In the last 30 years much philosophical discussion has been generated by Kripke’s proof of the necessity of origin for material objects presented in footnote 56 of ‘Naming and Necessity’. I consider the two most popular reconstructions of Kripke’s argument: one appealing to the necessary sufficiency of origin, and the other employing a strong independence principle allegedly derived from the necessary local nature of prevention. I argue that, to achieve a general result, both reconstructions presuppose an (...) implicit Humean atomistic thesis of recombination, according to which any two (non-overlapping) possible objects can simultaneously coexist in one and the same world. Yet recombination ill accords with the other assumptions of the proofs. I also argue that the locality of prevention does not entail strong independence. (shrink)

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 necessity of origin suggests that a person’s identity is determined by the particular pair of gametes from which the person originated. An implication is that speculative scenarios concerning how we might otherwise have been had our gametic origins been different are dismissed as being metaphysically impossible. Given, however, that many of these speculations are intelligible and commonplace in the discourses of competent speakers, it is overhasty to dismiss them as mistakes. This paper offers a way of understanding (...) these speculations that does not commit them to incoherence but aims to make the best sense of what they are expressing. Using the philosophical framework of two‐dimensional semantics, it proposes that the speculative scenarios are best analysed as epistemic possibilities, rather than as metaphysical possibilities. It then explores some implications of this analysis for the ethical challenges associated with the non‐identity problem. (shrink)

In ‘A New Route to the Necessity of Origin’, Rohbraugh and deRosset offer an argument for the Necessity of Origin appealing neither to Suffciency of Origin nor to a branching-times model of necessity. What is doing the crucial work in their argument is instead the thesis they name ‘Locality of Prevention’. In this response, we object that their argument is question-begging by showing, first, that the locality of prevention thesis is not strong enough to (...) satisfactorily derive from it the intended conclusion, and, second, that the argument is not sound unless the Necessity of Origin is operating as an implicit premiss.

The once deeply held conviction that all necessary truths are known a priori is now widely, although by no means universally agreed to have been subjected to penetrating, if not devastating criticism. Scott Soames, for example, on behalf of Saul Kripke, and indirectly of Hilary Putnam, argues that in respect of natural kinds, the introduction of basic essentialist assumptions grounded in our pre-theoretical habits of thinking and speaking – for example, that atomic or molecular structure provides the underlying essence of (...) a substance – allows a sentence like "water = H 2 0," in which the identity sign is flanked by rigid designators to express a metaphysically necessary truth. Yet doubts and puzzlement remain over the status of a posteriori necessities, including those relating to an individual's origin. This paper considers some prominent criticisms that have been made of the Kripke–Putnam approach by A. J. Ayer and Frank Ebersole among others and reveals in what respects they are valid, where they are misplaced, and, perhaps more importantly, why the most valuable aspect of this approach can be seen to reflect aspects of our scientific procedures that do indeed point towards an application for a distinction that roughly mirrors that between epistemic and metaphysical possibility, yet one that is grounded instead in the nature of our actual practices. (shrink)

In ‘Naming and Necessity,’ Saul Kripke defends a number of essentialist claims. One of them is that having a certain origin is a necessary property of a material thing. Used in connection with a human being or, presumably, a living thing of another kind whose members sexually reproduce, ‘necessity of origin’ means that the organism must have been born of those individuals who are its parents, i.e., whose body tissues are sources of the sperm and egg (...) from which it issued, in the actual world. To say that the origin of an inanimate material thing is necessary is to say that having its origin in the hunk of matter from which it came is essential to it. (shrink)

Saul Kripke has claimed that there are necessary connections between material things and their material origins. The usual defences of such necessity of origin theses appeal to either a sufficiency of origin principle or a branching-times model of necessity. In this paper we offer a different defence. Our argument proceeds from more modest ‘independence principles’, which govern the processes by which material objects are produced. Independence principles are motivated, in turn, by appeal to a plausible metaphysical (...) principle governing such processes, their invulnerability to non-local prevention. We outline the new argument, and distinguish it from both of the usual defences. (shrink)

In this article I contrast two opposing forms of essentialism, definitional and transcendental versus productivist and historical, and trace both forms back to Kripke's Naming and Necessity (1980). Definitional essentialism, as developed by Fine, centers on kind-membership. Historical essentialism, as anticipated by Prior and developed by Almog, puts origin at its center. The article focuses on the fundamentally distinct manners in which these two views handle the necessity of origin thesis. In the final section of the (...) article, inspired by a Nietzschean genealogical methodology, I pursue a naturalization strategy and conclude that rather than origin being necessary, it is essentialist necessity that reduces to origin.

