The field of AI has undergone a series of transformations, each marking a new phase of development. The initial phase emphasized curation of symbolic models which excelled in capturing reasoning but were fragile and not scalable. The next phase was characterized by machine learning models—most recently large language models (LLMs)—which were more robust and easier to scale but struggled with reasoning. Now, we are witnessing a return to symbolic models as complementing machine learning. Successes of LLMs contrast with their inscrutability, (...) inaccuracy, and hallucinations, which underwrite concerns over the reliability and trustworthiness of these systems, motivating investigations into commonsense reasoning, AI explainability, and formal verification techniques. Moreover, proper assessments of hybrid machine learning/symbolic systems require novel strategies to facilitate comparisons of performance and guide future AI progress. The EDGeS AAAI 2023 Spring symposium brought together researchers focusing on novel assessments and benchmarks for evaluating hybrid and artificial general intelligence (AGI) systems. This symposium revealed what was already suspected: research concerning evaluation of machine learning/symbolic hybrids and AGI is, unfortunately, lacking. Even so, the discussion was fruitful.

In this paper I discuss critically Richard Swinburne’s concept of God, which I find to be incoherent, and his understanding of Christianity, which I find to be based on a precritical use of the New Testament.

"Who or what is God?," asks John Hick. A theist might answer: God is an infinite person, or at least an infinite personal being. Hick disagrees: "God cannot be both a person and infinite." Moreover, he says, the distinction between being a person and being a personal being "is a distinction without a difference." Thus, God cannot be an infinite personal being either. In this essay, I assess Hick's reasons for drawing these conclusions. I argue that, (...) even if some other reasons for drawing these conclusions are compelling, Hick's reasons are not. (shrink)

Both Wilfrid Sellars and John McDowell reject Kant’s conclusion that the world is fundamentally unknowable, and on similar grounds: each invokes conceptual change, what I call the diachronic instability of a conceptual scheme. The similarities end there, though. It is important to Sellars that the world is only knowable at “the end of inquiry” – he rejects a commonsense realism like McDowell’s for its inability to fully appreciate diachronic instability. To evaluate this disagreement, I consider Timothy Williamson’s argument that (...) the knowability thesis, as it rules out “elusive objects”, is problematically idealistic. I argue that McDowell’s insistence on diachronic instability suffices to address Williamson’s worry, and as such that his reply ought to be available to Sellars too. That Sellars would instead invoke the end of inquiry suggests it is he who underestimates the ineliminability of conceptual change. (shrink)

This paper considers the obligation higher income countries have to lower and middle income countries during a global pandemic. Further considers which reforms are needed to the global supply-chain of medical resources. The short-comings in distribution and medical infrastructure have exacerbated the health crisis in developing countries. Global justice demands radical redistribution of medical resources in order to prevent mass casualties. This is argued first by highlighting that the COVID-19 pandemic should be acknowledged as an issue of global justice, secondly, (...) higher income countries ought to account for distribution inequity as a matter of rectifying past injustices, and thirdly argue for reform in distribution while considering the vaccine rollout as a prime example. We aim to show how the differences from country to country in response capabilities are a result of the economic foundation colonialism established and a direct result of cyclical poverty, which wealthy countries perpetuate to this day.

I summarize John Hick’s pluralistic theory of the world’s great religions, largely in his own voice. I then focus on the core posit of his theory, what he calls “the Real,” but which I less tendentiously call “Godhick”. Godhick is supposed to be the ultimate religious reality. As such, it must be both possible and capable of explanatory and religious significance. Unfortunately, Godhick is, by definition, transcategorial, i.e. necessarily, for any creaturely conceivable substantial property F, it is neither (...) an F nor a non-F. As a result, Godhick is impossible, as shown by the Self-Identity Problem, the Number Problem, and the Pairing Problem. Moreover, even if Godhick is possible, it faces the Insignificance Problem. The upshot is that, so far as I can see, John Hick’s God is unworthy of any further interest. (shrink)

A descriptive polytheist thinks there are at least two gods. John Hick and Richard Swinburne are descriptive polytheists. In this respect, they are like Thomas Aquinas and many other theists. What sets Swinburne and Hick apart from Aquinas, however, is that unlike him they are normative polytheists. That is, Swinburne and Hick think that it is right that we, or at least some of us, worship more than one god. However, the evidence available to me shows (...) that only Swinburne, and not Hick, is a cultic polytheist: he actually worships more than one god. I conclude that only Swinburne is a polytheist par excellence. (shrink)

