Semantic externalism Are the meanings of natural kind words, such as “water” or “tiger,” in the head or in the world? This question is pressing and controversial in contemporary philosophy. The nature of the meaning related to propositional contents and words of the natural kind raises a fundamental disagreement between two groups of philosophers: defenders of internalism and defenders of externalism. The two groups differ on how to define meaning. Internalists say that meaning is determined entirely by aspects that are (...) internal to the speaker, and mental contents are semantic contents that are in our minds or heads, their slogan is “Meanings are in the head or brain.” Externalists say that meaning is determined, at least in part, by aspects that are external to the speaker, and that contents are linguistic signs and exist in the outside world, and their slogan is “Meanings do not exist only in the head.” In this article, I want to shed explanatory light on this disagreement by examining its origins, explaining some of the arguments in support of externalism, and demonstrating the impact of this disagreement on understanding the nature of meaning. This article addresses several topics: 1. Various types of externalism 2. Description theory and causal theory 3. Hillary Betnam and Twin Earth thought experiment 4. Tyler Berg and arthritis argument 5. Donald Davidson and perceptual externalism 6. Andy Clark and David Chalmers: active externalism -/- هل معانى ألفاظ النوع الطبيعى، مثل "ماء" أو "نمر"، فى الرأس أم فى العالم؟ هذا السؤال ملح ومثير للجدل فى الفلسفة المعاصرة. فطبيعة المعنى المتعلق بالمضامين القضوية وألفاظ النوع الطبيعى يثير خلافًا أساسيًّا بين فريقين من الفلاسفة هم أصحاب النزعة الداخلية internalism وأصحاب النزعة الخارجية externalism. ويختلف الفريقان على كيفية تحديد المعنى. يقول الداخليون إن المعنى يتحدد كلية عن طريق جوانب تكون داخلية للمتكلم، والمضامين العقلية هى مضامين دلالية تكون فى عقولنا أو رؤوسنا، وشعارهم هو "المعانى توجد في الرأس أو المخ". ويقول الخارجيون إن المعنى يتحدد فى جانب منه على الأقل عن طريق جوانب تكون خارجية للمتكلم، والمضامين هى إشارات لغوية وتوجد فى العالم الخارجى، وشعارهم هو "المعانى لا توجد فى الرأس فقط". وأريد فى هذه المقالة أن ألقى ضوءًا شارحًا على هذا الخلاف، وذلك من خلال النظر فى أصوله، وشرح بعض الحجج المؤيدة للنزعة الخارجية، وبيان أثر هذا الخلاف فى فهم طبيعة المعنى. وتعالج هذه المقالة عدة موضوعات هي: 1- صور منوعة من النزعة الخارجية 2- نظرية الوصف والنظرية السببية 3- هيلارى بتنام وتجربة فكر الأرض التوأم 4- تايلر بيرج وحجة التهاب المفاصل .

[This is an edited version of a keynote talk at the conference on Neural Information Processing Systems (NeurIPS) on November 28, 2022, with some minor additions and subtractions.] -/- There has recently been widespread discussion of whether large language models might be sentient or conscious. Should we take this idea seriously? I will break down the strongest reasons for and against. Given mainstream assumptions in the science of consciousness, there are significant obstacles to consciousness in current models: for example, their (...) lack of recurrent processing, a global workspace, and unified agency. At the same time, it is quite possible that these obstacles will be overcome in the next decade or so. I conclude that while it is somewhat unlikely that current large language models are conscious, we should take seriously the possibility that successors to large language models may be conscious in the not-too-distant future.

