 A second indirect perceptual motivation for existing and irreducible determinables reflects that our perception of macro-objects typically fails to register microdeterminate details. For example, shape is a paradigmatic determinable, but we do not perceive the shapes of trees, tables, and the like, in microscopic detail. In re this and the Sorites motivation, it is worth noting that even if perceived objects are themselves maximally determinate, perceptual experience may still motivate irreducible determinables; as Wilson notes,