The author seeks to make the fewest changes that would allow Christianity to withstand the challenges of the problem of evil . The project includes a critical review of the theodicies of John Hick and David Griffin, and also draws upon the thought of Sri Aurobindo. ;From Augustinian thought, the author retains the emphasis upon moral evil. He argues that any theodicy resolving moral evil also resolves natural evil, and that natural evil, as such, would not create major (...) barriers to religious faith. ;The author accepts John Hick's ideas of epistemic distance and soul-making, with supplementation. But he rejects Hick's use of the Greater Good Defense, instead positing that evil cannot be justified. The only question is whether it can be healed. ;David Griffin's strategy of adjusting divine traits to solve the POE is rejected. Instead, the author modifies Christian ideas of human identity and human destiny. Griffin's definition of evil is also rejected. Instead, the author defines evil as "a horrendous violation of an important human value." ;The author posits that Aurobindo correctly identified the Christian doctrine of "one lifetime only" as posing major problems for theodicy. The Indian view of multiple lifetimes helps to resolve dysteleological evil. Karma does not solve the POE all by itself, the author holds, but a revised notion of karma as "a law of appropriate experience" can make an essential contribution. The Indian view of human identity in terms of Self and ego personality is also adopted, again with some modification. ;The author uses an analogy of evil with a wound to argue that all evil can be healed, and must be healed in the process of psycho-spiritual growth. The conclusion is that evil may be ultimate to the ego personality, but is not ultimate to the soul, as such. From the perspective of the Soul or Self, suffering can be self-chosen for important and positive reasons. ;In short, a total picture of human identity and destiny gained by borrowing and revising Indian doctrines enables the author to suggest a new format for the interpretation of evil.

My dissertation combines philosophy of science and political philosophy. Drawing directly on the work of Alasdair MacIntyre and inspired by John Dewey, I develop two rival conceptions of scientific practice. I show that these rivals are closely linked to the two basic sides in the science and values debate -- the debate over the extent to which ethical and political values may legitimately influence scientific inquiry. Finally, I start to develop an account of justice that is sensitive to these (...) legitimate and illegitimate influences. (shrink)

An Editorial for issue 128.1 of the Expository Times.

This chapter explores the interrelation of religious pluralism and eschatology in the thought of John Hick and brings him into dialogue with the nineteenth-century Hindu mystic Sri Ramakrishna. According to Hick’s mature position, various world religions are equally capable of leading to salvation, since all the various religious conceptions of ultimate reality are different culturally conditioned ways of conceiving one and the same unknowable “Real an sich.” The contemporary Christian theologian S. Mark Heim convincingly argues that (...) class='Hi'>Hick’s theory of religious pluralism is less pluralistic than it appears, since Hick conceives the final postmortem state of salvation in vague and monolithic terms, thereby failing to honor the variety of specific religious fulfillments taught by the world religions. Building on Heim’s critique of Hick, I make the case that Ramakrishna’s experientially grounded theory of religious pluralism has significant philosophical advantages over Hick’s theory, since Ramakrishna accepts the equal reality and value of both theistic and non-theistic forms of salvation. According to Ramakrishna’s expansive eschatology, some souls choose to “eat sugar” by remaining in eternal loving communion with the personal God, while other souls prefer to “become sugar” by merging their individuality in the impersonal Absolute.

