"Nevertheless, this meaning does not cover all that is signified by communication. For example, consider a dialogue. In such a dialogue, when one person says something, the other person does not in general respond with exactly the same meaning as that seen by the first person. Rather, the meanings are only similar and not identical. Thus, when the second person replies, the first person sees a difference between what he meant to say and what the other person understood. On considering this difference, he may then be able to see something new, which is relevant both to his own views and to those of the other person. And so it can go back and forth, with the continual emergence of a new content that is common to both participants. Thus, in a dialogue, each person does not attempt to make common certain ideas or items of information that are already known to him. Rather, it may be said that the two people are making something in common, i.e., creating something new together.
But of course such communication can lead to the creation of something new only if people are able freely to listen to each other, without prejudice, and without trying to influence each other. Each has to be interested primarily in truth and coherence so that he is ready to drop his old ideas and intentions and be ready to go on to something different when this is called for." David Bohm
