I will contrast the two main approaches to the foundations of statistical mechanics: the individualist approach and the ensemblist approach. I will indicate the virtues of each, and argue that the conflict between them is perhaps not as great as often imagined.

In the last quarter of the nineteenth century, Ludwig Boltzmann explained how irreversible macroscopic laws, in particular the second law of thermodynamics, originate in the time-reversible laws of microscopic physics. Boltzmann’s analysis, the essence of which I shall review here, is basically correct. The most famous criticisms of Boltzmann’s later work on the subject have little merit. Most twentieth century innovations – such as the identification of the state of a physical system with a probability distribution on its phase space, (...) of its thermodynamic entropy with the Gibbs entropy of , and the invocation of the notions of ergodicity and mixing for the justification of the foundations of statistical mechanics – are thoroughly misguided.

Joseph Agassi develops a humanist world view in his last single-authored book through confronting the challenges facing the humanist world view. The three challenges that Agassi confronts are: 1. how do we rationally choose ways of life, including the life of rationality? 2. is humanity worthwhile? 3. how can we improve liberal democracy in our fractured societies where extremists seek to gain control?

The introduction of genetically engineered crops in agriculture in the mid-1990s has been heralded as the advent of the Second Green Revolution. Among the expectations were high yields, fewer inputs like pesticides, and new nutritionally enhanced foods. Around the same period that traditional breeding was eclipsed by molecular breeding, the concept of sustainability was introduced into the working lexicon of many disciplines, practitioners, and corporations. This chapter discusses the principles of sustainability and their applications to agriculture, evaluates specific GMOs against (...) the criteria for sustainable agriculture, and argues that GMO crops must be understood within an agro-ecological system.

Bohmian mechanics, which is also called the de Broglie-Bohm theory, the pilot-wave model, and the causal interpretation of quantum mechanics, is a version of quantum theory discovered by Louis de Broglie in 1927 and rediscovered by David Bohm in 1952. It is the simplest example of what is often called a hidden variables interpretation of quantum mechanics. In Bohmian mechanics a system of particles is described in part by its wave function, evolving, as usual, according to Schrödinger's equation. However, the (...) wave function provides only a partial description of the system. This description is completed by the specification of the actual positions of the particles. The latter evolve according to the.. (shrink)

Bohmian mechanics is arguably the most naively obvious embedding imaginable of Schr¨ odinger’s equation into a completely coherent physical theory. It describes a world in which particles move in a highly non-Newtonian sort of way, one which may at first appear to have little to do with the spectrum of predictions of quantum mechanics. It turns out, however, that as a consequence of the defining dynamical equations of Bohmian mechanics, when a system has wave function ψ its configuration is typically (...) random, with probability density ρ given by |ψ|2, the quantum equilibrium distribution. It also turns out that the entire quantum formalism, operators as observables and all the rest, naturally emerges in Bohmian mechanics from the analysis of “measurements.” This analysis reveals the status of operators as observables in the description of quantum phenomena, and facilitates a clear view of the range of applicability of the usual quantum mechanical formulas.

Conway and Kochen have presented a “free will theorem” [4, 6] which they claim shows that “if indeed we humans have free will, then [so do] elementary particles.” In a more precise fashion, they claim it shows that for certain quantum experiments in which the experimenters can choose between several options, no deterministic or stochastic model can account for the observed outcomes without violating a condition “MIN” motivated by relativistic symmetry. We point out that for stochastic models this conclusion is (...) not correct, while for deterministic models it is not new. In the way the free will theorem is formulated and proved, it only concerns deterministic models. But Conway and Kochen have argued [4, 5, 6, 7] that “randomness can’t help,” meaning that stochastic models are excluded as well if we insist on the conditions “SPIN”, “TWIN”, and “MIN”. We point out a mistake in their argument. Namely, the theorem is of the form deterministic model with SPIN & TWIN & MIN ⇒ contradiction , (1) and in order to derive the further claim, which is of the form stochastic model with SPIN & TWIN & MIN ⇒ contradiction , (2) Conway and Kochen propose a method for converting any stochastic model into a deterministic one [4].

This edited volume draws upon Lacanian psychoanalytic theory to examine the conscious and unconscious forces underlying race as a social formation, conceptualizing race, racial identity, and racism in ways that go beyond traditional modes of psychoanalytic thought Featuring contributions from Lacanian scholars from diverse geographical and disciplinary contexts, chapters span a wide breadth of topics including white nationalism and contemporary debates over confederate monuments; emergent theories of race rooted in Afropessimism and postcolonialism; Latinx and other racialized groups; apartheid and American (...) slavery; and applications of Lacan's concepts of the lamella, drive and sexuation to processes of racialization. The collection both reorients readers' understandings of race through its deployment of Lacanian theory and redefines the Lacanian subject through its theorizing of subjectivity in relation to race, racism and racial identification. Lacan and Race will be a definitive text for psychoanalytic theorists and contemporary scholars of race and appeal to readers across the fields of psychology, cultural studies, humanities, politics, and sociology.

