According to authoritative Christian teaching, Jesus Christ is a single person existing in two natures, divinity and humanity. In attempting to understand this claim, the high-scholastic theologians often asked whether there was more than one existence in Christ. John Duns Scotus answers the question with a clear and strongly-formulated yes, and Thomists have sometimes suspected that his answer leads in a heretical direction. But before we can ask whether Scotus‘s answer is acceptable or not, we have to come to (...) a clear understanding of what his answer is. And before we can ask what his answer is, we have to come to a clear understanding of what question or questions he is trying to answer. In this paper I begin by explaining that the question about Christ‘s existence is ambiguous, i.e., that there are actually two questions hidden behind one formulation. Next I look at Scotus‘s writings on the topic in order to determine which question he is really trying to answer, and I argue that he is trying to answer both of them, even though he does not make this clear. Third, I provide an initial look at the answers that he gives. Fourth, I explain why these answers might seem problematic, especially from a Thomistic perspective. Fifth, I explain Scotus‘s answers in more detail and show that they are not problematic in the way that some Thomists have held. Indeed, at least some of Scotus‘s ideas are the very same ideas that Thomas spells out in one of his works. (shrink)

Borges’ The Circular Ruins tells the story of a magician who turns out to be a character in a dream. Leibowitz (2021) argues that this scenario undermines the rational indubitability of Descartes’ Cogito. The magician, he argues, is an unreal appearance and therefore does not exist. I argue that Borges drew a distinction between reality and existence and that he was right to do so. There are various senses of reality and the sense in which a dreamt character is unreal (...) poses no threat to their existence or to the indubitability of the Cogito. The magician is unreal because he is a mind-dependent, illusory and fake. Nonetheless, he can be certain that he thinks, therefore he is. (shrink)

In the exploratory study reported here, we tested the efficacy of an intervention designed to train teenagers with Möbius syndrome (MS) to increase the use of alternative communication strategies (e.g., gestures) to compensate for their lack of facial expressivity. Specifically, we expected the intervention to increase the level of rapport experienced in social interactions by our participants. In addition, we aimed to identify the mechanisms responsible for any such increase in rapport. In the study, five teenagers with MS interacted with (...) three naïve participants without MS before the intervention, and with three different naïve participants without MS after the intervention. Rapport was assessed by self-report and by behavioral coders who rated videos of the interactions. Individual non-verbal behavior was assessed via behavioral coders, whereas verbal behavior was automatically extracted from the sound files. Alignment was assessed using cross recurrence quantification analysis and mixed-effects models. The results showed that observer-coded rapport was greater after the intervention, whereas self-reported rapport did not change significantly. Observer-coded gesture and expressivity increased in participants with and without MS, whereas overall linguistic alignment decreased. Fidgeting and repetitiveness of verbal behavior also decreased in both groups. In sum, the intervention may impact non-verbal and verbal behavior in participants with and without MS, increasing rapport as well as overall gesturing, while decreasing alignment. (shrink)

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

Searle’s Chinese Room Argument (CRA) has been the object of great interest in the philosophy of mind, artificial intelligence and cognitive science since its initial presentation in ‘Minds, Brains and Programs’ in 1980. It is by no means an overstatement to assert that it has been a main focus of attention for philosophers and computer scientists of many stripes. It is then especially interesting to note that relatively little has been said about the detailed logic of the argument, whatever significance (...) Searle intended CRA to have. The problem with the CRA is that it involves a very strong modal claim, the truth of which is both unproved and highly questionable. So it will be argued here that the CRA does not prove what it was intended to prove. (shrink)

We argue that many recent philosophical discussions about the reference of everyday concepts of intentional states have implicitly been predicated on descriptive theories of reference. To rectify this, we attempt to demonstrate how a causal theory can be applied to intentional concepts. Specifically, we argue that some phenomena in early social de- velopment ðe.g., mimicry, gaze following, and emotional contagionÞ can serve as refer- ence fixers that enable children to track others’ intentional states and, thus, to refer to those states. (...) This allows intentional concepts to be anchored to their referents, even if folk psy- chological descriptions turn out to be false. (shrink)

