The affinities of antibodies (Abs) for their target antigens (Ags) gradually increase in vivo following an infection or vaccination, but reach saturation at values well below those realisable in vitro. This ‘affinity ceiling’ could in many cases restrict our ability to fight infections and compromise vaccines. What determines the affinity ceiling has been an unresolved question for decades. Here, we argue that it arises from the strength of the chain of protein complexes that is pulled by B cells during the (...) process of Ag acquisition. The affinity ceiling is determined by the strength of the weakest link in the chain. We identify the weakest link and show that the resulting affinity ceiling can explain the Ab affinities realized in vivo, providing a conceptual understanding of Ab affinity maturation. We explore plausible evolutionary underpinnings of the affinity ceiling, examine supporting evidence and alternative hypotheses and discuss implications for vaccination strategies. (shrink)

We show that numerous distinctive concepts of constructive mathematics arise automatically from an “antithesis” translation of affine logic into intuitionistic logic via a Chu/Dialectica construction. This includes apartness relations, complemented subsets, anti-subgroups and anti-ideals, strict and non-strict order pairs, cut-valued metrics, and apartness spaces. We also explain the constructive bifurcation of some classical concepts using the choice between multiplicative and additive affine connectives. Affine logic and the antithesis construction thus systematically “constructivize” classical definitions, handling the resulting bookkeeping (...) automatically. (shrink)

The history of the Nicaraguan Revolution has received considerable analytical attention. Typically, the successful overthrow of the Somoza regime in the late 1970s is associated with the Frente Sandinista de Liberación Nacional, a Marxist/socialist inspired vanguard group. While the role Christians played in the revolution is often acknowledged as a significant one, in part because many Sandinista cadres were Christian revolutionaries, little attention has been paid to the degree to which Sandinismo, as a unique perspective on socialism, shares elective affinities (...) with liberation theology, a prophetic expression of Christianity. This manuscript sets out to explore the relationship between liberation theology and Sandinismo-as-socialism. It starts by considering the perspective of Christian revolutionaries on this relationship. It then identifies the electives affinities between the aforementioned cultural frameworks, and it evaluates the Nicaraguan Revolution in light of these elective affinities. The latter evaluation includes exploring the connection between Saint Paul and what it means to be a Sandinista revolutionary. (shrink)

This book is about what makes law possible. A stranger to contemporary legal practice might think such a book unnecessary, but the eight authors of this book share the view that what makes law possible is under siege today. The authors also share the hope that by exploring how law is a humanistic practice that involves whole persons, the siege will be reversed. The pathbreaking work of University of Michigan Law professor Joseph Vining provides the authors' focus for their varied (...) analyses of how law works not through force but, instead, through affinity.Vining's four books and other writings, spanning four decades, reveal the hidden connections by which men and women freely create and sustain a world of meaning through the phenomena we associate with law. Drawing on legal philosophy, theology, musicology, and other humanistic disciplines, the authors join Vining in discovering how law is, as Vining has written, “evidence of view and belief far stronger than academic statement or introspection can provide.” Law as Vining and the other authors reveal it is evidence of our better selves, not of the totalizing and brutalizing selves humans are capable of becoming, sometimes even under cover of law.In addition to the three editors, the book's authors are Joseph Vining, Rev. John McCausland, Hon. John T. Noonan, Jr., Steven Smith, and James Boyd White.Lawyers and all who care about law, the human future, and what human freedom can do to connect person to person as valued will find much to ponder in the chapters of this book. By avoiding jargon and the cliché, the authors follow Vining's lead in illuminating the deep springs of law's vitality and authority. (shrink)

The majority of the contemporary literature on Schelling and Heidegger focuses on the direct connection between the two philosophers – Heidegger’s engagement with Schelling’s Freedom essay. This paper, however, explores an implicit link between them on the topic of creation by reading Schelling’s Ages of the World alongside Heidegger’s ‘The Origin of the Work of Art’. It brings God’s creation in Schelling together with artistic creation in Heidegger and argues that the two have similarities in their structures, sources, and aims: (...) both creations are dependent on a two-fold struggle, the sources are either the absolute (in Schelling) or being (in Heidegger), and the aims are to reveal the divine principle (in Schelling) or the truth of being (in Heidegger) in the world. In making these comparisons, I argue that, in spite of Heidegger’s esoteric neologisms, his account of artistic creation is not as radically new as he himself claims. It can be read and better comprehended in the light of a Schellingian metaphysics of creation and, more broadly, in the light of the history of philosophy in general. Eventually, Heidegger’s philosophy remains committed to the tradition of philosophical theology, despite his own attempt to move beyond this tradition. (shrink)

Einstein's general relativity theory describes very well the gravitational phenomena in themacroscopic world. In themicroscopic domain of elementary particles, however, it does not exhibit gauge invariance or approximate Bjorken type scaling, properties which are believed to be indispensible for arenormalizable field theory. We argue that thelocal extension of space-time symmetries, such as of Lorentz and scale invariance, provides the clue for improvement. Eventually, this leads to aGL(4, R)-gauge approach to gravity in which the metric and the affine connection acquire (...) the status ofindependent fields. The Yang-Mills type field equations, the Noether identities, and conformal models of gravity are discussed within this framework. After symmetry breaking, Einstein's GR surfaces as an effective “low-energy” theory. (shrink)

