Summary. We have identified several approaches to
the concept of 
ideology 
and we have examined each
at some length. Each approach throws light on a
different dimension of the concept; together they re-
veal its extraordinarily rich and variegated intellectual
heritage. We may extrapolate from these approaches
a synthetic conception of ideology along the following
lines. Ideology is an emotion-laden, myth-saturated,
action-related system of beliefs and values about man
and society, legitimacy and authority, acquired as a
matter of routine and habitual reinforcement. The
myths and values of ideology are communicated
through symbols in simplified, economical, and efficient
manner. Ideological beliefs are more or less coherent,
more or less articulate, more or less open to new
evidence and information. Ideologies have a high po-
tential for mass mobilization, manipulation, and con-
trol; in that sense, they are mobilized belief systems.
