The analytic movement advertised its 'linguistic turn' as a radical break from the two-thousand-year-old substance tradition. But this is an illusion. On the fundamental level of ontology, there is enough reformulation and presupposition of traditional 'no entity without identity' themes to analogize Frege, Russell, Wittgenstein, and Quine to Aristotle as paradigmatic of modified realism. Thus the pace of ontology is glacial. Frege and Russell, not Wittgenstein and Quine, emerge as the true analytic progenitors of 'no entity without identity,' offering between (...) them at least twenty-nine private language arguments and sixty-four 'no entity without identity' theories.

Prominent thinkers such as Kripke and Rescher hold that Russell has no modal logic, even that Russell was indisposed toward modal logic. In Part I, I show that Russell had a modal logic which he repeatedly described and that Russell repeatedly endorsed Leibniz's multiplicity of possible worlds. In Part II, I describe Russell's theory as having three ontological levels. In Part III, I describe six Parmenidean theories of being Russell held, including: literal in 1903; universal in 1912; timeless in 1914; (...) transcendental in 1918–1948. The transcendental theory underlies the primary level of Russell's modal logic. In Part IV, I examine Rescher's view that Russell and modal logic did not mix. (shrink)

I SHOW THAT THE COSMOLOGICAL ARGUMENT OF AQUINAS FOR THE EXISTENCE OF GOD COMMITS A RATHER TRIVIAL LINGUISTIC FALLACY, BY SHOWING THAT (1) SOME OF ZENO'S PARADOXES COMMIT A TRIVIAL LINGUISTIC FALLACY, AND THAT (2) THE COSMOLOGICAL ARGUMENT IS SUFFICIENTLY SIMILAR TO THESE PARADOXES THAT IT COMMITS THE SAME FALLACY. COPLESTON'S VIEW THAT "MENTION OF THE MATHEMATICAL INFINITE SERIES IS IRRELEVANT" TO "ANY" OF AQUINAS'S ARGUMENTS FOR GOD'S EXISTENCE IS THUS SHOWN FALSE.

This paper continues Michael Dummett's and my discussion of Frege in The Philosophy of Michael Dummett [2007]. Most of it is about Dummett’s change in view on Frege’s senses and objects. The issues include: the cognitive order versus the ontological order for the forward road; the nature and identity of senses and the different senses of "intension;" the nature of saturation; whether special quantifiers are now needed for senses; and Frege’s earlier and later permutation arguments. I discuss the implications of (...) the forward road for intuitionism as well. (shrink)

Do any significant philosophical differences between Quine and Carnap follow from Quine’s rejection of Carnap’s analytic-synthetic distinction? Not if they both understand empirical evidence in merely observational terms. But it follows from Quine’s rejection of the distinction that empirical evidence has degrees of holophrastic depth penetrating even into logic and ontology (gradualism). Thus his reasons to prefer realism to idealism are holophrastically empirical. I discuss Quine’s holist sectarian realism on private languages, externalism versus internalism, unobserved objects, unobservable abstract entities, bivalence, (...) ecumenicism versus sectarianism, and on gradualism itself.

What is logical relevance? Anderson and Belnap say that the “modern classical tradition [,] stemming from Frege and Whitehead-Russell, gave no consideration whatsoever to the classical notion of relevance.” But just what is this classical notion? I argue that the relevance tradition is implicitly most deeply concerned with the containment of truth-grounds, less deeply with the containment of classes, and least of all with variable sharing in the Anderson–Belnap manner. Thus modern classical logicians such as Peirce, Frege, Russell, Wittgenstein, and (...) Quine are implicit relevantists on the deepest level. In showing this, I reunite two fields of logic which, strangely from the traditional point of view, have become basically separated from each other: relevance logic and diagram logic. I argue that there are two main concepts of relevance, intensional and extensional. The first is that of the relevantists, who overlook the presence of the second in modern classical logic. The second is the concept of truth-ground containment as following from in Wittgenstein’s Tractatus. I show that this second concept belongs to the diagram tradition of showing that the premisses contain the conclusion by the fact that the conclusion is diagrammed in the very act of diagramming the premisses. I argue that the extensional concept is primary, with at least five usable modern classical filters or constraints and indefinitely many secondary intensional filters or constraints. For the extensional concept is the genus of deductive relevance, and the filters define species. Also following the Tractatus, deductive relevance, or full truth-ground containment, is the limit of inductive relevance, or partial truth-ground containment. Purely extensional inductive or partial relevance has its filters or species too. Thus extensional relevance is more properly a universal concept of relevance or summum genus with modern classical deductive logic, relevantist deductive logic, and inductive logic as its three main domains.

