Eric Cunnigham's exciting new book combines a new translation of the Chinese classic Daodejing with a synthetic interpretation of the Dao. It innovatively employs the interweaving perspectives of Anthroposophy and esoteric world history. Among the inspirations for this work's unique reading of the verses of the *Daodejing*is the speculation of contemporary esoteric scholars that the Yellow Emperor of Chinese mytho-history was actually a human incarnation of the spirit known elsewhere as Lucifer. This argument has been used to explain the (...) manner in which "demigods" introduced themselves to the earthly sphere in order to manipulate human history. This theory resonates with the theological claims of Genesis 6: the notion that fallen angels infiltrated the human world is a contributing element to numerous theories regarding the establishment of ruling classes and elite bloodlines in history. Cunningham considers these claims from the standpoint of esoteric history and evaluates them on the basis of their convergence with kindred concepts (such as Zen illumination, mysticism, and the simulation hypothesis), to show the operations and implications of Gnosticism in history. The book makes a bold case for this common thread in various "all is consciousness" theories of Mind, from Plato, through the ancient skeptics, to Daoism, Zen, and even to the idealism of the 1960s, leading to directly to postmodern theories of "digital consciousness." What philosophers are exploring today through such topics as virtual reality and digital simulation are presented as new ways of discussing the same contours of reality hinted at in the *Daodejing*. Rather than leading us to a more humanistic vision of reality, as the Daoist scholars traditionally maintain, this theory of mind may lie at the bottom of a systematic anti-humanist impulse that has operated throughout world history.

More than 30 years ago in Annals of Science, Dr. Eric Forbes of the University of Edinburgh published the correspondence between Carl Gauss and Great Britain's Astronomer Royal, Nevil Maskelyne. Five of the letters he listed as missing have now been discovered, along with two entirely new letters he was unaware of. Their nearly complete correspondence can now be read for the first time in 200 years.

Jennifer Hornsby has defended the Reasons-Knowledge Thesis : the claim that \-ing because p requires knowing that p, where the ‘because’ at issue is a rationalising ‘because’. She defends by appeal to the thought that it provides the best explanation of why the subject in a certain sort of Gettier case fails to be in a position to \ because p. Dustin Locke and, separately, Nick Hughes, present some modified barn-façade cases which seem to constitute counterexamples to and undermine Hornsby’s (...) way of motivating it by rendering their alternative Reasons-Explanation Thesis a better explanation of Hornsby’s datum. This paper defends and Hornsby’s argument for it against those objections. First, I point out that their supposedly intuitive verdict about the relevant barn-façade cases is not as intuitive as they think. Second, I point out that even if we share the intuition: we have strong reason to doubt the verdict anyway. And finally, I point out that since is independently implausible, the two problems can be tackled anyway. (shrink)

Nihilism is the logic of nothing as something, which claims that Nothing Is. Its unmaking of things, and its forming of formless things, strain the fundamental terms of existence: what it is to be, to know, to be known. But nihilism, the antithesis of God, is also like theology. Where nihilism creates nothingness, condenses it to substance, God also makes nothingness creative. Negotiating the borders of spirit and substance, theology can ask the questions of nihilism that other disciplines do not (...) ask: Where is it? What is it made of? Why is it so destructive? How can it be made holy, or overcome? Genealogy of Nihilism rereads Western history in the light of nihilistic logic, which pervades two millennia of Western thought and is coming to fruition in our present age in a virulently dangerous manner. From Parmenides to Alain Badiou, via Plotinus, Avicenna, Duns Scotus, Ockham, Descartes, Spinoza, Kant, Hegel, Heidegger, Sartre, Lacan, Deleuze and Derrida, a genealogy of nothingness can be witnessed in development, with devastating consequences for the way we live. Conor Cunningham's elaborate and sophisticated theology, spanning the disciplines of philosophy, science and popular culture, permits us to see not simply how modernity has formulated its philosophies of nothing, but how these philosophies might be transfigures by the crucial difference theology makes, and so be reconcilable with life and the living - with the very gift which being is.

