The dangers of non-empirical confirmation
... Unfortunately Dawid himself has done little to dispel this ambiguity, and this generates a problem for his views, for the following reason. Bayesian confirmation theory allows us to talk about the spectrum of intermediate degrees of credence between theories that are “confirmed”, in the common sense ...

From (1.2) one infers that local susy also introduces general coordinate transformations (with local translations being the infinitesimal form of these) and therefore gravity. ...

This singularity is seemingly a gauge artifact. It can be chosen, for example, to lie in different directions by making ...
