It is the purpose of this paper to carry out a partial syntactical analysis of imperatives. Imperatives form a large body of linguistic expressions, appearing, e.g. in mathematical proofs be a continuous function!”), laws, moral injunctions, instruction, etc. For analytical purposes we distinguish between two forms of imperatives, the fiat and the directive. By a directive we mean an imperative which includes an indication of the agent who is to carry it out. For example, “Henry, don't forget to stop at (...) the grocery!” is a directive. By a fiat we mean an imperative which includes no reference to an agent who is to carry it out. For example, “Let there be light!” is a fiat. This is a distinction made in terms of meaning. If, however, proper symbolic devices were introduced for the formalization of imperatives, it could be made in a syntactical manner. Thus we could distinguish between imperatives which possess a certain operator—the directive operator formed by putting a name within square brackets—as “[Henry]!”, and imperatives which do not possess this operator, e.g. “Let it be the case that Henry does not forget to stop at the grocery!” In the following we pay attention only to fiats. This, of course, involves a great limitation of subject matter and excludes topics of great interest. (shrink)

The epistemic-basing relation is the relation that holds between a reason, or one’s grounds, and one’s belief when the belief is held for that reason. As I will explain, understanding this relation is crucial for epistemology since basing a belief on a reason seems necessary for epistemic justification to obtain. But what is the nature of this relation? Is it, at least in part, causal as one might assume? Or, due to problems with causal accounts, are rival accounts of the (...) basing relation motivated? That depends whether causal theories are really subject to the standard objections made against them. I will discuss what I take to be the most fundamental objection here. (shrink)

We study logical systems for reasoning about equations involving recursive definitions. In particular, we are interested in "propositional" fragments of the functional language of recursion FLR [18, 17], i.e., without the value passing or abstraction allowed in FLR. The "pure," propositional fragment FLR 0 turns out to coincide with the iteration theories of [1]. Our main focus here concerns the sharp contrast between the simple class of valid identities and the very complex consequence relation over several natural classes of models.

Arising from a graduate course taught to math and engineering students, this text provides a systematic grounding in the theory of Hamiltonian systems, as well as introducing the theory of integrals and reduction. A number of other topics are covered too.

In this paper I consider a recent argument of Timothy Williamson’s that epistemic internalism and content externalism are indeed incompatible, and since he takes content externalism to be above reproach, so much the worse for epistemic internalism. However, I argue that epistemic internalism, properly understood, remains substantially unaffected no matter which view of content turns out to be correct. What is key to the New Evil Genius thought experiment is that, given everything of which the inhabitants are consciously aware, the (...) two worlds are subjectively indistinguishable for them, which is what matters on internalist accounts of epistemic justification. I argue that even if a standard moral of the New Evil Genius intuition is untenable due to considerations arising from content externalism, the case can be understood as supporting epistemic internalism in a way that is wholly compatible with content externalism. In short, epistemic internalism is committed to sameness of justificatory status between subjectively indistinguishable counterparts, not sameness of content of their justifiers. (shrink)

In this paper I identify a tension between the two sets of works by Kuhn regarding the genesis of the “new historiography” of science. In the first, it could be said that the change from the traditional to the new historiography is strictly endogenous. In the second, the change is predominantly exogenous. To address this question, I draw on a text that is considered to be less important among Kuhn’s works, but which, as shall be argued, allows some contact between (...) Kuhn’s two approaches via Koyré. I seek to point out and differentiate the roles of Koyré and Kuhn – from Kuhn’s point of view – in the development of the historiography of science and, as a complement, present some reflections regarding the justification of the new historiography.

The debate about positive and negative claims of conscience is, in large part, about ethical consistency. In this commentary I argue that there can be differences between conscientious provision of treatment and conscientious nonprovision of treatment that are ethically relevant. However, in many cases, including those described in this commentary, there is not sufficient ethical reason to treat them differently. This means that asymmetrical conscientious objection policies are potentially unjustified.