In my paper, I intend firmly to criticize Taubes' interpretation of Benjamin's Theology as a modern form of Gnosticism. In a positive way, I sustain rather the thesis that Benjamin's Messianism is in close connection with his conception of reason and, in particularly, with the paradoxical unity of Mysticism and Enlightenment, which, according to the famous definition of Adorno, distinguishes his thought. As a radically anti-magical and anti-mythical conception of the historical time, Benjamin's Messianism has to be considered as an (...) original synthesis between motifs of the mystical tradition of the Jewish Kabbalah and motifs belonging to the rationalist tradition of the Jewish philosophy. Moving from Cohen's standpoint of a continuity between Maimonides and Kant, I consider therefore the affinity between his messianic conception of history and that of Benjamin. Both, Benjamin and Cohen, share, together with the reference to the a priori of the idea of justice, the reference to the Kantian connection between rationality and hope. Hence originates the non-eschatological Messianism of both. Motives of difference between Cohen and Benjamin’s messianic idea are to be found, conversely, in their different way to consider the idea of "the infinite task" and of its infinite fulfillment in the context of the historical time. Unlike the fundamentally ethical interpretation that Cohen gives of this relationship, Benjamin understands it ontologically in a monadological sense. This explains the constitutive relationship that exists, in Benjamin's philosophy, between Origin, Fragment and Revelation. In the light of this connection, Benjamin's messianic understanding of the historical time exceeds the Scholemian alternative between a restorative and a utopian conception of Messianism. Consequently, the Krausian motto “Ursprung ist das Ziel” displays its truth in the idea of the messianic fragment or spark. (shrink)

Cells in multicellular organisms often do not intermingle freely with each other. Differential cell affinities can contribute to organizing cells into different tissues. Drosophila limbs and the vertebrate central nervous system are subdivided into compartments. Cells in adjacent compartments do not mix. Cell interactions mediated by Notch-family receptors have been implicated in the specification of these compartment boundaries. Two recent reports analyze the role of the Notch signaling pathway in the generation of an affinity boundary in the Drosophila wing.1,2 The (...) first report1 analyzes the connection between Notch and the actin cytoskeleton. The second report2 analyzes the differential requirements of Notch and the transcription factor Supressor of Hairless in generating the affinity boundary.

A notable early result of David Makinson establishes that every monotone modal logic can be extended to LI, LV, or LF, and every antitone logic can be extended to LN, LV, or LF, where LI, LN, LV, and LF are logics axiomatized, respectively, by the schemas □α↔α, □α↔¬α, □α↔⊤, and □α↔⊥. We investigate logics that are both monotone and antitone (hereafter amphitone). There are exactly three: LV, LF, and the minimum amphitone logic AM axiomatized by the schema □α→□β. These logics, (...) along with LI, LN, and a wider class of “extensional” logics, bear close affinities to classical propositional logic. Characterizing those affinities reveals differences among several accounts of equivalence between logics. Some results about amphitone logics do not carry over when logics are construed as consequence or generalized (“multiple-conclusion”) consequence relations on languages that may lack some or all of the nonmodal connectives. We close by discussing these divergences and conditions under which our results do carry over. (shrink)

Théophile De Donder, a Belgian mathematician born in Brussels, elaborated two important ideas that created a bridge between thermodynamics and chemical kinetics. He invented the concept of the degree of advancement of a reaction, and, in 1922, he provided a precise mathematical form to the already known chemical affinity by translating Clausius’s uncompensated heat into formal language. These concepts merge in an important inequality that was the starting point for the formalization of non-equilibrium thermodynamics. The present article aims to reconstruct (...) how De Donder elaborated his ideas and developed them by exploring his teaching activity and its connection with his scientific production. Furthermore, it emphasizes the role played by the discussions with his disciples who became his collaborators. The paper analyzes De Donder’s efforts in participating in the second Solvay Chemistry Council in 1925 to call the attention of chemists to his mathematical approach. We explain why his work did not receive much attention at the time, and how, despite this, his formalization of chemical affinity became the basis for the birth of the so-called Brussels school of thermodynamics.

The use of reproductive techniques and the eventual reproductive negligence from the provider of reproductive services gave rise to situations in which the intended parents are deprived of raising a child genetically connected to them. Courts have been dealing with cases of those for years, but have systemically denied claimants compensation, failing to recognise as damage the loss of genetic connection. In 2017, for the first time, the Singapore High Court provided compensation for that damage, labelled “loss of genetic affinity”. (...) This paper will argue that the damage in question is the loss of genetic connection and results from a violation of reproductive rights because a key element of reproductive rights is to have children with whom we keep a genetic bond and raise them. The paper will explain why the arguments classically argued against such compensation are unfounded and it will argue for a compensation covering both patrimonial and non-patrimonial damages.

