Alice - seven year old girl who dreamed of adventures in underground Wonderland and Through the Looking Glass, where she met with a variety of fabulous and fantastic characters living in their particular logic and reasonable at all times perplexing young viktorianku. As the embodiment of all the children of Victorian virtues: politeness, friendliness, modesty, moderation, seriousness, self-esteem, while A. saves himself the spontaneity and emotional openness that are so valued in their little girlfriends timid, stuttering Oxford professor of mathematics Dodgson. The world of nonsense, which falls A., often irritates her, strange characters she meets, as a rule, picky, irritable and touchy, but it lacks the common sense to come to terms with the situation, be able to turn the conversation to another topic, marveling at the strangeness of opening before her world, at the same time to take him as he is. After all, despite its seeming strangeness and inexplicable, in the world of Wonderland and the Looking-Glass reigns its impeccable logic.
It is a world where everything is taken literally, where the metaphor loses its figurative meaning, where between homophones no semantic boundaries, resulting in such a pun not even there, where the paradox is the result of a perfect logical construction. At the same funny parody poems, abundantly found in the text, according to the original in familiar logical and grammatical connections are suddenly very different, and sometimes just meaningless words. (For example, instead of the well-known lines: "You are flashing, star night / Where are you, who you are, I do not know!" - We read: "You flashes, owl me, / I do not know what's wrong.") Mathematics and logic K. was very close look at the reality of children, not burdened by cultural tradition, creating a complex system of ellipses, omissions, conditional constructs, historically acquired values, conclusions long ago lost touch with their parcels. The ambiguity of the living language, the fact that the statements of various judgments of many must be kept in the "mind", relating to the whole system of cultural conventions and unwritten rules, not once, as we have seen from numerous records of children's conversations "two to five" includes in the child's mind. A., located halfway between the children of the state of primordial chaos, held a bizarre logic to cultural orderly cosmos adults is due to open, and the first (after all, Wonderland and Through the Looking Glass - it's still just a dream of her), and the second (their judgments about an event she says from the point of view of the generally accepted norms of his time).
