||Concepts are the basic elements of thought. One of their primary functions is to connect the mind to the world; thus, to have a concept is to have available a way of thinking about something. There are concepts of particular individuals, general categories, natural kinds and artifacts, properties and relations, actions and events, and so forth. Concepts are also used in formulating beliefs, desires, plans, and other complex thoughts and judgments. They therefore play an important role in explaining cognitive processes such as categorization, inductive inference, causal reasoning, and decision making.
