 Another factor at work was the doctrine of conceptions and assents. If, as was commonly accepted, argument is designed to bring about an assent, then one might ask what kinds of assent there are, and what variables in an argument lead to different kinds of assent. This doctrine was to replace the Alexandrian doctrine of the context theory, in which logic is taken to cover different material implementations of syllogistic reasoning, whether in demonstration, dialectic, rhetoric, poetics or sophistry. According to the Alexandrian version of the theory, a stretch of discourse was to be analysed according to the context in which it was found: in poetry, one expected to find false and impossible statements, in demonstration, necessary and true statements. The Arabic logicians were to reject this version, though they ultimately lost interest in the range of disciplines coordinated by the theory.
