Advanced synthetic characters don't merely evoke *beliefs* that they have various mental properties; rather, they must actually *have* such properties. You might (e.g.) believe a standard synthetic character to be evil, but you would of course be wrong. An *advanced* synthetic character, however, can literally *be* evil, because it has the requisite desires, beliefs, and cognitive powers. Our approach is based on the new RASCALS cognitive architecture, which uses simple logical systems (first-order ones) for low-level (perception & action) and mid-level cognition, and advanced logical systems (e.g., epistemic and deontic logics) for more abstract cognition.
