In her reply to Baylis the author takes the opportunity to “clarify, and in some cases to correct, some facts”I am pleased to see Dr Baylis’s article relating to the Olivieri case at the Hospital for Sick Children and the University of Toronto. I thank her for the many facets of that case that she has articulated. Nonetheless, as the bioethicist most closely connected with the case at the clinical level I would like to take this opportunity to clarify, and (...) in some cases to correct, some facts.Dr Baylis entitles her section on the role of bioethics as “Stories of silence”. I differ from this view. Perhaps the stories are less stories of silence than stories to which others have not listened.I wish to make it quite clear that I have always supported Dr Olivieri and her colleagues in their actions with respect to the research that is at the centre of this case. I have been public in my support and I continue to be so.My departure from the Hospital for Sick Children was in no way caused by the Olivieri case. I was offered a challenging position at another Ontario …. (shrink)

Our memories are private and particular; when you and I share an experience our experience is yet in the very moment of sharing different for you and for me, and our two memories of an event in the past are still more disparate. For memories are shaped and constrained by the deep-lying organic stress of what we have lived through, of our actual living, in the interval between then and now. A memory follows the solitary track of our individual experience, (...) and, like the particle in modern Physical theory, is changed in and by the route it has traced. (shrink)

The experience of each one of us is individual, private and particular, and in its immediacy is incommunicable. Images of all sorts, sense factors, figments of the imagination, mental comments and judgments, all these impressions, some persistent, some fleeting, follow one another in endless passage through the consciousness.

In a paper on “Beauty and Greatness in Art” discussed at a recent meeting of the Aristotelian Society, Professor Alexander says: “In Art there are two standards; there is the strictly æsthetic standard, Is the work beautiful or not; has it attained beauty? and there is the question, Is it great or small?… This contrast of beauty and greatness is the old contrast of form and subject-matter.” Here is offered a problem of capital importance and of age-long interest, but alongside (...) of it there is a subsidiary and a much slighter question which has been comparatively little noticed and which may yet have bearing on the larger issue. This question is the relation of actual size, of size-in-itself, to the other factors in a work of art, and the reaction, if such there be, of such a size-factor upon the aesthetic whole. (shrink)

In this essay I present an overview of the problem of climate change, with attention to issues of interest to feminists, such as the differential responsibilities of nations and the disproportionate “vulnerabilities” of females, people of color, and the economically disadvantaged in relation to climate change. I agree with others that justice requires governments, corporations, and individuals to take full responsibility for histories of pollution, and for present and future greenhouse gas emissions. Nonetheless I worry that an overemphasis on household (...) and personal-sphere fossil fuel emissions distracts from attention to higher-level corporate and governmental responsibilities for addressing the problem of climate change. I argue that more attention should be placed on the higher-level responsibilities of corporations and governments, and I discuss how individuals might more effectively take responsibility for addressing global climate change, especially when corporations and governments refuse to do so.

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.

What is the nature of deep disagreement? In this paper, I consider two similar albeit seemingly rival answers to this question: the Wittgensteinian theory, according to which deep disagreements are disagreements over hinge propositions, and the fundamental epistemic principle theory, according to which deep disagreements are disagreements over fundamental epistemic principles. I assess these theories against a set of desiderata for a satisfactory theory of deep disagreement, and argue that while the fundamental epistemic principle theory does better than the Wittgensteinian (...) theory on this score, the fundamental epistemic principle theory nevertheless struggles to explain the variety of deep disagreement.

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)

This article argues for a revised best system account of laws of nature. David Lewis’s original BSA has two main elements. On the one hand, there is the Humean base, which is the totality of particular matters of fact that obtain in the history of the universe. On the other hand, there is what I call the ‘nomic formula’, which is a particular operation that gets applied to the Humean base in order to output the laws of nature. My revised (...) account focuses on this latter element of the view. Lewis conceives of the nomic formula as a balance of simplicity and strength, but I argue that this is a mistake. Instead, I motivate and develop a different proposal for the standards that figure into the nomic formula, and I suggest a rationale for why these should be the correct standards. Specifically, I argue that the nomic formula should be conceived as a collection of desiderata designed to generate principles that are predictively useful to creatures like us. The resulting view—which I call the ‘best predictive system’ account of laws—is thus able to explain why scientists are interested in discovering the laws, and it also gives rise to laws with the sorts of features that we find in actual scientific practice 1Introduction2The LOPP3A Problem with Lewis's Formula4A Pragmatic Account of the Nomic Formula 4.1Informative dynamics4.2Wide applicability4.3Spatial locality4.4Temporal locality4.5Spatial, temporal, and rotational symmetries4.6Predictively useful properties4.7Simplicity4.8Recap5 Conclusion.

