Stifter is one of the representative authors of Biedermeier Genre of German Literature in early 19 th century, generally classified as a realistic writer. However, "Turmalin," a novel containing his reflection on poetics, implies the language crisis of modernity and the deconstructive features of postmodern novels. The description of housing and household goods metaphorizes the looseness and decline of the patriarchal order. The prominence of the object itself reveals man’s fascination with things and the reversed relationship between people and things. The relation between man and language is alike. The artistic activities of the characters inside the text correspond to the artistic form of the novel itself, which makes the novel show the potential of self-deconstruction. Facing the turbulence, development and change of society, Stifter’s poetic ideal expressed clearly his pursuit of the gentle law and eternal order, but his works told the limitations of human cognition, the crisis hidden in order, and the trend of eternal disintegration.
