The quote from "The BFG" by Roald Dahl highlights the theme of skepticism and the limitations of human perception. The character mentions that just because we haven't personally encountered something—like giants or snozzcumbers—we tend to dismiss their existence. This illustrates how people often rely on personal experience to validate reality, rather than accepting the possibility of things beyond their understanding.

This perspective encourages readers to keep an open mind about the unknown. It challenges the notion that reality is solely defined by tangible experiences and suggests that imagination and belief play crucial roles in discovering new possibilities. Dahl's whimsical narrative invites readers to entertain the idea that there is much more to the world than what meets the eye.
