Throughout the narration of his character's experiences, Kafka holds in suspension European, urban, and early twentieth-century masculine attitudes towards woman and transforms these attitudes by presenting Grete and mother Samsa in the roles of Gregor's caretakers and feeders and then revealing their rebellion against these roles.
I am not sure what does "holds in suspension" mean? Is the meaning of the sentence that Kafka's attitude towards women does not differ from the standards of his time?
