184 THE HUMANITY OF WORDS
Notice the hierarchical nature of the pattern. The for-mators on the highest level of abstraction make up the major parts; those on a lower level, the minor parts; those on yet a lower level, the subordinate parts, etc. Notice that details and examples of firsthand experience do not have a place in the pattern, however elaborate it may be. The communicator will use a formator that will make a place for details and examples when and where he needs them in his complete development.
The completeness of any formative structure is commensurate with the intention of the communicator with respect to a particular audience. But however brief or exhaustive the verbal pattern may be, there is always the semantic task of establishing the proper arrangement of appropriate formators. Two requirements of logic must be met in this semantic procedure:
(1) The formators that purport to isolate the classes (designated by general terms) must not overlap; and
(2) When two or more classes are subsumed under one broader formator, they should be on the same level of abstraction.
A verbal pattern is an arrangement of formators. Its function is to establish the arrangement of the separate elements of a communication, written or oral, without regard for the intrinsic nature of those separate elements.
But there is yet another aspect of the arrangement of formators that is basic to field theory of communication; while it is of first importance that the formators of a verbal pattern be arranged in logical hierarchical order there is also another requirement. It is essential for the communicator to understand the principle of organization that binds the separate formators together. A pattern gets its definitive
