learned to appreciate the theories of the author. Other documents related to the book would be referenced, such as Church councils, papal letters and anything else written on the subject, be it ancient or contemporary. The points of disagreement and contention between multiple sources would be written down in individual sentences or snippets of text, known as sententiae. Once the sources and points of disagreement had been laid out through a series of dialectics, the two sides of an argument would be made whole so that they would be found to be in agreement and not contradictory. (Of course, sometimes opinions would be totally rejected, or new positions proposed.) This was done in two ways. The first was through philological analysis. Words were examined and argued to have multiple meanings. It was also considered that the auctor might have intended a certain word to mean something different. Ambiguity could be used to find common ground between two otherwise contradictory statements. The second was through logical analysis, which relied on the rules of formal logic – as they were known at the time – to show that contradictions did not exist but were subjective to the reader. Scholastic instruction Scholastic instruction consisted of several elements. The first was the lectio: a teacher would read an authoritative text followed by a commentary, but no questions were permitted. This was followed by the meditatio (meditation or reflection) in which students reflected on and appropriated the text. Finally, in the quaestio students could ask questions (quaestiones) that might have occurred to them during meditatio. Eventually the discussion of questiones became a method of inquiry apart from the lectio and independent of authoritative texts. Disputationes were arranged to resolve controversial quaestiones. Questions to be disputed were ordinarily announced beforehand, but students could propose a question to the teacher unannounced – disputationes de quodlibet. In this case, the teacher responded and the students rebutted; on the following day the teacher, having used notes taken during the disputation, summarised all arguments and presented his final position, riposting all rebuttals. The quaestio method of reasoning was initially used especially when two authoritative texts seemed to contradict one another. Two contradictory propositions would be considered in the form of an either/or question, and each part of the question would have to be approved (sic) or denied (non). Arguments for the position taken would be presented in turn, followed by
