I would think that one of the strongest points of discussion between both characters is whether unity and transcendence is possible. Daru and Jackson experience different ends of this experience. For Daru, there is no unity, no sense of transcendence that helps to explain what it means to be a human being. He does not have any criteria that helps to fully explain the actions of the Arab or the choice he made. Daru would also lack the transcendent explanation to justify how his actions were misinterpreted with the message on his blackboard. In this, there is only fragmentation and disunity. Jackson, on the other hand, experiences a sense of totality and a sense of the complete with the ending of him dancing with his grandmother's regalia. In this instant, Jackson experiences a sense of the complete and of the totality that is present in consciousness. Both characters would engage in a discussion about whether there is a condition of unity and transcendence that is intrinsic to what it means to be a human being.
