✦ Synopsis

Our main interest in this paper is to translate from "natural language" into "'system theoretical language". This is of course important since a statement in system theory can be analyzed mathematically or computationally. We assume that, in order to obtain a good translation, "system theoretical language" should have great power of expression. Thus we first propose a new frame of system theory, which includes the concepts of"measurement" as well as "state equation". And we show that a certain statement in usual conversation, i.e., fuzzy modus ponens with the word "very", can be translated into a statement in the new frame of system theory. Though our result is merely one example of the translation from "natural language" into "system theoretical language", we believe that our method is fairly general.
