"The original meaning of 'whole' is healthy, unhurt and complete. In this sense, the wholeness of something can be viewed as the systematic completeness of its parts, as well as the entirety of its characteristics and relationships to each other. Viewing and treating a topic (...) in its completeness implies a comprehensive, far-sighted and very forward-looking consideration of as many aspects and correlations as possible."

>Source(quote: Ganzheitlichkeit als Art der Betrachtung (Wholeness as a Method of Viewing)<
