a big part of common sense knowledge is heuristics about different types of processes to use for different types of problem
Push: �common sense� vs �commonsense� � the second is a technical/specialist modifier
Steve: problem solving vs common sense?
common sense is often what you need as the ingredients for solving a problem � problem-solving as goal-satisfaction
if you�re going to have a theory of memory, maybe you need a theory of forgetting

common sense community
forbus! � northwestern � using equations etc. to model common sense physics
ben kuijpers - texas
attacks cognitive science
says they don�t simulate
lack interesting function-concepts
still basing their models on old AI ideas
their plan is to have 3 different ideas for doing everything � neural nets can never do that
I don�t understand why he�s anti self-organisation
seems to have implied that kids don�t do that much self-organisation
