_association_, and this is correct. Association, indeed, may be
regarded as the more scientific term of the two; at any rate it
indicates more exactly what the sociologist deals with. A word may be
said also as to the meaning of the word _social_. The sense in
which this word will generally be used in this text is that of a
collective adjective, referring to all that pertains to or relates to
society in any way. The word social, then, is much broader than the
words industrial, political, moral, religious, and embraces them all;
that is, social phenomena are all phenomena which involve the
interaction of two or more individuals. The word social, then, includes
the economic, political, moral, religious, etc., and must not be thought
of as something set in opposition to, for instance, the industrial or
the political.

Society and its Products.--Beneath all the forms and processes of human
society lies the fact of association itself. Industry, government, and
civilization itself must be regarded as expressions of collective human
life rather than _vice versa_. Industry, for example, is one side
or aspect of man's social life, and must not be mistaken for society
itself. Industry, government, religion, education, art, and the like,
are all products of the social life of man. Among these coördinate
expressions of collective human life, industry, being concerned with the
satisfying of the material needs of men, is perhaps fundamental to the
rest. But this must not lead to the mistaken view that the social life
of man can be interpreted completely through his industrial life; for,
as has just been said, beneath industry and all other aspects of man's
collective life lies the biological and psychological fact of
association. This is equivalent to saying that industry itself must be
interpreted in terms of the biology and psychology of human association.
In other words, industrial problems, political problems, educational
