Unit

"A unit is an existent regarded as a separate member of a group of two or more similar members" (ITOE p. 6). Implicit in the concept "unit" is the identification of a group, composed of a more than one existent. The important distinction between existent and unit is that an existent is independent of cognition, whereas the unit is the product of a consciousness "focusing on a particular attribute of the objects ..., then isolating them according to their differences, and integrating them as units into separate groups according to their similarities". (ITOE p. 6)
