khorismos
Khorismos is a term of Greek origin that refers to a separation or division. In ancient Greek philosophy, it was often used to describe the distinction between different realms of existence or concepts. For instance, Plato used khorismos to denote the separation between the world of Forms and the sensible world. This concept highlighted the idea that the Forms, representing perfect and unchanging essences, existed independently of and were distinct from the fleeting and imperfect objects we perceive through our senses.
The concept of khorismos implies a fundamental difference and an inability for the two separated entities
