| [http://web.media.mit.edu/~minsky/ Marvin Minsky] has proposed the ''Emotion Machine'' architecture for [#Resourcefulness resourceful] commonsense thinking. Its main premise is that we need ''many'' ways to represent knowledge, solve problems and learn from mistakes. The underlying structure is a simple 6-layered organization, Model-6, where each layer has specialized '''critics''', that match patterns against a case-library, and '''selectors''', which arbitrate between the many different ways to respond to the problem. The job of a selector can vary from invoking a representation, a procedure, or debugging another representation.

| == Problem Solving in Model-6 == | |
| See Glossary for an explanation of the interrelated terms such as: goals, actions, problems and plans.
| |
| | |
| Problems are identified in terms of a rule-based system called the '''Critic-Selector''' model, where a critic observes the problem and a selector a way for it to be solved. In the Model-6 architecture, each layer specializes in a specific type of problem solving, so that each layer has a collection of critics that identify and propose ways to solve problems (see EM-ONE, for an implementation of the first three layers of Model-6 [http://web.media.mit.edu/~push/push-thesis.html Singh, 2005]).

| * ''Reactive Critics:'' Notice problems in the internal descriptions of the world and proposes goals.
| |
| * ''Deliberative Critics:'' Classify goals and propose ways to achieve them based on past epsiodes
| |
| * ''Reflective Critics:'' Recognize problems in the deliberative layer, including planning, and suggest ways to improve the problem sovling.
| |
| * ''Self-Reflective Critics:''

| * ''Self-Conscious Critics:''

| Where do high-level goals come from? High-level goals determine which problems an agent tries to solve, thus determining the subjects they "think about." It would
