Organic chemists have been able to develop a robust, theoretical understanding of the phenomena they study; however, the primary theoretical devices employed in this field are not mathematical equations or laws, as is the case in most other physical sciences. Instead it is the diagram, and in particular the structural formula, that carries the explanatory weight in the discipline. To understand how this is so, it is necessary to investigate both the nature of the diagrams employed in organic chemistry and (...) how these diagrams are used in the explanations of the discipline. I will begin this paper by describing and characterizing the roles of the most important sort of diagram used in organic chemistry. Next I will present a model of explanations in organic chemistry and describe how diagrams contribute to these explanations. This will be followed by two examples that will support my abstract account of the role of diagrams in the explanations of organic chemistry. (shrink)

The Relational Blockworld (RBW) interpretation of non-relativistic quantum mechanics (NRQM) is introduced. Accordingly, the spacetime of NRQM is a relational, non-separable blockworld whereby spatial distance is only defined between interacting trans-temporal objects. RBW is shown to provide a novel statistical interpretation of the wavefunction that deflates the measurement problem, as well as a geometric account of quantum entanglement and non-separability that satisfies locality per special relativity and is free of interpretative mystery. We present RBW’s acausal and adynamical resolution of the (...) so-called “quantum liar paradox,” an experimental set-up alleged to be problematic for a spacetime conception of reality, and conclude by speculating on RBW’s implications for quantum gravity.

The biosphere coevolves with the atmosphere, hydrosphere and lithosphere to maintain a habitable space on Earth. Over billions of years – and despite periodic setbacks – it has evolved increasing complexity, from its microbial beginnings to the complex interactions between animals, plants, fungi and unicellular microscopic life that sustain its present state. Recently, the biosphere has been profoundly changed by humans. In part, this includes increased rates of extinction that are reminiscent of past fundamental perturbations to life. But the change (...) is even more profound, resulting from a combination of marked translocations of species beyond their indigenous ranges, overt concentration of biomass in humans and their farm animals, reconfiguration of landscape habitats and over-utilisation of ocean life, excessive appropriation of energy from the biosphere (including its fossilised component), and increasing interconnectivity between technology and life.

Notions of the cosmos are deep-rooted in human consciousness. They are expressed in our earliest monumental constructions as explanations of the world around us and in the practices of many indigenous peoples. Here we examine the physical cosmos from the perspective of life on Earth. We note a central importance for the Earth in the vastness of space, as a planetary oasis for a highly complex and long-lived biosphere, one now being fundamentally altered by humans. We refer to other notions (...) of the cosmos that may enable us to navigate a better path for life in the Anthropocene. (shrink)

We propose an adynamical, background independent approach to quantum gravity and unification whereby the fundamental elements of Nature are graphical units of space, time and sources. The transition amplitude for these elements of “spacetimesource” is computed using a path integral with discrete Gaussian graphical action. The unit of action for a spacetimesource element is constructed from a difference matrix K and source vector J on the graph, as in lattice gauge theory. K is constructed from graphical relations so that it (...) contains a non-trivial null space, and J is then restricted to the column space of K which ensures it is distributed in a divergence-free fashion over the spacetime defined by the element. This rule for the relational construct of K and J is our proposed fundamental axiom of physics and results in a self-consistency relationship between sources, the spacetime metric, and the stress-energy-momentum content of the element, rather than a dynamical law for time-evolved entities. In its most general form, the set of fundamental elements employed by lattice gauge theory contains scalar fields on nodes and links, and vector fields on nodes. To complete the fundamental set, we propose the addition of scalar fields on plaquettes and vector fields on links. We use this approach via modified Regge calculus to correct proper distance in the Einstein-deSitter cosmology model yielding a fit of the Union2 Compilation supernova data that matches ɅCDM without having to invoke accelerating expansion or dark energy.

We discuss the cities of the future, and how they might co-habit with the biosphere in a more mutually beneficial way. Mutualistic cities would blend with their local ecology, co-existing with the immediately available resources of water, life, energy and materials, and enhancing the biosphere so that many species can thrive, including people. Such cities can make a significant contribution to stabilizing the Earth System by sustaining and nurturing life in tune with the evolving local ecology through cyclic economies and (...) values prioritizing mutually supportive communities over economic growth. The term “mutualism” comes from biology, referring to inter-species relationships that are beneficial. Mutualistic cities would benefit human and non-human inhabitants by recycling materials, clean air, and water, and providing habitats for many species. (shrink)

