The earlier consideration of the phenomenological theory of intentionality made the distinction between phenomena and appearances. Phenomena are intended (or, to use von Bertalanffy’s word, conceived) as systems constituted by the perceived present and co-intended absent appearances. As such, they are attributed an identity by consciousness in its epistemological engagement with them. In order to extract some knowledge from the perception of appearances, some identity, and hence some epistemological unifier, must be intended or created-projected. In addition, appearances themselves, once abstracted from their designated phenomena, can be phenomena with attributable identities.
