Nonmonotonic Reasoning


Common sense reasoning is also imprecise in that it draws conclusions that might not be made if there were more information. Thus common sense reasoning is nonmonotonic. I will not go into the details of any of the proposals for handling nonmonotonic reasoning.

In particular, getting from the common sense informatic situation to a bounded informatic situation needs nonmonotonic reasoning.
