Foundations of Historical Knowledge (Harper & Row, 1965) by Morton White, Professor Emeritus in the School of Historical Studies, is an examination of the covering law (CL) theory of objective historical explanation, a concept criticized by both historians and pragmatically-oriented analytic philosophers. White explores and attempts to alleviate this tension by emphasizing the interconnected conceptual role in historical inquiry of singular factual statements and parsing the essential semantical and syntactical theses of theorists on both sides.
