"Coercion, in the last resort,
is the "final" form of power, but of course we are by no means constantly
at the last resort. Authority (power that is justified by the beliefs of
the voluntarily obedient) and manipulation (power that is wielded unbeknownst
to the powerless) must also be considered, along with coercion. In fact,
whenever we think about power, the three types must be sorted out" (The
Causes of World War III, 1958, p. 41).
