The extensive community use of complementary medicine can no longer be overlooked in the practice of hospital medicine. Protocols need to be developed and implemented so that health professionals can deal with the issues surrounding the use of CM. Policy development has generally focussed on the supply of CM in hospital but another approach, which is based on consideration of the ethical and legal context, is presented here. Such an approach demands clarification of institutional policy for individuals who are competent (...) and those who are incapable of self-administration or non-competent. (shrink)

Sir Peter Strawson’s ‘Freedom and Resentment’ was a landmark in the philosophical understanding of the free will problem. Building upon it, I attempt to defend a novel position, which purports to provide, in outline, the next step forward. The position presented is based on the descriptively central and normatively crucial role of illusion in the issue of free will. Illusion, I claim, is the vital but neglected key to the free will problem. The proposed position, which may be called (...) ‘Illusionism’, is shown to follow both from the strengths and from the weaknesses of Strawson’s position. (shrink)

A critical note on Peter Lamarque and Nigel Walter’s ‘The Application of Narrative to the Conservation of Historic Buildings’.

Context plays a crucial role in our propositional attitude reporting practices. A belief-reporting sentence which seems true in one context may seem false in another, as Kripke showed us in ‘A Puzzle About Belief.’ To put it a bit sloppily, may seem true when we are discussing Peter's beliefs regarding Paderewski-the-pianist and false when we are discussing his beliefs regarding Paderewski-the-statesman. Peter believes that Paderewski is a fine musician.A number of recent theorists have taken this contextual variation very (...) seriously, and attempted to provide accounts which accommodate it in one way or another. Salmon and Soames accommodate the variation in pragmatics, arguing that our intuitions about attitude reporting often result from mistaking pragmatic implicatures for semantic content. Other theorists have offered semantic accounts which yield contextually varying truth conditions for belief reporting sentences. I have a great deal of sympathy for the project: I think the contextually varying intuitions do exist, and that they need to be accommodated, in one way or another. I am not so sure, however, that this can be done. (shrink)

Saul Kripke's thesis that ordinary proper names are rigid designators is supported by widely shared intuitions about the occurrence of names in ordinary modal contexts. By those intuitions names are scopeless with respect to the modal expressions. That is, sentences in a pair like (a) Aristotle might have been fond of dogs, (b) Concerning Aristotle, it is true that he might have been fond of dogs will have the same truth value. The same does not in general hold for (...) definite descriptions. If one, like Kripke, accounts for this difference by means of the intensions of the names and the descriptions, the conclusion is that names do not in general have the same intension as any normal, identifying description. However, this difference can be accounted for alternatively by appeal to the semantics of the modal expressions. On the account we suggest, dubbed 'relational modality', simple singular terms, like proper names, contribute to modal contexts simply by their actual world reference, not by their descriptive content. That account turns out to be fully equivalent with the rigidity account when it comes to truth of modal and non-modal sentence (with respect to the actual world), and hence supports the same basic intuitions. Here we present the relational modality account and compare it with others, in particular Kripke's own. (shrink)

The adoption question asks whether there are logical rules that cannot be adopted if one does not already infer in accordance with them. Several philosophers, most famously Saul Kripke and Romina Padró, agree that there are such rules. Accordingly, they agree that there is an adoption problem. However, there is disagreement over which rules are unadoptable. In particular, while most agree that if there is an adoption problem, modus ponens and universal instantiation are in its scope, many would exclude (...) adjunction from the list. In this paper, I argue that adjunction is in the scope of the adoption problem. Then I show that the most straightforward counterargument against adjunction being in the scope of the problem, which tries to reformulate the adjunction rule into a more palatable one, does not work.

