Alexander’s centers compared with BFO objects

A useful but limited analogy: BFO defines an object as a material entity that manifests causal unity and is maximal relative to the relevant kind of causal unity. Alexander’s centers likewise concern non-arbitrary unity, but they are not equivalent to BFO objects. Alexander permits centers to overlap and nest #A4LK2X to be weak or latent #KJBJ2D and to include spatial/immaterial configurations such as a square, courtyard, boundary, void, or positive space. In BFO these could fall under different categories—object, fiat object part, object aggregate, site, or spatial region—rather than all under object. BFO primarily asks what kind of entity something is and what grounds its unity; Alexander asks how strongly a configuration functions as a center within a relational field and how transformations strengthen that field #G8D7VX #GXVBDU The promising bridge is therefore not Center = Object, but: BFO supplies distinctions among entity and boundary types, while Alexander supplies graded, relational, multi-scale coherence and transformation.
