This chapter provides an impression of the sort of issues that interested, united and divided philosophical schools in the second half of the twelfth century. It argues that Nominales formed a school in this sense, named after the trademark slogan genus est nomen, whereas Reales did not: any non-nominalist group could be thus called. The chapter suggests that Nominales were the spiritual children of Master Peter. Many school theorems are at first blush as outrageous as the Stoic paradoxes; they were meant to attract attention. In the competition for pupils a list of a school's paradoxical opinions may have had an advertising function similar to that of a restaurant menu displayed in the window. The Melun theorem belongs in a debate about molecular propositions that moves within a universe of problems established before men started to study the Elenchi.
