Mutually exclusive meanings
In his essay, Paul de Man talks about intrinsic and extrinsic criticism in terms of inside and outside. Intrinsic criticism is focused on form as the outside and content as the inside (). On the other hand, extrinsic criticism is focused on content as the outside form as the inside (). His means that intrinsic criticism is about analyzing the language itself without emphasis on the meaning while the extrinsic criticism is exactly the opposite. De man says that American literature has to return to intrinsic criticism, but moreover, he states that language must be seen from a different perspective: language can be syntagmatic and pragmatic at the same time. This is a paradoxical statement that seems incoherent at first glance but proofs to be a very interesting theory.
The syntagmatic and pragmatic characteristics of language are described as grammar and rhetoric by Paul de Man. De Man says this when talking about semiology. He says “one of the most striking characteristics of literary semiology is the use of grammatical (especially syntactical) structures conjointly with rhetorical structures (de Man 1368). That is to say that the syntagmatic structures of language are what is described as grammar by semiology; the pragmatic characteristics of language is what semiology describes as rhetoric. It is important to highlight that rhetoric I define as “the study of tropes and figures” (de Man 1368).
According to de Man, grammar refers to the structure of the language itself. Additionally, grammar also refers to the syntactical relationship of signs and logic. Also it has to convey a meaning both “locutionary” and “illocutionary”. The locutionary part of grammar is the sentence while illocutionary is the tone of the sentence” “ordering, questioning, denying…” The illocutionary part of grammar seems to be a direct transition to rhetoric (de Man 1369). Rhetoric refers to how one sentence can have more than one meaning and each of these meanings can be “mutually exclusive” (de Man 1370); this is the work of metonymies and metaphors. More importantly, rhetoric allows us to understand which meaning we should choose.
Grammar and rhetoric are very complex ideals to understand. Let’s look at the following example: In a conversation between two individuals, one of them says, “What did you just said!” Grammatically, this could mean two things: “I am very surprised by what you said” or “what you just said annoyed me.” However the illocutionary tools of grammar cannot help us decide which content is used in the conversation. Only through the means of rhetoric we can understand which definition is the correct. Yet, it does not mean that a text is rhetorical when one meaning is right and the other is wrong in a particular situation. As de Man states “The grammatical model of the question becomes rhetorical …when it is impossible to decide by grammatical or other linguistic devices which of the two meaning (that can be entirely incompatible) prevails” (de Man 1371). That is to say, that the rhetorical component is what help us find the meaning that prevails through other means that are not grammatically. It is something that is beyond the sentence content may include a whole paragraph or even the whole book.