It is a pleasure for me to give this opening address to the Royal Institute of Philosophy Conference on ‘Explanation’ for two reasons. The first is that it is succeeded by exciting symposia and other papers concerned with various special aspects of the topic of explanation. The second is that the conference is being held in my old alma mater, the University of Glasgow, where I did my first degree. Especially due to C. A. Campbell and George Brown there was (...) in the Logic Department a big emphasis on absolute idealism, especially F. H. Bradley. My inclinations were to oppose this line of thought and to espouse the empiricism and realism of Russell, Broad and the like. Empiricism was represented in the department by D. R. Cousin, a modest man who published relatively little, but who was of quite extraordinary philosophical acumen and lucidity, and by Miss M. J. Levett, whose translation of Plato's Theaetetus formed an important part of the philosophy syllabus. (shrink)

No presente artigo, defendemos que uma constelação é formada por gêneros que se diferenciam em seus propósitos comunicativos específicos, mas que podem ser agrupados por razões diversas, como para a realização de uma tarefa para a qual seja necessária uma cadeia de gêneros. (SWALES, 2004). Com base na perspectiva teórica acima, objetivamos discutir as implicações pedagógicas do conceito de constelação de gêneros, tomando como referência o ensino da língua materna. Acreditamos que a compreensão do citado fenômeno, por parte dos professores, (...) pode ser útil para este ensino na medida em que a competência sociodiscursiva dos alunos pode ser ampliada em relação a um determinado elemento motivador da constelação. Isto se justifica porque os gêneros que se constelam se tornam distintos entre si graças à teia de propósitos comunicativos que eles formam dentro da constelação, a fim de atender às mais diversas funções sociais dentro da tarefa maior em função da qual eles se encadeiam. Portanto, o estudo de cadeia de gêneros dentro de uma tarefa escolar maior pode proporcionar aos estudantes uma visão mais ampla da função social dos gêneros, não limitando a compreensão acerca dos modos como a sociedade organiza seus processos comunicativos nos diversos tipos de constelação que podem existir.

This essay defends a view which is near enough to Putnam's characterization of metaphysical realism for it to be called by the same name. Indeterminacy of reference is conceded, in the sense that there may be multiple reference relations, but it is denied that this implied belief in unknowable noumena. It is enough for metaphysical realism as conceived here, that there be at least one reference relation. The essay also argues against defining truth epistemically. Even a Peircean ideal theory might (...) be false, in a contextual sense of might' stronger than that of the logically possible. (shrink)

In this commentary I assess the possible harms to a fetus with trisomy 18 of continued life. I argue that, although there is good reason to avoid subjecting infants to major surgery and prolonged intensive care where there is little chance of benefit, doctors should support and engage honestly with parents who decide to continue their pregnancies. We should ensure that infants with trisomy 18 have access to high quality palliative care.

In 1926, Mally presented the first formal system of deontic logic. His system had several consequences which Mally regarded as surprising but defensible. It also, however, has the consequence that A is obligatory if and only if A is the case, which is unacceptable from the point of view of any reasonable deontic logic. We describe Mally's system and discuss how it might reasonably be repaired.

Individuals are generally held to be morally and legally responsible only for actions carried out freely and deliberately, that is to say, for actions that result from our free choice. However, there is a quite widespread view that all of our actions are the result of the scientific laws that govern our physical bodies. If this should prove to be the case, then human choice would be an illusion, and therefore -- on the generally accepted principle just stated -- personal (...) responsibility would be a meaningless concept and blame and punishment would be inappropriate responses to wicked or criminal acts. In this paper I shall argue that we need to disentangle ‘responsibility’ from ‘choice'. I shall also outline reasons for holding that responsibility is ultimately a first-person matter -- I am responsible if I feel responsible, irrespective of choice -- and I shall briefly consider some of the consequences of this approach.

The traditional view was that a concept must be immediate if anything is, i.e., it must be something possessed directly by my mind. To deny this seems to be saying "I think but I don't have ideas." This is of course what the proponents of the linguistic philosophy are in effect saying, and perhaps for them it is all right. Professor Price has argued ingeniously against the whole linguistic position: against the possibility of a purely linguistic solution to the problem. (...) Yet whether we follow Price or the language philosophers we are forced into a rather puzzling situation. One likes to say that one has ideas, thoughts, concepts, but there is a serious question as to whether we can ever actually cognize such entities. Indeed Price introspects and does not find them. Most of us--including our linguistic colleagues--would be quick to agree. A thought cannot be introspected like an image. There just does not seem to be anything there. As thinkers of thoughts, we are looking inward toward nothing; we are indeed living examples of "hollow men." So it is that we are faced with a dilemma. Either we say we think but do not really have ideas, or we must somehow show that such concepts are actually immediate after all. Neither alternative seems the least bit welcome. The latter seems utterly impossible. (shrink)