Inspired by Rudolf Carnap's Der Logische Aufbau Der Welt, David J. Chalmers argues that the world can be constructed from a few basic elements. He develops a scrutability thesis saying that all truths about the world can be derived from basic truths and ideal reasoning. This thesis leads to many philosophical consequences: a broadly Fregean approach to meaning, an internalist approach to the contents of thought, and a reply to W. V. Quine's arguments against the analytic and the a (...) priori. Chalmers also uses scrutability to analyze the unity of science, to defend a conceptual approach to metaphysics, and to mount a structuralist response to skepticism. Based on the 2010 John Locke lectures, Constructing the World opens up debate on central philosophical issues involving language, consciousness, knowledge, and reality. This major work by a leading philosopher will appeal to philosophers in all areas. This entry contains uncorrected proofs of front matter, chapter 1, and first excursus. (shrink)

Does consciousness collapse the quantum wave function? This idea was taken seriously by John von Neumann and Eugene Wigner but is now widely dismissed. We develop the idea by combining a mathematical theory of consciousness (integrated information theory) with an account of quantum collapse dynamics (continuous spontaneous localization). Simple versions of the theory are falsified by the quantum Zeno effect, but more complex versions remain compatible with empirical evidence. In principle, versions of the theory can be tested by experiments with (...) quantum computers. The upshot is not that consciousness-collapse interpretations are clearly correct, but that there is a research program here worth exploring. (shrink)

Cartesian arguments for global skepticism about the external world start from the premise that we cannot know that we are not in a Cartesian scenario such as an evil-demon scenario, and infer that because most of our empirical beliefs are false in such a scenario, these beliefs do not constitute knowledge. Veridicalist responses to global skepticism respond that arguments fail because in Cartesian scenarios, many or most of our empirical beliefs are true. Some veridicalist responses have been motivated using verificationism, (...) externalism, and coherentism. I argue that a more powerful veridicalist response to global skepticism can be motivated by structuralism, on which physical entities are understood as those that play a certain structural role. I develop the structuralist response and address objections. (shrink)

There are two versions of the language-of-thought hypothesis (LOT): Representational LOT (roughly, structured representation), introduced by Ockham, and computational LOT (roughly, symbolic computation) introduced by Fodor. Like many others, I oppose the latter but not the former. Quilty-Dunn et al. defend representational LOT, but they do not defend the strong computational LOT thesis central to the classical-connectionist debate.

Conceptual engineering is the design, implementation, and evaluation of concepts. Conceptual engineering includes or should include de novo conceptual engineering (designing a new concept) as well as conceptual re-engineering (fixing an old concept). It should also include heteronymous (different-word) as well as homonymous (same-word) conceptual engineering. I discuss the importance and the difficulty of these sorts of conceptual engineering in philosophy and elsewhere.

Does the capacity to think require the capacity to sense? A lively debate on this topic runs throughout the history of philosophy and now animates discussions of artificial intelligence. Many have argued that AI systems such as large language models cannot think and understand if they lack sensory grounding. I argue that thought does not require sensory grounding: there can be pure thinkers who can think without any sensory capacities. As a result, the absence of sensory grounding does not entail (...) that large language models cannot think or understand. I also consider to what extent quasi-sensory grounding can at least boost the performance of a language model. (shrink)

What are the philosophical views of contemporary professional philosophers? We surveyed many professional philosophers in order to help determine their views on 30 central philosophical issues. This article documents the results. It also reveals correlations among philosophical views and between these views and factors such as age, gender, and nationality. A factor analysis suggests that an individual's views on these issues factor into a few underlying components that predict much of the variation in those views. The results of a metasurvey (...) also suggest that many of the results of the survey are surprising: philosophers as a whole have quite inaccurate beliefs about the distribution of philosophical views in the profession.

