Possible worlds models of belief have difficulties accounting for unawareness, the inability to entertain (and hence believe) certain propositions. Accommodating unawareness is important for adequately modelling epistemic states, and representing the informational content to which agents have in principle access given their explicit beliefs. In this paper, I develop a model of explicit belief, awareness, and informational content, along with an sound and complete axiomatisation. I furthermore defend the model against the seminal impossibility result of Dekel, Lipman and Rustichini, according (...) to which three intuitive conditions preclude non-trivial unawareness on any possible worlds model of belief.

This paper begins with a puzzle regarding Lewis' theory of radical interpretation. On the one hand, Lewis convincingly argued that the facts about an agent's sensory evidence and choices will always underdetermine the facts about her beliefs and desires. On the other hand, we have several representation theorems—such as those of (Ramsey 1931) and (Savage 1954)—that are widely taken to show that if an agent's choices satisfy certain constraints, then those choices can suffice to determine her beliefs and desires. In (...) this paper, I will argue that Lewis' conclusion is correct: choices radically underdetermine beliefs and desires, and representation theorems provide us with no good reasons to think otherwise. Any tension with those theorems is merely apparent, and relates ultimately to the difference between how 'choices' are understood within Lewis' theory and the problematic way that they're represented in the context of the representation theorems. For the purposes of radical interpretation, representation theorems like Ramsey's and Savage's just aren't very relevant after all. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Comments on “Moral Complicity in Induced Pluripotent Stem Cell Research”W. Malcolm Byrnes, Ph.D. and Edward J. FurtonIn his article titled “Moral Complicity in Induced Pluripotent Stem Cell Research,” Mark T. Brown (2009) unfortunately mischaracterizes my ethical analysis of the use of induced pluripotent stem (iPS) cells for replacement therapies, or treatments (Byrnes 2008). In my paper, which Brown cites, I argue that, just as it is ethically acceptable (...) for parents to allow their children and themselves to be immunized using vaccines produced by cell lines derived from human fetuses aborted in the past, it is also acceptable for persons in the future to benefit from treatments that use iPS cells validated using human embryonic stem (ES) cell lines [End Page 202] derived in the past. The assumption I make is that iPS cells would have to be shown to be functionally equivalent to human ES cells—i.e., validated—before they could be used for cell replacement treatments. (If it turns out that this assumption is incorrect, and primate or even mouse ES cells can be used for the validation, then all residual ethical problems will disappear and there will be no ethical problems whatsoever associated with iPS cells.) I wrote:... [I]n both cases, the origin of the treatment is in a one-time event: either the one-time use of aborted fetuses to obtain cell lines (e.g., MRC-5 and WI- 38) to grow weakened virus strains for vaccine production, or the one-time destruction of human embryos to validate iPS cells, which then effectively replace embryonic stem cells. In the latter case, if no additional embryonic stem cell lines are derived, then derivation of the existing lines could be considered a “one-time” event in the past, albeit an event that extended over a several-year period(Byrnes 2008, p. 287, emphasis added).Note the phrase “if no additional embryonic stem cell lines are derived.” The derivation of ES cell lines inherently involves destruction of embryos; indeed, that is why many people, including me, are opposed to human ES cell research. In my article, I am arguing that, if no additional ES cell lines are derived, then no additional human embryos will be destroyed, and the destruction of human embryos will lie in the past. In this case, embryo destruction could be considered a past event, just as the abortion of a human fetus from which vaccine-producing cell lines were derived is a past, albeit tragic, event.In the process of building his argument that proponents of iPS cell research are morally complicit in embryo destruction, Brown (2009, p. 15) casts me as being in favor of the “derivation of new embryonic stem [cell lines].” This is the exact opposite of my position. In fact, I am opposed to further destruction of human embryos. I believe that the hundreds of ES cell lines already in existence are more than sufficient to validate iPS cells and so no additional lines need to be derived. This means that no additional human embryos will need to be destroyed.Apparently based on the misperception that I support future destruction of human embryos, Brown concludes that “Byrnes’s endorsement of ongoing iPSC validation studies would seem to implicate him and those who follow his lead in formal and material complicity in what they perceive as moral evil” (p. 16). He writes that “explicit formal complicity would attach because he [Byrnes] knowingly and intentionally recommends that embryos be killed in order to facilitate a transition to a future in which no more embryos need be destroyed” (p. 16). Additionally, my “followers” and I would be guilty of “proximate material complicity” as well as “remote material complicity” (p. 16). Unfortunately, this broad condemnation is based on a misconception of my actual position.An additional problem involves Brown’s use of a quotation he attributes to me: [End Page 203]Once embryonic stem cells are used to successfully validate iPS cells, they will no longer be needed and their association with iPS cells will lie in the past. Is there not an element of sadness and resignation in accepting something (iPS cells) associated with an unjust act (destruction of an... (shrink)

