“The language of the totalist environment is characterized
by the thought-terminating cliché. The most far-reaching
and complex of human problems are compressed into brief, highly
reductive, definitive-sounding phrases, easily memorized and easily
expressed. These become the start and finish of any ideological
(Robert Jay Lifton, Thought
Reform and the Psychology of Totalism)
Also, completely unrelated, George Lakoff on "self-righteousness":
"The self-righteous person's superfluity of moral credit
is the basis of his discourse. He presupposes his own moral values
and his own righteousness as a condition of conversation. The
effect of this is that anyone talking to a self-righteous person
must either agree with his moral values and act equally self-righteous,
or face being put in a morally inferior position in the discourse."
(Lakoff, Moral Politics; my bold emphasis - ALP).
