Aristotle

Aristotle’s "ingredients for persuasion" – otherwise known as "appeals" – are known by the names of ethos, pathos, and logos. They are all means of persuading others to take a particular point of view.Ethos is an appeal to ethics, and it is a means of convincing someone of the character or credibility of the persuader.
Pathos is an appeal to emotion, and is a way of convincing an audience of an argument by creating an emotional response.
Logos is an appeal to logic, and is a way of persuading an audience by reason.
Examples--Ethos: (ethics)
-"As a doctor, I am qualified to tell you that this course of treatment will likely generate the best results."
-"The veterinarian says that an Australian shepherd will be the perfect match for our active lifestyle."
-"My three decades of experience in public service, my tireless commitment to the people of this community, and my willingness to reach across the aisle and cooperate with the opposition, make me the ideal candidate for your mayor."
Pathos: (emotion)
-"I’m not just invested in this community – I love every building, every business, every hard-working member of this town."
-"You’ll make the right decision because you have something that not many people do: you have heart."
-"You will never be satisfied in life if you don’t seize this opportunity. Do you want to live the rest of your years yearning to know what would have happened if you just jumped when you had the chance?"
Logos: (Logic, based on facts or evidence)
