按照罗蒂“信念之网”的理论模型,隐喻是在知觉和推理之外第三种改变信念的方法。隐喻通过改变词语的用法,使得语言游戏规则发生改变,改变了概念框架,从而重新编织了人类的信念之网。隐喻的产生是偶然的,体现了人类活动无穷无尽的创造性和自发性。隐喻作为改变语言和逻辑可能性空间的手段,普遍存在于包括自然科学在内的一切领域。 According to the theoretical model of Rorty “Faith Network ”, metaphor is the third way to change belief beyond perception and inference. Metaphor, by changing the usage of words, changes the rules of the language game, changing the conceptual framework and thus reweaving the web of human beliefs. The metaphor is generated by chance, reflecting the endless creativity and spontaneity of human activity. Metaphor as a means to change the space of linguistic and logical possibilities is ubiquitous in all fields, including the natural sciences.
