Some types of solar radiation management (SRM) research are ethically problematic because they expose persons, animals, and ecosystems to significant risks. In our earlier work, we argued for ethical norms for SRM research based on norms for biomedical research. Biomedical researchers may not conduct research on persons without their consent, but universal consent is impractical for SRM research. We argue that instead of requiring universal consent, ethical norms for SRM research require only political legitimacy in decision-making about global SRM trials. (...) Using Allen Buchanan & Robert Keohane's model of global political legitimacy, we examine several existing global institutions as possible analogues for a politically legitimate SRM decision-making body.

This collection of articles was written over the last 10 years and the most important and longest within the last year. Also I have edited them to bring them up to date (2016). All the articles are about human behavior (as are all articles by anyone about anything), and so about the limitations of having a recent monkey ancestry (8 million years or much less depending on viewpoint) and manifest words and deeds within the framework of our innate psychology as (...) presented in the table of intentionality. As famous evolutionist Richard Leakey says, it is critical to keep in mind not that we evolved from apes, but that in every important way, we are apes. If everyone was given a real understanding of this (i.e., human ecology and psychology) in school, maybe civilization would have a chance. In my view these articles and reviews have many novel and highly useful elements, in that they use my own version of the recently (ca. 1980’s) developed dual systems view of our brain and behavior to lay out a logical system of rationality (personality, psychology, mind, language, behavior, thought, reasoning, reality etc.) that is sorely lacking in the behavioral sciences (psychology, philosophy, literature, politics, anthropology, history, economics, sociology etc.).

The first group of articles attempt to give some insight into how we behave that is reasonably free of theoretical delusions. In the next three groups I comment on three of the principal delusions preventing a sustainable world— technology, religion and politics (cooperative groups). People believe that society can be saved by them, so I provide some suggestions in the rest of the book as to why this is unlikely via short articles and reviews of recent books by well-known writers. (...) -/- America and the world are in the process of collapse from excessive population growth, most of it for the last century and now all of it due to 3rd world people. Consumption of resources and the addition of 4 billion more ca. 2100 will collapse industrial civilization and bring about starvation, disease, violence and war on a staggering scale. Billions will die and nuclear war is all but certain. In America this is being hugely accelerated by massive immigration and immigrant reproduction, combined with abuses made possible by democracy. Depraved human nature inexorably turns the dream of democracy and diversity into a nightmare of crime and poverty. The root cause of collapse is the inability of our innate psychology to adapt to the modern world, which leads people to treat unrelated persons as though they had common interests. This, plus ignorance of basic biology and psychology, leads to the social engineering delusions of the partially educated who control democratic societies. Few understand that if you help one person you harm someone else—there is no free lunch and every single item anyone consumes destroys the earth beyond repair. Consequently social policies everywhere are unsustainable and one by one all societies without stringent controls on selfishness will collapse into anarchy or dictatorship. Without dramatic and immediate changes, there is no hope for preventing the collapse of America, or any country that follows a democratic system. Hence my concluding essay “Suicide by Democracy”. -/- Those wishing to read my other writings may see Talking Monkeys 2nd ed (2019), The Logical Structure of Philosophy, Psychology, Mind and Language in Ludwig Wittgenstein and John Searle 2nd ed (2019), Suicide by Democracy 3rd ed (2019), The Logical Stucture of Human Behavior (2019) and Suicidal Utopian Delusions in the 21st Century 4th ed (2019) .

