In "Alice in Wonderland" by Lewis Carroll, the quote highlights the importance of visual elements and dialogue in making a book engaging and meaningful. Without pictures or conversations, a book may lack the vitality and interest needed to captivate readers, especially young ones who connect with illustrations and lively exchanges. Such features help bring characters to life and enhance the storytelling experience.

The quote also suggests that illustrations and conversations are essential components that make a story more immersive and memorable. They add depth, humor, and charm, transforming simple words into a captivating journey. Without these elements, a book risks becoming dull and less impactful for its audience.
