The change of medieval philosophy, known to have taken place in the 14th century, is accompanied by a new and extensive application of terminist logic and by a growing importance of the university of Oxford. This essay asks the question whether this development can be explained as a development of a specific English tradition within medieval logic. In the first part of the paper it is briefly shown that a certain discontinuity can be observed in the most important continental intellectual (...) centers; the 'sociological' conditions which make possible such distinct local traditions within the general development of medieval scholasticism are considered shortly. The second and larger part of the paper is a census of the English contribution to logic before Ockham, ordered according to the various literary genres: Summulae, Syncategoremata/sophismata, Grammar, Commentaries on the Organon. This census tends to prove that terminist logic had a continuous tradition in Oxford, a fact which may account for the preponderance of Oxford logic in the early 14th century. (shrink)