The ontology of decision theory has been subject to considerable debate in the past, and discussion of just how we ought to view decision problems has revealed more than one interesting problem, as well as suggested some novel modifications of classical decision theory. In this paper it will be argued that Bayesian, or evidential, decision-theoretic characterizations of decision situations fail to adequately account for knowledge concerning the causal connections between acts, states, and outcomes in decision situations, and so they are (...) incomplete. Second, it will be argues that when we attempt to incorporate the knowledge of such causal connections into Bayesian decision theory, a substantial technical problem arises for which there is no currently available solution that does not suffer from some damning objection or other. From a broader perspective, this then throws into question the use of decision theory as a model of human or machine planning. (shrink)

The predominant view in developmental psychology is that young children are able to reason with the concept of desire prior to being able to reason with the concept of belief. We propose an explanation of this phenomenon that focuses on the cognitive tasks that competence with the belief and desire concepts enable young children to perform. We show that cognitive tasks that are typically considered fundamental to our competence with the belief and desire concepts can be performed with the concept (...) of desire in the absence of competence with the concept of belief, whereas the reverse is considerably less feasible.

Understanding when it is acceptable to interrupt a joint activity is an important part of understanding what cooperation entails. Philosophical analyses have suggested that we should release our partner from a joint activity anytime the activity conflicts with fulfilling a moral obligation. To probe young children’s understanding of this aspect, we investigated whether 3-year-old children (N = 60) are sensitive to the legitimacy of motives (selfish condition vs. moral condition) leading agents to intentionally interrupt their joint activity. We measured whether (...) children protested or released their partner by scoring their reactions. Our results indicate that children did not manifest different reactions when the motive behind their partner leaving was moral than when the motive was selfish. However, our data showed a stable pattern: regardless of the partner’s motives, some 3-year-olds take initiatives to release their partners from joint activity, suggesting that measuring release is a valuable tool for investigating joint action. -/- .

Joint actions often require agents to track others’ actions while planning and executing physically incongruent actions of their own. Previous research has indicated that this can lead to visuomotor interference effects when it occurs outside of joint action. How is this avoided or overcome in joint actions? We hypothesized that when joint action partners represent their actions as interrelated components of a plan to bring about a joint action goal, each partner’s movements need not be represented in relation to distinct, (...) incongruent proximal goals. Instead they can be represented in relation to a single proximal goal – especially if the movements are, or appear to be, mechanically linked to a more distal joint action goal. To test this, we implemented a paradigm in which participants produced finger movements that were either congruent or incongruent with those of a virtual partner, and either with or without a joint action goal (the joint flipping of a switch, which turned on two light bulbs). Our findings provide partial support for the hypothesis that visuomotor interference effects can be reduced when two physically incongruent actions are represented as mechanically interdependent contributions to a joint action goal.

The distinction between the essential and the accidental characteristics of a thing should be understood not in modal terms (the received view) nor in definitional terms (Fine’s recent proposal) but as follows: an essential characteristic of a thing is one that is not explained by any other of that thing’s characteristics, and an accidental characteristic of a thing is one that is so explained. Various versions of this proposal can be formulated.

The paper takes up a traditional view that has also been a part of some recent analytic metaphysics, namely, the view that substance is to be understood in terms of independence. Taking as my point of departure some recent remarks by Kit Fine, I propose reviving the Aristotelian-scholastic idea that the sense in which substances are independent is that they are non-inherent, and I do so by developing a broad notion of inherence that is more usable in the context of (...) contemporary analytic metaphysics than the traditional notion is. I end by showing how non-inherence, while necessary for being a substance, cannot be taken as sufficient without some qualifying remarks. (shrink)

Discusses the old problem of how to characterize apparently intentional states that appear to lack objects. In tandem with critically discussing a recent proposal by Tim Crane, I develop the line of reasoning according to which talking about intentional objects is really a way of talking about intentional states—in particular, it’s a way of talking about their satisfaction-conditions.

