In his 1972 essay “The Incapacity for Conversation” (“Die Unfähigkeit zum Gespräch”) Gadamer takes up the question of whether changes in society have made it such that we are losing our ability to participate in dialogue. By the end of the essay he argues that this is not the case and that the claim that someone is incapable of dialogue is merely an excuse for not listening to the other person. Over the course of the essay Gadamer provides a clarification (...) of what exactly counts as a conversation and of how conversation is connected to friendship. (shrink)
Recent clinical trials show that psychedelics such as LSD and psilocybin can be given safely in controlled conditions, and can cause lasting psychological benefits with one or two administrations. Supervised psychedelic sessions can reduce symptoms of anxiety, depression, and addiction, and improve well-being in healthy volunteers, for months or even years. But these benefits seem to be mediated by "mystical" experiences of cosmic consciousness, which prompts a philosophical concern: do psychedelics cause psychological benefits by inducing false or implausible beliefs about (...) the metaphysical nature of reality? This book is the first scholarly monograph in English devoted to the philosophical analysis of psychedelic drugs. Its central focus is the apparent conflict between the growing use of psychedelics in psychiatry and the philosophical worldview of naturalism. Within the book, Letheby integrates empirical evidence and philosophical considerations in the service of a simple conclusion: this "Comforting Delusion Objection" to psychedelic therapy fails. While exotic metaphysical ideas do sometimes come up, they are not, on closer inspection, the central driver of change in psychedelic therapy. Psychedelics lead to lasting benefits by altering the sense of self, and changing how people relate to their own minds and lives-not by changing their beliefs about the ultimate nature of reality. The upshot is that a traditional conception of psychedelics as agents of insight and spirituality can be reconciled with naturalism (the philosophical position that the natural world is all there is). Controlled psychedelic use can lead to genuine forms of knowledge gain and spiritual growth-even if no Cosmic Consciousness or transcendent divine Reality exists. Philosophy of Psychedelics is an indispensable guide to the literature for researchers already engaged in the field of psychedelic psychiatry, and for researchers-especially philosophers-who want to become acquainted with this increasingly topical field.

Sciabarra replies to the seven respondents to his Fall 2002 essay on Rand, Rush, and progressive rock music. He defends the view that Rand's dialectical orientation underlies a fundamentally radical perspective. Rand shared with the counterculture—especially its libertarian progressive rock representatives—a repudiation of authoritarianism, while embracing the "unknown ideal" of capitalism. Her ability to trace the interrelationships among personal, cultural, and structural factors in social analysis and her repudiation of false alternatives is at the heart of that ideal vision, which (...) transcends left and right.

While many are born into prosperity, hundreds of millions of people lead lives of almost unimaginable poverty. Our world remains hugely unequal, with our place of birth continuing to exert a major influence on our opportunities. -/- In this accessible book, leading political theorist Chris Armstrong engagingly examines the key moral and political questions raised by this stark global divide. Why, as a citizen of a relatively wealthy country, should you care if others have to make do with less? (...) Do we have a moral duty to try to rectify this state of affairs? What does 'global justice' mean anyway - and why does it matter? Could we make our world a more just one even if we tried? Can you as an individual make a difference? -/- This book powerfully demonstrates that global justice is something we should all be concerned about, and sketches a series of reforms that would make our divided world a fairer one. It will be essential introductory reading for students of global justice, activists and concerned citizens. (shrink)

This book examines the hypothesis of "direct compositionality", which requires that semantic interpretation proceed in tandem with syntactic combination. Although associated with the dominant view in formal semantics of the 1970s and 1980s, the feasibility of direct compositionality remained unsettled, and more recently the discussion as to whether or not this view can be maintained has receded. The syntax-semantics interaction is now often seen as a process in which the syntax builds representations which, at the abstract level of logical form, (...) are sent for interpretation to the semantics component of the language faculty. In the first extended discussion of the hypothesis of direct compositionality for twenty years, this book considers whether its abandonment might have been premature and whether in fact direct compositionality is not after all a simpler and more effective conception of the grammar than the conventional account of the syntax-semantics interface in generative grammar. It contains contributions from both sides of the debate, locates the debate in the setting of a variety of formal theories, and draws on examples from a range of languages and a range of empirical phenomena.

