If the meaning of communication is

to convey information or knowledge

from one person to another,

then the essence of communication is

'to make something common'

Dialogue as a special kind of communication,

is to 'make something IN common'

Or 'creating something new together'

But in most cases there is a HUGE problem

in the exchange of meaning between people.

Meanings are similar but not identical.

Which can be a real problem if people get to focus

on just their own meaning.

But if done right, it can also lead to something new.

Observing the differences

you might see something new

that is relevant to both views.

Go back and forth with the continual emergence

of new content that is common to both participants.

Each has to be interested primarily

in truth and coherence,

and be ready to drop old ideas and intentions.