An important factor in judging whether two retinal images arise from the same object viewed from different positions may be the presence of certain properties or cues that are 'qualitative invariants' with respect to the natural transformations, particularly affine transformations, associated with changes in viewpoint. To test whether observers use certain affine qualitative cues such as concavity, convexity, collinearity, and parallelism of the image elements, a 'same-different' discrimination experiment was carried out with planar patterns that were defined by (...) four points either connected by straight line segments (line patterns) or marked by dots (dot patterns). The first three points of each pattern were generated randomly; the fourth point fell on their diagonal bisector. According to the position of that point, the patterns were concave, triangular (three points being collinear), convex, or parallel sided. In a 'same' trial, an affine transformation was applied to one of two identical patterns; in a 'different' trial, the affine transformation was applied after the point lying on the diagonal bisector was perturbed a short, fixed distance along the bisector, inwards for one pattern and outwards for the other. Observers' ability to discriminate 'same' from 'different' pairs of patterns depended strongly on the position of the fourth, displaced, point: performance varied rapidly when the position of the displaced point was such that the patterns were nearly triangular or nearly parallel sided, consistent with observers using the hypothesised qualitative cues. The experimental data were fitted with a simple probabilistic model of discrimination performance that used a combination of these qualitative cues and a single quantitative cue. (shrink)

Recently, some philosophers of science (e.g., Gürol Irzik, Michael Friedman) have challenged the ‘received view’ on the relationship between Rudolf Carnap and Thomas Kuhn, suggesting that there is a close affinity (rather than opposition) between their philosophical views. In support of this argument, these authors cite Carnap and Kuhn’s similar views on incommensurability, theory-choice, and scientific revolutions. Against this revisionist view, I argue that the philosophical relationship between Carnap and Kuhn should be regarded as opposed rather than complementary. In particular, (...) I argue that a consideration of the fundamentally disparate nature of the broader philosophical projects of Carnap (logic of science) and Kuhn (providing a theory of scientific revolutions)renders the alleged similarities between their views superficial in comparison to their fundamental differences. In defense of the received view, I suggest that Carnap and Kuhn are model representatives of two contrasting styles of doing philosophy of science, viz., logical analysis and historical analysis respectively. This analysis clarifies the role played by Kuhn’s Structure of Scientific Revolutions in the demise of logical empiricism in the second half of the twentieth-century. (shrink)

My research into Virtual Reality technology and its central property of immersion has indicated that immersion in Virtual Reality (VR) electronic systems is a significant key to the understanding of contemporary culture as well as considerable aspects of previous culture as detected in the histories of philosophy and the visual arts. The fundamental change in aesthetic perception engendered by immersion, a perception which is connected to the ideal of total-immersion in virtual space, identifies certain shifts in ontology which are relevant (...) to a better understanding of the human being. This understanding was achieved through a broad inquiry into the histories of Virtual Reality, philosophy, and the visual arts and has lead to the formulation of an aesthetic theory of immersive consciousness indicative of immersive culture. The primary subject of this discourse is immersion then: an experience which will be identified within the dissertation as the indispensable characteristic of Virtual Reality. The understanding of immersion arrived at here will be used to fashion a synchronous theory of art particularly informed by encounters and concepts of immersion into virtuality. To sufficiently address this subject in a scholarly fashion, I have researched, found and accumulated aesthetic and philosophic examples of immersive tendencies, as found within the histories of art and philosophy, which subsequently contributed towards the articulation of what I have come to call immersive consciousness. As a result of formulating such an immersive consciousness, a good deal of the basis for the questioning of the Western ontological tradition has been found in the Western tradition itself when we look with new eyes and ask new uncertain questions. Moreover, this immersive consciousness will be used to propose some abstract questions encircling today's electronic-based culture. Through the structuring of the argument within the thesis - and overtly within the conclusion - I have articulated a non-teleological creative strategy which provides the basis for an unconstraining integration of noologies (ways of semblancing the thinking process). This strategy provides a means of exemplifying - and for honoring - various methods of thinking. This structuring strategy is consistent with the 'hacker ethic' as defined by Steven Levy, as a demand that access to computers - and anything which might teach us something about the way the world works - should be unlimited and total. To follow this strategy, this dissertation has set out to understand how topical conceptions of virtual immersion connect to pre-existing systems of thought as revealed in art as they have extended out of antecedent ontological self-understandings, historical human self-understandings which have evidenced themselves in the elaboration of technological objectives. To do this I have forged a certain rhizomatic paternity/maternity for Virtual Reality within this dissertation by joining choice immersive examples of simulacra technology into mental connections with the relevant examples culled from the histories of art, architecture, information-technology, sex, myth, space, consciousness and philosophy.

