The Many Faces of Putnam's Internal Realism

Putnam has developed several realisms in his life.We think that his recent view is a conjunction between realism and anti-realism,which he called 'internal realism'.If we want to know Putnam's internal realism correctly,we must clarify how he overcomes metaphysical realism,in which he argues against the subjectivity/objectivity dichotomy and the fact/value dichotomy.We mainly discuss the relationship between 'common-sense realism' and 'internal realism',and the relationship between 'pragmatic realism' and 'internal realism'.
