What I think Aristotle means by truth does not always persuade is that when speaking and or arguing and truth is used for emphasis not necessarily persuasion. There does not always have to be persuasion in one’s writing or speech but there has to be a purpose and factors that drive that purpose home. Aristotle says that “enthymemes are at the body of persuasion while every other factor is put toward the external subjects;” truth is apart of the external subjects where most attention is given. Another statement form Aristotle is “if you were to have the most exact knowledge, it would not be very easy for us in speaking to use it to persuade,” and because there is knowledge in the speech given that means there will be teaching involved. Teaching is impossible when dealing with speeches because those who are listening are not there to get taught they want to see and hear the common beliefs shared amongst all. Take for example the presidential debates, the candidates are not going to talk on truth the whole time because they know they can’t provide it and the audience will not be interested. They provide speech about what the audience wants to hear and the commonalities they have between each other so they feel more connected and involved.
