While historians of scientific method have recently called attention to the views of many of John Stuart Mill's contemporaries on the relation between probability and inductive inference, little if any note has been taken of Mill's own vigorous attack on the received "Laplacean" interpretation of probability in the first (1843) edition of the System of Logic. This paper examines the place of Mill's critique, both in the overall framework of his philosophy, and in the tradition of assessing the (...) so-called "probability of causes". It also offers an account of why, in later editions of the work, Mill appears to adopt a much more sympathetic stance toward the received view. (shrink)
What is encoded in working memory may be a content-addressable pointer, but a critical portion of the information that is addressed includes the motor information to achieve deictic reference in the environment. Additionally, the same strategy that is used to access environment information just in time for its use may also be used to access long-term memory via the pre-frontal cortex.
The project of constructing a logic of scientific inference on the basis of mathematical probability theory was first undertaken in a systematic way by the mid-nineteenth-century British logicians Augustus De Morgan, George Boole and William Stanley Jevons. This paper sketches the origins and motivation of that effort, the emergence of the inverse probability (IP) model of theory assessment, and the vicissitudes which that model suffered at the hands of its critics. Particular emphasis is given to the influence which competing interpretations (...) of probability had on the project, and to the role of the 'lottery' or 'ballot box' metaphor in the philosophical imagination of the proponents of the IP model.

In this philosophically sophisticated and historically significant work, John H. Zammito reconstructs Kant's composition of The Critique of Judgment and reveals that it underwent three major transformations before publication. He shows that Kant not only made his "cognitive" turn, expanding the project from a "Critique of Taste" to a Critique of Judgment but he also made an "ethical" turn. This "ethical" turn was provoked by controversies in German philosophical and religious culture, in particular the writings of Johann Herder and (...) the Sturm und Drang movement in art and science, as well as the related pantheism controversy. Such topicality made the Third Critique pivotal in creating a "Kantian" movement in the 1790s, leading directly to German Idealism and Romanticism. The austerity and grandeur of Kant's philosophical writings sometimes make it hard to recognize them as the products of a historical individual situated in the particular constellation of his time and society. Here Kant emerges as a concrete historical figure struggling to preserve the achievements of cosmopolitan Aufkl-rung against challenges in natural science, religion, and politics in the late 1780s. More specifically Zammito suggests that Kant's Third Critique was animated throughout by a fierce personal rivalry with Herder and by a strong commitment to traditional Christian ideas of God and human moral freedom. "A work of extraordinary erudition. Zammito's study is both comprehensive and novel, connecting Kant's work with the aesthetic and religious controversies of the late eighteenth century. He seems to have read everything. I know of no comparable historical study of Kant's Third Critique."-Arnulf Zweig, translator and editor of Kant's ;IPhilosophical Correspondence, 1759-1799;X "An intricate, subtle, and exciting explanation of how Kant's thinking developed and adjusted to new challenges over the decade from the first edition of the Critique of Pure Reason to the appearance of the Critique of Judgment.

John Searle has argued that the aim of strong AI of creating a thinking computer is misguided. Searle’s Chinese Room Argument purports to show that syntax does not suffice for semantics and that computer programs as such must fail to have intrinsic intentionality. But we are not mainly interested in the program itself but rather the implementation of the program in some material. It does not follow by necessity from the fact that computer programs are defined syntactically that (...) the implementation of them cannot suffice for semantics. Perhaps our world is a world in which any implementation of the right computer program will create a system with intrinsic intentionality, in which case Searle’s Chinese Room Scenario is empirically (nomically) impossible. But, indeed, perhaps our world is a world in which Searle’s Chinese Room Scenario is empirically (nomically) possible and that the silicon basis of modern day computers are one kind of material unsuited to give you intrinsic intentionality. The metaphysical question turns out to be a question of what kind of world we are in and I argue that in this respect we do not know our modal address. The Modal Address Argument does not ensure that strong AI will succeed, but it shows that Searle’s challenge on the research program of strong AI fails in its objectives. (shrink)
Erich Rast, Context as Assumptions.MSH Lorraine Preprints 2010 of the Proceedings of the Epiconfor Workshop on Epistemology, Nancy 2009.score: 27.0
In the tradition of Stalnaker (1978,2002, context can be regarded as a set of assumptions that are mutually shared by a group of epistemic agents.An obvious generalization of this view is to explicitly represent each agent’s assumptions in a given situation and update them accordingly when new information is accepted. I lay out a number of philosophical and linguistic requirements for using such a model in order to describe communication of ideally-rational agents. In particular,the following questions are addressed: -/- 1. (...) What is the logical status of assumptions as opposed to rational belief, how are these assumptions generated from an underlying belief base in a given interpretation situation,and how are assumptions revised/contracted? -/- 2.What kind of ideal reasoning processes underly the interpretation of ‘incomplete’ content that may for example be obtained by an agent from an utterance by deriving some literal meaning from the lexicon and a grammar? -/- Regarding the first set of questions, my proposal is to consider assumptions akin to rational belief, but not stronger than modal logic KD, since positive and negative introspection do not seem to hold for them.Given that, an obvious question is what the relation between beliefs and assumptions is. One possible answer is to generate an agent’s assumptions from an agent’s beliefs in a given interpretation situation by revising his beliefs with his beliefs about what the message sender believes in that situation. If such an account is based on AGM belief revision/contraction(Alchourrón 1985, Gärdenfors 1989)there is a number of well-known problems that need to be addressed, because revision of iterated belief modalities is required in this case. These problems have already been investigated in detail in recent works on DDL Leitgeb/Segerberg 2007)and DEL see e.g. Ditmarsch et. (2008) Another strategy would be to maintain and revise assumptions independently of the beliefs of an agent.I will briefly discuss the advantages and disadvantages of each of these views. In both views, assumptions constitute the subjective context in which an agent interprets an utterance and encounters the world. The result of an interpretation is in turn checked against the agent’s original beliefs, and if the checking operation succeeds the agent revises his beliefs by the result in the normal way described by the AGM paradigm. -/- The second of the above questions needs to be addressed on the basis of concrete examples. Considering utterance like David is ready’ or ‘John is tall’that from a contextualist viewpoint express semantically incomplete content in the sense of Bach(2005, 2007, how may an agent arrive at interpretations of these utterances that are more complete? A first step is to presume that missing semantic ingredients are represented by missing argument places, which is a problematic assumption as it introduces a dependence on the semantic representation language. Given that, a default interpretation can be obtained by existentially quantifying over the missing argument and interpretation can then be regarded as an inference process. In case of the two examples mentioned,the assumptions of the agent allow him to obtain more specific readings by instantiating a value for the existentially bound variable.<span class='Hi'></span> As I will show,<span class='Hi'></span> this inference can be relatively straightforward in some cases like <span class='Hi'></span>‘John is tall’<span class='Hi'></span>, whereas it requires complicated encyclopedic background knowledge and a number of default reasoning steps in other cases.<span class='Hi'></span> -/- Based on more examples of this kind,<span class='Hi'></span> I argue that first,<span class='Hi'></span> belief revision with iterated modalities in a multi-agent setting is needed to generate an agent’s assumptions as laid out above.<span class='Hi'></span> Second,<span class='Hi'></span> default reasoning is needed.<span class='Hi'></span> Third,<span class='Hi'></span> a qualitative or quantitative representation of uncertainty <span class='Hi'></span>(‘degrees of belief’<span class='Hi'></span>) is needed in order to obtain a useful model of the checking step,<span class='Hi'></span> since fortunately not everybody believes everything that other people say.<span class='Hi'></span> These requirements put the theory of interpretation based on assumptions in the frontline of ongoing research on the implementation of belief revision and update in dynamic logics.<span class='Hi'></span> Such a theory might also be useful for contextualist accounts of strong knowledge,<span class='Hi'></span> as it can be argued convincingly that when a knowledge ascription appears to be context-sensitive,<span class='Hi'></span> this is so because the embedded proposition is context-sensitive and not because knowledge itself is context-sensitive.<span class='Hi'></span> Hence,the context-sensitivity of embedded propositions in knowledge claims and how different agents in the same situation arrive at different assessments about them may be explained by an inferential theory of interpretation similar to the one outlined here but with another underlying concept of assumptions.<span class='Hi'></span> -/- Literature <span class='Hi'></span> Alchourrón,<span class='Hi'></span> C.<span class='Hi'></span> E.<span class='Hi'></span>; Gärdenfors,<span class='Hi'></span> P.<span class='Hi'></span> &<span class='Hi'></span> Makinson,<span class='Hi'></span> D.<span class='Hi'></span> (1985)<span class='Hi'></span>, <span class='Hi'></span>'On the logic of theory change:<span class='Hi'></span> partial meet contraction and revision functions'<span class='Hi'></span>, Journal of Symbolic Logic(50)<span class='Hi'></span>, 510-530.<span class='Hi'></span> -/- Bach,<span class='Hi'></span> K.<span class='Hi'></span> (2007)<span class='Hi'></span>, <span class='Hi'></span>'Minimalism for Dummies:<span class='Hi'></span> Reply to Cappelen and Lepore'<span class='Hi'></span>, Technical report,<span class='Hi'></span> University of San Fransisco,<span class='Hi'></span> Department of Philosophy.<span class='Hi'></span> -/- Bach,<span class='Hi'></span> K.<span class='Hi'></span> (2005)<span class='Hi'></span>, Context ex Machina,<span class='Hi'></span> in án Gendler Szabó,<span class='Hi'></span> ed.<span class='Hi'></span>,'Semantics versus Pragmatics'<span class='Hi'></span>, Oxford UP,<span class='Hi'></span> Oxford,<span class='Hi'></span> pp.<span class='Hi'></span> 16-44.<span class='Hi'></span> -/- Ditmarsch,<span class='Hi'></span> H.<span class='Hi'></span> v.<span class='Hi'></span>; Hoek,<span class='Hi'></span> W.<span class='Hi'></span> v.<span class='Hi'></span> d.<span class='Hi'></span> &<span class='Hi'></span> Kooi,<span class='Hi'></span> B.<span class='Hi'></span> (2008)<span class='Hi'></span>, Dynamic Epistemic Logic,<span class='Hi'></span> Kluwer.<span class='Hi'></span> -/- Gärdenfors,<span class='Hi'></span> P.<span class='Hi'></span> (1988)<span class='Hi'></span>, Knowledge in Flux,<span class='Hi'></span> MIT Press.<span class='Hi'></span> -/- Leitgeb,<span class='Hi'></span> H.<span class='Hi'></span> &<span class='Hi'></span> Segerberg,<span class='Hi'></span> K.<span class='Hi'></span> (2007)<span class='Hi'></span>, <span class='Hi'></span>'Dynamic doxastic logic:<span class='Hi'></span> why,<span class='Hi'></span> how,<span class='Hi'></span> and where to?<span class='Hi'></span>',<span class='Hi'></span> Synthese155(2)<span class='Hi'></span>, 167-190.<span class='Hi'></span> -/- Stalnaker,<span class='Hi'></span> R.<span class='Hi'></span> (1978)<span class='Hi'></span>, Assertion,<span class='Hi'></span> in <span class='Hi'></span>.