A thought that we all entertain at some time or other is that the course of our lives might have been very different from the way they in fact have been, with the consequence that we might have been rather different sorts of persons than we actually are. A less common, but prima facie intelligible thought is that we might never have existed at all, though someone rather like us did. Arguably, any plausible theory of personal identity should be able (...) to accommodate both possibilities. Certain currently popular Reductionist theories of personal identity, however, seem to be deficient in precisely this respect. This paper explores some Reductionist responses to that challenge.

Emile Benvcniste may be used to introduce the topic. The French linguist begins an essay on “Euphemisms Ancient and Modern” with a paradox about the early Greek definitions of euphemism. “To speak words which augur well” is one meaning given, but another is “to maintain silence”. This initial contradiction is further compounded by yet a third expression, “to shout in triumph”. The dilemma is. however, easily dissolved. To speak words which augur well implies, for special occasions, an exhortation even to (...) shout triumphantly, “to assent by an, auspicious outcry”: it further implies, again depending on the circumstances, “to avoid words which augur ill”, hence, if necessary, to say nothing. As one definition explains “avoid all unlucky words during sacred rites: hence, as the surest mode of avoiding them, keep a religious silence” (original emphasis). Paradox terminates; we are merely dealing with “a euphemism for a euphemism” taking an expression of Benveniste out of context. (shrink)

What is unique and essential about theatre? What separates it from other arts? Do we need 'theatre' in some fundamental way? The art of theatre, as Paul Woodruff says in this elegant and unique book, is as necessary-and as powerful-as language itself. Defining theatre broadly, including sporting events and social rituals, he treats traditional theatre as only one possibility in an art that-at its most powerful-can change lives and bring a divine presence to earth. The Necessity of Theater analyzes (...) the unique power of theatre by separating it into the twin arts of watching and being watched, practiced together in harmony by watchers and the watched. Whereas performers practice the art of being watched-making their actions worth watching, and paying attention to action, choice, plot, character, mimesis, and the sacredness of performance space-audiences practice the art of watching: paying close attention. A good audience is emotionally engaged as spectators; their engagement takes a form of empathy that can lead to a special kind of human wisdom. As Plato implied, theatre cannot teach us transcendent truths, but it can teach us about ourselves. Characteristically thoughtful, probing, and original, Paul Woodruff makes the case for theatre as a unique form of expression connected to our most human insticts. The Necessity of Theater should appeal to anyone seriously interested or involved in theatre or performance more broadly. (shrink)

Are properties perfectly natural (or not) relative to worlds, or are they perfectly natural (or not) tout court? That is, could there be a property P that is instanti-ated at worlds w1 and w2, and is perfectly natural at w1 but not at w2?

Along the way, we reply to a prima facie compelling argument for the contin-gency of perfect naturalness, based upon the connection between natural prop-erties and (...) laws of nature. (shrink)

The purpose of this article is to elaborate on the concept of prefiguration by outlining the necessity of its contribution to a progressive public philosophy for the 2020s. In the introduction, I explain how the object of critique for many social theorists has shifted over the course of the last decade from neoliberal globalization to capitalism understood as an encompassing form of life. In light of this, I enumerate the features that should define a progressive public philosophy: radical, emancipatory, (...) and decolonized. The introduction is followed by an overview of the academic debates emerging after the North Atlantic financial crisis of 2007–8. Among these, accelerationism fundamentally rejects the incorporation of prefigurative politics in any emancipatory political agenda. To better understand this position, I examine the origin and meaning of prefiguration and prefigurative practices in more detail in Section III. In it, I argue that prefigurative politics entails a holistic approach to social change that digs its roots in feminist and ecological thought and focuses on social reproduction and the preservation of life rather than solely economic production. Subsequently, I deploy the case of Occupy Wall Street to show that a growing number of contemporary social movements are implementing a dualistic strategy that simultaneously combines repertoires of action typical of protest movements with prefigurative practices focused on the embodiment of alternatives. This dualism, along with the limited success of Occupy Wall Street in concretizing its claims and goals, has led prefigurative politics to being labelled as incompatible with, if not even hindering, any emancipatory strategy. My argument instead is that prefigurative politics constitutes a fundamental and necessary component of any political strategy aimed at transcending contemporary capitalism since it conceives progressive social change in an ontologically and epistemologically different way with respect to political parties and protest movements. Taking this into consideration, I conclude that conventional politics and prefigurative politics can be seen as having the potential to mutually reinforce each other and that prefigurative politics should be acknowledged as a pivotal concept in establishing a progressive public philosophy for the 2020s. Only by doing so, will this philosophy be truly radical, emancipatory, and decolonial. (shrink)

