Rosenkrantz, R.D. Inference Method and Decision : towards a B : Towards a Bayesian Philosophy of Science (Synthese Library S.) -- Hardback

The traditional stum­ bling block for Bayesians has been to fmd objective probability inputs to conditionalize upon. To be sure, if we could agree on the correct probabilistic representation of 'ignorance' (or absence of pertinent data), then all probabilities obtained by applying Bayes' rule to an 'informationless' prior would be objective.
