Wonderland and Looking Glass
If you look at the history of how the story came to be, Lewis Carroll was just telling the story to three little girls (one of which happened to be Alice Liddell the other two her sisters Edith and Lorina) whom lived very regimented lives. The father of the three girls taught Greek at Oxford University in England, and Carroll (Charles Dodgson) taught Mathematics. There was not much room for nonsense in the lives of these three little girls, so in telling stories to them Carroll created the nonsense for them. This way the children could be children. You must remember being a child once, think about some of the things Alice says to herself. She is a little girl forced to live in a grown-up world and be practical. These two stories (The Adventures in Wonderland and Through the Looking Glass) are just escapes for Alice and her two sisters. They are not really some drug induced psychotic episode. These stories have entertained children for generations and continue to do so. I am glad that Lewis Carroll created them. By the way, one last comment, the original illustrations by Sir John Tenniel are excellent.
