The White Rabbit represents time and mortality in Alice's adventures in Wonderland. The White Rabbit's constant obsession with time and his repeated catchphrase, "I'm late! I'm late! For a very important date!", symbolizes the relentless nature of time and its effect on life and destiny.
The character embodies the ephemeral nature of existence. Alice also remarks several times throughout the journey about how quickly the time appears to be flying for her which parallels The White Rabbit's frantic quest in pursuit of time while she embarks on an odyssey of discovering a new reality.
