Description:Recent scholarship on aivism has significantly expanded our knowledge of the religious dimensions of Medieval aiva movements. However, the philosophical aspects displayed by some of the texts produced in these milieux remain largely unrecognized. The present study helps fill this lacuna by exploring the sophisticated and original philosophical system elaborated by the Kashmiri aiva nondualists Utpaladeva (fl. c. 925-975) and Abhinavagupta (fl. c. 975-1025). The book shows that this system cannot be reduced to a mere scriptural exegesis and examines the genesis of the main concepts found in the Pratyabhij?± (Recognition) philosophy while taking into account the complexity of the philosophical field (already occupied by various currents, Buddhist as well as Brahmanical) in which Utpaladevas thought was developed.Si les r?©cents travaux de recherche consacr?©s au iva??sme ont permis de mieux comprendre les dimensions religieuses des mouvements iva??tes m?©di?©vaux, les aspects proprements philosophiques de certains des textes produits dans ces milieux demeurent largement m?©connus. La pr?©sent?© ?©tude se propose de contribuer ? combler cette lacune en explorant le syst??me philosophique complexe et original ?©labor?© par les iva??tes non dualistes cachemiriens Utpaladeva (925-975) et Abhinavagupta (975-1025). Montrant que ce syst??me ne se r?©duit pas ? une ex?©g??se scripturaire, louvrage examine la gen??se des concepts de la philosophie de la Pratyabhij?± ou Reconnaissance en prenant en compte la complexit?© du champ philosophique (d?©j? investi par divers courants aussi bien bouddhiques que brahmaniques) dans lequel la pens?©e dUtpaladeva sest d?©velopp?©e.