This essay explores the role of God’s omnipresence in Newton’s natural philosophy, with special emphasis placed on how God is related to space. Unlike Descartes’ conception, which denies the spatiality of God, or Gassendi and Charleton’s view, which regards God as completely whole in every part of space, it is argued that Newton accepts spatial extension as a basic aspect of God’s omnipresence. The historical background to Newton’s spatial ontology assumes a large part of our investigation, but with attention also (...) focused on the details of Newton’s unique approach to these traditional Scholastic conceptions.

An exploratory pilot study with a small homogenous sample of Christian English speaking participants provided support for an alternative research hypothesis that a Christ consciousness contemplation with Heart Prayer of HeartMath techniques was significantly associated with increasing psychophysiological coherence, sense of coherence, spirituality and health perceptions. Participants described feelings of a peaceful place in oneness and connection with Christ. Integrative findings point towards Christ consciousness as an ultimately non-dual process of sensing vibrational resonance radiating from the human heart. Implications for (...) further research are discussed. (shrink)

This integral investigation explored phenomenological and neurophysiologic, individual and collective dimensions of Christian Trinitarian meditation experiences in a volunteer, convenience sample of 10 practicing Christians, 6 men and 4 women, with a mean age of 48 years and an age range from 21 to 85 years. Participants meditated for a minimum period of 15 minutes, during which neurophysiologic data in the form of electroencephalographic (EEG), electromyographic (EMG), blood volume pulse (BVP) and respiratory activity were recorded. A phenomenological analysis indicated that (...) the meditation process generally involved a movement from body to mind to spirit as evident in reports of an increasingly relaxed, contented and focused state of consciousness characterised by Christian Trinitarian imagery, wonder, surrender, peace, bliss, openness and formlessness. The neuropsychological findings indicated significant increases, from baseline to meditation recordings, in the alpha and beta range, accompanied by increasing mean trends in the theta and gamma range, and decreasing mean trends in the delta range, EMG, BVP and respiration. Integrative findings indicated the practical theological value of small doses of Christian Trinity meditation to enhance spiritual life for those forms of waking, thinking, conscious behaviour needed in everyday world involvement and healing. Findings were discussed in relation to further integrative investigations and interventions with practical theological implications. (shrink)

The research was generally motivated by a dearth of studies on joy, and particularly inspired by a book of joy celebrating the inter-spiritual dialogue between the Dalai Lama and Desmond Tutu. Its aim was to investigate whether the direct contemplation of joy would be associated with improvements in psychophysiological coherence, spirituality and various positive emotions and feelings. Integrative quantitative and qualitative findings emerging from a small pilot study, including a convenience sample of six participants with a mean age of 42 (...) years and age range of 25-69 years, supported the research hypothesis. Significant quantitative increases in psychophysiological coherence, spirituality and positive feelings were coherently and consistently supported by participants' individual and collective experiences. Integrative discussion amplified the paradoxical theme of joy through suffering in human emotional and spiritual life. (shrink)

One of the more obscure arguments for Rawls’ difference principle dubbed ‘the Pareto argument for inequality’ has been criticised by G. A. Cohen (1995, 2008) as being inconsistent. In this paper, we examine and clarify the Pareto argument in detail and argue (1) that justification for the Pareto principles derives from rational selfinterest and thus the Pareto principles ought to be understood as conditions of individual rationality, (2) that the Pareto argument is not inconsistent, contra Cohen, and (3) that the (...) kind of bargaining model required to arrive at the particular unequal distribution that the difference principle picks out is a model that is not based on bargaining according to one’s threat advantage.

