The story that tells us the truth about the human nature, the humans have lost their humanity.Franz Kafka uses many symbols in the novella Metamorphosis.
Kafka chose the German word for vermin –Ungeziefer – which means an animal with a disgusting nature.
The German word was also used in World War II, the Nazis used to describe the Jews by this name.
This supports the suggestion that Gregor Samsa is a stranger in a strange land and is quite debilitated by his insect existence which forces him to symbolically hid from society, even from those that love him as a son and a brother.
At this point in the Metamorphosis, it is abundantly clear that Gregor Samsa's life has been utterly transformed, much like his physical body, and that he considers himself to be a vermin, akin to a rodent living in a trash heap. Another symbolic description occurs when Gregor's mother and sister begin to remove furniture from Gregor's bedroom.
He uses this technique to make the reader try and figure out what was going on in his head. Now that his sister is grown up they can force her into marrying a rich man.
He brought out in this story many things about his life, including his father/family, love life, and his future. Then they would be well off for a long time to come. Once she is married, she too will then become a pawn, a victim of her parents control.
What is the importance of symbolism in Metamorphosis by Franz Kafka?
The ones that you love the most are usually the ones that hurt you the most.
In the very first paragraph of the Metamorphosis, Kafka relates that Gregor Samsa, the main protagonist in the tale, "awoke one morning" and "found himself transformed in his bed into a gigantic insect" with an "armoured-plated back. Biographically, Kafka did exactly this when, as a result of being denigrated by his father, "Kafka refused to take up his father's business, instead choosing his own path" (Batson, "Kafka/Samsa," Internet).
Of course, "magic realism" is most closely linked to the so-called "Black Arts" and the practice of witchcraft, both of which rely very heavily on symbols to express thoughts and ideas.
