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)

By observing the mediating role of Pomarańczowa Alternatywa [Orange Alternative], the Polish artistic-activist formation of the 80s and 90s, this paper aims to determine the properties, values and ideals that make a piece of art a public act that can engage people from different social groups in play, and can allow them to reveal their self-determining agency in light of social change. Within the system of varying degrees of social permission, art should allow for the transition from the realm of (...) the “unofficial” to the realm of the “forbidden,” and should facilitate a transformation from the realm of thought to the realm of action. Art introduces an element of play into the sphere of collective behavior, and is a bridge over dichotomous social and political forces. (shrink)

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.

Timothy Williamson has argued that, unless the speech act of assertion were supposed to be governed by his so-called Knowledge Rule, one could not explain why sentences of the form "A and I do not know that A" are unassertable. This paper advances three objections against that argument, of which the first two aim to show that, even assuming that Williamson's explanandum has been properly circumscribed, his explanation would not be correct, and the third aims to show that his explanandum (...) has not been properly circumscribed.

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)

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.

As we know, the Fifteenth World Congress of Philosophy has as its general theme problems of science, technology, and man. Any aspect of this all-encompassing theme produces many questions. Our task is to single out certain important aspects in it.

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

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.

Is uncertainty, often brought about by loss, collapse, interruption, or disturbance in life, an entirely negative state that must be resolved as soon and as fully as possible by resettlement? Or, can we view uncertainty and loss as affective states that might open up new possibilities for friendships, solidarities, collectivities, and hope? As a response to Carla J. Maier’s ‘The Table and the Dancer’ this essay attends to affective and emotional registers of migration. It attempts to rethink the senses of (...) loss, uprootedness, and uncertainty as possible sources for affinities and hope, with a particular focus on the new migration from Turkey. (shrink)

The analysis of mixed quotation proposed in Cappelen & Lepore (1997), purportedly as a development of Davidson's accounts of direct and of indirect quotation, is critically examined. It is argued that the analysis fails to specify either necessary or sufficient conditions on mixed quotation, and that the way it has been defended by its proponents makes its alleged Davidsonian parentage questionable.

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.

This paper argues that the obvious validity of certain inferences involving indirect speech reports as premises and truth or falsity ascriptions as conclusions is incompatible with Davidson's so-called "paratactic" analysis of the logical form of indirect discourse. Besides disqualifying that analysis, this problem is also claimed to indicate that the analysis is doubly in tension with Davidson's metasemantic views. Specifically, it can be reconciled neither with one of Davidson's key assumptions regarding the adequacy of the kind of semantic theory he (...) recommends nor with one of his key assumptions regarding the inadequacy of a kind of semantic theory he rejects.

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.
