The search for an empirically adequate theory of quantum gravity - i.e. a theory that should cover a range of validity in which traditionally both quantum mechanical and gravitational aspects are relevant - has been dragging on now since the 1930s. The project deals with methodological-conceptual questions in the theory development and pursuit of a theory of quantum gravity: Can candidates already be meaningfully tested or compared with each other before the actual experiment? How systematically have the known candidates been searched for? Have meaningful directions of theory development been disregarded for purely contingent but substantively unjustified reasons?
