This article reports on an empirical investigation of long-term use of a groupware system in a spatially and massively distributed network of educators. It is a case study based investigation aimed at understanding the impacts of collaboration technology in supporting social interaction. The paradigm of social constructivism and the perspective of structuration are proposed as frameworks for understanding the impacts of technology on mediating social interaction. Utilizing these perspectives in an empirical investigation, the case study findings demonstrate how collaboration technology (...) can serve as a change agent in transforming the culture and structure of social interaction. This is enacted in two ways: through the various meanings which people construct when interacting with technology and in benefiting from the structural properties of a system through its technical affordances.

William Rowe’s a posteriori arguments for the non-existence of God are well-known. Rather less attention has been given, however, to Rowe’s intriguing a priori argument for atheism. In this paper, I examine the three published responses to Rowe’s a priori argument (due to Bruce Langtry, William Morris, and Daniel and Frances Howard-Snyder, respectively). I conclude that none is decisive, but I show that Rowe’s argument nevertheless requires more defence than he provides.
In recent decades, there has been astonishing growth in scientific theorizing about multiverses. Once considered outré or absurd, multiple universe theories appear to be gaining considerable scientific respectability. There are, of course, many such theories, including (i) Everett’s (1957) many worlds interpretation of quantum mechanics, defended by Deutsch (1997) and others; (ii) Linde’s (1986) eternal inflation view, which suggests that universes form like bubbles in a chaotically inflating sea; (iii) Smolin’s (1997) fecund universe theory, which proposes that universes are generated (...) through black holes; (iv) the cyclic model, recently defended using string/M theory by Steinhardt and Turok (2007), which holds that distinct universes are formed in a never-ending sequence of Big Bangs and Big Crunches; and (v) Tegmark’s (2007) “Level IV” multiverse, which contains many universes governed by distinct mathematical and scientific laws. While not all of these preclude each other, the details and implications of each one are hotly contested.1 In one area within the philosophy of religion (the debate concerning the “fine-tuning” argument), scientific multiverse theories are widely held to be hostile to theism. This is because such theories appear to account for the relevant data – the biophilic parameters of the universe we inhabit – without appeal to an intelligent designer. Yet, in recent years, several philosophers2 and one physicist3 have offered reasons for thinking that if theism is true, the actual world comprises (or probably comprises) many universes. I first set out some requirements – both scientific and otherwise – for such a theory. I then survey some problems such theories are held to face, and some prospects they are thought to have. Finally, I examine arguments both for and against the claim that multiverse theories can help theists respond to the problem of evil.. (shrink)
The ambition of this volume is twofold: to provide a comprehensive overview of the field and to serve as an indispensable reference work for anyone who wants to work in it. For example, any philosopher who hopes to make a contribution to the topic of the classical-quantum correspondence will have to begin by consulting Klaas Landsman’s chapter. The organization of this volume, as well as the choice of topics, is based on the conviction that the important problems in the (...) philosophy of physics arise from studying the foundations of the fundamental theories of physics. It follows that there is no sharp line to be drawn between philosophy of physics and physics itself. Some of the best work in the philosophy of physics is being done by physicists, as witnessed by the fact that several of the contributors to the volume are theoretical physicists: viz., Ellis, Emch, Harvey, Landsman, Rovelli, ‘t Hooft, the last of whom is a Nobel laureate. Key features - Definitive discussions of the philosophical implications of modern physics - Masterly expositions of the fundamental theories of modern physics - Covers all three main pillars of modern physics: relativity theory, quantum theory, and thermal physics - Covers the new sciences grown from these theories: for example, cosmology from relativity theory; and quantum information and quantum computing, from quantum theory - Contains special Chapters that address crucial topics that arise in several different theories, such as symmetry and determinism - Written by very distinguished theoretical physicists, including a Nobel Laureate, as well as by philosophers - Definitive discussions of the philosophical implications of modern physics - Masterly expositions of the fundamental theories of modern physics - Covers all three main pillars of modern physics: relativity theory, quantum theory, and thermal physics - Covers the new sciences that have grown from these theories: for example, cosmology from relativity theory; and quantum information and quantum computing, from quantum theory - Contains special Chapters that address crucial topics that arise in several different theories, such as symmetry and determinism - Written by very distinguished theoretical physicists, including a Nobel Laureate, as well as by philosophers.

