In this article, I examine the enduring relevance of Heinrich Wölfflin’s approach to style, in light of the renewed interest in it among “postformalist” art historians. By delving into the theoretical foundations of the Principles of Art History, I explore Wölfflin’s Goethean interpretation of Kantian epistemology, revealing a conception of style characterized by its dynamic and symbolic “inner form” rather than mere static formalism. This analysis not only highlights affinities with Max Weber’s thought but also uncovers a previously overlooked connection to Wilhelm von Humboldt, offering valuable insights for current discussions on style.