This paper continues my discussion with Michael Dummett on Frege’s senses, published in The Philosophy of Michael Dummett and further developed in Diametros. In his reply to my original paper, Dummett came to agree with me that senses are neither objects nor functions, since they have a categorially different kind of linguistico-metaphysical function to perform. He then asks how we might quantify over senses, if they are neither objects nor functions. He discusses two main options, and finds one unviable and (...) the other “very un-Fregean.” I then offer a Fregean or neo-Fregean option in my rejoinder. And I still hold that this way out will do the job, or is at least plausible enough that the burden of persuasion is on those who disagree. But I hope to show in this paper that on a more complete examination of Frege, there are at least twenty Fregean or neo-Fregean ways out, with the one I proposed being option. (shrink)

[Jan Dejnožka: The Ontology of the Analytic Tradition.and Its Origins].

Existuje překvapivě málo knih, které by se pokoušely o syntetizující pohled na analytickou filosofii. Je ovšem pravda, že ve druhé polovině našeho století se soubor filosofů, kteří se k analytické filosofii hlásí nebo kteří k ní bývají řazeni, stává natolik různorodý, že se jakákoli syntéza stává problematickou; překvapivě málo syntetizujících prací existuje ale i o ‘klasické’ analytické filosofii, to jest o analytické filosofii období zhruba od konce devatenáctého století do poloviny století dvacátého. Dejnožkova kniha je jednou z těch mála, které (...) se o něco takového pokouší, a to je třeba přivítat. Dejnožka se ovšem nesnaží podat všestranný rozbor názorů klasiků analytické filosofie; soustředí se pouze jeden aspekt jejich učení, totiž na jejich ontologii. Hned v úvodu své knihy k tomu vysvětluje, jaké opodstatnění může mít hovořit o ontologii u takového druhu filosofie, která se programově distancuje od metafyziky. Podle něj je tomu tak, že i když se někteří analytičtí filosofové někdy více či méně úspěšně vyhýbali otázkám metafyzickým (to jest otázkám po nejzákladnějších kategoriích bytí), ontologickým otázkám (to jest otázkám po povaze bytí jako takového) se v podstatě vyhnout nelze. A Dejnožka se snaží ukázat, že klasikové analytické filosofie se těmito otázkami zabývali mnohdy velice do hloubky. To je patrné zejména u Frega a Russella, kterým autor věnuje největší pozornost; avšak k těm, kteří podle Dejnožky berou ústřední otázku ontologie za svou, řadí Dejnožka i Wittgensteina i Quina (jimž se však věnuje na pouze velice omezeném prostoru - každému asi na dvanácti stránkách).

This is a critical review of a book that defends two basic theses about analytic philosophy--that the 'no entity without identity' ontology is basic to the four great analytic philosophers and that they were 'modified realists.' This review calls into question both of these claims. The ontological views of Frege, Russell, Quine, Wittgenstein and others are discussed as well other central issues in analytic philosophy.

