There has been increasing interest in recent years in the development of approaches to estimate causal effects when the number of potential confounders is prohibitively large. This growth in interest has led to a number of potential estimators one could use in this setting. Each of these estimators has different operating characteristics, and it is unlikely that one estimator will outperform all others across all possible scenarios. Coupling this with the fact that an analyst can never know which approach is (...) best for their particular data, we propose a synthetic estimator that averages over a set of candidate estimators. Averaging is widely used in statistics for problems such as prediction, where there are many possible models, and averaging can improve performance and increase robustness to using incorrect models. We show that these ideas carry over into the estimation of causal effects in high-dimensional scenarios. We show theoretically that averaging provides robustness against choosing a bad model, and show empirically via simulation that the averaging estimator performs quite well, and in most cases nearly as well as the best among all possible candidate estimators. Finally, we illustrate these ideas in an environmental wide association study and see that averaging provides the largest benefit in the more difficult scenarios that have large numbers of confounders.

In this paper we show that the Gupta-Belnap systems S# and S* are П12. Since Kremer has independently established that they are П12-hard, this completely settles the problem of their complexity. The above-mentioned upper bound is established through a reduction to countable revision sequences that is inspired by, and makes use of a construction of McGee.

The seventh edition of this pragmatic guide to determining right and wrong in the workplace is updated with new case studies and ancillary materials to combine stakeholder perspectives with a deep dive on workplace ethics issues. Using a unique stakeholder-based approach, this book takes business ethics out of the theory realm and provides practical ways to analyze any business decision. Including dozens of cases, Joseph Weiss looks beyond the impacts of ethical lapses on share price and profit to focus (...) on relationships between stakeholders, including individuals, groups, corporations, and governments. The new seventh edition includes seven new cases and ten new Point/Counterpoint exercises, which challenge students to argue both sides of a contemporary issue. It incorporates the latest research as well as updated cases dealing with recent scandals at organizations such as Boeing, Facebook, and Uber. Professors will have access to online support, including teaching notes, PowerPoint slides, and sample tests. The book is equipped with a step-by-step guide to implementing stakeholder analysis, tips to help students apply ethical principles in their personal and professional lives, and comprehensive coverage of employee workplace issues. Addressing relevant topics such as risk management, preferential hiring, and sexual harassment in conjunction with the digital divide, bribery, the environment, and more, Business Ethics, seventh edition explores ethical implications in today's increasingly interconnected global business environment.

In this paper we introduce the notion of a set algebra $\mathscr{S}$ satisfying a system $\mathscr{E}$ equations. After defining a notion of freeness for such algebras, we show that, for any system $\mathscr{E}$ of equations, set algebras that are free in the class of structures satisfying $\mathscr{E}$ exist and are unique up to a bisimulation. Along the way, analogues of classical set-theoretic and algebraic properties are investigated.

El concepto de "inmanencia" ha adquirido una creciente relevancia en el campo filosófico contemporáneo. Dos destacados pensadores franceses, Gilles Deleuze y Franfois Jullien, le han otorgado un lugar fundamental en sus investigaciones. El propósito de este artículo es indagar el diálogo, poco explorado aún, entre ambos autores. Nuestra hipótesis de trabajo propone los siguientes ejes de análisis: primero, comparamos los usos de la expresión "absolutización de la inmanencia", acuñada por el sinólogo a fin de relativizar la trascendencia en el pensamiento (...) chino y luego empleada por Deleuze en el marco de la creencia en este mundo. En segundo lugar, examinamos las críticas que Jullien le dirige a Deleuze respecto a la relación entre la filosofía y la sabiduría. En tercer lugar, confrontamos sus perspectivas divergentes sobre la inmanencia en tanto "plano" (Deleuze) y como "fondo" (Jullien). Finalmente, ponemos de manifiesto la dificultad presente en ambos autores para pensar la idea de inmanencia. The concept of "immanence" has acquired substantial relevance within the contemporary philosophical field. Two influential french thinkers, Gilles Deleuze and Franfois Jullien, have conferred this concept a fundamental standing in their research. The purpose of this work is to explore the dialogue between both authors as this exploration has not been concluded. Our hypothesis puts forward the following axes of analysis. First, we shall compare the usage of the expression "absolutization of immanence" coined by the sinologist in order to put in perspective the idea of transcendence in Chinese thought. This expression was then applied by Deleuze within the frame of the belief in this world. Second, we shall examine Jullien's critique of Deleuze concerning the relationship between Philosophy and Wisdom. Third, we shall confront the divergent perspectives on immanence: as "plane" (Deleuze) and as "buttom" (Jullien). Finally, we shall show the difficulty to ponder the idea of immanence in both authors. (shrink)

