Marie Duží St. Anselm’s Ontological Arguments
abstract | view |  rights & permissions
In the paper I analyse Anselm’s ontological arguments in favour of God’s existence. The analysis is an explication and formalization of Pavel Tichý’s study‘Existence and God’, Journal of Philosophy, 1979. It is based on Transparent Intensional Logic with its bi-dimensional ontology of entities organized in the ramified hierarchy of types. The analysis goes as follows. First, necessary notions and principles are introduced. They are: (a) existence is not a (non-trivial) property of individuals, but of individual offices to be occupied by an individual; (b) the notion of requisite is defined, which is a necessary relation between an office O and a property R: necessarily, if a happens to occupy O then a has the property R. (c) I demonstrate that an argument of the form “R is a requisite of O, hence the holder of O has the property R” is invalid. In order to be valid, it must be of the form “R is a requisite of O, the office O is occupied, hence the holder of O has the property R.” Finally, (d) higher-order offices that can be occupied by individual offices are defined. Their requisites are properties of individual offices. Then the analysis of Anselm’s arguments is presented. The expression ‘God’ denotes an individual office, a ‘thing to be’, rather than a particular individual. Thus the question whether God exists is a legitimate one. I analyze the expression ‘that, than which nothing greater can be conceived’. Since ‘greater than’ is a relation-in-intension between individual offices here, the expression denotes a second-order office, and its requisites are properties of first-order offices suchas necessary existence. The second of Anselm’s assumptions is that individual office that has the property of necessary existence is greater than any other office lacking this property. From these it follows that the first-order holder of the office denoted by ‘that, than which nothing greater can be conceived’ (that is God) enjoys the property of necessary existence. Thus God exists necessarily, hence also actually. Anselm’s argument is logically valid. If it were also sound, then an atheist would differ from a believer only by the former not believing whereas the latter believing in a tautology, which is absurd. Yet we may doubt the validity of Anselm’s assumption that a necessary existence makes an office greater than any other office lacking this property.

Stephen Palmquist The Kantian Grounding of Einstein’s Worldview: (II) Simultaneity, Synthetic Apriority and the Mystical
abstract | view |  rights & permissions
Part I in this two-part series employed a perspectival interpretation to argue that Kant’s epistemology serves as the philosophical grounding for modern revolutions in science. Although Einstein read Kant at an early age and immersed himself in Kant’s philosophy throughout his early adulthood, he was reluctant to admit Kant’s influence, possibly due to personal factors relating to his cultural-political situation. This sequel argues that Einstein’s early Kant-studies would have brought to his attention the problem of simultaneity and the method of solving it that eventually led to the theory of relativity. Despite Einstein’s reluctance to acknowledge his Kantian grounding, a perspectival understanding of Kant’s philosophy of science shows it is profoundly consistent with Einstein’s views on both synthetic apriority and the nature of scientific theory. Moreover, Kant and Einstein share quasi-mystical religious tendencies, relying on an unknowable absolute as the ultimate boundary of our scientific understanding of nature.

Stamatios Gerogiorgakis Omniscience in Łukasiewicz’s, Kleene’s and Blau’s Three-Valued Logics
abstract | view |  rights & permissions
In this paper several assumptions concerning omniscience and future contingents on the one side, and omniscience and self-reference on the other, areexamined with respect to a classical and a three-valued semantic setting (the latter pertains especially to Łukasiewicz’s, Kleene’s and Blau’s three-valued logics).Interesting features of both settings are highlighted and their basic assumptions concerning omniscience are explored. To generate a context in which the notion of omniscience does not deviate from some basic intuitions, two special futurity operators are introduced in this article: one for what will definitely take place and another one for what is indeterminate as to whether it will take place. Once these operators are introduced, some puzzles about omniscience in combination with future contingents are removed. An analogous solution to some puzzles concerning omniscience and selfreferentiality is also provided.

Danny Frederick P.F. Strawson on Predication
abstract | view |  rights & permissions
Strawson offers three accounts of singular predication: a grammatical, a category and a mediating account. I argue that the grammatical and mediating accounts are refuted by a host of counter-examples and that the latter is worse than empty. In later works Strawson defends only the category account. This account entails that singular terms cannot be predicates; it excludes non-denoting singular terms from being logical subjects, except by means of an ad hoc analogy; it depends upon a notion of identification that is too vague; and it is unnecessarily complicated, relying on analogies where a more uniform explanation should be possible. But I show how the account can be corrected to avoid all these difficulties and to provide an accurate account of singular predication.