It seems undeniable that we have many items of modal knowledge. Tradition has it that conceivability is the evidence for possibility that gets us to this modal knowledge. But "conceive" cannot mean think, understand, entertain, suppose, or find believable, because none of these are suited to serve as evidence for possibility, and if it is none of these, it is mysterious what conceivability is, and why it is evidence for possibility. I argue that sensory imagination is the most promising candidate (...) for a source of modal evidence. A theory of imaginative content is developed in Chapter One, one which allows what seems undeniable: that we do imagine the impossible. This raises a challenge to explain why, in the face of our ability to imagine the impossible, we should accept imagination as modal evidence. The predominant response, developed by Saul Kripke, limits the scope of imagination to preserve the link between imagination and what is possible. In Chapter Two I argue that the Kripkean theory is best thought of as an error theory: when we take ourselves to imagine, e.g., water without H2O, or Mark Twain and Sam Clemens in a fistfight, we are mistaken. I articulate and defend an alternative modal epistemology, one that exploits the crucial difference between assigned and basic content of imagining. The evidential value of some imaginings is undermined by independent considerations about the connection between assigned content and ignorance. Instances in which we imagine the impossible are all cases where these independent considerations give us reason to doubt the imagining's value as modal evidence. The conclusions about assigned content are applied in Chapter Three to the first-person imaginings thought to be crucial in philosophy of mind: the imaginability of zombies, and the imaginability of being a disembodied soul. It is argued that such imaginings offer no evidence favoring dualism over materialism. Finally, alternatives to imagination as the source for modal evidence are discussed in Chapter Four. I explore both direct intuition and a priori-based accounts, and conclude that neither offers a genuine alternative to the imagination. (shrink)

Arthur Norman Prior (1914-69) was a logician and philosopher from New Zealand who contributed crucially to the development of ‘non-standard’ logics, especially of the modal variety. His greatest achievement was the invention of modern temporal logic, worked out in close connection with modal logic. However, his work in logic had a much broader scope. He was also the founder of hybrid logic, and he made important contributions to deontic logic, modal logic, the theory of quantification, the nature of propositions and (...) the history of logic. In addition, he discussed questions of ethics, free will, and general theology. Prior’s philosophical works comprise about 200 titles. His earliest articles center on philosophical theology and historical studies of Scottish Reformed Theology. This led on to the publication of his first influential work on ethics: Logic and The Basis of Ethics (1949). With the invention of tense-logic in the early 1950s, his focus shifted to investigations into the syntax of tempo-modal logic leading to his seminal Time and Modality (1957), a volume derived from his John Locke Lectures in Oxford in 1956. Furthermore Prior, together with the Irish mathematician and logician C.A. Meredith (1904-76), made important early contributions to the semantics of possible worlds. Prior’s tense-logic provided a strong conceptual framework for problems pertaining to the philosophy of time. In Time and Modality, Prior discussed the philosophical implications of Ruth Barcan’s famous formulae for tense-logic, and in the 1960s he worked on the notion of the present. The most persistent problem running through Prior’s work is his study of the questions surrounding human freedom and divine foreknowledge, and more general philosophical problems emerging from this classical theological question. His thorough analysis of this problem, with the conceptual tools of tense-logic, received a crucial impetus from his correspondence with the young Saul Kripke, when the latter suggested the semantic tool of branching time to Prior. Prior’s development of two solutions based on branching time for the problem of future contingency, the Peircean and the Ockham solution, was most thoroughly developed in Past, Present and Future (1967), the most important work published by Prior. Characteristically for Prior’s methodological approach, the development of these two solutions were at the same time a development of two new systems of tense logic, and vice versa. One of Prior’s significant contributions to logic was his work on world propositions and instant propositions. In the course of developing these notions he also made one of the earliest formulations of hybrid logic. In Papers on Time and Tense (1968), he presented this idea in a more detailed manner in the context of his four grades of tense-logical involvement. (shrink)

This paper deals with the historical and philosophical background of the introduction of the notion of branching time in philosophical logic as it is revealed in the hitherto unpublished mail-correspondence between Saul Kripke and A.N. Prior in the late 1950s. The paper reveals that the idea was first suggested by Saul Kripke in a letter to A.N. Prior, dated September 3, 1958, and it is shown how the elaboration of the idea in the course of the correspondence was (...) intimately intervowen with considerations of how to represent indeterminism and of the adequacy of tensed logic in light of special relativity. The correspondence underpins the point that Prior's later development of branching time may be understood as a crucial part of his attempt at the formulating a conceptual framework integrating basic human notions of time and free choice.

