Appeal To Authority

　　To appeal to authority is to cite an experts opinion as support for ones own opinion. This method of thought is not necessarily fallacious. Clearly， the reasonableness of the argument depends on the expertise of the person being cited and whether she is an expert in a field relevant to the argument.

　　Appealing to a doctors authority on a medical issue， for example， would be　reasonable; but if the issue is about dermatology and the doctor is an orthopedist， then the argument would be questionable.

　　Personal Attack

　　In a personal attack ， a persons character is challenged instead of her opinions.

　　Example：

　　Politician： How can we trust my opponent to be true to the voters? He isnt　true to his wife!

　　This argument is weak because it attacks the opponents character， not his p　ositions. Some people may consider fidelity a prerequisite for public office History， however， shows no correlation between fidelity and great political leadership.

　　I would fly you to the moon and back

　　If youll be if youll be my baby

　　Got a ticket for a worldswhereswe belong
