Roberts contends that the positivists were right to believe that covering laws are indispensable in historical explanations but wrong to think that these laws apply to macro-events (such as wars and revolutions). Similarly, the humanists were right to declare that historians do not explain the occurrence of macro-events by subsuming them under covering laws but wrong to deny the role of covering laws in tracing the course of events leading to the macro-event. Roberts resolves this debate by showing that, though useless in explaining macro-events, covering laws are indispensable in connecting the steps in an explanatory narrative. He then sets forth the logic of an explanatory narrative, explores the nature of rational explanation, and distinguishes the logic of historical interpretation from the logic of historical explanation.