This collection of articles and reviews are about human behavior (as are all articles by anyone about anything), and so about the limitations of having a recent monkey ancestry (8 million years or much less depending on viewpoint) and manifest words and deeds within the framework of our innate psychology as presented in the table of intentionality. As famous evolutionist Richard Leakey says, it is critical to keep in mind not that we evolved from apes, but that in every important (...) way, we are apes. If everyone was given a real understanding of this (i.e., of human ecology and psychology to actually give them some control over themselves), maybe civilization would have a chance. As things are however the leaders of society have no more grasp of things than their constituents and so collapse into anarchy and dictatorship appears inevitable. -/- Since philosophy proper is essentially the same as the descriptive psychology of higher order thought (behavior), and philosophical problems are the result of our innate psychology, or as Wittgenstein put it, due to the lack of perspicuity of language, they run throughout human discourse and behavior, so there is endless need for philosophical analysis, not only in the ‘human sciences’ of philosophy, sociology, anthropology, political science, psychology, history, literature, religion, etc., but in the ‘hard sciences’ of physics, mathematics, and biology. It is universal to mix the language game questions with the real scientific ones as to what the empirical facts are. Scientism is ever present and the master has laid it before us long ago, i.e., Wittgenstein (hereafter W) beginning with the Blue and Brown Books in the early 1930’s. -/- Although I separate the book into sections on philosophy and psychology, religion, biology, the ‘hard sciences’ and politics/sociology/economics, all the articles, like all behavior, are intimately connected if one knows how to look at them. As I note, The Phenomenological Illusion (oblivion to our automated System 1) is universal and extends not merely throughout philosophy but throughout life. I am sure that Chomsky, Obama, Zuckerberg and the Pope would be incredulous if told that they suffer from the same problems as Hegel, Husserl and Heidegger, or that that they differ only in degree from drug and sex addicts in being motivated by stimulation of their frontal cortices by the delivery of dopamine (and over 100 other chemicals) via the ventral tegmentum and the nucleus accumbens, but it’s clearly true. While the phenomenologists only wasted a lot of people’s time, they are wasting the earth and their descendant’s future. -/- I hope that these essays will help to separate the philosophical issues of language use from the scientific factual issues, and in some small way hinder the collapse of civilization, or at least make it clear why it is doomed. -/- Those wishing to read my other writings may see Talking Monkeys 2nd ed (2019), The Logical Structure of Philosophy, Psychology, Mind and Language in Ludwig Wittgenstein and John Searle 2nd ed (2019), Suicide by Democracy 3rd ed (2019), The Logical Stucture of Human Behavior (2019) and Suicidal Utopian Delusions in the 21st Century 4th ed (2019) .

In this paper, the authors show that there is a reading of St. Anselm's ontological argument in Proslogium II that is logically valid (the premises entail the conclusion). This reading takes Anselm's use of the definite description "that than which nothing greater can be conceived" seriously. Consider a first-order language and logic in which definite descriptions are genuine terms, and in which the quantified sentence "there is an x such that..." does not imply "x exists". Then, using an ordinary logic (...) of descriptions and a connected greater-than relation, God's existence logically follows from the claims: (a) there is a conceivable thing than which nothing greater is conceivable, and (b) if <em>x</em> doesn't exist, something greater than x can be conceived. To deny the conclusion, one must deny one of the premises. However, the argument involves no modal inferences and, interestingly, Descartes' ontological argument can be derived from it. (shrink)

Although he died in 2008, prolific science novelist Michael Crichton – acting as a ‘ghost-writer’, so to speak – continues to add new titles to his oeuvre. Notwithstanding the death of the author, his novel-producing machinery refuses to come to a full stop, - although in this case Richard Preston (a science novelist in his own right, author of, among others, The Hot Zone, on viral infections) was recruited to finish the book. MICRO – a title that almost reads (...) like the acronym of the author’s name - has all the ingredients of the standard Michael Crichton formula. (shrink)

This paper concerns the relationship between two questions. The first is a question about inner freedom: What is it to be rendered unfree, not by external obstacles, but by aspects of oneself? The second is a question about agency: What is it to fail at being a thing that genuinely acts, and instead to be a thing that is merely acted upon, passive in relation to its own behaviour? It is widely believed that answers to the first question must rest (...) on or be partly explained by answers to the second. Here I argue that this is a mistake: losses of inner freedom are not, after all, explicable in terms of failures of agency. To establish this conclusion, I consider three familiar lines of thought that appear to tie ideas about inner freedom to ideas about agency, each relating to a different conception of inner freedom: absence of inner constraint, self-government, and absence of determination by external forces. I argue that, in each case, any apparent conceptual reliance on a special conception of agency is merely illusory, the result being that we must allow clear water between our theories of inner freedom and our theories of agency. This conclusion is of significance for contemporary theories of agency and personal autonomy, as well as for ‘positive’ conceptions of political liberty. (shrink)

