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.

A non-technical introduction to quantum mechanics, the Everett interpretation, and the emergence of spacetime.

This book provides an account of the nature of time, especially time's arrow and the role of entropy, at a semi-popular level. Special attention is given to statistical mechanics, the past hypothesis, and possible cosmological explanations thereof.

I discuss "Poetic Naturalism" -- there is only one world, the natural world, but there are many ways of talking about it -- both as a general concept, and how it accounts for our actual world. I talk about emergence, fundamental physics, entropy and complexity, the origins of life and consciousness, and moral constructivism.

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.

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)

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.

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.

To the best of our current understanding, quantum mechanics is part of the most fundamental picture of the universe. It is natural to ask how pure and minimal this fundamental quantum description can be. The simplest quantum ontology is that of the Everett or Many-Worlds interpretation, based on a vector in Hilbert space and a Hamiltonian. Typically one also relies on some classical structure, such as space and local configuration variables within it, which then gets promoted to an algebra of (...) preferred observables. We argue that even such an algebra is unnecessary, and the most basic description of the world is given by the spectrum of the Hamiltonian and the components of some particular vector in Hilbert space. Everything else—including space and fields propagating on it—is emergent from these minimal elements. (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)

Graduate-level textbook in general relativity.

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)

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)

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)

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.

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)

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)

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.

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.

I propose a version of quantum mechanics featuring a discrete and finite number of states that is plausibly a model of the real world. The model is based on standard unitary quantum theory of a closed system with a finite-dimensional Hilbert space. Given certain simple conditions on the spectrum of the Hamiltonian, Schrödinger evolution is periodic, and it is straightforward to replace continuous time with a discrete version, with the result that the system only visits a discrete and finite set (...) of state vectors. The biggest challenges to the viability of such a model come from cosmological considerations. The theory may have implications for questions of mathematical realism and finitism. (shrink)

Science and religion both make claims about the fundamental workings of the universe. Although these claims are not a priori incompatible (we could imaginebeing brought to religious belief through scientific investigation), I will argue that in practice they diverge. If we believe that the methods of science can be used to discriminate between fundamental pictures of reality, we are led to a strictly materialist conception of the universe. While the details of modern cosmology are not a necessary part of this (...) argument, they provide interesting clues as to how an ultimate picture may be constructed. (shrink)

In Morality & Mathematics, Justin Clarke-Doane argues that it is hard to imagine being "a realist about, for example, the standard model of particle physics, but not about mathematics." I try to explain how that seems very possible from the perspective of a physicist. What is real is the physical world; mathematics starts from descriptions of the natural world and extrapolates from there, but that extrapolation does not imply any independent reality. -/- Submitted to an Analysis Reviews symposium on Clarke-Doane's (...)

Could there be a more auspicious day than 14 July on which to honor a French scholar? Though the idyllic setting of the Saint Bonaventure campus is far from the bustling Place de la Bastille, the date could hardly be more fitting for the recipient of the 2016 Franciscan Institute Medal, given Jacques Dalarun's truly revolutionary contributions to Franciscan scholarship.Born in 1952, on All Saints' Day, Jacques Dalarun worked his way up through the highly competitive French educational hierarchy, reaching the (...) level of professeur certifié by 1974, agrégé d'histoire by 1975, doctor in medieval history by 1984, and habilité à diriger les recherches by 1994.

This article sketches an intellectual history of the distinction between Christian theology and Christian ethics. The twists and turns of that history have been obscured by a recent tendency to deny the distinction's usefulness, as part of a wider strategy for reasserting theology's relevance to modern social problems. By contrast, earlier theologians assumed the value of the theology/ethics divide, interpreting it through Aristotelian, neo-Kantian, and finally Marxist categories. The distinction fell into disrepute because theologians struggled to maintain the distinction consistently (...) and disagreed on the concerns implicated by it, variously using it to affirm the moral subject's agency, the divine/human difference, or the complexity of real people's circumstances. Nonetheless, the distinction has persisted as a useful shorthand for recognizing the limitations of Christian theology, qua a conceptual discourse, in fully apprehending its subject matter of the Christian life.