Joseph Keim Campbell has recently criticized Peter van Inwagen's Third Argument against compatibilism for its reliance on the existence of a remote past. In response, Anthony Brueckner has offered a new version of the Third Argument showing that determinism and free will are incompatible for all times t relative to which there is a past . In this paper I argue that although Brueckner's retooled argument fails to prove anything in favour of incompatibilism, its conclusion can be exploited to provide (...) another version of van Inwagen's original argument that doesn't rely on the existence of past times, thus withstanding Campbell's criticism.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Pragmatism, Democracy, and the Necessity of RhetoricScott R. StroudPragmatism, Democracy, and the Necessity of Rhetoric by Robert Danisch Columbia: University of South Carolina Press, 2007. Pp. xii + 190. $39.95, cloth.The classical pragmatists are an infuriating bunch for those in rhetorical studies. For instance, the commitment of William James and John Dewey to uncertainty and change in politics and epistemology stands to position them with those (...) studying rhetoric as a necessary tool in the uncertain situation that humans find themselves in—be it in nature or in society. But the pragmatists steadfastly avoid engaging (or even using) the concepts of rhetorical theory or practice. Even the commentary of James and Dewey on "communication" is vague and often perfunctory. Thus, contemporary rhetorical scholars find themselves at an impasse—Do they talk about the pragmatists, even though the pragmatists do not engage the rhetorical tradition in a sustained fashion, or do they simply ignore this important and fairly original strain of American thought (perhaps in favor of European lines of philosophical thought)? I believe that the more interesting choice is to pursue the former option and to engage the pragmatists in terms of what they have to offer communication studies and the study of rhetoric. This, of course, will necessitate acknowledging their compatibility and relative lack of engagement with the rhetorical tradition. The rewards of such a constructive engagement, however, could be great for the study of communication and rhetoric.This is the path that Robert Danisch's recent book, Pragmatism, Democracy, and the Necessity of Rhetoric, sets out to traverse. The stated project [End Page 96] of this work is to show the compatibility of the classical rhetorical tradition and the pragmatist tradition. Beyond this, Danisch attempts to show that rhetoric is essential to the pragmatist project and that a variety of rhetorics can be identified in the actual work or practices of important American pragmatists. As he clearly puts it in his concluding chapter, "This is precisely the purpose of pragmatism—it was designed as a philosophy that would ultimately extend beyond itself to invent tools, techniques, ideas, and instruments of change that it alone could not imagine. It is my contention that rhetorics and rhetorical theories are just those tools, techniques, ideas, and instruments" (144). I believe that Danisch goes an admirable distance in making this case and in furthering the still-nascent work that strives to connect rhetoric and pragmatism.Danisch begins his case for connecting rhetoric and pragmatism by addressing the two traditions in general terms. First, he limits his inquiry to classical rhetoric, although his concluding chapter features issues and figures within more recent rhetorical scholarship. This is a defensible strategy, as "rhetoric" is almost as ambiguous and inexact as "pragmatism." What connects both classical rhetoric and pragmatism, according to Danisch's way of setting up the analysis, is that both traditions represent approaches or orientations toward the world and society. Both see the world as fundamentally uncertain, and both see human action as playing a vital role in creating what actually "is" the case, whether it is in terms of scientific knowledge or political institutions. He clarifies this in terms of how rhetoric and pragmatism focus on action—"The question for both pragmatism and rhetoric concerns method. Active human agents employ tools and techniques designed to order and influence human affairs; pragmatism and rhetoric share this concern" (39). Thus, both focus on methods of guiding and directing human action such that it results in the sort of world that we want to instantiate or create. Danisch attempts to explore the connection of these two traditions, and he promises that beyond being possible, it will be rewarding in three ways. First, pragmatism seems to offer the resources and opportunities to develop "rhetorics based on its principles and fit to the problems of contemporary democracy" (15). Second, such an engagement of pragmatism with the concepts of classical rhetoric will reaffirm the importance of these classical concepts in today's circumstances. Third, both pragmatism and rhetoric will be improved, since "philosophies are improved by exploring their relationships to rhetoric, and rhetorics are improved by exploring their intellectual justifications" (15). Some may be uneasy... (shrink)

This collection of papers builds on the idea that the bioeconomy provides a framework for potentially effective solutions addressing the grand global challenges by a turn towards an increased use of biological resources, towards renewability and circularity. Consequently, it cannot be perceived as an end in itself. Thus, innovative endeavors within this bioeconomy framework require a serious examination of their normative premises and implications. From different perspectives, the five contributions to the collection demonstrate that for a bioeconomy that is to (...) contribute to the transformation towards sustainability, inquiries into norms, values, and paradigms of innovators and other stakeholders are indispensable. Originating in the spirit of an interdisciplinary workshop on the "The Normative Dimension of Transformations towards a Sustainable Bioeconomy", the collection at hand provides an attempt to facilitate an increased commitment of social sciences into bioeconomy discourses. We learn: the bioeconomy is on the rise as it is, but whether it will guide us the way towards an equitable, environmentally sound, and future-proof economy, heavily depends on the normative guardrails imposed by science, society, and business. Recent discussions have shown that the pressing problems and complex challenges humanity is currently facing cannot be adequately tackled by approaches that. (shrink)