Our computational metaphysics group describes its use of automated reasoning tools to study Leibniz’s theory of concepts. We start with a reconstruction of Leibniz’s theory within the theory of abstract objects (henceforth ‘object theory’). Leibniz’s theory of concepts, under this reconstruction, has a non-modal algebra of concepts, a concept-containment theory of truth, and a modal metaphysics of complete individual concepts. We show how the object-theoretic reconstruction of these components of Leibniz’s theory can be represented for investigation by means of automated (...) theorem provers and finite model builders. The fundamental theorem of Leibniz’s theory is derived using these tools. (shrink)

Michael Crichton‟s latest novel Next (2006) is his third about genomics. Yet, whereas Jurassic Park (and its sequel The lost world) contained stories about sequencing, reconstructing and revivifying the genomes of (extinct) animals, Next analyses the impact of genomics in the biomedical sphere: its consequences for human life (health, labour, sexuality, family life). Gene patenting, and the philosophy of genetic determinism that inspired and legitimised this practice, is at the root of most of the soap-like absurdities Crichton stages in (...) his novel.

It is argued that a subject who has an experience as of succession can have this experience at a time, or over a period of time, during which there occurs in him no succession of conscious mental states at all. Various metaphysical implications of this conclusion are explored. One premise of the main argument is that every experience is an experience as of succession. This implies that we cannot understand phenomenal temporality as a relation among experiences, but only as a (...) primitive feature of experience, or else as something analyzable into wholly non-phenomenal terms.

In this article I argue that Hutcheson has a theory of obligation that is different in important ways from the views of his predecessors and that his theory may not be as problematic as critics have claimed. In section (I) I sketch a brief picture of the rich conceptual landscape surrounding the concept of obligation in the Early Modern period. I focus on the five figures Hutcheson explicitly references: Hugo Grotius, Samuel Pufendorf, their French translator and commentator Jean Barbeyrac, as (...) well as G. W. Leibniz and Richard Cumberland. In section (II) I offer an account of Hutcheson’s theory of obligation and illustrate that not only does Hutcheson have a view on what previous figures called the source, end, and object of obligation, he also focuses on the epistemological question of the origin of our idea of obligation as opposed to the metaphysical question of the efficient cause of obligation. Furthermore, although Hutcheson shares with his predecessors the idea that obligation implies a certain kind of necessity, he conceives of this necessity in a unique way, namely in terms of the necessity of a perception. In section (III) I defend Hutcheson’s theory of obligation against three objections: 1. that it makes a sham of obligation by locating its source within the human being, 2. that it is reducible to divine command theory, and 3. that, in the end, Hutcheson has no real or meaningful theory of obligation. My hope is that, at the very least, appraising these objections helps further clarify the theory of obligation that Hutcheson presents in his works. (shrink)

According to panpsychists, physical phenomena are, at bottom, nothing but experiential phenomena. One argument for this view proceeds from an alleged need for physical phenomena to have features beyond what physics attributes to them; another starts by arguing that consciousness is ubiquitous, and proposes an identification of physical and experiential phenomena as the best explanation of this alleged fact. The first argument assumes that physical phenomena have categorical natures, and the second that the world’s experience-causing powers or potentials underdetermine its (...) physical features. I argue that panpsychists are not entitled to these assumptions. (shrink)

It is generally assumed that if it is possible to believe that p without believing that q, then there is some difference between the object of the thought that p and the object of the thought that q. This assumption is challenged in the present paper, opening the way to an account of epistemic opacity that improves on existing accounts, not least because it casts doubt on various arguments that attempt to derive startling ontological conclusions from seemingly innocent epistemic premises.

