A probabilistic theory of measurement uncertainty

``If we were not ignorant there would be no probability,
there could only be certainty. But our ignorance cannot
be absolute, for then there would be no longer any probability
at all. Thus the problems of probability may be classed
according to the greater or less depth of our ignorance.''
(Henri Poincaré)