Can large language models produce expert‐quality philosophical texts? To investigate this, we fine‐tuned GPT‐3 with the works of philosopher Daniel Dennett. To evaluate the model, we asked the real Dennett 10 philosophical questions and then posed the same questions to the language model, collecting four responses for each question without cherry‐picking. Experts on Dennett's work succeeded at distinguishing the Dennett‐generated and machine‐generated answers above chance but substantially short of our expectations. Philosophy blog readers performed similarly to the experts, while ordinary (...) research participants were near chance distinguishing GPT‐3's responses from those of an “actual human philosopher”.

In this article, I argue for an historical understanding of the relationship between ideology and utopia/utopianism that positions the latter as a specifically modern compensation for the loss of the cosmologically grounded, unitary ideology supplied by the late medieval Christian Church. This claim relies upon but revises Fredric Jameson’s early theorization of the collaboration between ideology and utopia/utopianism, which emphasizes that utopian elements allow ideology to offer subjects a ‘compensatory exchange’ for their complicity. Developing my central argument requires considering the (...) current viability of the ‘secularization thesis’, which classically associated modernization with secularization but which has undergone heavy criticism and revision by social scientists over the past half-century. These theoretical discussions, finally, are couched within a critical appraisal of the status of utopianism in contemporary politics. (shrink)

Summary A provocative examination of the consequences of Levinas’s and Adorno’s thought for contemporary ethics and political philosophy. This book sets up a dialogue between Emmanuel Levinas and Theodor W. Adorno, using their thought to address contemporary environmental and social-political situations. Eric S. Nelson explores the “non-identity thinking” of Adorno and the “ethics of the Other” of Levinas with regard to three areas of concern: the ethical position of nature and “inhuman” material others such as environments and animals; the (...) bonds and tensions between ethics and religion and the formation of the self through the dynamic of violence and liberation expressed in religious discourses; and the problematic uses and limitations of liberal and republican discourses of equality, liberty, tolerance, and their presupposition of the private individual self and autonomous subject. Thinking with and beyond Levinas and Adorno, this work examines the possibility of an anarchic hospitality and solidarity between material others and sensuous embodied life. “This is an extremely impressive, original, and thorough treatment of two key twentieth-century thinkers and their applicability to the most pressing social and political issues of our time.” — Jeffrey A. Bernstein, author of Leo Strauss on the Borders of Judaism, Philosophy, and History “This book is an excellent and timely contribution to political and environmental philosophy, located around a nuanced historical and philosophical approach to Levinas and Adorno. It will be of great interest to anyone concerned with these figures or with the current moment.” — Martin Shuster, author of Autonomy after Auschwitz: Adorno, German Idealism, and Modernity.

An important function of the self is to identify external objects that are potentially personally relevant. We suggest that such objects may be identified through mere ownership. Extant research suggests that encoding information in a self-relevant context enhances memory , thus an experiment was designed to test the impact of ownership on memory performance. Participants either moved or observed the movement of picture cards into two baskets; one of which belonged to self and one which belonged to another participant. A (...) subsequent recognition test revealed that there was a significant memory advantage for objects that were owned by self. Acting on items had no impact on memory. Results are discussed with reference to the importance of self-object associations in cognition. (shrink)

Daoism and Environmental Philosophy explores ethics and the philosophy of nature in the Daodejing, the Zhuangzi, and related texts to elucidate their potential significance in our contemporary environmental crisis. This book traces early Daoist depictions of practices of embodied emptying and forgetting and communicative strategies of undoing the fixations of words, things, and the embodied self. These are aspects of an ethics of embracing plainness and simplicity, nourishing the asymmetrically differentiated yet shared elemental body of life of the myriad things, (...) and being responsively attuned in encountering and responding to things. These critical and transformative dimensions of early Daoism provide exemplary models and insights for cultivating a more expansive ecological ethos, environmental culture of nature, and progressive political ecology. This work will be of interest to students and scholars interested in philosophy, environmental ethics and philosophy, religious studies, and intellectual history. (shrink)

