The act of isolation involved [in concept-formation] is a process of
abstraction: i.e., a selective mental focus that takes out or separates a
certain aspect of reality from all others (e.g., isolates a certain attribute
from the entities possessing it, or a certain action from the entities
performing it, etc.).
