A political ideology is a set of principles aimed at establishing or maintaining a certain social system; it is a program of long-range action, with the principles serving to unify and integrate particular steps into a consistent course. It is only by means of principles that men can project the future and choose their actions accordingly.

Anti-ideology consists of the attempts to shrink men’s minds down to the range of the immediate moment, without regard to past or future, without context or memory—above all, without memory, so that contradictions cannot be detected, and errors or disasters can be blamed on the victims.

In anti-ideological practice, principles are used implicitly and are relied upon to disarm the opposition.