This paper explores the application of hinge epistemology to deep disagreement. Hinge epistemology holds that there is a class of commitments—hinge commitments—which play a fundamental role in the structure of belief and rational evaluation: they are the most basic general ‘presuppositions’ of our world views which make it possible for us to evaluate certain beliefs or doubts as rational. Deep disagreements seem to crucially involve disagreements over such fundamental commitments. In this paper, I consider pessimism about deep disagreement, the thesis (...) that such disagreements are rationally irresolvable, and ask whether the Wittgensteinian account of deep disagreement—according to which such disagreements are disagreements over hinge commitments—provides adequate support for pessimism. I argue that the answer to this question depends on what hinge commitments are and what our epistemic relation to them is supposed to be. I argue for two core claims. First, that non-epistemic theories of hinge commitments provide adequate support for pessimism. Nevertheless, such theories have highly implausible consequences in the context of deep disagreement. Secondly, at least one epistemic theory of hinge commitments, the entitlement theory, permits optimism about such disagreements. As such, while hinge epistemology is mainly pessimistic about deep disagreement, it doesn’t have to be. (shrink)

Some disagreements concern our most fundamental beliefs, principles, values, or worldviews, such as those about the existence of God, society and politics, or the trustworthiness of science. These are ‘deep disagreements’. But what exactly are deep disagreements? This paper critically overviews theories of deep disagreement. It does three things. First, it explains the differences between deep and other kinds of disagreement, including peer, persistent, and widespread disagreement. Second, it critically overviews two mainstream theories of deep disagreement, the Wittgensteinian account and (...) the Fundamental Epistemic Principle account, before introducing a Hybrid account. Finally, it explores the notion that deep disagreements can be deeper than others. (shrink)

It has historically been assumed that comparative and superlative quantifiers can be semantically analysed in accordance with their core logical–mathematical properties. However, recent theoretical and experimental work has cast doubt on the validity of this assumption. Geurts & Nouwen have claimed that superlative quantifiers possess an additional modal component in their semantics that is absent from comparative quantifiers and that this accounts for the previously neglected differences in usage and interpretation between the two types of quantifier that they identify. Their (...) semantically modal hypothesis has received additional support from empirical investigations. In this article, we further corroborate that superlative quantifiers have additional modal interpretations. However, we propose an alternative analysis, whereby these quantifiers possess the semantics postulated by the classical model and the additional aspects of meaning arise as a consequence of psychological complexity and pragmatic implicature. We explain how this model is consistent with the existing empirical findings. Additionally, we present the findings of four novel experiments that support our model above the semantically modal account. (shrink)

The second edition of Doing Ethics in Media continues its mission of providing an accessible but comprehensive introduction to media ethics, with a theoretical grounding in moral philosophy, to help students think clearly and systematically about dilemmas in the rapidly changing media environment. Each chapter highlights specific considerations, cases, and practical applications for the fields of journalism, advertising, digital media, entertainment, public relations, and social media. Six fundamental decision-making questions - the "5Ws and H" around which the book is organized (...) - provide a path for students to articulate the issues; understand applicable law and ethics codes; consider the needs of stakeholders; work through conflicting values; integrate philosophic principles; and pose a "test of publicity." Students are challenged to be active ethical thinkers through the authors' reader-friendly style and use of critical early-career examples. While most people will change careers several times during their lives, all of us are life-long media consumers, and Doing Ethics in Media prepares readers for that task. Doing Ethics in Media is aimed at undergraduate and graduate students studying media ethics in mass media, journalism, and media studies. It also serves students in rhetoric, popular culture, communication studies, and interdisciplinary social sciences. The book's companion website-doingethicsin.media, or www.doingmediaethics.com-provides continuously updated real-world media ethics examples and collections of essays from experts and students. The site also hosts ancillary materials for students and for instructors, including a test bank and instructor's manual. (shrink)

