  Reicher (1998) acknowledges that if works are types, they cannot literally have spatiotemporal properties. With the aim of providing a more accurate restatement of ordinary talk about the perceptible qualities of works, she distinguishes between two different modes of predication. In an example of a first mode of predication, someone says ‘the table is rectangular’. This is contrasted to a different mode whereby we say, for example, ‘this work of art is determined as [ist bestimmt als] rectangular’. If a work of art has been determined as rectangular, then every realization of the work is rectangular. We can perceive a work’s realizations, as these are concrete objects or actions, but strictly speaking, we apprehend [erfassen] but do not perceive the type itself. (For background on this approach, see the entry on nonexistent objects.)