In this paper I argue that the requirement for the qualitative is theory-dependent, determined by the fundamental assumptions built into the ontology. John Heil’s qualitative, in its role as individuator of objects and powers, is required only by a theory that posits a world of distinct objects or powers. Does Heil’s ‘deep’ view of the world, such that there is only one powerful object (e.g. a field containing modes or properties which we perceive as manifest everyday objects) require the (...) qualitative as individuator of objects and powers? The answer depends on whether it is possible to account for the manifest objects and the ostensible spatial primacy of our perceived world without recourse to the qualitative. In this paper I outline just such an account with the intention of extending Heil’s efforts to incorporate fundamental power in the world while providing a coherent explanation for our strong intuition of spatial, as against relational, priority.

John Searle begins his (1990) ``Consciousness, Explanatory Inversion and Cognitive Science'' with
``Ten years ago in this journal I published an article (Searle, 1980a and 1980b) criticising what I call Strong AI, the view that for a system to have mental states it is sufficient for the system to implement the right sort of program with right inputs and outputs. Strong AI is rather easy to refute and the basic argument can be summarized in one sentence: (...) {it a system, me for example, could implement a program for understanding Chinese, for example, without understanding any Chinese at all.} This idea, when developed, became known as the Chinese Room Argument.''
The Chinese Room Argument can be refuted in one sentence. (shrink)
I argue that John Searle's (1980) influential Chinese room argument (CRA) against computationalism and strong AI survives existing objections, including Block's (1998) internalized systems reply, Fodor's (1991b) deviant causal chain reply, and Hauser's (1997) unconscious content reply. However, a new ``essentialist'' reply I construct shows that the CRA as presented by Searle is an unsound argument that relies on a question-begging appeal to intuition. My diagnosis of the CRA relies on an interpretation of computationalism as a scientific theory (...) about the essential nature of intentional content; such theories often yield non-intuitive results in non-standard cases, and so cannot be judged by such intuitions. However, I further argue that the CRA can be transformed into a potentially valid argument against computationalism simply by reinterpreting it as an indeterminacy argument that shows that computationalism cannot explain the ordinary distinction between semantic content and sheer syntactic manipulation, and thus cannot be an adequate account of content. This conclusion admittedly rests on the arguable but plausible assumption that thought content is interestingly determinate. I conclude that the viability of computationalism and strong AI depends on their addressing the indeterminacy objection, but that it is currently unclear how this objection can be successfully addressed.

To many contemporary philosophers, the phrase “essentialist nominalism” may appear to be an oxymoron. After all, essentialism is the doctrine that things come in natural kinds characterized by their essential properties, on account of some common nature or essence they share. But nominalism is precisely the denial of the existence, indeed, the very possibility of such shared essences. Nevertheless, despite the intuitions of such contemporary philosophers,2 John Buridan was not only a thoroughgoing nominalist, as is well-known, but also a (...) staunch defender of a strong essentialist doctrine against certain skeptics of his time. But then the question inevitably arises: could he consistently maintain such a doctrine? (shrink)
Cet article analyse la manière dont l'engagement moral individuel est traité dans la théorie de la justice de John Rawls. En partant de la distinctionclé entre rationnel et raisonnable, la notion de « conformité » est décomposée en plusieurs strates. A une forme minimale de la conformité s'ajoutent des notions d'adhésion faible et d'adhésion forte. Diverses maximes de comportement individuel sont discutées, qui correspondent à différents degrés d'exigence morale. L'article s'achève sur une réflexion plus large sur le lien entre (...) engagement individuel et tolérance dans la société rawlsienne. This article analyzes the way in which individual moral commitment is treated in John Rawls's theory of justice. It starts with the central distinction between rational and reasonable and divides the notion of « compliance » into several components. Next to a minimal form of compliance, there is a weak form of adhesion and a strong one. Various maxims for individual behavior are discussed, corresponding to various degrees of moral demandingness. The article closes with a broader reflection on the link between moral commitment and tolerance in the Rawlsian society. (shrink)

