Deliberate use of fallacy

[bennyboy]

Is it right to deliberately use fallacy in rhetoric if one thinks it will get a point accepted?

If you need fallacies to bring a point across, you haven't got a point to begin with. It's a different matter if you tailor your arguments to suit a particular audience. That can be achieved without outright lying, which fallacies are all about, if we're honest.

I guess it depends if you want to "win" logically, or actually manipulate the other person's ideas. I think to get someone to change something at their core, you're going to have to create a crack in the egg somehow-- and ideas almost never seem to do that. Either you have to completely mystify them, or they have to hit a crisis point. I suppose the death of a loved one would be the most common reason for people to leave-- or to join, for that matter-- a religious ideology. But perhaps a simulated crisis, via a very imaginative appeal to emotion, could have a similar effect?
