I agree that in order to be a persuasive writer, you have to keep in mind all the parts of rhetoric; logos, pathos, ethos and style. Although each of these have different meanings and are implemented in different ways, they are all connected. A writer cannot write about anything, the topic must appeal to the audience. The audience must also be listening to the speaker. The style of writing must also be understandable by the audience. Everything about logos, pathos, ethos and style are connected.
