PATHOS: Pathos is a quality of experience in life, or a work of art, that stirs up emotions of pity, sympathy, and sorrow. Pathos can be expressed through words, pictures, or even with gestures of the body. Pathos is a method of convincing people with an argument drawn out through an emotional response
ETHOS: Ethos is a way of appealing to an audience by showing one's credibility and ethical character. This is one of the three modes of persuasion in rhetoric, as distinguished by Aristotle, the other two being pathos and logos.
LOGOS: Logos, along with ethos and pathos, is one of the three "modes of persuasion" in rhetoric (the art of effective speaking or writing). Logos is an argument that appeals to an audience's sense of logic or reason. For example, when a speaker cites scientific data, methodically walks through the line of reasoning behind their argument, or precisely recounts historical events relevant to their argument, he or she is using logos.