Someone who knew everything about the world’s physical nature could, apparently, suffer from ignorance about various aspects of conscious experience. Someone who knew everything about the world’s physical and mental nature could, apparently, suffer from moral ignorance. Does it follow that there are ways the world is, over and above the way it is physically or psychophysically? This paper defends a negative answer, based on a distinction between knowing the fact that p and knowing that p. This distinction is made (...) intelligible by reference to criterial connections between the possession of moral or phenomenal knowledge, and the satisfaction of cognitively neutral conditions of desire and experiential history. The existence of such connections in the moral case makes for an efficient dissolution of the so-called moral problem. (shrink)

Humans often behave altruistically towards strangers with no chance of reciprocation. From an evolutionary perspective, this is puzzling. The evolution of altruistic cooperative behavior—in which an organism’s action reduces its fitness and increases the fitness of another organism —only makes sense when it is directed at genetically related organisms or when one can expect the favor to be returned. Therefore, evolutionary theorists such as Sober and Wilson have argued that we should revise Neo-Darwininian evolutionary theory. They argue that human altruism (...) evolved through group selection in which groups of altruists were naturally selected because they had a comparative advantage over other groups. Wilson and Sober’s hypothesis attracted followers but is rejected by most of their peers. The heated debate between advocates and critics of group selection often suffers from a lack of conceptual clarity. In response, I set out to clearly distinguish ‘genetic’ from ‘cultural’ group selection and argue that the latter does not face the potentially debilitating problems plaguing the former. I defend the claim that human altruistic dispositions evolved through cultural group selection and gene-culture coevolution and offer empirical evidence in support. I also argue that actual altruistic behavior often goes beyond the kind of behavior humans have evolved to display. Conscious and voluntary reasoning processes, I show, have an important role in altruistic behavior. This is often overlooked in the scientific literature on human altruism. (shrink)

[GER] Michael Lewin geht es in seinem Buch nicht nur um philosophiehistorische Perspektiven der Kant- und Fichte-Forschung, sondern ebenso sehr um die Sache selbst: das Konzept der Vernunft im engeren Sinne als ein potenziell wohlbegründetes und in zeitgenössischen Kontexten fortführbares Forschungsprogramm. Dabei sind verschiedene, in einer Reihe der Reflexion stehende Theoriegefüge bewusst zu machen, die sich aus den vielfältigen Arten und Funktionen der Ideen ergeben, mit deren Hilfe die Vernunft das Verstehen und Wollen steuert und selbstreflexiv wird. Nach der (...) Untersuchung von sieben Ideenarten bei Kant und ihrer von der Tathandlung (der Selbstsetzung der reinen Vernunft) ausgehenden Systematisierung bei Fichte wird die Frage erörtert, ob, wie und unter welchen Bedingungen sich ein solches Projekt inmitten alternativer Vernunftkonzepte, basaler und radikaler Einwände sowie postidealistischer Vernunftkritik als ein kooperations- und konkurrenzfähiges Unternehmen bewähren kann. Dazu entwickelt der Autor unter dem Stichpunkt „reflektierter Perspektivismus“ das Programm einer perspektivistischen Metaphilosophie, die den Hintergrundparametern hinter den philosophischen Positionierungen – forschungsprogrammatische Festlegungen (in Anlehnung an Imre Lakatos), Ansprüche und (Wissens-)Ziele – nachspürt und dadurch die Möglichkeiten und Grenzen der verschiedenen Projekte offenlegt. ||| -/- [ENG] Michael Lewin’s book is not only concerned with philosophical-historical perspectives of research on Kant and Fichte, but also with the matter itself: the concept of reason in the narrower sense as a potentially well-grounded research program that can be continued in contemporary contexts. In this, various theoretical structures related to the manifold types and functions of ideas are analyzed, by means of which reason controls the understanding and will, and becomes selfreflexive. After the examination of seven types of ideas in Kant and their systematization in Fichte’s work based on the fact-act (the self-positing of pure reason), the question is discussed as to whether, how and under what conditions such a project can prove itself as a cooperative and competitive enterprise in the midst of alternative concepts of reason, fundamental and radical objections and post-idealistic criticism of reason. To this end, the author develops the program of a perspectivistic metaphilosophy under the heading of »reflected perspectivism«, which traces the background parameters behind the philosophical positionings – research-programmatic determinations (following Imre Lakatos), demands and (knowledge) goals – and thereby reveals the possibilities and limits of the various projects.