Technological advancement has an ambivalent character concerning the impact on biodiversity. It accounts for major detrimental environmental impacts and aggravates threads to biodiversity. On the other hand, from an application perspective of environmental science, there are technical advancements, which increase the potential of analysis, detection and monitoring of environmental changes and open a wider spectrum of sustainable use strategies.The concept of biodiversity emerged in the last two decades as a political issue to protect the structural and functional basis of earthbound (...) life. In this respect, it represents a great challenge for science, in particular for ecology, which is the scientific discipline mainly involved in contributing to understand biodiversity issues.In this paper, we state a strong necessity for ecologists to work in close connection with other disciplines and within their own discipline across the different organisation levels. Each level has some specific properties to which ecological terminology has been adapted, and joint views are necessary to understand complex networks. In this context, ecological theory provides the background to analyse biological complexity and the relationship of structure and dynamics on different integration levels and provides the interface to mediate social and political issues.Important features of new technologies for advances in ecological theory refer to an increase in information processing capacities, more efficient automatic data acquisition and device operation, and an increase in resolution.One crucial consideration we analyse is the trend that a quantitative development in one particular discipline may open a new potential for qualitative advancement in other disciplines when the quantitative advancement is applied in a new disciplinary context.We illustrate these qualitative developments that are based on technological advancements and which helped to advance ecological theory qualitatively with two examples: The underlying mechanisms causing regularly oscillating rodent populations are subject to a decade long discussion in ecology. Using the possibilities of modern information processing, it is possible to represent the discussed hypotheses in an integrative object oriented model and analyse how the underlying causal net works. The second example originates from biosafety research dealing with the environmental impact of genetically modified organisms. The project GenEERA develops a complex up-scaling procedure from below field-level information to the landscape scale in order to investigate spread and persistence of GM oil seed rape under different scenarios. The approach gives an example, how ecological modelling can be used to combine different information levels to derive conclusions on a higher spatial scale.In an overall conclusion we relate the described approaches to a wider system analytical context in which we interpret theory developments and biodiversity issues with a system theoretical description of growth processes. We obtain the view that in self-organising systems there is a tendency for autonomous development which tends to be dominating far away from capacity limitations. However, while approaching capacity limitations, a tendency towards closer coupling of internal and external cause-effect networks emerges. We also find that the relation of biodiversity, ecosystem services, and social dynamics can be interpreted in this framework. In this context, the demand for closer interdisciplinary cooperation to solve existing problems appears as an indication of emerging capacity limitations both, in the theoretical as well as in the physical domain.

Must we believe in logical necessity? I examine an argument for an affirmative answer given by Ian McFetridge in his posthumously published paper 'Logical Necessity: Some Issues', and explain why it fails, as it stands, to establish his conclusion. I contend, however, that McFetridge's argument can be effectively buttressed by drawing upon another argument aimed at establishing that we ought to believe that some propositions are logically necessary, given by Crispin Wright in his paper 'Inventing Logical necessity'. (...) My contention is that Wright's argument, whilst it likewise fails, as it stands, to establish the necessity of necessity, established enough to close off what appears to me to be the only effective-looking sceptical response to McFetridge's original argument. My paper falls into four principal parts. In the first I expound McFetridge's argument and draw attention to the possibility of a certain type of sceptical counter to it. In the second, I begin a response to this sceptical move, taking it as far as I can without reliance upon argument of the kind given by Wright. Turning, then, to Wright's argument, I explain to what extent I think it is successful and seek to rebut some objections to the argument which, were they well-taken, would show that the argument cannot enjoy even the partial success I which to claim for it. Finally, I return to my main theme and try to show, with the assistance of what I take to be solidly established by Wright's argument, that the sceptical response collapses. (shrink)

The view (most prominently advocated by Justice Scalia) that original meaning entails the constitutionality of original practices has strong intuitive appeal and has been broadly assumed by originalists and nonoriginalists alike. But the position is mistaken. We suggest that a failure to distinguish between two different notions of meaning accounts for the position's wide currency. According to the first notion, the meaning of a term is roughly what a dictionary definition attempts to convey--the semantic or linguistic understanding necessary to use (...) the term, as opposed to nonlinguistic facts about the objects or activities to which the term applies. In contrast, according to the second, looser notion, the meaning of a term incorporates the objects or activities to which the term is applied. The first notion lies behind originalism's theoretical force; it is untenable that the meaning of the Constitution in the first sense could evolve. In sharp contrast, it is not only tenable but inevitable that changes occur over time in the class of things to which a constitutional provision is applied. Once recognized, the distinction undermines the seemingly natural move from the necessity of interpreting the Constitution in accordance with how it was originally understood to the necessity of upholding practices originally understood to be constitutional. By taking the distinction on board and rejecting the assumption, originalism can readily deflect the challenges based on unacceptable original practices; as a consequence, however, it will not be tenable for originalism, in any case challenging an original practice, simply to rule out the possibility of the practice's invalidity.

