A dialogue is a written conversation between two or more characters that represent various views in an argumentative discussion. A dialogue is an argument. The reader is intended to follow through the discussion as a kind of participant. But the reader's participation should cause the reader to actively and seriously consider the views the different characters present. This can be a very persuasive device. You should pay close attention to the views the characters forward and how their views may subtly change as they debate whatever issue is being discussed. Try to identify the author's perspective. For instance, in David Hume's "Dialogues Concerning Natural Religion" (Hume was an 18th century philosopher) Hume's view is thought to be argued through the character of Philo.
