Since we explain behavior by ascribing intentional states to the agent, many philosophers have assumed that some guiding principle of folk psychology like [Intentional States and Actions] must be true. [Intentional States and Actions]: If A and B are different actions, then the agents performing them must differ in their intentional states at the time they are performed. Recent results in the physiology of vision present a prima facie problem for this principle. These results show that some visual information that (...) guides spatial manipulation and fine motor control is unavailable for verbal report. Plausibly, this information is not consciously available to the agent, and as such, not available to inform the content of intentional states. Thus, it is hard to see how every difference in action is subject to intentional explanation, as [Intentional States and Actions] requires. I articulate the prima facie problem and argue that the most plausible solution requires us to reject [Intentional States and Actions]. (shrink)

The Russellian approach to the semantics of attitude ascriptions faces a problem in explaining the robust speaker intuitions that it does not predict. A familiar response to the problem is to claim that utterances of attitude ascriptions may differ in their Gricean conversational implicatures. I argue that the appeal to Grice is ad hoc. First, we find that speakers do not typically judge an utterance false merely because it implicates something false. The apparent cancellability of the putative implicatures is irrelevant, (...) since cancellability does not indicate conversational implicature. Finally, the appeal assumes, implausibly, that ordinary speakers generally subscribe to a particular philosophical theory about belief. (shrink)

Some time ago, John Perry argued that the content of an indexical belief, that is, a belief expressible with a sentence containing an indexical or demonstrative, cannot be a proposition. I consider several of his arguments for this view, and show that they can be extended to show that belief expressible with other non-indexical expressions such as natural kind terms and proper names presents the very same problem for the traditional picture. I then suggest that if indexical belief has any (...) special status, this is not because it has a special kind of content, but rather because action is impossible if agents do not have indexical belief.

In Propositional Attitudes, Mark Richard claims that some natural and formal language sentences of the form(∀ x)(∀ y)(x = y → α → α [y/x])are false. He suggests a substitution for α that is sensitive to certain ancillary features of the variable letter as well as the assignment, and then argues that this substitution generates a false instance of the above-mentioned schema. I reject Richard's argument and argue further that the sentence is not an instance of that schema. I then (...) argue that his putative natural language example fails as well. Finally, I suggest that although Richard's mistake here does not present any technical problem for his semantics for attitude ascriptions, it undermines his claim that his semantic theory is better able to respect the surface form of attitude ascriptions in natural languages than competing theories.

A familiar story about phenomenal knowledge likens it to indexical knowledge, i.e. knowledge about oneself typically expressed with sentences containing indexicals or demonstratives. The popularity of this sort of story owes in part to its promise of resolving some longstanding puzzles about phenomenal knowledge. One such puzzle arises from the compelling arguments that we can have full objective knowledge of the world while lacking some phenomenal knowledge. I argue that the widespread optimism about the indexical account on this score is (...) unwarranted. (shrink)

There is a traditional picture of belief, according to which someone's having a belief is that person's standing in a certain relation to an abstract object, a proposition. My dissertation examines the metaphysical demands that two problems for this picture of belief make on these abstract objects. The first problem comes to us from Frege's "On Sense and Reference," and the second concerns a certain sort of one's beliefs about oneself, which I call "indexical beliefs." ;Frege notes that someone can (...) believe that Hesperus is Hesperus without believing that Hesperus is Phosphorus. It is but a short step from Frege's observation to the claim that the sentence "A believes that Hesperus is Hesperus" could be true while "A believes that Hesperus is Phosphorus" is false. Quine has insisted that we cannot address this problem by taking either of these sentences to express a predication of the referent of both names, the planet Venus, as then both sentences would express the same predication of the same object, and this stands in evident tension with the fact that they can differ in truth value. In a recent response to Frege's problem, Mark Richard has taken exactly the route Quine has warned against. In my first chapter, I show that Richard's response is unsuccessful. I then consider the implications of the failure of his response on his proposed semantics for belief and the philosophical motivation he provides for it. I argue that his semantics for belief ascriptions stands in serious tension with its purported philosophical motivation. ;In the second and third chapters, I turn to the problem about indexical belief. The task of the second chapter is to identify this problem. To this end, I consider three of John Perry's arguments that the traditional picture of belief cannot accommodate indexical belief. I show that even if these arguments are sound, they give us no reason to think that the problem about indexical belief is in any way unique. I then suggest that there is a special problem about indexical belief, despite the failure of these three arguments to isolate it. Special difficulties attend an account of what it is to retain a tensed belief over time, and I suggest that the special problem about indexical belief is, in brief, a generalization of this problem about retention of tensed belief. ;In the third chapter, I raise the problem about indexical belief in a new way, as arising from a tension between several intuitively plausible claims about the relationship between beliefs and desires, on the one hand, and actions, on the other. This presentation of the problem brings out how the problem is special. I survey several solutions to this problem, including one due to Perry. I then argue that Perry's solution cannot characterize the specific kind of similarity between the beliefs of two different people who share an indexical belief. It allows too much to count as shared indexical belief. Thus Perry's solution inadequately addresses what I have suggested is the unique problem about indexical belief. Finally, I suggest that Frege's response to the problem I raise points the way towards an emendation of Perry's account that will enable it to suitably characterize the special way in which different people can share an indexical belief.

The semantics of belief reports has recently received a great deal of attention. Speech reports have largely been left behind in this discussion. Here I extend a familiar recent account of attitude reports, the Russellian theory, to the special case of speech reports. I then consider how it compares to Davidson’s paratactic theory with respect to a few examples that raise special problems about speech reports. Neither theory accounts for everything we want to say about these cases. I suggest that (...) the problem lies in an assumption common to both theories, that in reporting what others say, we aim to represent what was said exactly as the original speaker represented it, in so far as this is possible.