In lieu of an abstract, here is a brief excerpt of the content:Papirius and the Chickens, or Machiavelli on the Necessity of Interpreting ReligionJohn M. Najemy*No aspect of Machiavelli’s thought elicits a wider range of interpretations than religion, and one may wonder why his utterances on this subject appear to move in so many different directions and cause his readers to see such different things. One reason is of course his famous challenge to conventional piety in the advice to (...) princes (in chapter 18 of The Prince) that, while it is important to appear to be “all compassion, faith, integrity, humanity, and religione, and there is nothing more necessary for a prince than to appear to have the last of these,” these “qualities” can actually be “damaging” if a prince insists on observing them at all times. For it is sometimes necessary to act “against faith, against charity, against humanity, and against religione.” 1 Machiavelli probably never wrote more famous or infamous words than these, even though they express an obvious, and hardly original, truth about all politics. But the world of the later sixteenth- and seventeenth-century reformations and religious absolutisms could not tolerate such honesty, and Machiavelli’s reputation was quickly tarred with accusations of devilish immorality by the very societies that thought it was godly to burn heretics. On the issue of religion Machiavelli became, and to some extent remains, a convenient scapegoat often blamed for the decline of religion in the modern world, all of which has no doubt intensified the polemical and ideological nature of the debates surrounding his views of religion in general and Christianity in particular. [End Page 659]The polar positions in the interpretation of Machiavelli’s ideas about religion are represented by Leo Strauss and Sebastian de Grazia. For Strauss, Machiavelli was a “teacher of evil,” a “blasphemer,” and a purveyor of lessons of a “diabolical” and “soulless character” whose purpose was to sabotage the heritage of thought and morality inherited from both Christianity and Greek philosophy. 2 De Grazia, by contrast, has recently given us a Machiavelli who “discourses about God always in the conventional reverent attitude,” who “never questions that there is good and evil,” and who, “by associating virtuous political action with grace and glory... argues that through this kind of active and political virtue men conform to God’s desire.” “Behind Niccolò’s insistence on political action,” says de Grazia, “stands God. He grants His grace when it is earned—in political coin.” 3 Part of the fascination of Machiavelli scholarship is the mystery of how this most outspoken and direct of political thinkers—a writer who pulled no punches and minced no words—could be the common referent of such wildly different readings. But it is equally curious to observe how uncannily these extreme positions mirror each other. Both give us true believers, one in the Word, the other in the subversion of the Word; and in both cases a believer who is always of a piece, true to himself, and possessed of an unshakeable commitment—whether positive or negative—toward the transcendent truth of Christianity. In short, for all the obvious differences, the similarities between Strauss’s “diabolical” Machiavelli and de Grazia’s reverent “friend of God” remind one of the old myth that devils are after all only fallen angels.The papers in this forum should certainly remove any doubt about the importance of religion in Machiavelli’s thought. They remind us of the prominence of religious language and examples in Machiavelli’s texts: his call for the “redemption” of Italy in the last chapter of The Prince; the esteem in which he holds the heads and founders of religions, whom he declares, in Discourses 1.10, to be the most praised of all famous men; the crucial appeal to the figure of Moses as the prototype of both founders of states and liberators of enslaved peoples; the central role that Machiavelli attributes to religion among the factors responsible for Rome’s power, unity, and political success; and his provocative critique of Christianity, which leads him, in a number of places, to blame the Christian faith for the relative weakness of both modern states and the modern ethic of citizenship. 4 The authors...

In footnote 56 of his Naming and Necessity, Kripke offers a ‘proof’ of the essentiality of origin. On its most literal reading the argument is clearly flawed, as was made clear by Nathan Salmon. Salmon attempts to save the literal reading of the argument, but I argue that the new argument is flawed as well, and that it can’t be what Kripke intended. I offer an alternative reconstruction of Kripke’s argument, but I show that this suffers from a (...) more subtle fault. (shrink)