Arguments from disagreement against moral realism begin by calling attention to widespread, fundamental moral disagreement among a certain group of people. Then, some skeptical or anti-realist-friendly conclusion is drawn. Chapter 2 proposes that arguments from disagreement share a structure that makes them vulnerable to a single, powerful objection: they self-undermine. For each formulation of the argument from disagreement, at least one of its premises casts doubt either on itself or on one of the other premises. On reflection, this shouldn’t be (...) surprising. These arguments are intended to support very strong metaphysical or epistemological conclusions about morality. They must therefore employ very strong metaphysical or epistemological premises. But, given the pervasiveness of disagreement in philosophy, especially about metaphysics and epistemology, very strong premises are virtually certain to be the subject of widespread, intractable disagreement—precisely the sort of disagreement that proponents of these arguments think undermine moral claims. Thus, these arguments undermine their own premises. If Chapter 2’s argument is sound, it provides realists with a single, unified strategy for responding to any existing or forthcoming arguments from disagreement. (shrink)

“What is the structure of thought?” is as central a question as any in cognitive science. A classic answer to this question has appealed to a Language of Thought (LoT). We point to emerging research from disparate branches of the field that supports the LoT hypothesis, but also uncovers diversity in LoTs across cognitive systems, stages of development, and species. Our letter formulates open research questions for cognitive science concerning the varieties of rules and representations that underwrite various LoT-based systems (...) and how these variations can help researchers taxonomize cognitive systems.

ABSTRACT: In memory of Professor Louise Marcil, from the University of Montreal, who died prematurely in April 1995, this special issue of Dialogue is dedicated to Equality. In addition to presenting the various contributions, the Introduction traces the main strands of Louise Marcil’s work on equality. The impressive corpus of her writings on the subject is characterized throughout by sensitivity to the historical and conceptual complexity of egalitarian theories and policies and by a depth of scholarship, the richness of which (...) defies classification into traditional philosophical schools. Moreover, far from being merely abstract scholarship, this work was clearly intended to strengthen actual egalitarian social projects, to which Louise Marcil was passionately committed. The contributions to this special issue of Dialogue have been selected in large part to reflect the diversity and scholarly standards of Louise Marcil’s approach to equality as well as its engaged spirit.

For critical legal scholars, the ongoing far-right assault upon the liberal status quo poses a distinct dilemma. On the one hand, the desire to condemn the far-right is overwhelming. On the other hand, such condemnations are susceptible to being appropriated as a validation of the very liberalism that critical theorists have long questioned. In seeking to transcend this dilemma, my focus is on the discourse of ‘white genocide’ — a commonplace belief amongst the far-right/white nationalists that ‘whites’, as a discrete (...) group, are facing demographic destruction as a result of deliberate policy choices. Such a belief has motivated acts of extreme violence. While libel to dismissal by experts on mainstream understandings of genocide, namely international criminal lawyers, I argue that this ‘white genocide’ discourse deserves careful scrutiny as a jurisprudential and socio-legal phenomenon that reveals key weaknesses in present modalities of liberal justification. Drawing upon an array of recent critical theories, I show how a liberalism unable to face its own decline enables the very far-right assertions it purports to oppose. Thus, given liberalism’s failure to act as a neutral arbiter, an alternative approach for those opposing the far-right is to develop a vision of politics and society that confront believers in ‘white genocide’ on a more substantive level. This, I argue, forces the far-right’s opponents to disavow liberal scepticism towards utopian transformation as well as the juridical understandings and institutions that allow this scepticism to durably persist.

Contrary to Vaesen's argument that humans are unique with respect to nine cognitive capacities essential for tool use, we suggest that although such cognitive processes contribute to variation in tool use, it does not follow that these capacities arenecessaryfor tool use, nor that tool use shaped cognition per se, given the available data in cognitive neuroscience and behavioral biology.

