Abstraction is the technique we use to deal with complexity. What is the proper kind and level of abstraction for complex software agents? We think it would be reasonable to endow agents with a philosophy. Then, by understanding their philosophies, we can use them more effectively. To endow agents with ethical principles, developers need an architecture that supports explicit goals, principles and capabilities, as well as laws and ways to sanction or punish miscreants. All of the ethical approaches described in this article are single-agent in orientation and encode other agents implicitly.

Ordered macroporous Sr0.5Sm0.5CoO3 structrures with an average pore size of 140 nm have been prepared using closepacked arrangement of monodispersed polystyrene spheres as templates. A fuel cell using ordered macroporous Sr0.5Sm0.5CoO3 as the cathode, gadolinia-doped ceria (GDC) film as the electrolyte, and GDC–NiO as the anode generated maximum power densities of 150, 196 and 267 mW/cm2 at 500, 550 and 600 °C, respectively.
