Anjan Chakravartty came indirectly to question the autonomous authority of instrumental value. He viewed it as a foil for the currently dominant philosophical school labeled "
scientific realism," with which he identifies. In 2007, he published a work defending the ultimate authority of intrinsic valuations to which realists 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 the primary subject matters of a tenable scientific realism. They regularly cohere to form interesting units, and these groupings make up the particulars investigated by the sciences and described by scientific theories. Scientific theories describe [intrinsic] causal properties, concrete structures, and particulars such as objects, events, and processes. Semirealism maintains that under certain conditions it is reasonable for realists to believe that the best of these descriptions tell us not merely about things that can be experienced with the unaided senses, but also about some of the unobservable things underlying them.Chakravartty argues that these semirealist valuations legitimize scientific theorizing about pragmatic kinds. The fact that theoretical kinds are frequently replaced does not mean that mind-independent reality is changing, but simply that theoretical maps are approximating intrinsic reality.The primary motivation for thinking that there are such things as natural kinds is the idea that carving nature according to its own divisions yields groups of objects that are capable of supporting successful inductive generalizations and prediction. So the story goes, one's recognition of natural categories facilitates these practices, and thus furnishes an excellent explanation for their success. The moral here is that however realists choose to construct particulars out of instances of properties, they do so on the basis of a belief in the [mind-independent] existence of those properties. That is the bedrock of realism. Property instances lend themselves to different forms of packaging [instrumental valuations], but as a feature of scientific description, this does not compromise realism with respect to the relevant [intrinsic] packages.In sum, Chakravartty argues that contingent instrumental valuations are warranted only as they approximate unchanging intrinsic valuations. Scholars continue to perfect their explanations of intrinsic value, as they deny the developmental continuity of applications of instrumental value.Abstraction is a process in which only some of the potentially many relevant factors present in [unobservable] reality are represented in a model or description with some aspect of the world, such as the nature or behavior of a specific object or process. ... Pragmatic constraints such as these play a role in shaping how scientific investigations are conducted, and together which and how many potentially relevant factors [intrinsic kinds] are incorporated into models and descriptions during the process of abstraction. The role of pragmatic constraints, however, does not undermine the idea that putative representations of factors composing abstract models can be thought to have counterparts in the [mind-independent] world.Realist intrinsic value as proposed by Chakravartty, is widely endorsed in modern scientific circles, while the supernatural intrinsic value endorsed by
Max Weber and
Jacques Ellul maintains its popularity throughout the world. Doubters about the reality of instrumental and intrinsic value are few. == See also ==
