Abstract: The debate on scientific realism has raged among philosophers of science for decades. The scientific realist’s claim that science aims to give us a literally true description of the way things are, has come under severe scrutiny and attack by Bas van Fraassen’s constructive empiricism. All science aims at is to save the observable phenomena, according to van Fraassen. Scientific realists have faced since a main sceptical challenge: the burden is on them to prove that the entities postulated by our scientific theories are real and that science is still in the ‘truth’ business.
Comment: This article provides a very clear explanation of the scientific realism/Van Fraassen's constructive empiricism debate highlighting scientific realists' main difficulty, i.e find a proof that entities posited by science are real. Presupposes some background on the above mentioned themes.
