The human mind in all countries having gone to the uttermost limit of its own capacity, flushed with its conquests, haughty after its self-assertion … - Louis Sullivan

High ideals make a people strong. … decay comes when ideals wane.

Whether it be the sweeping eagle in his flight, or the open apple-blossom, the toiling work-horse, the blithe swan, the branching oak, the winding stream at its base, the drifting clouds, over all the coursing sun, form ever follows function, and this is the law. Where function does not change form does not change. The granite rocks, the ever brooding hills, remain for ages; the lightning lives, comes into shape, and dies in a twinkling. It is the pervading law of all things organic and inorganic, of all things physical and metaphysical, of all things human and all things superhuman, of all true manifestations of the head, of the heart, of the soul, that the life is recognizable in its expression, that form ever follows function. This is the law.

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.
