Hypotetické soudy, pravdivost a tvrditelnost / Hypothetical Judgements, Truth and AssertibilityPunčochář, Vít January 2016 (has links)
Vít Punčochář Dissertation: Hypothetical Judgements, Truth and Assertibility Abstract: The main topic of this thesis is the logic of indicative conditionals, i.e. sentences of the form If A then B. In classical logic, these sentences are analysed with the help of the so- called material implication. However, the analysis is problematic in many respects. Some chapters of the thesis are devoted to the explanation of the problems, which one necessarily faces when analysing conditionals with the apparatus of standard classical logic. The stress is laid upon the fact that here we are led to a paradoxical situation: some general principles of classical logic (e.g. the principle according to which one can infer If not-A then B from A or B) seem to be unquestionable, but they have very controversial consequences. In the thesis, attempts are presented to defend classical logic as well as to revise it. The approaches to the logical analysis of conditionals are classified into two basic kinds: the first one might be called ontic and the second one epistemic. The ontic approach defines all crucial semantic notions in terms of the concept of truth that is modelled in logic as a relation between sentences of a given language and states of affairs. In contrast, the epistemic approach is not based on the concept of truth...

Presupposition projection and entailment relationsGarcía Odón, Amaia 28 September 2012 (has links)
In this dissertation, I deal with the problem of presupposition projection. I mostly
focus on compound sentences composed of two clauses and conditional sentences in which the second clause carries a presupposition. The central claim is that the presupposition carried by the second clause projects by default, with the exception of cases in which the presupposition entails the first clause (or, in disjunctive sentences, the negation of the first clause). In the latter cases, the presupposition should not project, since it is logically stronger than the first clause (or its negation). Thus, in conjunctions, if the presupposition projected, the speaker’s assertion of the first clause would be uninformative. As for conditionals and disjunctions, if the presupposition projected, the speaker would show inconsistency in his/her beliefs by showing uncertainty about the truth value of the first clause (or its negation). I argue that, in conditionals, this uncertainty is conversationally implicated whereas, in disjunctions, it results from the context’s compatibility with the first disjunct. I maintain that, in cases where projection is blocked, the presupposition is conditionalized to the first clause (or its negation). I demonstrate that the conditionalization is motivated in a straightforward way by the pragmatic constraints on projection just described and that, contrary to what is defended by the so-called ‘satisfaction theory’, presupposition conditionalization is a phenomenon independent from local satisfaction. / En esta tesis, trato el problema de la proyección de presuposiciones. Me centro
mayoritariamente en oraciones compuestas de dos cláusulas y en oraciones
condicionales cuya segunda cláusula contiene una presuposición. El argumento central es que la presuposición contenida en la segunda cláusula proyecta por defecto, con la excepción de casos en los que la presuposición entraña la primera cláusula (o, en las oraciones disyuntivas, la negación de la primera cláusula). En estos últimos casos, la presuposición no debería proyectar, puesto que es lógicamente más fuerte que la primera cláusula (o su negación). Por tanto, en las oraciones conjuntivas, si la presuposición proyectase, la aseveración de la primera cláusula por parte del hablante no sería informativa. En cuanto a las oraciones condicionales y disyuntivas, si la presuposición projectase, el hablante mostraría inconsistencia en sus creencias al mostrar incertidumbre acerca del valor de verdad de la primera cláusula (o su negación). Sostengo que, en oraciones condicionales, esta incertidumbre es implicada conversacionalmente mientras que, en las oraciones disyuntivas, resulta de la compatibilidad contextual de la primera cláusula. Mantengo que, en casos en los que la proyección es bloqueada, la presuposición es condicionalizada a la primera cláusula (o su negación). Demuestro que la condicionalización es motivada de manera directa por las restricciones de tipo pragmático descritas arriba y que, contrariamente a la idea defendida por la así llamada ‘teoría de la satisfacción’, la condicionalización de la presuposición es un fenómeno independiente de la satisfacción local de la misma.

