From Anatomy of the State — surrounding passage

Many and subtle are the ideological weapons that the State has wielded through the centuries. One excellent weapon has been tradition. The longer that the rule of a State has been able to preserve itself, the more powerful this weapon; for then, the X Dynasty or the Y State has the seeming weight of centuries of tradition behind it. 16 Worship of one’s ancestors, then, becomes a none too subtle means of worship of one’s ancient rulers.

“The greatest danger to the State is independent intellectual criticism; there is no better way to stifle that criticism than to attack any isolated voice, any raiser of new doubts, as a profane violator of the wisdom of his ancestors.”

Another potent ideological force is to deprecate the individual and exalt the collectivity of society. For since any given rule implies majority acceptance, any ideological danger to that rule can only start from one or a few independently-thinking individuals. The new idea, much less the new critical idea, must needs begin as a small minority opinion; therefore, the State must nip the view in the bud by ridiculing any view that defies the opinions of the mass.
