To understand the thesis of actualism, consider the following example. Imagine a race of beings — call them ‘Aliens’ — that is very different from any life-form that exists anywhere in the universe; different enough, in fact, that no actually existing thing could have been an Alien, any more than a given gorilla could have been a fruitfly. Now, even though there are no Aliens, it seems intuitively the case that there could have been such things. After all, life might (...) have evolved very differently than the way it did in fact. So in virtue of what is it true that there could have been Aliens when in fact there are none, and when, moreover, nothing that exists in fact could have been an Alien? So-called "possibilists" offer the following answer: ‘It is possible that there are Aliens’ is true because there are in fact individuals that could have been Aliens. At first blush, this might appear directly to contradict the premise that no existing thing could possibly have been an Alien. The possibilist's thesis, however, is that existence, or actuality, encompasses only a subset of the things that, in the broadest sense, are. So for the possibilist, ‘It is possible that there are Aliens’ is true simply in virtue of the fact that there are possible-but-nonactual Aliens, i.e., things that could have existed (but do not) and which would have been Aliens if they had. Actualists reject this answer; they deny that there are any nonactual individuals. Thus, actualism is the philosophical position that everything there is — everything that can in any sense be said to be — exists, or is actual. (shrink)

This paper criticizes the conjunction of two theses: 1) cognitivism about first-person moral ought-beliefs, the thesis (roughly) that such beliefs are attitudes with truth-valued contents; 2) robust internalism about these beliefs, the thesis that, necessarily, agents' beliefs that they ought, morally, to A constitute motivation to A. It is argued that the conjunction of these two theses places our moral agency at serious risk. The argument, which centrally involves attention to clinical depression, is extended to a less demanding, recent brand (...) of internalist moral cognitivism. Philosophers discussed include Dancy, McDowell, McNaughton, and Nagel. (shrink)

1. Presumably the point of, say, inculcating a moral outlook lies in a concern with how people live. It may seem that the very idea of a moral outlook makes room for, and requires, the existence of moral theory, conceived as a discipline which seeks to formulate acceptable principles of conduct. It is then natural to think of ethics as a branch of philosophy related to moral theory, so conceived, rather as the philosophy of science is related to science. On (...) this view, the primary topic of ethics is the concept of right conduct, and the nature and justification of principles of behaviour. If there is a place for an interest in the concept of virtue, it is a secondary place. Virtue is a disposition to behave rightly; the nature of virtue is explained, as it were, from the outside in.

Ordinary English contains different forms of quantification over objects. In addition to the usual singular quantification, as in 'There is an apple on the table', there is plural quantification, as in 'There are some apples on the table'. Ever since Frege, formal logic has favored the two singular quantifiers ∀x and ∃x over their plural counterparts ∀xx and ∃xx (to be read as for any things xx and there are some things xx). But in recent decades it has been argued (...) that we have good reason to admit among our primitive logical notions also the plural quantifiers ∀xx and ∃xx. More controversially, it has been argued that the resulting formal system with plural as well as singular quantification qualifies as ‘pure logic’; in particular, that it is universally applicable, ontologically innocent, and perfectly well understood. In addition to being interesting in its own right, this thesis will, if correct, make plural quantification available as an innocent but extremely powerful tool in metaphysics, philosophy of mathematics, and philosophical logic. For instance, George Boolos has used plural quantification to interpret monadic second-order logic and has argued on this basis that monadic second-order logic qualifies as “pure logic.” Plural quantification has also been used in attempts to defend logicist ideas, to account for set theory, and to eliminate ontological commitments to mathematical objects and complex objects. (shrink)

This paper criticizes George Boolos's famous use of plural quantification to argue that monadic second-order logic is pure logic. I deny that plural quantification qualifies as pure logic and express serious misgivings about its alleged ontological innocence. My argument is based on an examination of what is involved in our understanding of the impredicative plural comprehension schema.