One way to express the most persistent part of the mind-body problem is to say that there is an “explanatory gap” between the physical and the mental. The gap is not usually taken to apply to all of the mental, but to subjective experience, the mind’s “qualitative” features, or what is now referred to as “phenomenal consciousness.” The “gap” formulation is due to Joseph Levine. He acknowledged the appeal of intuitions of separability between physical facts, of any kind we can (...) envisage, and this aspect of our mental lives. Subjective experience seems not to be the sort of thing that is just the physical under another guise. The immediate focus of Levine’s discussion was a family of arguments due to Saul Kripke. Kripke argued that some influential claims of mind-body identity could not be, as materialists claimed, contingent. If these identities are real then they are necessary. But we can clearly conceive that the mental and physical could come apart—an intuition that “identity theorists” conceded. Given that the identity is necessarily present if present at all, from the fact it is not necessary we can see it is absent. Kripke concluded that physicalism is false. Levine wanted to resist this.

Saul Kripke’s thesis that ordinary proper names are rigid designators is supported by widely shared intuitions about the occurrence of names in ordinary modal contexts. By those intuitions names are scopeless with respect to the modal expressions. That is, sentences in a pair like (a) Aristotle might have been fond of dogs (b) Concerning Aristotle, it is true that he might have been fond of dogs will have the same truth value. The same does not in general hold for (...) definite descriptions. If we, like Kripke, account for this difference by means of the intensions of names and descriptions, we have to conclude that names do not in general have the same intension as any normal, identifying description. However, the difference in scope behavior between names and description can be accounted for alternatively by appeal to the semantics of the modal expressions. On the account we suggest, dubbed ‘relational modality’, simple singular terms, like proper names, contribute to modal contexts simply by their actual world reference, not by their (standard) intension. The relational modality account turns out to be fully equivalent with the rigidity account when it comes to truth of modal and non-modal sentences (with respect to the actual world), and hence supports the same basic intuitions. Given an alternative definition of consequence for relational modality, and a restriction to models with reflexive accessibility relations and non-empty world-bound domains, relational modality also turns out to be model theoretically equivalent with rigidity semantics with respect to logical consequence. Here we introduce the semantics, give the truth definition for relational modality models, and prove the equivalence results. (shrink)

This paper responds to Saul Fisher’s critical note (in the current volume) on Peter Lamarque and Nigel Walter’s ‘The Application of Narrative to the Conservation of Historic Buildings’ (Estetika 1/2019). Walter restates the argument, underlining the context of ‘living' buildings whose identities are still in formation. He then responds to points raised by Fisher, commenting on persistence and identity, Noël Carroll’s views on narrative connection, the usefulness of Carroll's engagement with spatial relations, and addressing some of Fisher’s specific (...) challenges. Lamarque then comments, framing the central question as whether conservation work to a building preserves its character, integrity, and coherence, noting that these are core aspects of narrative, before concluding with some reflections on the application of metaphor, including the metaphorical personification of buildings.

In his famous letter to A. N. Prior dated 3 September 1958, Saul Kripke suggested the use of branching time in temporal logic. In this paper, however, it is argued that Prior worked with an idea close to the notion of branching time (‘the big Y’) already the year before he received Kripke’s letter. It is likely that Prior’s findings based on this early study can explain why Prior so quickly accepted the idea of branching time when he received (...) Kripke’s letter. (shrink)

A transcript of three lectures, given at Princeton University in 1970, which deals with (inter alia) debates concerning proper names in the philosophy of language.

am going to discuss some issues inspired by a well-known paper ofKeith Donnellan, "Reference and Definite Descriptions,”2 but the interest—to me—of the contrast mentioned in my title goes beyond Donnellan's paper: I think it is of considerable constructive as well as critical importance to the philosophy oflanguage. These applications, however, and even everything I might want to say relative to Donnellan’s paper, cannot be discussed in full here because of problems of length. Moreover, although I have a considerable interest in (...) the substantive issues raised by Donnellan’s paper, and by related literature, my own conclusions will be methodological, not substantive. I can put the matter this way: Donnellan’s paper claims to give decisive objections both to Russell’s theory of definite descriptions (taken as a theory about English) and to Strawson’s. My concem is not primarily with the question; is Donnellan right, or is Russell (or Strawson)? Rather, it is with the question: do the considerations in Donneilarfs paper refute Russell’s theory (or Strawson’s)? For definiteness, I will concentrate on Donnellan versus Russell, leaving Strawson aside. And about this issue I will draw a definite conclusion, one which I think will illuminate a few methodological maxims about language. Namely, I will conclude that the considerations in Donnellan’s paper, by themselves, do not refute Russell’s theory. Any conclusions about Russell’s views per se, or Donnellan’s, must be tentative, IfI were to be asked for a tentative stab about Russell, I would say that although his theory does a far better job of handling ordinary discourse than many have thought, and although many popular arguments against it are inconclusive, probably it ultimately fails. The considerations I have in mind have to do with the existence of “improper” definite descriptions, such as “the table," where uniquely specifying conditions are not contained in the description itself..