_The Legacy of Herbert Marcuse: A Critical Reader_ is a collection of brand new papers by seventeen Marcuse scholars, which provides a comprehensive reassessment of the relevance of Marcuse's critical theory at the beginning of the 21st century. Although best known for his reputation in critical theory, Herbert Marcuse's work has had impact on areas as diverse as politics, technology, aesthetics, psychoanalysis and ecology. This collection addresses the contemporary relevance of Marcuse's work in this broad variety of fields and from (...) an international perspective. In Part One, veteran scholars of Marcuse and the Frankfurt school examine the legacy of various specific areas of Marcuse's thought, including the quest for radical subjectivity, the maternal ethic and the negative dialectics of imagination. Part Two focuses on a very new trend in Marcuse scholarship: the link between Marcuse's ideas and environmental thought. The third part of this collection is dedicated to the work of younger Marcuse scholars, with the aim of documenting Marcuse's reception among the next generation of critical theorists. The final section of the book contains recollections on Marcuse's person rather than his critical theory, including an informative look back over his life by his son, Peter. (shrink)

This dissertation is structured as a debate between Wittgenstein and Habermas concerning the rational implications of linguistic practices. The topic of the debate is set by Habermas's claim that the pragmatic presuppositions of everyday speech acts commit speakers to resolve differences, including differences in their linguistic and reasoning practices, through a process of rational argumentation called discourse. By contrast, Wittgenstein sees linguistic and reasoning practices as the given parameters of all argumentation, such that they themselves are not open to rational (...) criticism. ;The approach taken is to reconstruct and evaluate each of these positions in detail. After an introduction to Wittgenstein's language-game model of linguistic practices, his remarks concerning rule-following are subjected to a careful analysis. Using Kripke's interpretation as a foil, the argument is made that Wittgenstein does not seek a standard for the correct application of a rule distinct from how one actually applies it, but instead shows that such standards can ultimately be no part of the practice of following a rule. Specifically, intersubjective agreement is not needed as a standard; contrary to what is usually thought, Wittgenstein shows that monological rule-following is possible. This finding is then applied to reasoning practices, with the provisional conclusion that a practice of reasoning as a whole is also not open to rational criticism, but is instead marked by acritical certainty. ;Next Habermas's model of communicative action is reconstructed to show how it implies that given linguistic and reasoning practices must be open to rational criticism. Two arguments supporting this model are then distinguished and examined: one based on the distinction between illocution and perlocution, the other based on a pragmatic theory of meaning. Both are found insufficient to substantiate Habermas's claims against Wittgenstein. The conclusion is therefore drawn that everyday linguistic practices do not commit speakers to critical discourses. ;Against both thinkers, however, I argue that linguistic practices themselves need not license their own critical evaluation for it to be rational. Hence, rational criticism of these practices may still be possible, even where it is not required. (shrink)

We propose a path integral over graphs approach to quantum gravity and unification that requires a modification and reinterpretation of both general relativity and quantum field theory via their graphical instantiations, Regge calculus and lattice gauge theory, respectively. As we outline below, the spacetime metric and the matter and gauge field gradients on the graph are co-determining, so there is no “background spacetime” connoting existence independent of matter-energy-momentum, and the graphical action can be characterized geometrically via graphical boundary operators.

According to Alberto Coffa in The Semantic Tradition from Kant to Carnap, Kant’s account of mathematical judgment is built on a ‘semantic swamp’. Kant’s primitive semantics led him to appeal to pure intuition in an attempt to explain mathematical necessity. The appeal to pure intuition was, on Coffa’s line, a blunder from which philosophy was forced to spend the next 150 years trying to recover. This dismal assessment of Kant’s contributions to the evolution of accounts of mathematical necessity is fundamentally (...) backward-looking. Coffa’s account of how semantic theories of the a priori evolved out of Kant’s doctrine of pure intuition rightly emphasizes those developments, both scientific and philosophical, that collectively served to undermine the plausibility of Kant’s account. What is missing from Coffa’s story, apart from any recognition of Kant’s semantic innovations, is an attempt to appreciate Kant’s philosophical context and the distinctive perspective from which Kant viewed issues in the philosophy of mathematics. When Kant’s perspective and context are brought out, he can not only be seen to have made a genuinely progressive contribution to the development of accounts of mathematical necessity, but also to be relevant to contemporary issues in the philosophy of mathematics in underappreciated ways.

