Is The Goal of Scientific Research to Achieve Truth?
Except in special cases, most scientific researchers would agree that their results are only approximately true. Nevertheless, to make sense of this, philosophers need adopt no special concept such as “approximate truth.” Instead, it suffices to say that the researchers’ goal is to achieve truth, but they achieve this goal only approximately, or only to some approximation. Other philosophers believe it’s a mistake to say the researchers’ goal is to achieve truth. These “scientific anti-realists” recommend saying that research in, for example, physics, economics, and meteorology, aims only for usefulness. When they aren’t overtly identifying truth with usefulness, the instrumentalists Peirce, James and Schlick take this anti-realist route, as does Kuhn. They would say atomic theory isn’t true or false but rather is useful for predicting outcomes of experiments and for explaining current data. Giere recommends saying science aims for the best available “representation”, in the same sense