The aim of my contribution is to outline three points of overlap between Hegel’s Philosophy of Right and Durkheim’s sociology of morality in their respective views on social ethics: I will start by characterizing their shared conviction that the foundation of any form of morality cannot be found in some abstract principles but in actually existing, institutionalized normative rules that inform us about our role-obligations. In the second step I will show that Hegel and Durkheim also share the social-theoretical conviction (...) that we should differentiate modern societies into three different spheres all entailing different sorts of role-obligations; a part of this step will also specifically deal with the question of how both thinkers conceive of the problems raised by the modern, capitalist market economy. In the third part of my contribution I will consider the question of whether we find in Hegel’s Philosophy of Right a placeholder for what Durkheim refers to as a kind of cosmopolitan ethics, a standpoint beyond the role-obligations connected to membership in individual states. In my conclusion I will raise the question of the relevance of Hegel’s and Durkheim’s shared views on the basis for social ethics for contemporary discussions in political and social philosophy.

In the face of the most recent developments in digital and visual art, the Internet, the latest frontiers and currents, the new languages and technologies, Souriau’s schema does not work, but his reflections on the aesthetic notions of instauration and skeuopoetics do, and they pertain both to classical painting and to future perspectives. In fact, we note strong connections with research that the philosopher had had conducted on feelings, relations, forms, and processes, in terms of synaesthesia and structural correspondences. (...) On the basis of his thinking, we can still argue the importance of these concepts and these relations as they relate to physical and phenomenal existence, to materiality and transcendence: a conceptual and imaginative universal that is considered to be eternal. Art is seen as the producer of things capable of performing actions that are purely physical. He makes this claim because these actions expressly and intentionally create things whose existence is their sole purpose. (shrink)

In this review paper, we discuss how gravity and spin can be obtained as the realization of the local Conformal-Affine group of symmetry transformations. In particular, we show how gravitation is a gauge theory which can be obtained starting from some local invariance as the Poincaré local symmetry. We review previous results where the inhomogeneous connection coefficients, transforming under the Lorentz group, give rise to gravitational gauge potentials which can be used to define covariant derivatives accommodating minimal couplings of (...) matter, gauge fields (and then spin connections). After we show, in a self-contained approach, how the tetrads and the Lorentz group can be used to induce the spacetime metric and then the Invariance Induced Gravity can be directly obtained both in holonomic and anholonomic pictures. Besides, we show how tensor valued connection forms act as auxiliary dynamical fields associated with the dilation, special conformal and deformation (shear) degrees of freedom, inherent to the bundle manifold. As a result, this allows to determine the bundle curvature of the theory and then to construct boundary topological invariants which give rise to a prototype (source free) gravitational Lagrangian. Finally, the Bianchi identities, the covariant field equations and the gauge currents are obtained determining completely the dynamics. (shrink)

Departing from the fact that László Moholy-Nagy’s Von Material zu Architektur (1929), had been an important source of inspiration for Alvar Aalto, this article examines the affinities between László Moholy-Nagy and Alvar Aalto’s intellectual positions. The article places emphasis on two particular ideas: how Aalto and Moholy-Nagy conceived the connection of biology with standardization and technology and its relationship to light and perception. Special attention is paid to the notions of “flexible standardisation” and rationalisation in Aalto’s thought, as well as (...) to his belief that nature and standardization should be conceived are closely interconnected. In regard to their shared intellectual development, the article sheds light on the first encounters of the two men including: their meeting at the second Congrès International de l’Architecture Moderne (CIAM) in 1929; the June 1931 Finish meeting of Aino Marsio-Aalto, Alvar Aalto, Moholy-Nagy and Ellen Frank; the June 1931 exchanges between Aalto and Moholy-Nagy during the inner circle CIAM meeting in Berlin; and the common stay of the Aaltos and Moholy-Nagy in London in 1933 are discussed. Particular emphasis is placed on Aalto’s “The Reconstruction of Europe is the Key Problem for the Architecture of Our Time”, in which he argued that standardization in architecture should draw upon biological models.

Recent research into LGBTQ kinship has suggested that reproductive technology might stabilise and/or disrupt dominant ideals about the importance of biogenetic relatedness in family formation. This article examines the way adults raised in lesbian, gay, bisexual, trans and queer (LGBTQ) households are interested in tracing queer family histories, rather than solely their biological relations. Data comes from biographical narrative interviews with twenty-two adult children raised by LGBTQ parents. The article examines how participants’ kinship stories relate to parents’ identities and journeys (...) to, and through, LGBTQ parenthood. Knowledge of queer kinship was pivotal in the process of self-making and enabled participants to produce and express connections between themselves and their LGBTQ parents. Furthermore, queer social histories allowed them to articulate their affinity to LGBTQ communities and culture more widely, particularly noting their knowledge and experience of socio-legal discrimination against LGBTQ people. Thus, kinship narratives of people raised by LGBTQ parents highlight that the desire to ‘know where we come from’ is not rooted exclusively in biogenetics. In this case, kinship stories disrupted the established biogenetic narrative, stressing the importance of LGBTQ culture and history for constructing a connection between collective and individual identity.