There is no grander topic for us today, and Wolin's treatment is penetrating, thorough, and authoritative. This is a major work of political theory.

We consider an isolated, macroscopic quantum system. Let H be a microcanonical “energy shell,” i.e., a subspace of the system’s Hilbert space spanned by the (finitely) many energy eigenstates with energies between E and E + δE. The thermal equilibrium macro-state at energy E corresponds to a subspace Heq of H such that dim Heq/ dim H is close to 1. We say that a system with state vector ψ H is in thermal equilibrium if ψ is “close” to Heq. (...) We show that for “typical” Hamiltonians with given eigenvalues, all initial state vectors ψ0 evolve in such a way that ψt is in thermal equilibrium for most times t. This result is closely related to von Neumann’s quantum ergodic theorem of 1929. (shrink)

Lessons in the study of habits by Walter L. Sheldon. This book is a reproduction of the original book published in 1903 and may have some imperfections such as marks or hand-written notes.

This is a significantly expanded edition of one of the greatest works of modern political theory. Sheldon Wolin's Politics and Vision inspired and instructed two generations of political theorists after its appearance in 1960. This new edition retains intact the original ten chapters about political thinkers from Plato to Mill, and adds seven chapters about theorists from Marx and Nietzsche to Rawls and the postmodernists. The new chapters, which show how thinkers have grappled with the immense possibilities and dangers (...) of modern power, are themselves a major theoretical statement. They culminate in Wolin's remarkable argument that the United States has invented a new political form, "inverted totalitarianism," in which economic rather than political power is dangerously dominant. In this new edition, the book that helped to define political theory in the late twentieth century should energize, enlighten, and provoke generations of scholars to come. Wolin originally wrote Politics and Vision to challenge the idea that political analysis should consist simply of the neutral observation of objective reality. He argues that political thinkers must also rely on creative vision. Wolin shows that great theorists have been driven to shape politics to some vision of the Good that lies outside the existing political order. As he tells it, the history of theory is thus, in part, the story of changing assumptions about the Good. In the new chapters, Wolin displays all the energy and flair, the command of detail and of grand historical developments, that he brought to this story forty years ago. This is a work of immense talent and intense thought, an intellectual achievement that will endure. (shrink)

From the early years of the Common Era to 1700, Indian intellectuals explored with unparalleled subtlety the place of emotion in art. Their investigations led to the deconstruction of art's formal structures and broader inquiries into the pleasure of tragic tales. _Rasa_, or taste, was the word they chose to describe art's aesthetics, and their passionate effort to pin down these phenomena became its own remarkable act of creation. This book is the first in any language to follow the evolution (...) of rasa from its origins in dramaturgical thought--a concept for the stage--to its flourishing in literary thought--a concept for the page. _Reader on Rasa_ incorporates primary texts by every significant thinker of classical Indian aesthetics, many never translated before. The arrangement of the selections captures the intellectual dynamism that has powered this debate for centuries. Headnotes explain the meaning and significance of each text, a comprehensive introduction summarizes major threads in intellectual-historical terms, and critical endnotes and an extensive bibliography add further depth to the selections. The Sanskrit theory of emotion in art is one of the most sophisticated in the ancient world, a precursor of the work being done today by critics and philosophers of aesthetics. This volume's conceptual detail, historical precision, and clarity will appeal to any scholar interested in a full portrait of global intellectual development. __Reader on Rasa___ is the inaugural book in the Historical Sourcebooks in Classical Indian Thought series, edited by Sheldon Pollock. These text-based books guide readers through the most important forms of classical Indian thought, from epistemology, rhetoric, and hermeneutics to astral science, yoga, and medicine. Each volume provides fresh translations of key works, headnotes to contextualize selections, a comprehensive analysis of major lines of development within the discipline, and exegetical and text-critical endnotes, as well as a bibliography. Designed for comparativists and interested general readers, Historical Sourcebooks is also a great resource for advanced scholars seeking authoritative commentary on challenging works._. (shrink)

How do we alleviate the cultural obstacles to dialogue? The answer, we argue, is by using Socratic dialogue as the architecture for the design of social systems, societies can overcome the cultural obstacles to inter-cultural dialogue of imposed insider-outsider social divisions, of imposed social hierarchies, and of imposed social walls around cultures. We elaborate on how Socratic Dialogue removes those cultural obstacles to intercultural dialogue when used as social architecture or as a blueprint for institutions that open the social gates (...) to all “outsiders” through the social levelling of hierarchies, and through the creation of social bridges among all “parallel” cultures.

