There are actually several conficts within Pirandello's play. The conflict that sets the plot in motion is that between the author and his six characters. As the play begins, the characters directly address the audience to announce that they are on stage to look for a new author to complete their story as the one who created them has left their story incomplete. The characters also create a contrast with the actors wh will eventually come to embody them. They think they are more "authentic" than the actors. This initial situation creates a sense of conflict between reality and illusion, which is the main theme of the play. Like several other Modernist works, Six Characters in Search of an Author calls attention to its own fictional devices, dismissing, in spite of its characters' claim on their authenticity, all realistic pretences.
In addition, there are important conflicts among the six characters themselves: the Son is resentful against his father and his adoptive family; the Step-daughter, in turn, dislikes her step-father (whom she meets in the brothel where she has to work) and the Son because of his contempt.