Leopold Hess Superessentialism and Necessitarianism: Between Spinoza and Lewis
abstract | view |  rights & permissions
The paper concerns mutual relations between two metaphysical positions: “superessentialism,” claiming that all properties of every object are essential, i.e.necessary, and “necessitarianism,” claiming that everything is necessary, i.e. there is only one possible world. The theories of Spinoza and Lewis serve as examples. In section I the two positions are characterized. In section II and III interpretations of Spinoza’s and Lewis’s metaphysics are presented, and it is explained to what extent they can both be considered superessentialists and necessitarians. In section IV the two theories are compared. In section V three possible ways of arguing for superessentialism are presented. It is then shown that the premises of these arguments appear, at least implicitly, in both of the theories. In section VI additional premises are numbered which have to be further assumed to prove necessitarianism. In the final section it is shown how Lewis can claim that there are contingent facts, while being a superessentialist and a necessitarian. It is argued that his claim of contingency is a matter of semantics, not of metaphysics.

Lotar Rasiński Power, Discourse, and Subject. The Case of Laclau and Foucault
abstract | view |  rights & permissions
In this text the author draws on two contemporary accounts of power—by Michel Foucault and Ernesto Laclau—and, on the basis of thorough analysis and comparison, he argues for “the discursive account of power” (DAP) as a new concept reflecting the novel approach to the theory of power developed by these two philosophers. He opens with a broad methodological outline of contemporary concepts of power, distinguishing between the “classical” and the “modern” approaches. Basing his findings on Laclau’s and Foucault’s work, he then presents DAP as a theory characterized by decentralizing, non-normative, and conflict-based tendencies that does not exhibit many of the limitations that usually characterize both classical and modern concepts of power. In the second part of the article the author presents a detailed methodological analysis of Foucault’s and Laclau’s concepts of power, focusing on three axes: power, discourse, and the subject. The author dedicates the last section to a comparison of both approaches, concluding that DAP is an inspiring project that exceeds the limits of traditional liberal theories of power and politics.

Rafe McGregor Cinematic Realism Reconsidered
abstract | view |  rights & permissions
The purpose of this paper is to re-examine the debate about cinematic motion in terms of the necessity for reception conditions in art. I shall argue that Gregory Currie’s rejection of weak illusionism—the view that cinematic motion is illusory—is sound, because cinematic images really move, albeit in a response-dependentrather than garden-variety manner. In §1 I present Andrew Kania’s rigorous and compelling critique of Currie’s realism. I assess Trevor Ponech’s response to Kania in §2, and show that his focus on the cinematic experience is indicative of the direction the debate should take. §3 demonstrates that the issue is underpinned by the question of the role of reception conditions in the experience of art. In §4 I apply my observations on reception conditions to the problem of cinematic motion and conclude that Kania’s objections are unsuccessful due to his failure to acknowledge the necessary conditions for cinematic experience.

M. Fletcher Maumus Proper Names: Attribution and Reference
abstract | view |  rights & permissions
Principally under the influence of Saul Kripke (1972), philosophical semantics since the closing decades of 20th century has been dominated by thephenomenon Nathan Salmon (1986) aptly dubbed Direct Reference “mania.” Accordingly, it is now practically orthodox to hold that the meanings of proper names are entirely exhausted by their referents and devoid of any descriptive content. The return to a purely referential semantics of names has, nevertheless, coincided with a resurgence of some of the very puzzles that motivated description theories of names in the first place, to wit: the informativeness of true identity statements of the form ‘a=b’ and the failure of substitutivity salve veritate for co-referential names in propositional attitude ascriptions. I argue that a Metalinguistic Description Theory of proper names, which treats the meaning of an arbitrary proper name as roughly equivalent to the definite description ‘the bearer of NN,’ offers a novel, semantically innocent solution to these puzzles when synthesized with Keith Donnellan’s (1966) insight that descriptions are semantically ambiguous between attributive and referential meanings. The ensuing account is then defended against two well-known Kripkean objections to metalinguisticsemantics: the Circularity Objection and the Paderewski Puzzle.

