Read the following passage from Kafka's The Metamorphosis.
Because of his injuries, Gregor had lost much of his
mobility – probably permanently. He had been reduced to
the condition of an ancient invalid and it took him long,
long minutes to crawl across his room - crawling over the
ceiling was out of the question – but this deterioration in
his condition was fully in his opinion) made up for by the
door to the living room being left open every evening.
How does this passage help develop Kafka's theme of mind versus body?