In recent years, there has been a heated debate about how to interpret findings that seem to show that humans rapidly and automatically calculate the visual perspectives of others. In the current study, we investigated the question of whether automatic interference effects found in the dot-perspective task (Samson, Apperly, Braithwaite, Andrews, & Bodley Scott, 2010) are the product of domain-specific perspective-taking processes or of domain-general “submentalizing” processes (Heyes, 2014). Previous attempts to address this question have done so by implementing inanimate (...) controls, such as arrows, as stimuli. The rationale for this is that submentalizing processes that respond to directionality should be engaged by such stimuli, whereas domain-specific perspective-taking mechanisms, if they exist, should not. These previous attempts have been limited, however, by the implied intentionality of the stimuli they have used (e.g. arrows), which may have invited participants to imbue them with perspectival agency. Drawing inspiration from “novel entity” paradigms from infant gaze-following research, we designed a version of the dot-perspective task that allowed us to precisely control whether a central stimulus was viewed as animate or inanimate. Across four experiments, we found no evidence that automatic “perspective-taking” effects in the dot-perspective task are modulated by beliefs about the animacy of the central stimulus. Our results also suggest that these effects may be due to the task-switching elements of the dot-perspective paradigm, rather than automatic directional orienting. Together, these results indicate that neither the perspective-taking nor the standard submentalizing interpretations of the dot-perspective task are fully correct. (shrink)

According to Christian belief, Jesus Christ is a divine person who became “incarnate,” i.e., who became human. A key event in the second act of the drama of creation and redemption, the incarnation could not have failed to interest Aquinas, and he discusses it in a number of places. A proper understanding of what he thought about it is thus part of any complete understanding of his work. It is, furthermore, a window into his ideas on a variety of other (...) topics: God, human nature, language, substance, and so on. Finally, it forces us to come to grips with what is at stake in acknowledging that Aquinas was not only a philosopher but a theologian as well. (shrink)

Joint attention is a social-cognitive phenomenon in which two or more agents direct their attention together towards the same object. Definitions range from this rather broad conception to more specific definitions which require that, in addition, attention be directed to the same aspect of that object and that agents need to be mutually aware of their jointly attending. Joint attention is an important coordination mechanism in joint action. The capacity for engaging in joint attention, in particular in the sense of (...) this narrower definition, is frequently taken to indicate the presence of theory of mind in the participating agents, and is also implicated in the development of theory of mind. However, the prominence of sensorimotor components in establishing and sustaining episodes of joint attention — e.g., eye and head movements, pointing and vocalizations — suggests that sensorimotor approaches to social interaction may be well-placed to account for important parts of joint attention without invoking theory-of-mind abilities, and may therefore provide a valuable alternative to approaches emphasizing theory of mind. In particular, sensorimotor accounts may explain aspects of joint attention through the dynamics and regularities in the sensorimotor processes that coordinate the activities of the agents. (shrink)

An overview of Hugh’s thought, focusing on philosophical issues.

Subjectivism about normativity (SN) is the view that norms are never intrinsic to things but are instead always imposed from without. After clarifying what SN is, I argue against it on the basis of its implications concerning intentionality. Intentional states with the mind-to-world direction of fit are essentially norm-subservient, i.e., essentially subject to norms such as truth, coherence, and the like. SN implies that nothing is intrinsically an intentional state of the mind-to-world sort: its being such a state is only (...) a status relative to the imposition of a norm. If one rejects this view of mind-to-world states, then one has grounds for rejecting SN itself. If one accepts it, an infinite regress arises that makes it impossible for norms to be imposed, which means that SN has undermined itself. (shrink)

