Realism (philosophy)

Contemporary philosophical realism is the belief that some aspects of reality are ontologically independent of our conceptual schemes, perceptions, linguistic practices, beliefs, etc. Realism may be spoken of with respect to other minds, the past, the future, universals, mathematical entities (such as natural numbers), moral categories, the material world, and thought. Realism can also be promoted in an unqualified sense, in which case it asserts the mind-independent existence of the world, as opposed to skepticism and solipsism. Philosophers who profess realism often claim that truth consists in a correspondence between cognitive representations and reality.

Realists tend to believe that whatever we believe now is only an approximation of reality but that the accuracy and fullness of understanding can be improved. In some contexts, realism is contrasted with idealism. Today it is more usually contrasted with anti-realism, for example in the philosophy of science.

The oldest use of the term "realism" appears in medieval scholastic interpretations and adaptations of Greek philosophy.
