Measurement ommision

Measurement omission is the process by which one unites many existents under a common name, thus forming a concept. Existents contained under a certain concept, according to Ayn Rand's theory share common attributes, but differ in their specific measurements. To form a proper concept one identifies the CCD (Conceptual Common Denominator), which is the set of attributes common to the existents, and omit the specific measurements of these existents, in some case retaining a range of possible measurements.

Concepts form the basis of all abstract knowledge. The process of concept formation and measurement omission is thoroughly discussed in Ayn Rand's Introduction to Objectivist Epistemology.