Iffication, Preiffication, Qualiffication, Reiffication, and Deiffication. -/- Roughly, iffication is the speech-act in which—by appending a suitable if-clause—the speaker qualifies a previous statement. The clause following if is called the qualiffication. In many cases, the intention is to retract part of the previous statement—called the preiffication. I can retract part of “I will buy three” by appending “if I have money”. This initial study focuses on logical relations among propositional contents of speech-acts—not their full conversational implicatures, which will be treated (...) elsewhere. The modified statement—called the iffication—is never stronger than the preiffication. A degenerate iffication is one logically equivalent to its preiffication. There are limiting cases of degenerate iffications. In one, the qualiffication is tautological, as “I will buy three if three is three”. In another, the negation of the qualiffication implies the preiffication, as “I will buy three if I will not buy three”. Reiffication is iffication of an iffication. “I will buy three if I have money” is reifficated by appending “if there are three left”. Deiffication is the speech-act in which—by appending a suitable and-clause—the effect of an iffication is cancelled so that the result implies the preiffication. “I will buy three if I have money” is deifficated by appending “and I have money”. All further examples come from standard (one-sorted, tenseless, non-modal) first-order arithmetic. All theorems are about first-order arithmetic propositions. An easy theorem, hinted above, is that an iffication is degenerate if and only if the negation of the qualiffication implies the preiffication. The iffication of a conjunction using one of the conjuncts as qualiffication need not imply the other conjunct: “Two is an even square if two is square” does not imply “Two is even”.

John Hick's God or Reality centered religious philosophy was claimed by him to be a Copernican revolution in epistemology of God. Is it really so? This article investigates.

This article considers the traditional Islamic narrative in the light of the theory of religion espoused by John Hick (1922–2012). We see how the Islamic narrative changes on a Hickean understanding of religion, particularly in the light of the ‘bottom-up’ approach and trans-personal conception of the religious ultimate that it espouses. Where the two readings of Islam appear to conflict, I suggest how they can be reconciled. I argue that if Hick’s theory is incompatible with Islamic belief, (...) then this incompatibility does not manifest itself at the level of belief in the narrative. (shrink)

John Hick’s theory concerning plurality of religions is an ontologic pluralism according to which all religions are authentic ways for man to attain the "real an sich". Gods of religions are real as perceived and veridical hallucinations; while the “real an sich” has ineffable substantial and trans-categorical properties. Hick’s view suffers from several problems. As a second order analysis of religions, Hick’s view is not a correct one. To reject naturalism, it falls into an epistemological circle, (...) where distinction between formal and substantial properties fades away. It seems that Hick is captured by a category mistake in the presentation of his own theory concerning authenticity of all religions to attain the "real an sich". (shrink)

Religious pluralism is the view that more than one religion is correct, and that no religion enjoys a special status in relation to the ultimate. Yet the world religions appear to be incompatible. How, then, can more than one be correct? Discussions and critiques of religious pluralism usually focus on the work of John Hick, yet there are a number of other pluralists whose responses to this incompatibility problem are importantly different from Hick’s. This article surveys the (...) solutions of Hick, Harrison, Heim, Byrne, and Knitter to the incompatibility problem. I conclude that, while none of these views is without weakness, there are several promising pluralist solutions to this problem. Moreover, confessionalists (i.e. exclusivists and inclusivists) must also address issues related to incompatibility. (shrink)

Religious disagreement – the existence of inconsistent religious views – is familiar and widespread. Among the most fundamental issues of such disagreement is whether to characterise the divine as personal or non-personal. On most other religious issues, the diverse views seem to presuppose some view on the personal/non-personal issue. In this essay, I address a particular question arising from disagreement over this issue. Let an exclusivist belief be a belief that a doctrine d on an issue is true, and that (...) doctrines on the issue that differ from d are false. Assume that for at least some people, there is no epistemic reason to prefer any one exclusivist view on the personal/non-personal question. This might be because disagreements act as defeaters for disputants’ beliefs, or because someone comes at the question without already holding a belief on the matter, and finds each view equally plausible. In these circumstances, is it still possible to engage with particular traditions in a realist, truth-seeking way? I answer that it is, arguing for a new pluralist approach to the personal/non-personal issue. By ‘pluralist’, I mean an approach that reinterprets a doctrine d on a given issue to be consistent with doctrines on the issue that differ from d. I start with probably the best-known pluralist account of religion, that of John Hick. After presenting his account I identify a problem that it faces which any pluralist account must address, one that has clear relevance to the personal/non-personal question. I then draw on Thomas Merton to outline an alternative pluralist route, illustrating how such an approach can apply to Christian and Buddhist ideas of an ultimate spiritual goal. The personal/non-personal issue is a good test for the approach I develop: because of the issue’s fundamentality, if the approach succeeds here then the prospects look bright for applying it to other topics of religious disagreement.

Debate over the adequacy of John Hick's conception of religious pluralism is engaged in a comparative manner.

