I am going with the assumption that by "set out" you are looking to identify elements of a speech that might make it a hortatory speech. Hortatory comes from Latin (hortari~encouraging) and means, urging to some course of conduct or action; exhorting; encouraging (dictionary.com). Closing arguments and/or summations in trials are usually classified as hortatory speeches since both sides want the jury or judge to vote in one way or the other. Atticus' summation at the end of Tom Robinson's trial is a good example of a hortatory speech since Atticus tries to appeal to the all-whte man jury by addressing the evidence, or lack there of. Atticus presents his case but needs to address the prejudices that may dictate how this jury (hardly one of peers of Tom Robinson) renders its decision.
