204 THE HUMANITY OF WORDS
operations which need to be performed by human beings. Even i the desired end ensues, we can never be positive that the instituted means gave rise to the end. The end may have resulted from factors unknownor even unknowable. But, as Dewey points out in his Logic: The Theory of Inquiry (1938), the absence of verification does not minimize the importance of the means to end hypothesis. Verifiability is not so important, he says, as the directive power of the hypothesisof the verbal plan that directs activity toward the realization of a foreseen goal.
The means to end pattern has a high or lower degree of predictability, depending on the nature of the subject matter.
The means to end hypothesis has a high degree of predictability when it rests upon a cause to effect pattern in which the terms designate and denote that relationship.
The means to end hypothesis has a lower degree of predictability when it rests upon an imputed cause to effect pattern. In such a case, the communicator will keep the procedure open-end and subject to correction on the basis of new information.
44. A FIELD THEORY OF COMMUNICATION DEFINED
What is field theory of communication, and how does it differ from other theories?
Field theory of communication provides the semantic techniques by which to use change in the interest of purpose. These semantic techniques are: 1. feedforward, and 2. feedback, both of which are exercised most effectively through the use of verbal patterns.
Look, first, at this analogical model of a face-to-face communication process:
