By 1837, Marx was writing both fiction and non-fiction, having completed a short novel, "Scorpion and Felix", a drama, "Oulanem", as well as a number of love poems dedicated to Jenny von Westphalen, though none of this early work was published during his lifetime. Marx soon abandoned fiction for other pursuits, including the study of both English and Italian, art history and the translation of Latin classics. He began co-operating with Bruno Bauer on editing Hegel's "Philosophy of Religion" in 1840. Marx was also engaged in writing his doctoral thesis, "The Difference Between the Democritean and Epicurean Philosophy of Nature", which he completed in 1841. It was described as "a daring and original piece of work in which Marx set out to show that theology must yield to the superior wisdom of philosophy". The essay was controversial, particularly among the conservative professors at the University of Berlin. Marx decided instead to submit his thesis to the more liberal University of Jena, whose faculty awarded him his Ph.D. in April 1841. As Marx and Bauer were both atheists, in March 1841 they began plans for a journal entitled "Archiv des Atheismus" ("Atheistic Archives"), but it never came to fruition. In July, Marx and Bauer took a trip to Bonn from Berlin. There they scandalised their class by getting drunk, laughing in church and galloping through the streets on donkeys.