The ethical significance of role occupancy has long gone under-acknowledged as a topic within normative ethics. To be more accurate, while certain social roles (including legal, medical, business, military, gender, and family roles) have been recognized as ethically significant, their significance has mostly been addressed piecemeal. We currently lack a developed literature on the ethical significance of social roles as such—on what they are, on why they appear to have ethical force, on the structure of that force, and on the (...) significance of social roles for identity and wellbeing. The contributors to this volume have set out to fix this, building on the small body of work that does already exist and extending it into new and unexpected areas, bringing out the diversity of ethical questions that arise for social roles. The topic, it turns out, is important not only for the ethics of various individual social roles, but also for an integrated understanding of a suite of other live topics such as collective agency, impartiality, special relationships, wellbeing and self, and social justice. The hope for this volume is that it advances the ethics of social roles as an important subfield of ethics, deserving of attention in its own right but also offering a new angle on these other more established literatures.

The United States is currently the linchpin of global trade, technology, and finance, and a military colossus, extending across the world with a network of bases and alliances. This book anticipates the possible issues raised by a transition between American dominance and the rise of alternative powers. While a 'post-American' world need not be any different than that of today, the risk associated with such a change provides ample reason for attentive study. Divided into four parts, 50 international relations scholars (...) explore and discuss: Power Transitions: addressing issues including the rise of China; the passing of American primacy and the endurance of American leadership. War and Peace: addressing nuclear weapons; the risk of war; security privatization and global insecurity Global Governance: addressing competition, trade, the UN, sovereignty, humanitarian intervention, law and power. Energy and the Environment: addressing resource conflict, petrol, climate change and technology. This unique project offers a compilation of disparate arguments by scholars and policy practitioners, encompassing a plurality of disciplines and theoretical perspectives. By providing clarity and focus to this essential debate on the future of the world in the next several decades, Debating a Post-American World will be of interest to students and scholars of International Relations and global politics, American politics, US Foreign policy and International Security.

Hegel’s ‘Natural Law’ essay is widely discussed but its substance and the implications of its argument are misunderstood. Hegel’s essay is most often read via other philosophers. Interpretations of this kind are useful but only illuminate those parts of Hegel’s text that intersect with other philosophers’ concerns. This article takes a different approach by focusing on the entirety of the essay and exploring the implications of its two primary arguments: firstly, that there has been a breach between philosophy and natural (...) law; secondly, that without philosophy natural law is thrown back on its own resources, producing two schools of post-philosophical thought—empiricism and formalism—neither of which is adequate to serve as its foundation. I argue that in response to this inadequacy Hegel sublates empiricism and formalism to develop undistorted intuition as a way of thinking designed to effect the re-philosophization of natural law.

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.

Shaftesbury thought that dogmatism was an epistemic vice that violated the norms of good inquiry by inhibiting the proper exercise of reason. One way that Shaftesbury attempted to defend against dogmatic thought and culture was to recommend that society followed the norms of what he called “polite conversation.” This notion has received a fair amount of scholarship. However, it was not Shaftesbury's only recommendation. The earl accused his contemporaries of being “too lazy and effeminate, and withal a little too cowardly, (...) to dare doubt!” (C 2.108). In so doing, Shaftesbury endorsed doubt. But just what does Shaftesbury mean by this endorsement? What is doubt? Why should we doubt? Under what conditions should we doubt? This article takes seriously Shaftesbury's invocation to doubt and develops an account of doubt that fits systematically within Shaftesbury's social, ethical, epistemic project. Doubt, for Shaftesbury, is an attitude that inoculates against dogmatism much like polite conversation is an activity that inoculates against dogmatic exchange. This article argues that Shaftesbury endorses doubt because it (1) promotes genuine inquiry and (2) motivates polite conversation, which itself tends to produce epistemically good outcomes. (shrink)

