 Weber’s essays on methodology (1949) provide insight about these questions. Weber emphasizes the role that the scholar’s values play in his or her selection of a subject matter and a conceptual framework. So it is always open to historians of later generations to reevaluate prior interpretations of various aspects and periods of history. There is no general or comprehensive approach to defining the historical; there is only the possibility of a series of selective and value-guided approaches to defining specific aspects of history. We are always at liberty to bring forward new perspectives and new aspects of the problem, and to arrive at new insights about how the phenomena hang together when characterized in these new ways. This inherent selectivity of historical knowledge does not undermine the objectivity or veridicality of our knowledge; it merely entails that – like mathematics – history is inherently incomplete.
