Dilthey took some of his inspiration from the works of Friedrich Schleiermacher on hermeneutics, which he helped revive. Both figures are linked to German Romanticism. Schleiermacher was strongly influenced by German Romanticism which led him to place more emphasis on human emotion and the imagination. Dilthey, in his turn, as the author of a vast monograph on Schleiermacher, responds to the questions raised by Droysen and Ranke about the philosophical legitimation of the human sciences. He argues that 'scientific explanation of nature' ("erklären") must be completed with a theory of how the world is given to human beings through symbolically mediated practices. To provide such a theory is the aim of the philosophy of the humanities—a field of study to which Dilthey dedicated his entire academic career.