It has been generally assumed that certain categories of numerical expressions, such as ‘more than n’, ‘at least n’, and ‘fewer than n’, systematically fail to give rise to scalar implicatures in unembedded declarative contexts. Various proposals have been developed to explain this perceived absence. In this paper, we consider the relevance of scale granularity to scalar implicature, and make two novel predictions: first, that scalar implicatures are in fact available from these numerical expressions at the appropriate granularity level, and (...) second, that these implicatures are attenuated if the numeral has been previously mentioned or is otherwise salient in the context. We present novel experimental data in support of both of these predictions, and discuss the implications of this for recent accounts of numerical quantifier usage. (shrink)

Conflicting accounts of the role of mathematics in our physical theories can be traced to two principles. Mathematics appears to be both (1) theoretically indispensable, as we have no acceptable non-mathematical versions of our theories, and (2) metaphysically dispensable, as mathematical entities, if they existed, would lack a relevant causal role in the physical world. I offer a new account of a role for mathematics in the physical sciences that emphasizes the epistemic benefits of having mathematics around when we do (...) science. This account successfully reconciles theoretical indispensability and metaphysical dispensability and has important consequences for both advocates and critics of indispensability arguments for platonism about mathematics.

What is the epistemological significance of deep disagreement? Part I explored the nature of deep disagreement, while Part II considers its epistemological significance. It focuses on two core problems: the incommensurability and the rational resolvability problems.

We then pivot to the (...) ethical and political dimensions of deep disagreement. We focus on whether an unwillingness to engage with positions one considers to be immoral or repugnant might be good, and conclude with some reflections on the moral risks of engagement. (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 chapter concludes with a brief discussion of issues to (...) do with fittingness that aren’t covered extensively by the volume’s chapters in order to indicate avenues for further research.

One of the main challenges confronting Humean accounts of natural law is that Humean laws appear to be unable to play the explanatory role of laws in scientific practice. The worry is roughly that if the laws are just regularities in the particular matters of fact (as the Humean would have it), then they cannot also explain the particular matters of fact, on pain of circularity. Loewer (2012) has defended Humeanism, arguing that this worry only arises if we fail to (...) distinguish between scientific and metaphysical explanations. However, Lange (2013, 2018) has argued that scientific and metaphysical explanations are linked by a transitivity principle, which would undercut Loewer's defense and re-ignite the circularity worry for the Humean. I argue here that the Humean has antecedent reasons to doubt that there are any systematic connections between scientific and metaphysical explanations. The reason is that the Humean should think that scientific and metaphysical explanation have disparate aims, and therefore that neither form of explanation is beholden to the other in its pronouncements about what explains what. Consequently, the Humean has every reason to doubt that Lange's transitivity principle obtains. (shrink)

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.

Can there be phenomenal consciousness without self-consciousness? Strong intuitions and prominent theories of consciousness say “no”: experience requires minimal self-awareness, or “subjectivity”. This “subjectivity principle” faces apparent counterexamples in the form of anomalous mental states claimed to lack self-consciousness entirely, such as “inserted thoughts” in schizophrenia and certain mental states in depersonalization disorder. However, Billon & Kriegel have defended SP by arguing that while some of these mental states may be totally selfless, those states are not phenomenally conscious and thus (...) do not constitute genuine counterexamples to SP. I argue that this defence cannot work in relation to certain experiences of ego dissolution induced by potent fast-acting serotonergic psychedelics. These mental states jointly instantiate the two features whose co-instantiation by a single mental state SP prohibits: phenomenal consciousness and total lack of self-consciousness. One possible objection is that these mental states may lack “me-ness” and “mineness” but cannot lack “for-me-ness”, a special inner awareness of mental states by the self. In response I propose a dilemma. For-me-ness can be defined either as containing a genuinely experiential component or as not. On the first horn, for-me-ness is clearly absent from my counterexamples. On the second horn, for-me-ness has been defined in a way that conflicts with the claims and methods of its proponents, and the claim that phenomenally conscious mental states can totally lack self-consciousness has been conceded. I conclude with some reflections on the intuitive plausibility of SP in light of evidence from altered states. (shrink)

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)

One recent development in epistemology, the philosophical study of knowledge, is the notion of ‘epistemic innocence’ introduced by Bortolotti and colleagues. This concept expresses the idea that certain suboptimal cognitive processes may nonetheless have epistemic (knowledge-related) benefits. The idea that delusion or confabulation may have psychological benefits is familiar enough. What is novel and interesting is the idea that such conditions may also yield significant and otherwise unavailable epistemic benefits. I apply the notion of epistemic innocence to research on the (...) transformative potential of psychedelic drugs. The popular epithet ‘hallucinogen’ exemplifies a view of these substances as fundamentally epistemically detrimental. I argue that the picture is more complicated and that some psychedelic states can be epistemically innocent. This conclusion is highly relevant to policy debates about psychedelic therapy. Moreover, analysing the case of psychedelics can shed further light on the concept of epistemic innocence itself. (shrink)