In this wide-ranging and authoritative volume, leading scholars engage with the philosophy and writings of Wilhelm Dilthey, a key figure in nineteenth-century thought. Their chapters cover his innovative philosophical strategies and explore how they can be understood in relation to their historical situation, as well as presenting incisive interpretations of Dilthey's arguments, including their development, their content, and their influence on later thought. A key focus is on how Dilthey's work remains relevant to current debates around art and literature, the (...) biographical and autobiographical self, knowledge, language, science, culture, history, society, and psychology and the embodied mind. The volume will be important for researchers in hermeneutics, aesthetics, practical philosophy, and the history of German philosophy, providing a valuable introduction to Dilthey's work as well as detailed critical analysis of its ongoing significance.

Adam Smith was a famous economist and moral philosopher. This book treats Smith also as a systematic philosopher with a distinct epistemology, an original theory of the passions, and a surprising philosophy mind. The book argues that there is a close, moral connection between Smith's systematic thought and his policy recommendations.

I argue that Smith proposed a new kind of imperialism, which we would describe as a species of ‘federalism,’ and that his plan influenced Bentham and Kant in their federal projects, although they seem to have been unaware of each other’s proposals. In what follows, I outline Smith’s position. I then describe Kant’s and Bentham’s debts to Smith in turn. This will also allow for greater clarity about the nature of early liberalism.

According to the analysis of concessive conditionals suggested by Crupi and Iacona, a concessive conditional \(p{{\,\mathrm{\hookrightarrow }\,}}q\) is adequately formalized as a conjunction of conditionals. This paper presents a sound and complete axiomatic system for concessive conditionals so understood. The soundness and completeness proofs that will be provided rely on a method that has been employed by Raidl, Iacona, and Crupi to prove the soundness and completeness of an analogous system for evidential conditionals.

The Moral Foundations of Trust seeks to explain why people place their faith in strangers, and why doing so matters. Trust is a moral value that does not depend upon personal experience or on interacting with people in civic groups or informal socializing. Instead, we learn to trust from our parents, and trust is stable over long periods of time. Trust depends on an optimistic world view: the world is a good place and we can make it better. Trusting people (...) are more likely to give through charity and volunteering. Trusting societies are more likely to redistribute resources from the rich to the poor. Trust has been in decline in the United States for over 30 years. The roots of this decline are traceable to declining optimism and increasing economic inequality, which Uslaner supports by aggregate time series in the United States and cross-sectional data across market economies.

Do philosophy professors specializing in ethics behave, on average, any morally better than do other professors? If not, do they at least behave more consistently with their expressed values? These questions have never been systematically studied. We examine the self-reported moral attitudes and moral behavior of 198 ethics professors, 208 non-ethicist philosophers, and 167 professors in departments other than philosophy on eight moral issues: academic society membership, voting, staying in touch with one's mother, vegetarianism, organ and blood donation, responsiveness to (...) student emails, charitable giving, and honesty in responding to survey questionnaires. On some issues, we also had direct behavioral measures that we could compare with the self-reports. Ethicists expressed somewhat more stringent normative attitudes on some issues, such as vegetarianism and charitable donation. However, on no issue did ethicists show unequivocally better behavior than the two comparison groups. Our findings on attitude-behavior consistency were mixed: ethicists showed the strongest relationship between behavior and expressed moral attitude regarding voting but the weakest regarding charitable donation. We discuss implications for several models of the relationship between philosophical reflection and real-world moral behavior. (shrink)

Ethnic competition theory provides a powerful explanation for ethnic conflict, by demonstrating how variation in ethnic mobilization relates to intergroup struggles over scarce resources. However, the tendency to capture such relationships at the aggregate level, through macro-level proxies of intergroup competition, offers little insight into the processes through which ethnic grievances mobilize into contentious action. This article integrates insights from the social movements literature to address how competitive contexts crystallize into broader conflicts. Drawing on data from the civil rights-era Ku (...) Klux Klan—perhaps the quintessential case of contentious ethnic organization in the United States—the analysis focuses on the ways in which meso-level arrangements mediate the relationship between overarching competitive contexts and ethnic conflict. Results of a paired comparative analysis of KKK mobilization in Greensboro and Charlotte demonstrate that social and spatial relations within each city shaped the contours of perceived competition and subsequent ethnic organization in ways that were not always predictable through observation of conventional proxies of competition.

