Book Note: Persuasion and Rhetoric by Carlo Michelstaedter #20

And not only do the others believe them persuaded, for to the ignorant "being of good faith" is a synonym for "being persuaded," but they themselves-if one excludes the sly-in the persuasion of wanting to conquer, taking their need itself as reason, are fooled by their own words. And deluding themselves into thinking that they are spreading their own ideas, they are unconscious instruments of society: `unknowing slaves.' 

Rhetoric perpetuates a diluted version of the Persuaded One's message, thus keeping others from self-persuasion. The cycle goes on and on so long as one does not seek self persuasion.