The concept of metaphor as primarily a vehicle for conveying ideas, even if unusual ones, seems to me as wrong as the parent idea that a metaphor has a special meaning. I agree with the view that metaphors cannot be paraphrased, but I think this is not because metaphors say something too novel for literal expression but because there is nothing there to paraphrase. Paraphrase, whether possible or not, inappropriate to what is said: we try, in paraphrase, to say it (...) another way. But if I am right, a metaphor doesn't say anything beyond its literal meaning. This is not, of course, to deny that a metaphor has a point, nor that that point can be brought out by using further words.... My disagreement is with the explanation of how metaphor works its wonders. To anticipate: I depend on the distinction between what words mean and what they are used to do. I think metaphor belongs exclusively to the domain of use. It is something brought off by the imaginative employment of words and sentences and depends entirely on the ordinary meanings of those words and hence on the ordinary meanings of the sentences they comprise. Donald Davidson is University Professor of philosophy at the University of Chicago. He is the author of many important essays, including "Actions, Reasons and Causes," "Causal Relations," and "Truth and Meaning," coauthor of Decision-Making: An Experimental Approach, and coeditor of Words and Objections, Semantics of Natural Language, and The Logic of Grammar.

A familiar interpretation of quantum mechanics (one of a number of views sometimes labeled the "Copenhagen interpretation'"), takes its empirical apparatus at face value, holding that the quantum wave function evolves by the Schrödinger equation except on certain occasions of measurement, when it collapses into a new state according to the Born rule. This interpretation is widely rejected, primarily because it faces the measurement problem: "measurement" is too imprecise for use in a fundamental physical theory. We argue that this is (...) a weak objection, as there may be many ways of making "measurement" precise. However, measurement-collapse interpretations face a more serious objection: a dilemma tied to the quantum Zeno effect. Is measurement itself an observable that can enter superpositions? If yes, then the standard measurement-collapse dynamics is ill-defined. If no, then (at least if measurement is an observable), measurements can never start or finish. The best way out is to deny that measurement is an observable, but this leads to strong and revisionary consequences. This reinforces the view that there is no nonrevisionary interpretation of quantum mechanics. (shrink)

What are the philosophical views of professional philosophers, and how do these views change over time? The 2020 PhilPapers Survey surveyed around 2000 philosophers on 100 philosophical questions. The results provide a snapshot of the state of some central debates in philosophy, reveal correlations and demographic effects involving philosophers' views, and reveal some changes in philosophers' views over the last decade.

This paper offers both a theoretical and an experimental perspective on the relationship between connectionist and Classical (symbol-processing) models. Firstly, a serious flaw in Fodor and Pylyshyn’s argument against connectionism is pointed out: if, in fact, a part of their argument is valid, then it establishes a conclusion quite different from that which they intend, a conclusion which is demonstrably false. The source of this flaw is traced to an underestimation of the differences between localist and distributed representation. It has (...) been claimed that distributed representations cannot support systematic operations, or that if they can, then they will be mere implementations of traditional ideas. This paper presents experimental evidence against this conclusion: distributed representations can be used to support direct structure-sensitive operations, in a man- ner quite unlike the Classical approach. Finally, it is argued that even if Fodor and Pylyshyn’s argument that connectionist models of compositionality must be mere implementations were correct, then this would still not be a serious argument against connectionism as a theory of mind.

Neo-Humean instrumentalists hold that anagent's reasons for acting are grounded in theagent's desires. Numerous objections have beenleveled against this view, but the mostcompelling concerns the problem of ``aliendesires'' – desires with which the agent doesnot identify. The standard version ofneo-Humeanism holds that these desires, likeany others, generate reasons for acting. Avariant of neo-Humeanism that grounds anagent's reasons on her values, rather than allof her desires, avoids this implication, but atthe cost of denying that we have reasons to acton innocent whims. (...) A version of neo-Humeanismthat holds that an agent has reason to satisfyall of her desires that are not in conflictwith her values appears to allow us to grantthe reason-giving force of innocent whims whiledenying the reason-giving force of alien desires.

According to the Weak Supplementation Principle (WSP)—a widely received principle of mereology—an object with a proper part, p , has another distinct proper part that doesn't overlap p . In a recent article in this journal, Nikk Effingham and Jon Robson employ WSP in an objection to endurantism. I defend endurantism in a way that bears on mereology in general. First, I argue that denying WSP can be motivated apart from the truth of endurantism. I then go on to offer (...) an explanation of WSP's initial appeal, argue that denying WSP fails to have untoward consequences for the rest of mereology, and show that the falsity of WSP is consistent with a primary guiding thought behind it.