This book takes concepts developed by researchers in theoretical computer science and adapts and applies them to the study of natural language meaning. Summarizing over a decade of research, Chris Barker and Chung-chieh Shan put forward the Continuation Hypothesis: that the meaning of a natural language expression can depend on its own continuation.
Mohism was an ancient Chinese philosophical movement founded in the fifth century B.C.E. by the charismatic artisan Mozi, or "Master Mo." The Mohists advanced a consequentialist ethics that anticipated Western utilitarianism by more than two thousand years and developed fascinating logical, epistemological, and political theories that set the terms of philosophical debate in China for generations. They were the earliest thinkers to outline a just war doctrine and to explain the origin of government from a state of nature. Their epistemology (...) and psychology provide intriguing alternatives to contemporary Western mentalism. The Philosophy of the Mozi is an extensive study of Mohism that immerses readers in the Mohist worldview, situates the movement's rise and decline within Chinese history, and highlights its relevance to modern thought.

There is a recent and growing trend in philosophy that involves deferring to the claims of certain disciplines outside of philosophy, such as mathematics, the natural sciences, and linguistics. According to this trend— deferentialism , as we will call it—certain disciplines outside of philosophy make claims that have a decisive bearing on philosophical disputes, where those claims are more epistemically justified than any philosophical considerations just because those claims are made by those disciplines. Deferentialists believe that certain longstanding philosophical problems (...) can be swiftly and decisively dispatched by appeal to disciplines other than philosophy. In this paper we will argue that such an attitude of uncritical deference to any non-philosophical discipline is badly misguided. With reference to the work of John Burgess and David Lewis, we consider deference to mathematics. We show that deference to mathematics is implausible and that main arguments for it fail. With reference to the work of Michael Blome-Tillmann, we consider deference to linguistics. We show that his arguments appealing to deference to linguistics are unsuccessful. We then show that naturalism does not entail deferentialism and that naturalistic considerations even motivate some anti-deferentialist views. Finally, we set out deferentialism’s failings and present our own anti-deferentialist approach to philosophical inquiry. (shrink)
States claim the right to choose who can come to their country. They put up barriers and expose migrants to deadly journeys. Those who survive are labelled ‘illegal’ and find themselves vulnerable and unrepresented. The international state system advantages the lucky few born in rich countries and locks others into poor and often repressive ones. In this book, Christopher Bertram skilfully weaves a lucid exposition of the debates in political philosophy with original insights to argue that migration controls must be (...) justifiable to everyone, including would-be and actual immigrants. Until justice prevails, states have no credible right to exclude and no-one is obliged to obey their immigration rules. Bertram’s analysis powerfully cuts through the fog of political rhetoric that obscures this controversial topic. It will be essential reading for anyone interested in the politics and ethics of migration. (shrink)
In this précis I summarise the main ideas of my book Philosophy of Psychedelics. The book discusses philosophical issues arising from the therapeutic use of “classic” psychedelic drugs such as psilocybin and LSD. The book is organised around what I call the Comforting Delusion Objection to psychedelic therapy: the concern that this novel and promising treatment relies essentially on the induction of non-naturalistic metaphysical beliefs, rendering it epistemically objectionable. I begin the précis by summarizing material from chapters two and three (...) of the book, which review evidence for the therapeutic efficacy of psychedelics, and the facts about their clinical use that prompt the Comforting Delusion Objection. I then summarize materials from chapters four and five of the book, which argue that psychedelic therapy works neither by experience-independent processes of neuroplasticity, nor by inducing non-naturalistic metaphysical ideations, but by altering mental representations of the self. Next, I summarise the specific, speculative account of how this might work that is developed in chapters six and seven of the book. This account is based on the predictive processing theory of brain function and the self-binding theory of self-representation. Chapters eight and nine of the book argue, on the basis of this account, that psychedelic therapy can have significant epistemic and spiritual benefits that are compatible with a naturalistic worldview. I summarize this material, and then, finally, the overall conclusions about psychedelic therapy drawn in the tenth and final chapter of the book. (shrink)
The (moral) permissibility of an act is determined by the relative weights of reasons, or so I assume. But how many weights does a reason have? Weight Monism is the idea that reasons have a single weight value. There is just the weight of reasons. The simplest versions hold that the weight of each reason is either weightier than, less weighty than, or equal to every other reason. We’ll see that this simple view leads to paradox in at least two (...) ways. We must complicate the picture somehow. I consider two candidate complications. The first, Parity Monism, is inspired by Ruth Chang’s suggestion that parity is a fourth comparative beyond the traditional three (>, <, =). This view complicates the single weight relation by allowing that the weights of reasons can be on a par. Unfortunately, Parity Monism resolves only one of the two paradoxes that afflict simple versions of Weight Monism. To resolve both paradoxes, we need our second candidate complication, Weight Pluralism. This view holds that reasons have at least two weight values (e.g., justifying weight and requiring weight) and these two values aren’t always equivalent. Parity is no substitute for Pluralism.