The last decade has seen a dramatic increase in literature on decolonisation of knowledge. The impression often given in recent literature is of wholesale neglect of the concerns of the decolonisation literature in what might be called ‘Western thought’ of preceding decades. This paper argues that Feyerabend was a notable figure within Western epistemic communities who expressed positions analogous to those of proponents of decolonisation. The first section presents the most striking contributions from Feyerabend’s work that, I suggest, bear on (...) questions of decolonisation. Four specific issues are identified based on those: the curriculum and the role of universities; the inspirational role of student protests; the concept of ‘epistemicide’; and, indigenous knowledge systems. The second section suggests a range of limitations of, and weaknesses in, Feyerabend’s analysis: no substantive engagement with history or literature on decolonisation; implicitly accepting the Сclaimed inherent association of science, rationalism and various forms of modernity with Western countries and cultures; the (rhetorical) construction of an unnecessary binary choice between science and traditional knowledge systems; underplaying agency through a form of othering; creating an unnecessarily stark binary of Western science and non-Western indigenous knowledge; and, as a consequence of all these, providing no substantive analysis of how science might be integrated with other knowledge systems and cultures. The concluding section provides a brief summary and identifies areas for future work. (shrink)

Whether economics warrants public trust depends on the extent to which assertions by economists can be deemed credible. Three examples from microeconomics are examined to assess how the discipline performs in this regard. First, a purely theoretical argument with broad conceptual implications: a quasi-evolutionary argument for rational choice based on the notion of money pumps. Second, a modelling-related claim with significant social implications: economists’ objection to minimum wages based on a simple supply-demand model. Third, methodological choices with implications for all (...) empirical work in microeconomics: the recent proclamation of a ‘credibility revolution’ in applied microeconomics through the use of experimental and quasi-experimental methods. These are assessed against proposed criteria for credibility: epistemic validity, epistemic reliability, and epistemic reflexivity. On the basis of the performance of the discipline against these criteria on the examples considered, I conclude that public distrust of economics and economists can be well-founded. (shrink)

Levinas has little to say about Romeo and Juliet, unlike some other plays by Shakespeare, but it nevertheless reflects his philosophy. In keeping with his phenomenology of eros, the title characters form a relationship which does not extend to the third party, and instead retreat into what Levinas calls the “dual solitude” of lovers. Romeo and Juliet form a closed community which excludes the rest of the fictive world of Verona, its loyalties and its laws. They even withdraw from the (...) temporality of their fictive world, into the atemporality of art and idolatry, frozen in the statues which their grieving parents offer to raise in their memories and in the story of which they are protagonists.

