Governments today often apologize for past injustices and scholars increasingly debate the issue, with many calling for apologies and reparations. Others suggest that what matters are victims of injustice today, not injustices in the past. Spinner-Halev argues that the problem facing some peoples is not just the injustice of the past, but that they still suffer from injustice today. They experience what he calls enduring injustices, and it is likely that these will persist without action to address them. The history (...) of these injustices matters, not as a way to assign responsibility or because we need to remember more, but in order to understand the nature of the injustice and to help us think of possible ways to overcome it. Suggesting that enduring injustices fall outside the framework of liberal theory, Spinner-Halev spells out the implications of arguments for conceptions of liberal justice and progress, reparations, apologies, state legitimacy and post-nationalism.

Benj’s paper is a characteristically thoughtful, imaginative, and wide-ranging exploration of the relationship between certain direct realist theories of perception and the nature of perceptual justification — with some formal semantics thrown in for good measure. Here I’ll focus on just one of the many topics about which Benj has something to say: his remarks on the topic of the relationship that must obtain between a perceptual state and a belief in order for the former to immediately justify the latter.

The nature of predication, and its relation to truth, is the central topic of Davidson’s posthumously published Truth and Predication . The main task which an account of predication should accomplish is a solution to the problem of predication; and that, Davidson tells us, is the problem of explaining what makes some collections of words, but not others, true or false (86). It is so-called because, Davidson thinks, the principal challenge faced by any answer to this problem is the problem (...) of explaining the distinctive contribution made by predicates to the truth or falsity of sentences. (shrink)

Davidson aimed to explain predication in terms of truth. I explain what is distinctive about his approach by contrasting it with the widely held view that predication and truth must both be explained in terms of the properties of propositions. I consider Davidson's arguments against this propositionalist alternative, and conclude by exploring some commonalities between Davidson's approach and the more recent propositionalist views of King and Soames.

In 2020, COVID-19, the Australia bushfires, and other global threats served as vivid reminders that human and nonhuman fates are increasingly linked. Human use of nonhuman animals contributes to pandemics, climate change, and other global threats which, in turn, contribute to biodiversity loss, ecosystem collapse, and nonhuman suffering. Jeff Sebo argues that humans have a moral responsibility to include animals in global health and environmental policy. In particular, we should reduce our use of animals as part of our pandemic (...) and climate change mitigation efforts and increase our support for animals as part of our adaptation efforts. Applying and extending frameworks such as One Health and the Green New Deal, Sebo calls for reducing support for factory farming, deforestation, and the wildlife trade; increasing support for humane, healthful, and sustainable alternatives; and considering human and nonhuman needs holistically. Sebo also considers connections with practical issues such as education, employment, social services, and infrastructure, as well as with theoretical issues such as well-being, moral status, political status, and population ethics. In all cases, he shows that these issues are both important and complex, and that we should neither underestimate our responsibilities because of our limitations, nor underestimate our limitations because of our responsibilities. Both an urgent call to action and a survey of what ethical and effective action requires, Saving Animals, Saving Ourselves is an invaluable resource for scholars, advocates, policy-makers, and anyone interested in what kind of world we should attempt to build and how.

We often evaluate belief-forming processes, agents, or entire belief states for reliability. This is normally done with the assumption that beliefs are all-or-nothing. How does such evaluation go when we’re considering beliefs that come in degrees? I consider a natural answer to this question that focuses on the degree of truth-possession had by a set of beliefs. I argue that this natural proposal is inadequate, but for an interesting reason. When we are dealing with all-or-nothing belief, high reliability leads to (...) high levels of truth-possession. However, when it comes to degrees of belief, reliability and truth-possession part ways. The natural answer thus fails to be a good way to evaluate degrees of belief for reliability. I propose and develop an alternative method based on the notion of calibration, suggested by Frank Ramsey, which does not have this problem and consider why we should care about such assessments of reliability even if they are not tied directly to truth-possession.

What effect does creativity have on individuals, groups and societies, and on the fundamental values on which they base their actions and institutions? What constitutes good and evil, right and wrong, and how does creativity disrupt these beliefs? The Ethics of Creativity brings together an impressive collaboration of thinkers from several countries and disciplines to illuminate the thorny issues that arise when novel ideas and products brought forth by creativity collide with the rules and norms of what we believe to (...) be 'right' or 'good'. This book tackles questions of why most people claim to love creativity yet, in practice, may quash creative intentions, how creative innovations can create new ethical problems, when creativity and ethics tend to coincide and when they tend to conflict, and how both creativity and ethics might be harnessed to support a brighter future for all.