Robert S. Colter Thought, Perception, and Isomorphism in Aristotle’s De Anima
abstract | view |  rights & permissions
Aristotle contends that in perception the sense organ is “made like” its object, but only “in a certain way.” Much controversy has surrounded these remarks, primarily about how to understand being “made like.” One camp has understood this to require literal exemplification, such that the sense organs manifest the sensible qualities of their objects. Others have understood likeness to require no physical alteration at all in the sense organs.I accept as a starting point in this paper that understanding perceptual likeness in terms of exemplification is a non-starter. By doing so, however, I also reject the easiest and most direct understanding of what it means for the sense organs to be “made like” their objects. Others who have shared this assumption have suggested that likeness consists in “isomorphism.” Unfortunately, they have not adequately explicated how this notion is to be understood, with the result that Aristotle’s theory of perception remains crucially underdeveloped. I argue that the key is to understand the form of isomorphism at work in Aristotle’s account of thinking.

Karol Chrobak What Plurality of Realities? Some Critical Remarks on the Philosophy of Leon Chwistek
abstract | view |  rights & permissions
This paper focuses on the theory of plurality of realities introduced by Leon Chwistek. A critical analysis of this theory and an extensional interpretation of Chwistek’s axiomatic descriptions of four realities lead to an epistemological interpretation of this theory. The word “plurality” in the title is a result of different waysof understanding the same original set of sense-data. This interpretation is contrasted with Kazimierz Pasenkiewicz’s ontological version of this theory. In the final parts of the paper the most important consequences of this theory are discussed. First, the ethical relativism postulated by Chwistek is criticized. Second, an attempt to illustrate the plurality of realities with an example of different styles of painting is discussed. Third, a critical rationalism in the form of a kind of practical attitude toward social reality, which results from the theory of plurality of realities, is outlined.

Hartley Slater Logic is not Mathematical
abstract | view |  rights & permissions
I first show in this paper how twentieth century Set Theory got into its greatest tangle by, amongst other things, regarding relational remarks like ‘Rxy’ asbinary functions. I then show how the lack of indexicality, and of ‘that’-clauses, in Modern Logic led that subject into its intractable difficulties with the Theory of Truth. Both errors arose not only through a contempt for ordinary language, but also through the related failure to recognise that being logical is not a matter of being brainy, but of being coherent. It is not a mathematical talent, but a literary one. Later in the paper I go on to demonstrate this same conclusion with respect to Modal Logic and General Intensional Logic, and in particular with respect to fictions, since these are the central items that have been misunderstood, as is witnessed in some recent writings of Graham Priest.

Martin F. Fricke Rules of Language and First Person Authority
abstract | view |  rights & permissions
This paper examines theories of first person authority proposed by Dorit Bar-On (2004), Crispin Wright (1989a) and Sydney Shoemaker (1988). What all threeaccounts have in common is that they attempt to explain first person authority by reference to the way our language works. Bar-On claims that in our language selfascriptions of mental states are regarded as expressive of those states; Wright says that in our language such self-ascriptions are treated as true by default; and Shoemaker suggests that they might arise from our capacity to avoid Moore-paradoxical utterances. I argue that Bar-On’s expressivism and Wright’s constitutive theory suffer from a similar problem: They fail to explain how it is possible for us to instantiate the language structures that supposedly bring about first person authority. Shoemaker’s account does not suffer from this problem. But it is unclear whether the capacity to avoid Moore-paradoxical utterances really yields self-knowledge. Also, it might be that self-knowledge explains why we have this capacity rather than vice versa.

Alfredo Tomasetta Knowledge of Metaphysical Necessity. A Remark on Williamson
abstract | view |  rights & permissions
According to Williamson’s epistemology of modality, we know metaphysical necessities by means of our knowledge of some specific counterfactualconditionals. In particular, Williamson’s idea is that we come to have knowledge of metaphysical necessities—which have the form □A—via our knowledge ofcounterfactual conditionals which have the form ~A□→┴. In this paper I claim that there are two different ways in which Williamson’s position can plausibly bearticulated, and that both ways lead to circularity.

Clayton Peterson, Jean-Pierre Marquis A Note on Forrester’s Paradox
abstract | view |  rights & permissions
In this paper, we argue that Forrester’s paradox, as he presents it, is not a paradox of standard deontic logic. We show that the paradox fails since it is the result of a misuse of (ROM), a derived rule in the standard systems. Before presenting Forrester’s argument against standard deontic logic, we will briefly expose the principal characteristics of a standard system Δ. The modal system KD will be taken as a representative. We will then make some remarks regarding (ROM), pointing out that its use is restricted to the standard system’s theorems, and cannot be applied to contingent conditionals. Finally, we will show that Forrester’s paradox is not a paradox of standard deontic logic, at least not in the sense he intended it to be. We show that the paradox cannot arise in KD since its semantical model is not rich enough to represent the intuitive (informal) validity of the conditional within Forrester’s paradox. We show that the paradox arises within a system that has a finer semantics.