In this essay it is shown that the imaginative art of scientific theorizing – at its technical best – animates Quine's philosophy as importantly as the more Spartan norms honored in his present pantheon of virtues. By drawing a contrast between the standing of theories in philosophy and theories in science, it will be shown that the speculative reaches of philosophy, along with developments in semantic theory, now oblige an internal revision of Quine's stance against meaning as it was announced (...) in “Two Dogmas of Empiricism.” So, corollary to this proposed revision, I argue that in natural philosophy, the muse of the “art of science” deserves an address along with the more Spartan norms in Quine's present philosophical pantheon. As semantic theory and analyticity thus gain a measure of philosophical tenability, Quine's holism emerges as the more central doctrine of his mature vision. (shrink)

Robbie Williams’ (2020) book The Metaphysics of Representation is the new leading edge of the program of naturalizing intentionality. Williams brings sophistica.

Comparative valuation of different policy interventions often requires interpersonal comparability of benefit. In the field of health economics, the metric commonly used for such comparison, quality adjusted life years (QALYs) gained, has been criticized for failing to respect the equality of all persons’ intrinsic worth, including particularly those with disabilities. A methodology is proposed that interprets ‘full quality of life’ as the best health prospect that is achievable for the particular individual within the relevant budget constraint. This calibration is challenging (...) both conceptually and operationally as it shifts dramatically when technology or budget developments alter what can be achieved for incapacitated individuals. The proposal nevertheless ensures that the maximal achievable satisfaction of one person’s preferences can carry no more intrinsic value than that of another. This approach, which can be applied to other domains of social valuation, thus prevents implicit discrimination against the elderly and those with irremediable incapacities. (shrink)

There is more than one way to say that composition is identity. Yi has distinguished the Weak Composition thesis from the Strong Composition thesis and attributed the former to David Lewis while noting that Lewis associates something like the latter with me. Weak Composition is the thesis that the relation between the parts collectively and their whole is closely analogous to identity. Strong Composition is the thesis that the relation between the parts collectively and their whole is identity. Yi is (...) right that Strong Composition does not fully reflect my view. We must recognize further what, borrowing Lewis's characterization, could be called the "stronger, and stranger" Composition thesis, or what I'll call the Stronger Composition thesis for short. On Strong Composition, it is only collectively that the parts are identical with the whole. On Stronger Composition, they are individually identical with it as well. I will explain and motivate this thesis. (shrink)

Construing the instantiation of a universal by a particular in terms of my theory of aspects resolves the basic mystery of this "non-relational tie", and gives theoretical unity to the four characteristics of instantiation discerned by Armstrong. Taking aspects as distinct in a way akin to Scotus's formal distinction, I suggest that instantiation is the sharing of an aspect by a universal and a particular--a kind of partial identity. This approach allows me to address Plato's multiple location and One over (...) Many problems, Bradley's problem concerning the instantiation of relations, and the problem of change. (shrink)

Composite materialism, as I will understand it, is the view that human persons are composite material objects. This paper develops and investigates an argument, The Vague Singulars Argument, for the falsity of composite materialism. We shall see that cogent or not, the Vague Singulars Argument has philosophically significant ramifications.