I argue that Husserlian phenomenology is metaphysically neutral, in the sense of being compatible with multiple metaphysical frameworks. For example, though Husserl dismisses the concept of an unknowable thing in itself as “material nonsense”, I argue that the concept is coherent and that the existence of such things is compatible with Husserl’s phenomenology. I defend this metaphysical neutrality approach against a number of objections and consider some of its implications for Husserl interpretation.

This book provides an original and provocative combination of ethnomethodological analysis and the concepts of linguistic philosophy with a breadth and clarity unusual in this field of writing. It is designed to be read by sociologists, psychologists and philosophers and concerns itself with the contributions of Wittgenstein, defending the claim for his relevance to the human sciences. However, this book goes some way beyond the usual limitations of such interdisciplinary works by outlining some empirical applications of ideas derived from the (...) Wittgenstein tradition.

Mitochondrial bioenergetics plays a key role in multiple basic cellular processes, such as energy production, nucleotide biosynthesis, and iron metabolism. It is an essential system for animals' life and death (apoptosis) and it is required for embryo development. This, in conjunction with its being subjected to adaptive processes in multiple species and its gene products being involved in the formation of reproductive barriers in animals, raises the possibility that mitochondrial bioenergetics could be a candidate genetic mechanism of speciation. Here, we (...) discuss genetic and biochemical evidence for the possible involvement of this unique system, encoded by two genomes (the mitochondrial and nuclear genomes), that differ by an order of magnitude in their mutation rates in processes leading to speciation events.

This article offers an alternative reading of the Abbé Sieyès and the modern ‘nation-state’ problématique. I argue that the subject/object that is constituted in the early days of modernity is the incomplete society: an impossible-possibility ideal of congruency of population, authority and space. I suggest reading this ideal of congruency as a fantasy in that it offers a certain ‘fullness to come’, the promise of jouissance that can never be attained and is thus constantly re-envisioned and reinvoked. Drawing on discourse-analytical (...) and psychoanalytical tools I explain the logic of fantasy before analysing Sieyès’ What is the Third Estate?, as I show how he critiques and fragments the old model of the state and how his reading of the nation is fantasmatic, a continuous project towards impossible congruency.

Aron Gurwitsch’s theory of the structure and dynamics of consciousness has much to offer contemporary theorizing about consciousness and its basis in the embodied brain. On Gurwitsch’s account, as we develop it, the field of consciousness has a variable sized focus or "theme" of attention surrounded by a structured periphery of inattentional contents. As the field evolves, its contents change their status, sometimes smoothly, sometimes abruptly. Inner thoughts, a sense of one’s body, and the physical environment are dominant field contents. (...) These ideas can be linked with (and help unify) contemporary theories about the neural correlates of consciousness, inattention, the small world structure of the brain, meta-stable dynamics, embodied cognition, and predictive coding in the brain.

The question whether cognition is subserved by internal processes in the brain (internalism) or extends in to the world (active externalism) has been vigorously debated in recent years. I show how internalist and externalist ideas can be pursued in a common framework, using (1) open dynamical systems, which allow for separate analysis of an agent's intrinsic and embodied dynamics, and (2) supervenience functions, which can be used to study how low-level dynamical systems give rise to higher-level dynamical structures.

According to our traditional conception of agency, most human beings are agents and most, if not all, nonhuman animals are not. However, recent developments in philosophy and psychology have made it clear that we need more than one conception of agency, since human and nonhuman animals are capable of thinking and acting in more than one kind of way. In this paper, I make a distinction between perceptual and propositional agency, and I argue that many nonhuman animals are perceptual agents (...) and that many human beings are both kinds of agent. I then argue that, insofar as human and nonhuman animals exercise the same kind of agency, they have the same kind of moral status, and I explore some of the moral implications of this idea.

This paper argues against two prominent accounts of what it is to "promote a desire," found in the work of Stephen Finlay and Mark Schroeder.

