But Ridley shows that it is in their interest to form alliances. Cooperation is a recurring theme at all levels of the biological world. Ridley explains cooperation among organisms of different species by using game theory. Case-based reasoning is a form of analogical reasoning in which an episodic memory archives generalizations of all known cases and each new case spawns the search for a case that is similar. The new case is interpreted based on any similar cases and is used to furtherly refine the generalizations.
Interpretation is expectation-driven, based on what happened in previous cases.
Episodic memory contains examples of solutions, rather than solutions. The book surveys the most important systems built by Schank's team, thereby touching on MOPs and more advanced memory structures. Then shows its relations to natural logics, nonmonotonic reasoning and defeasible reasoning. When the mind has to categorize an object a variety of inferential processes occur, not limited to prototype recognition. Each of the main philosophers is given 3-4 pages.