How do we define religious experiences? And what would be the relationship with spiritual experiences? The author claims that the cognitive turn in science gives us new opportunities to map the territory of religion and spirituality. In line with other authors, he proposes a building block approach of cognitive mechanisms that can deal with questions regarding the specificity, origin, and complexity of religious experiences. Two concepts are presented that bridge the great divide which is presumed to exist between sciences that (...) study the brain and humanities, namely the encultured brain and predictive minds. In section three, six building blocks of the structure of religious experience are formulated. New in his approach is the unexpected possible as distinctive ground between normal experiences and what we consider spiritual and religious experiences. Finally, the author presents a critical reflection on his proposal and challenges for the road ahead. (shrink)
This book provides a systematic study of three foundational issues in the semantics of natural language that have been relatively neglected in the past few decades. focuses on the formal characterization of intensions, the nature of an adequate type system for natural language semantics, and the formal power of the semantic representation language proposes a theory that offers a promising framework for developing a computational semantic system sufficiently expressive to capture the properties of natural language meaning while remaining computationally tractable (...) written by two leading researchers and of interest to students and researchers in formal semantics, computational linguistics, logic, artificial intelligence, and the philosophy of language.

So what is feminism anyway? Why are all the experts so reluctant to give us a clear definition? Is it possible to make sense of the complex and often contradictory debates? In this concise and accessible introduction to feminist theory, Chris Beasley provides clear explanations of the many types of feminism. She outlines the development of liberal, radical and Marxist//socialist feminism, and reviews the more contemporary influences of psychoanalysis, postmodernism, theories of the body, queer theory, and attends to the (...) ongoing significance of race and ethnicity. Given the diversity of feminist ideas, Chris Beasley a number of ways of looking at feminist theory and offer an open-ended approach which allows for variety and change. What is Feminism? is a clear and up-to-date guide to Western feminist theory for students, their teachers, researchers and anyone else who wants to understand and engage in current feminist debates. `Over the last three decades feminist theories and methodologies have become an increasingly complex as well as somewhat fraught terrain where ideas and egos alternately clash productively and destructively. This is an up-to-date and intelligent introduction to a field which remains a vital component of contemporary sociopolitical issues and debates' - Sneja Gunew, Professor of English and Women’s Studies, University of British Columbia.

In their recent article “A Hierarchy of Classical and Paraconsistent Logics”, Eduardo Barrio, Federico Pailos and Damien Szmuc present novel and striking results about meta-inferential validity in various three valued logics. In the process, they have thrown open the door to a hitherto unrecognized domain of non-classical logics with surprising intrinsic properties, as well as subtle and interesting relations to various familiar logics, including classical logic. One such result is that, for each natural number n, there is a logic which (...) agrees with classical logic on tautologies, inferences, meta-inferences, meta-meta-inferences, meta-meta-...-meta-inferences, but that disagrees with classical logic on n + 1-meta-inferences. They suggest that this shows that classical logic can only be characterized by defining its valid inferences at all orders. In this article, I invoke some simple symmetric generalizations of BPS’s results to show that the problem is worse than they suggest, since in fact there are logics that agree with classical logic on inferential validity to all orders but still intuitively differ from it. I then discuss the relevance of these results for truth theory and the classification problem. (shrink)
Good theory; bad politics - this is how Zizek's works have been described. Now Chris McMillan argues that Zizek's reading of global capitalism could reinvent political subversion. He highlights the political consequences of Zizek's fundamental concepts, such as the Lacanian Real, universality and the communist hypothesis. He argues that Zizek's turn to Communism represents the ultimate significance of Zizek's work for the 21st century and a marked new direction for Zizekian theory. While Zizek's work attracts a lot of labels, (...) most of them pejorative - communist, conservative, anti-semantic - Chris McMillan identifies Zizek's unique and productive contribution to social and political theory, constructing his work as a response to the difficulties of contemporary social theory and the political deadlock of global capitalism.

