Pathos (appeal to emotion) is a way of convincing an audience of an argument by creating an emotional response to an impassioned plea or a convincing story. Logos (appeal to logic) is a way of persuading an audience with reason, using facts and figures.
Pathos appeals to the emotions of an audience and draws out the feelings that already reside in them. It is a technique used in rhetoric, literature, film, and other areas of narrative art.