This is, to the best of my knowledge, the first published attempt at a rigorous logical formalization of a passage in Leibniz's Monadology. The method we followed was suggested by Johannes Czermak.

In this paper, we present a formalism for handling polysemy in spatial expressions based on supervaluation semantics called standpoint semantics for polysemy (SSP). The goal of this formalism is, given a prepositional phrase, to define its possible spatial interpretations. For this, we propose to characterize spatial prepositions by means of a triplet ⟨ image schema, semantic feature, spatial axis⟩⁠. The core of SSP is predicate grounding theories, which are formulas of a first-order language that define a spatial preposition through the (...) semantic features of its trajector and landmark. Precisifications are also established, which are a set of formulae of a qualitative spatial reasoning formalism that aims to provide the spatial characterization of the trajector with respect to the landmark. In addition to the theoretical model, we also present results of a computational implementation of SSP for the preposition ‘in’. (shrink)

This paper proposes that there is common ground between H.J. Rose’s A Handbook of Greek Mythology and Robert Graves’s The Greek Myths, in that both seem to think that it is a bad idea to meet a certain demand: to provide a handbook that is reliable, easy to consult, and suitable for students of certain literary tastes.

This paper reflects on an article that appeared after the death of A.J. Ayer, which complains about what British philosophers focus on. I propose that the content of the philosophy curriculum can be predicted from a rational actor model.

This paper pays tribute to the distinguished legal and political philosopher Joseph Raz, who recently passed away. I present a response to Donald Davidson on conceptual schemes which tries to imitate Raz’s writing style, which attracts me despite the difficulties it poses. The response includes a definition.

Modern bioethics is clearly dominated by deontologists who believe that we have some way of identifying morally correct and incorrect acts or rules besides taking account of their consequences. Robert M. Veatch is one of the most outspoken of those numerous modern medical ethicists who agree in rejecting all forms of teleological, utilitarian, or consequentialist ethical theories. This paper examines his critique of utilitarianism and shows that the utilitarianism of John Stuart Mill is either not touched at all by his (...) critique or can be defended against it. This article argues that the dominant deontological majority is mistaken and that a utilitarian theory of moral action very much like Mill’s is precisely what is needed by modern medical ethics and by those medical practitioners who are resolved to practice medicine in a reasonable and morally acceptable manner.

This paper considers whether the saying, “It’s who you know, not what you know” can be used instead of jargon-laden studies of inequality. I argue that it is not a good replacement in some cases and present a challenge to standard Bourdieusian explanations of inequality in some fields. The paper is written as a pastiche of the distinguished political philosopher Joseph Raz.

This paper contains a brief pastiche of analytic philosopher Carrie Ichikawa Jenkins, responding to the sociological theories of Pierre Bourdieu.

This is a review of Thomas Jay Oord’s book on The Uncontrolling Love of God in which he develops a very persuasive and highly original process account of how God’s love, power, and providence relate to matters of human freedom, randomness in nature and history, natural laws, miracles, and evil. This review summarizes the main points in each of his eight chapters and offers a few critical and constructive comments on them.

A summary and brief critique of two closely related books by Thomas Jay Oord.

This paper investigates Newton’s ontology of space in order to determine its commitment, if any, to both Cambridge neo-Platonism, which posits an incorporeal basis for space, and substantivalism, which regards space as a form of substance or entity. A non-substantivalist interpretation of Newton’s theory has been famously championed by Howard Stein and Robert DiSalle, among others, while both Stein and the early work of J. E. McGuire have downplayed the influence of Cambridge neo-Platonism on various aspects of Newton’s own spatial (...) hypotheses. Both of these assertions will be shown to be problematic on various grounds, with special emphasis placed on Stein’s influential case for a non-substantivalist reading. Our analysis will strive, nonetheless, to reveal the unique or forward-looking aspects of Newton’s approach, most notably, his critical assessment of substance ontologies, that help to distinguish his theory of space from his neo-Platonic contemporaries and predecessors.

