The generalized second law of thermodynamics states that entropy always increases when all event horizons are attributed with an entropy proportional to their area. We test the generalized second law by investigating the change in entropy when dust, radiation and black holes cross a cosmological event horizon. We generalize for flat, open and closed Friedmann–Robertson–Walker universes by using numerical calculations to determine the cosmological horizon evolution. In most cases, the loss of entropy from within the cosmological horizon is more than (...) balanced by an increase in cosmological event horizon entropy, maintaining the validity of the generalized second law of thermodynamics. However, an intriguing set of open universe models shows an apparent entropy decrease when black holes disappear over the cosmological event horizon. We anticipate that this apparent violation of the generalized second law will disappear when solutions are available for black holes embedded in arbitrary backgrounds. (shrink)
We consider the implications of a model for long-duration gamma-ray bursts in which the progenitor is spun up in a close binary by tidal interactions with a massive black-hole companion. We investigate a sample of such binaries produced by a binary population synthesis, and show that the model predicts several common features in the accretion on to the newly formed black hole. In all cases, the accretion rate declines as approximately t−5/3 until a break at a time of order 104 (...) s. The accretion rate declines steeply thereafter. Subsequently, there is flaring activity, with the flare peaking between 104 and 105 s, the peak time being correlated with the flare energy. We show that these times are set by the semi-major axis of the binary, and hence the process of tidal spin-up; furthermore, they are consistent with flares seen in the X-ray light curves of some long gamma-ray bursts.

Externalism about some mental property, M, is the thesis that whether a person (or other physical being) has M depends, not only on conditions inside the person.
A great deal of discussion in the recent literature has been devoted to the so-called 'McKinsey' paradox which purports to show that semantic externalism is incompatible with the sort of authoritative knowledge that we take ourselves to have of our own thought contents. In this paper I examine one influential epistemological response to this paradox which is due to Crispin Wright and Martin Davies. I argue that it fails to meet the challenge posed by McKinsey but that, if it (...) is set within an externalist epistemology, it may have application to a related paradox that concerns the problem of radical scepticism.

Martin Davies' criterion for the knowledge of implicit rules, viz. the causal systematicity of cognitive processes, is first exposed. Then the inference from causal systematicity of a process to syntactic properties of the input states is examined. It is argued that Davies' notion of a syntactic property is too weak to bear the conclusion that causal systematicity implies a language of thought as far as the input states are concerned. Next, it is shown that Davies' criterion leads (...) to a counterintuitive consequence: it groups together distributed connectionist systems with look-up tables. To avoid this consequence, a modified construal of causal systematicity is proposed and Davies' argument for the causal systematicity of thought is shown to be question-begging. It is briefly sketched how the modified construal links up with multiple dispositions of the same categorical base. Finally, the question of the causal efficacy of single rules is distinguished from the question of their psychological reality: implicit rules might be psychologically real without being causally efficacious.

Philosophical interest in introspection has a long and storied history, but only recently – with the 'scientific turn' in philosophy of mind – have philosophers sought to ground their accounts of introspection in psychological data. In particular, there is growing awareness of how evidence from clinical and developmental psychology might be brought to bear on long-standing debates about the architecture of introspection, especially in the form of apparent dissociations between introspection and third-person mental-state attribution. It is less often noticed that (...) this evidence needs to be interpreted with due sensitivity to distinctions between different types of introspection, for example, introspection of propositional attitudes (beliefs, desires) vs. introspection of phenomenally conscious states (pains, emotional feelings). As contemporary debates about the machinery of introspection – and debates about mindreading in general – move forward, these distinctions are likely to figure more prominently.

Smith (Cambridge: Cambridge University Press, 1996), 22–38. Defends a sophisticated form of the theory-theory of introspection, according to which we come to know at least some of our mental states (e.g., propositional attitudes) by reasoning from an innate folk-psychological theory. Fred Dretske, 'Introspection', in Naturalizing the Mind (Cambridge, MA: MIT Press, 1995), 39–63. Introduces and defends the idea of introspection as 'displaced perception'.

Defends a version of the 'inner sense' view of introspection in which mental state types are classified via their neural properties, and mental contents are classified via 'redeployment'. Alison Gopnik, 'How We Read Our Own Minds: The Illusion of First-Person Knowledge of Intentionality', Behavioral and Brain Sciences 16 (1993): 1–14. A noted psychologist defends a version of the theory-theory of introspection, citing evidence of developmental symmetries between first-person and third-person mental-state attribution.

