Anti-foundationalism

Anti-foundationalism (also called nonfoundationalism) is any philosophy which rejects a foundationalist approach. An anti-foundationalist is one who does not believe that there is some fundamental belief or principle which is the basic ground or foundation of inquiry and knowledge.

Anti-foundationalism can be metaphysical (positing a ground of being or metaphysical foundation), ethical (positing some value or virtue as fundamental), epistemological (i.e. the foundationalist theory of justification) or apply to some other field with foundationalist theories.
