Poetry can be criticized only through poetry. A critique which itself is not a work of art, either in content as representation of the necessary impression in the process of creation, or through its beautiful form and in its liberal tone in the spirit of the old Roman satire, has no right of citizenship in the realm of art.
"Dialogue on Poetry and Literary Aphorisms" by Karl Wilhelm Friedrich Schlegel, translated by Ernst Behler and Roman Struc, Pennsylvania University Press, 1968.