With a large number of forcibly displaced people seeking safety, the EU is facing a challenge in maintaining solidarity. Europe has seen millions of asylum seekers crossing European borders, the largest number of asylum seekers since the second world war. Endemic diseases and often failing health systems in their countries of origin, and arduous conditions during transit, raise questions around how to meet the health needs of this vulnerable population on arrival in terms of screening, vaccination, and access to (...) timely and appropriate statutory health services. This paper explores the potential role of the principle of reciprocity, defined as the disposition ‘to return good in proportion to the good we receive, and to make reparations for the harm we have done’, as a mid-level principle in infectious disease screening policies. More than half of the European countries implemented screening programmes for newly arrived asylum seekers. Screening may serve to avoid potential infectious disease risks in the receiving countries as well as help identify health needs of asylum seekers. But screening may infringe upon basic rights of those screened, thus creating an ethical dilemma. The use of the principle of reciprocity can contribute to the identification of potential improvements for current screening programmes and emphasizes the importance of certain rights into guidelines for screening. It may create a two way moral obligation, upon asylum seekers to actively participate in the programme, and upon authorities to reciprocate the asylum seekers’ participation and the benefits for the control of public health. The authors argue that the reciprocity principle leads to a stronger ethical justification of screening programmes and help achieve a balance between justifiable rights claims of the host population and the asylum seekers. The principle deserves a further and more thorough exploration of its potential use in the field of screening, migration and infectious diseases. (shrink)

This brief paper argues that Kripke’s thesis of the necessity of origin has some implausible consequences.

Due to the influence of Nathan Salmon’s views, endorsement of the “flexibility of origins” thesis is often thought to carry a commitment to the denial of S4. This paper rejects the existence of this commitment and examines how Peacocke’s theory of the modal may accommodate flexibility of origins without denying S4. One of the essential features of Peacocke’s account is the identification of the Principles of Possibility, which include the Modal Extension Principle (MEP), and a set of Constitutive Principles. Regarding (...) their modal status, Peacocke argues for the necessity of MEP, but leaves open the possibility that some of the Constitutive Principles be only contingently true. Here, I show that the contingency of the Constitutive Principles is inconsistent with the recursivity of MEP, and this makes the account validate S4. It is also shown that, compatibly with the necessity of the Constitutive Principles, the account can still accommodate intuitions about flexibility of origins. However, the account we end up with once those intuitions are consistently accommodated may not be satisfactory, and this opens up the debate about whether or not artefacts allow for some variation in their origins.

We show that if the weak compactness of a cardinal is made indestructible by means of any preparatory forcing of a certain general type, including any forcing naively resembling the Laver preparation, then the cardinal was originally supercompact. We then apply this theorem to show that the hypothesis of supercompactness is necessary for certain proof schemata.

Much has happened in modal logic since 1947. In particular, in regard to the problem of interpreting such logics. In that fateful year Quine published his seminal paper “The Problem of Interpreting Modal Logic” from which this work takes inspiration. Since then a certain kind of model theory – universally referred to as “possible worlds semantics” – has come to dominate both advanced research and introductory textbooks. Many would say that the problem of interpreting modal logic has been resolved. In (...) the work below I argue that some of the 1947 problems raised by Quine have indeed been resolved by the possible worlds model theory. But I also claim – perhaps against common perception, but in line with Quine’s persisting fifty-year-old skepticism – that one problem of Quine’s original paper is still alive: the problem of interpreting modal logic. Surprisingly, Quine’s best ally on these matters turns out to be the very philosopher who engineered the possible worlds model theory: Saul Kripke. (shrink)

A major source of latter-day skepticism about necessity is the work of David Hume. Hume is widely taken to have endorsed the Humean claim: there are no necessary connections between distinct existences. The Humean claim is defended on the grounds that necessary connections between wholly distinct things would be mysterious and inexplicable. Philosophers deploy this claim in the service of a wide variety of philosophical projects. But Saul Kripke has argued that it is false. According to Kripke, there are (...) necessary connections between distinct existences; in particular, there are necessary connections between material objects and their material origins. In this paper I argue that the primary motivation for the Humean claim, Hume's datum, also motivates the key premise in an argument for the necessity of origins. The very considerations that the Humean takes to show that necessary connections between wholly distinct things would be mysterious and inexplicable indicate that there must be some such necessary connections. Thus, in the absence of alternative support, there is no reason to believe the Humean claim. (shrink)

The comments focus on a presumed circular reasoning in the operator hierarchy and the necessity of understanding life’s origin for defining life. Below it is shown that its layered structure prevents the operator hierarchy from circular definitions. It is argued that the origin of life is an insufficient basis for a definition of life that includes multicellular and neural network organisms.

