String theory has been the dominating research field in theoretical physics
during the last decades. Despite the considerable time elapse, no new testable
predictions have been derived by string theorists and it is understandable that
doubts have been voiced. Some people have argued that it is time to give up
since testability is wanting. But the majority has not been convinced and they
continue to believe that string theory is the right way to go. This situation
is interesting for philosophy of science since it highligts several of our
central issues. In this paper we will discuss string theory from a number of
different perspectives in general methodology. We will also relate the
realism/antirealism debate to the current status of string theory. Our goal is
two-fold; both to take a look at string theory from philosophical perspectives
and to use string theory as a test case for some philosophical issues.Comment: Revised version published in Studies in History and Philosophy of