Apophaticism -- the view that God is both indescribable and inconceivable -- is one of the great medieval traditions of philosophical thought about God, but it is largely overlooked by analytic philosophers of religion. This paper attempts to rehabilitate apophaticism as a serious philosophical option. We provide a clear formulation of the position, examine what could appropriately be said and thought about God if apophaticism is true, and consider ways to address the charge that apophaticism is self-defeating. In so doing (...) we draw on recent work in the philosophy of language, touching on issues such as the nature of negation, category mistakes, fictionalism, and reductionism. (shrink)

This paper explores Christian contemplative meditation, focusing on the prayer of Recollection as it is developed especially by Evelyn Underhill and St. Teresa of Avila. It outlines the practice and explores possible theoretical and therapeutic dynamics, including some comparative reflections of this form of Christian meditation with Buddhist Samatha Vipassanā meditation and Mindfulness Based Cognitive Therapy. It also draws on the transpersonal theory of philosopher Michael Washburn, in exploring resistances, obstacles, and goals of such mystical practices.

Traditionally, species have been treated as classes. In fact they may be considered individuals. The logical term “individual” has been confused with a biological synonym for “organism.” If species are individuals, then: 1) their names are proper, 2) there cannot be instances of them, 3) they do not have defining properties, 4) their constituent organisms are parts, not members. “ Species " may be defined as the most extensive units in the natural economy such that reproductive competition occurs among their (...) parts. Species are to evolutionary theory as firms are to economic theory: this analogy resolves many issues, such as the problems of “reality” and the ontological status of nomenclatorial types. (shrink)

Sceptical theists--e.g., William Alston and Michael Bergmann--have claimed that considerations concerning human cognitive limitations are alone sufficient to undermine evidential arguments from evil. We argue that, if the considerations deployed by sceptical theists are sufficient to undermine evidential arguments from evil, then those considerations are also sufficient to undermine inferences that play a crucial role in ordinary moral reasoning. If cogent, our argument suffices to discredit sceptical theist responses to evidential arguments from evil.

This is an engaging and accessible introduction to the Nicomachean Ethics, Aristotle's great masterpiece of moral philosophy. Michael Pakaluk offers a thorough and lucid examination of the entire work, uncovering Aristotle's motivations and basic views while paying careful attention to his arguments. The chapter on friendship captures Aristotle's doctrine with clarity and insight, and Pakaluk gives original and compelling interpretations of the Function Argument, the Doctrine of the Mean, courage and other character virtues, Akrasia, and the two treatments of (...) pleasure. There is also a useful section on how to read an Aristotelian text. This book will be invaluable for all student readers encountering one of the most important and influential works of Western philosophy. (shrink)

What is the status of research on implicit bias? In light of meta-analyses revealing ostensibly low average correlations between implicit measures and behavior, as well as various other psychometric concerns, criticism has become ubiquitous.