Open-minded people should endorse dogmatism because of its explanatory power. Dogmatism holds that, in the absence of defeaters, a seeming that P necessarily provides non-inferential justification for P. I show that dogmatism provides an intuitive explanation of four issues concerning non-inferential justification. It is particularly impressive that dogmatism can explain these issues because prominent epistemologists have argued that it can’t address at least two of them. Prominent epistemologists also object that dogmatism is absurdly permissive because it allows a seeming to (...) provide justification even if the seeming was caused in some apparently inappropriate way. I conclude by disarming this objection. (shrink)
Struggles over precious resources such as oil, water, and land are increasingly evident in the contemporary world. States, indigenous groups, and corporations vie to control access to those resources, and the benefits they provide. These conflicts are rapidly spilling over into new arenas, such as the deep oceans and the Polar regions. How should these precious resources be governed, and how should the benefits and burdens they generate be shared? Justice and Natural Resources provides a systematic theory of natural resource (...) justice. It argues that we should use the benefits and burdens flowing from these resources to promote greater equality across the world, and share governance over many important resources. At the same time, the book takes seriously the ways in which particular resources can matter in peoples lives. It provides invaluable guidance on a series of pressing issues, including the scope of state resource rights, the claims of indigenous communities, rights over ocean resources, the burdens of conservation, and the challenges of climate change and transnational resource governance. It will be required reading for anyone interested in natural resource governance, climate politics, and global justice. (shrink)
The primary aim of this book is to understand how seemings relate to justification and whether some version of dogmatism or phenomenal conservatism can be sustained. It also addresses a number of other issues, including the nature of seemings, cognitive penetration, Bayesianism, and the epistemology of morality and disagreement.
It is natural to think that many of our beliefs are rational because they are based on seemings, or on the way things seem. This is especially clear in the case of perception. Many of our mathematical, moral, and memory beliefs also appear to be based on seemings. In each of these cases, it is natural to think that our beliefs are not only based on a seeming, but also that they are rationally based on these seemings—at least assuming there (...) is no relevant counterevidence. This piece is an introduction to a volume dedicated to the question of what the connection is between seemings and justified belief: under what conditions, if any, can a seeming justify its content?

This paper is an enquiry into the logical, metaphysical, and physical possibility of time travel understood in the sense of the existence of closed worldlines that can be traced out by physical objects. We argue that none of the purported paradoxes rule out time travel either on grounds of logic or metaphysics. More relevantly, modern spacetime theories such as general relativity seem to permit models that feature closed worldlines. We discuss, in the context of Gödel's infamous argument for the ideality (...) of time based on his eponymous spacetime, what this apparent physical possibility of time travel means. Furthermore, we review the recent literature on so-called time machines, i.e., of devices that produce closed worldlines where none would have existed otherwise. Finally, we investigate what the implications of the quantum behaviour of matter for the possibility of time travel might be and explicate in what sense time travel might be possible according to leading contenders for full quantum theories of gravity such as string theory and loop quantum gravity.

Building upon his previous books about Marx, Hayek, and Rand, _Total Freedom_ completes what _Lingua Franca_ has called Sciabarra’s "epic scholarly quest" to reclaim dialectics, usually associated with the Marxian left, as a methodology that can revivify libertarian thought.

Part Two investigates in detail the work of Murray Rothbard as a leading modern libertarian, in whose thought Sciabarra finds both dialectical and nondialectical elements. (...) Ultimately, Sciabarra aims for a dialectical-libertarian synthesis, highlighting the need to think of the "totality" of interconnections in a dynamic system as the way to ensure human freedom while avoiding "totalitarianism".

Users of psychedelic drugs often report that their sense of being a self or ‘I’ distinct from the rest of the world has diminished or altogether dissolved. Neuroscientific study of such ‘ego dissolution’ experiences offers a window onto the nature of self-awareness. We argue that ego dissolution is best explained by an account that explains self-awareness as resulting from the integrated functioning of hierarchical predictive models which posit the existence of a stable and unchanging entity to which representations are bound. (...) Combining recent work on the ‘integrative self' and the phenomenon of self-binding with predictive processing principles yields an explanation of ego dissolution according to which self-representation is a useful Cartesian fiction: an ultimately false representation of a simple and enduring substance to which attributes are bound which serves to integrate and unify cognitive processing across levels and domains. The self-model is not a mere narrative posit, as some have suggested; it has a more robust and ubiquitous cognitive function than that. But this does not mean, as others have claimed, that the self-model has the right attributes to qualify as a self. It performs some of the right kinds of functions, but it is not the right kind of entity. Ego dissolution experiences reveal that the self-model plays an important binding function in cognitive processing, but the self does not exist. (shrink)

