Here are a couple of examples:
* "Curiouser and curiouser!" This line, often repeated by Alice, embodies the feeling of being in a strange and unfamiliar place, where the rules don't apply. This could be seen as a metaphor for being "outside" of one's usual reality.
* "Why, sometimes I've believed as many as six impossible things before breakfast." This quote highlights the absurdity of Wonderland and the fluid nature of truth. It suggests that reality is malleable and the line between "inside" and "outside" of logic can be blurred.
* "I shall elucidate." This is said by the Duchess, implying a sense of understanding and clarity that Alice may not possess. This could be seen as a representation of being "inside" a knowledge that Alice, being "outside," doesn't yet grasp.
These are just a few examples, and the interpretation of the quote's relation to the theme of "inside or outside" is ultimately subjective.
