ABSTRACT

The main realism/anti-realism issue in the philosophy of science is the issue of scientific realism, concerned with the unobservable entities of science. However, there is also a more general issue, often known as “realism about the external world,” concerned primarily with the observable entities of common sense, but which spreads to scientific entities, both observable and unobservable. The issue of scientific realism is best approached from a perspective on the more general issue.
