The present research paper aims at clarifying the relationship between systematic thinking and historiographical practices in the works of the Neo-Kantian philosopher Wilhelm Windelband. According to the judgment of his successors, Windelband’s work is characterized by a systematical deficit grounded on an excess of historiographical labors. The aim of this study is to show that, in Windelband’s case the history of philosophy becomes a true impulse for systematical thinking. Besides, an attempt is made to show how Windelband's works make a (...) contribution to the elaboration of a concept of historical philosophy, that is, to carry out the historicization of philosophical thought.
