The conceptual process through which sets and countersets are formulated. It implies previous apprehension of an object to be negated, in which the apprehension itself logically and automatically excludes the object to be negated from the set of either all validly knowable phenomena other than itself or all validly knowable phenomena in total. It is not a deliberate, conscious mental act.