Consider the multi-user virtual worlds of online games such as EVE and World of Warcraft, or the multi-user virtual world of Second Life. Suppose a player performs an action in one of these worlds, via his or her virtual character, which would be wrong, if the virtual world were real. What is the moral status of this virtual action? In this paper I consider arguments for and against the Asymmetry Thesis: the thesis that such virtual actions are never wrong. I (...) also explain how the truth of the Asymmetry Thesis is closely aligned with the possibility of what Edward Castronova has called closed synthetic worlds. With some qualifications, the ultimate conclusion is that the Asymmetry Thesis is false and that these closed worlds are impossible. (shrink)

Theories of the structure of affect make competing predictions about whether people can feel happy and sad at the same time. Considerable evidence that happiness and sadness can co-occur has accumulated in the past 15 years, but holes in the case remain. I describe those holes and suggest strategies for testing them in future research. I also explore the possibility that the case may never be closed, in part because the competing hypotheses may not be entirely falsifiable. Fortunately, hypotheses need (...) not be falsifiable to be useful. Research on mixed emotions has been generative and the body of research will continue to shed light on the structure of affect.

In this article I wish to re-examine the vexed issue of the possibility of idealism in ancient and medieval philosophy with particular reference to the case of Johannes Scottus Eriugena (c. 800idealisms immaterialism as his standard for idealism, and it is this decision, coupled with his failure to acknowledge the legacy of German idealism, which prevents him from seeing the classical and medieval roots of idealism more broadly understood.

In this paper I discuss Edmund Husserl’s phenomenological account of the constitution of the social world, in relation to some phenomenological contributions to the constitution of sociality found in Husserl’s students and followers, including Heidegger, Gurwitsch, Walther, Otaka, and Schutz. Heidegger is often seen as being the first to highlight explicitly human existence as Mitsein and In-der-Welt-Sein, but it is now clear from the Husserliana publications that, in his private research manuscripts especially during his Freiburg years, Husserl employs many of (...) the terms associated with Heidegger, e.g. Mitwelt, Weltlichkeit, Alltäglichkeit, Zeitlichkeit, and Geschichtlichkeit, and had detailed discussions of various forms of social constitution. It is clear that Husserl and Heidegger were exploring these themes in dialogue with one another, and that Husserl, in fact, has a rich phenomenology of sociality that is worth exploring in its own right. In this paper, I will outline some of the key aspects of Husserl’s contribution. (shrink)

In this paper I ask how we should treat other beings in cases of uncertainty about sentience. I evaluate three options: an incautionary principle that permits us to treat other beings as non-sentient, a precautionary principle that requires us to treat other beings as sentient, and an expected value principle that requires us to multiply our subjective probability that other beings are sentient by the amount of moral value they would have if they were. I then draw three conclusions. First, (...) the precautionary and expected value principles are more plausible than the incautionary principle. Second, if we accept a precautionary or expected value principle, then we morally ought to treat many beings as having at least partial moral status. Third, if we morally ought to treat many beings as having at least partial moral status, then morality involves more cluelessness and demandingness than we might have thought. (shrink)

This paper aims to contribute to epistemology by studying the psychoanalytic notion of transference. Contrary to previous philosophical research on Freud, I claim that traditional models of interpretation or translation are insufficient to explain psychoanalytic understanding. After exploring the conceptual roots of this mistake, which I define as generic, I focus on the notion of transference and claim that it should be viewed as a unique form of understanding that enables the emergence of unconscious meaning or truth. I elaborate this (...) claim with a detailed study of the development of this notion in Freud’s texts. Transference is thus delineated as a form of understanding which is closely related to the matrix of love and defined in relation to the following parameters: intersubjectivity; visuality; and performativity.

Promotion is the relation between an act and a desire that obtains when the act advances or serves the desire. Under what conditions does an act promote a desire? Probabilistic accounts of promotion, the most prominent accounts, analyze promotion in terms of an increase in the probability of the desire’s satisfaction. In this paper, we clarify the promotion relation and explain why probabilistic accounts are attractive. Then we identify two questions probabilistic accounts must answer: the Baseline Question and the Interpretation (...) Question. We discuss and reject the three answers to the Baseline Question found in the literature, and explain the challenge future attempts at answering this question will face. Proponents of probabilistic accounts have not adequately addressed the Interpretation Question. We survey three answers to this question, finding each unsatisfactory. We conclude that no satisfactory probabilistic account has yet been offered, and that there are significant hurdles to providing one in the future. (shrink)

In this article, I articulate and respond to an epistemological challenge to meta-normative realism. The challenge has it that, if realism about the normative is correct, and if evolutionary forces have significantly influenced our normative judgments, then it would be a remarkable coincidence if the content of the normative facts and our normative judgments were aligned. I criticize David Enoch's recent attempt to meet this challenge, but provide an alternative response that is structurally similar. I argue that if realism is (...) correct, then it would be remarkable if the content of our normative judgments and the normative facts were not significantly aligned. (shrink)

