In 1962 this book was provided to all Peace Corps Volunteers as part of their preparation for working abroad in non-U.S. cultures. Hall describes categories of communication which can be used to compare any two cultures. He discusses not only conversation but a number of non-verbal communication areas, with good illustrative scenarios, for the variety of attitudes toward personal space, use of time, interaction with authorities and the law, etc. His ideas seem congruent with Marshall McLuhan's famous concept of "the medium as the message." For me, --as a very verbal person, an artist, and a world traveler-- this book provided new and useful insights about inter- and intracultural communication. It is clearly organized, well written, fascinating, and as relevant to today's global communication as when it was written.