Christian realism is undergoing a renaissance in both American Christianity and around the world. Caught between globalist liberalism, on the one hand, and pragmatic realism on the other, Christians are in search of international ethics, a standard and tradition in foreign policy, that takes the two great books of life, the Christian Scriptures and the world we live in, seriously. This book is an extended, edited collection that mines the tradition of Christian realism in international relations and finds in it (...) voices and mentors urgently fresh for a new age. With classic authors like Reinhold Niebuhr, Herbert Butterfield, Paul Ramsey, and Jean Bethke Elshtain, and contemporaries like Marc LiVecche, Rebecca Heinrichs, and others, this collection offers for the first time an organization, periodization, and collection of primary Christian realist sources for the initiate and the expert in foreign relations."--Provided by publisher.

In _On Empirically Equivalent Systems of the World_ from 1975, Quine formulated a thesis of underdetermination roughly to the effect that every scientific theory has an empirically equivalent but logically incompatible rival, one that cannot be discarded merely as a terminological variant of the former. For Quine, the truth of this thesis was an open question. If true, some would argue that it undermines any belief in scientific theories that is based purely on their empirical success. But despite its potential (...) significance, surprisingly little has been done by way of establishing or refuting it. My aim is to establish the thesis for as large a class of theories as possible. Under various precisifications of the concepts involved, I show that it holds for all consistent and recursively axiomatizable theories that postulate infinitely many theoretical entities. (shrink)

It is widely held that every person is a person essentially, where being a person is having special mental properties such as intelligence and self-consciousness. It follows that nothing can acquire or lose these properties. The paper argues that this rules out all familiar psychological-continuity views of personal identity over time. It also faces grave difficulties in accounting for the mental powers of human beings who are not intelligent and self-conscious, such as foetuses and those with dementia.

Moral or ethical questions are vital because they affect our daily lives: what is the best choice we can make, the best action to take in a given situation, and ultimately, the best way to live our lives? Health ethics has contributed to moving ethics toward a more experience-based and user-oriented theoretical and methodological stance but remains in our practice an incomplete lever for human development and flourishing. This context led us to envision and develop the stance of a “living (...) ethics”, described in this inaugural collective and programmatic paper as an effort to consolidate creative collaboration between a wide array of stakeholders. We engaged in a participatory discussion and collective writing process known as instrumentalist concept analysis. This process included initial local consultations, an exploratory literature review, the constitution of a working group of 21 co-authors, and 8 workshops supporting a collaborative thinking and writing process. First, a living ethics designates a stance attentive to human experience and the role played by morality in human existence. Second, a living ethics represents an ongoing effort to interrogate and scrutinize our moral experiences to facilitate adaptation of people and contexts. It promotes the active and inclusive engagement of both individuals and communities in envisioning and enacting scenarios which correspond to their flourishing as authentic ethical agents. Living ethics encourages meaningful participation of stakeholders because moral questions touch deeply upon who we are and who we want to be. We explain various aspects of a living ethics stance, including its theoretical, methodological, and practical implications as well as some barriers to its enactment based on the reflections resulting from the collaborative thinking and writing process.

