Two distinct notions of closure, and relatedly, of unity, might be invoked in aesthetic contexts. The weak notion of closure is that of boundedness: an entity with clear limits separating it from other entities is, in this sense, closed. This sense of closure comes to mind when Dewey mentions, of mere experience, that its elements ‘are neither definitely included nor decisively excluded’ (p. 40). This sense of closure generates a related sense of unity: the ten provinces and three territories of Canada, despite their cultural, geographic and linguistic diversity, are united, in this weak sense,.