In my dissertation, I argue that contemporary interpretive work on Kant's philosophy of geometry has failed to understand properly the diagrammatic aspects of Euclidean reasoning. Attention to these aspects is amply repaid, not only because it provides substantial insight into the role of intuition in Kant's philosophy of mathematics, but also because it brings out both the force and the limitations of Kant's philosophical account of geometry. ;Kant characterizes the predecessors with which he was engaged as agreeing that mathematical judgments (...) are analytic a priori. This is an inadequate account of geometrical judgments for Kant, because it cannot be reconciled with the evident success of the Euclidean practice in producing a priori knowledge of the nature of space. The ubiquitous presence of diagrams in Euclidean proofs suggests that, at least in Kant's time, any plausible account of the establishment of geometrical judgments must provide for the role of quasi-perceptual representations of individuals. Kant's claim that mathematical judgments are synthetic a priori reflects, in its positive aspect, his recognition of the importance of these 'intuitive' representations to Euclidean reasoning. Furthermore, Kant's doctrine that geometrical knowledge is established by the construction of concepts in intuition can be usefully understood as an attempt to accommodate the role of diagrams in the establishment of synthetic a priori geometrical judgments. ;Both Kant's rejection of the analytic a priori account of mathematics and his positive account of geometry depend on the plausibility of his appeals to Euclidean practice. Attention to the role of diagrams in Euclidean proof supports Kant's contention that intuitive representations are an essential component of Euclidean reasoning; however, the role of diagrams in both reductio proofs and in proofs by cases brings out tensions in Kant's positive account. The use of diagrams to represent impossible geometrical situations in reductio proofs indicates that Kant's notion of 'construction in intuition' can have a broader application than the construction of instances of geometrical concepts . Similarly, proofs by cases undermine Kant's attempts to explain the generality of judgments established through the consideration of individuals by appeal to the rules for the construction of those individuals. ;Contemporary interpretive debates about Kant's philosophy of geometry have centered on the philosophical role played by his appeal to intuition. This appeal cannot be primarily understood as an attempt to establish that the fundamental assumptions of Euclidean geometry are necessary truths about space. Nor can the role for intuition be regarded as merely licensing moves in geometrical proofs like an inference rule in modern logic. Instead, by understanding Kant's appeal to intuition as, at least in part, an attempt to accommodate the diagrammatic features of Euclidean reasoning, a much richer role for intuition is revealed. Intuition is required to play a logical role by expressing spatial relationships and establishing the existence of geometrical entities. In addition, it plays a quasi-perceptual role by supporting the truth of certain claims appealed to during the course of Euclidean proof. (shrink)

ObjectiveBulimia nervosa and binge eating disorder are eating disorders characterized by recurrent binge eating episodes. Overlap exists between ED diagnostic groups, with BE episodes presenting one clinical feature that occurs transdiagnostically. Neuroimaging of the responses of those with BN and BED to disorder-specific stimuli, such as food, is not extensively investigated. Furthermore, to our knowledge, there have been no previous published studies examining the neural response of individuals currently experiencing binge eating, to low energy foods. Our objective was to examine (...) the neural responses to both low energy and high energy food images in three emotive categories in BN and BED participants.MethodsNineteen females with BN or BED, comprising the binge eating group, and 19 age-matched healthy control ’s completed thorough clinical assessment prior to functional MRI. Neural response to low energy and high energy foods and non-food images was compared between groups using whole-brain exploratory analyses, from which six regions of interest were then selected: frontal, occipital, temporal, and parietal lobes; insula and cingulate.ResultsIn response to low energy food images, the BEG demonstrated differential neural responses to all three low energy foods categories compared to HCs. Correlational analyses found a significant association between frequency of binge episodes and diminished temporal lobe and greater occipital lobe response. In response to high energy food images, compared to HC’s, the BEG demonstrated significantly decreased neural activity in response to all high energy food images. The HC’s had significantly greater neural activity in the limbic system, occipital lobe, temporal lobe, frontal lobe, and limbic system in response to high energy food images.ConclusionResults in the low energy food condition indicate that binge frequency may be related to increased aberrant neural responding. Furthermore, differences were found between groups in all ROI’s except the insula. The neural response seen in the BEG to disgust food images may indicate disengagement with this particular stimuli. In the high energy food condition, results demonstrate that neural activity in BN and BED patients may decrease in response to high energy foods, suggesting disengagement with foods that may be more consistent with those consumed during a binge eating episode.

