In "Cloud Atlas" by David Mitchell, Luisa reflects on the relationship between bluster and duplicity. She observes that when people are overly boastful or aggressive in their proclamations, it often masks hidden motives or dishonesty. This insight reveals a deeper understanding of human behavior, suggesting that confidence is sometimes a facade for less admirable intentions.

Luisa's contemplations highlight a theme prevalent throughout the novel: the complexity of truth in social interactions. The juxtaposition of outward bravado against underlying deceit serves as a reminder to critically assess the words and actions of others, understanding that appearances can be misleading.
