Handbook of the History of Logic - Vol 2 - Mediaeval and Renaissance Logic
The twelfth century, like the fourteenth, was arguably one of the great creative periods in the history of logic. Latin logic in the early Middle Ages, up to 1100, and the Latin tradition from Cicero to Boethius, Cassiodorus and Isidore, on which, along with some translations of Aristotle and Porphyry, it drew. It had no great logicians, but only influential ones, like Boethius, and outstanding philosophers, like Eriugena and Anselm, who were interested in logic. Yet it is worth studying, for at least two, very different reasons. First, twelfth-century logicians such as Abelard worked in a tradition that continued from the earlier medieval one: the text-books were the same and the methods and questions asked were related. Knowing about the Latin tradition and the early medieval background helps in understanding and assessing their ideas. Second, although the early medieval logicians may not have innovated in the contents of their teaching, they achieved something importantly novel with regard to the position of logic in the curriculum.
