Various aspects of van Fraassen's constructive empiricism are discussed. His concept of observability is said to have opened few unresolvable dilemmas. It is because of the confusion between observable/non-observable and testable/metaphysical distinctions. Finally, the constructive empiricist is said to have failed in his attempt at reducing the metaphysical component of science.

According to Bas van Fraassen, scientific realists and anti-realists disagree about whether accepting a scientific theory involves believing that the theory is true. On van Fraassen’s own anti-realist empiricist position, accepting a theory involves believing only that the theory is correct in its claims about observable aspects of the world. However, a number of philosophers have argued that acceptance and belief cannot be distinguished and thus that the debate is either confused or trivially settled in favor of the realist. In (...) addition, another set of philosophers have argued that van Fraassen’s empiricist position appeals to an unmotivated distinction between observable and unobservable aspects of the world. This paper aims to reconstruct a van Fraassen-style empiricism about scientific acceptance that avoids these two objections – reconstructed empiricism. (shrink)
