"We must first define an operation; and, if we are to be consistent, we must define it operationally. An operation is the performance which we execute in order to make known a concept. ... [Discrimination] is the sine qua non of any and every operation including that of denoting. In this sense discrimination is the fundamental operation of all science. ... We must define the criteria by which we determine the applicability of a term in a given instance and then ... maintain constant vigil against the human tendency to read into a concept more than is contained in the operations by which it is determined." (emphasis in original).

Electrical stimulation of the amygdala elicits many of the behaviors used to define a state of fear, with selected target areas of the amygdala producing specific effects (Fig. 1).

Only those constructs based upon operations which are public and repeatable are admitted to the body of science. ... A term or proposition has meaning (denotes something) if, and only if, the criteria of its applicability or truth consist of concrete operations which can be performed."