By using algebraic-categorical tools, we establish four criteria in order to disprove canonicity, strong completeness, w-canonicity and strong w-completeness, respectively, of an intermediate propositional logic. We then apply the second criterion in order to get the following result: all the logics defined by extra-intuitionistic one-variable schemata, except four of them, are not strongly complete. We also apply the fourth criterion in order to prove that the Gabbay-de Jongh logic D1 is not strongly w-complete.
Abstract An examination of John Pollock's theory of artificial intelligence and philosophy of mind raises difficulties for his mechanist concept of person. Token physicalism, agent materialism, and strong artificial intelligence are so related that if the first two propositions are not well?established, then there is no justification for believing that an artificial consciousness can be designed and built. Pollock's arguments are shown to be inconclusive in upholding a functionalist theory of persons as supervenient but purely physical entities. In (...) part this is the result of Pollock's thin definition of the concept of supervenience, according to which any complex supervenes on its proper parts. The limitations of this account are apparent when contrasted with richer conceptions of supervenience, such as Joseph Margolis?. But on Margolis? theory, the mind and its expressions supervene on or rise above their material embodiments in the sense that they cannot be fully explained in physical terms, which contradicts Pollock's token physicalism and agent materialism. The consequence for Pollock's project to explain the mind as mechanical, and to manufacture artificial persons, is that these systems can at best aspire to impressive innovations in weak artificial intelligence, but realistically cannot aspire to strong or mentalistic artificial intelligence.

One of the world's most important philosophers of mind and language, John Searle (b. 1932) is direct, combative, and intellectually ambitious. His philosophy has made fundamental and lasting contributions to how we think about speech, consciousness, knowledge, truth, and the nature of social reality. Here, with remarkable clarity, a leading authority introduces students and generalists to those contributions. Nick Fotion explains Searle's ideas in full, while also testing and exploring their implications. He first takes up Searle's philosophy of language, (...) examining how Searle treats speech acts and thinks about the metaphorical use of language. Next, the book sketches Searle's philosophy of mind, including his claims for intentionality and for the centrality of consciousness. This discussion highlights Searle's argument that the mind possesses a subjective character that materialist explanations (including behaviorism and strong artificial intelligence) cannot contain. The author goes on to look at Searle's later writings on the construction of social reality--work that mounts a sophisticated but plainly stated case against deconstructionist, skeptical, and relativistic accounts. Concluding with general reflections on Searle's position vis-à-vis ontology and epistemology, this book is the first to assess and identify common themes and approaches in the whole range of his extensive thought. In doing so, it presents Searle's extremely influential work for the first time as a coherent philosophy. (shrink)
How to define space-time singularities is a serious problem in general relativity. Schmidt's b-boundary construction was commonly regarded as leading to the best (and very elegant) definition of singularities: space-time is said to be singular if it contains at least one b-incomplete curve. Unfortunately, Bosshard (1976) and Johnson (1977) demonstrated that the b-boundary of the closed Friedman universe consists of the single point. This means that the initial and final singularieties (i.e., the beginning and the end of the Friedman world) (...) coincide. So far no remedy to cure this disaster was known. In the present paper, the author reviews the results obtained by himself and W. Sasin (1994) which clarify the problem. The closed Friedman space-time together with its singularities is not smooth manifold but it turns out to be a structured space which is a strong generalization of the manifold concept. Consequently, if the problem is considered within the correct category, i.e. the category of structured spaces, the patologies dissapear. If one remains within the space-time everything is all right. It is only if one attempts to „touch” the singularity (to extend the differential structure from the inside of space-time to the singularity) when the beginning and the end of the universe coalesce. From the perspective of the Demiurg creating the closed Friedman universe the cosmic history is but a single point. The methodological significance of this result is briefly discussed. (shrink)
In this essay, I explore John Stuart Mill’s theory of government and its application to the issue of health care reform. In particular, I ask whether Mill’s theory of government would justify or condemn the creation of a public health-insurance option. Although Mill’s deep distrust of governmental authority would seem to align him with Republicans, Tea Partiers, libertarians, and others, who cast the public option as a “government takeover” of “our” health care system, I argue that Mill offers good (...) reasons for seriously considering some form of government-operated health insurance. For Mill theorizes government as having a positive as well as a negative role to play in people’s lives, and he explicitly endorses “public options” in different areas of life. According to his theory of government, a public health-insurance option would be just as long as it would meet the following two conditions: (1) it would not invade the “reserved territory” of individual liberty; and (2) “the case of expediency is strong.” I argue that a public option would in fact meet both of these conditions, and that Mill would have likely endorsed it as an effective solution to the current health care crisis in the United States.

This essay defends a strong version of the Humean theory of motivation on which desire is necessary both for motivation and for reasoning that changes our desires. Those who hold that moral judgments are beliefs with intrinsic motivational force need to oppose this view, and many of them have proposed counterexamples to it. Using a novel account of desire, this essay handles the proposed counterexamples in a way that shows the superiority of the Humean theory. The essay addresses the (...) classic objection that the Humean theory cannot explain the feeling of obligation, Stephen Darwall's example of motivationally potent reasoning that is not based on preexisting desires, Thomas Scanlon's criticism that the Humean theory fails to account for the structure and phenomenology of deliberation, and the phenomenon of akrasia as discussed by John Searle. In each case a Humean account explains the data at least as thoroughly as opposing views can, while fitting within a simpler total account of how we deliberate and act. (shrink)
Rawls in his later philosophy claims that it is sufficient to accept political conception as true or right, depending on what one's worldview allows, on the basis of whatever reasons one can muster, given one's worldview (doctrine). What political liberalism is interested in is a practical agreement on the political conception and not in our reasons for accepting it. There are deep issues (regarding deep values, purpose of life, metaphysics etc.) which cannot be resolved through invoking common reasons (this is (...) the fact of free reason itself), and trying to resolve them would involve us in interminable debates and would hamper the practical task of agreement on the political conception. Given the absolute necessity of a political society which is stable and enduring, it is thus wise to avoid these issues in founding a political society and choosing its basic principles - this is the pragmatic part of Rawls's position. In this paper I argue that this strategy leads Rawls into a paradox: (i) although the intention is to stay independent of comprehensive doctrines, the political conception is in fact totally (and precariously) dependent on comprehensive doctrines (not just on one doctrine but on each and every major doctrine in society). It is dependent on them: for its conceptualisation as an independent idea, for its justification, for the check of its reasonability in relation to the external world, for the formation of identities and value inculcation and hence for the formation of its model citizen; (ii) the very search for independence makes the political conception more dependent on comprehensive doctrines, and by extension makes it potentially more prone to intervention in and tampering with comprehensive doctrines (it is enough to show that it is a strong conceptual possibility to cast doubt on the whole strategy). Thus, for example, the political conception relies on the hope that “firmly held convictions gradually change” and that it would “in fact . . . have the capacity to shape those doctrines toward itself”. The purpose of the Rawlsian conjecture is to give these “hopes” a concrete, practical form by giving advice to proponents of the comprehensive doctrine on how they can do all this and “try to show them that, despite what they might think, they can still endorse a reasonable political conception”. I further argue that this paradox can be overcome by making the core of political liberalism more flexible. (shrink)
The author argued elsewhere that a necessary condition that John Fischer and Mark Ravizza offer for moral responsibility is too strong and that the sufficient conditions they offer are too weak.