This article argues (against John Hick and Huston Smith) that different religions teach truths that are different even at the most fundamental level. Nevertheless these are genuine axiological truth claims that can be subject to rational evaluation, differentiating well-founded interpretations of a given religion from interpretations that are not well-founded.

Religious diversity is a key topic in contemporary philosophy of religion. One way religious diversity has been of interest to philosophers is in the epistemological questions it gives rise to. In other words, religious diversity has been seen to pose a challenge for religious belief. In this study four approaches to dealing with this challenge are discussed. These approaches correspond to four well-known philosophers of religion, namely, Richard Swinburne, Alvin Plantinga, William Alston, and John Hick. The study is (...) concluded by suggesting four factors which shape one’s response to the challenge religious diversity poses to religious belief. (shrink)

I argue that John Hick’s soul-making theodicy is committed to opposing social progress. By focusing on justifying the current amount and distribution of suffering and evil, Hick’s theodicy ends up having to condemn even positive change as undesirable. First, I give a brief outline of Hick’s theodicy, with a particular emphasis on the role of earned virtue in justifying the existence of evil. Then I consider two understandings of social progress: progress as the elimination of suffering (...) and evil; and progress as the promotion of earned virtue. I further distinguish the earned virtue understanding of social progress into two kinds, in which the relationship between social structures and moral growth either: allows members of a more advanced society to start closer to perfection; or allows members of a more advanced society to progress more quickly. I argue that no matter which approach we take, Hick’s theodicy struggles with the idea of social progress. Hick is either straightforwardly committed to opposing social progress, or he can support it only at the expense of being unable to justify status quo of suffering and evil. (shrink)

Saying that x is ineffable seems to be paradoxical – either I cannot say anything about x, not even that it is ineffable – or I can say that it is ineffable, but then I can say something and it is not ineffable. In this article, I discuss Alston’s version of the paradox and a solution proposed by Hick which employs the concept of formal and substantial predicates. I reject Hick’s proposal and develop a different account based on (...) some passages from Pseudo-Dionysius’ Mystica Theologia. ‘God is ineffable’ is a metalinguistic statement concerning propositions about God: not all propositions about God are expressible in a human language.

In the last 70 years there has been an explosion of philosophical and theological work on the nature of virtue and the process of virtue formation. Yet philosophers and theologians have paid little attention to the phenomenon of temptation and its role in developing virtue. Indeed, little analytic work has been done on the nature of temptation. This study aims to fill this gap in moral philosophy and theology by offering an analytic moral conception of temptation and explicating its connection (...) to the development of virtue. This project deploys a new iteration of an older methodology of integrating philosophy and theology that may now appropriately be called “analytic moral theology.” In discerning the nature of temptation and its role in virtue formation, theological sources provide foundational guidance. Analytic moral philosophy provides illumination, coherence, and conceptual robustness to the theological foundation. The argument developed follows in the footsteps of John Hick’s soul-making theodicy by contending that the development of virtue requires a world that permits of experiences of temptation. This conclusion is substantiated by a close moral analysis of the nature of temptation that builds on key works done in philosophical moral psychology, philosophy of action, and philosophical theology. The emerging conceptualization of temptation is then compared and contrasted with the closely related moral phenomenon of akrasia and weakness of will, and finally interfaced with a neo- Aristotelian conception of virtue development. In the end, Thomas Aquinas’s understanding of infused virtue is employed as a theological test of the thesis and conditions the scope of the thesis. In light of this constructive analysis of the nature of temptation and its argument for temptation’s role in acquiring moral virtue, this project makes a contribution to philosophical Christian ethics.

In this essay I will show that the incoherence many commentators have found in Kant’s Religion is due to Augustinian assumptions about human evil that they are implicitly reading into the text. Eliminate the assumptions, and the inconsistencies evaporate: both theses, those of universality and moral responsibility, can be held together without contradiction. The Augustinian view must be replaced with what John Hick has dubbed an “Irenaean” account of human evil, which portrays the human being and his or (...) her task in developmental terms. This developmental model is put forward by Kant in both the Lectures in the Philosophy of Religion and in his Conjectural Beginnings of Human History. In this essay I discuss both the Augustinian and Iranaean accounts of human evil, and argue for the advantages of the developmental (Iranaean) account in making philosophical sense of Kant’s texts. I show that Kant indeed held such a view in both the Lectures and in the Conjectural Beginnings, and that he never abandoned the developmental model in Religion. Reading Kant’s Religion through an “Iranaean” lens reframes the locus of the debate, illumines multiple elements of the text that previously remained obscure, and demonstrates why Kant had good reason to claim that we all begin in a condition of radical evil but must nevertheless assume responsibility for this.