The simplest quantified modal logic combines classical quantification theory with the propositional modal logic K. The models of simple QML relativize predication to possible worlds and treat the quantifier as ranging over a single fixed domain of objects. But this simple QML has features that are objectionable to actualists. By contrast, Kripke-models, with their varying domains and restricted quantifiers, seem to eliminate these features. But in fact, Kripke-models also have features to which actualists object. Though these philosophers have introduced variations (...) on Kripke-models to eliminate their objectionable features, the most well-known variations all have difficulties of their own. The present authors reexamine simple QML and discover that, in addition to having a possibilist interpretation, it has an actualist interpretation as well. By introducing a new sort of existing abstract entity, the contingently nonconcrete, they show that the seeming drawbacks of the simplest QML are not drawbacks at all. Thus, simple QML is independent of certain metaphysical questions. (shrink)

I hear the patter of little feet around the house, I expect Bruce. What I expect is a cat, a particular cat. If I heard such a patter in another house, I might expect a cat but no particular cat. What I expect then seems to be a Meinongian incomplete cat. I expect winter, expect stormy weather, expect to shovel snow, expect fatigue---a season, a phenomenon, an activity, a state. I expect that someday mankind will inhabit at least five planets. (...) This time what I expect is a state of affairs. If we let surface grammar be our guide, the objects of expectation seem quite a miscellany. The same goes for belief, since expectation is one kind of belief. The same goes for desire: I could want Bruce, want a cat but no particular cat, want winter, want stormy weather, want to shovel snow, want fatigue, or want that someday mankind will inhabit at least five planets. The same goes for other attitudes to the extent that they consist partly of beliefs or desires or lacks thereof. But the seeming diversity of objects might be an illusion. Perhaps the objects of attitudes are uniform in category, and it is our ways of speaking elliptically about these uniform objects that are diverse. That indeed is our consensus. We mostly think that the attitudes uniformly have propositions as their objects. That is why we speak habitually of "propositional attitudes.". (shrink)

Content skepticism about practical reason is doubt about the bearing of rational considerations on the activities of deliberation and choice. Motivational skepticism is doubt about the scope of reason as a motive. Some people think that motivational considerations alone provide grounds for skepticism about the project of founding ethics on practical reason. I will argue, against this view, that motivational skepticism must always be based on content skepticism. I will not address the question of whether or not content skepticism is (...) justified. I want only to establish the fact that motivational skepticism has no independent force. (shrink)

The word ‘cosmopolitan’, which derives from the Greek word kosmopolitês (‘citizen of the world’), has been used to describe a wide variety of important views in moral and socio political philosophy. The nebulous core shared by all cosmopolitan views is the idea that all human beings, regardless of their political affiliation, do (or at least can) belong to a single community, and that this community should be cultivated. Different versions of cosmopolitanism envision this community in different ways, some focusing on (...) political institutions, others on moral norms or relationships, and still others focusing on shared markets or forms of cultural expression. The philosophical interest in cosmopolitanism lies in its challenge to commonly recognized attachments to fellow citizens, the local state, parochially shared cultures, and the like. (shrink)

Virtue theorists in ethics often embrace the following characterizationof right action: An action is right iff a virtuous agent would performthat action in like circumstances. Zagzebski offers a parallel virtue-basedaccount of epistemically justified belief. Such proposals are severely flawedbecause virtuous agents in adverse circumstances, or through lack ofknowledge can perform poorly. I propose an alternative virtue-based accountaccording to which an action is right (a belief is justified) for an agentin a given situation iff an unimpaired, fully-informed virtuous observerwould deem the (...) action to be right (the belief to be justified). (shrink)

I argue that recent virtue theories (including those of Hursthouse, Slote, and Swanton) face important initial difficulties in accommodating the supererogatory. In particular, I consider several potential characterizations of the supererogatory modeled upon these familiar virtue theories (and their accounts of rightness) and argue that they fail to provide an adequate account of supererogation. In the second half of the paper I sketch an alternative virtue-based characterization of supererogation, one that is grounded in the attitudes of virtuous ideal observers, and (...) that avoids the concerns raised in the first part of the paper. (shrink)

