"Often during our journey I heard William mention "the simple," a term by which some of his brothers denoted not only the populace but, at the same time, the unlearned. This expression always seemed to me generic, because in the Italian cities I had met men of trade and artisans who were not clerics but were not unlearned, even if their knowledge was revealed through the use of the vernacular. And, for that matter, some of the tyrants who governed the peninsula at that time were ignorant of theological learning, and medical, and logical, and ignorant of Latin, but they were surely not simple or benighted. So I believe that even my master, when he spoke of the simple, was using a rather simple concept. But unquestionably Salvatore was simple."
