Exist in concrete ideas, can also include abstract ideas. Contains links to other concepts and are also defined by links to other concepts. Can refer to a set of related exemplars/instances (these sets form categories) Help us understand new individual cases and can also help us identify special characteristics. Category is defined by a set of features that are singly necessary and jointly sufficient to constitute category membership. Does not end up working well for many situations. Many categories cannot be set for necessary features. Necessary features - must have all of the features to be in the category. Sufficient features - if it has the features, then it must be in the category. Problem: many categories have no set of necessary and sufficient features.
