“To Urbain Grandier, for example, the Good Fairy had brought, along with solid talents, the most dazzling of all gifts, and the most dangerous -eloquence.
Spoken by a good actor - and every great preacher, every successful advocate and politician is, among other things, a consummate actor - words can exercise an almost magical power over their hearers. Because of the essential irrationality of this power, even the best-intentioned of public speakers probably do more harm than good. When an orator, by the mere magic of words and a golden voice, persuades his audience of the rightness of a bad cause, we are very properly shocked. We ought to feel the same dismay whenever we find the same irrelevant tricks being used to persuade people of the rightness of a good cause. The belief engendered may be desirable, but the grounds for it are intrinsically wrong, and those who use the devices of oratory for instilling even right beliefs are guilty of pandering to the least creditable elements in human nature.”
