Question

Are logical arguments more persuasive than emotional and moral ones?

Answer 1

It depends on the audience.

To an objective, rational person, yes, logical arguments are more persuasive than emotional and moral ones.

But just consider how many times people resort to emotional instead of logical appeals to try to gain adherents. They are hoping to convince those who are swayed by emotions more than by logic, and so by using emotionally loaded terminology.

Answer 2

The best arguments use <I>both</I> emotional and logical ploys.

It also depends whether the audience is basically pro or con in terms of the topic. With either, the factors of credibility and trust are more important than the type of argument.

With pro people, a pro argument will suffice. With con people, not only do you need the pro argument, but follow it with con arguments (usually those of the audience) and the anti-con arguments.
