Summary According to the so-called Starnberger Group1, the amenability of a science to science policy measures, conceptualised by the Group in terms of finalization , depends crucially on conditions intrinsic to the science not invariably present at every stage of its development. Finalization is possible only at junctures where the science in question faces methodologically divergent alternative lines of development. The most significant kind of case depends on the presence of completed , or classical , theories.