Frege's theory of indirect contexts and the shift of sense and reference in these contexts has puzzled many. What can the hierarchy of indirect senses, doubly indirect senses, and so on, be? Donald Davidson gave a well-known 'unlearnability' argument against Frege's theory. The present paper argues that the key to Frege's theory lies in the fact that whenever a reference is specified (even though many senses determine a single reference), it is specified in a particular way, so that giving a (...) reference implies giving a sense; and that one must be 'acquainted' with the sense. It is argued that an indirect sense must be 'immediately revelatory' of its reference. General principles for Frege's doctrine of sense and reference are sated, for both direct and indirect quotation, to be understood iteratively. I also discuss Frege's doctrine of tensed and first person statements in the light of my analysis. The views of various other authors are examined. The conclusion is to ascribe to Frege an implicit doctrine of acquaintance similar to that of Russell. (shrink)

Traditionally, many writers, following Kleene (1952), thought of the Church-Turing thesis as unprovable by its nature but having various strong arguments in its favor, including Turing’s analysis of human computation. More recently, the beauty, power, and obvious fundamental importance of this analysis, what Turing (1936) calls “argument I,” has led some writers to give an almost exclusive emphasis on this argument as the unique justification for the Church-Turing thesis. In this chapter I advocate an alternative justification, essentially presupposed by Turing (...) himself in what he calls “argument II.” The idea is that computation is a special form of mathematical deduction. Assuming the steps of the deduction can be stated in a first order language, the Church-Turing thesis follows as a special case of Gödel’s completeness theorem (first order algorithm theorem). I propose this idea as an alternative foundation for the Church-Turing thesis, both for human and machine computation. Clearly the relevant assumptions are justified for computations presently known. Other issues, such as the significance of Gödel’s 1931 Theorem IX for the Entscheidungsproblem, are discussed along the way. (shrink)

This paper is dedicated to the memory of Mike Dunn. His untimely death is a loss not only to logic, computer science, and philosophy, but to all of us who knew and loved him. The paper gives an argument for closure under γ in standard systems of relevance logic (first proved by Meyer and Dunn 1969). For definiteness, I chose the example of R. The proof also applies to E and to the quantified systems RQ and EQ. The argument uses (...) semantic tableaux (with one exceptional rule not satisfying the subformula property). It avoids the previous arguments’ use of cutting down inconsistent sets of formulas to consistent sets. Like all tableau arguments, it extends partial valuations to total valuations. (shrink)

Against recent work by Haslanger and Leslie, I argue that we do not yet have good reason to think that we should single out generics about social groups out as peculiarly destructive, or that we should strive to eradicate them from our usage. Indeed, I suggest they continue to serve a very valuable purpose and we should not rush to condemn them.

Max Stirner was one of the most important and seminal thinkers of the mid-nineteenth century. In the shadows of Hegel, Stirner developed possibly the most radical and devastating critique ever of the discourses of modernity, incurring the ire of Marx, prefiguring Nietzsche, and having a major (though often unacknowledged) impact on diverse streams of thought, from existentialism to anarchism and autonomism, literary and artistic avant-gardes, and postmodern theory. This edited volume investigates Stirner's impact on critical thinking and social and political (...) thought, exploring his radical and contemporary importance as a political theorist. In unmasking the religiosity lurking behind discourses of humanism and rationalism, and the domination of the individual immanent within liberal modes of politics, Stirner demolished the ontological foundations and universal grand narratives of our modernity. His thought has implications for contemporary questions of ideology, power, subjectivity, ethics and action, and opens the way for entirely new forms of politics. (shrink)

Denialism concerning free will and moral responsibility combines, in its minimal form, the rejection of libertarian free will and the rejection of compatibilism. I will address the more ambitiously “happy” or “optimistic” version of denialism, which also claims that we are better off without belief in free will and moral responsibility, and ought to try to radically reform our moral, social and personal lives without such beliefs. I argue that such denialism involves, for various reasons, a dangerous gamble, which it (...) would be morally irresponsible to follow. I conclude by reflecting upon the implications. (shrink)