In `Essence and Modality', Kit Fine proposes that for a proposition to be metaphysically necessary is for it to be true in virtue of the nature of all objects whatsoever. Call this view Fine's Thesis. This paper is a study of Fine's Thesis in the context of Fine's logic of essence (LE). Fine himself has offered his most elaborate defense of the thesis in the context of LE. His defense rests on the widely shared assumption that metaphysical necessity obeys (...) the laws of the modal logic S5. In order to get S5 for metaphysical necessity, he assumes a controversial principle about the nature of all objects. I will show that the addition of this principle to his original system E5 leads to inconsistency with an independently plausible principle about essence. In response, I develop a theory that avoids this inconsistency while allowing us to maintain S5 for meta- physical necessity. However, I conclude that our investigation of Fine's Thesis in the context of LE motivates the revisionary conclusion that metaphysical necessity obeys the principles of the modal logic S4, but not those of S5. I argue that this constitutes a distinctively essentialist challenge to the received view that the logic of metaphysical necessity is S5. (shrink)

In this splendid section from his Enquiry Concerning Human Understanding , Hume's first concern is our ordinary belief that the natural world -- the world leaving our own conscious existence aside -- is a world of determinism, all cause and effect. He gives his account of what this ordinary belief can come to, the fact of the matter. Turning to our own conscious existence, he finds the same fact of the matter. Hence our world too is a world of determinism, (...) all cause and effect. That is the story with the man who comes to dinner and does not rob Hume of his silver standish. The story of Indeterminism, and in particular of the kind of freedom that is origination, must be a mistake. (shrink)

A methodological model of origin and settlement of theory-choice situations (previously tried on the theories of Einstein and Lorentz in electrodynamics) is applied to modern Theory of Gravity. The process of origin and growth of empirically-equivalent relativistic theories of gravitation is theoretically reproduced. It is argued that all of them are proposed within the two rival research programmes – (1) metric (A. Einstein et al.) and (2) nonmetric (H. Poincare et al.). Each programme aims at elimination of the (...) cross-contradiction between the special theory of relativity and Newton’s theory of gravitation. New arguments in favor of Einstein’s programme are given. Nevertheless, this does not imply the necessity to rule out all the nonmetric theories, since Einstein’s and Poincare’s programmes are alternative only as different tools of the cross-contradiction elimination. In the other respects these programmes are complementary: description, explanation and prediction of gravitational experimental data entails the usage of the languages of nonmetric theories as well as of metric ones. The part of the present investigation elucidating the necessity of nonmetric theories is an implementation of the ideas of A.Z. Petrov, the founder of Kazan University Relativity Department. Late Alexei Zinovievich had frequently punctuated that the notion of Riemann space-time continuum common for all metric theories obfuscates all the gravitational notions considerably and hampers the analogies with other physical theories at hand. Since the ambiguity is a hallmark of all the general relativism notions, approach to their definitions “should be determined not by analogies and contingent facts, but by general considerations linked the physical measurements theory… No matter how far the events lie out of the frames of classical physical explanations, all the experimental data should be described by classical notions” (Petrov, 1965,pp. 59,66). Key words: Kip S. Thorne, A.P. Lightman, Stepin, theory of gravity . (shrink)

_ Source: _Volume 38, Issue 1, pp 106 - 128 This paper is interested in the critical potential of the idea of original common possession of the Earth. On the basis of a comparative analysis of Hugo Grotius and Immanuel Kant, it shows how different the meaning of this idea can be within a theory of property or territory. The first part is devoted to Grotius’s account of why and how the institution of property was progressively introduced. It highlights the (...) importance this account attaches to the intention of the first distributors for a good understanding of property laws, and in particular, for an understanding of their non-application in situations of extreme necessity. The second part takes the opposite path and shows that although Kant rejects the very existence of a right of necessity, the idea that one might be liberated from a law is not completely absent from, and even plays a crucial role in, his account of property. Clarification of this role ultimately leads us back to the idea of original possession in common of the Earth. (shrink)

The idea that the epistemology of modality is in some sense a priori is a popular one, but it has turned out to be difficult to precisify in a way that does not expose it to decisive counterexamples. The most common precisifications follow Kripke’s suggestion that cases of necessary a posteriori truth that can be known a priori to be necessary if true ‘may give a clue to a general characterization of a posteriori knowledge of necessary truths’. The idea is (...) that whether it is contingent whether p can be known a priori for at least some broad range of sentences ‘p’. Recently, Al Casullo and Jens Kipper have discussed restrictions of such principles to atomic sentences. We show that decisive counterexamples even to such dramatically restricted Kripke-style principles can be constructed using minimal logical resources. We then consider further restrictions, and show that the counterexamples to the original principles can be turned into counterexamples to the further restricted principles. We conclude that, if there are any true restrictions of Kripke-style principles, then they are so weak as to be of little epistemological interest. (shrink)

To differentiate between the laws of nature and accidental generalizations, we must adopt a view of necessity that is capable of being realized in relationships existing among natural objects. In neo-Sadraian Islamic philosophy, metaphysical necessity is accepted as part of the cause-effect relationship. This paper compares the neo-Sadraian interpretation of necessity and necessitarian theories about the laws of nature, particularly essentialism and universal theory. By resorting to specific forms al-shûrat al-naw’iyyah, the origin of the essential properties (...) of natural objects, I argue that neo-Sadraians have proposed a perspective on metaphysical necessity that is epistemologically a posteriori.

