In 1871, Carroll published the second part of the Alice´s adventures: Through the Looking-Glass. This second book has to be considered as a continuation of Alice in Wonderland. Alice goes across the looking-glass and this means that Alice goes across her childhood .

World into the looking-glass is like Alice´s world but at the same time this world is completely different because it is a kind of inverted reality. We have several examples: § Alice has to go backwards to find the place where the Black Queen is; ¨ the Black Knight put the left shoe on his right foot; © temporarily, the White Queen lives other way round ; ª first, Alice serves out the cake and then she cuts it...

In Through the Looking-Glass we find characters named Humpty Dumpty or Tweedledum and Tweedledee. They are known by english children and have become the kings of nonsense or absurd. "Nonsense" represents an scape from common sense. But, at the same time the nonsense is based on sense, thus sense doesn´t exist without nonsense; as a result of this we come to the conclusion that even nonsense has to make sense. Carroll was a reasonable man that wrote illogical stories; we think that only a logical man could become illogical, and Alice realized that adults world was full of crazies.

According to Carroll, Language is the onlly game that adults retain from their childhoods, thus when an adult plays with words, he/she returns to childhood.
