According to Alexander "each pattern is a morphological law which establishes a set of relationships in space".
This process should link people’s microscopic needs and narratives to complex environmental and urban concerns.
Considering the design approach expressed in patterns and pattern languages, we recognize that patterns and their languages can enable or disable patterns at higher or lower system levels.
Speaking from systems science, we recognize that working with patterns and pattern languages as a design approach can absorb higher and lower systems levels' variety. Taking a recursive perspective is already a pattern on its own. There is no vaild reason to not considering higher order systems beyond buildings and towns. I believe that Christopher Alexander has shown to also support this way and has done significant work on it in his later work.
People cannot stay healthy in sick buildings or cities. Cities and neighborhoods cannot survive and cannot be sustainable in unsustainable countries or in an unsustainable planet. This is a consequence of thinking in patterns from a sustainability perspective.
TODO
Ask Ward Cunningham about learning and practicing pattern languages
Ask Ward if there are the associations between software patterns that form a pattern language. Ask if they could be organized in a Brain as I did with Alexanders 253 patterns. So that they form possible sentences.