: In this paper I attempt to defuse a set of epistemic worries commonly raised against ideal observer theories. The worries arise because of the omniscience often attributed to ideal observers – how can we, as finite humans, ever have access to the moral judgements or reactions of omniscient beings? I argue that many of the same concerns arise with respect to other moral theories (and that these concerns do not in fact reveal genuine flaws in any of these theories), (...) and further, that we can and often do have knowledge of the reactions of ideal observers (according to standard, prominent theories in the domain of epistemology). (shrink)

Moral response-dependent metaethical theories characterize moral properties in terms of the reactions of certain classes of individuals. Nick Zangwill has argued that such theories are flawed: they are unable to accommodate the motive of duty. That is, they are unable to provide a suitable reason for anyone to perform morally right actions simply because they are morally right. I argue that Zangwill ignores significant differences between various approvals, and various individuals, and that moral response-dependent theories can accommodate the motive of (...) duty.

Atomism denies that complexes exist. Common-sense metaphysics may posit masses, composite individuals and sets, but atomism says there are only simples. In a singularist logic, it is difficult to make a plausible case for atomism. But we should accept plural logic, and then atomism can paraphrase away apparent reference to complexes. The paraphrases require unfamiliar plural universals, but these are of independent interest; for example, we can identify numbers and sets with plural universals. The atomist paraphrases would fail if plurals (...) presuppose complexes: but an Appendix shows that reference to complexes is not required in the semantics of plurals. (shrink)

SummaryNeither an infant one week old nor a snail is a rational creature. If the infant survives long enough, he will probably become rational, while this is not true of the snail. If we like, we may say of the infant from the start that he is a rational creature because he will probably become rational if he survives, or because he belongs to a species with this capacity. Whichever way we talk, there remains the difference, with respect to rationality, (...) between the infant and the snail on one hand, and the normal adult person on the other; this difference is discussed here.The difference consists, it is argued, in the having of propositional attitudes such as belief, desire, intention and shame. This raises the question how to tell when a creature has propositional attitudes; snails, we may agree, do not, but how about dogs or chimpanzees? The question is not empirical; the question is what sort of empirical evidence is relevant to deciding when a creature has propositional attitudes.It is next contended that language is a necessary concomitant of any of the propositional attitudes. This idea is not new, but there seem to be few arguments in its favor in the literature; one is attempted here.Crucial to the considerations advanced is the idea that belief depends on having the concept of objective truth, and that this comes only with language.RéuméNi un bébé d'une semaine, ni un serpent ne sont des créatures rationnelles. Si le bébé survit assez longtemps, il deviendra probablement rationnel, mais ce n'est pas vrai pour le serpent. Sil'on veut, on peut dire d'emblee du bébé qu'il est une créature rationnelle parce qu'il le deviendra s'il survit ou parce qu'il appartient à une espèce qui possède cette faculté. Quoi qu'on dise, la différence subsiste, en ce qui concerné la rationalité, entre le bébé et le serpent d'une part, la per‐sonne adulte normale de lcar;autre, et c'est cette différence qui sera discutée ici.La différence consiste, selon l'auteur, en une capacityé d'avoir des attitudes propositionnelles telles que la croyance, le désir, l'intention et la honte. Ceci pose la question de savoir quand on peut dire qu'une créature a des attitudes propositionnelles; on peut se mettre d'accord sur le fait que les serpents n'en ont pas, mais qu'en est‐il des chiens et des chimpanzés? La question n'est pas empirique, elle est de savoir quelle donnée empirique va décider si oui ou non une créature a des attitudes propositionnelles.L'auteur prétend que les attitudes propositionnelles s'accompagnent nécessairement du langage. Cette idèe n'est pas nouvelle, mais il semble qu'il y a peu d'arguments qui la soutiennent dans la littérature. On en trouvera un ici, où l'on montre qu'un élément crucial de a croyance dépend de l'acquisition du concept de vérité objective, qui ne se développe qu'avec le langage.ZusammenfassungWeder ein eine Woche altes Kind noch eine Schlange sind rationale Wesen. Wenn das Kind lange genug überlebt, wird es sich wahrscheinlich zu einem vernünftigen Wesen entwickeln, wäh‐rend das für die Schlange nicht zutrifft. Wenn wir wollen, können wir vom Kind sagen, dass es von Anfang an cin rationales Wesen ist, weil es im Fallc des Ubcrlebens vernünftig werden wird oder weil es zu einer Spezies mit dieser Fähigkeit gehört. Wie auch immer wir das ausdrücken, bleibt bezüglich der Rationalität der Unterschied zwischen dem Kind und der Schlange einerseits und der erwachsenen Person andererseits zurück. Dieser Unterschied wird hier diskutiert.Es wird argumentiert, dass der Unterschied in der Fähigkeit besteht, psychologische Haltun‐gen wie Glauben, Begierden, Absichten und Scham zu haben. Damit erhebt sich die Frage, wie man entscheiden kann, wann ein Wesen solchc Einstellungcn hat; Schlangen, wird man zugeben, haben keine; wie steht es aber mit Hunden Oder Schimpansen? Die Frage ist keine empirische, sondern betrifft die Frage, welche Art von empirischen Belegen für den Entscheid relevant ist, ob ein Wesen derartige Einstellungen hat.Es wird die These aufgestellt, dass Sprachen ein notwendiger Begleitumstand einer jeglichen propositionalen Haltung ist. Der Gedanke ist zwar nicht neu, aber es finden sich wenige Argu‐mente zu seiner Stützung in der Literatur; eines wird hier ausgeführt.Entscheidend für die vorgelegten Betrachtungen ist die Auffassung, wonach Glaube vom Begriff der objektiven Wahrheit abhängt, und dieser kommt erst mit der Sprache.