The moral enhancement of humans by biological or genetic means has recently been urged as a response to the pressing concerns facing human civilization. In this paper, I argue that proponents of biological moral enhancement have misrepresented the facts of human moral psychology. As a result, the likely effectiveness of traditional methods of moral enhancement has been underestimated, relative to biological or genetic means. I review arguments in favor of biological moral enhancement and argue that the complexity of moral psychology (...) raises serious problems for such interventions. I offer a programmatic sketch of the ways in which our improved understanding of moral psychology can help facilitate more traditional methods of moral enhancement. I conclude that the best response to the dangers faced by human civilization is the continued use of traditional methods of moral enhancement and the use of our improved understanding of moral psychology to further refine and develop these methods.

This article investigates the relationships between forms of humor that conjure up possible worlds and real-world social critiques. The first part of the article will argue that subversive humor, which is from or on behalf of historically and continually marginalized communities, constitutes a kind of aesthetic experience that can elicit enjoyment even in adversarial audiences. The second part will be a connecting piece, arguing that subversive humor can be constructed as brief narrative thought experiments that employ the use of fictionalized (...) scenarios to facilitate an open, playful attitude, encouraging a space for collaborative interpretation. This interaction between humorist and audience is an aesthetic experience that is enjoyable in and of itself, as the feelings of mirth are intrinsically valuable. But connected to the “Ha-ha!” experience of these sorts of humorous creations is an “Aha!” or potentially revelatory experience that is a mixture of cognitive comprehension and motivated (emotional) response. The third part of the article will attempt to go beyond the consciousness-raising element with an account of how such possible worlds created in the realm of imagination through subversive humor can bleed into the real world of flesh and blood people. Finally, an example of subversive humor will be analyzed. (shrink)

The “Slicing Problem” is a thought experiment that raises questions for substrate-neutral computational theories of consciousness, including those that specify a certain causal structure for the computation like Integrated Information Theory. The thought experiment uses water-based logic gates to construct a computer in a way that permits cleanly slicing each gate and connection in half, creating two identical computers each instantiating the same computation. The slicing can be reversed and repeated via an on/off switch, without changing the amount of matter (...) in the system. The question is what do different computational theories of consciousness believe is happening to the number and nature of individual conscious units as this switch is toggled. Under a token interpretation, there are now two discrete conscious entities; under a type interpretation, there may remain only one. Both interpretations lead to different implications depending on the adopted theoretical stance. Any route taken either allows mechanisms for “consciousness-multiplying exploits” or requires ambiguous boundaries between conscious entities, raising philosophical and ethical questions for theorists to consider. We discuss resolutions under different theories of consciousness for those unwilling to accept consciousness-multiplying exploits. In particular, we specify three features that may help promising physicalist theories to navigate such thought experiments. (shrink)

We review Potts’ influential book on the semantics of conventional implicature (CI), offering an explication of his technical apparatus and drawing out the proposal’s implications, focusing on the class of CIs he calls supplements. While we applaud many facets of this work, we argue that careful considerations of the pragmatics of CIs will be required in order to yield an empirically and explanatorily adequate account.

What should we do when faced with powerful theoretical arguments that support a severe change in our personal beliefs and commitments? For example, what should new parents do when confronted by unanswered anti-natalist arguments, or two lovers vexed by social theory that apparently undermines love? On the one hand, it would be irrational to ignore theory just because it’s theory; good theory is evidence, after all. On the other hand, factoring in theory can be objectifying, or risks unraveling one's life, (...) fracturing one's identity or social relations. Sometimes, then, following the evidence where it apparently leads would mean not merely changing what we think but who we are. Some might say that there’s something right about the thought that theory can bear on what we ought to believe, it’s just that when we work with full beliefs, only then do we seriously risk having to substantially alter our doxastic economy when pressed by exceptional theoretical arguments. When we work with partial beliefs, however, this risk is greatly diminished. Others will say that we can advocate or champion revisionary positions whilst rationally retaining our pre-theoretical personal convictions. Still others will argue that we should adopt a Moorean posture towards the revisionary arguments. I argue that each response is inadequate, and argue instead that we are permitted to bracket certain kinds of theoretical evidence against our beliefs because of the personal and ethical risks born out of giving them serious consideration. In turn, some of philosophy's doxastic influence is constrained by its attendant ethical risks: the personal enjoys a partial insulation from the theoretical. I close by addressing what this means for practicing philosophers. (shrink)