J.G. Frazer tells us about a last resort technique which Cambodian hunters use when they have caught nothing in their nets. The “technique” is they act as if they themselves have got caught in the net. Frazer explains this as the consequence of magical thinking, but I propose a different explanation.

In this paper, I present two puzzles arising from J.M. Coetzee’s novel Elizabeth Costello, a fiction which is closely connected to analytic philosophy.

This paper presents an objection to the theory of names according to which what a name refers to is determined by a description that the speaker or writer associates with that name. Some names are associated with paradoxical descriptions. I use the reputations of Henry Sidgwick and J.M.E. McTaggart to illustrate this problem.

This is a one page handout, presenting a puzzle from J.G. Frazer regarding why, to become the priest of Diana at Nemi, one had to first break a bough in the sacred grove.

Traditional hedonists like Epicurus, Bentham and Sidgwick were quantitative hedonists who assumed that pleasures and pains differ, not just from each other, but also from other pleasures and pains only in such quantitatively measurable ways as intensity, duration, and nearness or remoteness in time. They also differ with respect to their sources or causes. John Stuart Mill introduced an interesting and important complication into the modern theory of hedonism by insisting that pleasures also differ qualitatively as well as quantitatively. This (...) article thoroughly and critically examines Mill’s attempt to explain what qualitative differences might mean, and it proposes, defends, and extends a plausible theory of qualitative differences.

This inquiry is addressed to two questions: (1) what if any logical relations might exist between the concepts of desire and action (as they and the distinctions to which they commit us are ensconced in ordinary parlance), and (2) what if any causal or significant non-causal (i.e., material) relations might ever exist between instances of desire and action? -/- It is held that any credible move to deal with such questions must initially, and at some length, specify the employment conditions (...) for the terms 'want' and 'desire'. This is accomplished in the first two chapters wherein a set of premises is generated for the argument of the inquiry which is presented in full and concluded in the third and final chapter. Premises generated devolve from treatment of the following major topics: (a) the grammar of 'want' and 'desire', (b) the ontological status of wants, (c) first-person and third-person want ascriptions, (d) the sorts of things which may be desired (desiderabilia), (e) wants and lacks, (f) wants and wishes, (g) the 'conflicts' of desires and reason and desire, (h) four major candidates for logical relations between wants and acts, (i) the issue of causation, and (j) the placement of Desire in an adequate ontology of persons. -/- It is argued that every major candidate for a logical relation between wants and acts (or our warrant for believing that such a connection exists) breaks down upon analysis; that little warrant exists for construing wants as causes of acts; that wants and acts are related in significant non-logical and non-causal (i.e., material) respects; and that any fully adequate theory of human action must undertake ontology, placing the category of Desire squarely in the foreground. This project represents neither a general theory of desire nor a general theory of human action. It is rather conceived as a propaedeutic to any such inquiry. It is essentially revisionist in intent, setting out on the one hand to challenge existing claims about wants and acts and, on the other hand, proposing a more satisfactory approach to the issue. In no sense is it suggested that recent Anglo-American contributions are without merit. It is rather argued that they are often inadequate contributions vis-a-vis the larger requirements for an adequate theory of human action. (shrink)

This is an excellent though largely uncritical introduction to, and defence of, Robert Nozick‟s Anarchy, State and Utopia (New York: Basic Books, 1974). It is also quite a good introduction to libertarianism. It is full of good arguments. I shall confine myself to critical remarks. My responses are mainly in the order that matters arise in the book.

This book presents Robert S. Hartman’s formal theory of value and critically examines many other twentieth century value theorists in its light, including A.J. Ayer, Kurt Baier, Brand Blanshard, Paul Edwards, Albert Einstein, William K. Frankena, R.M. Hare, Nicolai Hartmann, Martin Heidegger, G.E. Moore, P.H. Nowell-Smith, Jose Ortega y Gasset, Charles Stevenson, Paul W. Taylor, Stephen E. Toulmin, and J.O. Urmson.

