Historians nowadays doubt that medieval Scholastic scholars debated about how many angels can dance on the head of a pin. For years academics have found no evidence either for such a debate or a question that dealt with this issue.
In this connection, a funny fact should be added. According to the historian Robert Bartlett, “[t]here is a $5 standing bet for anyone finding any evidence of the question being asked in the Middle Ages” (73n4).