At the University of Sheffield during 2011 and 2012, a leading group of philosophers, psychologists, and others gathered to explore the nature and significance of implicit bias. The two volumes of Implicit Bias and Philosophy emerge from these workshops. Each volume philosophically examines core areas of psychological research on implicit bias as well as the ramifications of implicit bias for core areas of philosophy. Volume I: Metaphysics and Epistemology is comprised of two parts: “The Nature of Implicit Attitudes, Implicit Bias, (...) and Stereotype Threat,” and “Skepticism, Social Knowledge, and Rationality.” The first part contains chapters examining the relationship between implicit attitudes and “dual process” models of the mind; the role of affect in the formation and change of implicit associations; the unity (or disunity) of implicit attitudes; whether implicit biases are mental states at all; and whether performances on stereotype-relevant tasks are automatic and unconscious or intentional and strategic. The second part contains chapters examining implicit bias and skepticism; the effects of implicit bias on scientific research; the accessibility of social stereotypes in epistemic environments; the effects of implicit bias on the self-perception of members of stigmatized social groups as rational agents; the role of gender stereotypes in philosophy; and the role of heuristics in biased reasoning.

One of the most important aspects of Grice’s theory of conversation is the drawing of a borderline between what is said and what is implic- ated. Grice’s views concerning this borderline have been strongly and influentially criticised by relevance theorists. In particular, it has become increasingly widely accepted that Grice’s notion of what is said is too lim- ited, and that pragmatics has a far larger role to play in determining what is said than Grice would have allowed. (See for (...) example Bezuidenhuit 1996; Blakemore 1987; Carston 1991; Recanati 1991, 1993, 2001; Sperber and Wilson 1986; Wilson and Sperber 1981.) In this paper, I argue that the rejection of Grice has moved too swiftly, as a key line of objection which has led to this rejection is flawed. The flaw, we will see, is that relevance theorists rely on a misunderstanding of Grice’s project in his theory of conversation. I am not arguing that Grice’s versions of saying and implicating are right in all details, but simply that certain widespread reasons for rejecting his theory are based on misconceptions. (shrink)

As I write this, in November 1971, people are dying in East Bengal from lack of food, shelter, and medical caxc. The suffering and death that are occurring there now axe not inevitable, 1101; unavoidable in any fatalistic sense of the term. Constant poverty, a cyclone, and a civil war have turned at least nine million people into destitute refugees; nevertheless, it is not beyond Lhe capacity of the richer nations to give enough assistance to reduce any further suffering to (...) very small proportions. The decisions arid actions of human beings can prevent this kind of suffering. Unfortunately, human beings have not made the necessary decisions. At the individual level, people have, with very few exceptions, not responded to the situation in any signihczmt way. Generally speaking, people have not given large sums to relief funds; they have not written t0 their parliamentaxy representatives demanding increased government assistance; they have not demonstrated in the streets, held symbolic fasts, or done anything else directed toward providing thc refugees with the means to satisfy their essential needs.

My aim in this chapter is to show how Stirner’s critical post-humanist philosophy allows him to engage with a specific problem in political theory, that of voluntary servitude – in other words, the wilful acquiescence of people to the power that dominates them. Here it will be argued that Stirner’s demolition of the abstract idealism of humanism, rational truth and morality, and his alternative project of grounding reality in the singularity of the individual ego, may be understood as a way (...) of countering and avoiding this condition of self-domination. In contrast to various claims, then, that Stirner’s thought is nihilistic, one finds in Stirner a series of ethical strategies through which the self’s relation to power is interrogated and in which the possibility of alternative modes of subjectivity is opened up; where the subject can invent for himself new forms of existence and practices of freedom that release him from this condition of subjection. There emerges from Stirner’s thought a certain kind of micro-politics and ethics which has important implications for any consideration of radical politics today. (shrink)

In this book Saul Kripke brings his powerful philosophical intelligence to bear on Wittgenstein's analysis of the notion of following a rule.