DNA–protein interactions are fundamental to many biological processes, including the regulation of gene expression. Determining the binding affinities of transcription factors (TFs) to different DNA sequences allows the quantitative modeling of transcriptional regulatory networks and has been a significant technical challenge in molecular biology for many years. A recent paper by Maerkl and Quake1 demonstrated the use of microfluidic technology for the analysis of DNA–protein interactions. An array of short DNA sequences was spotted onto a glass slide, which was then (...) covered with a microfluidic device allowing each spot to be within a chamber into which the flow of materials was controlled by valves. By trapping the DNA–protein complexes on the surface and measuring their concentrations microscopically, they could determine the binding affinity to a large number of DNA sequences that were varied systematically. They studied four TFs from the basic helix–loop–helix family of proteins, all of which bind to E‐box sites with the consensus CAnnTG (where “n” can be any base), and showed that variations in affinity for different sites allows each TF to regulate different genes.

From Einstein's point of view, his General Relativity Theory had strengths as well as failings. For him, its shortcoming mainly was that it did not unify gravitation and electromagnetism and did not provide solutions to field equations which can be interpreted as particle models with discrete mass and charge spectra, As a consequence, General Relativity did not solve the quantum problem, either. Einstein tried to get rid of the shortcomings without losing the achievements of General Relativity Theory. Stimulated by papers (...) of Weyl 465) and Eddington 194), from 1923 onward, he believed that, to reach this goal, one has to transit to space–times which possess more comprehensive geometrical structures than the Riemann space–time. This was the beginning of a decade's lasting search for a unitary field theory. We describe this exciting part of the history of physics, discuss achievements and failures of this development, and ask how these early attempts of a unified theory strike us today. Taking into account the fact that the Equivalence Principle only speaks for a geometrization of gravitation, we consider an alternative way to give those non-Riemannian structures which were introduced by the unitary field approach a physical meaning, namely the meaning of a generalized gravitational field. This is interesting since there are arguments in favor of such a generalization of General Relativity Theory, e.g., the problems the latter theory meets with if one tries to quantize it and to unify gravitation with other interactions.

A direct method showing the Thomas precession for an evolution of any vector quantity (a spatial part of a four-vector) is proposed. A useful application of this method is a possibility to trace correctly the presence of the Thomas precession in the Bargmann-Michel-Telegdi equation. It is pointed out that the Thomas precession is not incorporated in the kinematical term of the Bargmann-Michel-Telegdi equation, as it is commonly believed. When the Bargmann-Michel-Telegdi equation is interpreted in curved spacetimes, this term is shown (...) to be equivalent to the affine connection term in the covariant derivative of the spin four-vector evolving in a gravitational field. It then contributes to the geodetic precession. The described problem is an interesting and unexpected example showing that approximate methods used in special relativity, in this case to identify the Thomas precession, can distort the true meaning of physical laws.

The generally covariant Lagrangian densityG = ℛ + 2K ℒmatter of the Hamiltonian principle in general relativity, formulated by Einstein and Hilbert, can be interpreted as a functional of the potentialsg ikand φ of the gravitational and matter fields. In this general relativistic interpretation, the Riemann-Christoffel form Γ kl i = kl i for the coefficients г kl i of the affine connections is postulated a priori. Alternatively, we can interpret the LagrangianG as a functional of φ, gik, (...) and the coefficients г kl i . Then the г kl i are determined by the Palatini equations. From these equations and from the symmetry г kl i = г lk i for all matter fields with δℒ/δΓ=0 the Christoffel symbols again result. However, for Dirac's bispinor fields, δℒ/δΓ becomes dependent on the Dirac current, essentially with a coupling factor ∼Khc. In this case, the Palatini equations define a new transport rule for the spinor fields, according to which a second universal interaction results for the Dirac spinors, besides Einstein's gravitation. The generally covariant Dirac wave equations become the general relativistic nonlinear Heisenberg wave equations, and the second universal interaction is given by a Fermi-like interaction term of the V-A type. The geometrically induced Fermi constant is, however, very small and of the order 10−81erg cm3. (shrink)

A new theory of spacetime is proposed in which translations are considered as a part of the de Sitter gauge group. The theory is built along the general principles of classical gauge field theories, which are outlined. Applications of gauge principles to linear and affine connections are also given in order to make the presentation self-sufficient. A de Sitter invariant Lagrangian is constructed, which yields approximately Einstein's vacuum equations when it is subjected to variation with respect to gauge (...) potentials and the result expressed in a specific gauge class. As a difference from the usual use of de Sitter groups, the radius of its translations must be small in the present approach, which probably has the meaning of an elementary subatomic length. The solution of the equations describing flat spacetime is not the trivial zero-curvature connection of the conventional approach. (shrink)

The quest for a ‘unified field theory’, which aims to integrate gravitational and electromagnetic fields into a single field structure, spanned most of Einstein’s professional life from 1919 until his death in 1955. It is seldom noted that Hans Reichenbach was possibly the only philosopher who could navigate the technical intricacies of the various unification attempts. By analyzing published writings and private correspondences, this paper aims to provide an overview of the Einstein-Reichenbach relationship from the point of view of their (...) evolving attitudes toward the program of unifying electricity and gravitation. The paper concludes that the Einstein-Reichenbach relationship is more complex than usually portrayed. Reichenbach was not only the indefatigable ‘defender’ of relativity theory but also the caustic ‘attacker’ of Einstein’s and others’ attempts at unified field theory. Over the years, Reichenbach managed to provide the first, and possibly only, overall philosophical reflection on the unified field theory program. Thereby, Reichenbach was responsible for bringing to the debate, often for the first time, some of the central issues of the philosophy of space-time physics: (a) the relation between a theory’s abstract geometrical structures (metric, affine connection) and the behavior of physical probes (rods and clocks, free particles, and so on); (b) the question of whether such association should be regarded as a geometrization of physics or a physicalization of geometry; (c) the interplay between geometrization and unification in the context of a field theory.

