sociologists say. Such things cannot be passed physically from

would share a pie by dividing it into physical pieces. The
communication which insures participation in a common
understanding is one which secures similar emotional and

expectations and requirements.

Persons do not become a society by living in physical proximity,

institute a more intimate association between human beings
separated thousands of miles from each other than exists between
dwellers under the same roof. Individuals do not even compose a
social group because they all work for a common end. The parts
of a machine work with a maximum of cooperativeness for a common
result, but they do not form a community. If, however, they were
all cognizant of the common end and all interested in it so that
they regulated their specific activity in view of it, then they
would form a community. But this would involve communication.
Each would have to know what the other was about and would have
to have some way of keeping the other informed as to his own
purpose and progress. Consensus demands communication.

We are thus compelled to recognize that within even the most
social group there are many relations which are not as yet
social. A large number of human relationships in any social
group are still upon the machine-like plane. Individuals use one
