Using Finsler brane solutions [see details and methods in: S. Vacaru, Class. Quant. Grav. 28:215001, 2011], we show that neutrinos may surpass the speed of light in vacuum which can be explained by trapping effects from gravity theories on eight dimensional (co) tangent bundles on Lorentzian manifolds to spacetimes in general and special relativity. In nonholonomic variables, the bulk gravity is described by Finsler modifications depending on velocity/momentum coordinates. Possible super-luminal phenomena are determined by the width of locally anisotropic brane (...) (spacetime) and induced by generating functions and integration functions and constants in coefficients of metrics and nonlinear connections. We conclude that Finsler brane gravity trapping mechanism may explain neutrino super-luminal effects and almost preserve the paradigm of Einstein relativity as the standard one for particle physics and gravity.

Three values for non-transferable utility games -- the Harsanyi NTU-value, the Shapley NTU-value, and the Maschler--Owen consistent NTU-value -- are compared in a simple example.

We consider a new fragment of first-order logic with two variables. This logic is defined over interval structures. It constitutes unary predicates, a binary predicate and a function symbol. Considering such a fragment of first-order logic is motivated by defining a general framework for event-based interval temporal logics. In this paper, we present a sound, complete and terminating decision procedure for this logic. We show that the logic is decidable, and provide a NEXPTIME complexity bound for satisfiability. This result shows (...) that even a simple decidable fragment of first-order logic has NEXPTIME complexity. (shrink)

The main objective of this essay is to offer an answer to the following question: Is there a scientific ground for the theory of the historical opposition between liberalism and the nation? In order to answer this question, this essay is organised in three parts. The first part identifies the position of the nation within the classical liberal discourse; the second identifies the crucial moment of the 1950’s as the precise period in which a major change in the relation between (...) liberalism and the nation took place; the third one identifies the moment of the nation’s restoration within the contemporary liberal discourse. The main conclusion of this essay is that, except for a brief though noteworthy period (which explains the actual apparent consensus concerning the opposition between the liberal and the national theories), the nation was a fundamental component of the liberal discourse and of the liberal political practices rather than a result of an opposing political vision.

Infants’ ability to monitor “sensorimotor contingencies,” i.e., the sensory effects of their own actions, is an important mechanism underlying learning. One method that has been used to investigate this is the “mobile paradigm,” in which a mobile above an infant’s crib is activated by motion of one of the infant’s limbs. Although successfully used in numerous experiments performed in infants’ homes to investigate memory and other types of learning, the paradigm seems less robust for demonstrating sensitivity to sensorimotor contingencies when (...) used in the laboratory. One purpose of the present work was to show that certain changes to the mobile paradigm would make it easier for infants to show their sensitivity to the contingency in the lab. In particular, we used proximal stimulation on infants’ wrists instead of the usual mobile, and our stimulation was coincident with the limbs that caused it. Our stimulation was either on or off, i.e., not modulated by the amount the infant moved. Finally, we used a “shaping” procedure to help the infant discover the contingency. In addition to these changes in the paradigm, by analyzing infants’ limb activity at 10-s resolution instead of the usual 1-min resolution, we were able to show that infants’ sensitivity to the contingency became apparent already within the first minute of establishment of the contingency. Finally, we showed how two alternate measures of sensitivity to contingency based on probability of repeated movements and on “stop and go” motion strategies may be of interest for future work.

This paper argues that a certain type of self-referential sentence falsifies the widespread assumption that a declarative sentence's meaning is identical to its truth condition. It then argues that this problem cannot be assimilated to certain other problems that the assumption in question is independently known to face.

Foundations of Speech Act Theoryoffers a timely, thorough and, above all, compelling examination of the complexities of illocutionary acts, performatives, and their phenomenological basis. Savas Tsohatzidis has collected an impressive range of international scholars on the subject. Clearly demonstrating the relevance of speech act theory to semantic theory, the collection further interrogates the inability of pragmatic theories of illocution to properly locate such speech acts within the logic of phenomenology and intersubjectivity.

This paper argues that Michael Dummett's proposed distinction between a declarative sentence's "assertoric content" and "ingredient sense" is not in fact supported by what Dummett presents as paradigmatic evidence in its support.

In Part I of this paper, an abstract analogue of the minimization problem for Boolean functions and of the notion of prime implicant is defined, so that this general problem can be solved in the same steps as in the classical case: 1) determination of the prime implicants; 2) determination of all the solutions made up of prime implicants. In Part II it is shown that the classical minimization problem, as well as certain set-theoretical and graphtheoretical problems are particular cases (...) of the general problem defined in Part I.

We study ranges of algebraic functions in lattices and in algebras, such as Łukasiewicz-Moisil algebras which are obtained by extending standard lattice signatures with unary operations.We characterize algebraic functions in such lattices having intervals as their ranges and we show that in Artinian or Noetherian lattices the requirement that every algebraic function has an interval as its range implies the distributivity of the lattice.

The set (X, J) of fuzzy subsetsf:XJ of a setX can be equipped with a structure of -valued ukasiewicz-Moisil algebra, where is the order type of the totally ordered setJ. Conversely, every ukasiewicz-Moisil algebra — and in particular every Post algebra — is isomorphic to a subalgebra of an algebra of the form (X, J), whereJ has an order type . The first result of this paper is a characterization of those -valued ukasiewicz-Moisil algebras which are isomorphic to an algebra (...) of the form (X, J) (Theorem 1). Then we prove that (X, J) is a Post algebra if and only if the setJ is dually well-ordered (Theorem 2) and we give a characterization of those -valued Post algebras with are isomorphic to an algebra of the form (X, J) (Theorem 3 and Proposition 2).

