He commits modern realists to three metaphysical valuations or intrinsic kinds of knowledge of truth. Competent realists affirm that natural kinds exist in a mind-independent territory possessing 1) meaningful and 2) mappable intrinsic properties.Ontologically, scientific realism is committed to the existence of a mind-independent world or reality. A realist semantics implies that the theoretical claims about this reality have truth values, and should be construed literally.… Finally, the epistemological commitment is to the idea that these theoretical claims give us knowledge of the world. That is, predictively successful (mature, non-ad hoc) theories, taken literally as describing the nature of a mind-independent reality are (approximately) true.He labels these intrinsic valuations as "semi-realist", meaning they are currently the most accurate theoretical descriptions of mind-independent natural kinds. He finds these carefully qualified statements necessary to replace earlier realist claims of intrinsic reality discredited by advancing instrumental valuations.