The purpose of this note is to acknowledge a gap in a previous paper, "The complexity of revision," and to provide a corrected version of the argument.

This book critically assesses arguments for the existence of the God of classical theism, develops an innovative account of objects’ persistence, and defends new arguments against classical theism. The authors engage the following classical theistic proofs: Aquinas’s First Way, Aquinas’s De Ente argument, and Feser’s Aristotelian, Neo-Platonic, Augustinian, Thomistic, and Rationalist proofs. The authors also provide the first systematic treatment of the ‘existential inertia thesis’. By connecting the thesis to relativity theory and recent developments in the philosophy of physics, and (...) by developing a variety of novel existential-inertia-friendly explanations of persistence, they mount a formidable new case against classical theistic proofs. Finally, they defend new arguments against classical theism based on abstract objects and changing divine knowledge. The text appeals to students, researchers, and others interested in classical theistic proofs, the existence and nature of God, and the ultimate explanations of persistence, change, and contingency.

While engaging in rich discussion, Conspiracy Theories analyzes current arguments and evidence while providing real-world examples so students can contextualize and visualize the debates. Each chapter addresses important current questions, provides conceptual tools, defines important terms, and introduces the appropriate methods of analysis.

The book combines philosophical exposition and legal analysis, and pays special attention to issues of tort law.

The aim of this article is to fill a certain gap in the assessment of relativism by drawing on Joseph Ratzinger’s (1927–2022) criticism of the normative transformation since Kant. During the Enlightenment, Natural Law was doubted as a cultural feature of Christianity that had no bearing on pluralist society. Consequently, this jurisprudential tradition underwent de-Hellenization and branched out in radical directions, the most decisive of which was Kant’s post-metaphysical system of natural values. Positivism and German Idealism attempted to restore (...) the unity of philosophy that Kant’s philosophy had disrupted. Yet even more influentially, in the nineteenth and twentieth centuries it was Marxism that relativized the doxological aspect of normativity by emphasizing the importance of praxis. Since philosophy became neither an exact science as Kant had conceived it to be, nor a practical programme for social justice as Marxism had promised, the Existentialists, and particularly Sartre, advocated a more radical philosophy of freedom. Ratzinger argues that despite the nuances of post-Kantian philosophy, Positivism, Existentialism, and Marxism failed to comprehend the human condition and that the positivist method resulted in an overwhelming relativism that has reduced normativity to a matter of correct procedures rather than regarding it as the foundation of the inviolable dignity of the human being.

The paper argues against the growing tendency to interpret Brentano’s conception of inner consciousness in self-representational terms. This trend has received support from the tendency to see Brentano as a forerunner of contemporary same-order theories of consciousness and from the view that Brentano models intransitive consciousness on transitive consciousness, such that a mental state is conscious insofar as it is aware of itself as an object. However, this reading fails to take into account the Brentanian concept of object, which is (...) ultimately derived from ancient and medieval philosophy, as well as the secondary, elusive character that Brentano attributes to inner perception. According to Brentano, we have an aspectual but transparent consciousness of transcendent objects, whereas our awareness of our own mental acts is always complete but incidental, and ultimately opaque. Reversing the relationship between intentionality and consciousness faces difficulties at the textual interpretative level, but also raises theoretical problems, for it risks treating Brentano’s theory of mind as a form of subjectivism and idealism.

This anthology of essays on the work of David Kaplan, a leading contemporary philosopher of language, sprang from a conference, "Themes from Kaplan," organized by the Center for the Study of Language and Information at Stanford University.