This paper offers an analysis of a hitherto neglected text on insoluble propositions dating from the late XiVth century and puts it into perspective within the context of the contemporary debate concerning semantic paradoxes. The author of the text is the italian logician Peter of Mantua (d. 1399/1400). The treatise is relevant both from a theoretical and from a historical standpoint. By appealing to a distinction between two senses in which propositions are said to be true, it offers an unusual (...) solution to the paradox, but in a traditional spirit that contrasts a number of trends prevailing in the XiVth century. It also counts as a remarkable piece of evidence for the reconstruction of the reception of English logic in italy, as it is inspired by the views of John Wyclif. Three approaches addressing the Liar paradox (Albert of Saxony, William Heytesbury and a version of strong restrictionism) are first criticised by Peter of Mantua, before he presents his own alternative solution. The latter seems to have a prima facie intuitive justification, but is in fact acceptable only on a very restricted understanding, since its generalisation is subject to the so-called revenge problem.

: This paper discusses critically W.V. Quine's relation to the tradition of pragmatism. Even though Quine is often regarded as a pragmatist, it is far from clear what his commitment to pragmatism actually amounts to. It is argued that while there are pragmatist elements in Quine's position, this is not sufficient to classify him as a pragmatist in any strong historical sense; indeed, he was not even clear himself what it means to be a pragmatist. It is also shown (...) that neither Quine's philosophy nor pragmatism are as anti-metaphysical as has sometimes been thought. In order to enrich the picture of Quine's place in the pragmatist tradition, some neopragmatist criticisms of his ideas (e.g., by Hilary Putnam and Richard Rorty) are also discussed. (shrink)
John McDowell and Bill Brewer famously defend the view that one can only have empirical beliefs if one’s perceptual experiences serve as reasons for such beliefs, where reasons are understood in terms of subject’s reasons. In this paper I show, first, that it is a consequence of the adoption of such a requirement for one to have empirical beliefs that children as old as 3 years of age have to considered as not having genuine empirical beliefs at all. But (...) we have strong reasons to think that 3-year-old children have empirical beliefs, or so I argue. If this is the case, McDowell and Brewer’s requirement for one to have empirical beliefs faces a strong challenge. After showing this, I propose an alternative requirement for one to have empirical beliefs, and argue that it should be favoured over McDowell and Brewer’s requirement. (shrink)
The author defends John R. Searle's Chinese Room argument against a particular objection made by William J. Rapaport called the Korean Room. Foundational issues such as the relationship of strong AI to human mentality and the adequacy of the Turing Test are discussed. Through undertaking a Gedankenexperiment similar to Searle's but which meets new specifications given by Rapaport for an AI system, the author argues that Rapaport's objection to Searle does not stand and that Rapaport's arguments seem convincing (...) only because they assume the foundations of strong AI at the outset.

John Searle claims that social-scientific laws are impossible because social phenomena are physically open-ended. William Butchard and Robert D’Amico have recently argued that, by Searle’s own lights, money is a social phenomena that is physically closed.

Money is not physically open-ended in the (...)strong sense that Butchard and D’Amico require, and their argument for the possibility of social-scientific laws fails as a result. (shrink)
The paper is devoted to the interpretation of one of the most important passages in modern Anglophon philosophy: III.1.3 of Treatise of Human Nature by David Hume. The author considers the problem of its meaning at an angle of the standard interpretation, which can be summed up in a dictum: ‘no ought from is’ (so called “Hume’s Guillotine”). The author outlines four possible approaches to this putative meaning of the Treatise passage and weighs arguments for them. The investigation, based mainly (...) on the strategies by Arthur Prior, Charles Pigden and John Searle, allows to defend two approaches regarding Hume’s putative proposal of is/ought gap: /1/ the idea of logical autonomy of moral discourse, making strong rationality of deduction from is to (non-trivial) ought invalid, together with /2/ the possibility of weak rational (justified) inference from is to ought. However, the comparison of these two accounts with the guts of Humean philosophy as such (critical skepticism, fallibilism, ethical noncognitivism) makes the author prone to give a priority to the latter.

Value-pluralism is commonly held to support liberal political morality. This is argued by John Rawls and his school and, more instructively, by Isaiah Berlin and Joseph Raz. Against this common view it is argued that a strong version of value-pluralism and liberalism are incompatible doctrines. Some varieties of ethical pluralism are distinguished, and the claim of value-incommensurability made by strong pluralism is elucidated. The argument that liberal political morality consists of principles of right that are unaffected by (...) the truth of strong pluralism is examined and rejected. Strong pluralism is understood as the view that some goods and bads are rationally incommensurable. It is argued that if strong value-pluralism is true, then liberal political morality cannot be defended. Neither negative liberty nor individual autonomy can have general priority if it is true that the central goods specified by liberal political morality are incommensurables. This difficulty is not avoided by liberal theories that do not demand the maximization of a single value such as liberty. If strong pluralism is true, then liberal institutions are not a standard of legitimacy by reference to which all regimes are to be assessed. They are merely one variety of modus vivendi . Liberal institutions have no universal legitimacy. Yet liberal cultures are partly constituted by a belief in the universal authority of the principles which inform their practices and institutions. This belief strong pluralism subverts. Value-pluralism and liberalism are rival doctrines. The political implication of strong pluralism is not liberalism but modus vivendi . Sometimes modus vivendi is best fostered by liberal institutions. Sometimes it is best fostered by non-liberal institutions. Where the latter is true, liberals and pluralists part company. (shrink)
In recent work, John McDowell has urged that we resurrect the Kantian thesis that concepts without intuitions are empty. I distinguish two forms of the thesis: a strong form that applies to all concepts and a weak form that is limited to empirical concepts. Because McDowell rejects Kant’s philosophy of mathematics, he can accept only the weaker form of the thesis. But this position is unstable. The reasoning behind McDowell’s insistence that empirical concepts can have content only if (...) they are actualizable in passive experience makes it mysterious how the concepts of pure mathematics can have content. In fact, historically, it was anxiety about the possibility of mathematical content, and not worries about the “Myth of the Given,” that spurred the retreat from Kantian views of empirical content. McDowell owes us some more therapy on this score. (shrink)
In The Public and Its Problems, a classic of social and political philosophy, John Dewey exhibits his strong faith in the potential of human intelligence to solve the public's problems. In his characteristic provocative style, Dewey clarifies the meaning and implications of such concepts as "the public," "the state," "government," and "political democracy." He distinguishes his a posterior reasoning from a priori reasoning, which, he argues permeates less meaningful discussion of basic concepts. Dewey repeatedly demonstrates the interrelationships between (...) fact and theory. (shrink)
G. A. Cohen incisively argued that our judgments of social justice should fit our convictions about how to interact with others in our personal lives. Ironically, the ordinary morality of cooperation invoked in his last book undermines his favored principle of equality, and supports John Rawls' reliance on a relevantly impartial choice promoting appropriate fundamental interests as a basis for distributive standards. His further objections to Rawls' account of distributive justice neglect the role of social relations in establishing the (...) proper scope of that impartiality and the moral force of Rawls' taxonomy of non-ideal societies. In contrast, the powerful evocation of goods of community at the end of Cohen's last book points to a genuine inadequacy. Conscientious fellow-citizens must take account of the impact of their political choices on options for sharing and caring. In finding a proper balance between these goods and competing individualist concerns, the original position is of too little use to sustain Rawls' assessment of his conception of justice as complete. In the face of our strong moral convictions about how to live together, both Cohen's luck egalitarianism and Rawls' barriers between aspirations to community and political choice must give way.