This essay develops standards for grading religions including various forms of spiritualism. First, I examine the standards proposed by William James, John Hick, Paul Knitter, Dan Cohn-Sherbok, and Harold Netland. Most of them are useful in grading religions with or without conditions. However, those standards are not enough for refined and piercing evaluation. Thus, I introduce standards used in spiritualism. Although those standards are for grading spirits and their teachings, they are useful in refined and piercing evaluation of (...) religious phenomena. The spiritual standards complement James's, Hick's, Knitter's, and Netland's standards. Although most of the spiritual standards are rationally unjustifiable, they have practical value. (shrink)

This paper examines the nature of religion. A definition of religion is proposed, and a major rival interpretation -- that of John Hick -- is examined and rejected. It is then explained how religions can be evaluated.

This article argues that contemporary philosophers have unduly ignored Sri Ramakrishna’s pioneering views on religious pluralism. The Bengali mystic Sri Ramakrishna (1836-1886) taught the harmony of all religions on the basis of his own spiritual experiences and his diverse religious practices, both Hindu and non-Hindu. Part I reconstructs the main tenets of Sri Ramakrishna’s model of religious pluralism. Part II explores how Sri Ramakrishna addresses the problem of conflicting religious truth-claims. Part III addresses some of the major criticisms leveled against (...) Sri Ramakrishna’s views on religious pluralism. (shrink)

A number of traditional philosophers and religious thinkers advocated an ineffability thesis to the effect that the ultimate reality cannot be expressed as it truly is by human concepts and words. However, if X is ineffable, the question arises as to how words can be used to gesture toward it. We can't even say that X is unsayable, because in doing so, we would have made it sayable. In this article, I examine the solution offered by the fifth-century Indian grammarian-philosopher (...) Bhartrhari and develop it into a linguistic strategy based on the imposition-cum-negation method. The purpose is to show how we can non-contradictorily say, or rather indicate, the unsayable.

Panmetaphoricism is the view that our speech about God can only be metaphorical. In this essay, I do not assess the reasons that have been given for the view. Rather, I assess the view itself. My aim is to develop the most plausible version of panmetaphoricism in order to gain a clear view of the God it offers for our consideration.

A brief reference article on cultural relativism.

In a single-iteration fake barn case, the agent correctly identifies an object of interest on the first try, despite the presence of nearby lookalikes that could have mislead her. In a multiple-iteration fake barn case, the agent first encounters several fakes, misidentifies each of them, and then encounters and correctly identifies a genuine item of interest. Prior work has established that people tend to attribute knowledge in single-iteration fake barn cases, but multiple-iteration cases have not been tested. However, some theorists (...) contend that multiple-iteration cases are more important and will elicit a strong tendency to deny knowledge. Here I report a behavioural experiment investigating knowledge judgments in multiple-iteration fake barn cases. The main finding is that people tend to attribute knowledge in these cases too. Ironically, the results indicate that the presence of fakes could prevent iterated errors from lowering knowledge attributions. The results also provide evidence that ordinary knowledge attributions are based on attributions of cognitive ability. (shrink)

Almost everyone believes that testimony can transmit knowledge from speaker to hearer. What some philosophers mean by this is ordinary and pedestrian-- they mean only that, in at least some cases, a speaker S knows that p, S testifies that p to a hearer H, and H comes to know that p as a result of believing S's testimony. There is disagreement about how this occurs, but that it does occur is sufficient for the transmission of knowledge in the intended (...) sense. On this understanding of transmission, the natural questions are these: (1) What conditions, in addition to speaker knowledge and speaker testimony, are sufficient for the hearer to gain testimonial knowledge?; and (2) Is speaker knowledge always necessary for testimonial knowledge? That is: Is all testimonial knowledge transmitted knowledge? (shrink)