This article provides empirical results indicating that acting in a socially respon- sible and lawful manner is a necessary, though not sufficient, condition for increasing shareholder wealth. It meta-analyzes 27 event studies that have mea- sured the stock market's reaction to incidences of socially irresponsible and illicit behavior. It finds that for firms engaging in socially irresponsible and illicit behavior, the effect on shareholder wealth is negative (wealth decreases), statisti- cally significant (p <.001), and so substantial in size (D = (...) -.932) that the distribution of abnormal returns is shifted nearly a full standard deviation to the left (i.e., negatively) from their expected standard normal distribution. This result gives rationally self-interested firms a self-interested reason to act in a socially responsible and law-abiding manner. It also provides support for a moral position called enlightened self-interest, which prescribes that firms should act in a socially responsible manner to promote the shareholders' interests.

This paper proposes that, in many cases, conversational norms permit gaslighting when socially subordinate speakers report systemic injustice. Section 1 introduces gaslighting and the kinds of cases on which I focus—namely, cases in which multiple people gaslight. I give examples and statistics to suggest that these cases are common in response to reports of race- or gender-based injustice; and I appeal to scholarship on epistemologies of ignorance to suggest that this kind of gaslighting is common because it is systematically produced (...) by dominant epistemic systems. Section 2 draws on Lynne Tirrell’s account of language games that’ve been influenced by oppression to make the case that conversational norms make gaslighting “appropriate” when socially subordinate speakers report systemic injustice. Together, these points make the case that the kind of gaslighting discussed in this paper (i) occurs systematically and (ii) is mutually reinforcing with systems of ignorance. The discussion is meant to help us understand and address the conditions that make gaslighting commonplace. If it’s true that gaslighting occurs systematically in part thanks to our warped conversational norms, then we may be able to mitigate the prevalence of gaslighting by attending to these norms.

Presumably, it also wants to exhibit contemporary Australian writing in the phenomenological tradition, and situate phenomenological claims in terms graspable by analytic philosophers.Robin Small's introduction, taking Husserl's conception of eidetic intuition as fundamental, sketches the rise of phenomenology. The collection is then divided into three parts. Part One ("Approaching the Sources") focuses on the sources of phenomenology (Husserl and Heidegger) and opens with a thoughtful essay by Max Deutscher, reprinted from the Canadian Journal of Philosophy (1980), which is replied to by Maurita Harney. Three further, not particularly distinguished, essays deal with the issues of realism, relativism, [End Page 422] and the relation between Ryle and Husserl. Part Two ("Following the Tradition") deals with new themes arising in Heidegger, Sartre, and Derrida, while Part Three ("Making Connections") explores the relation between phenomenology and other disciplines, chiefly sociology, anthropology, and literature. A final essay by Jocelyn Dunphy Bloomfield examines the relevance of phenomenology in the Australian context.The collection is interesting but uneven. Some of the essays are out of date: Small's essay on Ryle and Husserl originally appeared in 1981 and Purushottama Bilimoria's paper, "Heidegger and the Japanese Connection," first published in the Journal of the British Society for Phenomenology (1991), is in need of updating given the upsurge of interest in Husserl in Asia in recent years. Deutscher's "Husserl's Transcendental Subjectivity" is helpful in that it introduces Husserl's transcendental idealism through unusually prosaic analogies. He suggests that the transcendental attitude can be grasped in familiar experiences such as "keeping silence" during an awkward or embarrassing moment or adopting a detached or removed stance. An actor on stage can express anger without being angry. The transcendental attitude is such a detached spectator attitude; it is the capacity we have to judge and appraise ourselves (8). Moreover, it is in this attitude that we come to recognize our commitments to others. Deutscher resists the temptation to separate radically the ordinary living in the world from the detached contemplation of it. There never can be total but only intermittent detachment from the life-world; nevertheless the transcendental epoché is important in that it allows us the chance to gain self-awareness about our situation, about our "forms of life." While Deutscher does a terrific job demystifying one of Husserl's central and much misunderstood concepts, he is at risk of oversimplifying and worse of psychologizing Husserl's insights.Richard Campbell's essay on Heidegger's conception of truth as aletheia is also particularly noteworthy in that it is a philosophically sophisticated attempt to cut through Heidegger's somewhat inflated jargon and expresses his central intuitions about truth. Campbell goes to some trouble to elucidate and disambiguate what Heidegger is saying. Furthermore, he believes Heidegger is wrong in his interpretation of Plato; Plato is doing precisely the opposite of what Heidegger says he is doing. Deutscher's essay on Sartre, informed by an analytic rigor and sensitivity to ambiguity, gives a very clear account and partial defence of the relations between positional consciousness of the object and non-positional self-consciounsess. He is critical of Sartre's sweeping concept of the "in itself" and points out that in reality there are many diverse "in-itselves" with different real properties. Crittenden, too, has an interesting essay on Sartre's conception of "the look." Sartre understands the other as the one who looks at (and thereby seeks to objectify me) whereas for de Beauvoir, the other (in the particular case: woman) is the looked at and objectified.

