Louis Sullivan Quote

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 upon emerging from the prior dark age, is now nearing a new phase, a phase inherent in the nature and destiny of things.
The human mind, like the silk-worm oppressed with the fullness of its own accumulation, has spun about itself gradually and slowly a cocoon that at last has shut out the light of the world from which it drew the substance of its thread. But this darkness has produced the chrysalis, and we within the darkness feel the beginning of our throes. The inevitable change, after centuries upon centuries of preparation, is about to begin.
