the action of something being made, done or caused to happen again. Used in this sense to denote unnecessary or wasted motion. In Scientology, duplication is also used to describe the action of reproducing something exactly. For example, if Person A communicated the concept of a cat to Person B and Person B got the exact sameconcept of a cat without any alteration, Person B would be said to have duplicated what was originated by Person A. —How T o Live Though an Executive.