God is traditionally taken to be a necessarily existing being who is unsurpassably powerful, knowledgeable, and good. The familiar problem of actual evil claims that the presence of gratuitous suffering in the actual world constitutes evidence against the existence of such a being. In contrast, the problem of possible evil claims that the possibility of bad worlds constitutes evidence against theism. How? It seems plausible to suppose that there are very bad possible worlds. But if God exists in every world, (...) then God exists in those, too. And if God exists in very bad worlds, some say, God is culpable for not ensuring that they are better. In what follows, I consider this argument, survey some responses, and offer a novel solution. Along the way, I argue that theists should maintain that the actual world is a multiverse featuring all and only universes worthy of being created and sustained by God, and – more controversially – I suggest that theists should embrace modal collapse: the claim that this multiverse is the only possible world.

God is traditionally taken to be a perfect being, and the creator and sustainer of all that is. So, if theism is true, what sort of world should we expect? To answer this question, we need an account of the array of possible worlds from which God is said to choose. It seems that either there is (a) exactly one best possible world; or (b) more than one unsurpassable world; or (c) an infinite hierarchy of increasingly better worlds. Influential arguments (...) for atheism have been advanced on each hierarchy, and these jointly comprise a daunting trilemma for theism. In this paper, I argue that if theism is true, we should expect the actual world to be a multiverse comprised of all and only those universes which are worthy of creation and sustenance. I further argue that this multiverse is the unique best of all possible worlds. Finally, I explain how his unconventional view bears on the trilemma for theism. (shrink)
Externalism holds that the individuation of mental content depends on factors external to the subject. This doctrine appears to undermine both the claim that there is a priori self-knowledge, and the view that individuals have privileged access to their thoughts. Tyler Burge’s influential inclusion theory of self-knowledge purports to reconcile externalism with authoritative self-knowledge. I first consider Paul Boghossian’s claim that the inclusion theory is internally inconsistent. I reject one line of response to this charge, but I endorse another. I (...) next suggest, however, that the inclusion theory has little explanatory value. (shrink)
In the central chapter of Can God Be Free?, William Rowe offers what amounts to an a priori argument for atheism. In what follows, I first clarify this argument, and I then defend it against recent criticisms due to William Hasker. Next, however, I outline four ways in which theists might plausibly reply to Rowe’s argument.
One historically significant model of God holds that God is a perfect being. Analytic philosophers of religion have typically understood this to mean that God is essentially unsurpassable in power, knowledge, goodness, and wisdom. Recently, however, several philosophers have argued that this is inconsistent with another common theistic position: the view that for any world that God can create, there is a better world that God could have created instead. The argument runs (roughly) as follows: if, no matter which world (...) God creates, there’s a better creatable one, then God’s action in creating a world is necessarily surpassable. And if God’s action in creating a world is necessarily surpassable, then God is necessarily surpassable. If this argument is sound, it reveals a serious flaw in an important model of God. In what follows, I set out this argument, and I then distinguish and evaluate four replies. (shrink)
In recent years, several philosophers have offered reasons for thinking that if theism is true, the actual world (likely) includes multiple universes. Some have further argued that a multiverse model can help theists respond to arguments from evil. The latter move has been criticized in various ways. In a forthcoming paper in THIS JOURNAL, Jason Megill offers a novel and ambitious meta-argument: he claims that the bare epistemic possibility of multiple universes defeats all arguments from evil. If Megill’s argument were (...) sound, this would be an enormously important result in the philosophy of religion. The problem of evil, after all, is widely thought to be one of the most serious objections to theism. It has been discussed throughout the history of philosophy, and has generated an enormous and very technical contemporary literature. But can the bare epistemic possibility of multiple universes really defeat all arguments from evil, both past and present, as Megill maintains? In what follows, I contend that Megill fails to establish premise a crucial premise in his argument. I conclude with a rival account of the effect of multiverse models of theism on the debate about evil. (shrink)