Accounts of ability in the philosophical literature have tended to be modal ones: claims about an agent’s abilities are understood in terms of what she does in certain non-actual scenarios. In contrast, a prominent account of ability ascriptions in the recent semantics literature appeals to genericity: claims about an agent’s abilities are understood in terms of what she generally manages to do. The latter account resolves some long-standing problems for modal accounts, but encounters problems of its own. I propose a (...) hybrid view, on which ability involves both a modal and a generic element. (shrink)

In “Perceptual Confidence,” I argue that our perceptual experiences assign degrees of confidence. In “Precision, not Confidence, Describes the Uncertainty of Perceptual Experience,” Rachel Denison disagrees. In this reply I first clarify what i mean by ‘perceptual experiences’, ‘assign’ and ‘confidence’. I then argue, contra Denison, that perception involves automatic categorization, and that there is an intrinsic difference between a blurry perception of a sharp image and a sharp perception of a blurry image. -/- .

Compatibilism is the view that moral responsibility is compatible with determinism. Natural compatibilism is the view that in ordinary social cognition, people are compatibilists. Researchers have recently debated whether natural compatibilism is true. This paper presents six experiments (N = 909) that advance this debate. The results provide the best evidence to date for natural compatibilism, avoiding the main methodological problems faced by previous work supporting the view. In response to simple scenarios about familiar activities, people judged that agents had (...) moral responsibilities to perform actions that they were unable to perform (Experiment 1), were morally responsible for unavoidable outcomes (Experiment 2), were to blame for unavoidable outcomes (Experiments 3-4), deserved blame for unavoidable outcomes (Experiment 5), and should suffer consequences for unavoidable outcomes (Experiment 6). These findings advance our understanding of moral psychology and philosophical debates that depend partly on patterns in commonsense morality. (shrink)

Recent work has shown that knowledge attributions affect how people think others should behave, more so than belief attributions do. This paper reports two experiments providing evidence that knowledge attributions also affect behavioral predictions more strongly than belief attributions do, and knowledge attributions facilitate faster behavioral predictions than belief attributions do. Thus, knowledge attributions play multiple critical roles in social cognition, guiding judgments about how people should and will behave.

[Edited from Conclusion section:] We have looked at various challenging issues to do with getting connectionism to cope with high-level cognitive activities such a reasoning and natural language understanding. The issues are to do with various facets of generalization that are not commonly noted. We have been concerned in particular with the special forms these issues take in the arena of propositional attitude processing. The main problems we have looked at are: (1) The need to construct explicit representations of generalizations, (...) not just generalize correctly to individual cases; (2) The need to be able to match two or more complex short-term information structures, to enable rapid generalization from recent examples rather than from long-term memories; (3) The need to represent and reason with anomalous combinations of concepts; (4) The need to perform embedded reasoning. This presents special problems for systems using non-concatenative representations (as in mainstream connectionist approaches). We also touched on vague quantification in attitude report complements. Neither this topic nor that of analogies between short-term structures (point 2) has been adequately addressed in the symbolic framework, let alone in connectionism. -/- The opportunities and problems covered are put forward as things worth being optimistic about or pessimistic about, respectively. They are not put forward as decisive arguments for or against connectionism. The hope is that this chapter contributes to a greater understanding of the connectionist/symbolist gap by presenting some unusual issues and by throwing new light on some well known ones. (shrink)

Visualizing and mental imagery are thought to be cognitive states by all sides of the imagery debate. Yet the phenomenology of those states has distinctly visual ingredients. This has potential consequences for the hypothesis that vision is cognitively impenetrable, the ability of visual processes to ground perceptual warrant and justification, and the distinction between cognitive and perceptual phenomenology. I explore those consequences by describing two forms of visual ambiguity that involve visualizing: the ability to visually experience a picture surface as (...) flat after it has caused volumetric nonconceptual contents, and the ability to use a surface initially perceived as flat to visualize three-dimensional scenes. In both cases, the visual processes which extract viewer-centered volumetric shapes have to rely solely on monocular depth cues in the absence of parallax and stereopsis. Those processes can be cognitively penetrated by acts of visualizing, including ones that draw on conceptual information about kinds. However, the penetrability of the visual processes does not weaken their ability to provide perceptual warrant and justification for beliefs. The reason is that picture perceptions—whether they are stimulus -driven or based on acts of visualizing—are different to object perceptions both phenomenologically and in terms of their functional roles as states. Thus, although the penetrability of the visual processes does mean that subjects can have visual experiences with contradictory contents, perceptual belief is adopted at most towards one set of contents, and questions of warrant and justification are raised only for those contents. A rule-proving exception is provided by trompe-l’oeils. (shrink)