Source Hybridism about practical reasons is the position that facts that constitute reasons sometimes derive their normative force from external metaphysical grounds, and sometimes from internal. Although historically less popular than either Source Internalism or Source Externalism, hybridism has lately begun to garner more attention. Here, I further the hybridist's cause by defending Source Hybridism from three objections. I argue that we are not warranted in rejecting hybridism for any of the following reasons: that hybridists cannot provide an account of (...) normative weight, that hybridists are committed to implausible results concerning practical deliberation, or that Source Hybridism is objectionably unparsimonious.

Focusing on Plato, Descartes, Kant, Kierkegaard, Nietzsche and Wittgenstein, this book uncovers philosophical rhetoric at work and reminds us of the rhetorical arena in which philosophical writings are produced (...) and considered.

A range of arguments are presented to demonstrate that (1) human visual orientations are conceptually constituted (concept?bound); (2) the concept?boundedness of visual orientations does not require a cognitivist account according to which a mental process of ?inference? or of ?interpretation? must be postulated to accompany a purely ?optical? registration of ?wavelengths of light?, ?photons?, or contentless ?information'; (3) concept?bound visual orientations are not all instances of ?seeing as?, contrary to some currently prominent cognitivist accounts; (4) the dispute between cognitivist and (...) realist accounts about the phenomenon of ?seeing as? is spurious, and is based upon a confusion about the fundamental analytical distinction made by Wittgenstein between ?seeing? and ?seeing as'; (5) ?perceiving?, ?seeing?, and ?seeing as? are but three of a large array of verbs of human visual orientation, and are not ?master categories? under which one can subsume these other modalities; (6) one cannot deduce a continuity of human visual orientation from a continuity of photon?photoreceptor interaction, a point we characterize as the ?staggered character? of human visual orientations; (7) detailed attention to the grammars of the diverse verbs of human visual orientation can open up a domain of study which we here refer to as a ?praxiology of perception'; (8) the nature of such an inquiry can be illustrated with exemplary reference to the analysis of the properties of ?noticing? as embedded in courses of practical action; and (9) such arguments, which claim that existing perceptual theories overly homogenize what is involved in visual orientations to the world, parallel those of Stroll, who proposes that standard accounts of ?what is perceived? overly homogenize the perceptible environment.

The Cuban government has undertaken the task of transforming insect pest and weed management from conventional to organic and more sustainable approaches on a nationwide basis. This paper addresses past programs and current major areas of research and implementation as well as provides examples of programs in insect and weed management. Topics covered include the newly constructed network of Centers for the Reproduction of Entomophages and Entomopathogens (CREEs), which provide the infrastructure for the implementation of biological control on state, cooperative, (...) and private farm operations. CREE programs include the mass rearing and release of Trichogramma spp. to manage insect pests of cassava, tobacco, sugarcane, and improved pasture. The entomopathogens, Bacillus thuringiensis, Beauveria bassiana, Metarhizium anisopliae, and Verticillium lecanii, are being mass produced in the CREEs and applied to control a number of key insect pests. A traditional method employed by peasant farmers of using the predatory ant Pheidole megacephala (Fabricius) in the biological control of sweetpotato and banana insect pests has been further developed and implemented. Efforts are underway to rear nematode species that attack insect pests and identify plant extracts with insecticidal qualities as potential management tools. Weed management has moved away from dependence on herbicides and toward alternative techniques that include weed suppression based on rotation schemes, limited use of selective herbicides, and new tillage equipment and practices.

Although debate is a richly structured and prevalent form of discourse, it has received little scholarly attention. Logicians have focused on the structure of individual arguments—how they divide into premises and conclusions, which in turn divide into various constituents. In contrast, I focus on the structure of sets of arguments, showing how arguments are themselves constituents in high-level dialectical structures. I represent debates and positions by graphs whose vertices correspond to arguments and whose edges correspond to two inter-argument relations: “dispute” (...) and “support,” respectively. On this basis I develop a theory of the structure of debate. (shrink)