According to Christian doctrine as formulated by the Council of Chalcedon (451), Christ is one person (one supposit, one hypostasis) existing in two natures (two essences), human and divine. The human and divine natures are not merged into a third nature, nor are they separated from one another in such a way that the divine nature goes with one person, namely, the Word of God, and the human nature with another person, namely, Jesus of Nazareth. The two natures belong to (...) just one person, and the one person has two distinct natures. Chalcedon‟s justly-famous formula brought the debate into sharper focus and ruled out certain options, but of course it did not bring the arguments to a complete end. More councils,more debates, and more questions were to follow, although the range of disagreement tended to narrow. In the medieval Latin West, Peter Lombard (†1160) identified in book III of the Sententiae three “opinions” on the topic, but by the middle of the thirteenth century, it was widely agreed that only one of them was orthodox teaching. This relative unity of thought provided the space within which more detailed issues could be debated, and one of the most interesting of these concerned existence (esse): how many existences are there in Christ? Since Christ is only one person, it might seem that he has only one existence. On the other hand, he has two natures, so perhaps instead he has more than one existence. In this one paper, my goal is rather modest. I discuss only a few of the relevant authors, and I focus primarily on which questions they were asking. I proceed as follows. I first look at Thomas Aquinas, whose remarks on these topics had such a large influence on the debate later in the thirteenth and fourteenth centuries. Crucial will be certain distinctions that Thomas makes, distinctions we can see as disambiguating the question we began with, namely, „How many existences are there in Christ?‟. After that I will look at how one of those distinctions makes its appearance in the writings of two post-Thomistic authors, Giles of Rome and Godfrey of Fontaines. (shrink)

In my commentary I will address the following topics: (i) what it means to speak of the philosophically interesting points in Augustine; (ii) whether Confessions VII is really about the Trinity; (iii) Augustine‘s intentions in Confessions VII; (...) (iv) King‘s hypostatic interpretation‖;(v) Christology. (shrink)

Patrick Toner has recently criticized accounts of substance provided by Kit Fine, E. J. Lowe, and the author, accounts which say (to a first approximation) that substances cannot depend on things other than their own parts. On Toner’s analysis, the inclusion of this parts exception results in a disjunctive definition of substance rather than a unified account. In this paper (speaking only for myself, but in a way that would, I believe, support the other authors that Toner discusses), I first (...) make clear what Toner’s criticism is, and then I respond to it. Including the parts exception is not the adding of a second condition but instead the creation of a new single condition. Since it is not the adding of a condition, the result is not disjunctive. Therefore, the objection fails. (shrink)

In this paper I explain Thomas Aquinas's view that Christ is a composite person, and then I explain the role of Christ's compositeness in Thomas‘s solutions to a range of Christological problems. On the topics I will be discussing, Thomas‘s views did not change significantly over the course of his career; for the sake of simplicity, then, I will focus on texts from the Summa theologiae, citing parallels in the notes.

Anyone who tries to understand categories soon runs into the problem of giving an account of the unity of a category. Call this the “unity problem.” In this essay, I describe a distinctive and under-studied version of the unity problem and discuss how it might be solved. First, I describe various versions of the unity problem. Second, I focus on one version and argue that it is best dealt with by thinking of at least some categories as “norm-constituted,” in a (...) sense that I try to make clear. Third, I discuss some objections to my proposal. Fourth, I compare norm -constituted categories to categories that are normative in a different sense. Fifth, I briefly discuss the possibility of grounding the normativity of norm-constituted categories. Finally, I raise a few questions for further research. (shrink)

In his recent "Thomas vs. Thomas: A New Approach to Nagel's Bat Argument", Yujin Nagasawa interprets Thomas Nagel as making a certain argument against physicalism and objects that this argument transgresses a principle, laid down by Thomas Aquinas, according to which inability to perform a pseudo-task does not count against an omnipotence claim. Taking Nagasawa's interpretation of Nagel for granted, I distinguish different kinds of omnipotence claims and different kinds of pseudo-tasks, and on that basis show that Nagasawa's criticism of (...) Nagel is unsuccessful. I also show how his reflections do nonetheless point to a limitation of the approach he means to criticize. (shrink)

For each positive n , two alternative axiomatizations of the theory of strings over n alphabetic characters are presented. One class of axiomatizations derives from Tarski's system of the Wahrheitsbegriff and uses the n characters and concatenation as primitives. The other class involves using n character-prefixing operators as primitives and derives from Hermes' Semiotik. All underlying logics are second order. It is shown that, for each n, the two theories are definitionally equivalent [or synonymous in the sense of deBouvere]. It (...) is further shown that each member of one class is synonymous with each member of the other class; thus that all of the theories are definitionally equivalent with each other and with Peano arithmetic. Categoricity of Peano arithmetic then implies categoricity of each of the above theories. (shrink)