In lieu of an abstract, here is a brief excerpt of the content:66 Discussion REJOINDER TO DEJNOZKA'S REPLY GARY OSTERTAG Philosophy/ New YorkU. New York,NY 10003, USA [email protected] It is common knowledge that Russell does not explicitly endorse modal logic in any of his major logical writings. Nor does my review of BertrandRusseli onModalityand LogicalRelevance' suggest that Jan Dejnozka denies or is somehow unaware of this. On the contrary, I assume it to be obvious that any commitment Russell (...) may have had to modal logic must be implicitin his writings, nor explicit. The real issue is whether there is evidence of any such commitment. I will state, briefly,why I remain sceptical. First, Dejnozka's book lacks any interpretive methodology. When the question arises, In whichcontextsis itpermissibleto translateRusseli's language(formal orinformal)intoa modalsystem?, we get the following: amibute a modal logic to Russell if "it is more reasonable than not to paraphrase Russell's thinking into the modal logic." This condition, we are told, "is met to the extent that acertain modal logic is logicallyimplicit in Russell's thinking." All of which goes without saying, but it simply delays the inevitable question: when is a modal logic logicallyimplicit in a text? Dejnozka's current answer: a modal logic is logically implicit in a text when the text logically implies the paraphrase.2 But the final suggestion is incoherent, since we cannot tell what a text logical1y implies until we have discerned its logicalform-i.e. until we havealready paraphrased it into some formal idiom or other. A related problem is that Dejnozka consistently failsto distinguish two sorts of claims: • Certain passagesin Russell lend themselves to a modal interpretationthey can be captured in a given system of modal logic, e.g. S13. • Such an interpretation reflects Russell'sintentions. That a modal system captures one or another of Russell's accounts of logical truth in itself entails nothing regarding Russell'sintentions. The modal system G described by George Boolos in a munber of publications provides an alterna- ' "Russell's Modal Logic?", Russelin.s. 20 (2000): 165-72. 2 "Reply to Ostertag", Russell, n.s. 21 (2001): 63-5 (at 65). Discussion 67 rive formalization of Peano Arithmetic, enabling the derivation of Godel's incompleteness theorems. Yet the fact that this is possible does not in any way suggest that Godel himself was implicitly committed to G. Unfortunately, Dejnozka often writes as if the mere possibility of a modal interpretation is genuinely revealing as to Russell's intemions. Bm it is just as implausible to maintain this as it is to claim that it was Gi:idel'sintention to present Boolos's G.3 Second, as I maintain in my review, Dejnozka fails to take seriously the many comexts in which Russell is explicitly critical of modality. Dejnozka responds that he has quoted these very passagesand that he "embraces them as half-but only half-of [his] basic message" ("Reply", p. 64). But citing contexts in which Russell appears to find modality congenial does nothing to mitigate the force of the contexts in which Russell explicitly repudiates modality. It is Dejnozka's responsibility to explain how the latter are to cohere with his interpretation. To avoid this issue is to skirt the real philosophical and interpretive challenge that the project entails. Finally, we come to Dejnozka's confusions surrounding MDL-the triad of equivalences that underwrite the interpretation of Principiaas a modal logic. In light of Dejnozka's steadfast refusal to formalize the various modal systems he amibmes to Russell, it hardly makes a differencewhether MDLis a modal logic or merely, to use his terminology, a "modal theory" (assuming that the latter ultimately amounts to something other than a modal logic).4What is importam is whether MDLis trivial. If it is, then it is quite beside the point to pursue the various extensions of MDL.Since I maimain that Russell is not commined, implicitly or otherwise, to a substantive reading of MDL-one in which the modal operators have their conventional meanings-then he is not committed to these extensions, so there is no need for detailed discussion. What remains central is my argtunent for the claim that MDL is trivial. Bm this argmnent (unacknowledged by Dejnozka) is there for... (shrink)

