ABSTRACT
The categories of logic, which in its present state of development is a specialized discipline like any other, require, if they are to be utilized with assurance, the same daily familiarity as those of any other discipline. The methodological details of that work are, so to speak, a diagnosis not by the physician but by the patient himself, and they are intended to be evaluated and understood as such. The categories of logic, which in its present state of development is a specialized discipline like any other, require, if they are to be utilized with assurance, the same daily familiarity as those of any other discipline. Eduard Meyer begins with a warning against the over-estimation of the significance of methodological studies for the practice of history. Meyer's own work must be carried on continuously with such heuristic means. What is meant here can only be that, the "components of an historical nexus" are a different thing from a "heuristic means.".
