Russian Formalism focuses on the"materiality"of language,starting with the"procedure"of artistic creation and the sound shape of poetic language,and eventually developing"material"criticism;they attempt to break through the"Prison-House of Language",expanding the speech of poetic language from the linguistic to the cultural field and linking artistic forms to human feelings and actions,ultimately giving them the potential to change reality.Therefore,Russian formalism is not simply a"form-only"theory,but has realistic meanings and cultural connotations.