Should we regret the fact that we are often more emotionally resilient in response to the deaths of our loved ones than we might expect -- that the suffering associated with grief often dissipates more quickly and more fully than we anticipate? Dan Moller ("Love and Death") argues that we should, because this resilience epistemically severs us from our loved ones and thereby "deprives us of insight into our own condition." I argue that Moller's conclusion is correct despite resting on (...) a mistaken picture of the nature and significance of grief. Unlike Moller, I contend that grief is a composite emotional process, rather than a single mental state; that grief is a species of emotional attention rather than perception; and that grief is a form of activity directed at placing our relationships with the deceased on new terms. It is precisely because grief has these three features that it facilitates the scrutiny of our practical identities and thus fosters self-knowledge and self-understanding. (shrink)

I defend the principle of Phenomenal Conservatism, on which appearances of all kinds generate at least some justification for belief. I argue that there is no reason for privileging introspection or intuition over perceptual experience as a source of justified belief; that those who deny Phenomenal Conservatism are in a self-defeating position, in that their view cannot be both true and justified; and that thedemand for a metajustification for Phenomenal Conservatism either is an easily met demand, or is an unfair (...) or question-begging one.

Philosophy and Phenomenological Research, EarlyView.

Michael Sandel's opposition to the project of human enhancement is based on an argument that centres on the notion of giftedness. Sandel claims that by trying to ?make better people? we fall prey to, and encourage, an attitude of mastery and thus lose, or diminish, our appreciation of the giftedness of life. Sandel's position and the underlying argument have been much criticised. In this paper I will try to make sense of Sandel's reasoning and give an account of giftedness (...) that defends its relevance for the ethical assessment of the human enhancement project. In order to do so, I will also look at virtue-related notions, such as gratitude and humility, and distinguish the gifted from the merely given. The failure to acknowledge this distinction gives rise to one of the most common objections to Sandel's argument. Other objections will be shown to rest on similar misunderstandings. (shrink)

This article offers a novel, conservative account of material constitution, one that incorporates sortal essentialism and features a theory of dominant sortals. It avoids coinciding objects, temporal parts, relativizations of identity, mereological essentialism, anti-essentialism, denials of the reality of the objects of our ordinary ontology, and other departures from the metaphysic implicit in ordinary ways of thinking. Defenses of the account against important objections are found in Burke 1997, 2003, and 2004, as well as in the often neglected six paragraphs (...) that conclude section V of this article. (shrink)

The best accuracy arguments for probabilism apply only to credence functions with finite domains, that is, credence functions that assign credence to at most finitely many propositions. This is a significant limitation. It reveals that the support for the accuracy-first program in epistemology is a lot weaker than it seems at first glance, and it means that accuracy arguments cannot yet accomplish everything that their competitors, the pragmatic (Dutch book) arguments, can. In this paper, I investigate the extent to which (...) this limitation can be overcome. Building on the best arguments in finite domains, I present two accuracy arguments for probabilism that are perfectly general—they apply to credence functions with arbitrary domains. I then discuss how the arguments’ premises can be challenged. We will see that it is particularly difficult to characterize admissible accuracy measures in infinite domains. (shrink)

There are at least twelve major virtues of good theories: evidential accuracy, causal adequacy, explanatory depth, internal consistency, internal coherence, universal coherence, beauty, simplicity, unification, durability, fruitfulness, and applicability. These virtues are best classified into four classes: evidential, coherential, aesthetic, and diachronic. Each virtue class contains at least three virtues that sequentially follow a repeating pattern of progressive disclosure and expansion. Systematizing the theoretical virtues in this manner clarifies each virtue and suggests how they might have a coordinated and cumulative (...) role in theory formation and evaluation across the disciplines—with allowance for discipline specific modification. An informal and flexible logic of theory choice is in the making here. Evidential accuracy, according to my systematization, is not a largely isolated trait of good theories, as some have made it out to be. Rather, it bears multifaceted relationships, constituting significant epistemic entanglements, with other theoretical virtues. (shrink)

