It is a process which brings order out of nothing but ourselves; it cannot be attained, but it will happen of its own accord, if we will only let it.
Every pattern we define must be formulated in the form of a rule which establishes a relationship between a context, a system of forces which arises in that context, and a configuration which allows these forces to resolve themselves in that context.
The patterns are not just patterns of relationships, but patterns of relationships among other smaller patterns, which themselves have still other patterns hooking them together---and we see finally, that the world is entirely made of all these interhooking, interlocking nonmaterial patterns.
You may be afraid that the design won't work if you take just one pattern at a time...There is no reason to be timid...The order of the language will make sure that it is possible.
Next, several acts of building, each one done to repair and magnify the product of the previous acts, will slowly generate a larger and more complex whole than any single act can generate.
It is essential, therefore, that the builder build only from rough drawings: and that he carry out the detailed patterns from the drawings according to the processes given by the pattern language in his mind.
