Counterexamples are presented against the two standard probabilistic theories of evidence of Ch. 3. Various responses of defenders of these probabilistic theories are considered. It is argued that evidence, by contrast to probability, is a threshold concept that requires a certain amount of probability before any evidence is present. Patrick Maher's defense of the positive relevance view of evidence is presented and rejected.
