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 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 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 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.
