{"product_id":"de-obligationibus-book-hajo-keffer-9789004122482","title":"De Obligationibus","description":"This book presents a thorough reconstruction of the late-scholastic logical treatises De Obligationibus by the methods of modern logic and set theory. It defends the view that the treatises are intended to put forward a theory of disputation. Hajo Keffer's excellent monograph is the first full-scale treatment of the complete range of medieval treatises on Obligations, from the earliest known treatises of the mid-thirteenth century through to Paul of Pergula's tract from the early fifteenth century.","brand":"WoB","offers":[{"title":"GB \/ VERY_GOOD \/ INTERNAL","offer_id":50296952226065,"sku":"GOR013917231","price":6.6,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/9004122486.jpg?v=1768563341","url":"https:\/\/www.worldofbooks.com\/en-gb\/products\/de-obligationibus-book-hajo-keffer-9789004122482","provider":"World of Books ","version":"1.0","type":"link"}
