Question

What appeals to logic and ethics more successful?

Answer 1

I would assume you are trying to ask "what makes appeals to logic and ethics more successful?". In that case, it would be that they are founded in fact and have distinct argumentative points. This can be contrasted to appeals to emotion which may or may not be effective with the audience. As long as a logical argument is sound, and the audience is able to follow it, it will be more effective. Let me know if that doesn't answer your question.