In this paper, I take issue with the familiar view that the problem of the essential indexical is a merely technical problem, which can be solved through a straightforward revision of the familiar model of belief content. (The familiar model just says that the content of belief is a proposition.) I do not object to these technical fixes, but I think they leave some questions unanswered. Specifically, they deny us an attractive account of what it is for different people to (...) completely agree on their conception of what the world is like, according to which complete agreement consists in having beliefs with the same propositional content, but they do not give us anything to replace it with. Here, I consider whether we can say anything general about the relation between my beliefs and your beliefs (including, of course, our indexical beliefs), when you and I completely agree about what the world is like.

Two-dimensional semantics is a framework that helps us better understand some of the most fundamental issues in philosophy: those having to do with the relationship between the meaning of words, the way the world is, and our knowledge of the meaning of words. This selection of new essays by some of the world's leading authorities in this field sheds fresh light both on foundational issues regarding two-dimensional semantics and on its specific applications.

Predictive genetic testing is now routinely offered to asymptomatic adults at risk for genetic disease. However, testing of minors at risk for adult-onset conditions, where no treatment or preventive intervention exists, has evoked greater controversy and inspired a debate spanning two decades. This review aims to provide a detailed longitudinal analysis and concludes by examining the debate's current status and prospects for the future. Fifty-three relevant theoretical papers published between 1990 and December 2010 were identified, and interpretative content analysis was (...) employed to catalogue discrete arguments within these papers. Novel conclusions were drawn from this review. While the debate's first voices were raised in opposition of testing and their arguments have retained currency over many years, arguments in favour of testing, which appeared sporadically at first, have gained momentum more recently. Most arguments on both sides are testable empirical claims, so far untested, rather than abstract ethical or philosophical positions. The dispute, therein, lies not so much in whether minors should be permitted to access predictive genetic testing but whether these empirical claims on the relative benefits or harms of testing should be assessed.

The world is said to contain crystal balls whenever the present carries news of the as-yet-undetermined parts of the future. Many philosophers believe that crystal balls are metaphysically possible. In this essay, I argue that they are not. Whether crystal balls are possible matters, for at least two reasons. The first is epistemological. According to a simple, user-friendly chance norm for credence, which I call the Present Principle, agents are rationally required to conform their credences to their expectations of the (...) present chances, deferring to the present chances as they would to an expert. I would like to defend the Present Principle since its truth would do much to simplify the relation between chance and credence. But the Present Principle is counterexample-free, and hence defensible, only if crystal balls are impossible. The second reason is decision-theoretic. The problem of crystal balls is one of the main objections to causal decision theory. But crystal ball cases can be counterexample to causal decision theory only if crystal balls are possible, and, as I argue, crystal balls are not possible. (shrink)

§ . As a corollary to the proposition that all institutions must be subordinated to the law of equal freedom, we cannot choose but admit the right of the citizen to adopt a condition of voluntary outlawry. If every man has freedom to do all that he wills, provided he infringes not the equal freedom of any other man, then he is free to drop connection with the state - to relinquish its protection and to refuse paying toward its support. (...) It is self evident that in so behaving he in no way trenches upon the liberty of others, for his position is a passive one, and while passive he cannot become an aggressor. It is equally self evident that he cannot be compelled to continue one of a political corporation without a breach of the moral law, seeing that citizenship involves payment of taxes; and the taking away of a man's property against his will is an infringement of his rights. Government being simply an agent employed in common by a number of individuals to secure to them certain advantages, the very nature of the connection implies that it is for each to say whether he will employ such an agent or not. If anyone of them determines to ignore this mutual safety confederation, nothing can be said except that he loses all claim to its good offices and exposes himself to the danger of maltreatment - a thing he is quite at liberty to do if he likes. He cannot be coerced into political combination without a breach of the law of equal freedom; he can withdraw from it without committing any such breach, and he has therefore a right so to withdraw.

ABSTRACTThe Necessity of Origins is the thesis that, necessarily, if a material object wholly originates from some particular material, then it could not have wholly originated from any significantly non-overlapping material. Several philosophers have argued for this thesis using as a premise a principle that we call ‘Single Origin Necessity’. However, we argue that Single Origin Necessity is false. So any arguments for The Necessity of Origins that rely on Single Origin Necessity are unsound. We also argue that the Necessity (...) of Origins itself is false. Our arguments rely on a thesis in the ontology of art that we find plausible: Multi-Work Materialism. It is the thesis that works of art that have multiple concrete manifestations are co-located with those manifestations. (shrink)

The study of random graphs was begun in the 1960s and now has a comprehensive literature. This excellent book by one of the top researchers in the field now joins the study of random graphs (and other random discrete objects) with mathematical logic. The methodologies involve probability, discrete structures and logic, with an emphasis on discrete structures.

The Study of Sociology, by English philosopher, biologist, anthropologist, and sociologist, Herbert Spencer, was originally published in 1873. Spencer was known for his contributions to evolutionary theory and for applying it outside of biology, to the fields of philosophy, psychology, and within sociology. In particular, this work is a survey of the foundations of sociology, by one of its founders. Within which he applies the idea of natural selection to the group survival and institutional structures.

The ideas upon which public education was founded in the last half of the nineteenth century were wrong. And despite their continued dominance in educational thinking for a century and a half, these ideas are no more right today. So argues one of the most original and highly regarded educational theorists of our time in 'Getting It Wrong from the Beginning'. Kieran Egan explains how we have come to take mistaken concepts about education for granted and why this dooms our (...) attempts at educational reform. (shrink)
