both these so heterogeneous tendencies run parallel to each other, for the most part openly at variance, and continually inciting each other to new and more powerful births, to perpetuate in them the strife of this antithesis, which is but seemingly bridged over by their mutual term "Art"; till at last, by a metaphysical miracle of the Hellenic will, they appear paired with each other, and through this pairing eventually generate the equally Dionysian and Apollonian art-work of Attic tragedy.
