This comment responds to a suggestion that the degree to which evidence E proves that a proposition H is true should be expressed as the arithmetic difference between the posterior probability of the proposition, P(H|E), and the prior probability, P(H). It describes other expressions for probative value that rest on the likelihood ratio for H and that do include the prior probability.
