Colloquium of the Dep of Theoretical Philosophy by Stephan Hartmann (Munich Center for Mathematical Philosophy/LMU):
The No Alternatives Argument (joint work with R. Dawid and J. Sprenger)
Scientific theories are hard to find, and once scientists have found a theory H, they often believe that there are not many distinct alternatives to H. But is this belief justified? What should scientists believe about the number of alternatives to H, and how should they change these beliefs in the light of new evidence? These are some of the questions that we will address in this paper. We also ask under which conditions failure to find an alternative to H confirms the theory in question. This kind of reasoning (which we call the No Alternatives Argument) is frequently used in science and therefore deserves a careful philosophical analysis.
