Moritz describes a dream that has been keeping him up at night, and Melchior realizes that Moritz has been having erotic dreams which Moritz believes are signs of insanity. To comfort the panicked Moritz, Melchior, who has learned sexual information from books, tells Moritz that all of the boys at their age get these dreams. Moritz, Melchior and the other boys – Ernst, Hänschen, Otto and Georg – share their own sexually frustrated thoughts and desires ("The Bitch of Living"). Moritz, who is not comfortable talking about the subject with Melchior, requests that he give him the information in the form of an essay, complete with illustrations.
