We introduce a logic for reasoning about evidence that essentially views evidence as a function from prior beliefs (before making an observation) to posterior beliefs (after making the observation). We provide a sound and complete axiomatization for the logic; and consider the complexity of the decision problem. Although the reasoning in the logic is mainly propositional; we allow variables representing numbers and quantification over them. This expressive power seems necessary to capture important properties of evidence. © 2006 AI Access Foundation. All rights reserved;
