Scientific Theories : Instrumentalism

The view that scientific theories do not describe reality and that they are mere tools for prediction describes instrumentalism. In a nutshell, the view describes scientific theories such as those of mathematical-logical conception among others. This essay will focus on instrumentalism, the mathematical-logical conception of scientific theories and how the view leads to instrumentalism of scientific theories. Philosophy of science springs around several enigmatic issues that philosophers are striving to unravel, deduce their meaning and bring into light their sole concepts. There is a view that the concepts of science, as well as the theories, is a factor determined by the extent to which these concepts and theories make precise empirical predictions or resolve technical problems. However, the same concepts and theories are never determined by their correspondence to authenticity in some sense or whether they are factual (Barker and Kitcher pp. 34). The expression that scientific theories should be reflected as gears for resolution of possible glitches rather than as an evocative description of the natural realm is a view that defines instrumentalism. Instrumentalism questions the sense of thinking of uncertain terms as conforming to external realism; a sense that opposes scientific realism. This refers to the view of scientific realism as not only a mere generator of scientific predictions but also to precisely describe the realm. Mathematical, logical conceptions of scientific theories provide a great deal in the explanation of scientific concepts and theories. In this sense, a set of axioms with their rational consequences defines a theory. This explanation is figured out in the history of natural sciences where Newton and Descartes tried to copy Euclid in the presentation of definitions of axioms, rules, and postulates. Development of new tools of mathematical logic presented a more clear understanding compared to Euclid’s axiomatization model which later failed (Barker and Kitcher pp. 34). Other philosophers who were experts in the field demonstrated how Euclidian model could be recast into a theory in a far logical sense. Their aim was further inclined towards working similarly on the other scientific theories such as the theories of evolution and relativity where the project was a success especially in the fields of physics. A general conception was inspired by the project where scientific theories promised to explain the proper use of technical languages. Apart from the reasonable and mathematical terms, scientific theories are self-evident schemes with suiting terminologies divided into a pair of parts. The observational language is the one that contains terms that can be studied and apply to things in the visible part of nature while the theoretical lingual involves the terms; illogical expressions that cannot be so erudite. Meaning is appended on the theoretical language because the underlying rules link its practical expressions to phenomena that can be observed. The theories so far have faced some technical difficulties with one of them being the idea that rational proposition shows that every philosophy has an opposition with axioms understood primarily in observational terms yet with observational consequences that are similar to those of the primary (Barker and Kitcher pp. 34). This has led to the adoption of instrumentalism by some philosophers as a response to such difficulties; the view that theories are tools for the expedient forecast of observable occurrence. Despite the fact that scientific realism and instrumentalism entangle to some degree, both have been explained to an amicable level that provides more than an average distinction. However, mathematical, logical conceptions, as well as other scientific theories, revolve around the concepts explained in the two antagonistic philosophical logics