Much of my book Philosophy of Psychedelics is devoted to elaborating and defending two basic claims: that psychedelic therapy works mainly by changing mental representations of the self, and that it has many epistemic benefits consistent with a naturalistic worldview. The commentaries in this symposium generally focus on one or the other of these claims. On the mechanistic front, the commentaries by Hoffman and by Martin and Sterzer seek to supplement my account by drawing attention to factors it does not (...) emphasize. In this reply I agree with most of their claims, but propose some important qualifications. Meanwhile, the commentaries by Lyon and Farrenikova and by Colombo challenge some core commitments of my account. I agree with many of their claims, but defend some of these core commitments. On the epistemological front, Bortolotti and Murphy-Hollies endorse the overall shape of my account and make some productive connections to ideas concerning agency-first epistemology and self know-how. Caporuscio brings into play the idea of self-shaping, which connects to self know-how, but argues against certain core claims of my account. I endorse many of these claims about agency-first, self know-how, and self-shaping, but propose some important qualifications. Finally, Fink agrees that psychedelic experiences can have some epistemic benefits, but argues that these do not pertain to epistemic justification, and that the main benefit is increased understanding. I am sympathetic to Fink’s proposal about understanding, but criticize some of his arguments for the thesis of Psychedelic Justification Impossibilism. (shrink)

Epistemic rationality seems to permit a more steadfast response to disagreements over our fundamental convictions than it does for our ordinary beliefs. Why is this? This essay explores three answers to this question: web-of-belief conservatism, moral encroachment, and hinge theories, and argues that hinge theories do a better job than the alternatives at vindicating the intuition that there is a rationally permissible asymmetry in our responses to disagreements over ordinary beliefs and fundamental convictions. The essay also shows how hinge theorists (...) can explain the existence of moral hinge propositions, which enables them to account for the rational permissibility of being steadfast in response to disagreements over fundamental moral convictions.

In lieu of an abstract, here is a brief excerpt of the content:Ethics & the Environment 7.2 (2002) 1-11 [Access article in PDF] On Ecofeminist Philosophy Chris Cuomo In the heat of a historical moment when the interwoven nature of imperialism, ecological degradation, exploitation of workers, racism, and women's oppression is painfully obvious to many, ecofeminism appears to be gaining in popularity. As Karen Warren's book Ecofeminist Philosophy (2000) illustrates, a key insight of ecological feminism is captured by the (...) phrase "it's all connected." In more precise terms, ecofeminism stresses the depth to which human realities are embedded in ecological realities, and the fact that we are all composed of physical and conceptual connections and relationships. Ecofeminists also make strong normative claims about those connections, and they find present ecological and social relationships to be far more morally troubling than "we" modern thinkers tend to acknowledge.Karen Warren's work has been incredibly influential in the development of ecofeminism, especially as a philosophical perspective. In her 1987 essay "Feminism and Ecology: Making Connections," she argued for a basic ecofeminist position: that feminists ought to pay attention to environmental issues and ecological interdependencies, and that environmentalists ought to attend to the connections among ecological degradation, sexism, and other forms of social oppression. A wealth of ecofeminist poetry, fiction, and political writing had been published in the seventies and early eighties, before "Feminism and Ecology" appeared on the pages of [End Page 1] the journal Environmental Ethics. But Karen Warren was the among the first to use the tools of analytic philosophy to articulate and argue for ecofeminism as a philosophical position, ethical approach, and political movement.In fact, Mary Daly's Gyn/Ecology: The Metaethics of Radical Feminism (1978) was arguably the first work in contemporary academic philosophy to engage ecofeminism (my first acquaintance with ecofeminist theory was made through a special issue of the feminist magazine Heresies, on feminism and ecology). But Daly's emphasis was on the plight of females in patriarchal social environments. Karen Warren and Australian philosopher Val Plumwood brought full focus to the eco in ecofeminism, applying feminist philosophy (and especially feminist ethics) to our relations with the more than human world, and in turn articulating a broader theory of oppression and liberation. Their analytic approaches resulted in philosophy that synthesizes as it clarifies, taking seriously the value of nature, the history of philosophy, the power of culture, and the insights of good science.In Ecofeminist Philosophy Karen Warren presents ecofeminism as a general school of thought, though she also argues for a particular set of ecofeminist principles, values, methodologies, and practices. In terms of both her method and her conclusions, it is important to note that her emphasis on clearly articulated principles is by no means a defense of an absolutist or falsely universalizing ethic. Rather, Warren's ecofeminist philosophy emerges from her reading of a wide and diverse array of theoretical and political examples. Like Noël Sturgeon's Ecofeminist Natures: Race, Gender, Feminist Theory and Political Action (1997), which focuses on feminist ecological movements, Warren's project is to look for and describe the family resemblances among diverse examples of ecofeminism. This approach allows her to articulate epistemic, moral, and political positions that are pluralist, yet do not avoid making bold truth-claims. For example, Warren argues that "something is a feminist issue if an understanding of it helps one understand the oppression, subordination, or domination of women" (Warren 2000, 1).In a sense such a definition is wide open, taking various approaches and issues to be worthy of feminist attention. At the same time, it certainly does not allow just any perspective to count as feminist. Throughout Ecofeminist Philosophy, Warren defends multicultural ethics while clearly advocating specific transcultural values, such as justice and caring: [End Page 2] If we dare to care, if we dare to enter into community with others through an honest recognition of our commonalities and differences, we will be poised to create generally respectful, nonviolent, care-based, intentional communities where commonalities and differences are just that...