This paper explains Sophie de Grouchy’s philosophical debts to Adam Smith. I have three main reasons for this: first, it should explain why eighteenth-century philosophical feminists found Smith, who has—to put it mildly—not been a focus of much recent feminist admiration, a congenial starting point for their own thinking; second, it illuminates De Grouchy’s considerable philosophical originality, especially her important, overlooked contributions to political theory; third, it is designed to remove some unfortunate misconceptions that have found their way into Karin (...) Brown’s ‘Introduction’ to the recent and much-to-be-welcomed translation of Sophie de Grouchy’s Lettres Sur La Sympathie. While Brown claims that there are major ‘differences’ in their programs of ‘social reform’, I argue there are important commonalities between Smith and De Grouchy. In particular, I highlight how they share a common understanding of how human sensibilities are shaped by social institutions and I show that De Grouchy’s path-breaking analysis of negative and positive liberty is grounded in her extension of Smith’s political theory and moral psychology.

The core of this book is a novel theory of distributive justice premised on the fundamental moral equality of persons. In the light of this theory, Rakowski considers three types of problems which urgently require solutions-- the distribution of resources, property rights, and the saving of life--and provides challenging and unconventional answers. Further, he criticizes the economic analysis of law as a normative theory, and develops an alternative account of tort and property law.

Foundational theories of mental content seek to identify the conditions under which a mental representation expresses, in the mind of a particular thinker, a particular content. Normativists endorse the following general sort of foundational theory of mental content: A mental representation r expresses concept C for agent S just in case S ought to use r in conformity with some particular pattern of use associated with C. In response to Normativist theories of content, Kathrin Glüer-Pagin and Åsa Wikforss propose a (...) dilemma, alleging that Normativism either entails a vicious regress or falls prey to a charge of idleness. In this paper, I respond to this argument. I argue that Normativism can avoid the commitments that generate the regress and does not propose the sort of explanation required to charge that its explanation has been shown to be problematically idle. The regress-generating commitment to be avoided is, roughly, that tokened, contentful mental states are the product of rule-following. The explanatory task Normativists should disavow is that of explaining how it is that beliefs and other contentful mental states are produced. I argue that Normativism, properly understood as a theory of content, does not provide this kind of psychological explanation, and therefore does not entail that such explanations are to be given in terms of rule-following. If this is correct, Normativism is not the proper target of the dilemma offered by Glüer-Pagin and Wikforss. Understanding why one might construe Normativism in the way Glüer-Pagin and Wikforss must, and how, properly understood, it avoids their dilemma, can help us to appreciate the attractiveness of a genuinely normative theory of content and the importance of paying careful attention to the sort of normativity involved in norm-based theories of content.

There is not a uniform kind of consciousness common to all conscious mental states: beliefs, emotions, perceptual experiences, pains, moods, verbal thoughts, and so on. Instead, we need a distinction between phenomenal and nonphenomenal consciousness. As if consciousness simpliciter were not mysterious enough, philosophers have recently focused their worries on phenomenal consciousness, the kind that explains or constitutes there being "something it.

One of the deepest and longest-lasting debates in ethics concerns a version of the Euthyphro question: are choiceworthy things choiceworthy because agents have certain attitudes toward them or are they choiceworthy independent of any agents’ attitudes? Reasons internalists, such as Bernard Williams, Michael Smith, Mark Schroeder, Sharon Street, Kate Manne, Julia Markovits, and David Sobel answer in the first way. They think that all of an agent’s normative reasons for action are grounded in facts about that agent’s pro-attitudes (e.g., her (...) desires, valuing states, normative judgments). According to the most popular brand of internalism, idealizing internalism, an agent’s reasons are grounded, not in her actual pro-attitudes, but rather in what her pro-attitudes would be in suitably idealized conditions. Idealizing internalists presuppose that, for any agent with an irrational set of attitudes, there is one uniquely rational set that that agent would have if she were to undergo the relevant idealizing process. I argue that this assumption is false and that it raises two puzzles for idealizing internalism: one about the existence of practical reasons and another about their normative weight. I argue that idealizing internalists have an adequate solution to the first puzzle but not the second. Indeed, when they try to solve the second puzzle, they confront a dilemma. This second puzzle and the associated dilemma thus constitutes a powerful, but so far unnoticed, difficulty for idealizing internalism. (shrink)