This book collects twenty-five of the author's essays, each of which addresses a descriptive or a foundational issue that arises at the interface between linguistic semantics and pragmatics, on the one hand, and the philosophy of language, on the other. Arranged into three interconnected parts (I. Matters of Meaning and Truth; II. Matters of Meaning and Force; III. Knowledge Matters), the essays suggest that some key topics in the above-mentioned fields have often been approached in ways that considerably underestimate their (...) empirical or conceptual complexity, and attempt to delineate perspectives from which, and conditions under which, an improved understanding of those topics could be sought.

In this volume, Savas L. Tsohatzidis brings together a team of leading experts to provide up-to-date perspectives on the work of J. L. Austin, a major figure in twentieth-century philosophy and an important contributor to theories of language, truth, perception, and knowledge. Focusing on aspects of Austin's writings in these four areas, the volume's ten original essays critically examine central elements of his philosophy, exploring their interrelationships, their historical context, their reception, and their implications for key issues of contemporary philosophical (...) research. The volume deepens our understanding of Austin's philosophy while illustrating its continuing significance, and will appeal to students and scholars of modern philosophy, particularly to those interested in the philosophy of language and epistemology.

This is a volume of original essays on key aspects of John Searle's philosophy of language. It examines Searle's work in relation to current issues of central significance, including internalism versus externalism about mental and linguistic content, truth-conditional versus non-truth-conditional conceptions of content, the relative priorities of thought and language in the explanation of intentionality, the status of the distinction between force and sense in the theory of meaning, the issue of meaning scepticism in relation to rule-following, and the proper (...) characterization of ‘what is said’ in relation to the semantics/pragmatics distinction. Written by a distinguished team of contemporary philosophers, and prefaced by an illuminating essay by Searle, the volume aims to contribute to a deeper understanding of Searle's work in philosophy of language, and to suggest innovative approaches to fundamental questions in that area.

A problem is raised for the introduction rules proposed in Benjamin Schnieder’s ‘A logic for “because”’, arising in connection with (a) inferences that the rules should not, but do, validate and (b) inferences that the rules should, but do not, validate.

This paper examines, and rejects, a recent argument to the effect that knowledge is not truth-entailing, i.e. that “know” is not factive.

The aim of this study is to investigate students’ conceptions about proof in mathematics and mathematics teaching. A five‐point Likert‐type questionnaire was administered in order to gather data. The sample of the study included 33 first‐year secondary school mathematics students . The data collected were analysed and interpreted using the methods of qualitative and quantitative analysis. The results have revealed that the students think that mathematical proof has an important place in mathematics and mathematics education. The students’ studying methods for (...) exams based on imitative reasoning which can be described as a type of reasoning built on copying proof, for example, by looking at a textbook or course notes proof or through remembering a proof algorithm. Moreover, they addressed to the differences between mathematics taught in high school and university as the main cause of their difficulties in proof and proving. (shrink)

Starting from the four principles of Pólya's problem-solving method, by analogy, in this paper we propose a new method of philosophical counseling. Thus, the objectives of this study are as follows: the review of several methods of philosophical counseling; justifying the need for a new method, which we called the IPAA method; developing the four principles – the principle of identification (I), the principle of planification (P), the principle of application (A) and the principle of assumption (A). In order to (...) achieve these, we took into account the fact that the nature of the philosophical problems faced by the clients of the philosophical counselors, whether they are existential, moral or metaphysical, can be solved on their own. Therefore, we argued that if in the first instance, clients really need the input of the philosophical counselors, as long as the latter uses the IPAA method – a problem-solving method – they can offer clients the opportunity to self-counsel. The novelty of the IPAA method consists in the fact that it offers the client, assisted and guided at the beginning by the counselor, the possibility to carry out the act of counseling outside the office, being empowered to apply the four methodical principles mentioned above. The present study is relevant in that the new IPAA method, a method focused on solving everyday problems, is a useful method for both philosophical counselors, as its application in the office helps them to train the clients in researching, understanding and assuming their own lives, as well as for the clients, because if they are assisted in the first instance by the counselor's expertise, they can independently clarify and solve their daily difficulties.

This collection should be welcomed by anyone working on the subtle interplay between theories of perception, internalism and externalism about mental and linguistic content, and the linguistic expression of mental states. Many of these connections have been put into focus by John Searle, and his views are here subjected to careful scrutiny from a variety of directions. The contributions do not sum to a general discussion of Searle's contributions to the philosophy of mind and language. There is little or nothing (...) here on, for example, the Chinese rooms and Strong AI, or on his more recent work on social construction and rationality. Such absences are an inevitable consequence of the sheer number of influential theses Searle has advanced over the decades. Instead, the locus of discussion is the systematic perspective most clearly set out in his work, a fact that lends integrity to the volume.The book is divided into two main parts, with inevitable links across the divide. The first is concerned with the intentionality of mental states, and the second with the intentionality of linguistic acts. The first kind of intentionality is, according to Searle, intrinsic, while the second is inherited from the first, with linguistic conventions affording the derivation. The two kinds of intentionality parallel one another …. (shrink)
