The quote from "Master and Commander" by Patrick O'Brian suggests that the Navy communicates through symbolic language, allowing for varying interpretations of its messages. This highlights the idea that communication can be layered and complex, where the actual meaning may depend on the perspective and understanding of the listener. The use of symbols can add depth to interactions, especially in a formal or structured environment like the Navy.

Furthermore, this statement reflects the broader theme of interpretation in human communication. Just as naval terms and symbols can convey different meanings, so can words in general. The listener's background, experience, and intent can shape their understanding, making communication both an art and a science. O'Brian's work often explores such nuances in relationships and leadership, emphasizing the richness of language and meaning in societal interactions.