The origin of paraconsistent logic is closely related with the argument, ‘from the assertion of two mutually contradictory statements any other statement can be deduced’; this can be referred to as ex contradictione sequitur quodlibet (ECSQ). Despite its medieval origin, only by the 1930s did it become the main reason for the unfeasibility of having contradictions in a deductive system. The purpose of this article is to study what happened earlier: from Principia Mathematica to that time, when it (...) became well established. The two main historical claims that I am going to advance are the following: (1) the first explicit use of ECSQ as the main argument for supporting the necessity of excluding any contradiction from deductive systems is to be found in the first edition of the book Grundzüge der Theoretischen Logik (Hilbert, D. and Ackermann, W. 1928. Grundzüge der Theoretischen Logik. Berlin: Julius Springer Verlag); (2) Łukasiewicz's position regarding the logical constraints against contradictions varies considerably from his studies on the principle of (non-) contradiction in Aristotle, published in 1910 and what is stated in his `authorized lectured notes' on mathematical logic that appeared in 1929. The two texts are: 1) a paper in German (Łukasiewicz, J. 1910. `Über den Satz des Widerspruchs bei Aristotles'. Bulletin International de l'Académie des sciences de Cracovie, Classe d'Histoire et de Philosophie, pp. 15–38) [English translation: Łukasiewicz, J. 1971. ‘On the principle of contradiction in Aristotle’, Review of Metaphysics, XXIV, 485–509]; and 2) a book in Polish. Łukasiewicz, J. 1910. O zasadzie sprzecznosci u Aristotelesa Studium krytyczne, Warsaw: Panstwowe Wydawnictwo Naukowe [German translation: Łukasiewicz, J. 1993. Über den Satz des Widerspruchs bei Aristotles. Hildesheim: Georg Olms Verlag]. The lecture notes were then published as a book (Łukasiewicz, J. 1958. Elementy Logiki Matematycznej. Warszawa: Panstwowe Wydawnictwo Naukowe [PWN] and then translated into English (Łukasiewicz, J. 1963. Elements of Mathematical Logic. Oxford, New York: Pergamon Press/the Macmillan Company). The second half of this article will concentrate on Łukasiewicz's position on ECSQ. This will lead me to propose that to regard him as a forerunner of paraconsistent logic by virtue of those early writings is accurate only if his book published in Polish is considered but not if the analysis is restricted to the paper originally published in German (as has been the case for the principal reconstructions of the history of paraconsistent logic). Furthermore, I will stress that in the 1929 book he presented one formalization of ECSQ as an axiom for sentential calculus and, also, he used ECSQ to defend the necessity of consistency, apparently independently of Hilbert and Ackermann's book. At the end, I will suggest that the aim of twentieth century usage of ECSQ was to change from the centuries-long philosophical discussion about contradictions to a more ‘technical’ one. But with paraconsistent logic viewed as a technical solution to this restriction, then, the philosophical problem revives but having now at one's disposal an improved understanding of it. Finally, Łukasiewicz's two different positions about ECSQ open an interesting question about the history of paraconsistent logic: do we have to attempt a consistent reconstruction of it, or are we prepared to admit inconsistencies within it?

A discussion of Aristotle’s thought on determinism and culpability, Necessity, Cause, and Blame also reveals Richard Sorabji’s own philosophical commitments. He makes the original argument here that Aristotle separates the notions of necessity and cause, rejecting both the idea that all events are necessarily determined as well as the idea that a non-necessitated event must also be non-caused. In support of this argument, Sorabji engages in a wide-ranging discussion of explanation, time, free will, essence, and purpose in nature. (...) He also provides historical perspective, arguing that these problems remain intimately bound up with modern controversies. “ Necessity, Cause and Blame would be counted by all as one of Sorabji’s finest. The book is essential for philosophers—both specialists on the Greeks and modern thinkers about free will—and also compelling for non-specialists.”—Martha Nussbaum “Original and important . . . The book relates Aristotle’s discussions to both the contemporary debates on determinism and causation and the ancient ones. It is especially detailed on Stoic arguments about necessity . . . and on the social and legal background to Aristotle’s thought.”— Choice “It is difficult to convey the extraordinary richness of this book. . . . A Greekless philosopher could read it with pleasure . . . At the same time, its learning and scholarship are enormous.”—G. E. M. Anscombe, Times Literary Supplement. (shrink)
