Secondly, it aims to determine the grounds that could explain why the mathematics, due to the specificity of the philosophical method and the physical reception of music, respectively, are itself incapable to express the procedures of reason and of the art of sounds. Finally, it points out a similarity between reason and music concerning their common rejection of succumbing to the Schwärmerei, although the distance which divides them as two contrary ways to exercise and promote the life and its feeling.