One of the cornerstones of western theology is the doctrine of divine omnipotence. God is traditionally conceived of as an omnipotent or all-powerful being. However, satisfactory analyses of omnipotence are notoriously elusive. In this paper, I first consider some simple attempts to analyze omnipotence, showing how each fails. I then consider two more sophisticated accounts of omnipotence. The first of these is presented by Edward Wierenga; the second by Thomas Flint and Alfred Freddoso. I argue that both of these (...) accounts fail. Finally, I propose and defend a novel account of omnipotence. (shrink)

The author interprets three stories from recently Neolithic cultures (Melanesian, African Bushman, and Inuit) and a fourth story from an oral tradition of Haitian women. All four are about women and perhaps, judging by their content, composed by women. The author trained with Edward Whitmont and developed his interpretation technique in decades of practice with dreams as a Jungian analyst. He adds a new tool, the use of repetition, in which the same point is made by a series of (...) different details. Repetition provides an internal test for the accuracy of an interpretation. The author updates Jung’s concept of archetypes to incorporate an understanding of Darwinian evolution (which Jung lacked), new knowledge of the function of genes, and new knowledge of the emergence of complexity in dynamic and adaptive systems. He compares his interpretations of the four stories with other scholars’ interpretations, in particular the extraordinary work of Michael Wessels on African Bushman legends. Though Wessels criticized Jung for imposing his ‘colonial’ theory of universal archetypes, both Jung and Wessels insisted that interpretation requires a dialogue between two agents in which both are subjects, neither being dominated or objectified. In the four stories, the author shows, symbolic consciousness began with women. The anthropologist Chris Knight proposed something similar in 1991 in his controversial book Blood Relations: Menstruation and the Origins of Culture. (shrink)

For decades scholars thought they knew Hume's position on the existence of causes and objects he was a sceptic. However, this received view has been thrown into question by the `new readings of Hume as a sceptical realist.

Riječ “intelektualac” francuskog je porijekla, nastala krajem 19. vijeka. Stvorena tokom afere Dreyfus, uglavnom se odnosi na one mislioce koji su spremni da interveniraju u javnom forumu, čak i ako to znači da sebe izlažu riziku (Le Sueur 2001:2). Teoretičari kao što su Edward Said, Paul Ricoeur, Jean-Paul Sartre i Michael Waltzer dali su doprinos diskusiji o intelektualcima: intelektualca Said vidi kao kritički nastrojenog autsajdera, Ricoeur kao političkog edukatora, Sartre kao čovjeka od akcije, a Waltzer kao brižnog insajdera. Opisati (...) intelektualca na ovaj način, pak, ne spominje prostor unutar kojeg intelektualac djeluje, tj. građansko društvo. Upravo se u takvom prostoru ljudskog udruživanja i odnosnih mreža može promovirati kultura dijaloga, tolerancije, umjerenosti i uzajamno korisnog rješavanja sukoba, upravo onakva kultura kakva otjelotvorava stavove i vrijednosti demokratizacije. Mada intelektualac, onakav kakav je gore opisan, igra značajnu ulogu u održavanju dobro razvijenih demokratskih društava, u postkonfliktnim društvima, kakva su i kosovsko i bosanskohercegovačko, pojavljuje se potreba za intelektualcem koji je više od pukog kritičara društva, edukatora, čovjeka od akcije i saosjećajnog pojedinca. I tu na scenu stupa hiperintelektualac. Najupečatljivija karakteristika hiperintelektualca je možda upravo stepen u kojem se intelektualac bavi društvenom kritikom, političkim obrazovanjem, akcijom i “insajderizmom”, ne kao ideolog, već kao nestranačka fi gura. Društvena kritika i političko obrazovanje hiperintelektualca manifestiraju se na nestranački način, tako da se jasno čuje sve što je moguće i napadati i braniti, i sa jedne i sa druge strane.

