Its second part ends with a section on the titular thing "as a mastered moment," and considers the work of Solger and Tieck as instances of that thing "after Fichte."  That second part includes a section on the "world historical validity" of the titular thing, which is defined as "infinite absolute negativity."  The first part discusses the work of Xenophon and Aristophanes before considering the "daimon" of a figure to whom the work makes "constant reference," Socrates.  It was submitted as the author's dissertation in 1841, a few months before the author broke off his engagement with Regine Olsen.
