Scientific Realism and Instrumentalism

The debate between scientific realism and instrumentalism is another facet of the heated debate among philosophers of science about the nature of science itself and its rational justification and the possibility that it approximates honesty and its purpose. Scientific realism is "a philosophical view of science, consisting of three theses: the metaphysical thesis, that the world has a definite structure independent of reason; and the semantic thesis, that scientific theories must be taken at face value, i.e. What is unobservable is what the average person cannot see in this way, but needs observational tools, such as proton, electron, protein, magnetic field, etc. The metaphysical thesis means the objectivity of the world independent of the human mind, and the semantic thesis means that the scientific expression has a true value, whether it describes the observer or the unobservable. Instrumentality is "the view of science that theories should appear to be (useful) tools for organizing, classifying, and predicting observed phenomena. The value of theories lies entirely in what the theories tell us about the observed world. Instrumentalism comes in various forms, syntactic and semantic.....Traquitic instrumentalism takes a strong [radical] view, that theories are not meant to represent anything (deeper than experience), because there is nothing at the end of the spectrum deeper than experience (i.e., an unobservable reality) for theories to represent.... Semantic function takes theoretical sentences as meaningful, but only to the extent that they are (and because they are) perfectly translatable into assertions that contain only observational boundaries. If theoretical sentences are fully translatable, they are ultimately nothing but persuasive talk about those observational boundaries, and are thus ontologically harmless. In other words, we should not address theoretical sentences in the sense that they refer to unobservable entities, and therefore do not impose any obligations on us. Thus, science is only a theoretical tool to represent reality, in which honesty does not require, and is not a goal of science at all, but aims, as Van Frasen says, to “provide us with empirically appropriate theories.” By simply listing the definition of the two schools, the reader may realize that many of the objections we have mentioned in the previous two chapters to the objectivity of science will stand in front of scientific realism, and this is true, but the issue here is more specific, so scientific realism will provide additional arguments to support its principles, and the same is true of the tools. - Reza Zeidan. — Source: Published on Facebook's "Braheen Center" page