In this paper we argue that individuals in modern societies can share a general appreciation of the contingency of moral and political engagement without endangering these purposeful attachments. Depending upon the acceptance of various cognitive conventions, social practices and institutions cannot be sustained by appeals to advantage alone, but these conventions do not demand ontological commitment. Transparent fictions rather than ideological illusions can suffice to sustain valued forms of life. In contrast to Rorty's ironic society in which "only the intellectuals (...) would be ironists", we suggest the benign disillusionment can characterize the public generally. (shrink)

We articulate the problems posed by the quantum liar experiment (QLE) for backwards causation interpretations of quantum mechanics, time-symmetric accounts and other dynamically oriented local hidden variable theories. We show that such accounts cannot save locality in the case of QLE merely by giving up “lambda-independence.” In contrast, we show that QLE poses no problems for our acausal Relational Blockworld interpretation of quantum mechanics, which invokes instead adynamical global constraints to explain Einstein–Podolsky–Rosen (EPR) correlations and QLE. We make the case (...) that the acausal and adynamical perspective is more fundamental and that dynamical entities obeying dynamical laws are emergent features grounded therein. (shrink)

The Anthropocene concept arose within the Earth System science (ESS) community, albeit explicitly as a geological (stratigraphical) time term. Its current analysis by the stratigraphical community, as a potential formal addition to the Geological Time Scale, necessitates comparison of the methodologies and patterns of enquiry of these two communities. One means of comparison is to consider some of the most widely used results of the ESS, the ‘planetary boundaries’ concept of Rockström and colleagues, and the ‘Great Acceleration’ graphs of Steffen (...) and colleagues, in terms of their stratigraphical expression. This expression varies from virtually non-existent (stratospheric ozone depletion) to pronounced and many-faceted (primary energy use), while in some cases stratigraphical proxies may help constrain anthropogenic process (atmospheric aerosol loading). The Anthropocene concepts of the ESS and stratigraphy emerge as complementary, and effective stratigraphic definition should facilitate wider transdisciplinary communication. (shrink)

This collection of Habermas's recent essays on philosophical topics continues the analysis begun in The Philosophical Discourse of Modernity. In a short introductory essay, he outlines the sources of twentieth-century philosophizing, its major themes, and the range of current debates. The remainder of the essays can be seen as his contribution to these debates.Habermas's essay on George Herbert Mead is a focal point of the book. In it he sketches a postmetaphysical, intersubjective approach to questions of individuation and subjectivity. In (...) other essays, he develops his distinctive, communications-theoretic approach to questions of meaning and validity. The book as a whole expands on his earlier efforts to define a middle ground between nostalgic revivals of metaphysical conceptions of reason and radical deconstructions of reason. Jürgen Habermas is Professor of Philosophy at the University of Frankfurt.The Essays: The Horizon of Modernity is Shifting. Metaphysics after Kant. Themes in Postmetaphysical Thinking.

The Anthropocene Working Group of the Subcommission on Quaternary Stratigraphy, of the International Commission on Stratigraphy, has been active since 2009. Its primary role is to consider the Anthropocene as a potential formal addition to the Geological Time Scale. Unusual in composition because many members work in disciplines other than stratigraphic geology —the Anthropocene incorporates geological, historical, and instrumental records— it initially needed to establish whether the Anthropocene could be the basis of a valid chronostratigraphic unit. That task achieved, work (...) then focused on gathering evidence from 12 sections in different geological settings around the world, to establish which of these might be proposed as a Global boundary Stratotype Section and Point (GSSP, or ‘golden spike’) to define the Anthropocene formally. The Group aims to submit a formal proposal on this in 2023. (shrink)

Research has shown that adults can engage in cognitive offloading, whereby internal processes are offloaded onto the environment to help task performance. Here, we investigate an application of this approach with children, in particular children with poor working memory. Participants were required to remember and recall sequences of colors by placing colored blocks in the correct serial order. In one condition the blocks were arranged to facilitate cognitive offloading (i.e., grouped by color), whereas in the other condition they were arranged (...) randomly. Across two experiments (total N = 166) the ordered condition improved task performance for children with low working memory ability. In addition, participants in Experiment 2 rated the difficulty of the two arrangements and performed a further condition in which they were given an opportunity to freely arrange the blocks before completing the task. Despite performing better in the ordered condition, children with low working memory ability did not rate the ordered arrangement as easier, nor did they choose an ordered arrangement when given the opportunity to do so. This research shows that cognitive offloading can also be a useful process in populations other than typical adults, and the implications of this work for supporting children with poor working memory are discussed.

