I entered myself for a course of lectures by Professor Friedrich Thiersch on AEsthetics. He it was who had trained Heine to art, and I venture to say that in my case the seed fell on good ground. I took in every thought. His system agreed, on the whole, perfectly with that advanced in after years by Taine, and marvellously well with that set forth in the "Essays, Speculative and Suggestive," of J. A. Symonds--that is, it was eclectic and deductive from historical periods, and not at all "rhapsodical" or merely subjective. I bought the best works, such as Kugler's, for guides, and studied hard, and frequented the Pinacothek and Glyptothek, and I may say really educated myself well in the history of art and different schools of aesthetics. My previous reading, travel, and tastes fitted me in every way to easily master such knowledge. I also followed Becker's course on Schelling, but my heart was not in it, as it would have been two years before. The lectures of Professor Henry and Gmelin and true Science had caused in me a distrust of metaphysics and psychological systems and theories. I began to see that they were all only very ingenious shufflings and combinations and phases of the same old cards of Pantheism, which could be made into Theism, Pietism, Atheism, or Materialism to suit any taste. I was advancing rapidly to pure science, though Evolution was as yet unknown by the name, albeit the Okenites and others with their _Natur-philosophie_ were coming closely to it.