It can be tempting to think of affect as a matter of the present moment – a reaction, a feeling, an experience or engagement that unfolds right now. This paper will make the case that affect is better thought of as not only temporally extended but as saturated with temporality, especially with the past. In and through affectivity, concrete, ongoing history continues to weigh on present comportment. In order to spell this out, I sketch a Heidegger-inspired perspective. It revolves around (...) two claims. The first is that we should understand what Heidegger calls 'Befindlichkeit' (findingness) as radical situatedness. Affectivity is a matter of 'finding oneself' constellated – thrown – into the world in ways that outrun what an individual or collective might grasp and process. The second claim is that the temporal dimension, as a relatedness to the past, takes precedence in affect's situatedness. Key to affect is the way in which the past continues to hold sway over present comportment, collectively and individually. In order to articulate this perspective, it is important to overcome the idea that affect must be understood mainly in terms of feeling or experiential states of other kinds. Better suited to grasp the idea of findingness is the concept of 'disclosive posture', as proposed by Katherine Withy. I suggest that this notion should be put at the fore of a phenomenological approach to situated affectivity. (shrink)

Epigenetics is currently one of the fastest-growing fields in the sciences. Epigenetic information not only controls DNA expression but links genetic factors with the environmental experiences that influence the traits and characteristics of an individual. What we eat, where we work, and how we live affects not only the activity of our genes but that of our offspring as well. This discovery has imposed a revolutionary theoretical shift on modern biology, especially on evolutionary theory. It has helped to uncover the (...) developmental processes leading to cancer, obesity, schizophrenia, alcoholism, and aging, and to facilitate associated medial applications such as stem cell therapy and cloning. Above the Gene, Beyond Biology explores how biologists in this booming field investigate and explain living systems. Jan Baedke offers the first comprehensive philosophical discussion of epigenetic concepts, explanations, and methodologies so that we can better understand this "epigenetic turn" in the life sciences from a philosophical perspective.

The paper examines the interplays between logic and politics in the Polish School of Logic starting from 1914. The Polish School of Logic flourished between 1920 and 1939. Philosophically, it was influenced by Kazimierz Twardowski (1866–1938). For Twardowski logic is fundamental for every kind of human activity, professional and private and this means that every argument should be formulated and proceed by correct inferential rules. These rules involve semiotics, formal logic and methodology of science. The paper shows how this position (...) was shared by Twardowski’s students, including Jan Łukasiewicz, Stanisław Leśniewski, Kazimierz Ajdukiewicz and Tadeusz Kotrabiński, as well as by the next generation of logicians and philosophers and especially by Alfred Tarski. These authors considered logic, philosophy and science as completely neutral with respect to politics and ideology but they also considered logical skills as indispensable in political activities.

Higher-order logic, with its type-theoretic apparatus known as the simple theory of types (STT), has increasingly come to be employed in theorizing about properties, relations, and states of affairs—or ‘intensional entities’ for short. This paper argues against this employment of STT and offers an alternative: ordinal type theory (OTT). Very roughly, STT and OTT can be regarded as complementary simplifications of the ‘ramified theory of types’ outlined in the Introduction to Principia Mathematica (on a realist reading). While STT, understood as (...) a theory of intensional entities, retains the Fregean division of properties and relations into a multiplicity of categories according to their adicities and ‘input types’ and discards the division of intensional entities into different ‘orders’, OTT takes the opposite approach: it retains the hierarchy of orders (though with some modifications) and discards the categorisation of properties and relations according to their adicities and input types. In contrast to STT, this latter approach avoids intensional counterparts of the Epimenides and related paradoxes. Fundamental intensional entities lie at the base of the proposed hierarchy and are also given a prominent part to play in the individuation of non-fundamental intensional entities. (shrink)

By and large, the conditional connective in three-valued logic has two different functions. First, by means of a deduction theorem, it can express a specific relation of logical consequence in the logical language itself. Second, it can represent natural language structures such as "if/then'' or "implies''. This chapter surveys both approaches, shows why none of them will typically end up with a three-valued material conditional, and elaborates on connections to probabilistic reasoning.