Previous works were described as too technical for the average person. In this text, Amos does an exceptional job of explaining the subject in terms that are easily understood by everyone with an interest in this area.

This paper surveys the various leading options as a metric for measuring the level of development in a society. It is then argued that the appropriate metric will be value-laden in a (fairly) rich sense. One metric is then shown to have substantial advantages in this regard.

In [3] John S. Bell proposed how to associate particle trajectories with a lattice quantum field theory, yielding what can be regarded as a |Ψ|2-distributed Markov process on the appropriate configuration space. A similar process can be defined in the continuum, for more or less any regularized quantum field theory; such processes we call Bell-type quantum field theories. We describe methods for explicitly constructing these processes. These concern, in addition to the definition of the Markov processes, the efficient calculation of (...) jump rates, how to obtain the process from the processes corresponding to the free and interaction Hamiltonian alone, and how to obtain the free process from the free Hamiltonian or, alternatively, from the one-particle process by a construction analogous to “second quantization.” As an example, we consider the process for a second quantized Dirac field in an external electromagnetic field.

The social science approach to risk has matured over the past two decades, with distinct paradigms developing in disciplines such as anthropology, economics, geography, psychology, and sociology. Social Theories of Risk traces the intellectual origins and histories of twelve of the established and emerging paradigms from the perspective of their principal proponents. Each contributor examines the underlying assumptions of his or her paradigm, the foundational issue it seeks to address, and likely future directions of research. Taken together, these essays illustrate (...) that the principal achievement of social sciences has been to broaden the debate about risk beyond the narrow, technical considerations of engineers and the physical and life sciences. The authors conclude that expert knowledge is not value-free, that public perceptions of and attitudes toward risks vary according to a wide range of social, psychological, and cultural variables, and that public opposition to particular risks cannot be assuaged by technical fixes. The essays reveal the circuitous paths that lead people to the study of risk, highlight how these paths have crossed and discuss some of the seminal influences on individuals and the field in general. Social Theories of Risk presents a broad, retrospective view of the state of the theory in the social sciences, written by many who have been on the cutting edge of risk research since its early days. The book includes both established and novel perspectives that address the theoretical foundations of the field and reflect what we know about risk as a psychological, social, and cultural phenomenon. The collection of papers not only informs us of the tributary ideas that spawned the social studies of risk, but also how the field has matured. The biographical flavor of the essays provides fascinating reading for established members of the field, and a valuable entree for newcomers. It is an ideal college text for courses in the history of science, environmental policy, and science, technology, and society, as well as the burgeoning array of more specialized courses in risk assessment and management.

In the mid-1980s, social scientists compared outcome measures of related drug studies, some funded by private companies and others by nonprofit organizations or government agencies. The concept of a “funding effect” was coined when it was discovered that study outcomes could be statistically correlated with funding sources, largely in drug safety and efficacy studies. Also identified in tobacco research and chemical toxicity studies, the “funding effect” is often attributed, implicitly or explicitly, to research bias. This article discusses the meaning of (...) scientific bias in research, examines the strongest evidence for the “funding effect,” and explores the question of whether the “funding effect” is an indicator of biased research that is driven by the financial interests of the for-profit sponsor. This article argues that the “funding effect” is merely a symptom of the factors that could be responsible for outcome disparities in product assessment. Social scientists should not suspend their skepticism and choose as a default hypothesis that bias is always or typically the cause. (shrink)

The most puzzling issue in the foundations of quantum mechanics is perhaps that of the status of the wave function of a system in a quantum universe. Is the wave function objective or subjective? Does it represent the physical state of the system or merely our information about the system? And if the former, does it provide a complete description of the system or only a partial description? We shall address these questions here mainly from a Bohmian perspective, and shall (...) argue that part of the difficulty in ascertaining the status of the wave function in quantum mechanics arises from the fact that there are two different sorts of wave functions involved. The most fundamental wave function is that of the universe. From it, together with the configuration of the universe, one can define the wave function of a subsystem. We argue that the fundamental wave function, the wave function of the universe, has a law-like character. (shrink)

