In "The Legend of Luke" by Brian Jacques, the character expresses a strong sense of self-reliance and independence. The quote highlights a refusal to accept help or guidance from others regarding his identity. The use of phrases like "jolly well ask m'self" and "pish tush" conveys a whimsical yet determined attitude, indicating that he takes pride in knowing himself without the need for external validation.

This declaration shows a deeper theme of self-discovery within the story. The character's playful dismissal of the idea of others defining his name reflects a broader message about personal agency and the importance of understanding oneself. Jacques’ writing encapsulates this spirit through humor and a touch of bravado, inviting readers to appreciate the journey of self-identity.