International institutions such as UNESCO are deliberating on a new standard setting instrument for neurotechnologies. This will likely lead to the adoption of a soft law document which will be the first global document specifically tailored to neurotechnologies, setting the tone for further international or domestic regulations. While some stakeholders have been consulted, these developments have so far evaded the broader attention of the neuroscience, neurotech, and neuroethics communities. To initiate a broader debate, this target article puts to discussion twenty-five (...) considerations and desiderata for recognition by a future instrument. They are formulated at different levels of abstraction, from the big picture to technical details, seek to widen the perspective of preparatory reports and transcend the narrow debate about “neurorights” which overshadows many richer and more relevant aspects. These desiderata are not an exhaustive enumeration but a starting point for discussions about what deserves and what requires protection by an international instrument. (shrink)

Evidence-Based Medicine has little consideration for mechanisms and philosophers of science and medicine have recently made pleas to increase the place of mechanisms in the medical evidence hierarchy. However, in this debate the notions of mechanisms seem to be limited to 'mechanistic processes' and 'complex-systems mechanisms,' understood as 'componential causal systems'. I believe that this will not do full justice to how mechanisms are used in biological, psychological and social sciences and, consequently, in a more biopsychosocial approach to medicine. Here, (...) I propose, following (Kuorikoski, 2009), to pay more attention to 'abstract forms of interaction' mechanisms. The present work scrutinized review articles on depression and medically unexplained pain, which are considered to be of multifactorial pathogenesis, for their use of mechanisms. In review articles on these disorders there seemed to be a range of uses between more 'abstract forms of interaction' and 'componential causal system' mechanisms. I therefore propose to expand the notions of mechanisms considered in medicine to include that of more 'abstract forms of interaction' to better explain and manage biopsychosocial disorders.

We introduce a cyclic proof system for the two-way alternation-free modal μ-calculus. The system manipulates one-sided Gentzen sequents and locally deals with the backwards modalities by allowing analytic applications of the cut rule. The global effect of backwards modalities on traces is handled by making the semantics relative to a specific strategy of the opponent in the evaluation game. This allows us to augment sequents by so-called trace atoms, describing traces that the proponent can construct against the opponent’s strategy. The (...) idea for trace atoms comes from Vardi’s reduction of alternating two-way automata to deterministic one-way automata. Using the multi-focus annotations introduced earlier by Marti and Venema, we turn this trace-based system into a path-based system. We prove that our system is sound for all sequents and complete for sequents not containing trace atoms. (shrink)

Niels Bohr and Philosophy of Physics: Twenty-First Century Perspectives examines the work, influences and legacy of the Nobel Prize physicist and philosopher of experiment Niels Bohr. While covering Bohr's groundbreaking contribution to quantum mechanics, this collection reveals the philosophers who influenced his work. Linking him to the pragmatist C.I. Lewis and the Danish philosopher Harald Høffding, it draws strong similarities between Bohr's philosophy and the Kantian way of thinking. Addressing the importance of Bohr's views of classical concepts, it discusses how (...) his interpretation of quantum mechanics now compares with a variety of issues that have arisen only since his lifetime, including decoherence and other non-collapse arguments. Balancing historical themes with contemporary ideas, Niels Bohrs and Philosophy of Physics reveals Bohr's on-going contribution to the philosophy of science and confirms his place in the history of philosophy.

A number of well-developed theories shed light on the question, under what circumstances our beliefs enjoy epistemic justification. Yet, comparatively little is known about epistemic defeat--when new information causes the loss of epistemic justification. This book proposes and defends a detailed account of epistemic defeaters. The main kinds of defeaters are analyzed in detail and integrated into a general framework that aims to explain how beliefs lose justification. It is argued that defeaters introduce incompatibilities into a noetic system and thereby (...) prompt a structured re-evaluation process that makes a justified reinstatement of the defeated belief impossible. The account is then applied to the topic of disagreement, where it is used in an argument for conciliationism, as well as a new explanation for higher-order defeat. Throughout the book, the notion of defeat is the center of attention, while a number of new issues are discussed at the intersections of defeat and justification. Specifically, new problems are raised for broadly internalist accounts of defeat, a fully descriptive reliabilist account of defeat is provided, and the case for normative defeat is revisited.