Uta Frith and Francesca Happé, 'Theory of Mind and Self-Consciousness: What Is It Like to Be Autistic?'Mind and Language 14 (1999): 1–14. Appeals to evidence from autism to motivate the idea that first-person and third-person mental-state attribution have a common basis. Shaun Nichols and Stephen Stich, 'Reading One's Own Mind', in Mindreading: An Integrated Account of Pretence, Self-awareness, and Understanding other Minds (Oxford: Oxford University Press, 2003), 150–99.

What distinguishes 'inside access' from 'outside access' views of introspection?2. To what extent is the theory-theoretic approach to introspection wedded to the idea that first-person and third-person mindreading are mechanistically symmetric capacities?3. What reasons are there for distinguishing between different types of introspection, and why might those taxonomic distinctions matter for theory construction in this area?4. In what sense, if any, are personality traits introspectible?5. Debates about third-person mindreading have revolved around the relative merits of theory-theory and simulation theory, whereas debates about introspection have taken a slightly different focus. For example, no one has defended a simulation-theoretic account of introspection. Why might that be? (shrink)
The relationship of the author's intention to the meaning of a literary work has been a persistently controversial topic in aesthetics. Anti-intentionalists Wimsatt and Beardsley, in the 1946 paper that launched the debate, accused critics who fueled their interpretative activity by poring over the author's private diaries and life story of committing the 'fallacy' of equating the work's meaning, properly determined by context and linguistic convention, with the meaning intended by the author. Hirsch responded that context and convention are not (...) sufficient to determine a unique meaning for a text; to avoid radical ambiguity we must appeal to the author's intention, which actualizes one of the candidate meanings. Subsequent writers have defended refined versions of these views, and a variety of positions on the spectrum between them, in a debate that remains central to philosophical aesthetics. While much of the debate has focused on literature, similar questions arise with respect to the interpretation of visual artworks. Some of the readings listed below address this matter explicitly. Author Recommends: William K. Wimsatt and Monroe C. Beardsley, 'The Intentional Fallacy', Sewanee Review 54 (1946): 468–88. Locus classicus of the anti-intentionalist position: Wimsatt and Beardsley hold that appeal to the author's intention is always extraneous, since intention cannot override the role of linguistic convention and context in determining meaning. Criticism, they argue, should thus proceed by careful examination of the literary work rather than by sifting through biographical material that might hint at the author's intentions. E. D. Hirsch, Jr., Validity in Interpretation (New Haven, CT: Yale University Press, 1967). The seminal statement of actual intentionalism: Hirsch holds that 'meaning is an affair of consciousness and not of physical signs or things' (23), though he allows that linguistic convention constrains the meanings the author can intend for a particular utterance. He argues that the author's intention is necessary to fix meaning, since the application of conventions alone would typically leave a text wildly indeterminate. Alexander Nehamas, 'The Postulated Author: Critical Monism as a Regulative Ideal', Critical Inquiry 8 (1981): 133–49. Nehamas argues for a version of hypothetical intentionalism according to which interpretation is a matter of attributing an intended meaning to a hypothetical author, distinct from the historical writer. This view allows the interpreter to find meaning even in features of the work that may have been mere accidents on the part of the historical writer. Gary Iseminger, ed., Intention and Interpretation (Philadelphia, PA: Temple University Press, 1992). Intention and Interpretation is an outstanding collection including both classic and new essays representing most of the major viewpoints in the debate. Noël Carroll, 'Art, Intention, and Conversation', Intention and Interpretation , ed. Gary Iseminger (Philadelphia, PA: Temple University Press, 1992), 97–131. The essay defends modest actual intentionalism, according to which the work's meaning is one compatible both with the author's meaning intentions and with the conventionally allowable meanings of the text. Carroll holds that literature is on a continuum with ordinary conversation, to which an intentionalist analysis is apt; for this reason he rejects anti-intentionalism and hypothetical intentionalism, which emphasize the purported autonomy of literary works from their authors. Daniel Nathan, 'Irony, Metaphor, and the Problem of Intention', Intention and Interpretation , ed. Gary Iseminger (Philadelphia, PA: Temple University Press, 1992), 183–202. Nathan argues that even irony and metaphor, which are often thought to require an analysis in terms of the author's actual intentions, are in fact best understood on an anti-intentionalist approach. Jerrold Levinson, 'Intention and Interpretation in Literature', The Pleasures of Aesthetics: Philosophical Essays (Ithaca, NY: Cornell University Press, 1996), 175–213. Revised version of 'Intention and Interpretation: A Last Look', Intention and Interpretation , ed. Gary Iseminger (Philadelphia, PA: Temple University Press, 1992), 221–56. The essay defends a version of hypothetical intentionalism according to which the meaning of a literary work is the meaning that would be attributed to the actual author by members of the ideal audience. Levinson argues that literary works should be treated differently from everyday utterances, since it is a convention of literature that its works are substantially autonomous from their authors. Paisley Livingston, Art and Intention: A Philosophical Study (Oxford: Clarendon Press, 2005). Livingston examines competing accounts of the nature of intentions as they pertain to a variety of issues in the philosophy of art, including the ontology of art, the nature of authorship, and art interpretation. In chapter 6, Livingston argues for partial intentionalism, according to which some, but not all, of a work's meanings are non-redundantly determined by the author's intentions. Stephen Davies, 'Authors' Intentions, Literary Interpretation, and Literary Value', British Journal of Aesthetics 46 (2006): 223–47. Davies defends the value-maximizing view, according to which, when there is more than one conventional meaning consistent with the work's features, the meaning that should be attributed to the work is the one that makes the work out to be most aesthetically valuable. He allows for the attribution of multiple meanings when more than one candidate (approximately) maximizes the work's value.

