No complete architecture has yet appeared in the history of the world because men, in this form of art alone, have obstinately sought to express themselves solely in terms either of the head or of the heart.
I hold that architectural art, thus far, has failed to reach its highest development, its fullest capability of imagination, of thought and expression, because it has not yet found a way to become truly plastic: it does not yet respond to the poet's touch. That it is today the only art for which the multitudinous rhythms of outward nature, the manifold fluctuations of man's inner being have no significance, no place.