Ninety-five freshmen each recruited three peers to play a "group bidding game," an N-person prisoner’s dilemma in which anyone could win movie tickets depending on their scores in the game. Prior to playing, all participants completed a measure of prosocial value orientation. Replicating and extending earlier findings (Sheldon and McGregor 2000), our results show that prosocial participants were at a disadvantage within groups. Despite this vulnerability, prosocial participants did no worse overall than asocial participants because a counteracting group-level advantage (...) arose for prosocials, who tended to be concentrated in groups. Implications of this assortative process for the egoism/altruism debate, and for hierarchical selection theory, are discussed. (shrink)

We derive for Bohmian mechanics topological factors for quantum systems with a multiply-connected configuration space Q. These include nonabelian factors corresponding to what we call holonomy-twisted representations of the fundamental group of Q. We employ wave functions on the universal covering space of Q. As a byproduct of our analysis, we obtain an explanation, within the framework of Bohmian mechanics, of the fact that the wave function of a system of identical particles is either symmetric or anti-symmetric.

We consider the possibility that all particles in the world are fundamentally identical, i.e., belong to the same species. Different masses, charges, spins, flavors, or colors then merely correspond to different quantum states of the same particle, just as spin-up and spin-down do. The implications of this viewpoint can be best appreciated within Bohmian mechanics, a precise formulation of quantum mechanics with particle trajectories. The implementation of this viewpoint in such a theory leads to trajectories different from those of the (...) usual formulation, and thus to a version of Bohmian mechanics that is inequivalent to, though arguably empirically indistinguishable from, the usual one. The mathematical core of this viewpoint is however rather independent of the detailed dynamical scheme Bohmian mechanics provides, and it amounts to the assertion that the configuration space for N particles, even N “distinguishable particles,” is the set of all N -point subsets of physical 3-space.

Der Kunsthistoriker Ernst Hans Josef Gombrich hat einen „wissenschaftlichen“ oder kognitiven Ansatz zur Erforschung der Geschichte und Psychologie der Künste entwickelt, der sehr maßgeblich von der Wissenschaftstheorie seines engen Freundes Karl Popper beeinflusst worden ist. Die geistige Nähe zwischen beiden wird in Gombrichs zentraler Arbeit zur Wiederentdeckung der Repräsentation in der Renaissance und zur Historiografie der Kunst deutlich. Ihre Differenzen verdienen allerdings ebenfalls Beachtung. Gombrichs Ansicht zufolge verändern sich Geschmack und Stil entsprechend der von ihm so genannten „Logik der Mode“. (...) Gombrich hat dargelegt, auf welch vielfältige Weise Veränderungen in der Kunst sich vollziehen. Während sich die Moden in der Kunst auf unvorhersehbare, launenhafte Weise wandeln, tauchen technische Veränderungen als Lösungen für technische Probleme auf und werden im Modus von Versuch und Irrtum ermittelt. Auf diese Weise stieß Gombrich auf eine Antinomie in der Kunsttheorie: Handwerkliche Fähigkeiten und Können wandeln sich durch rationalen Fortschritt, während sich Stile durch den irrationalen Mitläufereffekt verändern. In der Kunst ist der relativistische Pluralismus zur Mode geworden, und diese Mode hat seine Antinomie ignoriert – und zwar, sofern er richtig liegt, recht willkürlich. (shrink)

Textures of Time is a rich and challenging book that raises a host of important and hard questions about historical narrative, form, and style; the sociology of texts; and the core problem of ascertaining historical truth. Two that pertain to the book’s main claims are of special interest to nonspecialist readers: Is register or style—“texture”—necessarily and everywhere diagnostic of “history”? Does a new kind of “historical consciousness” emerge in south India beginning in the sixteenth century, indeed as a sign of (...) an Indian early modernity? Textures is not the first book to argue that historical discourse is constitutively marked by a peculiar style, but the claim is beset by difficulties that scholars since Barthes have detailed. Rather than textures of time—accounts of what really happened in history—what these works offer us may be only pretextures of time, textualized forms of a human experience that make claims about its degrees and types of truth through representations of various states of temporality. Instead of assessing, then, whether these works are history or something else like “myth,” we might ask whether they invite us to transcend this very dichotomy, to try, that is, to make sense of historical forms of consciousness rather than to identify forms of historical consciousness. As for modernity, nothing in south Indian historiography from 1500–1800 remotely compares to the conceptual revolution of Europe. But why should we expect the newness of the early modern world to have been experienced the same way everywhere? Modernity across Asia may have shown simultaneity without symmetry. Should this asymmetry turn out to reveal continuity and not rupture, however, no need to lament the fact. There is no shame in premodernity. (shrink)