Should literary works be seen as largely autonomous from their authors, even if we think that interpretation of ordinary utterances is properly a matter of ascertaining the speaker's intentions? 3. Are linguistic context and convention sufficient to determine the meaning of a literary work, or is the author's intention required to stave off an unacceptable degree of ambiguity? 4. Should the author's intentions about the genre or category to which the work belongs have a different status than intentions about the work's meaning? 5. Can the author's intentions have a non-redundant role to play in fixing meaning even if we take the role of context and linguistic convention seriously? 6. Should we expect the author's intention to play the same role (if any) in the interpretation of visual artworks that it plays in the interpretation of literature, or do differences between these two art forms require distinct approaches?

We analyse managerial discourse in corporate communication (‘CEO-speak’) during a 6-month period following a legitimacy-threatening event in the form of an incident in a German nuclear power plant. As discourses express specific stances expressed by a group of people who share particular beliefs and values, they constitute an important means of restoring organisational legitimacy when social rules and norms have been violated. Using an analytical framework based on legitimacy as a process of reciprocal sense-making and consisting of three levels of (...) analysis which capture the relationship between text and context, we investigate the discourse used by CEOs in their initial and subsequent accounts of the incident. We find that CEOs aim to negotiate a resolution between their initial account and organisational audiences’ incongruent interpretations of the event by adopting an ad hoc normative attitude to stakeholders. This manifests itself in the strategic use of the discourse of stakeholder engagement as a means of signalling change, yet maintaining the status quo. It suggests that CEOs strategically use discourse to manufacture organisational audiences’ consent regarding the continued operation of the nuclear power plant affected by the incident. Our findings contribute to the critical corporate communication literature which regards corporate narrative reporting as a means of consolidating the private interests of corporations, rather than increasing transparency and accountability.

It is commonly supposed that metaphysical modal claims are to be evaluated with respect to a single domain of possible worlds: a claim is metaphysically necessary just in case it is true in every possible world, and metaphysically possible just in case it is true in some possible world. We argue that the standard understanding is incorrect; rather, whether a given claim is metaphysically necessary or possible is relative to which world is indicatively actual. We motivate our view by attention (...) to discussions in Salmon 1989 and Fine 2005, in which various data are taken to support rejecting the transitivity of accessibility (Salmon) and modal monism (Fine); we argue that relativized metaphysical modality can accommodate these data compatible with both standard modal logic(s) and modal monism. Noting an analogy with two-dimensional semantics, we argue that metaphysical modality has a complex structure, reflecting what is counterfactually possible, relative to each indicatively actual world. In arguing for the need for relativization, we are broadly on the same side as Crossley and Humberstone (1977) and Davies and Humberstone (1979); our contribution here is, first, to offer distinctively metaphysical reasons for relativization, and second, to show that relativization can be incorporated in ways minimally departing from standard modal logic(s).

[First Paragraph] In his recent book, Implicature: Intention, Convention, and Principle in the Failure of Gricean Theory (1998), Wayne Davis argues that the Gricean approach to conversational implicature is bankrupt and offers a new approach of his own. Although I disagree with Davis both in general and in detail, I think nonetheless that the problems he raises'or close relatives of them-- are serious and important problems which should give any Gricean pause. This is an extremely worthwhile book, even for (...) those who disagree with it. (shrink)