Traditional debates, such as those regarding whether the universe is finite in spatial or temporal extent, exemplified, according to Kant, the inherent tendency of pure reason to lead us astray. Although various aspects of Kant’s arguments fail to find a footing in modern cosmology, Kant’s objections to the search for a complete objective description of the cosmos are related to three intertwined issues that are still of central importance: the applicability of universal laws, the status of distinctively cosmological laws, and (...) the explanatory sufficiency of laws. We will advocate a broadly Kantian position on these three issues as part of a critical response to a prevalent strain of Leibnizian rationalism in contemporary cosmology. (shrink)
Ethical or ‘socially sustainable’ sourcing mechanisms mandating labour standards among the suppliers and subcontractors that organisations source goods and services from are becoming more common. The issue of how labour activist groups such as trade unions can encourage organisations to adopt and strengthen these mechanisms within domestic production networks is largely unexplored. Using three cases of domestic sustainable sourcing campaigns developed by unions in Britain, the strategies used by labour activists, the characteristics of the organisations targeted and the motivations of (...) lead firms for improving sourcing practices are analysed. The article makes a significant contribution by demonstrating that organisational susceptibility to reputational risk is a key factor influencing the capacity of activist groups to convince and compel their targets to improve sourcing practices. It argues that different types of organisations are susceptible to reputational damage in different ways, that risk events provide opportunities for unions to strengthen their leverage against target organisations, and that the multidimensional nature of corporate reputation needs to be better considered for understanding how campaigns are framed and executed.

Psychedelic ingestion and meditative practice are both ancient methods for altering consciousness that became widely known in Western society in the second half of the 20th century. Do the similarities begin and end there, or do these methods – as many have claimed over the years – share some deeper common elements? In this chapter I take a neurophilosophical approach to this question and argue that there are, indeed, deeper commonalities. Recent empirical studies show that psychedelics and meditation modulate overlapping (...) brain networks involved in the sense of self, salience, and attention; moreover, psychedelics can occasion lasting increases in “mindfulness-related capacities” for taking a non-reactive stance on one’s inner experience (e.g. Sampedro et al. 2017). The self-binding theory of psychedelic ego dissolution (Letheby and Gerrans 2017) offers a plausible explanation of these findings: by disrupting self-related beliefs implemented in high-level cortical networks, both psychedelics and meditation can “unbind” mental contents from one’s self-model, moving these contents along the continuum from phenomenal transparency to opacity (cf. Metzinger 2003). In other words, both psychedelics and meditation can expose and weaken our foundational beliefs about our own identity, allowing us to disidentify with these beliefs and see them as “just thoughts”. There are connections between these ideas and recent arguments suggesting that psychedelic use may have epistemic benefits consistent with philosophical naturalism (Letheby 2015, 2016, 2019). I conclude with a proposal: these connections may help in thinking about the putative epistemic benefits of meditation practice from a naturalistic perspective. (shrink)
In his wide-ranging study of architecture and cultural evolution, Chris Abel argues that, despite progress in sustainable development and design, resistance to changing personal and social identities shaped by a technology-based and energy-hungry culture is impeding efforts to avert drastic climate change. The book traces the roots of that culture to the coevolution of Homo sapiens and technology, from the first use of tools as artificial extensions of the human body to the motorized cities spreading around the world, whose (...) uncontrolled effects are fast changing the planet itself. Advancing a new concept of the meme, called the 'technical meme', as the primary agent of cognitive extension and technical embodiment, Abel proposes a theory of the 'extended self' as a complex and diffuse outcome of that coevolution. Challenging conventional ideas of the self as a separate and autonomous being, the extended self, he explains, encompasses material and spatial as well as psychological and social elements, including the built environment and artifacts, and now reaches out into the virtual world of cyberspace. Drawing upon research into extended cognition and embodied minds from philosophy, psychology and the neurosciences, the book presents a new approach to environmental and cultural studies. N.B.

The Neo-Moorean Deduction (I have a hand, so I am not a brain-in-a-vat) and the Zebra Deduction (the creature is a zebra, so isn’t a cleverly disguised mule) are notorious. Crispin Wright, Martin Davies, Fred Dretske, and Brian McLaughlin, among others, argue that these deductions are instances of transmission failure. That is, they argue that these deductions cannot transmit justification to their conclusions. I contend, however, that the notoriety of these deductions is undeserved. My strategy is to clarify, attack, defend, (...) and apply. I clarify what transmission and transmission failure really are, thereby exposing two questionable but quotidian assumptions. I attack existing views of transmission failure, especially those of Crispin Wright. I defend a permissive view of transmission failure, one which holds that deductions of a certain kind fail to transmit only because of premise circularity. Finally, I apply this account to the Neo-Moorean and Zebra Deductions and show that, given my permissive view, these deductions transmit in an intuitively acceptable way—at least if either a certain type of circularity is benign or a certain view of perceptual justification is false.
