 For Windelband, however, the difference between the two kinds of knowledge has to do with its aim and method as well. Cultural-historical knowledge is not concerned with a phenomenon because of what it shares with other phenomena, but rather because of its own definitive qualities. For values, which form its proper subject, are radically subjective, concrete and individualistic. Unlike the “nomothetic” knowledge that natural science seeks, what matters in historical science is not a universal law-like causality, but an understanding of the particular way in which an individual ascribes values to certain events and institutions or takes a position towards the general cultural values of his/her time under a unique, never-to-be-repeated constellation of historical circumstances. Therefore, cultural-historical science seeks “ideographic” knowledge; it aims to understand the particular, concrete and irrational “historical individual” with inescapably universal, abstract, and rational concepts. Turning irrational reality into rational concept, it does not simply paint (abbilden) a picture of reality but transforms (umbilden) it. Occupying the gray area between irrational reality and rational concept, then, its question became twofold for the Neo-Kantians. One is in what way we can understand the irreducibly subjective values held by the historical actors in an objective fashion, and the other, by what criteria we can select a certain historical phenomenon as opposed to another as historically significant subject matter worthy of our attention. In short, the issue was not only the values to be comprehended by the seeker of historical knowledge, but also his/her own values, which are no less subjective. Value-judgment (Werturteil) as well as value (Wert) became a keen issue.
