    On the Purity of the Art of Logic
    Book Description:

    This is the first complete English translation ofOn the Purity of the Art of Logic,a handbook of logic written in Latin by English philosopher Walter Burley (c.1275-1344/5). The work circulated in the Middle Ages in two versions, a shorter and a longer one, both translated here by Paul Vincent Spade. The translations are based on the only complete edition of Burley's treatises, corrected by Spade on the basis of one of the surviving manuscripts. The book also includes an extensive introduction, explanatory notes, a table of corresponding passages between the two versions, a select annotated bibliography, and three indexes.A contemporary of John Duns Scotus and William of Ockham, Burley was active at the universities of both Paris and Oxford. He became one of the most important figures in the transformation of medieval logic and semantics that took place in the early fourteenth century. Burley used new tools and techniques of logical and semantical analysis, yet in many cases he used them in defense of traditional views, such as a realist metaphysical theory of "universals."On the Purity of the Art of Logicshows both these sides of Burley-the innovator and the conservative-as well as some of the ways in which his views corresponded or clashed with those of William of Ockham.

    Walter Burley (or Burleigh)¹ was a slightly younger contemporary of John Duns Scotus (c. 1266–1308) and a slightly older contemporary of William of Ockham (c. 1285–1347). Although nowadays he is discussed mainly in connection with intellectual currents at Oxford University, he also studied and taught at Paris for some sixteen years or more. If today he is not as well known as the more familiar figures of Scotus and Ockham to the generally educated reader, it is not through any fault of his. He was an important and influential philosopher in his own day, and a prolific author....

  4. The Shorter Treatise on the Purity of the Art of Logic
    (pp. 1-76)

    (1) (p. 199) I propose to compile, if God grants it, a kind of treatise on the purity of the art of logic, so that youths who are arguing about any problem at all can be trained and can quickly dispose of it. The little book will contain four parts. In the first part certain general rules will be set out to be used in what follows. The second part will deal briefly and succinctly with certain points about the sophistical art, the third part about the art of training students, and the fourth part about demonstrative art.

  5. The Longer Treatise on the Purity of the Art of Logic
    (pp. 77-292)

    (1) (p. 1) Assuming the significates of noncomplex terms,¹ in this tract I intend to investigate certain properties of terms, properties that are applicable to them only insofar as they are parts of propositions.

    (2) I divide this tract into three parts. The first is about the supposition of terms, the second about appellation, and the third about copulation. Supposition belongs to the subject, appellation to the predicate. Copulation belongs to the verb that couples the predicate with the subject. For these three are the integral parts of the categorical proposition, to which we turn before turning to hypotheticals. Hence...