The psychological and neurobiological processes underlying moral judgement have been the focus of many recent empirical studies1–11. Of central interest is whether emotions play a causal role in moral judgement, and, in parallel, how emotion-related areas of the brain contribute to moral judgement. Here we show that six patients with focal bilateral damage to the ventromedial prefrontal cortex (VMPC), a brain region necessary for the normal generation of emotions and, in particular, social emotions12–14, produce an abnor- mally ‘utilitarian’ pattern of (...) judgements on moral dilemmas that pit compelling considerations of aggregate welfare against highly emotionally aversive behaviours (for example, having to sacrifice one person’s life to save a number of other lives)7,8. In contrast, the VMPC patients’ judgements were normal in other classes of moral dilemmas. These findings indicate that, for a selective set of moral dilemmas, the VMPC is critical for normal judgements of right and wrong. The findings support a necessary role for emotion in the generation of those judgements. (shrink)

Disjunctivists (Hinton 1973, Snowdon 1990, Martin 2002, 2006) often motivate their approach to perceptual experience by appealing in part to the claim that in cases of veridical perception, the subject is directly in contact with the perceived object. When I perceive a table, for example, there is no table-like sense-impression that stands as an intermediary between the table and me. Nor am I related to the table as I am to a deer when I see its footprint in the snow. (...) I do not experience the table by experiencing some- thing else over and above the table and its facing surface. I see the facing surface of the table directly. (shrink)

Around 540 million years ago there was a sudden, dramatic adaptive radiation known as the Cambrian Explosion. This event marked the origin of almost all of the phyla (major lineages characterized by fundamental body plans) of animals that would ever live on earth, as well the appearance of many notable features such as rigid skeletons and other hard parts, complex jointed appendages, eyes, and brains. This radical evolutionary event has been a major puzzle for evolutionary biologists since Darwin, and while (...) our understanding of it has recently improved with new fossil finds, richer molecular phylogenies, and better grasp of ecological, evolutionary, and developmental processes generally, unanswered questions remain. In this paper I argue that a basic cognitive toolkit for embodied, object-oriented, spatial cognition (what I call Basic Cognitive Embodiment) is a practical necessity for control of a large, mobile, complexly articulated body in space. This hypothesis allows us to relate the complexification of animal bodies to the complexification of perception, cognition and behavior in a way that can help to fill in gaps in our emerging picture of the Cambrian Explosion, as well as shed light on the deep evolutionary origins of the mind.

Grief is our emotional response to the deaths of intimates, and so like many other emotional conditions, it can be appraised in terms of its rationality. A philosophical account of grief's rationality should satisfy a contingency constraint, wherein grief is neither intrinsically rational nor intrinsically irrational. Here I provide an account of grief and its rationality that satisfies this constraint, while also being faithful to the phenomenology of grief experience. I begin by arguing against the best known account of grief's (...) rationality, Gustafson's strategic or forward-looking account, according to which the practical rationality of grief depends on the internal coherence of the component attitudes that explain the behaviors caused by grief, and more exactly, on how these attitudes enable the individual to realize states of affairs that she desires. While I do not deny that episodes of grief can be appraised in terms of their strategic rationality, I deny that strategic rationality is the essential or fundamental basis on which grief's rationality should be appraised. In contrast, the heart of grief's rationality is backward-looking. That is, what primarily makes an episode of grief rational qua grief is the fittingness of the attitudes individuals take toward the experience of a lost relationship, attitudes which in turn generate the desires and behaviors that constitute bereavement. Grief thus derives its essential rationality from the objects it responds to, not from the attitudes causally downstream from that response, and is necessarily irrational when the behaviors that constitute an individual's grieving are inappropriate to the object of that grief. So while the strategic rationality of an episode of grief contributes to whether it is on the whole rational, no episode of grief can be rational unless the actions that constitute grieving accurately gauge the change in a person's normative situation wrought by the loss of her relationship with the deceased.

On the most popular account of material constitution, it is common for a material object to coincide precisely with one or more other material objects, ones that are composed of just the same matter but differ from it in sort. I argue that there is nothing that could ground the alleged difference in sort and that the account must be rejected.

