to control in the interest of purpose. This means that he must use his perception of changeinside himself and outside himselfconstructively. And this is why we require a field theory of communication.
We require a field theory of communication because process is an aspect of life and because change is an ingredient of the communication process. We require a field theory of communication because control of change in the interest of purpose can be effected only by the control of the cross organization between the communicator and the relevant social environment. A field theory of communication^ conformsNB with a field theory of personality which admits of no strict boundary between the communicator and the relevant environment.
Field theory of communication is characterized by its attention to;
(1) Patterns in the actual world of people and things as perceived by the abstractive nervous system;
(2) Verbal patterns that designate "real" patternsactual, possible, or even plausible; and
(3) Control of the changing patternthe cross organization of the relevant situation-as-a-whole.
In cross organization, the link between the verbal world and the actual world is structure, as Korzybski points out in Science and Sanity. Two things that have their structural characteristics in common, he says, "have all their logical characteristics in common." (page 60) Since the communicator must use words (first thought, then said) by which to relate his inner life constructively to the relevant environment, It is essential to explore the nature of thinking, thus to determine, in so far as we can, how best to establish that link between the verbal world and the actual world.
