevertheless may make a valuable contribution to the coherence and validity of existing methods.

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)

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 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.

Athenaeus of Attalia distinguishes two types of exercise or training (γυμνασία) that are required at each stage of life: training of the body and training of the soul. He says that training of the body includes activities like physical exercises, eating, drinking, bathing and sleep. Training of the soul, on the other hand, consists of thinking, education, and emotional regulation (in other words, 'philosophy'). The notion of 'training of the soul' and the contrast between 'bodily' and 'psychic' exercise is common (...) in the Academic and Stoic traditions Athenaeus is drawing from; however, he is the earliest extant medical author to distinguish these kinds of training and to treat them as equally important aspects of regimen. In this paper, I propose some reasons why he found this distinction useful, and I examine how he justified incorporating it into his writings on regimen, namely by attributing Plato's beliefs about regimen to Hippocrates, a strategy Galen would adopt well over a century later.

Several scholars have recently entertained proposals for "epistocracy," a political regime in which decision-making power is concentrated in the hands of a society's most informed and competent citizens. These proposals rest on the claim that we can expect better political outcomes if we exclude incompetent citizens from participating in political decisions because competent voters are more likely to vote "correctly" than incompetent voters. We develop what we call the objection from selection bias to epistocracy: a procedure that selects voters on (...) the basis of their observed competence---as epistocracy does---will often be "biased" in the sense that competent voters will be, on average, more likely than incompetent voters to possess certain attributes that reduce the probability of voting correctly. Our objection generalizes the "demographic objection" discussed in previous literature, showing that the range of realistic scenarios in which epistocracy is vulnerable to selection bias is substantially broader than previous discussions appreciate. Our discussion also shows that previous discussions have obscured the force of the threat of selection bias. Since we lack reasons to believe that epistocratic proposals can avoid selection bias, we have no reason to seriously entertain epistocracy as a practical proposal. (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.

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.

This paper is about the history of a question in ancient Greek philosophy and medicine: what holds the parts of a whole together? The idea that there is a single cause responsible for cohesion is usually associated with the Stoics. They refer to it as the synectic cause (αἴτιον συνεκτικόν), a term variously translated as ‘cohesive cause,’ ‘containing cause’ or ‘sustaining cause.’ The Stoics, however, are neither the first nor the only thinkers to raise this question or to propose a (...) single answer. Many earlier thinkers offer their own candidates for what actively binds parts together, with differing implications not only for why we are wholes rather than heaps, but also why our bodies inevitably become diseased and fall apart. This paper assembles, up to the time of the Stoics, one part of the history of such a cause: what is called ‘the synechon’ (τὸ συνέχον) – that which holds things together. Starting with our earliest evidence from Anaximenes (sixth century BCE), the paper looks at different candidates and especially the models and metaphors for thinking about causes of cohesion which were proposed by different philosophers and doctors including Empedocles, early Greek doctors, Diogenes of Apollonia, Plato and Aristotle. My goal is to explore why these candidates and models were proposed and how later philosophical objections to them led to changes in how causes of cohesion were understood. (shrink)

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.

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.

Republicans hold that people are dominated merely in virtue of others' having unconstrained abilities to frustrate their choices. They argue further that public officials may dominate citizens unless subject to popular control. Critics identify a dilemma. To maintain the possibility of popular control, republicans must attribute to the people an ability to control public officials merely in virtue of the possibility that they might coordinate their actions. But if the possibility of coordination suffices for attributing abilities to groups, then, even (...) in the best case, countless groups will be dominating because it will be possible for their members to coordinate their actions with the aim of frustrating others' choices. We argue the dilemma is apparent only. To make our argument, we present a novel interpretation of the republican concept of domination with the help of a game-theoretic model that clarifies the significance of collective action problems for republican theory.

The received view in the history of the philosophy of psychology is that the logical positivists—Carnap and Hempel in particular—endorsed the position commonly known as “logical” or “analytical” behaviourism, according to which the relations between psychological statements and the physical-behavioural statements intended to give their meaning are analytic and knowable a priori. This chapter argues that this is sheer legend: most, if not all, such relations were viewed by the logical positivists as synthetic and knowable only a posteriori. It then (...) traces the origins of the legend to the logical positivists’ idiosyncratic extensional or at best weakly intensional use of what are now considered crucially strongly intensional semantic notions, such as “translation,” “meaning” and their cognates, focussing on a particular instance of this latter phenomenon, arguing that a conflation of explicit definition and analyticity may be the chief source of the legend.

