HOPP

Things can have various kinds of properties: properties such as shapes, colours, and sounds are low-order (or low-level) properties; properties that depend on their instantiation on the former are higher-order properties. Suppose, as is standard in the philosophical literature, that low-order properties are perceivable. Are some higher-order (or higher-level) properties perceivable too? The list of candidates is long, including natural and artificial kinds, organizational properties of different kinds, affordances, expressive and emotional properties, agential, intentional and even semantic properties, aesthetic and moral properties, and causal relations.