This article discusses the problems which concepts pose for the attribution of thoughts to animals. It locates these problems within a range of other issues concerning animal minds (section 1), and presents a ‘lingualist master argument’ according to which one cannot entertain a thought without possessing its constituent concepts and cannot possess concepts without possessing language (section 2). The first premise is compelling if one accepts the building-block model of concepts as parts of wholes – propositions – and the idea (...) that intentional verbs signify relations between subjects and such propositions. But I shall find fault with both (section 3). This opens the way for recognizing a form of ‘holodoxastic’ thought-ascription which does not presuppose concept-possession on the part of the subject (section 4). Section 5 defends this idea against objections. Section 6 turns to the second premise of the lingualist master argument. I press the idea of judgement into service as a label for conceptual thought that need not be linguistic and argue that the possession of concepts is an ability. Section 7 accepts that concept-possession requires the ability to classify rather than merely to discriminate, but suggests that this need not disqualify animals. In the final section I confirm this verdict by returning to the notion of judgement: classification is the deliberate and considered response to a range of options in a sorting or discrimination task. Notwithstanding appearances to the contrary, the capacity for such a response does not presuppose the linguistic ability to answer questions. Judgement is a feature of a type of problem-solving that we share with some non-linguistic creatures. (shrink)

I argue that recent developments in animal cognition support the conclusion that HOT theory is consistent with animal consciousness. There seems to be growing evidence that many animals are indeed capable of having I-thoughts, including episodic memory, as well as have the ability to understand the mental states of others.

In this paper we defend a version of moral internalism and a cognitivist account of motivation against recent criticisms. The internalist thesis we espouse claims that, if an agent believes she has reason to A, then she is motivated to A. Discussion of counter-examples has been clouded by the absence of a clear account of the nature of motivation. While we can only begin to provide such an account in this paper, we do enough to show that our version of (...) internalism can be defended against putative counter-examples. All theories of motivation which take what motivates to be a psychological state run foul of the following plausible constraint: the reason why you ought to do an action and the reason why you do it can be the same. In our view, however, while what motivates is a reason (which is a fact) the state of being motivated is a cognitive stage, viz. the belief that one has reason to act. In cases where the agent's relevant beliefs are false, then she has no reason to act, but nontheless her action can be explained in other ways. (shrink)

