Internal realism is a form of realism. What makes it a form of realism is:- a commitment to the existence of a real world external to human beings- a link between conceptual schemes and the world via real human experience; experience is not purely internal, but is constrained at every instant by the real world of which we are an inextricable part- a concept of truth that is based not only on internal coherence and “rational acceptability”, but, most important, on coherence with our constant real experience- a commitment to the possibility of real human knowledge of the world.What makes it “internal” is that it does not take an external perspective that stands outside of reality. Rather, it focuses on the way that we make sense of reality by functioning within it. The internalist perspective acknowledges the contribution of our conceptual schemes to our understanding of our real experiences in a real world.

Although internal realism is a form of realism, its internal character permits the existence of alternative, incompatible conceptual schemes. It is not a total relativism because of the limits placed on it by experience of the real world. It is not the case that “anything goes” in internal realism.
