As the finale of Haruki Murakami's "Youth Trilogy", "The Adventures of the Sheep" constructs a unique novel language system through metaphorical rhetoric, achieving a revolution in traditional literary propositions. The "sheep" as the core metaphor in the novel has multiple metaphors and rich interpretable space, reflecting Murakami's ethical thinking on postmodern Japanese society. There are various interpretations of the metaphorical meaning of "sheep" by domestic and foreign scholars, including Mongolian style will to power, modern Western European culture, modern Japan itself, Japanese concepts and ideas in the 1960s and 1970s, and the driving force behind Japan's survival and expansion. Murakami emphasizes the construction of metaphorical brain texts through the polysemy of "sheep", that is, the brain texts constructed by metaphorical subjects in the process of interpreting and applying metaphors, which becomes the key to understanding the ethical connotations of novels.

The construction of metaphorical and metaphorical brain texts

Deeply explored the concept of brain text and its role in metaphor construction. Brain text is the perception, cognition, understanding, and thinking of objective things that the brain stores in the form of memory. The concept of the brain is divided into signifier brain concept and signified brain concept, which respectively refer to things and concepts. In "The Adventures of the Sheep", "sheep" as a referential brain concept refers to specific things, while as a referential brain concept, it refers to other related or unrelated things. The metaphorical activity obtains metaphorical meaning through the combination of the referent brain concept and the referent brain concept, forming a metaphorical brain text. The interpreter deconstructs and reconstructs the metaphorical object in a specific ethical context, resulting in different metaphorical meanings. The choice of the interpreter is influenced by their brain text, and the interpretation results update the existing brain text, forming a new metaphorical brain text.

The construction of metaphorical and metaphorical brain texts

In depth exploration was conducted on the construction mechanism of metaphor in "The Adventures of the Sheep" and its role in literary creation and metaphorical activities. The interpreter deconstructs and reconstructs the metaphorical object in a specific ethical context through the concepts of signifier and signified brain, in order to obtain metaphorical meaning and form metaphorical brain text in the brain. The metaphor giver (writer) recombines and edits brain concepts and texts according to the ethical rules of literature through the process of perception, recognition, and understanding, generating literary brain texts. Haruki Murakami regards "memory" as brain text stored in the human brain, while "good metaphors" are a way to express brain text in his creations. Metaphors originate from the mental concepts or texts of the metaphoricalist, expressed through language or words. The various forms of expression in literary works, such as inner monologue, stream of consciousness, psychological description, etc., are closely related to the construction of literary brain texts. In "The Adventures of the Sheep", Murakami expresses his brain text through words to obtain the metaphor of "sheep", and its effectiveness depends on the effective transformation of the metaphorical brain text from the interpreter's brain text to the interpreter's brain text. The purpose of metaphorical activities is to convey the correct brain text to the interpreter, in order to guide their thoughts and behaviors. Murakami emphasized that literary creation should be used in reality and have an educational function, and metaphor as a rhetorical device should serve the educational function of literature. By setting metaphors, Murakami attempts to guide interpreters to construct brain texts with ethical significance, in order to achieve the practical guiding role of literature.

The Ethical Mechanism of Metaphorical Subject Constructing Brain Text

In depth exploration of the ethical mechanism of metaphorical subjects constructing brain texts in "The Adventures of the Sheep". The interpreter and the agent deconstruct and reconstruct the metaphorical object in a specific ethical context through the concepts of signifier and referent brain, generating metaphorical brain texts that guide thoughts and behaviors. Haruki Murakami reveals the ethical principles of constructing open and rational brain texts through the metaphor of "sheep" and the plot of "searching for sheep". Open brain texts allow interpreters to engage in diverse deconstruction and reconstruction, while closed brain texts limit the diversity of thinking. Murakami is concerned about the confrontation between open and closed systems in modern society, as demonstrated by the Aum Shinrikyo incident. He guides interpreters to construct open brain texts by blurring the characteristics of "sheep", promoting the formation of diverse thinking patterns to adapt to the ethical diversity of postmodern society.
