战争合法化的话语策略——美国总统阿富汗战争演讲的批评话语分析

Discursive Strategies of War Legitimation: A Critical Discourse Analysis of American Presidential Speeches on the Afghanistan War

本研究从批评话语分析的角度出发,以van Leeuwen的"合法化"话语策略为分析框架,对50篇美国总统阿富汗战争演讲中合法化话语策略的分布、实现方式和运作机制进行了分析。研究揭示了这些演讲如何运用合法化话语策略建构正义的"我方"、非正义的"他方",将本质残酷、颇具争议的战争建构为目的高尚、动机正当、广受支持的合法行为。

Adopting the perspective of Critical Discourse Analysis and following the analytical framework of discursive strategies of legitimation developed by van Leeuwen,this study examines the distribution,realization and working mechanism of discursive strategies of legitimation in 50pieces of American presidential speeches on the Afghanistan war. The study reveals howthe discursive strategies of legitimation construct a righteous 'us'and an evil 'the other',in an effort to construct a cruel and controversial war as a legitimate action with noble purposes,reasonable motivation and wide support.
