"Let make explicit one presupposition before we begin in earnest. I assume that AI in general, along with the AI part of the gaming industry in particular, have realized that non-logicist AI isn't magic. What do I mean? I mean that people should be smart enough now to concede that no system is going to automatically learn, through subsymbolic, numerical processing, how to, say (and this is the challenge I'm going to focus on below), assemble robust, autonomous characters in a game. Automated learning through artificial neural networks and genetic algorithms are fine for certain applications, but gone, I assume, are the days of wild optimism about the ability of such learning techniques to automatically yield (to stick with this example) full-blooded NPCs.4 We really only have two overall approaches to AI: one based on logic, and one based on subsymbolic processing. This paper is written from the perspective of logic. If you think that you have a way of solving the problems I'm talking about without using logic, I wish you well."