Plant diseases are numerous in the world of agriculture. These diseases cause a lot of trouble to most farmers. Among these common diseases, we single out the diseases that affect the Passion fruit, which is affected by about seven diseases, with different symptoms for each disease. Today, technology is facilitating human life in all areas of life, and among these facilities are expert system, a computer program that uses artificial-intelligence methods to solve problems within a specialized domain that ordinarily requires (...) human expertise. The first expert system was developed in 1965 by Edward Feigen Baum and Joshua Lederberg of Stanford University in California, U.S. Dendral, as their expert system was later known, was designed to analyses chemical compounds. Expert systems now have commercial applications in fields as diverse as medical diagnosis, petroleum engineering, and financial investing and other areas, and with reference to expert systems and their importance to humans, an integrated expert system has been created in the agricultural field that diagnoses Passion diseases using CLIPS Expert System language. The system was used to design and implement the proposed expert system. The system facilitates the diagnosis of Passion -related diseases. There is no doubt that this expert system will help farmers and those involved in the agricultural field to diagnose Passion -related diseases. Objectives: is to help farmers diagnose Passion diseases in the correct way and how to treat these diseases. Method: The system contains a program project that diagnoses 7 diseases that affect Passion and the seven diseases are: Brown spot, Septoria spot, Root and crown rot, Fusarium wilt, Anthracnose, Woodiness virus, Scab. Results: The expert system was evaluated by farmers and praised for helping them with it. Conclusion: The expert system for diagnosing Passion diseases is effective and usable. (shrink)

This essay from 1999, republished in Notre Dame Magazine online in July 2023, explores how the 1950s were a time of fundamental transformations in American society, a time when the United States went fully megatechnic. The hugely increased power of military, corporate-industrial and “big science” institutions developed during the 1950s signaled the transformation to megatechnic America, with atomic bombs and nuclear testing, automobiles and televisions as key symbols of that transformation. Figures such as J. Robert Oppenheimer and Edward Teller (...) illustrated the battle between national security dictates controlling nuclear bomb testing and responsible science. -/- Since the Second World War the United States has been problematically guided by a power-oriented culture, which, in the names of national security and convenience, has tended to reshape America toward an increasingly hierarchical model of society based on the system requirements of a machine. This same era gave birth to a generalized economic prosperity in the United States, to the civil rights movement, to feminism, literary and artistic innovations, and to other openings of public equality and freedom. Yet the magnification of bureaucratic-corporate structures in that postwar, cold war prosperity has ultimately tended to restructure America against the basic requirements of democratic community.

Why did such highly abstract ideas as truth, knowledge, or justice become so important to us? What was the point of coming to think in these terms? This book presents a philosophical method designed to answer such questions: the method of pragmatic genealogy. Pragmatic genealogies are partly fictional, partly historical narratives exploring what might have driven us to develop certain ideas in order to discover what these do for us. The book uncovers an under-appreciated tradition of pragmatic genealogy which cuts (...) across the analytic-continental divide, running from the state-of-nature stories of David Hume and the early genealogies of Friedrich Nietzsche to recent work in analytic philosophy by Edward Craig, Bernard Williams, and Miranda Fricker. However, these genealogies combine fictionalizing and historicizing in ways that even philosophers sympathetic to the use of state-of-nature fictions or real history have found puzzling. To make sense of why both fictionalizing and historicizing are called for, the book offers a systematic account of pragmatic genealogies as dynamic models serving to reverse-engineer the points of ideas in relation not only to near-universal human needs, but also to socio-historically situated needs. This allows the method to offer us explanation without reduction and to help us understand what led our ideas to shed the traces of their practical origins. Far from being normatively inert, moreover, pragmatic genealogy can affect the space of reasons, guiding attempts to improve our conceptual repertoire by helping us determine whether and when our ideas are worth having.

Nonreductive physicalism states that actions have sufficient physical causes and distinct mental causes. Nonreductive physicalism has recently faced the exclusion problem, according to which the single sufficient physical cause excludes the mental causes from causal efficacy. Autonomists respond by stating that while mental-to-physical causation fails, mental-to-mental causation persists. Several recent philosophers establish this autonomy result via similar models of causation :1031–1049, 2016; Zhong, J Philos 111:341–360, 2014). In this paper I argue that both of these autonomist models fail on account (...) of the problem of Edwards’s Dictum. However, I appeal to foundational principles of action theory to resuscitate mental-to-mental causation in a manner that is consistent with the models of causation endorsed by these autonomists.