The moral philosophy of the first half of the twentieth century, at least in the English-speaking part of the world, has been largely devoted to problems of an ontological or epistemological nature. This concentration of effort by many acute analytical minds has not produced any general agreement with respect to the solution of these problems; it seems likely, on the contrary, that the wealth of proposed solutions, each making some claim to plausibility, has resulted in greater disagreement than ever before, (...) and in some cases disagreement about issues so fundamental that certain schools of thought now find it unrewarding, if not impossible, to communicate with one another. Moral philosophers of almost all schools seem to agree, however, that no major possibility has been neglected during this period, and that every proposed solution which can be adjudged at all plausible has been examined with considerable thoroughness. It is now common practice, for example, for the authors of books on moral philosophy to introduce their own theories by what purports to be a classification and review of all \emph{possible} solutions to the basic problems of analysis; and in many cases, indeed, the primary defense of the author's own position seems to consist in the negative argument that his own position cannot fail to be correct because none of the others which he has mentioned is satisfactory.

Consider orthodox motivational judgment internalism: necessarily, A’s sincere moral judgment that he or she ought to φ motivates A to φ. Such principles fail because they cannot accommodate the amoralist, or one who renders moral judgments without any corresponding motivation. The orthodox alternative, externalism, posits only contingent relations between moral judgment and motivation. In response I first revive conceptual internalism by offering some modifications on the amoralist case to show that certain community-wide motivational failures are not conceptually possible. Second, I (...) introduce a theory of moral motivation that supplements the intuitive responses to different amoralist cases. According to moral judgment purposivism (MJP), in rough approximation, a purpose of moral judgments is to motivate corresponding behaviors such that a mental state without this purpose is not a moral judgment. MJP is consistent with conceptual desiderata, provides an illuminating analysis of amoralist cases, and offers a step forward in the internalist-externalist debates. (shrink)

We do not live in a just world. This may be the least controversial claim one could make in political theory. But it is much less clear what, if anything, justice on a world scale might mean, or what the hope for justice should lead us to want in the domain of international or global institutions, and in the policies of states that are in a position to affect the world order. By comparison with the perplexing and undeveloped state of (...) this subject, domestic political theory is very well understood, with multiple highly developed theories offering alternative solutions to well-defined problems. By contrast, concepts and theories of global justice are in the early stages of formation, and it is not clear what the main questions are, let alone the main possible answers. I believe that the need for workable ideas about the global or international case presents political theory with its most important current task, and even perhaps with the opportunity to make a practical contribution in the long run, though perhaps only the very long run.

Timothy Williamson gives an original and provocative treatment of deep metaphysical questions about existence, contingency, and change, using the latest resources of quantified modal logic. Contrary to the widespread assumption that logic and metaphysics are disjoint, he argues that modal logic provides a structural core for metaphysics.

My interest in the issues considered here arose out of my great frustration in trying to attack the all-pervasive relativism of my students in introductory ethics courses at Virginia Polytechnic Institute and State University. I am grateful to my students for forcing me to take moral relativism and skepticism seriously and for compelling me to argue for my own dogmatically maintained version of moral objectivism. The result is before the reader. The conclusions reached here (which can be described either as (...) a minimal objectivism or as a moderate verson of relativism) are considerably weaker than those that I had expected and would have liked to have defended. I have arrived at these views kicking and screaming and have resisted them to the best of my ability. The arguments of this book are directed at those who deny that moral judgments can ever be correct (in any sense that is opposed to mistaken) and who also deny that we are ever rationally com pelled to accept one moral judgment as opposed to another. I have sought to take their views seriously and to fight them on their own grounds without making use of any assumptions that they would be unwilling to grant. My conclusion is that, while it is possible to refute the kind of extreme irrationalism that one often encounters, it is impossible to defend the kind of objectivist meta-ethical views that most of us want to hold, without begging the question against the non-objectivist.
