At the other end of the philosophical spectrum from Saint-Simonian ‘materialism’, though sharing its rhetoric of progress, was Hegelian Idealism. It influenced not only critics such as Franz Brendel and A. B. Marx, but also the ‘New German School’ of Liszt and Wagner. Though Hegel opposed Romanticism, applications of his aesthetics to music by Marx and Liszt remained closer to it, noting the convergence of music and literature on Romantic subjectivity and responding with the new genre of ‘programme music’. Another Romantic project, the ‘new mythology’, was realized in Wagner’s operatic Gesamtkunstwerk. Its more ‘realist’ approach to feeling was derived from Feuerbach’s post-Hegelian philosophy and little changed by Wagner’s later enthusiasm for Schopenhauer. Though overshadowed by his universalizing and exclusionary goal of a ‘purely human’ art (one that had no space for Jewish artists), Wagner’s aesthetic technique remained faithful to the idea of theatrical illusion inaugurated a century earlier by Rousseau and Diderot.