Confucius gave counsel that is notoriously hard to follow: "What you do not wish for yourself, do not impose on others" (Huang 1997: 15.24). People tend to be concerned with themselves and to be indifferent to most others. We are distinct from others so our self-concern does not include them, or so it seems. Were we to realize this distinctness is merely apparent--that our true self includes others--Confucius's counsel would be easier to follow. Concern for our true self would extend (...) concern beyond the narrow selves we appear to be. The neo-Confucians held just such a view. They espoused an identity with the universe and everything in it, arguing that this identity explains a natural concern for everyone and everything, not just for our narrow selves. However, many things in the universe differ from each other, that is, some have qualities others lack. If they are all one and the same thing then that one thing differs from itself. I will suggest that the objection can be answered with some metaphysical innovation. I will address the objection by sketching a theory--call it the theory of aspects--that explains how numerically identical things can differ qualitatively. (shrink)

An ironic work, Hume's _Dialogues_ continues to be subject to varying estimates of his reputed hostility to religion. The paper presents the _Dialogues_ as an answer to Minucius.

I argue that an individual has aspects numerically identical with it and each other that nonetheless qualitatively differ from it and each other. This discernibility of identicals does not violate Leibniz's Law, however, which concerns only individuals and is silent about their aspects. They are not in its domain of quantification. To argue that there are aspects I will appeal to the internal conflicts of conscious beings. I do not mean to imply that aspects are confined to such cases, but (...) the best way to start is to recognize them experientially. We can feel the conflicts within ourselves. In doing so we can feel some of our aspects. I will try to enhance our understanding of the concept of aspect by listing and formalizing some principles for its use. After that I will argue that all sorts of individual things have aspects, not just people who are conflicted. (shrink)

In the correspondence with Arnauld, Leibniz contends that each corporeal substance has a substantial form. In support he argues that to be real a corporeal substance must be one and indivisible, a true unity. I will show how this argument precludes a tempting interpretation of corporeal substances as composite unities. Rather it mandates the interpretation that each corporeal substance is a single monad.

This essay interprets Butler’s distinction between identity in the loose and popular sense and in the strict and philosophical sense. Suppose there are different standards for counting the same things. Then what are two distinct things counting strictly may be one and the same thing counting loosely. Within a given standard identity is one-one. But across standards it is many-one. An alternative interpretation using the parts-whole relation fails, because that relation should be understood as many-one identity. Another alternative making identity (...) relative to sort fails, because whole and parts can be of the same sort. (shrink)

Two things become one thing, something having parts, and something becoming something else, are cases of many things being identical with one thing. This apparent contradiction introduces others concerning transitivity of identity, discernibility of identicals, existence, and vague existence. I resolve the contradictions with a theory that identity, number, and existence are relative to standards for counting. What are many on some standard are one and the same on another. The theory gives an account of the discernibility of identicals using (...) phrases like “insofar as”. And it holds that standards for counting remain or shift depending on our purposes. (shrink)

Gauthier's version of the Lockean proviso (in Morals by Agreement) is inappropriate as the foundation for moral rights he takes it to be. This is so for a number of reasons. It lacks any proportionality test thus allowing arbitrarily severe harms to others to prevent trivial harms to oneself. It allows one to inflict any harm on another provided that if one did not do so, someone else would. And, by interpreting the notion of bettering or worsening one's position in (...) terms of subjective expected utility, it allows immoral manipulation of others and imposes unwarranted restrictions based on preferences that should carry no moral weight.

Don Marquis argues that his “future of value” account of the ethics of killing affords us a persuasive argument against abortion that avoids difficult questions about the moral status of the fetus. I argue that Marquis’ account is missing essential detail required for the claimed plausibility of the argument and that any attempt to provide this needed detail can be expected to undercut the claim of plausibility. I argue that this is the case because attempts to provide the missing detail (...) are tantamount to accounts of moral status of the sort Marquis claims to avoid and can therefore be expected to have all the familiar problems of such accounts. Finally, I consider the standard problem infanticide poses for a familiar model of personhood and argue that Marquis’ use of this objection as ablanket criticism of personhood accounts is superficial.

