In the past decades, quotation theories have developed roughly along three lines—quotation types, meaning effects, and theoretical orientations toward the semantics/pragmatics distinction. Currently, whether the quoted expression is truth-conditionally relevant to the quotational sentence, and if there is a truth-conditional impact, whether it is generated via semantic or pragmatic processes, have become the central concerns of quotation studies.In this book, quotation is clearly defined for the first time as a constituent embedded within yet distinctive from the quotational sentence. Also, as the first monograph to address the semantics/pragmatics boundary dispute over quotation, it argues that the semantic content of quotation amounts to its contribution to the intuitive truth-conditional content of the quotational utterance via two modes of presentation, which are incarnated in the functioning of quotation marks and manifested as use and mention. The use/mention-based analysis in this book can shed light on the semantic theorizing of other metalinguistic phenomena, while the semantics/pragmatics perspective will provide methodological implications for other relevant studies.The new conception of quotation and thought-provoking analysis on use/mention, truth-conditional pragmatics, and the semantics/pragmatics boundary in this book will appeal to scholars and students in philosophy of language and linguistics. It will also serve as a clear guide to the current state of quotation studies and how to formulate a semantic theory of quotation.