The social welfare functional approach to social choice theory fails to distinguish a genuine change in individual well-beings from a merely representational change due to the use of different measurement scales. A generalization of the concept of a social welfare functional is introduced that explicitly takes account of the scales that are used to measure well-beings so as to distinguish between these two kinds of changes. This generalization of the standard theoretical framework results in a more satisfactory formulation of welfarism, (...) the doctrine that social alternatives are evaluated and socially ranked solely in terms of the well-beings of the relevant individuals. This scale-dependent form of welfarism is axiomatized using this framework. The implications of this approach for characterizing classes of social welfare orderings are also considered. (shrink)

The fact that Gilbert Ryle and J.L. Austin seem to disagree about the ordinary use of words such as ‘voluntary’, ‘involuntary’, ‘voluntarily’, and ‘involuntarily’ has been taken to cast doubt on the methods of ordinary language philosophy. As Benson Mates puts the worry, ‘if agreement about usage cannot be reached within so restricted a sample as the class of Oxford Professors of Philosophy, what are the prospects when the sample is enlarged?’ (Mates, Inquiry 1:161–171, 1958, p. 165). In this chapter, (...) we evaluate Mates’s criticism alongside Ryle’s and Austin’s specific claims about the ordinary use of these words, assessing these claims against actual examples of ordinary use drawn from the British National Corpus (BNC).

In applying these methods, we show where and to what extent Ryle’s and Austin’s accounts of the use of the target terms are accurate as well as where they miss important aspects of ordinary use, and we demonstrate the usefulness of this new combination of methods. At the heart of our approach is a commitment to the idea that systematically looking at actual uses of expressions is an essential component of any approach to ordinary language philosophy. (shrink)

This paper shows that Russell’s theory of descriptions gives the wrong se-mantics for definite descriptions occurring in questions and imperatives.

According to the computational theory of mind , to think is to compute. But what is meant by the word 'compute'? The generally given answer is this: Every case of computing is a case of manipulating symbols, but not vice versa - a manipulation of symbols must be driven exclusively by the formal properties of those symbols if it is qualify as a computation. In this paper, I will present the following argument. Words like 'form' and 'formal' are ambiguous, as (...) they can refer to form in either the syntactic or the morphological sense. CTM fails on each disambiguation, and the arguments for CTM immediately cease to be compelling once we register that ambiguity. The terms 'mechanical' and 'automatic' are comparably ambiguous. Once these ambiguities are exposed, it turns out that there is no possibility of mechanizing thought, even if we confine ourselves to domains where all problems can be settled through decision-procedures. The impossibility of mechanizing thought thus has nothing to do with recherché mathematical theorems, such as those proven by Gödel and Rosser. A related point is that CTM involves, and is guilty of reinforcing, a misunderstanding of the concept of an algorithm. (shrink)

Ordinarily counterfactuals are seen as making statements about states of affairs, albeit ones that hold in merely possible or alternative worlds. Thus analyzed, nearly all counterfactuals turn out to be incoherent. Any counterfactual, thus analyzed, requires that there be a metaphysically (not just epistemically) possible world w where the laws are the same as here, and where almost all of the facts are the same as here. (The factual differences relate to the antecedent and consequent of the counter-factual.) But, as (...) I show, this requirement typically involves the positing of worlds whose necessary non-existence can be shown by fairly elementary deductions. Further, the possible-worlds analysis of counterfactuals is guilty of covert circularity. For, thus analyzed, counterfactuals can only be understood in terms of laws of nature (the laws that apply here are assumed in the hypothetical world - except in the atypical case where the counterfactual is also a counter-nomic). But the concept of a law cannot itself be defined except in terms of the notion of a counterfactual (a law is given by a counterfactual-supporting proposition). I give a purely epistemic analysis of counterfactuals, arguing that they are crypto-probability propositions. I also argue that the relevant kind of probability can be defined wholly in terms of what has happened (not what would happen and not even what must happen in a nomic sense). So my analysis isn’t guilty of any kind of circularity. (shrink)

When the benefits of surgery do not outweigh the harms or where they do not clearly do so, surgical interventions become morally contested.

