Visual form
In photography the structure can be literal: power lines across sky, railings through water, tile seams, curbs, frames and architecture dividing a more continuous field.
Language and classification
A name, diagnosis, genre, title or category can behave in the same way. It creates a useful boundary around something that may exceed it.
Rules and systems
Laws, technical standards and institutional categories are also lines. They can organize reality powerfully without necessarily describing every material event that occurs inside the field.
Pattern discovered and pattern imposed
The corpus does not settle whether meaningful patterns are found, projected or created in contact between perceiver and material. Quantum Entendre and SKLĒROS/ANTI-SKLĒROS can be read as deliberately incompatible positions on that problem.
The wiki itself
An encyclopedia is also a framing device: it turns a continuous body of work into names, pages and categories. The best use of the principle here is practical humility—the map should be useful without pretending that its divisions are the work itself.