According to agent-based approaches to virtue ethics, the rightness of an action is a function of the motives which prompted that action. If those motives were morally praiseworthy, then the action was right; if they were morally blameworthy, the action was wrong. Many critics find this approach problematically insensitive to an act’s consequences, and claim that agent-basing fails to preserve the intuitive distinction between agent- and act-evaluation. In this article I show how an agent-based account of right action can be (...) made sensitive to an act’s consequences. According to the approach which I defend, an action is right just in case it realizes an agent’s morally praiseworthy motive. Conversely, an action is wrong just in case it realizes a morally blameworthy motive. Specifying act-evaluation in terms of the realization, rather than the expression, of an agent’s motives allows an agent-based approach to distinguish between agent- and act-evaluation. This is because an agent may act from a morally praiseworthy motive, but fail to realize that motive. Her action will therefore not have been the right one, despite its being the expression of morally praiseworthy motives. (shrink)

The logical status of abstraction principles, and especially Hume’s Principle, has been long debated, but the best currently availeble tool for explicating a notion’s logical character—permutation invariance—has not received a lot of attention in this debate. This paper aims to fill this gap. After characterizing abstraction principles as particular mappings from the subsets of a domain into that domain and exploring some of their properties, the paper introduces several distinct notions of permutation invariance for such principles, assessing the philosophical significance (...) of each.

In this paper, we explore Fregean metatheory, what Frege called the New Science. The New Science arises in the context of Frege’s debate with Hilbert over independence proofs in geometry and we begin by considering their dispute. We propose that Frege’s critique rests on his view that language is a set of propositions, each immutably equipped with a truth value (as determined by the thought it expresses), so to Frege it was inconceivable that axioms could even be considered to be (...) other than true. Because of his adherence to this view, Frege was precluded from the sort of metatheoretical considerations that were available to Hilbert; but from this, we shall argue, it does not follow that Frege was blocked from metatheory in toto. Indeed, Frege suggests in Die Grundlagen der Geometrie a metatheoretical method for establishing independence proofs in the context of the New Science. Frege had reservations about the method, however, primarily because of the apparent need to stipulate the logical terms, those terms that must be held invariant to obtain such proofs. We argue that Frege’s skepticism on this score is not warranted, by showing that within the New Science a characterization of logical truth and logical constant can be obtained by a suitable adaptation of the permutation argument Frege employs in indicating how to prove independence. This establishes a foundation for Frege’s metatheoretical method of which he himself was unsure, and allows us to obtain a clearer understanding of Frege’s conception of logic, especially in relation to contemporary conceptions.

This book covers the basic guidelines of Vittorio Benussi’s research during the period at Graz and at Padua. It does so in the light of a thorough study of his Nachlass. The book re-evaluates Benussi’s work as a historical piece, and shows how his work is still relevant today, especially in the areas of cognitive psychology and cognitive science. The volume deals with this original and ingenious - though largely ignored - scholar and discusses his work as a leading experimental (...) psychologist. Benussi’s contributions as discussed in this book were particularly relevant in the fields of visual and tactile perception, time perception, forensic psychology, hypnosis and suggestion, unconscious, and emotions. His classical papers are impressive in their originality, energy, range of approaches, experimental skill, the wealth of findings, and the quality of theoretical discussions. This book demonstrates that Benussi was ahead of his time and that his themes, experiments and research programmes are highly relevant to contemporary cognitive psychology. (shrink)

RESUMEN En este artículo abordamos la cuestión del poder en el pensamiento de Deleuze. Según nuestra hipótesis, no hay en su obra un único concepto de poder sino diferentes enfoques no incompatibles entre sí pero que no se dejan reducir a un solo punto de vista. Esta variedad de abordajes puede ser reunida alrededor de dos posiciones generales adoptadas por Deleuze: primero, tiende a relativizar su eficacia respecto de otros elementos más fundamentales, realzando así los límites o la impotencia del (...) poder; segundo, le quita valor con relación a otras entidades y procesos en los que deposita su apuesta filosófica. Nos proponemos desarrollar estas perspectivas a fin de ofrecer un panorama integral de una temática relevante de la filosofía política deleuziana. ABSTRACT In this article, we address the question of power in Deleuze's thinking. According to our hypothesis, there is not a single concept of power in his work, but different approaches not incompatible with each other but that cannot be reduced to a single point of view. This variety of approaches can be gathered around two general positions about power, adopted by Deleuze: first, he tends to relativize its effectiveness with respect to other more fundamental elements, thus enhancing the limits or impotence of power; second, he takes away value in relation to other entities and processes in which he places his philosophical commitment. We intend to develop these perspectives in order to offer a comprehensive overview of a relevant theme of Deleuzian political philosophy. (shrink)

