Putnam's internal realism

Internal realism is Putnam's attempt to avoid what he considers to be the pitfalls of metaphysical realism on the one hand and radical cultural relativism on the other, while taking key elements from both. In common with metaphysical realism, internal realism holds that there are things "out there," and that the truth is not simply legislated by us. And in common with relativism, internal realism holds that our assumptions and interests make a decisive contribution to our view of the world.
