Miller makes a valid point that the Ethos, Logos and Pathos are interconnected. One cannot exist  without the other and when they are together, they rotate around one another. In the other words, an essay cannot make sense if the writer(the ethos) just writes to the the audience(the pathos) without having an argument(the logos) that is valid. This also forms the basis of a conversation. Two people cannot have an conversation without having a topic to focus on and talk about . The Ethos and Pathos cannot connect without the Logos. There would be no flow of organized ideas.
