Is Alice in Wonderland a fantasy or a philosophy?

It is both.

Alice's Adventures in Wonderland was originally created to entertain three little girls on a lazy boat ride on a warm day. Naturally, tales of a relatable heroine on an adventure through a strange and wonderful land did the trick nicely.

When the author, Lewis Carroll (real name Charles Dodgson), went to pen the tale as a gift to one of those little girls, he added satire and jeering mockery beneath the layers of whimsical fairy tales.

Before the book was printed, it was expanded on even further to include famous scenes such as the mad tea party and famous characters such as the Cheshire Cat, scenes and characters which were used for further childish entertainment as well as logical and illogical conundrums.
