The sign through which we express the thought I call the propositional sign. And the proposition is the propositional sign in its projective relation to the world.

我将那些用来表达思想的符号称为命题符号。一个命题就是一个处在对世界的投影关系中的命题符号。

According to relevance theory, metaphor is but a kind of loose talk whose propositional form resembles that of the speaker's thought.

根据关联理论，隐喻是随意言谈的一种，它的命题形式与说话人思想的命题形式之间存在着相似关系。