Decisions are made under uncertainty when there are distinct outcomes of a given action, and one is uncertain to which the act will lead. Decisions are made under indeterminacy when there are distinct outcomes of a given action, and it is indeterminate to which the act will lead. This paper develops a theory of (synchronic and diachronic) decision-making under indeterminacy that portrays the rational response to such situations as inconstant. Rational agents have to capriciously and randomly choose how to resolve (...) the indeterminacy relevant to a given choice-situation, but such capricious choices once made constrain how they will choose in the future. The account is illustrated by the case of self-interested action in situations where it is indeterminate whether you yourself will survive to benefit or suffer the consequences. The conclusion emphasizes some distinctive anti-hedging predictions of the account. (shrink)

Might it be that world itself, independently of what we know about it or how we represent it, is metaphysically indeterminate? This article tackles in turn a series of questions: In what sorts of cases might we posit metaphysical indeterminacy? What is it for a given case of indefiniteness to be 'metaphysical'? How does the phenomenon relate to 'ontic vagueness', the existence of 'vague objects', 'de re indeterminacy' and the like? How might the logic work? Are there reasons for postulating (...) this distinctive sort of indefiniteness? Conversely, are there reasons for denying that there is indefiniteness of this sort? (shrink)

Inscrutability arguments threaten to reduce interpretationist metasemantic theories to absurdity. Can we find some way to block the arguments? A highly influential proposal in this regard is David Lewis’ ‘ eligibility ’ response: some theories are better than others, not because they fit the data better, but because they are framed in terms of more natural properties. The purposes of this paper are to outline the nature of the eligibility proposal, making the case that it is not ad hoc, but (...) instead flows naturally from three independently motivated elements; and to show that severe limitations afflict the proposal. In conclusion, I pick out the element of the eligibility response that is responsible for the limitations: future work in this area should therefore concentrate on amending this aspect of the overall theory.

The concept of moral wrongness, many think, has a distinctive kind of referential stability, brought out by moral twin earth cases. This article offers a new account of the source of this stability, deriving it from a metaphysics of content: “substantive” radical interpretation, and first-order normative assumptions. This story is distinguished from extant “reference magnetic” explanations of the phenomenon, and objections and replies are considered.

This article investigates the claim that some truths are fundamentally or really true — and that other truths are not. Such a distinction can help us reconcile radically minimal metaphysical views with the verities of common sense. I develop an understanding of the distinction whereby Fundamentality is not itself a metaphysical distinction, but rather a device that must be presupposed to express metaphysical distinctions. Drawing on recent work by Rayo on anti-Quinean theories of ontological commitments, I formulate a rigourous theory (...) of the notion. In the final sections, I show how this package dovetails with ' interpretationist' theories of meaning to give sober content to thought that some things — perhaps sets, or gerrymandered mereological sums — can be 'postulated into existence'.

In their thought-provoking article, Sedlakova and Trachsel (2023) defend the view that the status—both epistemic and ethical—of Conversational Artificial Intelligence (CAI) used in psychotherapy is complicated. While therapeutic CAI seems to be more than a mere tool implementing particular therapeutic techniques, it falls short of being a “digital therapist.” One of the main arguments supporting the latter claim is that even though “the interaction with CAI happens in the course of conversation… the conversation is profoundly different from a conversation with (...) a human therapist” (Sedlakova and Trachsel 2023, 8). In particular, unlike a human therapist, CAI cannot help its users gain new insight and self-understanding (Sedlakova and Trachsel 2023). We agree that currently available therapeutic CAI cannot be considered a “digital therapist,” however, we think that the issue surrounding the acquisition of new self-understanding in the interaction with therapeutic CAI is more complicated than Sedlakova and Trachsel suggest.

