are committed. He links the pragmatic instrumental criterion to discredited anti-realist empiricist schools including logical positivism and instrumentalism. Chakravartty began his study with rough characterizations of realist and anti-realist valuations of theories. Anti-realists believe "that theories are merely instruments for predicting observable phenomena or systematizing observation reports;" they assert that theories can never report or prescribe truth or reality "in itself." By contrast, scientific realists believe that theories can "correctly describe both observable and unobservable parts of the world." Well-confirmed theories—"what ought to be" as the end of reasoning—are more than tools; they are maps of intrinsic properties of an unobservable and unconditional territory—"what is" as natural-but-metaphysical real kinds. Chakravartty treats criteria of judgment as ungrounded opinion, but admits that realists apply the instrumental criterion to judge theories that "work." He restricts such criterion's scope, claiming that every instrumental judgment is inductive, heuristic, accidental. Later experience might confirm a singular judgment only if it proves to have universal validity, meaning it possesses "detection properties" of natural kinds. This inference is his fundamental ground for believing in intrinsic value. 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 [valuations] 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. Science has destroyed for many people the supernatural intrinsic value embraced by Weber and Ellul. But Chakravartty defended intrinsic valuations as necessary elements of all science—belief in unobservable continuities. He advances the thesis of semi-realism, according to which well-tested theories are good maps of natural kinds, as confirmed by their instrumental success; their predictive success means they conform to mind-independent, unconditional reality.Causal properties are the fulcrum of semirealism. Their [intrinsic] relations compose the concrete structures that are