Tras elaborar una versión de la Historia Universal motorizada por la producción deseante, Deleuze adoptó un viraje anti-historicista, desplazándose a los devenires no históricos y multiplicando perspectivas negativas sobre la historia. En el marco del debate entre quienes le adjudican posiciones exclusivamente anti-historicistas y quienes le atribuyen una filosofía de la historia o una metodología historicista, proponemos elucidar las críticas deleuzianas a la historia sirviéndonos de la distinción entre la historia como realidad objetiva y la disciplina histórica. Además, analizamos la (...) primacía otorgada a la filosofía sobre la historia a partir de su concepción del acontecimiento y su temporalidad. (shrink)

Frege's logicist program requires that arithmetic be reduced to logic. Such a program has recently been revamped by the "neologicist" approach of Hale and Wright. Less attention has been given to Frege's extensionalist program, according to which arithmetic is to be reconstructed in terms of a theory of extensions of concepts. This paper deals just with such a theory. We present a system of second-order logic augmented with a predicate representing the fact that an object x is the extension of (...) a concept C, together with extra-logical axioms governing such a predicate, and show that arithmetic can be obtained in such a framework. As a philosophical payoff, we investigate the status of the so-called Hume's Principle and its connections to the root of the contradiction in Frege's system. (shrink)

While second-order quantifiers have long been known to admit nonstandard, or interpretations, first-order quantifiers (when properly viewed as predicates of predicates) also allow a kind of interpretation that does not presuppose the full power-set of that interpretationgeneral” interpretations for (unary) first-order quantifiers in a general setting, emphasizing the effects of imposing various further constraints that the interpretation is to satisfy.

In line with earlier works, this article argues for a “continuist” interpretation of Brentano’s conception of intentionality. It maintains that Brentano’s conception of intentionality rests on a complex set of notions, which are reduced to a minimal core or applied more fully depending on the complexity of the mental phenomenon under consideration and perspective from which it is analyzed. The article positions this conceptual structure in relation to theories of objects developed within the framework of late- and Neo-Scholastic philosophy where, (...) since the psychic act can relate to its object in different ways, the different types and roles of objects must be distinguished. This theory of objects enables Brentano to reinterpret Aristoteles’s idea of the intentionality of mental phenomena in light of the commentaries and interpretations of Thomas Aquinas while also giving space to other medieval texts.

This paper presents a formalization of first-order arithmetic characterizing the natural numbers as abstracta of the equinumerosity relation. The formalization turns on the interaction of a nonstandard cardinality quantifier with an abstraction operator assigning objects to predicates. The project draws its philosophical motivation from a nonreductionist conception of logicism, a deflationary view of abstraction, and an approach to formal arithmetic that emphasizes the cardinal properties of the natural numbers over the structural ones.

It does not derive its authority, as many authors have supposed, from some logically prior discipline, whether physics, economics, or philosophy, these ultimately depend on law itself, in its fundamental expression of human intellect and purpose. Law, he holds, is inseparably connected to everything in the world that goes to make up personal identity and meaning.

