In addition to helping with the "Zeitschrift", Adorno was expected to be the Institute's liaison with Benjamin, who soon passed on to New York the study of Charles Baudelaire he hoped would serve as a model of the larger "Arcades Project". In correspondence, the two men discussed the difference in their conceptions of the relationship between critique and artworks that had become manifest through Benjamin's "The Work of Art in the Age of its Technical Reproducibility". At around the same time Adorno and Horkheimer began planning for a joint work on "dialectical logic", which would later become "Dialectic of Enlightenment". Alarmed by reports from Europe, where Adorno's parents suffered increasing discrimination and Benjamin was interned in Colombes, they entertained few delusions about their work's practical effects. "In view of what is now threatening to engulf Europe," Horkheimer wrote, "our present work is essentially destined to pass things down through the night that is approaching: a kind of message in a bottle." As Adorno continued his work in New York with radio talks on music and a lecture on Kierkegaard's doctrine of love, Benjamin fled Paris and attempted to make an illegal border crossing. After learning that his Spanish visa was invalid and fearing deportation back to France, Benjamin took an overdose of morphine tablets. In light of recent events, the Institute set about formulating a theory of antisemitism and fascism. On one side were those who supported Franz Leopold Neumann's thesis according to which National Socialism was a form of "monopoly capitalism"; on the other were those who supported Friedrich Pollock's "state capitalist theory." Horkheimer's contributions to this debate, in the form of the essays "The Authoritarian State", "The End of Reason", and "The Jews and Europe", served as a foundation for what he and Adorno planned to do in their book on dialectical logic.