I consider theories of gravity built not just from the metric and affine connection, but also other symmetric tensor. The Lagrangian densities are scalars built from them, and the volume forms are related to Cayley’s hyperdeterminants. The resulting diff-invariant actions give rise to geometric theories that go beyond the metric paradigm, and contain Einstein gravity as a special case. Examples contain theories with generalizeations of Riemannian geometry. The 0-tensor case is related to dilaton gravity. These theories can give rise (...) to new types of spontaneous Lorentz breaking and might be relevant for “dark” sector cosmology. (shrink)

The central thesis of my article is that people live a life worthy of a human being only as self-ruling members of some autarchic (or self-governing) communities. On the one hand, nobody is born as a self-ruling individual, and on the other hand, everybody can become such a person by observing progressively the non-aggression principle and, ipso facto, by behaving as a moral being. A self-ruling person has no interest in controlling her neighbors, but in mastering his own impulses, needs, (...) wishes, desires, behaviors, etc. Inasmuch as he is an imperfect being who lives in an imperfect world, he needs to share certain interests, beliefs, values, customs and other characteristics with other people, i.e. to be involved in some communities. Depending on the following four criteria – the regulatory principle, the essential resources, the specific feedback and the fundamental values –, the countless and manifold human communities can be grouped in three categories: (1) affinity communities, (2) economic communities, and (3) civic communities. In other words, every community or human behavior has an affinity, an economic, and a civic dimension. If a civic community is merely a state shaped society, it can be called a political community. All communities are intrinsically variable. Throughout time, they ceaselessly change their composition, values, interpersonal processes and relations, territory, etc. Interestingly enough, the variability is unanimously recognized and accepted in affinity and communities economic, but is denied or abusively interpreted in the case of state shaped societies. If we confuse two types of order − cosmos and taxis – and two types of rule – nomos and thesis –, as well as we exaggerate the importance of certain type of community we bring some social maladies, namely the traditionalism, the commercialism and the civism, (with the worst form of it – the politicality). Whatever the communities they are involved in, all persons relate (implicitly or explicitly) to the libertarian non-aggression principle, living their life in strict accordance with the logical implications of the position they adopt. People who respect the non-aggression axiom necessarily manifest self-control, consideration for the life and property of the others, commitment to offer value for value, love of freedom and a high level of individual responsibility. By contrast, people who violate this axiom – the villains and the statists – invariably strive to control their neighbors, behave as parasites or predators, prefer forced exchanges, reject the personal responsibility (at most accepting the idea of social responsibility), and apply double moral standards. The first category of people generates a libertarian civic discourse as a spontaneous order, and the second creates a political/ statist civic discourse as a result of the human design and will to power. As a spontaneous order, the libertarian civic discourse implies free involvement, peaceful coordination, free expression, free reproduction of ideas and the power of one. Every communication performance in the frame of the libertarian civic discourse is important and has relevant results. All participants to the libertarian civic discourse are automatically members of some self-governing communities (at least members of the general libertarian community). The most important thing for these communities is to be connected to a communicational infrastructure which would make possible free involvement, free expression and the free reproduction of ideas. Inasmuch as today democracy means the tyranny of majority and participatory democracy the tyranny of majority plus the power of vested (and illegitimate) interests, only the emergence of self-governing communities by libertarian discourse offers us a little hope. It’s high time to fall in love (again) with liberty and to embrace the non-aggression principle. We don’t have to create a perfect world, but we can strive to develop our human nature. (shrink)

Investigating connections between philosophical hermeneutics and neighbouring traditions of thought, this volume considers the question of how post-Heideggerian hermeneutics, as represented by Gadamer, Ricoeur and recent scholars following in their wake, relate to these traditions, both in general terms and bearing upon specific questions. The traditions covered in this volume-existentialism, pragmatism, poststructuralism, Eastern philosophy, and hermeneutics itself-are all characterized by significant internal diversity, adding to the difficulty in reaching an interpretation that is at once comparative and critical. None of (...) these traditions represent a unified system of belief; all are umbrella terms which are at once useful and imprecise, and the differences internal to each must not to be understated. An innovative work of comparative philosophy, this volume avoids oversimplification and offers specific analyses that treat hermeneutics in relation to particular themes and key figures in each of these traditions of thought. Philosophical hermeneutics is explicitly dialogical, and it is in this spirit that the authors of this book approach their subjects, revealing the important affinities and opportunities for mutually enriching conversations which have until now been overlooked.