A questionnaire on business ethics was administered to business professionals and to upper-class business ethics students. On eight of the seventeen situations involving ethical dilemmas in business, students were significantly more willing to engage in questionable behavior than were their professional counterparts. Apparently, many students were willing to do whatever was necessary to further their own interests, with little or no regard for fundamental moral principles. Many students and professionals functioned within Lawrence Kohlberg's stage four of moral reasoning, the law (...) and order stage. Individualism and egoism remain strong patterns in the moral reasoning of many professionals, but they influence moral reasoning patterns among students to a much greater degree. (shrink)
The meaning of sustainability is the subject of intense debate among environmental and resource economists. Perhaps no other issue separates more clearly the traditional economic view from the views of most natural scientists. The debate currently focuses on the substitutability between the economy and the environment or between “natural capital” and “manufactured capital”—a debate captured in terms of weak versus strong sustainability. In this article, we examine the various interpretations of these concepts. We conclude that natural science and economic (...) perspectives on sustainability are inconsistent. The market-based Hartwick-Solow “weak sustainability” approach is far removed from both the ecosystem-based “Holling sustainability” and the “strong sustainability” approach of Daly and others. Each of these sustainability criteria implies a specific valuation approach, and thus an ethical position, to support monetary indicators of sustainability such as a green or sustainable Gross Domestic Product (GDP). The conflict between “weak sustainability” and “strong sustainability” is more evident in the context of centralized than decentralized decision making. In particular, firms selling “services” instead of material goods and regarding the latter as “capital” leads to decisions more or less consistent with either type of sustainability. Finally, we discuss the implications of global sustainability for such open systems as regions and countries. Open systems have not been dealt with systematically for any of the sustainability criteria. (shrink)

The view that decision methods can only be justified by appeal to pragmatic considerations is defended. Pragmatic considerations are viewed as providing the underlying subject matter (“semantics”) of decision theories. It is argued that other approaches (e.g. justifying principles by appeal to obviousness, common usage, etc.) fail to provide grounds for a normative decision theory.It is argued that preferences that can lead to pragmatically adverse outcomes in a relevantly similar possible decision situation are pragmatically unsound, even if the decision situation (...) never arises. This rebuts several standard objections to money-pump and Dutch book arguments. However, because one can only appeal to relevantly similar decision situations in pragmatic arguments, these will have a less general scope than is often imagined. A conclusion is that pragmatic arguments for strong unconditional principles such as ‘always maximise expected utility!’ do not work. Pragmatic considerations can however be used to argue for conditional principles of the form ‘if conditions X, Y and Z are satisfied, then one ought to satisfy W’, where W need not follow logically from X, Y and Z.The notion of a sound pragmatic argument is defined in terms of particular notion of coherence, it is shown how this can be applied and how it handles problematic cases such as van Fraassen’s Dutch book for the principle of Reflection.

The method of strong inference, wherein multiple hypotheses are constructed and a crucial experiment is carried out, is said to have special status in science because it guarantees falsifying results. However, the proposition that strong inference is in any way superior to the method of constructing and testing a single hypothesis is contradicted both by close rational analysis and by the empirical evidence. An experiment is reviewed in which subjects who conduct strong tests are much less likely (...) to discover or approximate the truth than subjects who conduct simple tests of a false hypothesis. It is concluded that a potential to falsify is necessary for a test to have corroborative value; however, arguments as to the general superiority of one type of potentially falsifying test over another have no logical basis. Any claim as to a general superiority of strong tests over simple tests would require access to information about the probability of each strategy to produce various relationships between the truth and whatever explanations are most accessible, and such information is not knowable, even in principle.

Can a supercompact cardinal κ be Laver indestructible when there is a level-by-level agreement between strong compactness and supercompactness? In this article, we show that if there is a sufficiently large cardinal above κ, then no, it cannot. Conversely, if one weakens the requirement either by demanding less indestructibility, such as requiring only indestructibility by stratified posets, or less level-by-level agreement, such as requiring it only on measure one sets, then yes, it can.
Abstract This paper discusses possibilities of ethical perception, and draws a strong contrast between traditional rationally?based views, and more recent theories involving both narrative and feminist ethical points of view. I argue that these two latter categories share more conceptually than is usually acknowledged, add to this the possibility that some theories of aesthetic perception bear similarity to points of the non?rational moral theories, and discuss whether this similarity is organic or incidental. The finding of structural similarity lends support (...) to writings both of John Dewey and of major poets arguing for the relationship between aesthetic and ethical sensibilities, and to the function of the arts as morally illuminating, not prescriptive. This relationship is explored as it occurs in the subculture of our youth, both in and out of school, and findings are drawn relevant to curriculum design both within and beyond what is conventionally considered moral education.

Duiker, John It has been suggested that the global proliferation of the Catholic Charismatic Renewal (CCR) is a metonymic sign that directly manifests and points to the creative activity of the Creator in history, and that being an enchanted phenomenon it can stand as an example for the re-enchantment of a post-Enlightenment secular world.1 These appear to be strong claims for an ecclesial movement of the Church, and in order to ascertain the validity of such statements, it is (...) necessary to undertake a journey into the development and understanding of the movement itself. Our steps on the journey that will assist in the validation of such claims will locate the CCR within a cultural context, reflect on its history and origins, its christological and pneumatological character, explain its relationship to the sacramental economy and broader church, and identify its characteristics, fruits and its more specific place in the Australian church. This study will also provide an opportunity to gain a further appreciation of a movement that has touched the lives of millions of people. (shrink)
In this paper, two theorems concerning measurable limits of strong cardinals and supercompactness are proven. This generalizes earlier work, both individual and joint with Shelah.
Question: What is a (or the) scientific theory V based on a set B of syntactical L-formulas, interpreted according to the intended interpretations of the language L? What probably corresponds to the traditional candidate for V is found to be inadequate for use in deductively explaining experimental facts of a certain form. A second candidate for V, called a strong scientific theory (SST), does not suffer such an inadequacy because it is existentially strong, i.e., it has considerable existential (...) import. It even satisfies the particle physicist's dictum: WHAT IS NOT FORBIDDEN WILL HAPPEN. (shrink)
Eschewing talk about a strong or weak will, I view the will of the dieter to be essentially identical to that of the normal eater, and say they differ only in the luck of their circumstances. However, I adopt a compatibilist approach to the will, generally, such that the dieter, despite having unlucky circumstances, is responsible for her efforts to lose weight. I base this on Hook's view that a person does not know what she can do before doing (...) it, and that she can "redetermine the direction of events" through effort. But a model of "redetermining" the will in which this is a conscious activity is insufficient to address the dieter's problem. I advocate consideration of another dimension of experience, based on the psychoanalytic theory of D.W. Winnicott, in which creative insight arises from the unconscious true self. I suggest that creative insight bypasses the will to radically change the dieter's perspective in a way that conscious strategies alone cannot achieve. I conclude that freedom is possible on the basis of conscious willing and in tapping the unconscious true self. (shrink)
We prove, relative to suitable hypotheses, that it is consistent for there to be unboundedly many measurable cardinals each of which possesses a large degree of strong compactness, and that it is consistent to assume that the least measurable is partially strongly compact and that the second measurable is strongly compact. These results partially answer questions of Magidor on the relationship of strong compactness to measurability.
Combining techniques of the first author and Shelah with ideas of Magidor, we show how to get a model in which, for fixed but arbitrary finite n, the first n strongly compact cardinals κ 1 ,..., κ n are so that κ i for i = 1,..., n is both the i th measurable cardinal and κ + i supercompact. This generalizes an unpublished theorem of Magidor and answers a question of Apter and Shelah.
We construct a model in which there is a strongly compact cardinal κ such that the set $S(\kappa,\kappa ^{+})=\{a\in P_{\kappa}\kappa ^{-}\colon o,t(a)=(a\cap \kappa)^{+}\})$ is non-stationary.
The idea that a computer could be conscious--or equivalently, that human consciousness is the effect of some complex computation mechanically performed by our brains--strikes some scientists and philosophers as a beautiful idea. They find it initially surprising and unsettling, as all beautiful ideas are, but the inevitable culmination of the scientific advances that have gradually demystified and unified the material world. The ideologues of Artificial Intelligence (AI) have been its most articulate supporters. To others, this idea is deeply repellent: philistine, (...) reductionistic (in some bad sense), as incredible as it is offensive. John Searle's attack on "strong AI" is the best known expression of this view, but others in the same camp, liking Searle's destination better than his route, would dearly love to see a principled, scientific argument showing that strong AI is impossible. Roger Penrose has set out to provide just such an argument. (shrink)
John Searle's Chinese room argument is perhaps the most influential andwidely cited argument against artificial intelligence (AI). Understood astargeting AI proper â claims that computers can think or do thinkâ Searle's argument, despite its rhetorical flash, is logically andscientifically a dud. Advertised as effective against AI proper, theargument, in its main outlines, is an ignoratio elenchi. It musterspersuasive force fallaciously by indirection fostered by equivocaldeployment of the phrase "strong AI" and reinforced by equivocation on thephrase "causal powers" (at (...) least) equal to those of brains." On a morecarefully crafted understanding â understood just to targetmetaphysical identification of thought with computation ("Functionalism"or "Computationalism") and not AI proper the argument is still unsound,though more interestingly so. It's unsound in ways difficult for high churchâ "someday my prince of an AI program will come" â believersin AI to acknowledge without undermining their high church beliefs. The adhominem bite of Searle's argument against the high church persuasions of somany cognitive scientists, I suggest, largely explains the undeserved reputethis really quite disreputable argument enjoys among them.