The semantic rules governing natural language quantifiers (e.g. "all," "some," "most") neither coincide with nor resemble the semantic rules governing the analogues of those expressions that occur in the artificial languages used by semanticists. Some semanticists, e.g. Peter Strawson, have put forth data-consistent hypotheses as to the identities of the semantic rules governing some natural-language quantifiers. But, despite their obvious merits, those hypotheses have been universally rejected. In this paper, it is shown that those hypotheses are indeed correct. Moreover, data-consistent (...) hypotheses are put forth as to the identities of the semantic rules governing the words "most" and "many," the semantic rules governing which semanticists have thus far been unable to identify. The points made in this paper are anticipated in a paper, published in the same issue of the Journal of Pragmatics, by Andrzej Boguslawski. (shrink)

Linguistic expressions must be decrypted if they are to transmit information. Thoughts need not be decrypted if they are to transmit information. Therefore thought-processes do not consist of linguistic expressions: thought is not linguistic. A consequence is that thought is not computational, given that a computation is the operationalization of a function that assigns one expression to some other expression (or sequence of expressions).

A brief but rigorous description of the logical structure of mathematical truth.

A series of representations must be semantics-driven if the members of that series are to combine into a single thought: where semantics is not operative, there is at most a series of disjoint representations that add up to nothing true or false, and therefore do not constitute a thought at all. A consequence is that there is necessarily a gulf between simulating thought, on the one hand, and actually thinking, on the other. A related point is that a popular doctrine (...) - the so-called 'computational theory of mind' (CTM) - is based on a confusion. CTM is the view that thought-processes consist in 'computations', where a computation is defined as a 'form-driven' operation on symbols. The expression 'form-driven operation' is ambiguous, as it may refer either to syntax-driven operations or to morphology-driven operations. Syntax-driven operations presuppose the existence of operations that are driven by semantic and extra-semantic knowledge. So CTM is false if the terms 'computation' and 'form-driven operation' are taken to refer to syntax-driven operations. Thus, if CTM is to work, those expressions must be taken to refer to morphology-driven operations. CTM therefore fails, given that an operation must be semantics-driven if it is to qualify as a thought. CTM therefore fails on each possible disambiguation of the expressions 'formal operation' and 'computation,' and it is therefore false. (shrink)

The meaning of morpheme (a minimal unit of linguistic significance) cannot diverge from what it is taken to mean. But the meaning of a complex expression can diverge without limit from what it is taken to mean, given that the meaning of such an expression is a logical consequence of the meanings of its parts, coupled with the fact that people are not infallible ratiocinators. Nonetheless, given Chomsky’s distinction between competence (ability) and performance (ability to deploy ability), what a complex (...) expression means does, after a fashion, coincide with what it is taken to mean: to the extent that speaker-performance approximates to speaker-competence---i.e. to the extent that people are able to operationalize their linguistic competence---what speakers take complex expressions to mean coincides with they in fact mean; and herein lies an answer to the question “what is linguistic meaning?” that holds with respect to both simple and complex expressions.

Sense-perceptions do not have to be deciphered if their contents are to be uploaded, the reason being that they are presentations, not representations. Linguistic expressions do have to be deciphered if their contents are to be uploaded, the reason being that they are representations, not presentations. It is viciously regressive to suppose that information-bearing mental entities are categorically in the nature of representations, as opposed to presentations, and it is therefore incoherent to suppose that thought is mediated by expressions or, (...) therefore, by linguistic entities. Attempts to neutralize this criticism inevitably overextend the concept of what it is to be a linguistic symbol, the result being that such attempts eviscerate the very position that it is their purpose to defend. Also, it is inherent in the nature of such attempts that they assume the truth of the view that for a given mental entity to bear this as opposed to that information is for that entity to have this as opposed to that causal role. This view is demonstrably false, dooming to failure the just-mentioned attempts to defend the contention that thought is in all cases mediated by linguistic symbols. (shrink)

