"Demosthenes could not resist the temptation, but admitting the present, ... he surrendered himself up to the interest of Harpalus." Tsatsos defends Demosthenes's innocence, but Irkos Apostolidis underlines the problematic character of the primary sources on this issue—Hypereides and Dinarchus were at the time Demosthenes's political opponents and accusers—and states that, despite the rich bibliography on Harpalus's case, modern scholarship has not yet managed to reach a safe conclusion on whether Demosthenes was bribed or not. m. Blass disputes the authorship of the following speeches: Fourth Philippic, Funeral Oration, Erotic Essay, Against Stephanus 2 and Against Evergus and Mnesibulus, while Schaefer recognises as genuine only twenty-nine orations. Of Demosthenes's corpus political speeches, J. H. Vince singles out five as spurious: On Halonnesus, Fourth Philippic, Answer to Philip's Letter, On Organization and On the Treaty with Alexander. n. In this discussion the work of Jonathan A. Goldstein, Professor of History and Classics at the University of Iowa, is regarded as paramount. Goldstein regards Demosthenes's letters as authentic apologetic letters that were addressed to the Athenian Assembly.
