Are there other means of persuasion to Aristotle did not discuss?

There is one more. Aristotle spoke of the three, Ethos, Pathos, and Logos. The fourth one is Kairos, and it is basically appealing to the sense of time and place. It is when you persuade your audience that if they don't support you at that moment, there will never be a chance again to do it, so they decide to support you.
