What status can be attributed to morphology today? Is it a doctrine or a method? This AZP supplement explores the various uses of morphology through exemplary studies. The underlying hypothesis is that morphology serves as a paradigm in the sciences. The contributions show that even in the present day, morphology can gain an integrative function for seemingly heterogeneous dimensions and fields across the sciences - just as it was already able to serve Goethe as a unifying bond between his supposedly separate practices as poet, artist and scientist.
