Christopher Alexander – Fundamental Property 10: Gradients

“… Gradients must arise in the world when the world is in harmony with itself simply because conditions vary. Qualities vary, so centers which are adapted to them respond by varying in size, spacing, intensity and character. Daylight varies from the top floor of an urban building to the bottom floor: both windows and ceiling heights will probably have to vary to adapt to these conditions …

… These gradients will also form centers because the field-like character which is needed to make every strong center is precisely that oriented, changing conditions which ‘points’ towards the center of the center …

Buildings and artifacts without gradients are more mechanical. They have less life to them, because there is no slow variation which reveals the inner wholeness …

… although gradients are commonplace in nature … and in much traditional folk art, they are nearly non-existent in much of the modern environment. That is, I think, because the naive forms of standardization, mass production … and regulation of sizes … all work against the formation of gradients, and almost do not allow them to occur.

… In the towers of the Golden Gate Bridge there is a fine gradation of cell size, member size, ad plate thickness, from the top of the tower, to the bottom, to economize on steel, and place the most material where it is needed most by stresses.”
