The tree is an orderly and beautiful way of thinking and provides a simple and clear way to divide a complex whole into units, but it does not do justice to the structure of a naturally formed city, nor does it depict the structure of the city as we need it to be. - Cities are not trees. Christopher Alexander.
- Is not naturally formed “knowledge” likewise (Christmas) tree?
- Only those composed top down by one or a few people are trees
- A tree is not a tree if a lot of people have come together to make it.
- If you try to describe it as if it were a tree, you distort it.
- Made top-down v.s. made by many → Monastery and Bazaar like metaphor
