Patterns mean "I have run out of language."
– Rich Hickey
Children of her type contrive the purest philosophies. Ada had worked out her own little system. Hardly a week had elapsed since Van’s arrival when he was found worthy of being initiated in her web of wisdom. An individual’s life consisted of certain classified things: "real things" which were unfrequent and priceless, simply "things" which formed the routine stuff of life; and "ghost things," also called "fogs," such as fever, toothache, dreadful disappointments, and death. Three or more things occurring at the same time formed a "tower," or, if they came in immediate succession, they made a "bridge." "Real towers" and "real bridges" were the joys of life, and when the towers came in a series, one experienced supreme rapture; it almost never happened, though. In some circumstances, in a certain light, a neutral "thing" might look or even actually become "real" or else, conversely, it might coagulate into a fetid "fog." When the joy and the joyless happened to be intermixed, simultaneously or along the ramp of duration, one was confronted with "ruined towers" and "broken bridges.
The key to complexity is systems-thinking, and the key to systems-thinking is patterns. The key to patterns is using them as a language – an idea I borrowed from architect and mathematician Christopher Alexander’s book ‘Notes on the Synthesis of Form’. – Tim Winton
