title: Logic and evaluation theory.
abstract: With this series of papers, evaluators are being called to substantiate the rationale and warrant for their own evaluative actions in ways parallel to how evaluators question the logic of program interventions, both as designed and as implemented. This endeavor is timely, appropriate, and important. In these comments, I raise modest questions about the logical constitution of an evaluation theory and about what is missing from a textual reading alone of such theory.
