This paper takes the view that to be considered autonomous, a software agent must possess the means by which to manage its own motivations and so define new goals. Using the motivational theories of Abraham Maslow as a starting point, we investigate the role that argumentation processes might play in balancing the many competing aspects of a whole agent’s motivational agenda. This is developed into an Agent Argumentation Architecture (AAA) in which multiple “faculties” argue for different aspects of the total behavior of the Agent. The overall effect of these internal arguments then defines the overt “personality” of the agent.