If one formulates Helmholtz's ideas about perception in terms of modern-day theories one arrives at a model of perceptual inference and learning that can explain a remarkable range of neurobiological facts. Using constructs from statistical physics it can be shown that the problems of inferring what cause our sensory inputs and learning causal regularities in the sensorium can be resolved using exactly the same principles. Furthermore, inference and learning can proceed in a biologically plausible fashion. The ensuing scheme rests on (...) Empirical Bayes and hierarchical models of how sensory information is generated. The use of hierarchical models enables the brain to construct prior expectations in a dynamic and context-sensitive fashion. This scheme provides a principled way to understand many aspects of the brain's organisation and responses. In this paper, we suggest that these perceptual processes are just one emergent property of systems that conform to a free-energy principle. The free-energy considered here represents a bound on the surprise inherent in any exchange with the environment, under expectations encoded by its state or configuration. A system can minimise free-energy by changing its configuration to change the way it samples the environment, or to change its expectations. These changes correspond to action and perception, respectively, and lead to an adaptive exchange with the environment that is characteristic of biological systems. This treatment implies that the system's state and structure encode an implicit and probabilistic model of the environment. We will look at models entailed by the brain and how minimisation of free-energy can explain its dynamics and structure. (shrink)

Anselmian theism holds that there necessarily exists a being, God, who is essentially unsurpassable in power, knowledge, goodness, and wisdom. This being is also understood to be the creator and sustainer of all that is. In contemporary analytic philosophy of religion, this role is generally understood as follows: God surveys the array of possible worlds, and in his wisdom selects exactly one for actualization, based on its axiological properties. In this paper, I discuss an under-appreciated challenge for this account of (...) the Anselmian God’s selection of a world. In particular, I urge that there are failures of comparability between various possible worlds, and I argue that, given certain assumptions, these failures threaten the rationality of God’s choice of a world. To the extent that rationality is deemed necessary for unsurpassability, this result also challenges the core Anselmian notion that God is an unsurpassable being. (shrink)
I defend the first premise of William Rowe’s well-known arguments from evil against influential criticisms due to William Alston. I next suggest that the central inference in Rowe’s arguments is best understood to move from the claim that we have an absence of evidence of a satisfactory theodicy to the claim that we have evidence of absence of such a theodicy. I endorse the view which holds that this move succeeds only if it is reasonable to believe that (roughly) if (...) there were such a theodicy, we would probably know it. After conceding that there may be modest prima facie support for this latter claim via the Principle of Credulity, I consider and reject four more ambitious arguments in its favour. I conclude that this necessary condition on Rowe’s crucial inference has not been shown to be satisfied. (shrink)
Possibly the most comprehensive collection of essays on Descartes' scientific writings ever published, this volume offers a detailed reassessment of his scientific work and its bearing on his philosophy. The 35 essays, written by some of the world's leading scholars, cover topics as diverse as optics, cosmology and medicine. The collection looks at Descartes' work in the sciences as an aspect of his natural-philosophical agenda and discusses: the central place of medicine in Descartes' overall project; the connections between his investigations (...) of specific psychological capacities and his ethics of self-government; and the debates and controversies into which he had his followers were drawn, and their role in shaping Cartesian natural philosophy; and other issues.