The article reflects upon the observational practices and methods developed by the early exponents of ethology committed to naturalistic field study and explores how their approaches and techniques influenced a wider field of popular natural-history filmmaking and photography. In doing so, my focus is upon three aspects of ethological field studies: the socio-technical devices used by ethologists to bring birds closer to them, the distinctive observational and representational practices which they forged, and the analogies they used to codify behaviour. This (...) assemblage of elements included hides or screens from which to watch wild birds without disturbing them, optics to extend human vision, pens and paper to sketch and fix patterns of behaviour, watches to record timings, photography to capture action and freeze movement, and illustration and photographs to visualize behaviour. Carried through natural-history networks, the practices, methods and theories of ethologists like Huxley and Tinbergen influenced popular natural-history filmmaking and photography more broadly from the 1940s, driving a behavioural turn in these cultural practices. This popularization of the ‘ethological eye’ was further facilitated by the convergence of socio-technical devices, forms of observation and dramatization in the work of the early exponents of naturalistic field studies of birds and the popular filmmakers.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Archive Feelings: A Theory of Greek Tragedy by Mario TelòSean LambertTelò, Mario. Archive Feelings: A Theory of Greek Tragedy. Ohio State University Press, 2020. 344pp.In Archive Feelings: A Theory of Greek Tragedy, Mario Telò takes aim at one of the most canonical (if also one of the most contested) features of Greek tragedy: its potential to deliver catharsis (12).1 Through careful close readings of Greek tragedies informed by (...) psychoanalytic theory and deconstruction, Telò makes a persuasive case that tragedy is anti-cathartic. “The Freudian take on catharsis is complicated, or even undercut,” he writes in the introduction, “by its own anti-cathartic latencies… We can accordingly look at tragedy as a form of dramatic poetry that finds its affective raison d’être… in these anti-cathartic feelings” (34).Telò states that the intent of Archive Feelings is mainly to intervene in the age-old debate, asking: “why do human beings enjoy tragedy?” (14). He suggests that the pleasure of tragedy is, in fact, a masochistic one: a denial of release or pleasure (such as would come from catharsis) that an audience or reader enjoys in its specifically joyless jouissance. At stake is “feeling material,” a “fantasy” of “merging into the impersonal, anorganic, universal matter of elemental life” (44) evoked in tragedy’s death-driven withdrawal from action. With this concept in mind, Telò goes beyond even his own ambitions for his project. More than merely intervening in debates about the pleasures of tragedy, he argues powerfully for the continuing relevance of Greek tragedy for critical theory today, particularly in light of the so-called “affective” and “material” turns in the humanities. Archive Feelings is thus a useful book for classicists conducting interdisciplinary and/or trans-historical research, but even more so for any scholar working within the constellation of psychoanalysis, deconstruction, queer theory, affect theory or critical race theory. Telò makes a persuasive case for tragedy as a lodestar within this firmament–a vital tool for thinking through problems within and across disciplines.In striking contradistinction to previous theorists of Greek tragedy, including Aristotle and Nietzsche, Telò locates the engine of Greek tragedy in the death drive. In so doing, he reads in ancient narratives a number of experiences such as “acceleration, hoarding, vertiginous suspension, [End Page 113] breathless looping, affective bulimia or binge-eating, serial cutting, trying to enter or fold in upon oneself, auto-immune inflammation” (14), and finds in “the orgasm as an unfinished, non-teleological pleasure,” a desire to return to a state of “inert matter” (13).2 Noting that the original meaning of the Greek word archê is “origin,” Telò connects this impulse to once again become “inert” with the desire to create archives. Thus, Telò sees Greek tragedies as both a model for projects of archival reconstruction as well as archival projects themselves: they are “anxious and debilitating” attempts to “re-create the past as it was” (13).3Telò’s study is divided into three parts: Archival Time, Archival Space, and Archival Endings, which attempt to “structurally reproduce the psychological temporalities of the archive” (49). In each of his five chapters, Telò elaborates the diverse narrative masochisms of Greek tragedy, exploring the various stakes and species of tragic anti-catharsis. In Chapter 1, Telò reads the “archive fever” of Sophocles’ Oedipus at Colonus against the “archive fatigue” of Euripides’ Phoenissae, finding in both of these plays—near the end of the epoch of ancient tragedy—an impulse toward “textual hoarding” (76) that both undermines the possibility of catharsis and “exhausts” (106) the possibilities of the genre (107). In both the “synchronic gathering of disparate fragments of experience” into the body of Oedipus before his death and the aesthetics of boredom, fatigue, and inertia that suffuse the Phoenissae, Telò locates a desire to store up, rather than purge, emotions such as pity and fear, in a flouting of the normal formula for catharsis (73).In Chapter 2, Telò looks at the figures of Heracles and Medea in their original myths and tragic incarnations, seeing in both the compulsion to recircle around scenes of their respective “primordial traumas” (145). In Euripides’s Medea, this move manifests in repeated references... (shrink)