In this dissertation on Hilary Putnam's philosophy, I investigate his development regarding meaning and necessity, in particular mathematical necessity. Putnam has been a leading American philosopher since the end of the 1950s, becoming famous in the 1960s within the school of analytic philosophy, associated in particular with the philosophy of science and the philosophy of language. Under the influence of W.V. Quine, Putnam challenged the logical positivism/empiricism that had become strong in America after World War II, with influential exponents (...) such as Rudolf Carnap and Hans Reichenbach. Putnam agreed with Quine that there are no absolute a priori truths. In particular, he was critical of the notion of truth by convention. Instead he developed a notion of relative a priori truth, that is, a notion of necessary truth with respect to a body of knowledge, or a conceptual scheme. Putnam's position on necessity has developed over the years and has always been connected to his important contributions to the philosophy of meaning. I study Hilary Putnam's development through an early phase of scientific realism, a middle phase of internal realism, and his later position of a natural or commonsense realism. I challenge some of Putnam’s ideas on mathematical necessity, although I have largely defended his views against some other contemporary major philosophers; for instance, I defend his conceptual relativism, his conceptual pluralism, as well as his analysis of the realism/anti-realism debate.

Several scholars and many religiously conservative thinkers have recently charged that Hitler’s ideas about race and racial struggle derived from the theories of Charles Darwin (1809-1882), either directly or through intermediate sources. So, for example, the historian Richard Weikart, in his book From Darwin to Hitler , maintains: “No matter how crooked the road was from Darwin to Hitler, clearly Darwinism and eugenics smoothed the path for Nazi ideology, especially for the Nazi stress on expansion, war, racial struggle, and racial (...) extermination.” In a subsequent book, Hitler’s Ethic: The Nazi Pursuit of Evolutionary Progress, Weikart argues that Darwin’s “evolutionary ethics drove him [Hitler] to engage in behavior that the rest of us consider abominable.” Other critics have also attempted to forge a strong link between Darwin’s theory and Hitler’s biological notions. In the 2008 film “Expelled,” a documentary defense of Intelligent Design, the Princeton trained philosopher David Berlinski, in conversation with Weikart, confidently asserts: “If you open Mein Kampf and read it, especially if you can read it in German, the correspondence between Darwinian ideas and Nazi ideas just leaps from the page.” John Gray, former professor at the London School of Economics, does allow that Hitler’s Darwinism was “vulgar.” Hannah Arendt also appears to have endorsed the connection when she declared: “Underlying the Nazis’ belief in race laws as the expression of the law of nature in man, is Darwin’s idea of man as the product of a natural development which does not necessarily stop with the present species of human being.” Put “Darwin” and “Hitler” in a search engine and several million hits will be returned, most from religiously and politically conservative websites, articles, and books.

The two theories that revolutionized physics in the twentieth century, relativity and quantum mechanics, are full of predictions that defy common sense. Recently, we used three such paradoxical ideas to prove “The Free Will Theorem” (strengthened here), which is the culmination of a series of theorems about quantum mechanics that began in the 1960s. It asserts, roughly, that if indeed we humans have free will, then elementary particles already have their own small share of this valuable commodity. More precisely, if (...) the experimenter can freely choose the directions in which to orient his apparatus in a certain measurement, then the particle’s response (to be pedantic—the universe’s response near the particle) is not determined by the entire previous history of the universe. Our argument combines the well-known consequence of relativity theory, that the time order of space-like separated events is not absolute, with the EPR paradox discovered by Einstein, Podolsky, and Rosen in 1935, and the Kochen-Specker Paradox of 1967 (See [2].) We follow Bohm in using a spin version of EPR and Peres in using his set of 33 directions, rather than the original configuration used by Kochen and Specker. More contentiously, the argument also involves the notion of free will, but we postpone further discussion of this to the last section of the article. Note that our proof does not mention “probabilities” or the “states” that determine them, which is.. (shrink)

All modern liberal democracies have strong reasons to support an idea of toleration, understood as involving respect, not only grudging acceptance, and to extend it to all religious and secular doctrines, limiting only conduct that violates the rights of other citizens. There is no modern democracy, however, in which toleration of this sort is a stable achievement. Why is toleration, attractive in principle, so difficult to achieve? The normative case for toleration was well articulated by John Locke in (...) his influential A Letter Concerning Toleration , although his attractive proposal thus rests on a fragile foundation. Kant did much more, combining a Lockean account of the state with a profound diagnosis of ‘radical evil’, the tendencies in all human beings to militate against stable toleration and respect. But Kant proposed no mechanism through which the state might mitigate the harmful influence of ‘radical evil’, thus rendering toleration stable. One solution to this problem was proposed by Rousseau, but it has deep problems. How, then, can a respectful pluralistic society shore up the fragile human basis of toleration, especially in a world in which we need to cultivate toleration not only within each state, but also among peoples and states, in this interlocking world? Key Words: toleration • emotion • evil • liberal democracy • Locke • Mill • Kant • Rousseau. (shrink)
I develop an approach to action and practical deliberation according to which the degree of epistemic warrant required for practical rationality varies with practical context. In some contexts of practical deliberation, very strong warrant is called for. In others, less will do. I set forth a warrant account, (WA), that captures this idea. I develop and defend (WA) by arguing that it is more promising than a competing knowledge account of action due to John Hawthorne and Jason Stanley. (...) I argue that cases of warranted false belief speak in favor of (WA) and against the knowledge account. Moreover, I note some problems with an “excuse maneuver” that proponents of the knowledge account frequently invoke in response to cases of warranted false belief. Finally, I argue that (WA) may provide a strict invariantist account of cases that have been thought to motivate interest-relative or subject-sensitive theories of knowledge and warrant. (shrink)
When Alexander Nehamas’s path-breaking, elegantly conceived and executed book, Nietzsche: Life as Literature, first appeared in 1985, the reception of Nietzsche in the Anglo-American philosophical community was still in its initial, hesitant stages, even after the relative success of Walter Kauffmann’s much earlier, 1950 book, Nietzsche: Philosopher, Psychologist, Anti-Christ, and its postwar “decontamination” of Nietzsche after his appropriation by the Nazis.1 Arthur Danto’s 1964 book, Nietzsche as Philosopher, was also an important if somewhat isolated event, and there finally began to (...) appear in the seventies less well known but high quality secondary literature, like John Wilcox’s 1974 book, Truth and Value in Nietzsche, and Tracy Strong’s 1975 book on Nietzsche and politics, Friedrich Nietzsche and the Politics of Transfiguration. And when the Routledge “Arguments of the Philosophers” series brought out Richard Schacht’s lengthy 1983 book Nietzsche, the idea that Nietzsche, whatever else he was doing in his books, was making philosophical claims and devising ways to defend them, was becoming more firmly established. Many of the most successful aspects of Nehamas’s interpretation (essentially Part One of the book) spoke to what was still the early resistance to any philosophical attention to Nietzsche: the facile insistence that his “persepectivism” was a self-refuting relativism, that his attack on truth and the value of..