With the COVID-19 crisis forcing us to reflect in a dramatic way on the limits of the human and the implications of the Anthropocene Age, this timely volume addresses these concerns through an exploration of post-humanism as represented in philosophy, politics and aesthetics. Global pandemics bring into sharp focus the bankruptcy of the neoliberal economic paradigm, the future of the arts sector in society, and our dependence upon political forces outside our control. In response to the recent state of emergency, (...) Pandemic and the New Posthuman highlights the urgent need to rethink our anthropocentrism and develop new political models, aesthetic practices and ways of living. Central to these discussions is the idea of post-humanism, a philosophy that can help us grapple with the crisis, as it takes seriously the unstable ecosystems on which we depend and the precarious nature of our long-cherished notions of agency and sovereignty. Bringing together international philosophers, political theorists and media and art theorists, all of whom engage with the posthuman, this volume explores a range of vital subjects, from the inequality revealed by COVID-19 survival rates to museums' role in spreading human-centric understandings of a world struck by human fragility. Facing up to the realities that the coronavirus outbreak has uncovered, Pandemic and the New Posthuman combines both breadth and depth of analysis to take on the posthuman challenges confronting us today.

A formal theory of truth, alternative to tarski's 'orthodox' theory, based on truth-value gaps, is presented. the theory is proposed as a fairly plausible model for natural language and as one which allows rigorous definitions to be given for various intuitive concepts, such as those of 'grounded' and 'paradoxical' sentences.

Reference and Existence, Saul Kripke's John Locke Lectures for 1973, can be read as a sequel to his classic Naming and Necessity. It confronts important issues left open in that work -- among them, the semantics of proper names and natural kind terms as they occur in fiction and in myth; negative existential statements; the ontology of fiction and myth. In treating these questions, he makes a number of methodological observations that go beyond the framework of his earlier book (...) -- including the striking claim that fiction cannot provide a test for theories of reference and naming. In addition, these lectures provide a glimpse into the transition to the pragmatics of singular reference that dominated his influential paper, " Speaker's Reference and Semantic Reference " -- a paper that helped reorient linguistic and philosophical semantics. Some of the themes have been worked out in later writings by other philosophers -- many influenced by typescripts of the lectures in circulation -- but none have approached the careful, systematic treatment provided here. The virtuosity of Naming and Necessity -- the colloquial ease of the tone, the dazzling, on-the-spot formulations, the logical structure of the overall view gradually emerging over the course of the lectures -- is on display here as well.

We propose a solution to the problem of logical omniscience in what we take to be its fundamental version: as concerning arbitrary agents and the knowledge attitude per se. Our logic of knowledge is a spin-off from a general theory of thick content, whereby the content of a sentence has two components: an intension, taking care of truth conditions; and a topic, taking care of subject matter. We present a list of plausible logical validities and invalidities for the logic of (...) knowledge per se for arbitrary agents, and isolate three explanatory factors for them: the topic-sensitivity of content; the fragmentation of knowledge states; the defeasibility of knowledge acquisition. We then present a novel dynamic epistemic logic that yields precisely the desired validities and invalidities, for which we provide expressivity and completeness results. We contrast this with related systems and address possible objections. (shrink)

As the premier early modern advocate of an Epicurean alternative to the prevailing neo-Scholastic framework of Aristotelianism, Pierre Gassendi promoted not only ancient but also innovative reasoning on behalf of atomism, probabilism, empiricism, psychological hedonism, social contractarianism, and a range of other stances associated with the philosophy of the Garden. Much commentary has focused on the extent to which Gassendi ‘baptizes’ Epicurean thought. Beyond this aspect of his Epicureanism are questions as to whether, and how, Gassendi is true to core (...) Epicurean thinking, and what he preserves and promotes as valuable to philosophical and natural investigations of his time. Indeed, much subsequent modern philosophy builds on or reacts to an Epicurean legacy bequeathed by Gassendi, comprising his adjustments to, constraints on, or corrections of, the canonical views. Yet, for all his amendments, he retains as a primary philosophical motivation the Epicurean goal of striving for ataraxia. In this, he signals his firm commitment to philosophy in the tradition of the canonical Epicurean views. And, as with Epicurus’ own notion, his account of the centrality of attaining tranquility directs us to a better understanding of our nature and that of the world around us; amenable, in Gassendi’s framework, to Christian thought and contemporary natural philosophical investigations.
