In contrast to the common tendency to separate Dilthey's early psychological writings from his later hermeneutical and historical works, this study seeks to demonstrate their essential continuity. Only by keeping these fundamental aspects of Dilthey's thought together can the fertility of his concepts and the overarching coherence of his approach be assessed. In this conviction, Makkreel advocates for the centrality of Dilthey's aesthetic writings and examines their philosophical implications—many of which are Kantian—for his theory of history.