Lewis (1973) gave a short argument against conditional excluded middle, based on his treatment of ‘might’ counterfactuals. Bennett (2003), with much of the recent literature, gives an alternative take on ‘might’ counterfactuals. But Bennett claims the might-argument against CEM still goes through. This turns on a specific claim I call Bennett’s Hypothesis. I argue that independently of issues to do with the proper analysis of might-counterfactuals, Bennett’s Hypothesis is inconsistent with CEM. But Bennett’s Hypothesis is independently objectionable, so we should (...) resolve this tension by dropping the Hypothesis, not by dropping CEM. (shrink)

Worlds where things divide forever ("gunk" worlds) are apparently conceivable. The conceivability of such scenarios has been used as an argument against "nihilist" or "near-nihilist" answers to the special composition question. I argue that the mereological nihilist has the resources to explain away the illusion that gunk is possible.

This paper examines two puzzles of indeterminacy. The first puzzle concerns the hypothesis that there is a unified phenomenon of indeterminacy. How are we to reconcile this with the apparent diversity of reactions that indeterminacy prompts? The second puzzle focuses narrowly on borderline cases of vague predicates. How are we to account for the lack of theoretical consensus about what the proper reaction to borderline cases is? I suggest (building on work by Maudlin) that the characteristic feature of indeterminacy is (...) alethic normative silence, and use this to explain both plurality and lack of consensus. (shrink)

Revisionary theories of logic or truth require revisionary theories of mind. This essay outlines nonclassically based theories of rational belief, desire, and decision making, singling out the supervaluational family for special attention. To see these nonclassical theories of mind in action, this essay examines a debate between David Lewis and Derek Parfit over what matters in survival. Lewis argued that indeterminacy in personal identity allows caring about psychological connectedness and caring about personal identity to amount to the same thing. The (...) essay argues that Lewis's treatment of two of Parfit's puzzle cases—degreed survival and fission—presuppose different nonclassical treatments of belief and desire. (shrink)

Sometimes it is indeterminate what an agent morally ought do. This generates a Decision Ought Challenge—to give moral guidance to agents in such a scenario. This article is a field guide to the options for a theory of the decision ought for cases of indeterminacy.

Joyce (1998) gives an argument for probabilism: the doctrine that rational credences should conform to the axioms of probability. In doing so, he provides a distinctive take on how the normative force of probabilism relates to the injunction to believe what is true. But Joyce presupposes that the truth values of the propositions over which credences are defined are classical. I generalize the core of Joyce’s argument to remove this presupposition. On the same assumptions as Joyce uses, the credences of (...) a rational agent should always be weighted averages of truth value assignments. In the special case where the truth values are classical, the weighted averages of truth value assignments are exactly the probability functions. But in the more general case, probabilistic axioms formulated in terms of classical logic are violated—but we will show that generalized versions of the axioms formulated in terms of non-classical logics are satisfied.

Jeff Paris proves a generalized Dutch Book theorem. If a belief state is not a generalized probability then one faces ‘sure loss’ books of bets. In Williams I showed that Joyce’s accuracy-domination theorem applies to the same set of generalized probabilities. What is the relationship between these two results? This note shows that both results are easy corollaries of the core result that Paris appeals to in proving his dutch book theorem. We see that every point of accuracy-domination defines a (...) dutch book, but we only have a partial converse. (shrink)

Many accounts of structural rationality give a special role to logic. This paper reviews the problem case of clear-eyed logical uncertainty. An account of rational norms on belief that does not give a special role to logic is developed: doxastic probabilism.

Some skeptical theists use Wykstra’s CORNEA constraint to undercut Rowe-style inductive arguments from evil. Many critics of skeptical theism accept CORNEA, but argue that Rowe-style arguments meet its constraint. But Justin McBrayer argues that CORNEA is itself mistaken. It is, he claims, akin to “sensitivity” or “truth-tracking” constraints like those of Robert Nozick; but counterexamples show that inductive evidence is often insensitive. We here defend CORNEA against McBrayer’s chief counterexample. We first clarify CORNEA, distinguishing it from a deeper underlying principle (...) that we dub “CORE.” We then give both principles a probabilistic construal, and show how, on this construal, the counterexample fails.
