In modem literature, the condition of mankind is depicted using elements such as abnormality and folly. Realism, which tries to depict reality, is the literature of modem era in contemporary times. Realism is not only a style among other literary schools, but it is also the rudiment of literature, for other literary styles, particulary in recent centuries, have originated from
