Abstract

This systematic development of the internal realist approach, first developed by Hilary Putnam, tries to steer a middle course between metaphysical realism and relativism. It argues against metaphysical realism that it is open to global skepticism and cannot cope with conceptual pluralism. Against relativism it is claimed that there are mind-independent constraints on the validity of our claims to knowledge. The book provides a moderately verificationist account of semantics and novel explanation of the idea of conceptual schemes. It is also argued that internalism realism can accommodate our common sense realist intuitions adn is also compatible with physicalism and naturalism.
