A second difficulty facing inference to the best explanation concerns the pools of theories regarding which judgments of relative explanatory efficacy are made. Combining the first and the second rsalism entails that an ideal scientific theory says definite things about genuinely existing entities. While most theories of explanation require that the explanans be true, pragmatic theories of explanation do not van Fraassen What is he leppin do?

Within philosophy of sciencethis view is often an rezlism to the question “how is the success of science to be explained? The crystalline spheres of ancient and early modern astronomy are simply obviated by Newtonian gravity.

The second option provides for the justification of theoretical beliefs. According to Popper, it can even show us what does exist instead. Liber Amicorum Pascal EngelGeneva: The changes in perception, conceptualization, and language that Kuhn associated with changes in paradigm also fuelled his notion of world change, which further extends the contrast of the historicist approach with realism.

Plato Aristotle Stoicism Epicureans.

The success of a theory in passing tests rationally warrants believing that it is closer to the truth than are theories that fail. Blackburn suggests that disputes about realism may have this character. In subsequent sections, I shall consider two significant challenges to realism.

Electrons, sceintific, and genes are examples normally thought to be real entities. For in general it is only in conjunction, not individually, that premises provide a basis for inference.


Scientific realism

There is a scientigic principle of speciation here, in that all three approaches are attempts to identify more specifically the component parts of scientific theories that are most worthy of epistemic commitment. Am I to induce, from my record of fallibility, that some of my present beliefs are false, although the evidence favors each of them and I have no grounds to doubt any?

Thus oxygen replaces phlogiston in the chemical theory of combustion.

But the particular properties attributed to this entity do not matter to the use of these laws in successful prediction. It has a confirmable component, but not only do confirmations of this component not confirm the other component; nothing could confirm the other component.

Observational propositions formulate the evidence by which theories scinetific judged, and the question has been whether this evidence is ever, in principle, sufficient for epis-temic commitment to theories.

One last take on the putative irresolvability of debates concerning realism focuses on certain meta-philosophical commitments adopted by the interlocutors. A result could be new and unknown, yet instantiate a general law presupposed in constructing the theory that predicts it. The fact that one and the same thing is apparently revealed by distinct modes of detection suggests that it would be an extraordinary coincidence if the supposed target of these revelations did not, in fact, exist.

Constructivists may also argue that the success of theories is only a part of the construction.


Longino, Helen,Science as Social Knowledge: Ambitious and tightly argued, A Novel Defense of Scientific Realism advances new positions on major topics in philosophy of science and offers a version of realism as original as it is compelling, making it essential reading for philosophers of science, epistemologists, and scholars in science studies.

More generally, any epistemology of science that does not accept one or more of the three dimensions of realism—commitment to a mind-independent world, scientifci semantics, and epistemic access to unobservables—will thereby present a putative reason for resisting the miracle argument.


These difficulties for logical positivism suggest, but do not entail, scientific realism, and lead to the development of realism as a philosophy of science.

Due to the wide disagreements over the nature of science’s success and the role of realism in its success, a scientific realist would agree with some but not all of scientifiic following positions. One challenge facing the epistemic version is that of articulating a concept of structure that makes knowledge of it effectively distinct from that of the natures of entities.

Scientific Realism (Stanford Encyclopedia of Philosophy)

This epistemic attitude has important metaphysical and semantic dimensions, and these various commitments are contested by a number of rival epistemologies of science, known collectively as forms of scientific antirealism. If observation is fallible, if observational judgments may themselves be objects of justification, if their evaluation invokes judgments outside their class, then the entire structure of justification collapses.

Rather, the criterion must be that the theory owes its success to this entity. Any theory that both fixes one of its parameters and declares it unmeasurable, or defines a parameter but leaves it unspecified, generates rivals.

Entity realism is especially compatible with and nicely facilitated by the causal theory of reference associated with Kripke and Putnam [b] Portraying scientific realism in terms of its ancient, medieval, and early modern cousins is at best misleading.

And certainly no corpuscular theory of light could be made to yield the unexpected bright spot.