Since the Renaissance, dramatic theory has been strongly influenced, sometimes even dominated by Aristotle’s Poetics. Aristotle’s concept of tragedy has been perceived as both a descriptive and a normative concept: a description of a practice as it should be continued. This biased reading of ancient theory is not exceptional, but in the case of Aristotle’s Poetics, a particular question can be raised. Aristotle has written about tragedy, at a moment that tragedy had no meaningful political or civic function anymore. As (...) political theory—e.g. as developed in the Politics and the Art of Rhetoric—should contain the risks of transgression in political practice, so poetic theory can contain the risks of the representation of transgressions in poetic practices such as the performance of tragedy. Apart from an account on Aristotle’s Poetics as a integral part of his ethical and political theory, this article argues the (mis)readings of Aristotelian dramatic theory since the Renaissance, and especially in 17th century France are not coincidental. Aristotle’s theory itself fits neatly into a political-theoretical framework or, if one puts it more brutally, an ideology. The particular theatricality of French absolutism took clearly its advantage from this ideological (mis)readings of Aristotle. (shrink)
To Aristotle, spoken words are symbols, not of objects in the world, but of our mental experiences related to these objects. Presently there are two major strands of interpretation of Aristotle’s concept of the linguistic sign. First, there is the structuralist account offered by Coseriu (Geschichte der Sprachphilosophie. Von den Anfängen bis Rousseau, 2003 [1969], pp. 65–108) whose interpretation is reminiscent of the Saussurean sign concept. A second interpretation, offered by Lieb (in: Geckeler (Ed.) Logos Semantikos: Studia Linguistica in Honorem (...) Eugenio Coseriu 1921–1981, 1981) and Weidemann (in: Schmitter (Ed.) Geschichte der Sprachtheorie 2. Sprachtheorien der abendländischen Antike, 1991), says that Aristotle’s concept of the linguistic sign is similar to the one presented in Ogden and Richard’s (The meaning of meaning: A study of the influence of language upon thought and of the science of symbolism, 1970 [1923]) semiotic triangle. This paper starts off with an introductory outline of the so-called phýsei-thései discussion which started during presocratic times and culminated in Plato’s Cratylus. Aristotle’s concept of the linguistic sign is to be regarded as a solution to the stalemate position reached in the Cratylus. Next, a discussion is offered of both Coseriu’s and Lieb’s analysis. We submit that Aristotle’s concept of the linguistic sign shows features of both Saussure’s and Ogden and Richards’s sign concept but that it does not exclusively predict one of the two. We argue that Aristotle’s concept of the linguistic sign is based on three different relations which together evince his teleological as well empiricist point of view: one internal (symbolic) relation and two external relations, i.e. a likeness relation and a relation katà synthéken.

On what basis does God choose a possible world to make actual? Theists typically claim that God freely selects exactly one world on the basis of its axiological characteristics. But suppose that (a) there are infinitely many unsurpassable worlds from which to choose; or else that (b) there are no unsurpassable worlds, but instead an infinite hierarchy of increasingly better worlds. On each of these scenarios, philosophers have alleged that God is unable rationally to choose a world (...) for actualization. In the former case, God lacks sufficient reason to select any particular world, since there are infinitely many other equally good candidates. In the latter case, God lacks sufficient reason to select any particular world, since for any world there are infinitely many better candidates. These considerations generate arguments for atheism, as follows. On theism, God is supposed to be the explanation for this world’s being actual, and God requires sufficient reasons for action. So on either scenario (a) or (b), since there is an actual world, and since God could not have had a sufficient reason for selecting it, this world was not actualized by God. In response, defenders of theism have urged that God need not have sufficient reason for choosing a world on (a) or (b): God may defensibly choose a world at random. In what follows, I evaluate this reply. I conclude that it succeeds only on the enormously implausible assumption that there is exactly one randomizer available to God. (shrink)
God is traditionally understood to be a perfect being who is the creator and sustainer of all that is. God's creative and sustaining activity is often thought to involve choosing a possible world for actualization. It is generally said that either there is (a) exactly one best of all possible worlds, or there are (b) infinitely many increasingly better worlds, or else there are (c) infinitely many unsurpassable worlds within God's power to actualize. On each view, critics have offered arguments (...) for atheism that turn on God's choice of a world. In what follows, I first discuss some background issues, and I then survey the contemporary literature on these arguments. (shrink)
I first discuss Philo’s argument for divine amorality, and I distinguish it from his earlier criticisms of any inference from mundane data to divine benevolence. In Section 2, I diagnose deficiencies in two contrary interpretations of the argument for divine amorality. In Section 3, I offer three reasons for rejecting the surface meaning of this argument. In Section 4, I reveal Philo’s argument to be a sophisticated parody of both Cleanthes’ natural theology and his appeal to the passional influence of (...) the design hypothesis. Philo, I argue, does not intend to show that the Deity is probably amoral; rather, he intends to show Cleanthes – by literally arguing with him “in his own way” (DNR 2.11; 145) – that the tools of Cleanthes’ ‘experimental theism’ can equally be wielded in service of a wholly incompatible view.

