The Concordance is designed around units of philosophical sense whose limits in the text are indicated to the line. Unlike research tools based merely on the occurrence of key words (e.g., cause), it provides precise and complete information about not only the location but also the diversity of content in all the items covered by its survey. Furthermore it provides the capability for tracing the family of topics to which a particular text may belong.

In short, the Concordance tells you as much as possible about a text before you look it up.