In lieu of an abstract, here is a brief excerpt of the content:Ethics & the Environment 7.2 (2002) 1-11 [Access article in PDF] On Ecofeminist Philosophy Chris Cuomo In the heat of a historical moment when the interwoven nature of imperialism, ecological degradation, exploitation of workers, racism, and women's oppression is painfully obvious to many, ecofeminism appears to be gaining in popularity. As Karen Warren's book Ecofeminist Philosophy (2000) illustrates, a key insight of ecological feminism is captured by the (...) phrase "it's all connected." In more precise terms, ecofeminism stresses the depth to which human realities are embedded in ecological realities, and the fact that we are all composed of physical and conceptual connections and relationships. Ecofeminists also make strong normative claims about those connections, and they find present ecological and social relationships to be far more morally troubling than "we" modern thinkers tend to acknowledge.Karen Warren's work has been incredibly influential in the development of ecofeminism, especially as a philosophical perspective. In her 1987 essay "Feminism and Ecology: Making Connections," she argued for a basic ecofeminist position: that feminists ought to pay attention to environmental issues and ecological interdependencies, and that environmentalists ought to attend to the connections among ecological degradation, sexism, and other forms of social oppression. A wealth of ecofeminist poetry, fiction, and political writing had been published in the seventies and early eighties, before "Feminism and Ecology" appeared on the pages of [End Page 1] the journal Environmental Ethics. But Karen Warren was the among the first to use the tools of analytic philosophy to articulate and argue for ecofeminism as a philosophical position, ethical approach, and political movement.In fact, Mary Daly's Gyn/Ecology: The Metaethics of Radical Feminism (1978) was arguably the first work in contemporary academic philosophy to engage ecofeminism (my first acquaintance with ecofeminist theory was made through a special issue of the feminist magazine Heresies, on feminism and ecology). But Daly's emphasis was on the plight of females in patriarchal social environments. Karen Warren and Australian philosopher Val Plumwood brought full focus to the eco in ecofeminism, applying feminist philosophy (and especially feminist ethics) to our relations with the more than human world, and in turn articulating a broader theory of oppression and liberation.

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. This book was the winner of the International Committee of Architectural Critics 2017 Bruno Zevi Book Award by unanimous decision of the international jury. (shrink)

A "good" arguer is like an architect with a penchant for civil and civic engineering. Such an arguer can design and present their reasons artfully about a variety of topics, as good architects do with a plenitude of structures and in various environments. Failures in this are rarely hidden for long, as poor constructions reveal themselves, often spectacularly, so collaboration among civical engineers can be seen as a virtue. Our logical virtues should be analogous. When our arguments fail due to (...) being uncivil and demagogic, since we inhabit the arguments we build, we are all crushed beneath our flawed reasoning. This mixed metaphor takes us to a self-referential analysis of argumentation, analogy, and humor. I argue that good argumentation strives to collaboratively convince rather than belligerently persuade. A convincing means toward this end is through humorous analogical arguments, whether the matter at hand is ethical, logical, theological, phenomenological, epistemological, metaphysical, political, or about baseball.
