Input: I am referring to someone who makes people 'buy' what he says and gets things done by them through nothing but clever speech something one can describe as crafty or beguiling, but not fraudulent. I pondered over con man and con artist for a while but those terms seem to hold a hint of crime, so those terms won't fit in. I am wondering if there is a more suitable phrase or word.
Output:
Sophistry is crafty speech intended to deceive, not necessarily out and out lying. So then a sophist is someone who does it. This is mostly just to win arguments though, not necessarily to get people to do things. That would be a demagogue, but that is someone, yes, who is clever with words but in a very specific way, appealing to the listener's baser instincts.
