比喻是一种“借彼喻比”的修辞法。所谓“彼”与“比”,是指两个独立的物象,但却存在着某项或数项的共通点,于是透过心理学所谓的类化作用,进行着借代联想。比喻一般皆以易知说明难知,根据事物之间的相似点,以具体形容抽象,而达到“状难写之景如在目前”的妙境。巧妙的运用比喻 Metaphor is a rhetorical method of “borrowing one’s metaphorical ratio.” The so-called “Peter” and “Than” refer to two independent images, but there are some commonalities between them.