Recent work has assumed that the normativity associated with assertion differs from the normativity of morality, practical rationality, etiquette, and legality. That is, whether an assertion “should” be made is not merely a function of these other familiar sorts of normativity and is especially connected to truth. Some researchers have challenged this assumption of distinctive normativity. In this paper I report two experiments that test the assumption. Participants read a brief story, judged whether an assertion should be made, and rated (...) several other qualities of the assertion, including its truth value, morality, rationality, etiquette, legality, and folly. Of these qualities, truth value most strongly predicted assertability. The findings support the assumption of distinctive normativity and provide further evidence that the norm of our social practice of assertion is factive. (shrink)

Synthetic organisms are at the same time organisms and artifacts. In this paper we aim to determine whether such entities have a good of their own, and so are candidates for being directly morally considerable. We argue that the good of non-sentient organisms is grounded in an etiological account of teleology, on which non-sentient organisms can come to be teleologically organized on the basis of their natural selection etiology. After defending this account of teleology, we argue that there are no (...) grounds for excluding synthetic organisms from having a good also grounded in their teleological organization. However, this comes at a cost; traditional artifacts will also be seen as having a good of their own. We defend this as the best solution to the puzzle about what to say about the good of synthetic organisms. (shrink)

The A-theory and the B-theory advance competing claims about how time is grounded. The A-theory says that A-facts are more fundamental in grounding time than are B-facts, and the B-theory says the reverse. We argue that whichever theory is true of the actual world is also true of all possible worlds containing time. We do this by arguing that time is uniquely groundable: however time is actually grounded, it is necessarily grounded in that way. It follows that if either the (...) A-theory or the B-theory is actually false, then it is necessarily false. (shrink)

Two options are incommensurate in value if neither is better than the other, and if a small improvement or worsening of one does not necessarily make it determinately better or worse than the other. If a person faces a sequence of choices between incommensurate options, she may end up with a worse options than she could have had, even though none of her choices are irrational. Yet it seems that rationality should save her from this bad outcome. This is the (...) practical problem posed by incommensurability of values, and it may be solved by a new account of practical reasoning. (shrink)

Our environmental wrongdoings result in a moral debt that requires restitution. One component of restitution is reparative and another is remediative. The remediative component requires that we remediate our characters in ways that alter or eliminate the character traits that tend to lead, in their expression, to environmental wrongdoing. Restitutive restoration is a way of engaging in ecological restoration that helps to meet the remediative requirement that accompanies environmental wrongdoing. This account of restoration provides a new motivation and justification for (...) engaging in restorative practices in addition to the standard pragmatist justification and motivations. (shrink)

A philosopher once wrote the following words:If I examine the PTOLOMAIC and COPERNICAN systems, I endeavour only, by my enquiries, to know the real situation of the planets; that is, in other words, I endeavour to give them, in my conception, the same relations, that they bear towards each other in the heavens. To this operation of the mind, therefore, there seems to be always a real, though often an unknown standard, in the nature of things; nor is truth or (...) falsehood variable by the various apprehensions of mankind. Though all human race should for ever conclude, that the sun moves, and the earth remains at rest, the sun stirs not an inch from his place for all these reasonings; and such conclusions are eternally false and erroneous.

I start with a brief assessment of the implications of Sterelny’s anti-individualist, anti-internalist apprentice learning model for a more historical and interdisciplinary cognitive science. In a selective response I then focus on two core features of his constructive account: collaboration and skill. While affirming the centrality of joint action and decision making, I raise some concerns about the fragility of the conditions under which collaborative cognition brings benefits. I then assess Sterelny’s view of skill acquisition and performance, which runs counter (...) to dominant theories that stress the automaticity of skill. I suggest that it may still overestimate the need for and ability of experts to decompose and represent the elements of their own practical knowledge. (shrink)