I defend the first premise of William Rowe’s well-known arguments from evil against influential criticisms due to William Alston. I next suggest that the central inference in Rowe’s arguments is best understood to move from the claim that we have an absence of evidence of a satisfactory theodicy to the claim that we have evidence of absence of such a theodicy. I endorse the view which holds that this move succeeds only if it is reasonable to believe that (roughly) if (...) there were such a theodicy, we would probably know it.

Many theists hold that for any world x that God has the power to actualize, there is a better world, y, that God had the power to actualize instead of x. Recently, however, it has been suggested that this scenario is incompatible with traditional theism: roughly, it is claimed that no being can be essentially unsurpassable on this view, since no matter what God does in actualizing a world, it is possible for God (or some other being) to do better, (...) and hence it is possible for God (or some other being) to be better. In reply to an argument of this sort, Daniel and Frances Howard-Snyder offer the surprising claim that an essentially unsurpassable being could – consistently with his goodness and rationality – select a world for actualization at random. In what follows, I respond to the most recent contributions to this discussion. I criticize William Rowe’s new reply to the Howard-Snyders (but I endorse the spirit of one of his arguments), and I claim that Edward Wierenga’s new defence of the Howard-Snyders fails. I conclude that the Howard-Snyders’ argument fails to show that an essentially unsurpassable being could randomly choose a world for actualization. Accordingly, it fails to block an important argument for atheism. (shrink)
Klaas J. Kraay argues that the rational choice model for divine creation—according to which God chooses to actualize one world among possible alternatives based on its axiological properties—cannot succeed given failures of comparability across possible worlds. I argue that failure of comparability across worlds would not undermine the rationality of choosing one world to create among possible alternatives.
We tentatively propose two guiding principles for the construction of theories of physics, which should be satisfied by a possible future theory of quantum gravity. These principles are inspired by those that led Einstein to his theory of general relativity, viz. his principle of general covariance and his equivalence principle, as well as by the two mysterious dogmas of Bohr's interpretation of quantum mechanics, i.e. his doctrine of classical concepts and his principle of complementarity. An appropriate mathematical language for combining (...) these ideas is topos theory, a framework earlier proposed for physics by Isham and collaborators. Our "Principle of general tovariance" states that any mathematical structure appearing in the laws of physics must be definable in an arbitrary topos (with natural numbers object) and must be preserved under so-called geometric morphisms. This principle identifies geometric logic as the mathematical language of physics and restricts the constructions and theorems to those valid in intuitionism: neither Aristotle's principle of the excluded third nor Zermelo's Axiom of Choice may be invoked. Subsequently, our "Equivalence principle" states that any algebra of observables (initially defined in the topos Sets) is empirically equivalent to a commutative one in some other topos. (shrink)
This article raises the issue of growing inequalities in remuneration in Australia at a time of severe economic recession. The salary packages of the CEOs and senior managers of large Australian companies have been increased substantially in recent years often in spite of poor performance of the companies. At the same time real wages have either stagnated or, according to some researchers, have fallen in the same period. In addition unemployment has risen to unprecedented high levels (above 11%).The ethics of (...) such growing differentials are rarely addressed in the literature on compensation. It is mooted that the lack of ethical scrutiny affects staff morale and performance by non-managerial employees adversely. It tends to make a mockery of the philosophy of performance-based pay and the concept of appointment and promotion on the basis of merit. Without suggesting a widespread breakdown in norms and standards in Australia this article does question the quality of Australian management and raises the issue of appropriate corrections. Studies about the need for a new direction in management education and into the role of the Boards of Directors, their competence and functions have been conducted and others are in train. These suggest a preference for piecemeal reforms while, perhaps, more drastic measures are required. (shrink)
