This thesis will determine the public identity of Archbishop William King (1650-1729) of Dublin. This discussion will be framed in three distinct facets of his identity; ecclesiastical, political and philosophical. It will introduce crisis points in King's life and how his development was shaped as a result of these crises. His literary works will be analysed to illustrate his identity in the aforementioned areas. Through the analysis of his texts certain misconceptions will be addressed; his conversion, his political stance and his Lockeanism will be concluded upon. This thesis will situate King ecclesiastically, politically and philosophically to illustrate his tripartite identity. It will also argue that King was a late Scholastic thinker and not an early enlightenment philosopher, as has been previously assumed. The main methodological element present in his work was Scholasticism and throughout the thesis this will be proven to be correct. In each of the works examined the Scholastic method will be highlighted and traditional commonalities of reformed Scholastic thought will be identified. The thesis will conclude with a reflection on the public identity of William King and his scholasticism.
