Unprofessional appeals.

So im writing a paper, and my teacher said I gotta use 4 different ways to convince the 'reader' (my teacher) that im right. So...

Which of these appeals can be considered unprofessional?
1) pathos
2)logos
3)ethos
4) image
5) ethics

Personally, I'd have to say logos, because it's more of a philosophy or a theology without substantial fact, and in a manner of professionalism, fact is one of the most important factors in proving your case, whatever that case may be.

I thought it might be ethics? because your using your own personal ethics. right?

You can view it that way, too...my own personal opinion is that ethics are one of the foundations of acting and reacting in a professional manner.

Without ethics, you have lack of morality.

so which one is more unprofessional?

thanks for being honest and not talking out your ears, alvina. hahaha

Pathos is by far the most unprofessional thing. I am finding it very hard to believe that anyone can say otherwise. Pity is very unprofessional.