Desde Descartes a epistemologia tem se baseado no conhecimento de primeira pessoa. Devemos começar, de acordo com a história usual, com o que é mais certo: o conhecimento de nossas próprias sensações e pensamentos. De uma maneira ou outra, progredimos então, se pudermos, para o conhecimento de um mundo externo objetivo. Há por fim uma passagem tênue ao conhecimento das outras mentes. Defendo uma total revisão desse quadro. Todo pensamento proposicional, quer positivo ou cético, sobre o interior ou sobre o (...) exterior, exige a posse do conceito de verdade objetiva, e esse conceito está acessível apenas a criaturas que estão em comunicação com outras. O conhecimento de outras mentes é, assim, básico para todo o pensamento. Mas esse conhecimento exige e supõe o conhecimento de um mundo compartilhado de objetos em um espaço e tempo comuns. Assim, a aquisição do conhecimento não é baseada em uma progressão do subjetivo para o objetivo; ele emerge holisticamente e é interpessoal desde o começo. (shrink)

Is a social complex identical to many united people or is it a group entity in addition to the people? For specificity, I will assume that a social complex is a plural subject in Margaret Gilbert’s sense. By appeal to my theory of Aspects, according to which there can be qualitative difference without numerical difference, I give an answer that is a middle way between metaphysical individualism and metaphysical holism. This answer will enable answers to two additional metaphysical questions: (i) (...) how can two social complexes have all the same members and (ii) how can there be a social complex of social complexes?

Contractarians view justice as being defined by a contract made by rational individuals. No one supposes that this contract is actual, and the fact that it is merely hypothetical raises a number of questions both about the assumptions under which it would be actual and about the force of hypothetical agreement that is contingent on these assumptions.Particular contractarian theories must specify the circumstances of the agreement and the endowments, beliefs, desires, and degree and type of rationality of the agents. How (...) these issues are settled determines the force of the hypothetical agreement. The fact that ignorant people who desired only universal suffering would, under duress, agree to a certain principle gives us no reason to believe the principle is a correct moral principle or to think it rational to accept or act on it: some counterfactual assumptions undermine entirely the moral force of hypothetical agreement. On the other hand, to take people just as they are, with their current beliefs, desires, endowments, and all, is to endorse their ignorance and mistakes as well as any previous injustice that affects their bargaining power.

ABSTRACT According to David Lewis, alteration is "qualitative difference between temporal parts of something." It follows that moments, since they are simple and lack temporal parts, cannot alter from future to present to past. Here then is another way to put McTaggart's paradox about change in tense. I will appeal to my theory of Aspects to rebut the thought behind this rendition of McTaggart. On my theory, it is possible that qualitatively differing things be numerically identical. I call these differing, (...) numerically identical things "aspects." I will argue that alteration can be a qualitative difference between temporal aspects of something that lacks temporal parts. So a moment can alter in tense. By rejecting Lewis's assumption my theory can solve this version of McTaggart's paradox. (shrink)

Neo-Humean instrumentalist theories of reasons for acting have been presented with a dilemma: either they are normatively trivial and, hence, inadequate as a normative theory or they covertly commit themselves to a noninstrumentalist normative principle. The claimed result is that no purely instrumentalist theory of reasons for acting can be normatively adequate. This dilemma dissolves when we understand what question neo-Humean instrumentalists are addressing. The dilemma presupposes that neo-Humeans are attempting to address the question of how to act, 'simpliciter'. Instead, (...) they are evaluating actions from the agent's normative perspective.

Pace Perry, wondering whether perceived things are identical is thinking about them, for Hume, with no thought of perceptions of them. Hume is not a proto-Fregean; Hume's Difficulty is not a version of Frege's Puzzle.