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)

This dissertation is a collection of essays exploring the role of metaphor in Aristotle’s scientific method. Aristotle often appeals to metaphors in his scientific practice; but in the Posterior Analytics, he suggests that their use is inimical to science. Why, then, does he use them in natural science? And what does his use of metaphor in science reveal about the nature of his scientific investigations? I approach these questions by investigating the epistemic status of metaphor in Aristotelian science. In the (...) first essay, I defend an interpretation of metaphor as a type of heuristic reasoning: I claim that Aristotle uses metaphor to express conditions an explanation in natural science must meet if it is to explain regular, ordered change. These conditions specify the kinds of causes—particularly unmoved efficient causes—which the inquirer into nature is seeking. In the second essay, I look to Aristotle’s use of certain endoxa or common beliefs as explanatory principles in science, and show that his use of these principles is similar to his use of metaphor. In the final essay, I present a historical study of the analogy of art and nature, and I suggest that by looking to how the Greeks understood the role of inquiry in the arts, we can shed some light on Aristotle’s views concerning the method of inquiry he thinks the natural scientist should adopt.

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)

Normative political theorists frequently compare hypothetical scenarios for the purpose of identifying reasons to prefer one kind of institution to alternatives. We examine three types of "unfair" comparisons and the reasoning errors associated with each. A theorist makes an _obscure comparison_ when one (or more) of the alternatives under consideration is underspecified; a theorist makes a _mismatched comparison_ when they fail to hold fixed the relevant contextual factors while comparing alternatives; and a theorist makes an _irrelevant comparison_ when they compare (...) alternatives assuming contextual factors that differ in important respects from those they "should" assume given their theoretical aims. We then introduce the notion of a modeling mindset and show how this mindset can help theorists detect and avoid the three types of error. We conclude with a reconstruction of Cohen's (2009) camping trip thought experiment to illustrate the approach. (shrink)

The paper presents a new theory of perceptual demonstrative thought, the property-dependent theory. It argues that the theory is superior to both the object-dependent theory (Evans, McDowell) and the object-independent theory (Burge).

In this paper I attempt to discover the object of Aristotle’s God’s νόησις in Metαphysics Λ.9. In Section I, I catalogue existing interpretations and mention the two key concepts of (i) God’s substancehood and (ii) his metaphysical simplicity. In Section II, I explore the first two aporiae of Λ.9 – namely (1) what God’s οὐσία is and (2) what God intelligizes. In Section III, I show how Aristotle solves these aporiae by contending that God’s οὐσία is actually intelligizing, and being (...) determined to do so by himself, and that the object of his νόησις is himself, such that he intelligizes his own οὐσία, and I explain what this means. In Section IV, I present the second pair of aporiae in Λ.9 and show how, by solving these, Aristotle clarifies the position arrived at in Section III. Lastly, in Section V, I present the final aporia and its solution, and conclude that Aristotle’s God is a radically-unified Narcissus-God who intelligizes his own οὐσία. (shrink)

When are inequalities in political power undemocratic, and why? While some writers condemn any inequalities in political power as a deviation from the ideal of democracy, this view is vulnerable to the simple objection that representative democracies concentrate political power in the hands of elected officials rather than distributing it equally among citizens, but they are no less democratic for it. Building on recent literature that interprets democracy as part of a broader vision of social equality, I argue that concentrations (...) of political power are incompatible with democracy, and with a commitment to social equality more generally, when they consist in some having greater arbitrary power to influence decisions according to their idiosyncratic preferences. A novel account of the relationship between power and social status clarifies the role of social equality in the justification of democracy, including a representative democracy in which public officials have more political power than ordinary citizens.

The existence of object-dependent thoughts has been doubted on the grounds that reference to such thoughts is unnecessary or 'redundant' in the psychological explanation of intentional action. This paper argues to the contrary that reference to object-dependent thoughts is necessary to the proper psychological explanation of intentional action upon objects. Section I sets out the argument for the alleged explanatory redundancy of object-dependent thoughts; an argument which turns on the coherence of an alternative 'dual-component' model of explanation. Section II rebuts (...) this argument by showing the dual-component model to be incoherent precisely because of its exclusion of object-dependent thoughts. Section III concludes with a conjecture about the further possible significance of object-dependent thoughts for the prediction of action. (shrink)

In democracies citizens are supposed to have some control over the general direction of policy. According to a pretheoretical interpretation of this idea, the people have control if elections and other democratic institutions compel officials to do what the people want, or what the majority want. This interpretation of popular control fits uncomfortably with insights from social choice theory; some commentators—Riker, most famously—have argued that these insights should make us abandon the idea of popular rule as traditionally understood. This article (...) presents a formal theory of popular control that responds to the challenge from social choice theory. It makes precise a sense in which majorities may be said to have control even if the majority preference relation has an empty core. And it presents a simple game-theoretic model to illustrate how majorities can exercise control in this specified sense, even when incumbents are engaged in purely re-distributive policymaking and the majority rule core is empty.