The classic follow-up to the bestselling "The Crack in the Cosmic Egg " - Explains the process of acculturation and the mechanisms that create our self-limiting "cosmic egg" of consensus reality - Reveals how our biological development innately creates a "crack" in our cosmic egg--leaving a way to return to the unencumbered consciousness of childhood - Explores ways to discover and explore the "crack" to restore wholeness to our minds and reestablish our ability to create our own realities In this (...) classic follow-up to his bestselling "The Crack in the Cosmic Egg," Joseph Chilton Pearce explains the process of acculturation and the mechanisms that create our self-limiting "cosmic egg" of consensus reality. Laying the groundwork for his later classic "Magical Child," Pearce shows that we go through early childhood connecting with the world through our senses. With the development of language and the process of acculturation not only do our direct experiences of the world become much less vivid but our innate states of nonordinary consciousness become suppressed. Trapped in a specific cultural context--a "cosmic egg"--we are no longer able to have or even recognize mystical experiences not mediated by the limitations of our culture. Motivated primarily by a fear of death, our enculturation literally splits our minds and prevents us from living fully in the present. Drawing from Carlos Castaneda's writings about Don Juan and the sense of "body-knowing," Pearce explores the varieties of nonordinary consciousness that can help us return to the unencumbered consciousness of our infancy. He shows that just as we each create our own cosmic egg of reality through cultural conditioning, we also innately create a "crack" in that egg. Ultimately certain shifts in our biological development take place to offset acculturation, leaving an avenue of return to our primary state. Pearce examines the creation of the "egg" itself and ways to discover its inherent cracks to restore wholeness to our minds, release us from our fear of death, and reestablish our ability to create our own realities through imagination and biological transcendence.

We present an axiomatic approach for a class of finite, extensive form games of perfect information that makes use of notions like “rationality at a node” and “knowledge at a node.” We distinguish between the game theorist's and the players' own “theory of the game.” The latter is a theory that is sufficient for each player to infer a certain sequence of moves, whereas the former is intended as a justification of such a sequence of moves. While in general the (...) game theorist's theory of the game is not and need not be axiomatized, the players' theory must be an axiomatic one, since we model players as analogous to automatic theorem provers that play the game by inferring (or computing) a sequence of moves. We provide the players with an axiomatic theory sufficient to infer a solution for the game (in our case, the backwards induction equilibrium), and prove its consistency. We then inquire what happens when the theory of the game is augmented with information that a move outside the inferred solution has occurred. We show that a theory that is sufficient for the players to infer a solution and still remains consistent in the face of deviations must be modular. By this we mean that players have distributed knowledge of it. Finally, we show that whenever the theory of the game is group-knowledge (or common knowledge) among the players (i.e., it is the same at each node), a deviation from the solution gives rise to inconsistencies and therefore forces a revision of the theory at later nodes. On the contrary, whenever a theory of the game is modular, a deviation from equilibrium play does not induce a revision of the theory. (shrink)

This paper presents a bivalent extensional semantics for positive free logic without resorting to the philosophically questionable device of using models endowed with a separate domain of “non-existing” objects. The models here introduced have only one (possibly empty) domain, and a partial reference function for the singular terms (that might be undefined at some arguments). Such an approach provides a solution to an open problem put forward by Lambert, and can be viewed as supplying a version of parametrized truth non (...) unlike the notion of “truth at world” found in modal logic. A model theory is developed, establishing compactness, interpolation (implying a strong form of Beth definability), and completeness (with respect to a particular axiomatization). (shrink)

The tension between beauty and technology is evinced in the modern distinction within technē itself between technology and “fine art.” Yet while beauty,as Kant observes, is never a means to an end, neither is it an “end in itself.” Beauty points beyond itself while refusing subordination to human interests. Both its noninstrumentality and its self-transcending character I trace to the intrinsic necessity of the beautiful, which is essentially impersonal while paradoxically being an object of love. I suggest that we conceive (...) of beauty as an “anonymous voice,” and I relate the latter to Heidegger’s critique of modern technology as a projection upon nature of “resource being.” I conclude that technology can be creative rather than destructive of beauty when it lets natural ends, which are inescapably in conflict with one another, transcend themselves through self-sacrifice.

Caregiving relationships are often characterized by an imbalance of power between the caregiver and her cared-for. The danger that this power will be abused is a source of serious moral concern. In this article, I argue that the risk of an abuse of power sometimes stems not from the possession of power itself, but from the very nature of caring relationships. This is because carers must be prepared to exercise non-minimal amounts of power over their cared-fors, even if doing so (...) is likely to cause the cared-for distress or even pain. This means that caring itself, rather than the malign influence of power dynamics, generates a risk of unintentional abuse. One of the ways in which this risk can be reduced, I argue, is by trying to avoid an exclusive focus on the outcomes of care, and by paying more attention to the way in which that care is delivered.