What are laws, and do they necessarily have any basis in morality? The present work argues that laws are governmental assurances of protections of rights and that concepts of law and legal obligation must therefore be understood in moral terms. There are, of course, many immoral laws. But once certain basic truths are taken into account – in particular, that moral principles have a “dimension of weight”, to use an expression of Ronald Dworkin’s, and also that principled relations are not (...) always expressed by perfect statistical concomitances – the existence of iniquitous laws poses no significant threat to a moralistic analysis of law. Special attention is paid to the debate between Ronald Dworkin and H.L.A. Hart. Dworkin’s over-all position is argued to be correct, but issue is taken with his argument for that position. Hart’s analysis is found to be vitiated by an impoverished conception of morality and also of the nature of government. Our analysis of law enables us to answer three questions that, at this juncture of history, are of special importance: Are there international laws? If not, could such laws exist? And if they could exist, would their existence necessarily be desirable? The answers to these questions are, respectively: “no”, “yes”, and “no.” Our analysis of law enables us to hold onto the presumption that so-called legal interpretation is a principled endeavor, and that some legal interpretations are truer to existing laws than others. At the same time, it accommodates the obvious fact that the sense in which a physicist interprets meter-readings, or in which a physician interprets a patient’s symptoms, is different from the sense in which judges interpret the law. So our analysis of law enables us to avoid the extreme views that have thus far dominated debates concerning the nature of legal interpretation. On the one hand, it becomes possible to avoid the cynical view (held by the so-called “legal realists”) that legal interpretation is mere legislation and that no legal interpretation is more correct than any other. On the other hand, it becomes possible to avoid Blackstone’s view (rightly descried by Austin as a “childish fiction”) that judges merely discover, and do not create, the law. (shrink)

"Jim would still be alive if he hadn't jumped" means that Jim's death was a consequence of his jumping. "x wouldn't be a triangle if it didn't have three sides" means that x's having a three sides is a consequence its being a triangle. Lewis takes the first sentence to mean that Jim is still alive in some alternative universe where he didn't jump, and he takes the second to mean that x is a non-triangle in every alternative universe where (...) it doesn't have three sides. Why did Lewis have such obviously wrong views? Because, like so many of his contemporaries, he failed to grasp the truth that it is the purpose of the present paper to demonstrate, to wit: No coherent doctrine assumes that statements about possible worlds are anything other than statements about the dependence-relations governing our world. The negation of this proposition has a number of obviously false consequences, for example: all true propositions are necessarily true (there is no modal difference between "2+2=4" and "Socrates was bald"); all modal terms (e.g. "possible," "necessary") are infinitely ambiguous; there is no difference between laws of nature (e.g. "metal expands when heated") and accidental generalizations (e.g. "all of the coins in my pocket are quarters"); and there is no difference between the belief that 1+1=2 and the belief that arithmetic is incomplete. Given that possible worlds are identical with mathematical models, it follows that the concept of model-theoretic entailment is useless in the way of understanding how inferences are drawn or how they should be drawn. Given that the concept of formal-entailment is equally useless in these respects, it follows that philosophers and mathematicians have simply failed to shed any light on the nature of the consequence-relation. Q's being either a formal or a model-theoretic consequence of P is parasitic on its bearing some third, still unidentified relation to P; and until this relation has been identified, the discipline of philosophical logic has yet to begin.

This paper reports on an ongoing ARC Discovery Project that is conducting design research into learning in collaborative virtual worlds (CVW).The paper will describe three design components of the project: (a) pedagogical design, (b)technical and graphics design, and (c) learning research design. The perspectives of each design team will be discussed and how the three teams worked together to produce the CVW. The development of productive failure learning activities for the CVW will be discussed and there will be an interactive (...) demonstration of the project's CVW. (shrink)
