This is the semantic commitment of scientific realism.
What is an example of scientific realism?

What is the difference between scientific realism and instrumentalism?

Are there necessary a posteriori truths?
ARE THERE NECESSARY A POSTERIORI TRUTHS? that if one accepts Kripke’s views on rigid designators together with two other rather plausible assumptions, then one cannot accept the example that Kripke presents as a case of a necessary a posteriori truth.
What is the difference between priori and posteriori?
“A priori” and “a posteriori” refer primarily to how, or on what basis, a proposition might be known. In general terms, a proposition is knowable a priori if it is knowable independently of experience, while a proposition knowable a posteriori is knowable on the basis of experience.
