Frege and the Logic of the Historical Proposition

This article argues that history played a larger role in the thought of Gottlob Frege than has usually been acknowledged. Frege’s logical writings frequently employed statements about the past as examples that included references to historical persons. Frege also described history as a science and argued that historical propositions could support valid inferences and reliably identify historical persons and events. But Frege’s eternalist theory of reference, designed primarily for formal concepts and objects, struggled to accommodate such propositions. Identifying an objective referent for the subjectivity of historical actors was particularly problematic. The article suggests that Frege’s writings are interesting for the philosopher of history for at least two reasons: first, his work is clarificatory when considering the key features that historical propositions must have to count as objective knowledge, and second, it foreshadowed the issues with historicity that analytical philosophy experienced in the twentieth century. It concludes that the problems Frege raised exposed the need for a new concept of inter-subjectivity to replace his own Platonic foundation for objectivity.