There are various proposals for a general characterization of holism1. In this paper I propose the following: a variety of holism is the view that every X of an appropriate kind, which is part of a relevant whole W, cannot be legitimately separated or taken in isolation from W. Then, I distinguish two general kinds of holism, depending on two different reasons which can debar us from taking X in isolation from W. One reason can be that separating X from (...) W always amounts to transforming X into something else. Correspondingly, a strong holism is the view that if the whole W is modified anywhere, X ceases to be X and becomes something else. Another reason why it may be illegitimate to consider X in isolation from W can be that if we separate X from W, nothing that we know entitles us to exclude that X might be transformed into something else. Correspondingly, virtual holism is the view that if the whole W is modified anywhere, we can never rule out that X ceases to be X and becomes something else. (shrink)
John Rawls famously claims that ‘justice is the first virtue of social institutions’. On one of its readings, this remark seems to suggest that social institutions are essential for obligations of justice to arise. The spirit of this interpretation has recently sparked a new debate about the grounds of justice. What are the conditions that generate principles of distributive justice? I am interested in a specific version of this question. What conditions generate egalitarian principles of distributive justice and give (...) rise to equality as a demand of justice? My paper focuses on relationalist answers to this question. Advocates of relationalism assume that ‘principles of distributive justice have a relational basis’, in the sense that ‘practice mediated relations in which individuals stand condition the content, scope and justification of those principles’. To say that principles of justice are ‘based’ on and ‘conditioned’ by practice mediated relations is ambiguous. I will here be concerned with advocates of what I call the relationalist requirement , viz. positions which assume that ‘practice mediated relations’ constitute a necessary existence condition for principles of egalitarian distributive justice. Relationalists who endorse this view come in different varieties. My focus is on relationalists that view social and political institutions as the relevant ‘practice mediated relation’. The question at stake, then, is this: Are institutionally mediated relations a necessary condition for equality to arise as a demand of justice? Strong relationalists of the institutionalist cast, call them advocates of the institutionalist requirement , differ in important respects. They argue about what set of institutions is foundationally significant, and they disagree on why only that institutional relation gives rise to egalitarian obligations of justice. My paper engages two ways of arguing for the institutionalist requirement : Julius’s framing argument and Andrea Sangiovanni’s reciprocity argument . The issue at stake are the grounds of egalitarian justice and I will argue that the institutionalist requirement is mistaken. It is not the case that egalitarian obligations of distributive justice arise only between and solely in virtue of individuals sharing a common institution. (shrink)
Our paper ‘A new cosmological argument’ gave an argument for the existence of God making use of the weak Principle of Sufficient Reason (W-PSR) which states that for every proposition p, if p is true, then it is possible that there is an explanation for p. Recently, Graham Oppy, as well as Kevin Davey and Rob Clifton, have criticized the argument. We reply to these criticisms. The most interesting kind of criticism in both papers alleges that the W-PSR can be (...) justifiably denied by the atheist, and constitutes no improvement on the strong Principle of Sufficient Reason (S-PSR) which claims that every true proposition in fact has an explanation. The criticism is predicated on the fact that it can be shown that the W-PSR entails the S-PSR. We argue that the W-PSR's plausibility remains despite the criticisms. From this it can be seen to follow that the entailment relation between the W-PSR and the S-PSR gives one reason to believe the S-PSR. (shrink)

While there is much common ground between the writings of Amartya Sen and John Stuart Mill – particularly in their advocacy of freedom and gender equality – one is a critic, while the other is an advocate, of utilitarianism. In spite of this contrast, there are strong echoes of Sen's capability approach in Mill's writings. Inasmuch as Mill sees the capability to be happy as important he holds a form of capability approach. He also thinks of happiness as (...) constituted by the exercise of certain capabilities (including the higher faculties). Furthermore, Mill addresses the possibility that people can adapt to limited opportunity, which is central to Sen's critique of some ‘utility’-based views. By contrasting contentment and happiness Mill suggests one way in which a utilitarian might address cases of adaptation. His discussions of capabilities and of adaptation are consistent with his utilitarianism. (Published Online February 16 2006). (shrink)

John R. Searle's problem of the Chinese Room poses an important philosophical challenge to the foundations of strong artificial intelligence, and functionalist, cognitivist, and computationalist theories of mind. Searle has recently responded to three categories of criticisms of the Chinese Room and the consequences he attempts to conclude from it, redescribing the essential features of the problem, and offering new arguments about the syntax-semantics gap it is intended to demonstrate. Despite Searle's defense, the Chinese Room remains ineffective as (...) a counterexample, and poses no real threat to artificial intelligence or mechanist philosophy of mind. The thesis that intentionality is a primitive irreducible relation exemplified by biological phenomena is preferred in opposition to Searle's contrary claim that intentionality is a biological phenomenon exhibiting abstract properties.