It is an ideal with a resonance beyond the world of Catholic higher education for all in the academy who still respond to the beckoning vision of the ultimate unity of all human knowing and who view it, indeed, as a necessary inspiration if we are to succeed in according to our intellectual activities the sort of seriousness and moral significance they properly deserve." —Francis Oakley, President Emeritus, Williams College "There (...) is a real need, indeed an absolute necessity, for a Catholic university that is true to its religious values. By so being, it makes other, non-Catholic institutions that much better." —E. Gordon Gee, Chancellor, Vanderbilt University "Dean Roche has done a rare thing.

Globalization generates new structures of human interdependence and vulnerability while also posing challenges for models of democracy rooted in territorially bounded states. The diverse phenomena of globalization have stimulated two relatively new branches of political theory: theoretical accounts of the possibilities of democracy beyond the state; and comparative political theory, which aims at bringing non-Western political thought into conversation with the Western traditions that remain dominant in the political theory academy. This article links these two theoretical responses to globalization by (...) showing how comparative political theory can contribute to the emergence of new global “publics” around the common fates that globalization forges across borders. Building on the pragmatist foundations of deliberative democratic theory, it makes a democratic case for comparative political theory as an architecture of translation that helps deliberative publics grow across boundaries of culture.

Alienation and Connection addresses social constructs that perpetuate alienation through suffering. The contributors discuss how alienation through suffering in a variety of contexts can be transformed into connection and reconnection: human relationship with the environment, economic and social systems that disconnect and reconnect, cultural constructs that divide or can heal, encountered difference that brings opportunity, and various manifestations of personal pain that can be survived and even overcome.

Written by the great medieval Jewish philosopher Maimonides, The Guide of the Perplexed attempts to explain the perplexities of biblical language--and apparent inconsistencies in the text--in the light of philosophy and scientific reason. Composed as a letter to a student, The Guide aims to harmonize Aristotelian principles with the Hebrew Bible and argues that God must be understood as both unified and incorporeal. Engaging both contemporary and ancient scholars, Maimonides fluidly moves from cosmology to the problem of evil to the (...) end goal of human happiness. His intellectual breadth and openness makes The Guide a lasting model of creative synthesis in biblical studies and philosophical theology. (shrink)

The first evaluation and critique of Hegel's theory of tragedy and comedy, this book also develops an original theory of both genres.

Here we can find out about irony and the meaning of life, the politics of the nuclear family, Marxism in Springfield, the elusiveness of happiness, popular parody as a form of tribute, and why we need animated TV shows. As if all that weren't enough, this book actually contains the worst philosophy essay ever.

Philosophical interest in ecology is relatively new. Standard texts in the philosophy of biology pay little or no attention to ecology (though Sterelny and Griffiths 1999 is an exception). This is in part because the science of ecology itself is relatively new, but whatever the reasons for the neglect in the past, the situation must change. A good philosophical understanding of ecology is important for a number of reasons. First, ecology is an important and fascinating branch of biology with distinctive (...) philosophical issues that arise from its study. Second, ecology is only one small step away from urgent political, ethical, and management decisions about how best to live in an apparently increasingly-fragile environment. Third, philosophy of ecology, properly conceived, can contribute directly to both our understanding of ecology and help with its advancement. Philosophy of ecology can thus be seen as part of the emerging discipline of “biohumanities”, where biology and humanities disciplines together advance our understanding and knowledge of biology (Stotz and Griffiths forthcoming). In this paper, we focus primarily on this third role of the philosophy of ecology and consider a number of places where philosophy can play an important role in ecology. In the process, we..

Contemporary U.S. policy makers often characterize the U.S. counterinsurgency experience in El Salvador as a successful model to be followed in other contexts. This article argues that these characterizations significantly overstate the positive lessons of El Salvador, and ignore important cautionary implications. During the first part of the conflict, neither the Armed Forces of El Salvador nor the U.S. followed the tenets of counterinsurgency doctrine. The FAES killed tens of thousands of non-combatants in 1979 and 1980, before the civil war (...) even began. This repression may have preempted an incipient popular insurrection, but it also locked in a determined social base that enabled the armed left to build a highly effective and sustained insurgency. In 1984, the U.S. had to save the FAES from likely defeat through a major increase in military aid, especially airpower. When the Farabundo Martí National Liberation Front switched to a classical guerrilla strategy, the FAES, despite considerable U.S. aid, seldom followed best practices in counterinsurgency. Democratization and redistributional reforms were partial and flawed in implementation. The war settled into a stalemate that would likely have continued indefinitely had it not been for the collapse of the socialist bloc and significant changes in the interests of Salvadoran elites that were largely incidental to U.S. policies.The most important cautionary lesson is that indiscriminate violence against civilians early in a conflict can create dynamics that are very difficult to overcome in subsequent stages.
