Any event or group of events may be viewed from different degrees of abstraction. A man jumps from a bridge. The psychologists make abstraction from everything except the mental state which prompted the suicide; the biologists abstract from everything except the dying organism; while the physicists are interested in the man, not as mind, or as organism, but as a falling body.
( Fulton J. Sheen )