A connection viewed from the perspective of integration has the Bianchi identities as constraints. It is shown that the removal of these constraints admits a natural solution on manifolds endowed with a metric and teleparallelism. In the process, the equations of structure and the Bianchi identities take standard forms of field equations and conservation laws.The Levi-Civita (part of the) connection ends up as the potential for the gravity sector, where the source is geometric and tensorial and contains an explicit gravitational (...) contribution.Nonlinear field equations for the torsion result. In a “low-energy” approximation (linearity andlow energy-momentumtransfer), the postulate that only charge and velocities contribute to the source transforms these equations into the Maxwell system. Moreover, the affine geodesics become the equations of motion of special relativity with Lorentz force in the same approximation [J. G. Vargas,Found. Phys. 21, 379 (1991)]. The field equations for the torsion must then be viewed as applying to an electromagnetic/strong interaction.A classical unified theory thus arises where the underlying geometry confers their contrasting characters to Maxwell-Lorentz electrodynamics and to an Einstein's-like theory of gravity. The highly compact field equations must, however, be developed in phase-spacetime, since the connection is velocity-dependent, i.e., Finsler-like.Further opportunities for similarities with present-day physics are discussed: (a) teleparallelism allows for the formulation of the torsion sector of the theory as a flat space theory with concomitant point-dependent transformations; (b) spinors should replace Lorentz frames in their role as the subjects to which the connection refers; (c) the Dirac equation consistent with the frame bundle for a velocity-dependent metric with Lorentz signature generates a weak-like interaction in the torsion sector.

In this paper, Leonard Waks investigates connections between listening and expertise or mastery, contrasting approaches from Eastern and Western philosophy. The first section accounts for listening in the Daoist classic Zhuangzi, a work addressing themes in Chinese philosophy through metaphor and story narratives. In one story a character named “Confucius” advises a student to fast the mind and listen recklessly. The affinity between reckless and what has been called “apophatic” listening is demonstrated by the shared feature of mental emptiness (...) — listening without the imposition of conceptual categories. The second section demonstrates close affinities between the account of listening and expertise or mastery in the Zhuangzi and in the account of expert perception in contemporary Western philosophy and psychology, as exemplified by phenomenologist Hubert Dreyfus.

This dissertation is a study of Thomas Aquinas’s and Godfrey of Fontaines’s moral philosophies. In this study, I conduct a detailed analysis of two Aristotelian commitments concerning the character virtues, namely, The Plurality of the Character Virtues and The Connection of the Character Virtues. Both Aquinas and Godfrey think that there are many distinct character virtues, however, one cannot possess these character virtues in separation from each other. In Chapter I, it is established that Aquinas believes in the plurality of (...) the character virtues not because of a specific account of the human soul, but because he is committed to a plurality in what he calls “the notion of goodness.” In Chapter II, it is argued that Aquinas’s account of virtuous action requires that there be a likeness between a person and their actions in terms of the notion of goodness explored in Chapter I. Chapters III through V lay out my account of how to reconstruct both Aquinas’s and Godfrey’s arguments for The Connection of the Character Virtues. The focus here lies on finding an interpretation that provides a valid argument for the connection of the character virtues. I argue that we ought to focus on a dependence between prudence and the character virtues. A central problem for this analysis is how to account for prudence as a unified virtue. On this issue, Godfrey provides an explicit argument that conceives of prudence as unified because prudence strikes a balance between the character virtues. Chapter VI investigates whether different groups, such as men and women, possess different types of character virtues. Godfrey offers a novel argument for the impossibility of male- and female-specific virtues. Finally, Chapter VII explores the question of how we should understand Godfrey’s account of prudence itself. I show that his discussion emphasizes the variable nature of ethics and that he endorses a view that has certain affinities with ethical particularism. (shrink)

This book provides the first in-depth exploration of the importance of music for Ludwig Wittgenstein’s life and work. Wittgenstein’s remarks on music are essential for understanding his philosophy: they are on the nature of musical understanding, the relation of music to language, the concepts of representation and expression, on melody, irony and aspect-perception, and, on the great composers belonging to the Austrian-German tradition. Biography and philosophy, this work suggests that Wittgenstein was a composer of philosophy who used the musical form (...) as a blueprint for his own writing and thought. For Wittgenstein music is not alone, but connects and resonates with our cultural forms of life. His relation to composers, especially to Richard Wagner and Gustav Mahler, enables Wittgenstein to address the question of how to do philosophy and compose music in the breakdown of tradition. Unlike his conservative musical sensibility, Wittgenstein’s philosophy is open to musical experiments. Reflecting on his remarks on music makes it possible to compare the therapeutic aim of his philosophical activity with that of music, and thus notice affinities between Wittgenstein and John Cage. Béla Szabados has a Ph.D. in philosophy from the University of Calgary and is professor of philosophy at the University of Regina. His publications include Wittgenstein Reads Weininger (2004), Wittgenstein at the Movies (2011) and Wittgenstein on Race, Gender, and Cultural Identity: Philosophy as a Personal Endeavour (2010).

