Limits of historical and scientific knowledge.

The purpose of this paper is to suggest that subtle and essential uncertainties in language determine the limits of science and history, and thereby define the boundaries of research in the history of science. Historical research, in the strict sense of history as opposed to prehistory, begins with the examination of written records. There is a host of problems in the interpretation of the historical record, but underlying all of these is the simply stated yet complex question of the meaning of words in historical documents. Since this is where the practice of history begins, this problem delimits the boundaries of historical knowledge. In this paper, I will examine structural ambiguities in the meaning of words, explain how they arise, and provide independent evidence for the validity of the analysis.