Alexander James Gillett Blurring: Structural Realism and the Wigner Puzzle
abstract | view |  rights & permissions
Investigating the metaphysical problem of nature requires engaging with philosophy of science. Arguments in this field, combined with metaphysical underdetermination problems in fundamental physics, have given rise to a sophisticated form of scientific realism called ontic structural realism; and the reconceptualisation of metaphysics in terms of structures. This transforms the problem of nature into the dissolution of the distinction between mathematical andphysical structures (what we shall call the “blurring problem”). To date, there has been an insufficient exploration of this problem in the literature because it has been deemed unscientific. This essay demonstrates that the problem is legitimate, important, and connects with a wider issue in the philosophy of mathematics—namely, the problem of applicability of mathematics to the sciences’ investigation of nature (the Wigner Puzzle).

Daniel Rönnedal Bimodal Logic
abstract | view |  rights & permissions
Many interesting philosophical principles include two kinds of modalities, e.g. epistemic and doxastic, alethic and epistemic, or alethic and deontic modalities.The purpose of this essay is to describe a set of bimodal systems, i.e. systems that include two kinds of modal operators, in which it is possible to investigate some formalizations of such principles. All in all we will consider 4,194,304 logics. All logics are described semantically and proof theoretically. We use possible world semantics to characterize the logics semantically, and both axiomatic systems and semantic tableaux to characterize them proof theoretically. We show that all systems are sound and complete with respect to their semantics and we consider some relationships between the various systems.

Andrzej Biłat Dubito ergo non sum or the Logic of Skepticism
abstract | view |  rights & permissions
The paper analyses three versions of skepticism: (1) the attitude of a general withholding of belief; (2) the attitude of general doubt and (3) the view that all beliefs are unjustified. It is shown on the basis of epistemic logic that only the first of these versions can be deemed not to be self-contradictory.

Renata Ziemińska Pragmatic Inconsistency of Sextan Skepticism
abstract | view |  rights & permissions
Skepticism described by Sextus Empiricus faces the persistent charge that it is an inconsistent, self-refuting view. However, recently its consistency hasbeen defended in three important ways: (1) it is a thesis with weak assertion, (2) it is a practice without any assertion, and (3) it is a process developing over time.The first option is not well supported by Sextus’ texts, where even a weak assertion is not allowed. The second option cannot explain the rationality of skeptical arguments. The third option reveals two levels of Sextan skepticism; however, the developing skeptic has to accept the self-refutation charge, and the mature skeptic takes flight from the charge without any rational answer. I claim that Sextus embraces the self-refutation charge. The mature skeptic’s speech acts are pragmatically inconsistent: their content cannot be asserted without contradiction. As a result, the charge of inconsistency is not answered.

Joshua Rasmussen From Necessary Truth to Necessary Existence
abstract | view |  rights & permissions
I introduce new details in an argument for necessarily existing propositions. The crux of the argument marks out a pathway to the conclusion that necessary truths cannot themselves be necessarily true unless they necessarily exist. I motivate the steps in the argument and then address several standard objections, including one that makes use of the distinction between ‘truth in’ and ‘truth at’. The purpose of the argument is to generate deeper insights into the nature of propositions and the logic of necessity. The argument also gives us a new reason to believe the traditional answer to the question of why there is anything: there is something because the alternative is impossible.

Marco Simionato Reconsidering Metaphysical Nihilism
abstract | view |  rights & permissions
In contemporary analytic philosophy metaphysical nihilism is the thesis according to which there might be nothing, i.e. a possible world with no concreteobjects in it, but that can contain (or must contain) abstract objects. After summarizing the set of premises from which analytic metaphysics deals with nothing, I propose a set of premises that could fit continental metaphysics. Then I propose a new set of premises for the question of nothing that derives from a synthesis of the two above mentioned sets. By means of this new set, I try to show that nothing as a possible world with no objects at all is not a self-contradictory entity and I propose an argument for proving that an empty possible world exists.