Proclus (c.412-485) once offered an argument that Christians took to stand against the Christian doctrine of creation ex nihilo based on the eternity of the world and God’s perfection. John Philoponus (c.490-570) objected to this on various grounds. Part of this discussion can shed light on contemporary issues in philosophical theology on divine perfection and creation. First I will examine Proclus’ dilemma and John Philoponus’ response. I will argue that Philoponus’ fails to rebut Proclus’ dilemma. The problem is (...) that presentism is incompatible with divine simplicity, timelessness, and a strong doctrine of immutability. From there I will look at how this discussion bears on contemporary understandings of divine perfection and creation, and argue that there are at least two possible ways contemporary philosophical theologians can try to get around the dilemma. One option is to adopt four-dimensional eternalism and maintain the traditional account of the divine perfections. I argue that this option suffers from difficulties that are not compatible with Christian belief. The other option is to keep presentism and modify the divine perfections. I argue that this option is possible and preferable since our understanding of the divine perfections must be modified in light of divine revelation and the incarnation. (shrink)
Utilitarianism and its principal architect, John Stuart Mill, are staples of media ethics teaching and analysis. However, utilitarianism, in its usual presentation, is offered as a simplistic arithmetic formula: Do the greatest good for the greatest number. This quantification approach, when attached to Mill, misinterprets this philosopher and robs media ethics discussions of the rich reflection that an important classical theory can bring. Mill is a particularly suitable philosopher for presentation to students of journalism and mass communication. Mill provides (...) a strong argument in favor of freedom of expression in addition to espousing a moral theory that is simultaneously protective of individual rights while promoting communitarian principles. But it is imperative to get Mill right. This essay attempts to do so and to offer a utilitarian decision tree for those who wish to properly apply Mill's theory in teaching and practice. (shrink)
We consider a version of so called T × W logic for historical necessity in the sense of R.H. Thomason (1984), which is somewhat special in three respects: (i) it is explicitly based on two-dimensional modal logic in the sense of Segerberg (1973); (ii) for reasons of applicability to interesting fields of philosophical logic, it conceives of time as being discrete and finite in the sense of having a beginning and an end; and (iii) it utilizes the technique of systematic (...) frame constants in order to handle the problem of irreflexivity in tense logics, well known since Gabbay (1981). Axiomatizations are given for two infinite hierarchies of two-dimensional modal tense logics, one without and one with the characteristic operators for historical necessity and possibility. Strong and weak completeness results are obtained for both hierarchies as well as a result to the effect that two approaches to their semantics are equivalent, much in the spirit of Di Maio and Zanardo (1996) and von Kutschera (1997).

The central question in political philosophy is whether political states have the right to coerce their constituents and whether citizens have a moral duty to obey the commands of their state. Christopher Heath Wellman and A. John Simmons defend opposing answers to this question. Wellman bases his argument on samaritan obligations to perform easy rescues, arguing that each of us has a moral duty to obey the law as his or her fair share of the communal samaritan chore of (...) rescuing our compatriots from the perils of the state of nature. Simmons counters that this, and all other attempts to explain our duty to obey the law, fail. He defends a position of philosophical anarchism, the view that no existing state is legitimate and that there is no strong moral presumption in favor of obedience to, or compliance with, any existing state.

The Chinese room argument is a thought experiment of John Searle (1980a) and associated (1984) derivation. It is one of the best known and widely credited counters to claims of artificial intelligence (AI)—that is, to claims that computers do or at least can (someday might) think. According to Searle’s original presentation, the argument is based on two key claims: brains cause minds and syntax doesn’t suffice for semantics. Its target is what Searle dubs “strong AI.” According to (...) class='Hi'>strong AI, Searle says, “the computer is not merely a tool in the study of the mind, rather the appropriately programmed computer really is a mind in the sense that computers given the right programs can be literally said to understand and have other cognitive states” (1980a, p. 417). Searle contrasts strong AI with “weak AI.” According to weak AI, computers just simulate thought, their seeming understanding isn’t real understanding (just as-if), their seeming calculation is only as-if calculation, etc. Nevertheless, computer simulation is useful for studying the mind (as for studying the weather and other things).

A critique of several recent objections to John Searle's Chinese-Room Argument against the possibility of "strong AI" is presented. The objections are found to miss the point, and a stronger argument against Searle is presented, based on a distinction between "syntactic" and "semantic" understanding.
This article offers a critical review of various ontological-relativist arguments, mostly deriving from the work of W. V. Quine and Thomas K hn. I maintain that these arguments are (1) internally contradictory, (2) incapable of accounting for our knowledge of the growth of scientific knowledge, and (3) shown up as fallacious from the standpoint of a causal-realist approach to issues of truth, meaning, and interpretation. Moreover, they have often been viewed as lending support to such programmes as the 'strong' (...) sociology of knowledge and the turn towards wholesale cultural-relativist doctrines, whether of the Wittgensteinian ('language-games') or Heideggerian (depth-hermeneutic) varieties. Thus Richard Rorty recommends that we should henceforth drop all that old-fashioned talk of 'truth', 'knowledge', or 'reality', since whatever warrants those descriptions from time to time is just the product of some currently favoured language-game or range of elective metaphors. Such ideas have little in common with Quine's general outlook of robust physicalism, nor again - though the case is less clear - with Kuhn's reconsidered approach to these issues as set forth in his 1969 Postscript to The Structure of Scientific Revolutions . However, both thinkers have left themselves open to misconstrual by adopting a sceptical-relativist fallback position in response to the well-known problems with logical empiricism. This essay therefore reviews those problems with reference to alternative, more adequate accounts of what is involved in the process of scientific discovery and theory-change. (shrink)
In his book, Contemporary Theories of Knowledge, John Pollock argues that all externalist theories of justification should be rejected on the grounds that they do not do justice to the action-guiding character of epistemic norms. I reply that Pollocks argument is ineffective — because not all externalisms are intended to involve action-guiding norms, and because Pollock does not give a good reason for thinking that action-guiding norms must be internalist norms. Second, I consider rehabilitating Pollocks argument by restricting his (...) conclusion to theories that do involve action-guiding norms and providing a better reason to think that action-guiding norms must be internalist norms. But I claim that if Pollocks argument is made strong enough to rule out all externalisms, it rules out too much, namely, any plausible conception of epistemic norms. (shrink)
What''s computation? The received answer is that computation is a computer at work, and a computer at work is that which can be modelled as a Turing machine at work. Unfortunately, as John Searle has recently argued, and as others have agreed, the received answer appears to imply that AI and Cog Sci are a royal waste of time. The argument here is alarmingly simple: AI and Cog Sci (of the Strong sort, anyway) are committed to the view (...) that cognition is computation (or brains are computers); butall processes are computations (orall physical things are computers); so AI and Cog Sci are positively silly.I refute this argument herein, in part by defining the locutions x is a computer and c is a computation in a way that blocks Searle''s argument but exploits the hard-to-deny link between What''s Computation? and the theory of computation. However, I also provide, at the end of this essay, an argument which, it seems to me, implies not that AI and Cog Sci are silly, but that they''re based on a form of computation that is well beneath human persons.

Francis Hutcheson’s theory of value is often characterized as a precursor to the qualitative hedonism of John Stuart Mill. The interpretation of Mill as a qualitative hedonist has come under fire recently; some have argued that he is, in fact, a hedonist of no variety at all.1 Others have argued that his hedonism is as non-qualitative as Bentham’s.2 The purpose of this essay is not to critically engage the various interpretations of Mill’s value theory. Rather, I hope to show (...) that Hutcheson should not be read as a qualitative hedonist. The evidence for Hutcheson as a qualitative hedonist is strong and striking. The most commonly cited passages are taken from his posthumous opus, A System of Moral .. (shrink)
It has been claimed in several places that the new genetic technologies allow humanity to achieve in a generation or two what might take natural selection hundreds of millennia in respect of the elimination of certain diseases and an increase in traits such as intelligence. More radically, it has been suggested that those same technologies could be used to instil characteristics that we might reasonably expect never to appear due to natural selection alone. John Harris, a proponent of this (...) genomic optimism, claims in his book Enhancing Evolution that we not only have it in our power to enhance evolution, but that we also have a duty to do so. In this paper, I claim that Harris' hand is strong but that he overplays it nevertheless. He is correct to dismiss the arguments of the anti-enhancement lobby and correct to say that enhancement is permissible; but ‘good’ is different from ‘permissible’ and his argument for the goodness of enhancement is less convincing. Moreover, he is simply wrong to claim that it generates a duty to enhance. (shrink)
Patrick Shade makes a strong argument for the necessity of hope in a cynical world that too often rejects it as foolish. While most accounts of hope situate it in a theological context, Shade presents a theory rooted in the pragmatic thought of such American philosophers as C. S. Peirce, William James, and John Dewey.