Different people reason differently, which means that sometimes they reach different conclusions from the same evidence. We maintain that this is not only natural, but rational. In this essay we explore the epistemology of that state of affairs. First we will canvass arguments for and against the claim that rational methods of reasoning must always reach the same conclusions from the same evidence. Then we will consider whether the acknowledgment that people have divergent rational reasoning methods should undermine one’s confidence (...) in one’s own reasoning. Finally we will explore how agents who employ distinct yet equally rational methods of reasoning should respond to interactions with the products of each others’ reasoning. We find that the epistemology of multiple reasoning methods has been misunderstood by a number of authors writing on epistemic permissiveness and peer disagreement. (shrink)

I review Michael T. Ferejohn's "Formal Causes: Definition, Explanation, and Primacy in Socratic and Aristotelian Thought".

For two ideally rational agents, does learning a finite amount of shared evidence necessitate agreement? No. But does it at least guard against belief polarization, the case in which their opinions get further apart? No. OK, but are rational agents guaranteed to avoid polarization if they have access to an infinite, increasing stream of shared evidence? No.

Scholars, journalists, and activists working on climate change often distinguish between “individual” and “structural” approaches to decarbonization. The former concern choices individuals can make to reduce their “personal carbon footprint” (e.g., eating less meat). The latter concern changes to institutions, laws, and other social structures. These two approaches are often framed as oppositional, representing a mutually exclusive forced choice between alternative routes to decarbonization. After presenting representative samples of this oppositional framing of individual and structural approaches in environmental communication, we (...) identify four problems with oppositional thinking and propose five ways to conceive of individual and structural reform as symbiotic and interdependent.

Rivka Weinberg advances an error theory of ultimate meaning with three parts: (1) a conceptual analysis, (2) the claim that the extension of the concept is empty, and (3) a proposed fitting response, namely being very, very sad. Weinberg’s conceptual analysis of ultimate meaning involves two features that jointly make it metaphysically impossible, namely (i) the separateness of activities and valued ends, and (ii) the bounded nature of human lives. Both are open to serious challenges. We offer an internalist alternative (...) to (i) and a relational alternative to (ii). We then draw out implications for (2) and conclude with reasons to be cheerful about the prospects of a meaningful life. (shrink)

We identify several ongoing debates related to implicit measures, surveying prominent views and considerations in each debate. First, we summarize the debate regarding whether performance on implicit measures is explained by conscious or unconscious representations. Second, we discuss the cognitive structure of the operative constructs: are they associatively or propositionally structured? Third, we review debates whether performance on implicit measures reflects traits or states. Fourth, we discuss the question of whether a person’s performance on an implicit measure reflects characteristics of (...) the person who is taking the test or characteristics of the situation in which the person is taking the test. Finally, we survey the debate about the relationship between implicit measures and (other kinds of) behavior. (shrink)

Debunking skeptics claim that our moral beliefs are formed by processes unsuited to identifying objective facts, such as emotions inculcated by our genes and culture; therefore, they say, even if there are objective moral facts, we probably don’t know them. I argue that the debunking skeptics cannot explain the pervasive trend toward liberalization of values over human history, and that the best explanation is the realist’s: humanity is becoming increasingly liberal because liberalism is the objectively correct moral stance.

The deaths of those on whom our practical identities rely generate a sense of disorientation or alienation from the world seemingly at odds with life being meaningful. In the terms put forth in Cheshire Calhoun’s recent account of meaningfulness in life, because their existence serves as a metaphysical presupposition of our practical identities, their deaths threaten to upend a background frame of agency against which much of our choice and deliberation takes place. Here I argue for a dual role for (...) grief in addressing this threat to life’s meaningfulness. Inasmuch as grief’s object is the loss of our relationship with the deceased as it was prior to their death, grief serves to alert us to the threat to our practical identities that their deaths pose to us and motivates us to defuse this threat by revising our practical identities to reflect the modification in our relationship necessitated by their deaths. Simultaneously, the emotional complexity and richness of grief episodes provides an abundance of normative evidence regarding our relationship with the deceased and our practical identities, evidence that can enable us to re-establish our practical identities and thereby recover a sense of our lives as meaningful.