Excluding only pure nominalists and "imagists" he includes in the classical theory "almost everyone who lived before the second decade of the twentieth century." This of course covers most of the other general types of theory found in the epistemology textbooks: that concepts are in the mind, that they are also in the thing, and finally that they are fundamentally prior to the thing. These types may be exemplified by Locke, Aristotle, and Plato, respectively. The controversy between these three schools (...) Price feels can for his purposes be regarded as a "domestic difference within the classical tradition." His subsidiary discussions of these differences he confines almost entirely to the first two. The Platonic theory he handles very lightly and gingerly; "it is a sufficiently difficult task in these days to convince people that there is any sense in talking of universals at all, even in the mild and moderate Aristotelian way".

The so-called internalism/externalism debate is of interest in epistemology since it addresses one of the most fundamental questions in the discipline: what is the basic nature of epistemic justification? What has been called epistemic internalism holds, as the label suggests, that all the relevant factors that determine positive epistemic status of a belief must be “internal”. A common way that the “internal” is understood is those things that are, or easily can be, available to the agent’s conscious awareness. However, there (...) is another, and increasingly popular, way of spelling out the epistemically “internal”. A view advocated by Feldman and Conee which they regard as a kind of epistemic internalism, called ‘Mentalism’, holds that epistemic justification strongly supervenes upon the mental. In this paper I will show that even many of those who claim to deny an awareness requirement implicitly appeal to it to motivate their accounts of justification. By considering the arguments for ‘Mentalism’ I will show that, unless an awareness requirement is presupposed, the cases that such arguments appeal to are of no intuitive force. Therefore, insofar as one wants to be an internalist about epistemic justification, one needs to motivate, articulate, and defend an access/awareness condition. Epistemic Internalism, properly construed, ought to stress the epistemic significance of consciousness and the first person perspective. (shrink)

As an immediate reply, meanwhile, I should like to make a remark or two about what is perhaps the central issue raised in the foregoing Comment. This is whether Price's dispositional reduction, or anyone's dispositional reduction can adequately render the act of thinking. Alternatively, the question could, I think, be stated in more presently-favoured language. One could ask whether statements about universals, thoughts, concepts, or ideas can be logically deduced from dispositional statements not containing these "mentalistic" terms. If one is (...) inclined to prefer this more lengthy formulation one may then take this to be my meaning; whenever "dispositional solution" or "dispositional reduction" is mentioned one may translate it into this longer form.

My thesis is on the intersection of epistemology and the philosophy of religion. Contemporary religious epistemology asks the question of how, if at all, can religious belief be rationally justified. I focus on a relatively new tradition that responds to this question known as Reformed Epistemology, as advanced by Alvin Plantinga. Reformed Epistemologists argue that belief in God can be rational, reasonable, and justified without appeal to evidence as was traditionally thought. Plantinga argues that religious belief stems from an innate (...) faculty which produces properly basic beliefs that need not rest on any other beliefs for their justification. My aim is to critically examine these claims. My thesis begins in section I with a discussion of Plantinga’s early attacks on classical foundationalism and Evidentialism, that is, the view that being rational means according one's belief with the evidence. His early goal is to discredit the Evidentialist objection by rebutting the flawed epistemological system he argues it presupposes. In so doing, Plantinga attempts to loosen the canons of basicality to include the belief in God as properly basic. -/- In section II I then discuss Plantinga’s notion of warrant, which is his term for justification – the hallmark difference between true belief and knowledge. After examining the tenability of Plantinga’s concept of what makes belief warranted, I examine how successfully he specifically applies this notion of justification to religious belief. Plantinga’s contention is that religious belief can enjoy enough warrant so that if the belief is true, it will constitute knowledge. In examining this claim I evaluate in section III Plantinga’s evolutionary argument against naturalism, his Aquinas/Calvin model in section IV, potential rationality defeaters in section V and in section VI the larger question of the internalism / externalism debate and its influence on these central issues.