In this paper I examine the relation between modern transhumanism and Nietzsche’s philosophy of the superhuman. Following Loeb, I argue that transhumanists cannot claim affinity to Nietzsche’s philosophy until they incorporate the doctrine of eternal recurrence to their project of technological enhancement. This doctrine liberates us from resentment against time by teaching us reconciliation with time and something higher than all reconciliation. Unlike Loeb, however, I claim that this “something higher” is not a new skill (prospective memory), but rather a (...) love for the past in the form of loving that aspect of it that is still with us, namely, the will to power itself, which is the engine of all life. Love of the past is thus equivalent to love of life. Since human beings are conscious incarnations of the will to power, in our case, love of life manifests itself as love of our humanity or love for that aspect of ourselves that connects us to each other, for we recognize it to be the same in all of us. Thus, learning this kind of love enables us to joyfully coordinate our wills in the pursuit of Zarathustra’s superhuman ideal without turning it into a destructive mockery of itself. While learning this kind of love would facilitate a joyful version of transhumanism, I conclude by suggesting that it is unlikely to be achieved through technological interventions of the sort envisioned by transhumanists. Instead, it requires the kind of participatory pedagogical program that Nietzsche thought his Zarathustra would fulfill. (shrink)

The Oxford Handbook of Comparative Political Theory provides an entry point into this burgeoning field by both synthesizing and challenging the terms that motivate it. The handbook demonstrates how mainstream political theory can and must be enriched through attention to genuinely global, rather than parochially Euro-American, contributions to political thinking. Entries emphasize exploration of substantive questions about political life-ranging from domination to political economy to the politics of knowledge-in a range of global contexts, with attention to whether and how those (...) questions may be shared, contested, or reformulated across differences of time, space, and experience. They connect comparative political theory to cognate disciplines including postcolonial theory, area studies, and comparative politics. Creative organizational tools such as tags and keywords aid in navigation of the handbook to help readers trace disruptions, thematic connections, contrasts, and geographic affinities across entries.

The paper critically discusses the treatment of Russellian monism in Tomáš Hříbek’s monograph Jaké to je, nebo o čem to je? (What It’s Like, or What It’s About?). According to Hříbek, Russellian monism, the approach to phenomenal consciousness inspired by the insights of Bertrand Russell, is not a real alternative to materialism, dualism and idealism. I argue that Russellian monism, on the contrary, can be viewed as a self-standing philosophical position which, moreover, avoids the main problems of these traditional approaches. (...) I first address the objection that the fundamental entities of neutral monism have a mental, rather than neutral nature. In connection with neutral monism, I also express some worries concerning Hříbek’s via negativa definition of physicalism. Thereafter I explain why the causal closure of the physical which poses a serious difficulty for dualism is not a problem for Russellian monism and emphasize that Russellian monism is able to tackle challenges, such as the conceivability argument and the knowledge argument, better than materialism. While then Russellian monism has certain affinities with materialism, dualism and idealism, it avoids the most serious challenges for these approaches and we therefore have a good reason to view it as a self-standing and promising approach to phenomenal consciousness.

By illuminating the striking affinity between the most innovative aspects of postmodern thought and religious mystical discourse, Shadow of Spirit challenges the long established assumption that western thought is committed to nihilism. This collection of essays by internationally recognized scholars explores the implications of the fascination with the "sacred," "divine" or "infinite" which characterizes much contemporary thought. It shows how these concerns have surfaced in the work of Derrida, Baudrillard, Lyotard, Kristeva, Irigaray and others. Examining the connection between this postmodern (...) "turn" and the current search for a new discourse of ethics and politics, it also stresses the contribution made by feminist thought to this unexpected intellectual direction. (shrink)

While there are interesting connections between literature and evil, there is as of yet no systematic collection of models of evil to study literature. This is problematic, since literature is among other things an evaluative discourse and the most basic evaluative category is the polarity of good versus evil. In addition, evil shows important affinities with basic narratological principles. To initiate a discussion of models of evil for the analysis of literature, this article organizes a dozen models of evil (...) into four groups. The first consists of a core model which coincides with basic narratological elements in character analysis and narrative tension. The second group contains two pre-modern models of evil, defilement and moral-natural evil. The third group takes its cue from personality theory and proposes the five-factor model of personality and an enriched “dark triad,” and, to balance description against narration, a model which categorizes kinds of murder. The last group organizes six models around the thematic opposition between nature and society, an opposition which forms the backbone of Western philosophy and narrative. To test their validity, the models are applied to a series of literary examples/characters, above all Grendel, Browning’s “My Last Duchess,” and Carol Oates’ short story “Heat.”. (shrink)

This article presents a simple derivation of optimization models for reaction networks leading to a generalized form of the mass-action law, and compares the formal structure of Minimum Information Divergence, Quadratic Programming and Kirchhoff type network models. These optimization models are used in related articles to develop and illustrate the operation of ontology alignment algorithms and to discuss closely connected issues concerning the epistemological and statistical significance of sharp or precise hypotheses in empirical science.