Conditional Constructions in Damascus Arabic : Form and meaningJalonen, Jenni January 2017 (has links)
This paper treats the relationship between form and meaning in conditional constructions in Damascus Arabic (DA). More specifically, it treats two, main formal categories of DA conditional constructions: the conditional marker and the verb morphology and, further, how these are related to various degrees of conditional hypotheticality. Apart from the introductory section (Introduction, Aim, Method and Classification of DA), the paper consists of three larger sections: Section 2 gives a basic, theoretical background of crosslinguistic conditional constructions as well as what previous scholars have said about the crosslinguistic relationship between conditional form and meaning. It is found that many of these scholars tend to describe form, but neglect deeper discussions of meaning. This section also provides a general background of the verbal system in DA and the primary TAM (Tense-Aspect-Mood) categories of DA verb forms. The main analysis of this thesis is found in section 3. In this section, I first suggest a method of analysis called ‘the hypotheticality continuum’ which is then employed in the following sub-sections, following Comrie (1986). Thereafter, attention is first paid to DA protasis markers and how the choice of marker is related to hypotheticality. Thirdly, I deal with verb morphology and how the choice of verb form together with a given protasis marker contributes to creating even more fine-grained distinctions of hypotheticality in DA conditional constructions. Lastly, a presentation of results and final discussion in section 4 conclude the paper.

Form-function Mappings in the Acquisition of If-conditionals: A Corpus-based Study / 以語料庫為本對英語條件句形式功能對應習得之研究柯羽珊, Ke,Yu-shan Unknown Date (has links)
本研究旨在探討以中文為母語之人士如何學習英語條件句，及其在習得時所遭遇之困難及相關原因。本文除對英語條件句之分類方式做詳盡介紹外，並嘗試以形式功能對應之理論架構，研究其習得之順序，並利用『錯誤分析』區分出條件句之動詞各類錯誤的誤用形式及原因。本研究語料來源為包含一百萬字，以電腦輔助建立錯誤標記之『中國學習者英語語料庫』。
研究結果發現，外語學習者之習得順序為一形式功能對應之過程，具較多形式或功能內涵者愈晚且愈難習得，符合功能認知模式的預測。 中文學習者的錯誤特徵為添加及省略，原因為過度矯正(hypercorrection)及過度類化(overgeneralization)。學習者最大的困難來自對條件句動詞變化規則不熟悉、形式及功能的複雜性、以及對應失敗的結果。本論文建議未來研究方向可深入探討時間指涉與假設程度對條件句使用之影響。 / Issues of conditionals have been highlighted for a long time, but the focus was seldom fixed on acquisition, particularly for L2. The determinate features of tense, mood and modality are interwoven in the conditional construction, thus resulting in an insurmountable obstacle for L2 learners. However, the factors impede acquisition have never been satisfactorily treated. Therefore, this paper attempts to explore the L2 developmental sequence, and to probe the error characteristics of acquiring if-conditionals.
Disengaging the expression of conditionality into two dimensions: temporality and hypotheticality, we identified the features of syntactic forms and semantic functions of different conditional types, and created a new scheme to account for their mapping, on which the difficulty levels of acquisition were inferred. In contrast to the previous studies on the grounds of markedness theories, this research described the acquisition of conditionals in a Functional-Cognitive Model. Furthermore, the factors of difficulties were examined via an error analysis.
The targets are Chinese English learners, who were well-known to face great problems in expressing conditionals. The data was searched from CLEC (Chinese Learner English Corpus), a big-scale corpus consisting of roughly 1,000,000 words with error tags.
The investigation on the acquisition sequence and error patterns shows: (1) the acquisition order parallels to the prediction on the form-function mapping underpinnings: those with heavy content load and complex lexical shapes are acquired later (2) the two prominent misuses of the Chinese learners are addition and omission, resulted from hypercorrection and oversimplification. It was concluded that their difficulties could be ascribed to unfamiliarity of rules, complexities of forms and functions, and their mapping failure. Hence, this present work serves to provide some explanatory accounts, in a hope to unveil the mystery of the arduousness of acquiring conditionals, contribute to the tightening of acquisition theorizing and shed new insights into pedagogical growth.
