 In the Latin West, as the universities developed in the 13th and 14th centuries, two forms for philosophical and theological speculation were incorporated into the curriculum, the disputed question and the Sentences Commentary. The De Fallaciis attributed to Aquinas defines a disputed question as a set of syllogistic arguments on different sides of a question to be resolved (Bazán 1985, 22). Bazán gives a more complete definition as follows: “a disputed question is a regular form of teaching, apprenticeship and research, presided over by a master, characterized by a dialectical method which consists of bringing forward and examining arguments based on reason and authority which oppose one another on a given theoretical or practical problem and which are furnished by participants, and where the master must come to a doctrinal solution by an act of determination which confirms him in his function as master” (Bazán 1985, 40). Disputations took place both privately between a master and his students, and publicly or “solemnly” at an event that replaced regular classes at the university and was attended by the larger university community. The latter practice was eventually codified by university statute, which prescribed that masters would hold a certain number of disputations at various times of the year, sometimes as frequently as once a week. Most scholars agree that the process came to be divided into two sessions. In the first session, supporting and opposing arguments for a given thesis or question were brought forward, and, in a preliminary way, clarified and determined by a student serving as the respondens under the supervision of the master. During the second session, the master himself would make the determination, give his answer and respond to all the opposing arguments. Some disputed questions we have in written form are clearly taken from the different stages in this process, either a reportatio of the first day’s session, some abbreviation of the debate, or one reflecting the master’s answer and response to opposing objections, redacted after the second day’s debate.