Pace Garrett, wondering about the identity of an observed object is wondering whether it is really one or two things, not whether there is one F or (...) two Fs. Second, Humean consciousness is apperception, not immediate awareness. Third, Hume finds nothing with epistemic merit. (shrink)

Acts of violence and murder have historically proved difficult to accommodate in standard accounts of the formula of universal law (FUL) version of Kant’s Categorical Imperative (CI). In “Murder and Mayhem,” Barbara Herman offers a distinctive account of the status of these acts that is intended to be appropriately didactic in comparison to accounts like the practical contradiction model. I argue that while Herman’s account is a promising one, the distinction she makes between coercive and non-coercive violence and her response (...) to concerns with the classification of the latter as imperfect duties raise significant questions about the status of some duties. I suggest that we look, instead, to Kant’s treatment of suicide in The Metaphysics of Morals for an account of norms of non-violence and, in particular, to the connection between this duty and concerns with inner freedom and moral health. I argue that we can use this account to inform our general understanding of duties prohibiting killing and violence, and that the resulting account is a promising one. (shrink)

Benefit/cost analysis is a technique for evaluating programs, procedures, and actions; it is not a moral theory. There is significant controversy over the moral justification of benefit/cost analysis. When a procedure for evaluating social policy is challenged on moral grounds, defenders frequently seek a justification by construing the procedure as the practical embodiment of a correct moral theory. This has the apparent advantage of avoiding difficult empirical questions concerning such matters as the consequences of using the procedure. So, for example, (...) defenders of benefit/cost analysis (BCA) are frequently tempted to argue that this procedurejust isthe calculation of moral Tightness – perhaps that what itmeansfor an action to be morally right is just for it to have the best benefit-to-cost ratio given the accounts of “benefit” and “cost” that BCA employs. They suggest, in defense of BCA, that they have found the moral calculus – Bentham's “unabashed arithmetic of morals.” To defend BCA in this manner is to commit oneself to one member of a family of moral theories (let us call thembenefit/cost moral theoriesorB/C moral theories) and, also, to the view that if a procedure is (so to speak) the direct implementation of a correct moral theory, then it is a justified procedure. Neither of these commitments is desirable, and so the temptation to justify BCA by direct appeal to a B/C moral theory should be resisted; it constitutes an unwarranted short cut to moral foundations – in this case, an unsound foundation. Critics of BCA are quick to point out the flaws of B/C moral theories, and to conclude that these undermine the justification of BCA. But the failure to justify BCA by a direct appeal to B/C moral theory does not show that the technique is unjustified. There is hope for BCA, even if it does not lie with B/C moral theory. (shrink)

How is it possible for David Hume to be both withering skeptic and constructive theorist? I recommend an answer like the Pyrrhonian answer to the question how it is possible to suspend all judgment yet engage in active daily life. Sextus Empiricus distinguishes two kinds of assent: one suspended across the board and one involved with daily living. The first is an act of will based on appreciation of reasons; the second is a causal effect of appearances. Hume makes the (...) same distinction, only he extends the sort of assent involved in daily life to theoretical matters as well. He is a skeptic both in finding no reason to grant the first sort of assent and in being subject to the second. (shrink)

Abstract:I examine the often-denigrated concept of the novel of ideas from its inception and critical decline to its relatively recent revival. Using a variant of the exploitation-exploration dilemma in psychology, I suggest that early usage referred to works that exploit philosophical principles—or better, enact them—by setting philosophical positions in conflict. By contrast, use of the concept for more recent works sees characters and plots exploring philosophical stances. The shift corresponds with the greater attention paid to complexity and ambiguity that are (...) hallmarks of continental philosophy and neopragmatism, and with it greater need to explore philosophical stances through fiction.

There is a familiar problem in moral theories that recognize positive obligations to help others related to the practical room these obligations leave for ordinary life, and the risk that open-ended obligations to help others will consume our lives and resources. Responding to this problem, Kantians have tended to emphasize the idea of limits on positive obligations but are typically unsatisfactorily vague about the nature and extent of these limits. I argue here that aspects of Kant’s discussion of duties of (...) virtue owed to ourselves suggest a useful metric we can use in discussing these limits and that generalizing this account and combining it with elements of Barbara Herman’s view, offers us an attractive model of moral deliberation with the resources we need to engage the critic’s challenge properly.
